Background Telemedicine services have been increasingly used to facilitate post-treatment cancer survivorship care, including improving access; monitoring health status, health behaviors, and symptom management; enhancing information exchange; and mitigating the costs of care delivery, especially since the COVID-19 pandemic. To inform guidance for the use of telemedicine in the post-COVID era, the aim of this overview of systematic reviews (SRs) was to evaluate the efficacy of, and survivor engagement in, telemedicine interventions in the post-treatment survivorship phase, and to consider implementation barriers and facilitators. Methods PubMed, Cochrane CENTRAL, CINAHL, Embase, and Web of Science databases were searched. SRs that examined the use of telemedicine in the post-treatment phase of cancer survivorship, published between January 2010 and April 2021, were included. Efficacy data were synthesized narratively. Implementation barriers and facilitators were synthesized using the Consolidated Framework for Implementation Research. Results Twenty-nine SRs were included. A substantive body of evidence found telemedicine to benefit the management of psychosocial and physical effects, particularly for improving fatigue and cognitive function. There was a lack of evidence on the use of telemedicine in the prevention and surveillance for recurrences and new cancers as well as management of chronic medical conditions. This overview highlights a range of diverse barriers and facilitators at the patient, health service, and system levels. Conclusions This review highlights the benefits of telemedicine in addressing psychosocial and physical effects, but not in other areas of post-treatment cancer survivorship care. This large review provides practical guidance for use of telemedicine in post-treatment survivorship care.

Purpose The purpose of this study is to investigate how different cancer-related symptoms influence work outcomes among cancer survivors. Methods A literature search was performed in PubMed, EMBASE, CINAHL, PsycINFO, and Scopus to identify studies published between 1st January 1999 and 30th October 2020 that investigated the impact of specific cancer-related symptoms on work outcomes among cancer survivors who have completed primary antineoplastic treatment. Study findings were extracted and grouped by symptoms and work outcomes, allowing comparison of associations between these outcomes. Results Seventy-three articles representing 68 studies were eligible for inclusion. From these studies, 27 cancer-related symptoms, 9 work outcomes, and 68 unique associations between specific symptoms and work outcomes were identified. Work status (return to work and employment rates) was most commonly studied, and symptom burden was mainly measured from the patient’s perspective. Higher symptom burden was generally associated with trends of poorer work outcomes. Significant associations were reported in most studies evaluating body image issues and work status, oral dysfunction and work status, fatigue and work ability, and depression and work ability. Conclusion Several cancer-related symptoms were consistently associated with inferior work outcomes among cancer survivors. Body image issues and oral dysfunction were shown to be associated with poorer employment rates, while fatigue and depression were linked to lower levels of work performance. Implications for Cancer Survivors Failure to return to work and decreased productivity post-cancer treatment can have negative consequences for cancer survivors and society at large. Findings from this review will guide the development of work rehabilitation programs for cancer survivors. Protocol registration PROSPERO identifier CRD42020187754

Background There exists scant evidence on the optimal approaches to integrating patient-reported outcomes (PROs) in clinical practice. This study gathered oncology practitioners’ experiences with implementing PROs in cancer care. Methods Between December 2019 and June 2020, we surveyed practitioners who reported spending > 5% of their time providing clinical care to cancer patients. Respondents completed an online survey describing their experiences with and barriers to using PROs in clinical settings. Results In total, 362 practitioners (physicians 38.7%, nurses 46.7%, allied health professionals 14.6%) completed the survey, representing 41 countries (Asia–Pacific 42.5%, North America 30.1%, Europe 24.0%, others 3.3%). One quarter (25.4%) identified themselves as “high frequency users” who conducted PRO assessments on > 80% of their patients. Practitioners commonly used PROs to facilitate communication (60.2%) and monitor treatment responses (52.6%). The most commonly reported implementation barriers were a lack of technological support (70.4%) and absence of a robust workflow to integrate PROs in clinical care (61.5%). Compared to practitioners from high-income countries, more practitioners in low-middle income countries reported not having access to a local PRO expert (P

To evaluate for inter-individual differences in financial distress and identify demographic, clinical, and symptom characteristics associated with higher levels of financial distress. Patients (n = 387) were enrolled prior to breast cancer surgery and followed for 12 months. Financial distress was measured using a 0 (no problem) to 10 (severe problem) numeric rating scale. Hierarchical linear modeling was used to evaluate for inter-individual differences in trajectories of financial distress and characteristics associated with financial distress at enrollment and over 12 months. Patients’ mean age was 55.0 (± 11.7) years and the majority underwent breast conservation surgery (80.6%). Mean financial distress score prior to surgery was 3.3 (± 3.4; range 0 to 10). Unconditional model for financial distress demonstrated no significant changes over time (-0.006/month). Younger age, lower income, receipt of an axillary lymph node dissection and adjuvant chemotherapy, and lower attentional function were associated with higher preoperative levels of financial distress. Risk factors identified in this study can be used to inform clinicians regarding the need to initiate financial discussions and social work referrals for some patients. Additional clinical or system level interventions should be considered for vulnerable groups with these risk factors.

PURPOSE Breast cancer survivors often manifest comorbidities that require medication management. This study aimed to investigate the prescription patterns of drugs prescribed frequently among breast cancer survivors and to provide data to monitor adverse effects using other covariates in these patients. MATERIALS AND METHODS We analyzed a Korean national sample cohort database. The diagnosis of breast cancer, survival, survival duration, and frequency of drug prescription were first defined and extracted. We then analyzed the frequency of drug prescription in breast cancer by survival duration. Factors associated with drug prescribing patterns were analyzed using logistic regression analysis. RESULTS Among 2,410 breast cancer survivors, anti-hormonal agents, gastrointestinal drugs, calcium, and anxiolytics were most frequently prescribed. Gastrointestinal disturbance and depression are most commonly observed among breast cancer survivors. Survivors who were 3 to < 5 years post treatment were frequently prescribed calcium. In addition to gastrointestinal drugs, anxiolytics were frequently prescribed among survivors manifesting comorbidities. In addition to anti-hormone agents, which were frequently prescribed to breast cancer patients, gastrointestinal drugs were the second most frequently prescribed, and anxiolytics were often co-prescribed. Calcium was also frequently co-prescribed in patients requiring anti-depressants. CONCLUSION In the Korean National Cohort, gastrointestinal drugs, calcium, and anxiolytics were frequently prescribed to older patients, suggesting that older patients diagnosed with cancer experience a wide array of toxicities requiring supportive care.

Study objective To evaluate a surveillance protocol in managing the risk of hepatitis B virus (HBV) reactivation among lymphoma patients with resolved HBV infection receiving rituximab. Design Prospective, single-arm study. Setting National Cancer Centre, Singapore. Patients Lymphoma patients with resolved HBV infection and scheduled to receive rituximab-based treatment. Intervention Close monitoring of HBV DNA levels, ie. every 4-6 weeks during rituximab treatment, every 6-8 weeks in the first year post-treatment, and every 3-4 months in the second year post-treatment. Measurements The efficacy of the surveillance protocol was examined by evaluating the rates of reactivation-related events. Feasibility was evaluated based on patient adherence. An economic analysis using a cost-minimization approach was conducted to compare the costs between the surveillance protocol and universal prophylaxis with entecavir 0.5 mg daily up to 1 year after cessation of rituximab. Main results A total of 66 patients provided analyzable data with a follow-up period of 966.6 months. No hepatitis flare or reactivation-related events were detected. The median adherence rate to the surveillance protocol was 90.5%. Cost savings of US$946.40 per patient over the entire surveillance period were achieved if the surveillance protocol was adopted and was most affected by changes in prophylaxis duration and the cost of antiviral prophylaxis. Conclusions The surveillance protocol is an effective, feasible and cost-saving strategy to manage HBV reactivation among lymphoma patients with resolved HBV infection receiving rituximab.

Response, action, and adaptation of the way health services are delivered will impact our ability to provide optimized and continuity of care while acting within resource constraints imposed by COVID-19. Care for patients with cancer is particularly important given increased infection rates and worse outcomes from COVID-19 in this patient population, as well as potential adverse outcomes if treatment pathways need to be compromised. In this commentary, we provide a global oncology pharmacy perspective (including both developed and developing nations) on how COVID-19 has impacted access to and delivery of cancer therapies. This perspective was prepared by the International Society of Oncology Pharmacy Practitioners, with input from national and regional oncology pharmacy practice groups (42 practice leaders from 28 countries and regions) who contributed to a snapshot survey between 10 and 22 April 2020. Specifically, we highlight challenges related to safe handling of hazardous drugs and maintaining high-quality medication safety standards that have impacted various stakeholders.

PURPOSE: The role of mobile health (mHealth) technology in cancer care has evolved alongside the rapid development in digital technology. Its use can come with significant potential benefits; however, such use may also be associated with risks. This paper summarizes the latest developments around mHealth use in cancer care presented by a panel of experts at the 2019 Annual Meeting of the Multinational Association of Supportive Care in Cancer. METHODS: Through lectures, case studies, and panel discussions, speakers and participants (including cancer specialist doctors, nurses, and allied health professionals) evaluated current and emerging mHealth methods for supportive care in cancer survivorship. Focus areas and special considerations were agreed upon by consensus. RESULTS: Three focus areas for the use of mHealth in cancer care were identified: activation and support of self-management, exercise oncology, and enablement of survivorship care delivery. In addition to these focus areas, two special considerations were highlighted: technology-enhanced supportive cancer care for disparate populations, and ethical considerations relevant to the use of technology in supportive care. CONCLUSION: mHealth has the potential to revolutionize and transform cancer care delivery. Future research should guide further advances in the use of technology in supportive cancer care and carefully explore the safety, efficacy, cost-effectiveness, and implementation of interventions delivered through mHealth platforms.

Work-related issues among Asian adolescent and young-adult (AYA) cancer survivors are poorly described in the literature. There has also been a paucity of reports regarding insurance-related concerns in this patient population. Focus groups were therefore carried out in Singapore to understand survivorship issues related to work and insurance coverage among Asian AYA cancer survivors. Twenty-three AYA survivors and 18 healthcare professionals (HCPs) who care for AYA cancer patients were recruited for 11 focus group sessions. Thematic content analysis was carried out to identify major themes that emerged. Similar themes emerged from AYA and HCP focus groups. The majority of AYA survivors were eager to return to work post-treatment. However, some survivors were worried about not keeping up with expectations and struggled with disclosure of their medical history. In contrast, several survivors leveraged on their experience with cancer to bolster job opportunities. Despite facing challenges due to complications from cancer and restrictions at work, AYA survivors preferred to be treated normally. AYA survivors also expressed concerns about inadequate insurance coverage and a lack of information on this topic. Contrary to expectations, Asian AYA survivors are motivated to return to work and address work-related challenges. Inadequate insurance coverage remains a pressing concern despite the availability of public health insurance and subsidies. Career coaches and financial counselors should be incorporated into survivorship care to aid AYA survivors.

With the development of innovative cancer treatments over recent decades, the cost of cancer care has risen exponentially, limiting patient access to patented originator biotherapeutics in many countries. The introduction of biosimilars to the market has created new opportunities as well the need for changes in practice within healthcare institutions. A ‘biosimilar’ is a biotherapeutic product which is highly similar in terms of quality, safety and efficacy to an already licensed originator product. Although biosimilars lack clinically meaningful differences in therapeutic activity as compared to the originator product, these complex biological molecules are not considered identical chemical copies, unlike generics, and minor differences in molecular structure and inactive compounds may exist. A thorough understanding of these differences and their clinical implications is necessary for optimising medicines-use practices involving biosimilars. This position statement, developed by the International Society of Oncology Pharmacy Practitioners Biosimilars Taskforce, aims to provide the global oncology pharmacy community with guidance to support decisions around biosimilar use. The 11 statements cover the regulation and evaluation of biosimilars, practical issues around local implementation, the education of healthcare staff and patients, and the requirement for ongoing pharmacovigilance and outcome monitoring.

Background Breast cancer is prevalent and has high cure rates. The resultant increase in numbers of breast cancer survivors (BCS) may overwhelm the current oncology workforce in years to come. We postulate that primary care physicians (PCPs) could play an expanded role in comanaging survivors, provided they are given the appropriate tools and training to do so. Objective To explore the perspectives of PCPs towards managing BCS in a community-based shared-care programme with oncologists. Methods Eleven focus groups and six in-depth interviews were conducted with seventy PCPs recruited by purposive sampling. All sessions were audio-recorded, transcribed verbatim and coded by three independent investigators. Thematic data analysis was performed and the coding process facilitated by NVivo 12. Results Majority of PCPs reported currently limited roles in managing acute and non-cancer issues, optimizing comorbidities and preventive care. PCPs aspired to expand their role to include cancer surveillance, risk assessment and addressing unmet psychosocial needs. PCPs preferred to harmonize cancer survivorship management of their primary care patients who are also BCS, with defined role distinct from oncologists. Training to understand the care protocol, enhancement of communication skills, confidence and trust were deemed necessary. PCPs proposed selection criteria of BCS and adequacy of their medical information; increased consultation time; contact details and timely access to oncologists (if needed) in the shared-care programme. Conclusions PCPs were willing to share the care of BCS with oncologists but recommended role definition, training, clinical protocol, resources and access to oncologist’s consultation to optimize the programme implementation.

Introduction The coronavirus of 2019 pandemic has necessitated vast and rapid changes in the way oncology pharmacy services are delivered around the world. Methods/aims An international survey of oncology pharmacists and technicians was conducted via the International Society of Oncology Pharmacy Practitioners and collaborating global pharmacy organisations to determine the impact that the coronavirus of 2019 has had on pharmacy service delivery, pharmacy practitioners and oncology practice. Results The survey received 862 responses from 40 different countries from September to October 2020. The majority of respondents were pharmacists ( n = 841, 97.6%), with 24% involved in the direct care of patients with the coronavirus of 2019. Of the survey participants, 55% increased their time working remotely, with remote activities including dispensing, patient assessment/follow-up and attending multi-disciplinary rounds. Respondents reported a 72% increase in the use of technology to perform remote patient interaction activities and that participation in educational meetings and quality improvement projects was reduced by 68% and 44%, respectively. Workforce impacts included altered working hours (50%), cancelled leave (48%) and forced leave/furloughing (30%). During the pandemic, respondents reported reduced access to intensive care (19%) and anti-cancer (15%) medications. In addition, 39% of respondents reported reduced access to personal protective equipment, including N95 masks for chemotherapy compounding. Almost half of respondents (49%) reported that cancer treatments were delayed or intervals were altered for patients being treated with curative intent. A third of practitioners (30%) believed that patient outcomes would be adversely impacted by changes to pharmacy services. Sixty-five percent of respondents reported impacts on their mental health, with 12% utilising support services. Conclusion The coronavirus of 2019 pandemic has altered the way oncology pharmacy services are delivered. These results demonstrate the adaptability of the oncology pharmacy profession and highlight the importance of formal evaluation of the varied practice models to determine the evidence-based practices that enhance pharmacy services and, thus, should be reinstated as soon as practical and reasonable.

Despite numerous challenges in relation to being a recently established school, the University of California, Irvine (UCI) School of Pharmacy and Pharmaceutical Sciences (SPPS), similar to many schools of pharmacy in the United States, was highly committed to supporting the rollout of COVID-19 vaccines. UCI SPPS and our affiliated UCI Medical Center (UCIMC) Pharmacy Department partnered to spearhead the pharmacy element of a large-scale COVID-19 vaccination clinic on campus for both employees and the community. Three key initiatives were established in order to overcome the obstacles we faced in the large-scale roll out of COVID-19 vaccines: (1) forging new collaborations within the pharmacy team, (2) leveraging interprofessional education and practice, and (3) raising awareness of the pharmacists’ role. Our response to the COVID-19 vaccines at UCI was a tangible, visible model that demonstrated that, while we continue to embrace our role in team-based, patient-centered care, it is also important for us to step up and lead the profession. Additionally, this vaccine rollout experience is a teachable moment for our communities and our health professional partners as we continue to march forward as one voice to serve the American public.

Cytokines facilitate the peripheral immune and cerebral response, through their ability to modulate the expression of brain derived neurotrophic factor (BDNF). Cytokines and BDNF are implicated in cancer-related cognitive impairment (CRCI), but their relationship has not been clearly defined for this condition. The aim of this study was to evaluate the associations of cytokines and BDNF among early stage breast cancer (ESBC) patients with different CRCI trajectories. This was a multicenter longitudinal study involving 136 ESBC patients. CRCI was assessed using the FACT-Cog (V3) questionnaire. Plasma cytokines and BDNF levels were quantified at three time points throughout chemotherapy. The associations between cytokines and BDNF were analyzed using linear mixed models, with interaction terms for CRCI status. All cytokines analyzed showed inverse associations with BDNF levels. There was a significant interaction between IL-6 and the persistent impairment trajectory, which would impact on BDNF levels (p=0.026). The inverse associations with BDNF were more pronounced for IFN-γ, IL-1β, IL-4, IL-8, and GM-CSF in patients with persistent CRCI. The coefficient values for IL-2, IL-4, and TNF-α also indicate that there was a greater magnitude of decrease in BDNF level for every unit of cytokine increase in patients with acute and persistent CRCI, compared to patients without CRCI. The differential associations between cytokines and BDNF may be indicative of probable susceptibility to the elevation of cytokines. Further research is required to elucidate the specific associations of cytokines and BDNF, along with their contributions to acute and persistent CRCI.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common and debilitating condition associated with a number of chemotherapeutic agents. Drugs commonly implicated in the development of CIPN include platinum agents, taxanes, vinca alkaloids, bortezomib, and thalidomide analogues. As a drug response can vary between individuals, it is hypothesized that an individual's specific genetic variants could impact the regulation of genes involved in drug pharmacokinetics, ion channel functioning, neurotoxicity, and DNA repair, which in turn affect CIPN development and severity. Variations of other molecular markers may also affect the incidence and severity of CIPN. Hence, the objective of this review was to summarize the known biological (molecular and genomic) predictors of CIPN and discuss the means to facilitate progress in this field.

Cancer‐related fatigue (CRF) is subjective and has wide inter‐individual variability. Given that leptin is commonly associated with fatigue syndrome, its use as a potential biomarker for CRF is being investigated. The primary objective of this study was to evaluate the association between leptin and CRF in early‐stage breast cancer patients receiving chemotherapy. In a prospective cohort study, patients completed assessments at baseline (T1), during chemotherapy (T2) and after chemotherapy (T3). Levels of plasma leptin and adipokines were measured using a Luminex bead‐immunoassay and CRF was measured using the Multi‐Dimensional Fatigue Symptom Inventory‐Short Form (MFSI‐SF). Data were analysed longitudinally using a generalised estimating equation incorporating clinically relevant parameters and pro‐inflammatory adipokines. The analysis included 136 patients (mean age ± SD = 51.5 ± 8.8 years; 69.1% receiving anthracycline‐based chemotherapy). More patients experienced CRF at T3 (23.8%) than at T2 (13.8%) compared to baseline. An increase was observed in the median plasma leptin level at T2, followed by a decrease at T3 (T1: 4.07 ng/mL, T2: 4.95 ng/mL and T3: 3.96 ng/mL). In the multivariate model, the change in leptin levels over time was significantly associated with the total MFSI‐SF score (β = −0.15, P = 0.003) after adjusting for the tumour necrosis factor‐α (TNF‐α) level, anxiety, depression, insomnia, age, menopausal status and type of chemotherapy. This is the first study to report leptin as a biomarker that predicts the onset of CRF over time. Future studies are required to validate the findings.

Author(s): Toh, Yi Long; Shariq Mujtaba, Juliana; Bansal, Sumit; Yeo, Angie; Shwe, Maung; Lau, Aik Jiang; Chan, Alexandre | Abstract: Study objectiveDehydroepiandrosterone (DHEA) and its sulfated form (DHEAS)-jointly referred to as DHEA(S)-are neurosteroids known to regulate brain development and function that have been found to be positively correlated with cognitive function. It is unknown whether prechemotherapy plasma DHEA(S) levels are associated with the onset of cancer-related cognitive impairment (CRCI). The objective of this study was to evaluate whether an association exists between prechemotherapy plasma DHEA(S) levels and onset of CRCI in patients with breast cancer receiving chemotherapy.DesignMulticenter, prospective cohort study.SettingTwo specialized cancer centers in Singapore.PatientsEighty-one patients with early-stage breast cancer (stages I-III) who had no prior exposure to chemotherapy and/or radiotherapy and were scheduled to receive anthracycline-based or taxane-based chemotherapy treatment with curative intent.Measurements and main resultsPatients completed assessments for self-perceived and objective cognitive function at three time points: prechemotherapy (T1), during chemotherapy (T2), and after chemotherapy (T3). Plasma samples were collected prior to chemotherapy, and DHEA(S) levels were quantified by using ultra-high-performance liquid chromatography-tandem mass spectrometry. Multivariable logistic regression was used to adjust for clinically important factors and to evaluate the association between prechemotherapy plasma DHEA(S) levels and CRCI. Meann±nSD age was 48.9n±n9.3nyears, with 27.8% of patients experiencing clinically significant cognitive impairment based on global Functional Assessment of Cancer Therapy-Cognitive Function scores. The meann±nSD prechemotherapy plasma DHEAS and DHEA levels were 1.61n±n0.91nμmol/L and 19.21n±n13.13nnmol/L, respectively. Prechemotherapy DHEAS levels were found to be associated with impairment in the self-perceived cognitive domains of verbal fluency (adjusted odds ratio [OR] 0.27, 95% confidence interval [CI] 0.08-0.96) and mental acuity (adjusted OR 0.25, 95% CI 0.08-0.74). Conversely, DHEA levels were not associated with impairment in any cognitive subdomains.ConclusionOur findings suggest that patients with higher prechemotherapy DHEAS levels had lower odds of developing self-perceived cognitive impairment. Future studies are required to further investigate the effect of DHEA(S) on specific cognitive domains and to validate our findings in independent cohorts.

The Oncology Pharmacy Team (OPT), consisting of specialty-trained pharmacists and/or pharmacy technicians, is an integral component of the multidisciplinary healthcare team (MHT) involved with all aspects of cancer patient care. The OPT fosters quality patient care, safety, and local regulatory compliance. The International Society of Oncology Pharmacy Practitioners (ISOPP) developed this position statement to provide guidance on five key areas: 1) oncology pharmacy practice as a pharmacy specialty; 2) contributions to patient care; 3) oncology pharmacy practice management; 4) education and training; and 5) contributions to oncology research and quality initiatives to involve the OPT. This position statement advocates that: 1) the OPT be fully incorporated into the MHT to optimize patient care; 2) educational and healthcare institutions develop programs to continually educate OPT members; and 3) regulatory authorities develop certification programs to recognize the unique contributions of the OPT in cancer patient care.

Cognitive impairment due to cancer and its therapy is a major concern among cancer patients and survivors. Extracellular vesicle (EVs) composition altered by cancer and chemotherapy may affect neurological processes such as neuroplasticity, potentially impacting the cognitive abilities of cancer patients and survivors. We investigated the EV proteome of breast cancer patients with and without cognitive impairment following anthracycline-based chemotherapy from longitudinally collected plasma. EVs were cup-shaped and positive for Flotillin-1 and TSG-101. We identified 517 differentially expressed EV proteins between the cognitive impaired and non-impaired groups during and post-chemotherapy. The observed decreased expression of p2X purinoceptor, cofilin-1, ADAM 10, and dynamin-1 in the plasma EVs of the cognitive impaired group may suggest alterations in the mechanisms underlying synaptic plasticity. The reduced expression of tight junction proteins among cognitive-impaired patients may imply weakening of the blood-brain barrier. These EV protein signatures may serve as a fingerprint that underscores the mechanisms underlying cognitive impairment in cancer patients and survivors.

Pharmacological treatment of chemotherapy-induced peripheral neuropathy (CIPN) is still in its infancy and available options are limited. Both American Society of Clinical Oncology (ASCO) and European Society of Medical Oncology-European Oncology Nursing Society-European Association of Neuro-Oncology (ESMO-EONS-EANO) guidelines recommend the use of duloxetine for treatment of CIPN. The ESMO-EONS-EANO suggest gabapentinoids (pregabalin and gabapentin), tricyclic antidepressants, and opioids may be considered as an option to relieve neuropathic pain where duloxetine cannot be used. The National Comprehensive Cancer Network (NCCN) guidelines do not address CIPN specifically, but consider gabapentinoids (pregabalin and gabapentin) first-line options for cancer-related neuropathic pain. Currently, none of these guidelines recommend the use of any supplements but they recommend against use of acetyl-l-carnitine due to harm seen in preventions studies. The ESMO guidelines also recommend use of topical menthol but recommend against the use of topical ketamine and amitriptyline. Despite limited options currently available, multiple studies are ongoing and further treatment choices may become available in the future.

Introduction: We conducted a randomized controlled trial evaluating the efficacy and tolerability of cryotherapy in preventing chemotherapy-induced peripheral neuropathy (CIPN) in patients with early breast cancer receiving neo/adjuvant weekly paclitaxel.Methods: Patients were recruited from the National Cancer Centre Singapore and randomized (1:1) to receive either cryotherapy or usual care. Cryotherapy was applied as frozen gloves and socks on all extremities from 15 min before paclitaxel until 15 min post-infusion every cycle. Efficacy was measured by patient-reported outcomes (Patient Neurotoxicity Questionnaire [PNQ] and EORTC QLQ-CIPN20) and electrophysiological assessments. The primary endpoint was PNQ severity at 2 weeks after 12 cycles of weekly paclitaxel.Results: A total of 46 patients were recruited, of which 8 dropped out before paclitaxel treatment, leaving 38 evaluable. There was no significant difference in PNQ severity between cryotherapy and usual care at 2 weeks after paclitaxel treatment (sensory: p = 0.721; motor: p = 1.000). A benefit was observed at 3 months post-paclitaxel based on PNQ (sensory: 14.3 vs. 41.2%, p = 0.078; motor: 0 vs. 29.4%, p = 0.012) and CIPN20 (sensory: β = −3.6, 95%CI = −10.5–3.4, p = 0.308; motor: β = −7.3, 95%CI = −14.6–0, p = 0.051). Additionally, cryotherapy subjects have lower CIPN20 autonomic score (β = −5.84, 95%CI = −11.15 to −0.524, p = 0.031) and higher sympathetic skin response hand amplitudes (β = 0.544, 95%CI = 0.108–0.98, p = 0.014), suggesting possible autonomic benefits from cryotherapy. Temporary interruption with cryotherapy occurred in 80.9% of the subjects due to cold intolerance.Conclusions: There is insufficient evidence that cryotherapy prevents sensory neuropathy which may be due to the high rates of cryotherapy interruption in this study. The autonomic benefits of cryotherapy should be further investigated with appropriate outcome measures.Clinical Trial Registration:ClinicalTrials.gov: NCT03429972.

Background Cancer-related fatigue (CRF) is a debilitating condition which commonly affects cancer survivors. The management of CRF remains a challenge due to the lack of effective pharmacological interventions. Traditional Chinese medicine (TCM) could be a potential therapeutic option for CRF. The modified Xiang Bei Yang Rong Tang (XBYRT) is a TCM herbal decoction, formulated to improve fatigue symptoms in cancer survivors. This clinical trial aims to evaluate the efficacy and safety of XBYRT in improving CRF and quality of life (QOL) of cancer survivors. Methods This is a single centre, randomized, double-blind, placebo-controlled, parallel trial. Eighty cancer survivors will be recruited and randomized to receive the XBYRT or placebo decoction, in a ratio of 1:1. Participants will consume the XBYRT/placebo decoction daily for 8 weeks and undergo assessments at baseline and 4, 8 and 10 weeks after baseline. The participants will be assessed for patient-reported outcomes (PRO), blood biomarkers and adverse events at each time point. The primary outcome is the overall health and QOL status, at 8 weeks follow-up. The secondary outcomes are the effects of XBYRT on fatigue levels, cancer-related cognitive impairment and QOL, as assessed by PRO. The incidence of adverse events and the effects of the XBYRT decoction on blood biomarkers associated with CRF will also be evaluated. Discussion Efficacy and safety outcomes from this trial will provide important clinical data to guide future large-scale randomized controlled trials, and the evaluation of the objective blood biomarkers can help to delineate the biological mechanisms of CRF.

Cancer-related cognitive impairment (CRCI) is commonly experienced by individuals with non- central nervous system cancers throughout the disease and treatment trajectory. CRCI can have a substantial impact on the functional ability and quality of life of patients and their families. To mitigate the impact, oncology providers must know how to identify, assess, and educate patients and caregivers. The objective of this review is to provide oncology clinicians with an overview of CRCI in the context of adults with non-central nervous system cancers, with a particular focus on current approaches in its identification, assessment, and management.

Background The aim of this study was to evaluate the psychometric properties of the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group—Neurotoxicity (FACT/GOG-Ntx) subscale in a longitudinal study of cancer patients treated with chemotherapy. Methods Patients were assessed with the FACT/GOG-Ntx subscale, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Chemotherapy-Induced Peripheral Neuropathy Scale 20 (EORTC QLQ-CIPN20), National Cancer Institute -Common Terminology Criteria for Adverse Events (NCI-CTCAE), and light touch test using 10 g monofilament for up to ten assessment points from baseline (prior to initiation of first chemotherapy), after the end of each cycle (up to 6 cycles, 3 weeks per cycle), and at 6, 9, and 12 months after starting chemotherapy. Psychometric analyses included internal consistency reliability, convergent validity, factorial validity, sensitivity to change and responsiveness (minimal clinically important difference, MCID). Results Cronbach’s alpha coefficients of the FACT/GOG-Ntx subscale were 0.82–0.89 across assessment points. The subscale strongly correlated with the EORTC QLQ-CIPN20 (r = 0.79–0.93) but low-to-moderately correlated with the NCI-CTCAE sensory (rs = 0.23–0.45) and motor items (rs = 0.15–0.50) as well as the monofilament test (rs = 0.23–0.47). The hypothesized 4-factor structure of the FACT/GOG-Ntx subscale was not confirmed at assessment points (χ2/df = 2.26–8.50; all P r = 0.17–0.37). The MCIDs were between 1.38 and 3.68. Conclusion The FACT/GOG-Ntx subscale has satisfactory reliability, validity, sensitivity to change and responsiveness to evaluate CIPN in cancer patients. Future research is needed to explore the factorial structure of the FACT/GOG-Ntx subscale as the published four-factor structure was not supported in this study.

This editorial draws on the authors’ experiences and the results of a survey of cancer professionals to contextualize the major disruptions taking place globally in survivorship care as a result of the COVID-19 pandemic. Cancer survivors’ follow-up care has been severely affected due to increased risk of infection associated with hospital attendance, limited workforce availability and other resource constraints, implementation of new protocols to screen patients impacting workflow, and concerns of patients and health care providers about risk of infection [1]. Evidence-based recommendations on how to manage cancer survivors in a pandemic are lacking and much of the general guidance (such as CDC guidelines) [2] suggests that clinic visits for cancer survivors, including routine surveillance visits to detect cancer recurrence, should be postponed [3]. Such a situation is problematic especially if the pandemic is long lasting, leaving important survivorship issues and concerns unaddressed. In the absence of appropriate guidelines, cancer survivors are at increased risk of inappropriate or inconsistent follow-up care that could have far-reaching and even life-threatening results.

Background The International Society of Oncology Pharmacy Practitioners (ISOPP) Biosimilar Task Force was charged to develop educational resources to address the learning needs related to biosimilars use of oncology pharmacy practitioners. To facilitate the process, the task force conducted a survey in order to identify unmet education needs as well as barriers for obtaining biosimilar education among oncology pharmacy practitioners. Methods A cross sectional survey was conducted between 10 December 2018 and 18 February 2019. Members of International Society of Oncology Pharmacy Practitioners and national oncology pharmacy groups were invited to complete the survey. The survey contained 22 items and consisted of four sections. Descriptive statistics were utilized to analyze the survey results. Results A total of 363 International Society of Oncology Pharmacy Practitioners members were surveyed, with 75 members providing a response (response rate = 21%). In addition, 11 non-International Society of Oncology Pharmacy Practitioners members also participated in the survey, bringing the total to 86 respondents. The top three areas in which respondents reported learning needs included evaluating comparative efficacy of a biosimilar to an originator’s product (74.4%), managing the switchover to a biosimilar from the original product (74.4%), and understanding medication safety issues in relation to biosimilars use (73.3%). The most common challenges faced in obtaining education on biosimilars included limited financial support for education on biosimilar products (38.4%), heavy workload (31.4%), and inadequate educational resources (27.9%). Conclusion This survey has identified numerous biosimilar learning needs as well as challenges faced in obtaining biosimilars education among oncology pharmacy practitioners. Educational activities should be created to address these learning needs, and innovative strategies should be considered to overcome practitioner’s barriers in obtaining biosimilars education.

The International Society of Oncology Pharmacy Practitioners organized a workshop to create learning opportunities on biosimilars in pharmacy practice on 10 October 2019. The topics that were covered included (i) the development and testing of biosimilars, (ii) the challenges of bringing biosimilars to market, and (iii) real-world data on patient safety and perceptions during biosimilar implementation. The development of biosimilars can take up to eight years and the extensiveness of the process depends on several factors, such as the complexity of the production process and regulatory requirements. Compared to generic products of small-molecule drugs, there is a higher barrier to market entry for biosimilars, explaining the small number of biosimilars in the market. Appraisal of biosimilars for inclusion in hospital formularies is also different from the review process of originator biologics, where the former is usually institution-led and has fewer restrictions on use. When several biosimilar products are available, factors that should be considered besides cost are licensed indications, supply chain confidence, clinical data, and product attributes. Real-world data have shown that biosimilars are well-tolerated and have safety data that are comparable to that of the originator product. Oncology pharmacists from the United Kingdom, Kenya, and Canada also presented their respective experiences with biosimilar use. Different countries at varying stages of biosimilar implementation faced distinct challenges. Nevertheless, resources to assist biosimilar implementation can potentially be shared between different regions. International Society of Oncology Pharmacy Practitioners is well-positioned to foster professional cooperation at an international level to drive biosimilar implementation.

Background The International Society of Oncology Pharmacy Practitioners (ISOPP) Biosimilars Task Force was charged to develop educational activities and resources to assist members when implementing biosimilar medicines into their local practice. To facilitate the process, the task force conducted a survey in order to understand biosimilar implementation practice by ISOPP members across the world and the challenges that oncology pharmacists face when adopting biosimilars into their clinical practice. Methods A cross-sectional survey was conducted between 20 April 2019 and 27 May 2019. Members of ISOPP and a number of national oncology pharmacy groups were invited to complete the survey. The survey contained 29 items and consisted of three sections: respondents’ demographics, respondents’ institutional practice relating to biosimilar implementation and post implementation practice at the respondents’ institutions. Descriptive statistics were utilized to analyze the survey results. Results A total of 265 ISOPP members were surveyed, with 50 members providing a response (response rate = 19%). In addition, 40 nonmembers participated in the survey, bringing the total to 90 respondents. The most common factors that influence the decision to implement use of a biosimilar as reported by respondents are medication costs/pricing (92%), available clinical data (73%), and product availability (63%). Respondents also commented on the barriers to biosimilar implementation at their institutions, which included a reluctance of prescribers to use biosimilars (due to the lack of familiarity or perceived inferiority), a reluctance to switch established patients from an originator to a biosimilar and the preferences of insurance companies or funding bodies. Conclusion The results of this survey reinforce the need for greater education and training for health care professionals in the use of biosimilars, the importance of sharing good practice, and a need for standardization.

A decline in cognitive function following cancer treatment is one of the most commonly reported post-treatment symptoms among patients with cancer and those in remission, and include memory, processing speed, and executive function. A clear understanding of cognitive impairment as a result of cancer and its therapy can be obtained by delineating structural and functional changes using brain imaging studies and neurocognitive assessments. There is also a need to determine the underlying mechanisms and pathways that impact the brain and affect cognitive functioning in cancer survivors. Exosomes are small cell-derived vesicles formed by the inward budding of multivesicular bodies, and are released into the extracellular environment via an exocytic pathway. Growing evidence suggests that exosomes contribute to various physiological and pathological conditions, including neurological processes such as synaptic plasticity, neuronal stress response, cell-to-cell communication, and neurogenesis. In this review, we summarize the relationship between exosomes and cancer-related cognitive impairment. Unraveling exosomes’ actions and effects on the microenvironment of the brain, which impacts cognitive functioning, is critical for the development of exosome-based therapeutics for cancer-related cognitive impairment.

Brain-derived neurotrophic factor (BDNF) and the BDNF Val66Met polymorphism (rs6265) have been implicated in neurodegenerative conditions. This study aimed to investigate the associations of plasma BDNF and rs6265 with cancer-related cognitive impairment (CRCI) at the end of chemotherapy, and with persistent and delayed CRCI up to 24 months post chemotherapy, among survivors of early-stage breast cancer. A multicenter, longitudinal study involving 174 breast cancer patients was conducted. CRCI was assessed using the FACT-Cog (V3) questionnaire and the CANTAB software. Plasma BDNF levels were quantified using an enzyme-linked immunosorbent assay at serial time points and genotyping was achieved using Sanger sequencing. The associations of BDNF and rs6265 with CRCI were analyzed using logistic regressions. A smaller magnitude of reduction in plasma BDNF between baseline and the end of chemotherapy was correlated with protection from overall subjective CRCI (OR 0.88; 95% CI 0.79–0.99). Furthermore, patients with higher plasma BDNF levels at the end of chemotherapy had lower odds of developing persistent overall subjective CRCI (OR 0.74; 95% CI 0.57–0.97) and persistent CRCI in the functional interference domain (OR 0.62; 95% CI 0.39–0.98). BDNF Met allele carriers were protected against subjective CRCI at the end of chemotherapy in the multitasking and memory domains, and against persistent subjective CRCI in the mental acuity and multitasking domains. BDNF plasma level or rs6265 genotype information may facilitate the identification of patients at higher risk of long-term CRCI during survivorship and enable the implementation of early intervention strategies that increase BDNF levels.

Background and purposeConducting peer assessment has been associated with positive learning outcomes in higher education. The primary objective was to evaluate pharmacy students' perceptions of using peer assessment as a pedagogical strategy in learning patient presentation skills. Secondary objectives were to determine helpful factors for providing and/or receiving peer assessment and to compare students' perceptions of peer assessment relative to receiving feedback from teaching assistants (TAs).Educational activity and settingPatient presentation skills were taught to third-year pharmacy students in three sessions (session 1: didactic lecture, session 2: faculty-led patient presentation workshops followed by peer assessment, session 3: one-on-one patient presentations to TAs). An anonymous survey instrument consisting of five-point Likert scale, yes/no, and open-ended questions was administered.FindingsA total of 187 students (98%) completed the survey. Peer assessment was perceived as a useful way to obtain feedback on patient presentations (87%). It facilitated higher level thinking and a self-reflection of students' own patient presentations. Most students felt that they received constructive feedback from peers (82%) that helped them improve their patient presentation skills (72%). However, students were more trusting of TAs' skills in assessing patient presentations (76% versus 93%, p

PurposeA breast cancer diagnosis has a substantial economic impact. Study aims were to evaluate for inter-individual differences in cancer's level of interference with employment and identify phenotypic and symptom characteristics associated with higher levels of interference.MethodsPatients (n= 387) were enrolled prior to breast cancer surgery and followed for 12months. Interference with employment was measured using a 0 (no problem) to 10 (severe problem) numeric rating scale. Hierarchical linear modeling (HLM) was used to evaluate for inter-individual differences in trajectories of employment interference and characteristics associated with employment interference at enrollment and over 12months.ResultsPatients' mean age was 55.0 (±11.7) years and the majority underwent breast conservation surgery (80.6%). Mean employment interference score was 3.2 (±3.7). Unconditional model for employment interference demonstrated a decreasing linear trend (-.076/month). Younger age, lower income, higher pain intensity, and having an axillary lymph node dissection were associated with higher pre-surgical interference scores. Having a sentinel lymph node biopsy was associated with ongoing employment interference scores. Higher sleep disturbance scores were associated with both initial and ongoing employment interference scores. Receipt of chemotherapy, use of complementary or alternative therapies, and re-excision or mastectomy following surgery were significant time varying covariates.ConclusionThis study is the first to use HLM to describe inter-individual differences in the trajectories of cancer's interference with employment and associated factors prior to and for 12months following breast cancer surgery. Patients with the identified risk factors warrant ongoing assessments of employment interference and appropriate referrals.

Purpose: With an increasing focus on developing survivorship services tailored for adolescent and young adult (AYA) cancer survivors, incorporation of viewpoints from both survivors and health care professionals (HCPs) is important. This study aims to explore the perceptions of current and prospective survivorship services from both groups in Singapore to propose service design and delivery strategies. Methods: Focus group discussions with 23 AYA cancer survivors between the ages of 16 and 39 years at diagnosis and 18 HCPs were conducted in National Cancer Centre Singapore (NCCS) and Singapore Cancer Society (SCS). All focus group discussions were transcribed verbatim. Deductive thematic analysis was performed according to the components of a design thinking model: empathizing with AYA survivors, defining care gaps, proposing services, and implementation strategies. Results: AYA survivors preferred age-specific services that are aligned with their personal goals. Current survivorship care failed to address the needs of survivors' dependents (caregivers and children) and to consider the utility of each service temporally. Prospective services should clarify disease disclosure obligation in job search and introduce a care navigator. Key implementation strategies included (1) training HCPs on communication techniques with AYA, (2) selecting engagement platforms that complement survivors' information-seeking behavior, (3) improving outreach to survivors through appropriate branding and publicity, and (4) consolidating services from multiple providers. Conclusions: The design of survivorship care services for AYA survivors should be systematic in its conceptualization process and employ implementation strategies. The coordination of the wide spectrum of services warrants a concerted effort by cancer centers, community partners, and the government.

Cancer-related fatigue (CRF) is characterized by a lack of energy, and mitochondrial dysfunction is postulated to contribute to its etiology. This prospective cohort study assesses the self-reported fatigue levels of early-stage breast cancer patients using the validated Multi-Dimensional Fatigue Symptom Inventory-Short Form (MFSI-SF) and blood samples drawn at three time points: before treatment, approximately 6 weeks, and 12 weeks after the initiation of chemotherapy. The aim of this study is to evaluate mitochondrial measures with CRF, over the course of chemotherapy using mitochondrial DNA (mtDNA content) and displacement loop (D-loop) region sequence variations at nucleotide positions 303, 489 and 514. The relative mtDNA copy number was determined via real-time quantitative polymerase chain reaction and compared between study time points and D-loop sequence variants. The association of mtDNA content with MFSI-SF total and sub-domain scores was analyzed in a sample of 155 patients (mean age ± SD: 51.7 ± 8.8 years). The median mtDNA content decreased over 12 weeks after the initiation of chemotherapy (p 0.001). Baseline mtDNA content was lower for nucleotide position 303 in sequence variations than for the reference sequence (67.2 copies vs 79.1 copies, p = 0.03). Physical fatigue negatively correlated with mtDNA content in both unadjusted (β = -0.0075, p = 0.048) and adjusted models (β = -0.0062, p = 0.042), accounting for age, anxiety, insomnia, haemoglobin levels and body mass index. Our findings add to the literature indicating that mitochondrial function serves as an important target for mitigating CRF.

Adverse drug reactions (ADRs) contribute to hospitalization but data on its economic burden is scant. Pre-emptive pharmacogenetic (PGx) testing can potentially reduce ADRs and its associated costs. The objectives of this study were to quantify the economic burden of ADRs and to estimate the breakeven cost of pre-emptive PGx testing in Singapore. We collected itemized costs for 1000 random non-elective hospitalizations of adults admitted to a tertiary-care general hospital in Singapore. The presence of ADRs at admission and their clinical characteristics were reported previously. The economic burden of ADRs was assessed from two perspectives: (1) Total cost and (2) incremental costs. The breakeven cost of PGx testing was estimated by dividing avoidable hospitalization costs for ADRs due to selected drugs by the number of patients taking those drugs. The total cost of 81 admissions caused by ADRs was US$570,404. Costs were significantly higher for bleeding/elevated international normalized ratio (US$9906 vs. US$2251, p = 6.58 × 10-3) compared to other ADRs, and for drugs acting on the blood coagulation system (US$9884 vs. US$2229, p = 4.41 × 10-3) compared to other drug classes. There were higher incremental laboratory costs due to ADRs causing or being present at admission. The estimated breakeven cost of a pre-emptive PGx test for patients taking warfarin, clopidogrel, chemotherapeutic and neuropsychiatric drugs was US$114 per patient. These results suggest that future studies designed to directly measure the clinical and cost impact of a pre-emptive genotyping program will help inform clinical practice and health policy decisions.

OBJECTIVE To identify those experiencing significant self-reported cognitive decline over 2 time points during chemotherapy, examine the risk factors for cognitive decline, and examine differences between those with and without significant decline in functional limitations. METHODS This secondary analysis used data from 163 cancer patients, collected from a Korean University hospital. Significant decline was determined by 15% or more reduction from baseline in the Functional Assessment of Cancer Therapy-Cognitive Function. Multivariate logistic regression was performed to estimate risk factors. Repeated-measures ANOVA and t tests tested differences in groups with and without cognitive decline in cognitive impairment and functional limitation. RESULTS About 31% (n = 51) experienced significant cognitive decline. Groups with and without decline significantly differed in cognitive-impairment changes over time (F = 238.49, P

OBJECTIVES Currently, there are no studies that have established the self-perceived cognitive trajectories experienced by breast cancer patients (BCPs) post-chemotherapy. Therefore, we characterized the long-term trajectory of self-perceived cognitive function among Asian early-stage BCPs using the minimal clinically important difference of a subjective measure of cognitive function. METHODS Early-stage BCPs who received chemotherapy were recruited and assessed at 4 time points: Before chemotherapy initiation (T1), 6 weeks post-chemotherapy initiation (T2), 12 weeks post-chemotherapy initiation (T3), and 15-months post-chemotherapy initiation (T4). All assessments were performed approximately within 2 weeks post-chemotherapy. Subjective and objective cognitive function were assessed using Functional Assessment of Cancer Therapy-Cognitive (version 3) and Headminder™. RESULTS A total of 166 BCPs were recruited, of whom 131 completed assessment at all time points. Using the minimal clinically important difference of Functional Assessment of Cancer Therapy-Cognitive, 5 distinct cognitive trajectories were established. Of the 131 patients, 70 (53.4%) did not report any clinically significant cognitive impairment. Twenty-one (16.0%) patients reported acute cognitive changes during chemotherapy (T2 and/or T3) but not at T4. Forty patients (30.5%) reported clinically significant cognitive impairment at T4, of whom 18 did not report any cognitive impairment at earlier time points. Fifteen (11.5%) patients reported persistent cognitive impairment throughout all time points, while 7 (5.3%) patients reported intermittent cognitive impairment at T2 and T4 but not at T3. CONCLUSION This is the first study to establish the existence of heterogeneous cognitive trajectories based on clinically significant thresholds of self-perceived cognitive impairment. The findings have important implications on the window for screening and management of post-chemotherapy cognitive impairment.

Background Currently, several fatigue measurement instruments are available to evaluate and measure cancer-related fatigue. Amongst them, Multidimensional Fatigue Syndrome Inventory-Short Form (MFSI-SF) is a self-reported instrument and a multidimensional scale that aims to capture the global, somatic, affective, cognitive and behavioural symptoms of fatigue. This study examines the psychometric properties and measurement equivalence of the English and Chinese versions of MFSI-SF in breast cancer and lymphoma patients in Singapore. Methods Patients were recruited from National Cancer Centre Singapore. Validity, reliability and responsiveness of MFSI-SF were evaluated in this study. Convergent validity was evaluated by correlating total and subscales of MFSI-SF to known related constructs in EORTC QLQ-C30. Known group validity was assessed based on patients’ cancer stage, pain, insomnia and depression symptoms. Reliability was evaluated by Cronbach’s α. Responsiveness analyses were performed with patients who have undergone at least one cycle of chemotherapy. Multiple regression was used to compare the total and subscale scores of MSFI-SF between the two language versions. Results Data from 246 (160 English and 86 Chinese version) breast cancer and lymphoma patients were included in the study. Moderate to high correlations were observed between correlated MFSI-SF subscales and EORTC QLQ-C30 domains (|r| = 0.524 to 0.774) except for a poor correlation (r = 0.394) observed between MFSI-SF vigour subscale and EORTC QLQ-C30 role functioning subscale. Total MFSI-SF scores could differentiate between patients with higher depression, pain and insomnia status. Internal consistency of MFSI-SF was also high (α = 0.749 to 0.944). Moderate correlation was observed between change in total MFSI-SF score and change in fatigue symptom scale score and global QoL score on EORTC QLQ-C30 (|r| = 0.478 and 0.404 respectively). Poor correlations were observed between change in scores of hypothesised subscales (|r| = 0.202 to 0.361) except for a moderate correlation between change in MFSI-SF emotional fatigue score and change in EORTC QLQ-C30 emotional functioning domain score. Measurement equivalence was established for all subscales and total MFSI-SF score except for the emotional and vigour subscales. Conclusions This study supports the use of MFSI-SF as a reasonably valid scale with good internal consistency for measuring fatigue levels in the Singapore cancer population.

Cancer-related cognitive impairment (CRCI) is a significant problem for patients receiving chemotherapy. While a growing amount of pre-clinical and clinical evidence suggests that inflammatory mechanisms underlie CRCI, no clinical studies have evaluated for associations between CRCI and changes in gene expression. Therefore, the purpose of this study was to evaluate for differentially expressed genes and perturbed inflammatory pathways across two independent samples of patients with cancer who did and did not report CRCI. The Attentional Function Index (AFI) was the self-report measure used to assess CRCI. AFI scores of5 and of7.5 indicate low versus high levels of cognitive function, respectively. Of the 185 patients in Sample 1, 49.2% had an AFI score of5 and 50.8% had an AFI score of7.5. Of the 158 patients in Sample 2, 50.6% had an AFI score of5 and 49.4% had an AFI score of7.5. Data from 182 patients in Sample 1 were analyzed using RNA-seq. Data from 158 patients in Sample 2 were analyzed using microarray. Twelve KEGG signaling pathways were significantly perturbed between the AFI groups, five of which were signaling pathways related to inflammatory mechanisms (e.g., cytokine-cytokine receptor interaction, tumor necrosis factor signaling). This study is the first to describe perturbations in inflammatory pathways associated with CRCI. Findings highlight the role of cytokines both in terms of cytokine-specific pathways, as well as pathways involved in cytokine production and cytokine activation. These findings have the potential to identify new targets for therapeutics and lead to the development of interventions to improve cognition in patients with cancer.

203 Background: Cancer patients and survivors encounter a myriad of complex medical decisions starting from their diagnosis of cancer. However, current decision aids (DAs) largely focused on acute treatment and fertility decisions, and not on health service-related decisions such as adoption of supportive care services and programs targeting risk factor modification. This systematic review aims to identify and describe DAs supporting health service-related decisions after the completion of primary treatment until the end of life. Secondary objectives included assessing the effectiveness of these DAs and outlining implementation barriers. Methods: Electronic databases (PubMed and EMBASE) were searched comprehensively for relevant publications in English from inception through April 2020. Additional manual searches were performed on Google Scholar and from reference lists. We included studies that described the purpose and usage of DAs related to health services among cancer survivors 6 months post-diagnosis, after the typical acute treatment phase. Depending on the study design, included studies were assessed for quality using the Cochrane Collaboration’s tool and Critical Appraisal Skills Programme qualitative checklist. Results: Of 896 records screened, 11 studies describing seven DAs met the inclusion criteria. Non-interventional studies were generally of good quality, whereas most (4/6) interventional trials had a high risk of detection bias from failure to blind outcome assessors. DAs described were purposed for the creation of advanced directives, substance use behavior, preference for post-treatment follow-up care schedule, and health insurance were identified. All DAs adopted a multimedia format. DAs were generally acceptable and were associated with higher knowledge and satisfaction among users. No significant effects were observed for decision-making related outcomes, including decisional conflict and self-efficacy. Implementation barriers included time constraints, poor health statuses, limited perceived DA’s usefulness, and inadequate navigational support. Conclusions: The seven DAs identified addressed a diverse range of survivorship issues. Building on preliminary results reporting favorable acceptability, satisfaction, and knowledge, future work should explore the development and utility of DAs as facilitators to quality cancer survivorship care delivery, expanding into areas such as health promotion and choice of survivorship follow-up care models.

37 Background: Accessible Cancer Care to Enable Support for Cancer Survivors (ACCESS) is a multidisciplinary survivorship care model launched at the National Cancer Centre Singapore (NCCS) in 2019. ACCESS employs routine distress and problem screening to triage cancer patients with varying care needs and complexities for tailored care. Here, we described the study design to evaluate ACCESS, and reported the baseline characteristics of our study cohort to characterize the profile of prospective target recipients of the new care model. Methods: A cluster randomized controlled trial was initiated to assess the effectiveness of ACCESS on quality of life and symptom burden, with each cluster unit defined at the oncologist level. Clusters were randomized in a 1:1 ratio to receive ACCESS or usual care. Eligible patients were ≥21 years, newly diagnosed with breast or gynecological cancer, and receiving follow-up care in NCCS. Patients were followed up for one year and patient-reported outcomes were collected every three months using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and Rotterdam Symptom Checklist. Results: By May 2021, 91 patients and 89 patients in the usual care and ACCESS arm were recruited, respectively. Both groups (usual care vs. ACCESS) had comparable mean age (56.2±10.9 vs. 56.2±10.7, P = 0.998) and racial composition (P = 0.760). Employment status was similar in both arms (48.4% vs. 56.2% employed, P = 0.293) and most patients were covered by health insurance (89.8% vs. 88.1%, P = 0.920). At baseline, patients in both arms had comparable mean quality of life scores (65.1±19.8 vs. 66.9±17.6, P = 0.51) and reported high physical, role, emotional, cognitive, and social functioning levels (all mean scores > 70). No statistically significant differences in physical symptom and psychological distress levels were observed. Prevalent symptoms reported included fatigue (82.4% vs. 71.9%), pain (68.1% vs. 55.1%), and insomnia (57.1% vs. 55.1%). Almost half of the cohort reported financial difficulties (45.1% vs. 46.1%). Conclusions: Comparable baseline characteristics suggested the absence of systematic differences in care needs and demand among patients cared by different oncologists. Despite high functioning statuses at baseline, participants reported impaired quality of life with active physical and financial problems. These results support our hypothesis that routine screening would be valuable to identify such problems promptly for management via standardized care pathways. Results from this ongoing trial will determine the effectiveness of ACCESS on quality of life and functional recovery through treatment and survivorship. Clinical trial information: NCT04014309.

138 Background: Childhood cancer survivors (CCS) are often impacted by cancer-related cognitive impairment (CRCI), requiring long-term follow-up care. It is unknown whether survivors reporting CRCI are at higher likelihood to suffer from adverse lifestyle behaviors such as smoking and vaping. Using the Project Forward cohort, we analyzed the prevalence of CRCI and its association with substance abuse. Methods: The Project Forward study surveyed adolescent and young adult CCS between 2015 to 2018 to evaluate the quality of cancer follow-up care. Associations between self-reported CRCI and adverse lifestyle behaviors were examined in multivariable logistic regressions, adjusting for covariates: cancer type, treatment intensity, race/ethnicity, gender, and age at diagnosis. Stratified analysis by recency of latest cancer follow-up care was performed to examine its impact on the risk of substance abuse among CRCI patients. Results: The cohort comprised 1,106 CCS, with median ages of 25.5 years (IQR: 22, 29) at survey completion and 13 years (IQR: 7, 16) at diagnosis, with over half (n = 570, 51.5%) were being Hispanic. A total of 144 (13%) patients self-reported CRCI, with the highest prevalence observed among brain cancer (25.4%) and leukemia (13.3%) survivors. Cancer-related follow-ups were more frequently observed among survivors reporting CRCI, comparing to non-CRCI survivors (66.7% vs 56.9%, p = 0.030). After adjusting for confounders, survivors reporting CRCI were at higher odds to vape with e-cigarettes than those without CRCI (OR = 2.24, 95% CI = 1.24–4.09, p = 0.008). Among those who did not engage any recent cancer follow-up care (n = 455), CRCI was associated with 2.9 times the odds of vaping with e-cigarettes (OR = 2.9, 95% CI = 1.07–7.88, p = 0.037). No association was observed between CRCI and the use of cigarettes, alcohol, or marijuana. Conclusions: Vaping is more prevalent among CCS reporting CRCI, especially those who are less likely to attend follow-up care. Our data suggests the importance of encouraging long-term follow-ups to monitor adverse lifestyle behaviors in CCS experiencing cognitive symptoms and provide timely interventions.

Recently updated American Society of Clinical Oncology (ASCO) guidelines for Prevention and Management of Chemotherapy-Induced Peripheral Neuropathy (CIPN) in Survivors of Adult Cancers make a single recommendation to alter treatment by delaying, decreasing, or discontinuing dosing in patients who develop CIPN during neurotoxic chemotherapy treatment. Dosing guidelines have inconsistent recommendations for when (i.e., what CIPN severity) and how (i.e., delay, decrease, or discontinue) to alter neurotoxic chemotherapy treatment in patients with CIPN. Clinical decision making requires an understanding the benefits and risks of treatment alteration, in addition to consideration of other disease and patient factors. This review summarizes four areas of literature and culminates in a patient-centric decision framework to guide clinicians in helping patients to make treatment alteration decisions. First, we describe the current practice of altering treatment due to CIPN, including treatment alteration recommendations and published rates. Second, we summarize the potential benefits of treatment alteration including the reduction in CIPN severity and persistence. Third, we evaluate the potential risk of treatment alteration in compromising treatment efficacy by reviewing prospective trials comparing dosing regimens and retrospective analyses of the effect of relative dose intensity on efficacy. Fourth, we summarize disease and patient factors that should be considered when making a treatment alteration decision for a patient. We then propose a patient-centric decision framework that clinicians can use to assess an individual patient's current and anticipated future CIPN severity and compare that to their maximum tolerable severity to determine whether they should continue, delay, decrease, or discontinue neurotoxic chemotherapy.

With the long-term goal of optimising the delivery of breast cancer survivorship care in Singapore, we conducted a qualitative study to gather in-depth descriptions from community practitioners (general practitioners and community pharmacists) about their perceptions of community-based cancer survivorship care in Singapore. Sixteen participants (11 general practitioners and five community pharmacists) participated in four structured focus group discussions between August and November 2016. The focus group discussions were analysed using deductive content analysis. The majority of community practitioners do not encounter breast cancer survivors in their clinical practices. Perceived barriers to community-based survivorship care include patients' lack of confidence in primary care, financial constraints and lack of empanelment. Most community practitioners concur that the success of community-based survivorship care largely depends on the co-operation and participation of survivors. Survivorship management via standardised care pathways is not fully advocated by practitioners. Survivorship care plans are identified as useful, but they should also incorporate a non-cancer-related medical history and medication list. Community practitioners in Singapore are eager to participate in the delivery of cancer survivorship care. Future studies should develop a community-based care model that involves community practitioners and evaluate the cost-effectiveness of such a care model. The current model of cancer survivorship in Singapore is not sustainable. Differences in healthcare ecosystems, cultures and resources available in an Asian context should be taken into consideration before designing a community-based cancer survivorship program in Singapore.

A meeting of regional experts was convened in Manila, Philippines, to develop a resource-stratified chemotherapy-induced nausea and vomiting (CINV) management guideline. In patients treated with highly emetogenic chemotherapy in general clinical settings, triple therapy with a serotonin (5-hydroxytryptamine-3 [5-HT3]) antagonist (preferably palonosetron), dexamethasone, and aprepitant is recommended for acute CINV prevention. In resource-restricted settings, triple therapy is still recommended, although a 5-HT3 antagonist other than palonosetron may be used. In both general and resource-restricted settings, dual therapy with dexamethasone (days 2 to 4) and aprepitant (days 2 to 3) is recommended to prevent delayed CINV. In patients treated with moderately emetogenic chemotherapy, dual therapy with a 5-HT3 antagonist, preferably palonosetron, and dexamethasone is recommended for acute CINV prevention in general settings; any 5-HT3 antagonist can be combined with dexamethasone in resource-restricted environments. In general settings, for the prevention of delayed CINV associated with moderately emetogenic chemotherapy, corticosteroid monotherapy on days 2 and 3 is recommended. If aprepitant is used on day 1, it should be continued on days 2 and 3. Prevention of delayed CINV with corticosteroids is preferred in resource-restricted settings. The expert panel also developed CINV management guidelines for anthracycline plus cyclophosphamide combination schedules, multiday cisplatin, and chemotherapy with low or minimal emetogenic potential, and its recommendations are detailed in this review. Overall, these regional guidelines provide definitive guidance for CINV management in general and resource-restricted settings. These consensus recommendations are anticipated to contribute to collaborative efforts to improve CINV management in Southeast Asia.

Purpose Few studies have determined the benefits of pharmacist-run clinics within a tertiary institution, and specifically on their capability to improve clinical outcomes as well as reduce the cost of illness. This study was designed to investigate the effectiveness of a pharmacist-managed risk factor management clinic (RFMP) in an acute care setting through the comparison of clinical (improvement in glycosylated hemoglobin level) and cost outcomes with patients receiving usual care. Methods This single-center, observational study included patients aged ≥21 years old and diagnosed with type 2 diabetes mellitus (DM) who received care within the cardiology department of a tertiary institution between January 1, 2014, and December 31, 2015. The intervention group comprised patients who attended the RFMP for 3 to 6 months, and the usual-care group comprised patients who received standard cardiologist care. Univariate analysis and multiple linear regression were conducted to analyze the clinical and cost outcomes. Findings A total of 142 patients with DM (71 patients in the intervention group and 71 patients in the usual-care group) with similar baseline characteristics were included. After adjusting for differences in baseline systolic blood pressure and triglyceride levels, the mean reduction in glycosylated hemoglobin level at 6 months from baseline in the intervention group was significantly lower by 0.78% compared with the usual-care group. Patients in the usual-care group had a significantly higher risk of hospital admissions within the 12 months from baseline compared with the intervention group (odds ratio, 3.84 [95% CI, 1.17–12.57]; P = 0.026). Significantly lower mean annual direct medical costs were also observed in the intervention group (US $8667.03 [$17,416.20] vs US $56,665.02 [$127,250.10]; P = 0.001). Implications The pharmacist-managed RFMP exhibited improved clinical outcomes and reduced health care costs compared with usual care within a tertiary institute.

Objective The primary objective of this study is to prospectively evaluate the role of procalcitonin (PCT) in distinguishing infectious fever from noninfectious fever (NIF) among febrile lymphoma patients. The secondary objective is to evaluate the usefulness of PCT in distinguishing among bloodstream infections (BSI), local infections and unidentified infections (LIUI), and NIF. Methods Patients with lymphoma and fever were prospectively recruited between August 2014 and November 2015. PCT was measured within 24 hours of fever onset (PCT1) and 24-72 hours thereafter (PCT2). The higher PCT value between PCT1 and PCT2 was also documented (PCTmax ). PCT levels (PCT1, PCT2, and PCTmax ) were compared for BSI, LIUI, and NIF. In addition, the difference between PCT1 and PCT2 was evaluated in patients with complete data on both PCT1 and PCT2. Results Of 108 eligible patients, 12 were diagnosed with BSI, 83 with LIUI, and 13 with NIF. PCTmax was statistically different between the infectious fever (BSI and LIUI combined) and NIF groups (median PCTmax : 0.44 ng/ml vs 0.19 ng/ml; p=0.026). PCT1 was not statistically different for patients with BSI, LIUI, and NIF (p=0.217). However, PCT2 and PCTmax were significantly higher in patients with BSI compared to those with NIF (p=0.026 and 0.002, respectively). Meanwhile, patients with BSI have significantly higher PCTmax values than those with LIUI (p=0.034). Among 90 cases with complete data on both PCT1 and PCT2, PCT2 was significantly higher than PCT1 in patients with BSI (median PCT: 0.98 ng/ml vs 0.47 ng/ml; p=0.045) and patients with LIUI (median PCT: 0.43 ng/ml vs 0.24 ng/ml; p=0.004), while not significant in patients with NIF (p=0.374). Conclusion Two separate PCT measurements can differentiate between infectious fever and NIF and predict for BSI in lymphoma patients with fever.

Background As cancer mortality rates improve in Singapore, there is an increasing need to improve the transition to posttreatment survivorship care. This study aimed to evaluate the effectiveness of a psychoeducation group (PEG) intervention program compared with usual care to reduce distress for physical symptom and psychological aspects in Asian breast cancer survivors who have completed adjuvant chemotherapy. Methods This was a randomized, controlled trial comprising 72 Asian early stage breast cancer survivors who were randomized into the PEG (n = 34) or the control (n = 38) arm. The participants in the PEG arm underwent a weekly multidisciplinary PEG program delivered in a group format over 3 weeks coupled with cultural adaptation. Both arms were assessed at baseline and 2 months after intervention using the Rotterdam Symptom Checklist, Beck Anxiety Inventory, and EORTC QLQ-C30. A satisfaction questionnaire was also conducted among those survivors who have participated in the PEG program. Effective sizes were calculated using Cohen d. Results The mean age ± SD of all participants was 53.0 ± 8.9 years, with the majority being Chinese (84.7%) and Malay (6.9%), and clinical characteristics were well balanced in both arms. Compared to the control arm, the PEG arm showed a significantly greater reduction in physical symptom distress (d = 0.76, P = .01) and fatigue (d = 0.49, P = .04). The 82.4% of the participants in the intervention group responded to the satisfaction questionnaire, and the majority (92.9%) agreed that the overall duration of the PEG intervention program was appropriate. Conclusions A culturally adapted PEG program was effective in reducing physical symptom distress in Asian breast cancer survivors. (ClinicalTrials.gov: NCT02600299)
