The present study examined the relationships between CT-derived muscle measurements, systemic inflammation, and survival in advanced cancer patients with good performance status (ECOG-PS 0/1). Data was collected prospectively from patients with advanced cancer undergoing anti-cancer therapy with palliative intent. The CT Sarcopenia score (CT-SS) was calculated by combining the CT-derived skeletal muscle index (SMI) and density (SMD). The systemic inflammatory status was determined using the modified Glasgow Prognostic Score (mGPS). The primary outcome of interest was overall survival (OS). Univariate and multivariate Cox regressions were used for survival analysis. Three hundred and seven patients met the inclusion criteria, out of which 62% (n = 109) were male and 47% (n = 144) were ≥65 years of age, while 38% (n = 118) were CT-SS ≥ 1 and 47% (n = 112) of patients with pre-study blood were inflamed (mGPS ≥ 1). The median survival from entry to the study was 11.1 months (1–68.1). On univariate analysis, cancer type (p < 0.05) and mGPS (p < 0.001) were significantly associated with OS. On multivariate analysis, only mGPS (p < 0.001) remained significantly associated with OS. In patients who were ECOG-PS 0, mGPS was significantly associated with CT-SS (p < 0.05). mGPS may dominate the prognostic value of CT-derived sarcopenia in good-performance-status patients with advanced cancer.

Purpose Expanded access programs (EAPs) allow patients with cancer who have unmet clinical needs to obtain access to pre-authorisation treatments. There is no standardised process or registry for implementing these programs nationally and real world data on their impact is lacking. We evaluated their prevalence and impact in a cancer centre.Methods Data relating to adult cancer patients treated via EAPs from 2011 to 2021 in three Cork university hospitals was collated. Descriptive statistics were employed to get an overview of the impact these programs currently have on cancer care provision.Results We identified 193 patients who accessed EAPs during the study period, availing of 33 separate drugs for a total of 50 different cancer indications. The prevalence of EAP usage was shown to have been trending upwards in recent years with a total of 189 programs being accessed throughout the period. Drugs provided were from a number of different anti-cancer drug classes, particularly targeted therapies (n = 18) and immune checkpoint inhibitors (n = 17). Cancers from a wide range of both solid and liquid tumour types were identified as having been treated with EAP drugs and patients treated were from across a broad spectrum of ages (26–82, SD:11.99).Conclusion EAPs have an increasing role in access to novel cancer therapies in our community and by extension nationally. Equity of EAP access would be facilitated by a national registry of available agents which we have now established. Assessment of their benefits and toxicities would be enhanced by the requirement for a real world data base as a condition of EAP approval.

Aim: Adjuvant chemotherapy in NSCLC is associated with modest benefits and significant toxicity. We sought to evaluate the toxicity of adjuvant chemotherapy and disease-specific outcomes in a real-world population. Methods: We performed a retrospective analysis of patients undergoing adjuvant chemotherapy for NSCLC in an Irish center over a 7-year period. We described treatment-associated toxicity, recurrence-free survival and overall survival. Results: 62 patients underwent adjuvant chemotherapy. Treatment-associated hospitalisation occurred in 29% of patients. Relapse was recorded in 56% of patients and median recurrence-free survival was 27 months. Conclusion: High rates of disease recurrence and treatment-associated morbidity were observed in patients receiving adjuvant chemotherapy for NSCLC. Novel therapeutic strategies are required to improve outcomes in this population.

Improvements in early detection, screening and treatment of cancer have resulted in a significant improvement in cancer mortality and an increase in the number of cancer survivors globally. Accordingly, a significant rise in the number of cancer survivors in Ireland has been observed. The surveillance of survivors of gastrointestinal malignancies in Ireland is heterogeneous and represents an unmet need for standardisation.There are currently no national guidelines in Ireland to guide follow-up practices for these patients. The aim of this study was to establish homogeneity nationally with respect to follow-up of these patients by medical oncologists.A consensus group consisting of Irish oncologists with an interest in gastrointestinal malignancies was created to address this issue, and determined that it would be reasonable to adopt the NCCN guidelines for this purpose, but that this recommendation would not be prescriptive, and should be individualised to each patient.We hope that this initiative may help to homogenise survivorship practices in this cohort of Irish patients, and may support the implementation of survivorship initiatives by the National Cancer Control Programme (NCCP).

Contains fulltext : 251996.pdf (Publisher’s version ) (Open Access) We report an autosomal recessive, multi-organ tumor predisposition syndrome, caused by bi-allelic loss-of-function germline variants in the base excision repair (BER) gene MBD4. We identified five individuals with bi-allelic MBD4 variants within four families and these individuals had a personal and/or family history of adenomatous colorectal polyposis, acute myeloid leukemia, and uveal melanoma. MBD4 encodes a glycosylase involved in repair of G:T mismatches resulting from deamination of 5'-methylcytosine. The colorectal adenomas from MBD4-deficient individuals showed a mutator phenotype attributable to mutational signature SBS1, consistent with the function of MBD4. MBD4-deficient polyps harbored somatic mutations in similar driver genes to sporadic colorectal tumors, although AMER1 mutations were more common and KRAS mutations less frequent. Our findings expand the role of BER deficiencies in tumor predisposition. Inclusion of MBD4 in genetic testing for polyposis and multi-tumor phenotypes is warranted to improve disease management.

Background Advanced colorectal cancer (CRC) is frequently a lethal disease. Mutations in the BRAF gene is a key driver in CRC pathogenesis and confers a poor prognosis. To date, Irish data on this molecular subtype of CRC is lacking. Aims Our aim was to compare the natural history of Irish patients with BRAF (BRAFMUT) metastatic CRC with a control group of metastatic CRC patients without BRAF mutation (BRAFWT wild- type). Method A retrospective observational analysis of advanced CRC patients with known BRAFMUT was conducted by chart review. BRAFMUT patients were identified from the Cork University Hospital (CUH) histopathology database. Controls with known BRAFWT were randomly selected from the database. Demographic characteristics and clinicopathological data were recorded. Survival was assessed with Kaplan–Meier curve/Cox proportional hazard models. Results Twenty patients with BRAFMUT and 36 with BRAFWT were studied. BRAFMUT were more likely female (75% vs 33%, p = 0.007) and right-sided (65% vs 31.4%, p = 0.033). Median overall survival was lower in BRAFMUT group (17.3 months (95% CI 0–40.8)) compared to patients with BRAFWT (median survival not reached, log rank p = 0.001). On multivariate analysis, BRAFMUT was independently associated with an increased risk of mortality (HR 12.76 (95% CI 3.15–51.7), p Conclusion BRAFMUT advanced colorectal cancer was associated with significantly reduced overall survival in this Irish CRC population. Knowledge of mutation status should now be considered standard of care and should dictate management. Surgeons should be aware of this genetic signature as the natural history of the disease may mitigate against an aggressive surgical strategy. A prospective study should be conducted to further corroborate these findings.

Background Although suggestive of dysregulated metabolism, the relationship between serum LDH level, phenotypic/aetiologic diagnostic Global Leadership Initiative on Malnutrition (GLIM) criteria and survival in patients with advanced cancer has yet to examined. Methods Prospectively collected data from patients with advanced cancer, undergoing anti-cancer therapy with palliative intent, across nine sites in the UK and Ireland between 2011–2016, was retrospectively analysed. LDH values were grouped as 500 Units/L. Relationships were examined using χ2 test for linear-by-linear association and binary logistics regression analysis. Results A total of 436 patients met the inclusion criteria. 46% (n = 200) were male and 59% (n = 259) were ≥65 years of age. The median serum LDH was 394 Units/L and 33.5% (n = 146) had an LDH > 500 Units/L. LDH was significantly associated with ECOG-PS (p p p p p p p p p p Discussion LDH was associated with performance status, systemic inflammation and survival in patients with advanced cancer. LDH measurement may be considered as an aetiologic criteria and become a potential therapeutic target in the treatment of cancer cachexia.

A 66-year-old woman receiving pembrolizumab for metastatic melanoma presented with tender red nodules on her shins and forearms. Biopsy was consistent with erythema nodosum (EN). The eruption responded to oral minocycline and potent topical steroids. Subsequent investigations detected bihilar lymphadenopathy, biopsied as granulomatous lymphadenitis, confirming the diagnosis of pembrolizumab-associated sarcoidosis. Pembrolizumab was stopped for two cycles and was restarted without recrudescence of EN or bihilar lymphadenopathy. Immunotherapy-associated sarcoidosis is a rare but recognized adverse event related to therapy with immune checkpoint inhibitors. EN is an uncommon manifestation of immunotherapy-induced sarcoidosis. New-onset bihilar lymphadenopathy in the context of immunotherapy requires prompt histological evaluation to differentiate between immunotherapy-associated sarcoidosis and metastatic progression. We review the literature related to immunotherapy-associated EN.Pembrolizumab (trade name Keytruda

Spontaneous regression is defined as the partial or complete resolution of a malignant neoplasm either with treatment that is perceived to be inadequate or in the absence of therapy. This report describes a case of spontaneous regression of a pulmonary metastasis of renal cell carcinoma secondary to metastasectomy in the contralateral lung.

Summary Background Attitudes of cancer survivors to nutrition and nutrition care have rarely been captured. A better understanding of their needs based on a review of their experiences would give voice to this patient group (which has rarely been captured) and allow for better planning of nutritional care. Aims To conduct a national survey to determine: (1) survivors' experience in relation to nutrition and diet-related problems, (2) perceived importance of the role of nutrition to cancer survivors, (3) the experience of accessing dietetic support, (4) the sources where survivors get nutrition information, and (5) their use of alternative dietary strategies. Methods Survivors (any adult ever diagnosed with cancer) who had been diagnosed with or treated for cancer in Ireland within the past 5 years, were asked to complete a 25-item paper-based survey at one of 20 different hospital sites in Ireland. The survey was also hosted online on the websites of major cancer charities. Descriptive statistics were used to examine quantitative data. Results In total, 1073 valid responses were received (63% female, mean age 57 years (range 18–88)). Breast cancer was the most common (n = 362), followed by colorectal (n = 121). One third of respondents had metastatic disease. Diet-related problems were reported by 45%. Weight loss was experienced by 44% and amongst those, 42% reported they were ‘unhappy or worried’ by this, while 27% reportedbeing ‘delighted/happy’ with their weight loss. Muscle loss was noted by 52%, with 20% reporting they had noticed ‘a lot’ of muscle loss. Nutrition was rated as ‘very/extremely’ important to cancer care by 89% of respondents, yet 58% reported being asked about dietary issues by their medical team only ‘sometimes’, ‘rarely’ or ‘never’. Only 39% had been assessed/treated by a registered dietitian (RD) and 74% rated their advice/care as ‘very/extremely’ helpful. Worryingly, 39% of survivors with involuntary weight loss, and 29% of survivors on a texture modified diet had not received nutritional care from an RD. Overall, 57% of those who did not see an RD said they wanted more dietetic support (access to a helpline/dietitian/additional reliable information). Of concern, 37% of survivors were following or had tried alternative, unproven dietary strategies (e.g. restrictive diets, herbal remedies, juicing or detoxes), and 32% reported avoiding specific foods, e.g. processed meat or dairy. A majority (56%) felt confused by the often conflicting nutrition information available in the media and offered by people around them. Conclusions While nutrition is considered highly important by cancer survivors and a high proportion experience potentially serious diet-related problems including weight and muscle loss, fewer than half surveyed had access to a dietitian. Over a third had used at least one alternative dietary strategy, and over half felt confused about nutrition. Comprehensive nutritional screening and referral programmes to oncology dietitians need to be implemented in the ambulatory setting in order to identify and facilitate early management of the nutritional concerns of cancer survivors.

Background Weight loss (WL) and sarcopenia are associated with negative oncological outcomes including poor treatment tolerance, decreased quality of life, and reduced survival. The number of patients affected by sarcopenia and WL in Ireland and the UK is unknown. Methods A systematic review was undertaken to determine median rate of WL > 5% and computed tomography‐diagnosed sarcopenia in oncology populations. Gaps in the literature were supplemented using local data, collected as part of a 5 year prospective study. Rates of WL and sarcopenia in the population were extrapolated from these data based on incidence and prevalence of each cancer as per national cancer registries. Results We estimated that across Ireland and the UK, 128 892 cancer patients (34%) are affected by WL > 5% annually (121 641 UK; 7251 Ireland) and there are 133 707 annual cases of sarcopenia in cancer patients (35%) (126 265 UK; 7442 Ireland). Furthermore, we estimate that there are 716 124 and 771 589 cancer survivors with history of WL > 5% or sarcopenia, respectively. Conclusions Large numbers of patients are affected by cancer‐related malnutrition. Given the impact of malnutrition on oncological outcomes and long‐term frailty, there is an urgent need to improve access to cancer nutrition care.

Background: Optimizing quality of life (QoL) remains the central tenet of care in patients with incurable cancer; however, determinants of QoL are not clear. The objective of the current study was to examine which factors influence QoL in patients with incurable cancer. Methods: A multicenter study of adult patients with advanced cancer was conducted in Ireland and the United Kingdom between 2011 and 2016. Data were collected from patients at study entry and included patient demographics, Eastern Cooperative Oncology Group performance status (ECOG‐PS), nutritional parameters (the percentage weight loss [%WL]), muscle parameters assessed using computed tomography images (skeletal muscle index and skeletal muscle attenuation), inflammatory markers (modified Glasgow Prognostic score [mGPS]), and QoL data (the European Organization for Research and Treatment Quality‐of‐Life Questionnaire C‐30). The relation between clinical, nutritional, and inflammatory parameters with QoL was assessed using the Spearman rank correlation coefficient and multivariate binary logistic regression. Components of the European Organization for Research and Treatment Quality‐of‐Life Questionnaire C‐30 (physical function, fatigue, and appetite loss) and summary QoL scores were mean‐dichotomized for the logistic regression analyses. Results: Data were available for 1027 patients (51% men; median age, 66 years). Gastrointestinal cancer was most prevalent (40%), followed by lung cancer (26%) and breast cancer (9%). Distant metastatic disease was present in 87% of patients. The %WL, ECOG‐PS, and mGPS were significantly correlated with deteriorating QoL functional and symptom scales (all P < .001). On multivariate regression analysis, >10% WL (odds ratio [OR], 2.69; 95% CI, 1.63‐4.42), an ECOG‐PS of 3 or 4 (OR, 14.33; 95% CI, 6.76‐30.37), and an mGPS of 2 (OR, 1.58; 95% CI, 1.09‐2.29) were independently associated with poorer summary QoL scores. These parameters were also independently associated with poorer physical function, fatigue, and appetite loss (all P < .05). Low skeletal muscle attenuation was independently associated with poorer physical functioning (OR, 1.67; 95% CI, 1.09‐2.56), but muscle parameters were not independently associated with fatigue, appetite loss, or QoL summary scores. Conclusions: The current findings indicate that QoL is determined (at least in part) by WL, ECOG‐PS, and the systemic inflammatory response in patients with advanced cancer. Identifying early predictors of poor QoL may allow the identification of patients who may benefit from early referral to palliative and supportive care, which has been shown to improve QoL.

Background: Pembrolizumab is a monoclonal antibody targeting PD-1. Folliculitis secondary to pembrolizumab has rarely been reported in the treatment of malignant melanoma. Case: A 49-year-old with a history of mild lower limb folliculitis developed metastatic malignant melanoma, and immunotherapy with pembrolizumab was initiated. Following 19 doses of pembrolizumab, a folliculocentric pustular eruption developed on the lower legs. Biopsy was consistent with folliculitis. Treatment with topical corticosteroids, high-dose prednisolone, lymecycline, clarithromycin, trimethoprim and clindamycin was unsuccessful. Pembrolizumab was stopped after 22 cycles, but the folliculitis persisted. Oral isotretinoin was required for disease control. Discussion: Drug-induced follicular eruptions have rarely been described with anti PD-1 therapy. Isotretinoin may be required to achieve remission. Lay abstract: Pembrolizumab (trade name Keytruda©) is a type of immune therapy that stimulates the body's immune system to fight cancer cells. This immune therapy can cause a variety of rashes. In this article, the authors describe a patient who developed a rash around hair follicles that is not commonly described with pembrolizumab. A man with a history of mildly infected hair follicles on his legs was diagnosed with advanced melanoma and was treated with pembrolizumab. After 19 treatments, he developed a rash on his legs, centered around hair follicles. Treatment with steroid ointments, steroid tablets and antibiotic tablets was not helpful. Pembrolizumab was stopped, but the rash persisted. A medicine called isotretinoin was required to control the rash. This type of rash has rarely been described with this kind of immune therapy, and isotretinoin might be required to treat it.

There are disparities in the availability of systemic anticancer therapies (SACTs) globally. We set out to investigate the cost and reimbursement of SACTs in the United Kingdom (UK) and the Republic of Ireland (ROI) in conjunction with efficacy and licensing authority decisions in the United States (US) and the European Union (EU).We sought data pertaining to licensing in the EU, reimbursement in ROI/UK and cost/efficacy of SACTs licensed by the Food and Drug Administration (FDA) between January 2015 and May 2021. Independent samples t tests, chi-square test and Pearson's correlation were used for statistical analysis.We identified that the majority of FDA-approved regimens are licensed by the European Medicines Agency (EMA) (n = 91, 67.9%). However, only a minority of these are currently reimbursed in the UK (n = 60, 45%) or the ROI (n = 28, 21%) as of the 1Our study highlights that many licensed systemic anticancer treatments are not currently reimbursed in ROI/UK. The high cost of these medicines is independent of the presence of an OS benefit. Collaboration between regulatory agencies, governments and industry partners is needed to ensure health expenditure is directed towards the most effective treatments.

Current treatment strategies for advanced melanoma require serial assessment of disease status in affected patients. In this study, we sought to examine the relationship between radiographic tumour burden and blood borne biomarkers including plasma cfDNA, serum LDH, plasma VEGF, PD-L1 and IFN-γ in advanced melanoma patients receiving immunotherapy. We hypothesized that a combination of these explanatory variables in a suitable regression analysis model may predict changes in tumour burden during patient treatment.We extracted and quantified circulating cfDNA, LDH, VEGF, PD-L1, and IFN-γ from thirty patients with stage IV melanoma at baseline and at six months. All participating patients were evaluated with paired blood sample collection and CT scan assessments during treatment.Changes in radiographic tumour burden correlated with changes in levels of cfDNA (p≤0.001), LDH (p≤0.001), VEGF (p≤0.001), and PD-L1 (p0.05) during treatment. Multiple regression analysis consisting of the follow-up to baseline assessment ratios of cfDNA, LDH, VEGF and PD-L1 explained changes in tumour burden (F (4, 23)=32.05, p0.001); with an RA quantitative measure of cfDNA, LDH, VEGF and PD-L1 may complement current methods of assessing tumour burden in advanced melanoma patients.

Introduction Serial monitoring for disease progression and therapeutic efficacy at the molecular level in metastatic melanoma is hampered by a lack of reliable blood borne biomarkers. Molecular profiling of melanoma tumours is almost impractical in metastatic disease due to risks of procedure related morbidity and sampling inefficiency in representing tumour heterogeneity. Cell free DNA allows monitoring of molecular changes in melanoma over the course of immunotherapy. We investigated the utility of somatic mutation and gene amplification analyses in melanoma patients receiving immunotherapy. Method Cell free DNA was extracted from plasma using a QIAamp Circulating Nucleic Acid Kit (Qiagen). Pathway focused profiling of somatic mutation status was performed by ARMs PCR using QBiomarker Somatic Mutation PCR Arrays (Qiagen). Gene amplification analysis was performed by Real Time Quantitative PCR (Roche) using RT2 Profiler PCR Arrays (Qiagen). Result A total of twenty patients with stage IV melanoma receiving immunotherapy were enrolled in this study. The BRAF p.V600E mutation was detected in the cfDNA of 80% of BRAF positive patients. Cell free DNA was also profiled for a total of 84 genes of the cancer inflammation and immunity pathway. There was a significant difference in the copy numbers of several genes (CTLA-4, CXCL12, CXCL5, IDO1, TGFB, IFNG, IL4, PTGS2, AICDA, HLA-A, CCL4, ACKR3, TP53, MYC) between patients with progressive disease and therapeutic response (n=20, p Conclusion We postulate that cell free DNA pathway focused somatic mutation and gene amplification analyses may be useful in evaluating disease progression and therapeutic response. Take-home message Genomic analysis of circulating nucleic acids may be useful in evaluating disease progression and therapeutic response in metastatic melanoma.

A 65-year-old female patient has a history of malignant triton tumour of the right upper lobe of the lung. She underwent right upper lobectomy and lymphadenectomy in May 2018. She presented in November 2019 with pathological fracture of the left proximal femur. It was not associated with neurofibromatosis. We decided to do an excisional biopsy of the mass and proximal femoral replacement followed by radiotherapy. Four months later, she presented with local recurrence. We organised a multidisciplinary team between the orthopaedic, histopathology and oncology teams. Then, we decided to treat her with chemotherapy. After 2 months of follow-up, she responded well to the chemotherapy with no further deterioration of her condition.

Background: In December 2019 a cluster of pneumonias, later identified as SARS-CoV-2 (CoV), were reported in China. The first case in Ireland was reported February 29th 2020. The first community acquired case in Ireland was reported March 5th. The World Health Organisation declared CoV a pandemic March 11th. Lockdown measures were implemented in Ireland March 27th. Cork University Hospital is a large acute hospital and a tertiary referral center for cancer care. We undertook an audit of unscheduled medical oncology admissions over a 3 month period with a view to assess the impact of CoV on the centre. Method(s): From 1st February to 30th April we audited unscheduled medical oncology admissions. Parameters included presenting time, location and complaint, CoV status and average length of hospital stay (aLOS). Data was organised into 3 phases: four week period prior to a confirmed case of CoV in Ireland (phase I), four week period from confirmed case to lockdown implementation (phase 2) and four week period during lockdown (phase 3). After the outbreak of CoV we developed a separate medical oncology assessment facility (AOS) with an admission pathway. A hospital CoV pathway (CoVp) for potential CoV cases was also implemented. Result(s): A total of 162 medical oncology patients had unscheduled admissions during this period. Over half (57%) were receiving anticancer systemic treatment. The most common presenting complaints were pain (21%), pyrexia (17%) and dyspnoea (14%). The underlying diagnosis was cancer-related in 51%, treatment-related toxicity in 10% and non-cancer related in 39%. One patient was CoV positive. Unscheduled hospital admissions, source of admission and aLOS are outlined in the Table. [Formula presented]. Conclusion(s): A reduction in aLOS and ED admissions was paralleled by increasing use of alternative pathways. Processes which facilitate urgent assessment of oncology patients in specialized units avoid ED attendance and accelerate discharge planning in the care of cancer patients in the face of a pandemic and beyond.

A 23-year-old male accountant with no comorbidities developed a cough and dyspnoea while travelling for work in the UK during March 2020. His symptoms developed over 2 weeks and having contacted a local primary care office, he was referred to a COVID-19 test centre. A swab was not performed as he

Introduction “Transgender” and “gender diverse” are umbrella terms encompassing those whose gender identities or expressions differ from those typically associated with the sex they were assigned at birth. There is scant global information on cancer incidence, outcome, and mortality for this cohort. This group may present with advanced cancer, have mistrust in health care services and report anxiety and depression at higher frequencies, a finding often seen in marginalized groups because of minority stress. Materials and Methods Medical oncologists were contacted by secure email to identify patients who self-identify as transgender and gender diverse in three Irish hospitals. Five patients were identified. A retrospective chart review was conducted and a pseudonymized patient survey was distributed. Results All patients included in our chart review (n = 5) were diagnosed with advanced disease on initial diagnosis. Two patients identified as men, two as women, and one as a transwoman. Two of five patients' health record charts reflected a name or gender change. Three patients had gender transitioning treatment postponed. Assessing comorbidities, it was seen that four patients required psychiatry input. Predominant issues noted in our patient survey by the two respondents (n = 2) were “mis-gendering,” lack of a gender-neutral hospital environment, lack of inclusion in cancer groups, and barriers in changing name and/or sex on hospital records. Conclusion Components of care requiring revision include patient accessible pathways to change names and gender on health records, earlier access to psychological support and targeted screening and support groups. Resources for hospital staff to improve awareness of correct terminology and to provide gender neutral facilities are worthwhile. Implications for Practice The implications for practice on an international level include patient-friendly pathways for changing hospital name and gender so that patients may feel comfortable using wristbands. The need for international screening guidelines for transgender patients and national transgender cancer support groups is highlighted. On a day-to-day level for providers, the correct use of pronouns makes a big difference to patients. Asking about preferred pronoun on first visit and noting on patient's file is worthwhile. It is important for providers to know that increased psychological support should be offered early on first clinic visit and engaged with as necessary when patient has a history of anxiety or depression. Providers should discuss openly that some gender transitioning treatment will be postponed because of cancer care and refer to both the physical and psychological sequelae of this. Asking transgender patients which room or bathroom they would prefer when rooms are gendered is essential.

Cancer remains one of the leading causes of mortality worldwide and the associated reduction in physical function has a marked impact on both quality of life and survival. The aim of the present study was to examine the relationship between Eastern Cooperative Oncology Group-Performance status (ECOG-PS), modified Glasgow Prognostic Score (mGPS), Body Mass Index/ Weight Loss grade (BMI/WL grade), and Computerised Tomography (CT)-derived body composition measurement and physical function in patients with advanced cancer. Nine sites contributed prospective data on patient demographics, ECOG-PS, mGPS, physical function tests, and CT-derived body composition. Categorical variables were analysed using &chi, 2 test for linear-by-linear association, or &chi, 2 test for 2-by-2 tables. Associations were analysed using binary logistic regression. A total of 523 cancer patients (266 males, 257 females) were included in the final analysis and most had metastatic disease (83.2%). The median overall survival was 5.6 months. On multivariate binary logistic regression analysis, a high ECOG-PS remained independently associated with a low skeletal muscle index (p &lt, 0.001), low skeletal muscle density (p &lt, 0.05), and timed up and go test failure (p &lt, 0.001). A high mGPS remained independently associated with a low skeletal muscle density (p &lt, 0.05) and hand grip strength test failure (p &lt, 0.01). A high BMI/WL grade remained independently associated with a low subcutaneous fat index (p &lt, 0.05), low visceral obesity (p &lt, 0.01), and low skeletal muscle density (p &lt, 0.05). In conclusion, a high ECOG-PS and a high mGPS as outlined in the ECOG-PS/mGPS framework were consistently associated with poorer body composition and physical function in patients with advanced cancer.

Obesity is an established risk factor for colorectal cancer (CRC), however little is known about changes in body composition during chemotherapy and its impact on survival. The aim of this study was to examine in patients with CRC: (1) The prevalence of abnormal body composition phenotypes, (2) The impact of baseline body composition on overall survival, (3) Changes in body composition throughout treatment and its impact on overall survival.A prospective study of adult CRC patients undergoing chemotherapy between 2012–2016 was conducted. Longitudinal changes in body composition were examined using computed tomography (CT) images at two timepoints (interval 7 months, IQR: 5–9 months) using paired t-tests. Sarcopenia and low muscle attenuation (MA) were defined using published cut-offs. Cox proportional-hazards models were used to estimate mortality hazard ratios, adjusted for known prognostic covariates – stage, age, sex, performance status & systemic inflammation.In total, 268 patients were recruited (66% male, mean age 63 years) and 51% were undergoing chemotherapy with a palliative intent. At baseline, 4% were underweight (BMI < 20 kg/m2), 38% had a normal BMI, and 58% were overweight/obese. Despite this, 38% had cancer cachexia, 34% were sarcopenic and 43% had low MA. Neither sarcopenia, sarcopenic obesity nor cachexia at baseline predicted survival. Over 100 days, 68% were muscle stable (± 1 kg), while 25% lost > 1 kg and 7% gained > 1 kg. Fat mass remained stable ± 1 kg in 49%, while 28% lost > 1 kg and 23% gained > 1 kg. When adjusted for known prognostic covariates, baseline BMI (20–25 kg/m2) in those having palliative chemotherapy was independently associated with reduced survival compared to those with BMI indicating overweight (BMI 25–30 kg/m2) [HR: 1.80 (95% CI: 1.04–3.14), p = 0.037]. In those undergoing chemotherapy with palliative intent, a loss of > 6.4% subcutaneous fat (Q1 SAT) over 100 days was predictive of poor survival versus those with small losses, remaining stable or gaining SAT (Q2-4), independent of changes in muscle mass [HR: 2.22 (95% CI: 1.07–4.62), p = 0.033].Patients with CRC, particularly those treated with a palliative intent, experience significant losses in muscle and fat mass during chemotherapy. Loss of SAT mass during palliative chemotherapy is prognostic of poor survival, independent of changes in muscle mass. Baseline BMI in the overweight range confers a survival advantage. Nutritional strategies to prevent or attenuate weight loss during chemotherapy are advisable especially in the context of advanced CRC.

De novo epidermal growth factor receptor (EGFR) resistance mutations in tyrosine kinase inhibitor-naive patients are rare when assessed by standard genotyping methods. Patients with EGFR mutations were identified using PCR-based fragment length analysis, mass spectrometry-based genotyping (Sequenom), and Sanger sequencing. From 2008 to 2015, we observed de novo EGFR resistance mutations in 12.8 patients who received an EGFR TKI with an overall response rate of 25%, median PFS 24 months, and median OS 34 months. Five patients (63%) received erlotinib in the first-line setting with a 60% disease control rate (DCR) and a median duration of response of 6 months (range 4–45 months). Three (37%) received cytotoxic chemotherapy in the first-line setting with 67% DCR and a median duration of response of 11 months (range 10–12 months). In patients with de novo EGFR T790M mutations, 50% (2/4) had stable disease with one patient having an ongoing response to erlotinib of over 96 months. In patients with de novo EGFR S768I mutations who received erlotinib, 50% (2/4) have ongoing partial responses at 30 and 6 months. This is the largest Irish review of de novo synchronous EGFR mutations. The incidence of co-occurring EGFR mutations in our cohort of non-small cell lung carcinoma (NSCLCA) is 1% on routine assays. Erlotinib appears to have activity in this cohort in both in the first- and second-line setting. De novo S768I and T790M represent distinct clinical entities. For de novo T790M mutations cytotoxic chemotherapy may still be considered first line. For de novo S768I mutations, erlotinib appears to be a reasonable therapeutic option.

Background Malnutrition, weight loss, and muscle wasting are common in patients with foregut cancers (oesophagus, stomach, pancreas, liver, and bile ducts) and are associated with adverse clinical outcomes. However, little is known about the changes in body composition that occur in these patients during chemotherapy and its impacts clinical outcomes. Patients and methods A prospective study of adult foregut cancer patients undergoing chemotherapy between 2012 and 2016 was conducted. Computed tomography images were evaluated for cross-sectional skeletal muscle area (SMA) and adipose tissue area (ATA) at two time points [interval 118 days (IQR 92-58 days)]. Longitudinal changes in SMA and ATA were examined using paired t-tests. Sarcopenia and low muscle attenuation (MA) were defined using published cut-points. Cox proportional hazards models were used to estimate mortality hazard ratios for key predictors. Results A total of 225 foregut cancer patients were included (67% male, median age 66 years). At baseline, 40% were sarcopenic, 49% had low MA, and 62% had cancer cachexia. Longitudinal analysis (n = 163) revealed significant reductions in SMA [-6.1 cm2 (3.9%)/100 days, P 6.0%/100 days (highest fourth) independently predicted overall survival in patients receiving palliative chemotherapy [hazard ratio: 2.66, (95% CI: 1.42 to 4.97), P = 0.002]. Conclusions Patients with foregut cancers, particularly those treated with neoadjuvant chemotherapy, experience significant losses of muscle during chemotherapy. A high level of SMA loss is prognostic of reduced survival in patients treated with palliative chemotherapy. Multimodal interventions to stabilize or increase muscle mass and influence outcome warrant further investigation.

BACKGROUND Nutrition screening on admission to hospital is mandated in many countries, but to date, there is no consensus on which tool is optimal in the oncology setting. Wasting conditions such as cancer cachexia (CC) and sarcopenia are common in cancer patients and negatively impact on outcomes; however, they are often masked by excessive adiposity. This study aimed to inform the application of screening in cancer populations by investigating whether commonly used nutritional screening tools are adequately capturing nutritionally vulnerable patients, including those with abnormal body composition phenotypes (CC, sarcopenia, and myosteatosis). METHODS A prospective study of ambulatory oncology outpatients presenting for chemotherapy was performed. A detailed survey incorporating clinical, nutritional, biochemical, and quality of life data was administered. Participants were screened for malnutrition using the Malnutrition Universal Screening Tool (MUST), Malnutrition Screening Tool (MST), and the Nutritional Risk Index (NRI). Computed tomography (CT) assessment of body composition was performed to diagnose CC, sarcopenia, and myosteatosis according to consensus criteria. RESULTS A total of 725 patients (60% male, median age 64 years) with solid tumours participated (45% metastatic disease). The majority were overweight/obese (57%). However, 67% were losing weight, and CT analysis revealed CC in 42%, sarcopenia in 41%, and myosteatosis in 46%. Among patients with CT-identified CC, the MUST, MST, and NRI tools categorized 27%, 35%, and 7% of them as 'low nutritional risk', respectively. The percentage of patients with CT-identified sarcopenia and myosteatosis that were categorised as 'low nutritional risk' by MUST, MST and NRI were 55%, 61%, and 14% and 52%, 50%, and 11%, respectively. Among these tools, the NRI was most sensitive, with scores

Leydig cell tumour (LCT) of the testis is a rare histological subtype of stromal tumours, accounting for 1 to 3% of testicular neoplasms. The natural history of LCT is poorly understood. The aim of this study was to assess the incidence and natural history of Leydig cell tumours (LCT) of the testes. A search of the National Cancer Registry of Ireland database was performed regarding Leydig cell testicular tumours. Recurrence free survival (RFS) and disease-specific survival (DSS) were analysed. Between 1994 and 2013, 2755 new cases of testicular cancer were diagnosed in Ireland. Of these, 22 (0.79%) were Leydig cell tumours. Nineteen were invasive (stage T1) and three were in situ (stage Tis). One patient developed a local recurrence following an organ preserving procedure and underwent a completion orchidectomy 107 days after initial diagnosis. No further treatment was required. There have been no disease-specific deaths. The 1-, 3- and 5-year overall survival (OS) rates were 95.5, 88.2 and 73.3%, respectively. The 5-year disease-specific survival (DSS) was 100% and the 5-year recurrence free survival (RFS) was 93.3%. From the National Cancer Registry, LCT has been shown to be a rare subtype of testicular tumour. Due to the relatively favourable natural history, it may be possible to tailor less aggressive surveillance regimens in these patients.

AimsThe assessment of B-raf proto-oncogene, serine/threonine kinase (BRAF) gene status is now standard practice in patients diagnosed with metastatic melanoma with its presence predicting a clinical response to treatment with BRAF inhibitors. The gold standard in determining BRAF status is currently by DNA-based methods. More recently, a BRAF V600E antibody has been developed. We aim to investigate whether immunohistochemical detection of BRAF mutation is a suitable alternative to molecular testing by polymerase chain reaction (PCR).MethodsWe assessed the incidence of BRAF mutation in our cohort of 132 patients, as determined by PCR, as well as examining clinical and histopathological features. We investigated the sensitivity and specificity of the anti-BRAF V600E VE1 clone antibody in detecting the presence of the BRAF V600E mutation in 122 cases deemed suitable for testing.ResultsThe incidence of BRAF mutation in our cohort was 28.8% (38/132). Patients with the BRAF mutation were found to be significantly younger at age of diagnosis. BRAF-mutated melanomas tended to be thinner and more mitotically active. The antibody showed a sensitivity of 86.1% with a specificity of 96.9%. The positive predictive value was 96.9%; the negative predictive value was 94.4%. The concordance rate between PCR and immunohistochemical BRAF status was 95.1% (116/122).ConclusionsThe rate of BRAF mutation in our cohort (28.8%) was lower than international published rates of 40%–60%. This may reflect ethnic or geographic differences within population cohorts. The high concordance rate of PCR and immunohistochemical methods in determining BRAF status suggests that immunohistochemistry is potentially a viable, cost-effective alternative to PCR testing and suitable as a screening test for the BRAF mutation.

Sunitinib is a standard first-line option for metastatic renal cell carcinoma (mRCC). Body composition is a prognostic factor in cancer patients and patients with loss of skeletal muscle mass and fat-free mass (FFM) are prone to dose-limiting toxicity (DLT) during targeted drug therapy. We investigated whether body composition by computed tomography predicted DLT from sunitinib in mRCC.Patients with clear cell mRCC receiving sunitinib (50 mg) were included. Skeletal muscle cross-sectional area at L3 was measured by computed tomography. Sarcopenia was defined using published cutoffs. Toxicity was assessed after 4 cycles of the drug.Fifty-five patients (43 male), mean age 64 years were included. Overall, 33% (N=18) of all patients were sarcopenic and of these 12.7% (N=7) were sarcopenic and overweight or obese. DLT occurred in6 months in 53% of patients (44% male vs. 83% female) and those who experienced DLT were older (68 vs. 60 y), had a lower skeletal muscle index (51.7 vs. 59.4 cm/m), a lower FFM (51.4 vs. 57.7 kg), and received a higher drug dose in mg/kg FFM (0.9 vs. 0.8). Patients with the lowest compared with the highest measurements of skeletal muscle mass experienced more DLT, respectively, 92% versus 57% and experienced on average 5 toxicities versus 2.Sarcopenia is prevalent in patients with mRCC, is an occult condition in patients with normal/high body mass index, and is a significant predictor of DLT in patients receiving sunitinib. Our results highlight the potential use of baseline body composition to predict toxicity.

There is no standard of care in the UK or Ireland for second-line chemotherapy for patients with advanced transitional cell carcinoma (TCCU). Vinflunine is approved for TCCU patients who have failed a platinum-based regimen, and is standard of care in Europe but is not routinely available in the UK. Data were collected retrospectively on patients who received vinfluine as a second-line treatment. The aims were to document the toxicity and efficacy in a real life setting. Data were collected on 49 patients from 9 sites across the UK and Ireland [median age, 64 (IQR, 57-70) years, 33 males]. All patients had advanced metastatic TCCU. Thirteen patients had bone or liver metastases, 4 patients had PS 2 and 11 patients had HB < 10. Median vinflunine administration was 3.5 cycles (range 1-18). Most common grade 3-4 toxicities were constipation (4 patients) and fatigue (3 patients). Partial response rate was 29% (14 PR, 11 SD, 19 PD, 4 NE, 1 not available). Median OS was 9.1 (6.0, 12.7) months. Results are consistent with real life data from Europe. Toxicity is further reduced with prophylactic laxative and oral antibiotics. Vinflunine is an efficient and tolerable second line treatment in advanced TCCU.

Background: Body composition is an important predictor of drug toxicity and outcome. Ipilimumab (Ipi), a monoclonal antibody used to treat metastatic melanoma, has specific toxicities. No validated biomarkers that predict Ipi toxicity and efficacy exist. Also, the impact of Ipi on body composition has not been established. Methods: Patients with metastatic melanoma treated with Ipi between 2009 and 2015 were included. Body composition was assessed by computed tomography at baseline and after four cycles of Ipi. Sarcopenia and low muscle attenuation (MA) were defined using published cut-points. All adverse events (AEs) and immune-related AEs (irAEs) were recorded (Common Terminology Criteria For Adverse Event V.4.0). Results: Eighty-four patients were included in this study (62% male, median age 54 years). At baseline, 24% were sarcopenic and 33% had low MA. On multivariate analysis, sarcopenia and low MA were significantly associated with high-grade AEs (OR = 5.34, 95% CI: 1.15- 24.88, P = 0.033; OR = 5.23, 95% CI: 1.41-19.30, P = 0.013, respectively), and low MA was associated with high-grade irAEs (OR = 3.57, 95% CI: 1.09-11.77, P = 0.036). Longitudinal analysis (n = 59) revealed significant reductions in skeletal muscle area (SMA), total body fat-free mass, fat mass (all P= 7.5%/ 100 days (highest quartile) was a significant predictor of overall survival in multivariable Cox regression analysis (HR: 2.1, 95% CI: 1.02-4.56, P = 0.046). Conclusions: Patients with sarcopenia and low MA are more likely to experience severe treatment-related toxicity to Ipi. Loss of muscle during treatment was predictive of worse survival. Treatments to increase muscle mass and influence outcome warrant further investigation.

Background Weight loss (WL) has long been recognized as an important factor associated with reduced quality of life (QoL) and reduced survival in patients with cancer. The body mass index (BMI)‐adjusted weight loss grading system (WLGS) has been shown to be associated with reduced survival. However, its impact on QoL has not been established. The aim of this study was to assess the relationship between this WLGS and QoL in patients with advanced cancer. Methods A biobank analysis was undertaken of adult patients with advanced cancer. Data collected included patient demographics, Eastern Cooperative Oncology Group performance status, and anthropometric parameters (BMI and %WL). Patients were categorized according to the BMI‐adjusted WLGS into one of five distinct WL grades (grades 0–4). QoL was collected using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire‐C30. The Kruskal–Wallis test and multivariate logistic regression analyses were used to assess the relationship between the WLGS and QoL scores. Overall survival was assessed using Kaplan–Meier curve and Cox proportional hazard models. Results A total of 1027 patients were assessed (51% male, median age: 66 years). Gastrointestinal cancer was most prevalent (40%), and 87% of patients had metastatic disease. Half (58%) of patients had a WL grade of 0–1, while 12%, 20%, and 10% had WL grades of 2, 3, and 4, respectively. Increasing WL grades were significantly associated with poorer QoL functioning and symptoms scales (all P < 0.05). Physical, role, and emotional functioning decreased by a median of >20 points between WL grade 0 and WL grade 4, while appetite loss, pain, dyspnoea, and fatigue increased by a median score >20 points, indicative of a large clinical significant difference. Increasing WL grades were associated with deteriorating QoL summary score. WL grades 2, 3, and 4 were independently associated with a QoL summary score below the median (

Aims and objectives: To measure cancer-related fatigue (CRF), self-care agency (SCA) and fatigue self-care strategies, and to explore the relationship between CRF and SCA. Background: Cancer-related fatigue has been consistently rated as the most elusive, common and severe of symptoms that patients with cancer undergoing chemotherapy experience. Despite its frequency and severity, CRF is poorly managed. A renewed focus on supporting self-care among patients with cancer has been found to reduce symptom burden, empower patients and improve patient satisfaction. Understanding the link between self-care agency (i.e. capability and willingness to self-care) and CRF levels will help practitioners to better support individuals on the cancer journey. Design: A descriptive, correlational survey design was employed. Methods: Patients (n = 362) undergoing chemotherapy with a primary diagnosis of breast, colorectal, Hodgkin's and non-Hodgkin's lymphoma cancers were recruited from four oncology centres in one city in the South of Ireland. Participants completed the Piper Fatigue Scale-Revised, Appraisal of Self-care Agency Scale and a researcher-developed Fatigue Self-Care Survey. Multivariate logistic regression was used to examine the relationship between CRF and self-care agency using a dichotomous dependent variable score of four as the cut-off between those deemed to be fatigued (≥4) and those not fatigued (

1 Background: Innovation in the treatment of genitourinary (GU) malignancies is accelerating, however, many of these new treatments are often not available for patients. We sought to investigate patient access, cost and value of new systemic anti-cancer compounds (SACTs) in GU oncology. We compared the US and Europe with a focus on the United Kingdom (UK) and the Republic of Ireland (IRL). Methods: Data on licensing and reimbursement decisions was collected on SACTs approved for GU oncology between 01/01/2010 to 09/01/2020. Overall survival (OS) benefit, progression free survival (PFS) benefit and cost of therapy were included in our analysis. Results: There were 29 regimens/indications approved by the Federal Drug Agency (FDA) for GU malignancies between 2010 and 2020. The majority of these (21/29, 72%) were also approved by the European Medicines Agency (EMA). Nearly all regimens/indications were approved by the FDA prior to the EMA (27/29, 93%), with a median time to EMA approval of 4 months (SD = 6, range -6 to 17). Only a minority of these regimens/indications are reimbursed by the public health systems in the UK (12/29, 41%) and IRL (6/29, 21%). Following EMA approval, public reimbursement of these regimens in the UK and IRL is often delayed with a median time of 8 months (+/- 6.3, range 4 - 21) and 11.5 months (+/- 12.5, range 0 - 33) respectively. Approximately half (15/29, 52%) of all reimbursed regimens/indications have demonstrated an overall survival benefit for patients. Androgen signalling inhibitors (ASIs) are more likely to have a proven OS benefit and had a lower mean cost than non-ASI regimens (See Table). A significant minority of regimens/indications (6/29, 21%) have demonstrated neither an OS or PFS benefit. The median price per month (USA list price) was $15,086 +/- $7,019. Regimens with a proven OS benefit were not more expensive than those without ($14,229 +/- $6,466 versus $16,004 +/- $7,704). There was no significant correlation between the length of OS benefit and the cost of regimens (Pearson’s Correlation Coefficient = -2.72, p = 0.445). Conclusions: Patients in the UK and IRL experience clinically significant delays in accessing FDA approved regimens in GU oncology. Only 52% of these regimens have a proven OS benefit. In our study, ASI regimens are cheaper and more effective than non-ASI regimens. There is no association between overall survival benefit and list prices in the USA. We need to radically overhaul licensing and funding of SACTs in GU oncology to ensure continued access for patients to effective medicines. [Table: see text]

469 Background: There are significant disparities in patient access to innovative cancer medicines internationally. We sought to describe global drug licensing developments in gastrointestinal (GI) oncology from 2010 – 2020. We compared US, European, UK and Irish patient access to these drugs, their cost and associated efficacy. Methods: Data was collected from public sources online including the FDA, European Medicines Agency (EMA), the UK National Institute of Clinical Excellence (NICE) and the Irish National Cancer Control Programme (NCCP). Anti-cancer compounds approved for GI malignancies between January 1, 2010 and September 1, 2020 were recorded. Approval publications and updated survival analysis outcomes were included to assess for demonstrable overall survival (OS) and/or progression free survival (PFS) benefit. Results: There were 26 regimens approved by the FDA for GI malignancies between 2010 and 2020. Slightly over half (n=15, 57.7%) of these regimens were approved by the EMA. The median time from FDA to EMA approval was 3 months (mo) +/- 5 mo. Only a small minority of these regimens were funded for patients in the UK (including the Cancer Drugs Fund, 9 regimens, 31%) or Ireland (IRL) (7 regimens, 27%). The median time from EMA approval to patient access was short in both of these countries (3.5 mo (UK) and 0.5 m (IRL)). However, the range in these countries was large (2 - 73 mo (UK) & 0-24 mo (IRL)). More than half of regimens (15, 57.7%) demonstrated an OS benefit. Of the remaining 11 regimens, a further 6 drugs (23%) demonstrated a PFS benefit. The median OS benefit (if present) was 2.3 mo +/- 3 mo. The median price of these regimens in the USA (list price) was $13,758 per month +/- $5,152. Regimens which demonstrated an OS benefit were not more expensive than those that did not (median $13,065 versus $13,758 respectively, p < 0.05). For regimens with an OS benefit, there was no statistically significant correlation between the length of OS benefit and drug cost (Pearson’s correlation = 0.32, p = 0.07). Conclusions: Less than one third of patients in the UK and Ireland have access to medicines approved by the FDA for GI malignancies between 2010 – 2020. Overall survival benefits are often modest, or absent. The cost of regimens in the USA commonly exceeds $100,000/year irrespective of OS benefit. Our work highlights the necessity to develop a value based-pricing system in GI oncology.

236 Background: Gastric adenocarcinoma is the fourth most frequent cancer worldwide and the second leading cause of cancer deaths. According to The Cancer Genome Atlas (TCGA) 9% of gastric carcinomas are associated with Epstein-Barr Virus (EBV). EBV- associated gastric carcinoma (EBV-GC) has distinct clinicopathological features, with a marked lymphocytic infiltrate, a generally diffuse histological type and a better prognosis. The immune cell infiltration in EBV-GC suggests a role for immune checkpoint inhibition, which currently has modest activity in unselected gastric cancer. Methods: All cases of gastric or junctional adenocarcinoma diagnosed between Jan 2019 and March 2020 in Mater Misericordiae University Hospital (MMUH) and Jan 2017 and Jan 2019 in Cork University Hospital (CUH) were identified. Electronic medical records were retrospectively reviewed to collect demographic and clinicopathological data such as AJCC TNM stage, tumour subtype and grade, HER-2 status, MMR proficiency and EBV status as determined by EBV-encoded RNA in situ hybridization. Results: N = 103 cases of gastric or junctional adenocarcinoma were identified. 67 male, 36 female, median age 64.5 (range 34 – 95). 40/103 had undergone surgical resection. EBER-ISH was assessed in all patients. 8 of 103 (7.8%) patients showed EBV positivity. These cases were all male patients, median age 62 (range 51-73). The tumours were located as follows; 2 in the cardia, 5 in the body and 1 not documented. The specimens were graded as; 87.5% (7/8) tumours being poorly differentiated and 1/8 moderate to poorly differentiated. The tumour subtypes were specified as; 62.5% (5/8) diffuse, 12.5% (1/8) intestinal and 25% (2/8) mixed intestinal and diffuse. 5/8 patients were locally confined and underwent resection for N0 disease. 3/8 (37.5%) patients had metastatic disease. None of the 8 EBV-GC cases were identified as being HER-2 positive or MMR-deficient. Conclusions: EBV-GC accounted for 7.8% of all gastric cancers in two large tertiary referral centres in Ireland. 37.5% of these patients had metastatic disease. Given this frequency and a possible predictive role in selecting for immunotherapy we conclude that routine assessment of EBV status is feasible in advanced gastric cancer.

Urachal carcinoma is an uncommon cancer whose rarity has precluded its study and evidence-based management strategies are lacking. This study assessed all urachal carcinomas in Ireland and clinical parameters in order to improve understanding. Urachal carcinomas diagnosed from 1994 to 2011 were identified from the National Cancer Registry in Ireland. Data obtained included patient age, gender, diagnostic year, pathology, tumor stage, patient treatment strategies and survival. Twenty-six urachal carcinomas were identified, the majority being adenocarcinoma. This comprised 0.3% of all invasive bladder tumors. Patients were predominantly male (62%) and over 50 years of age (58%). Twenty-two patients (85%) underwent surgery, with only six (23%) undergoing chemotherapy. On average, median overall survival was 2.6 years (range 0-15.2 yrs). Survival was longer in women (5 vs. 1.9 yrs), patients under 50 years of age (3.6 vs. 1.9 yrs), those without confirmed metastasis (4.1 vs. 0.7 yrs) and those who received chemotherapy (3.6 vs. 2.6 yrs). The overall survival of urachal carcinoma in Ireland is less than expected from published literature. This study highlights the need for centralization of rare tumors with international collaboration to identify the optimal treatment strategy and improve outcome.

Increased glycolysis is the main source of energy supply in cancer cells that use this metabolic pathway for ATP generation. Altered energy metabolism is a biochemical fingerprint of cancer cells that represents one of the "hallmarks of cancer". The immune system can prevent tumour growth by eliminating cancer cells but this editing process ultimately results in poorly immunogenic cells remaining allowing for unchallenged tumour growth. In this review we look at the glycolysis pathway as a target for cancer treatments. We also examine the interplay between the glycolysis modulation and the immune response as an anti-cancer therapy.

Summary Background Body composition may influence clinical outcomes of certain chemotherapeutic agents. We examined the prognostic significance of skeletal muscle mass and adipose tissue on docetaxel toxicity and overall survival in patients with metastatic castrate resistant prostate cancer (mCRPC). Methods A retrospective review of patients medical records with mCRPC, treated with docetaxel was conducted. Body composition parameters (skeletal muscle mass, muscle attenuation [MA], visceral and subcutaneous adipose tissue) were measured at L3 by computed tomography (CT) and defined using previously established cut points. Toxicity profile was assessed after 3 cycles of the drug and graded according to the National Cancer Institute Common Toxicity Criteria (version 4). Overall survival was analysed. Results Overall 63 patients, mean age 69 years (SD 8.3), were included. Sarcopenia was present in 47% (n = 30) and of these 26.7% (8/30) were sarcopenic obese. Common toxicities (all grades) observed included fatigue (80.9%), pain (46%), and constipation (34.9%). DLT occurred in 22 (34.9%) patients; of these 10 patients (15.8%) experienced dose reductions and 12 patients (19%) experienced dose terminations. Measurements of adiposity were not predictive of DLT, however 59.1% patients who had a combination of both sarcopenia and low MA experienced DLT compared to 29.3% of patients without sarcopenia and low MA (p = 0.021). Skeletal muscle index and MA were significantly lower in patients who experienced neutropenia (grade I–II) (46.5 cm 2 /m 2 vs. 51.2 cm 2 /m 2 , p = 0.005) compared to their counterparts (24.6 HU vs. 32.2 HU, p = 0.044). Neither sarcopenia nor sarcopenic obesity was associated with overall survival. In multivariate analysis, BMI ≥25 kg/m 2 (HR: 0.349, CI: 0.156–0.782, p = 0.010) was a significant predictor of longer overall survival and both visceral fat index ≥ median 58.7 cm 2 /m 2 (HR: 2.266 CI: 1.066–4.814, p = 0.033) and anaemia (HR: 2.81, CI: 1.297–6.091, p = 0.009) were significant predictors of shorter overall survival. Conclusions Sarcopenia and low MA are associated with neutropenia (grade I–II). Furthermore, presence of anaemia, high volume of visceral fat and BMI 2 are associated with reduced survival in patients with castrate resistant prostate cancer being treated with docetaxel chemotherapy.

Highlights • Radiologists should endeavour to minimise radiation exposure to patients with testicular cancer. • Iterative reconstruction algorithms permit CT imaging at lower radiation doses. • Image quality for reduced-dose CT–MBIR is at least comparable to conventional dose. • No loss of diagnostic accuracy apparent with reduced-dose CT–MBIR., Purpose We examine the performance of pure model-based iterative reconstruction with reduced-dose CT in follow-up of patients with early-stage testicular cancer. Methods Sixteen patients (mean age 35.6 ± 7.4 years) with stage I or II testicular cancer underwent conventional dose (CD) and low-dose (LD) CT acquisition during CT surveillance. LD data was reconstructed with model-based iterative reconstruction (LD–MBIR). Datasets were objectively and subjectively analysed at 8 anatomical levels. Two blinded clinical reads were compared to gold-standard assessment for diagnostic accuracy. Results Mean radiation dose reduction of 67.1% was recorded. Mean dose measurements for LD–MBIR were: thorax – 66 ± 11 mGy cm (DLP), 1.0 ± 0.2 mSv (ED), 2.0 ± 0.4 mGy (SSDE); abdominopelvic – 128 ± 38 mGy cm (DLP), 1.9 ± 0.6 mSv (ED), 3.0 ± 0.6 mGy (SSDE). Objective noise and signal-to-noise ratio values were comparable between the CD and LD–MBIR images. LD–MBIR images were superior (p

EGFR mutated lung cancer represents a subgroup with distinct clinical presentations, prognosis, and management requirements. We investigated the survival, prognostic factors, and real-world treatment of NSCLC patients with EGFR mutation in clinical practice. A retrospective review of all specimens sent for EGFR analysis from December 2009 to September 2015 was performed. Patient demographics, specimen type, EGFR mutation status/type, stage at diagnosis, treatment, response rate, and survival data were recorded. 27/334 (8%) patient specimens sent for EGFR testing tested positive for a sensitising EGFR mutation. The median age was 65 years (40–85 years). Exon 19 deletion represented the most commonly detected alteration, accounting for 39% (n = 11). First-line treatment for those with Exon 18, 19, or 21 alterations (n = 24) was with an EGFR tyrosine kinase inhibitor (TKI) in 79% (n = 19). Objective response rate among these patients was 74% and median duration of response was 13 months (range 7–35 months). The incidence of EGFR mutation in our cohort of NSCLC is 9% which is consistent with mutation incidence reported in other countries. The rate of EGFR mutation in our population is slightly below that reported internationally, but treatment outcomes are consistent with published data. Real-world patient data have important contributions to make with regard to quality measurement, incorporating patient experience into guidelines and identifying safety signals.
