Purpose: Using population-based data for women diagnosed with stage I-III breast cancer, our aim was to examine the impact of time to treatment completion on survival and to identify factors associated with treatment delay., Methods: This retrospective study used clinical and treatment data from the Queensland Oncology Repository. Time from diagnosis to completing surgery, chemotherapy and radiation therapy identified a cut-off of 37 weeks as the optimal threshold for completing treatment. Logistic regression was used to identify factors associated with the likelihood of completing treatment > 37 weeks. Overall (OS) and breast cancer-specific survival (BCSS) were examined using Cox proportional hazards models., Results: Of 8279 women with stage I-III breast cancer, 31.9% completed treatment > 37 weeks. Apart from several clinical factors, being Indigenous (p = 0.002), living in a disadvantaged area (p = 0.003) and receiving ≥ two treatment modalities within the public sector (p < 0.001) were associated with an increased likelihood of completing treatment > 37 weeks. The risk of death from any cause was about 40% higher for women whose treatment went beyond 37 weeks (HR 1.37, 95%CI 1.16-1.61), a similar result was observed for BCSS. Using the surgery + chemotherapy + radiation pathway, a delay of > 6.9 weeks from surgery to starting chemotherapy was significantly associated with poorer survival (p = 0.001)., Conclusions: Several sociodemographic and system-related factors were associated with a greater likelihood of treatment completion > 37 weeks. We are proposing a key performance indicator for the management of early breast cancer where a facility should have > 90% of patients with a time from surgery to adjuvant chemotherapy < 6.9 weeks., (© 2022.

Background: Disparity in outcomes between Indigenous and non-Indigenous people after cancer diagnosis is multifactorial, including lower cancer screening participation, later diagnosis, reduced access and uptake of cancer treatment, higher rate of comorbidities, and barriers accessing the health system. Little is known about cancer survivorship experiences., Objective: The aim of this study was to explore Indigenous Australian cancer survivor's perspectives of cancer survivorship., Methods: Indigenous people who completed cancer treatment 6 months to 5 years before fieldwork were recruited from a tertiary hospital and remote primary health service for this qualitative study. Data collection was guided by yarning methods, a culturally appropriate method emphasizing storytelling. Data were interpreted using a social constructionist framework., Results: Thirteen women and 6 men were interviewed. Participants' past experiences contributed to their specific identity as survivors. Participants described factors affecting a positive transition from cancer patient to cancer survivor and the importance of ongoing family support in helping to manage survivorship. Finally, participants described a range of community support they received and provided to others and how this improved their cancer survivorship., Conclusion: Although a range of experiences are presented, this study provides evidence that the survivorship perspectives of Indigenous cancer survivors may be, in part, shared by non-Indigenous cancer survivors., Implications for Practice: Acknowledging Indigenous cancer survivors' past experiences and how these influence their overall well-being is important for providing patient-centered and culturally appropriate care. Nurses and other healthcare professionals may use this knowledge to foster a range of coping strategies to assist Indigenous cancer survivors to live well.

Background: Patients with oesophageal/gastro-oesophageal junction adenocarcinoma (EAC) not showing early metabolic response (EMR) to chemotherapy have poorer survival and histological response rates <5%. We investigated whether tailoring neoadjuvant therapy can improve outcomes in these patients., Patients and Methods: Patients with resectable EAC were enrolled and randomised into two single-arm, multicentre phase II trials. After induction cisplatin and 5-fluorouracil (CF), all were assessed by day 15 positron emission tomography (PET). Patients with an EMR [maximum standardised uptake values (SUVmax) ≥35% reduction from baseline to day 15 PET] received a second CF cycle then oesophagectomy. Non-responders were randomised 1 : 1 to two cycles of CF and docetaxel (DCF, n = 31) or DCF + 45 Gy radiotherapy (DCFRT, n = 35) then oesophagectomy. The primary end point was major histological response (<10% residual tumour) in the oesophagectomy specimen; secondary end points were overall survival (OS), progression-free survival (PFS), and locoregional recurrence (LR)., Results: Of 124 patients recruited, major histological response was achieved in 3/45 (7%) with EMR, 6/30 (20%) DCF, and 22/35 (63%) DCFRT patients. Grade 3/4 toxicities occurred in 12/45 (27%) EMR (CF), 13/31 (42%) DCF, and 25/35 (71%) DCFRT patients. No treatment-related deaths occurred. LR by 3 years was seen in 5/45 (11%) EMR, 10/31 (32%) DCF, and 4/35 (11%) DCFRT patients. PFS [95% confidence interval (CI)] at 36 months was 47% (31% to 61%) for EMR, 29% (15% to 45%) for DCF, and 46% (29% to 61%) for DCFRT patients. OS (95% CI) at 60 months was 53% (37% to 67%) for EMR, 31% (16% to 48%) for DCF, and 46% (29% to 61%) for DCFRT patients., Conclusions: EMR is associated with favourable OS, PFS, and low LR. For non-responders, the addition of docetaxel augmented histological response rates, but OS, PFS, and LR remained inferior compared with responders. DCFRT improved histological response and PFS/LR outcomes, matching the EMR group. Early PET/CT has the potential to tailor therapy for patients not showing an early response to chemotherapy., Trial Registration: ACTRN12609000665235., (Crown Copyright © 2019.

Purpose: Many cancer-specific assessment tools to measure health care performance have been developed. However, reporting on quality indicators at a population level is uncommon. We describe the development and implementation of a Cancer Quality Index (CQI) and examine the sensitivity of the index to detect change over time., Methods: In developing the CQI, we reviewed existing indices, guidelines, and cancer care pathways. Our choice of indicators was additionally guided by the availability of population-wide data. A series of pilot indicators underwent trial use and were evaluated, and outcomes were discussed before a final set of indicators was established. The process was overseen by a clinician-led quality assurance committee that included hospital administrators and data custodians., Results: The CQI includes five quality dimensions and 16 indicators for public and private cancer services using population-wide information. The following are the five indicators: Effective, Efficient, Safe, Accessible, and Equitable. We demonstrated the sensitivity of the CQI to measure change over time by examining outcomes such as time to first treatment and 30-day surgical mortality, using linked cancer registry and health administrative data for 99,728 patients with cancer diagnosed between 2005 and 2009 and 2010 and 2014., Conclusion: The CQI is a valuable tool to track progress in delivering safe, quality cancer care within health care services. Critical to its development and implementation has been the involvement of clinicians from several disciplines and the availability of population-based data. We found the CQI to be a sensitive tool able to detect changes over time.

Although T-cell checkpoint blockade has revolutionized melanoma therapy, metastatic melanoma in pregnancy remains a challenging area of unmet need. Treatment with anti-PD1 therapy decreases foetal-maternal tolerance and increases the risk of pregnancy loss in animal studies and is considered category D by the Food and Drug Administration. We describe a unique case of conception and pregnancy, with successful maternal and foetal outcomes, in a patient with metastatic melanoma who had received combination anti-CTLA-4 and anti-PD1 therapy. A 32-year-old G0P0 lady, with a 10-year history of infertility of unclear cause, was found to be 7 weeks pregnant after 14 months of nivolumab maintenance therapy, having previously received combination ipilimumab and nivolumab. Nivolumab was ceased upon discovery of pregnancy in the first trimester. The patient had an uneventful pregnancy, followed by spontaneously premature labour, and delivered by caesarean section at 33 weeks' gestation. The foetus had moderate intrauterine growth restriction, as well as congenital hypothyroidism, which possibly constitutes the first documented case of foetal immune-related adverse event from maternal anti-PD1 exposure. No adverse events were noted in the mother. At 6 months of follow-up postpartum, the mother had a sustained complete response to treatment, and the baby had appropriate weight gain with normal developmental milestones. We summarize and discuss the available literature of immune checkpoint inhibitor exposure in pregnancy, which consists of a total of three case reports.

Indigenous Australians diagnosed with cancer experience higher mortality and lower survival rates compared to non-Indigenous Australians. Reasons are multifaceted and complex. Knowledge about Indigenous cancer survivors' perspectives of positive cancer survivorship is a gap in research evidence. The study explored cancer survivorship perspectives of Indigenous cancer survivors, their support people and healthcare workers with a view to developing recommendations for cancer survivorship. Indigenous Australians who completed cancer treatment in the previous 6 months to 5 years, their support people and primary healthcare workers were recruited from primary healthcare centres and a large tertiary Queensland hospital. Semi-structured interviews and focus groups were conducted with written and informed consent obtained prior. Participants emphasised key action areas and recommendations to enhance cancer survivorship, namely: establishing a community cancer advocate and peer support program, availability and use of a cancer-specific Indigenous primary healthcare worker and hospital-based Indigenous patient navigator, as well as adoption of question prompt lists and cancer survivorship care plans. Existing research suggests significant benefits from implementing the key recommendations identified in this study. Greater support and commitment across health sectors and funding bodies is needed to promote institutional change and health system development.

Background: The optimal treatment strategy for patients with esophageal adenocarcinoma (EAC) remains undetermined. This study compared outcomes in patients undergoing neoadjuvant chemotherapy (nCT) and neoadjuvant chemoradiotherapy (nCRT) for EAC., Methods: Patients who underwent nCT or nCRT followed by surgery for EAC were identified from a prospective database (2000-2017) and included. After propensity score matching, the impact of the treatments on postoperative complications, in-hospital mortality, pathological outcomes, and survival rates were compared., Results: Of the 396 eligible patients, 262 patients were analysed following matching with 131 patients in both groups. There were no significant differences between the nCT and nCRT groups for overall complications (59% vs 57%, P = 0.802) or in-hospital mortality (2% vs 0%, P = 0.156). Patients who had nCRT had more R0 resections (93% vs 83%, P = 0.013), and higher pathological complete response rates (15% vs 5%, P < 0.001). No differences in 5-year overall survival rates (nCT vs nCRT; 44% vs 33%, P = 0.645) were found., Conclusion: In this study no differences between nCT and nCRT were seen in postoperative complications and in-hospital mortality in patients treated for EAC. Inspite of improved complete resection and pathological response there was no difference in the overall survival between the treatment modalities., (© 2018 Wiley Periodicals, Inc.)

Background: Aboriginal and Torres Strait Islander Australians have poorer cancer outcomes and experience 30% higher mortality rates compared to non-Indigenous Australians. Primary health care (PHC) services are increasingly being recognized as pivotal in improving Indigenous cancer patient outcomes. It is currently unknown whether patient information systems and practices in PHC settings accurately record Indigenous and cancer status. Being able to identify Indigenous cancer patients accessing services in PHC settings is the first step in improving outcomes., Methods: Aboriginal Medical Centres, mainstream (non-Indigenous specific), and government-operated centers in Queensland were contacted and data were collected by telephone during the period from 2014 to 2016. Participants were asked to (i) identify the number of patients diagnosed with cancer attending the service in the previous year; (ii) identify the Indigenous status of these patients and if this information was available; and (iii) advise how this information was obtained., Results: Ten primary health care centers (PHCCs) across Queensland participated in this study. Four centers were located in regional areas, three in remote areas and three in major cities. All participating centers reported ability to identify Indigenous cancer patients attending their service and utilizing electronic Patient Care Information Systems (PCIS) to manage their records; however, not all centers were able to identify Indigenous cancer patients in this way. Indigenous cancer patients were identified by PHCCs using PCIS ( n  = 8), searching paper records ( n  = 1), and combination of PCIS and staff recall ( n  = 1). Six different types of PCIS were being utilized by participating centers. There was no standardized way to identify Indigenous cancer patients across centers. Health service information systems, search functions and capacities of systems, and staff skill in extracting data using PCIS varied between centers., Conclusion: It is crucial to be able to easily identify Indigenous cancer patients accessing health services in the PHC setting to monitor progress, improve and evaluate care, and ultimately improve Indigenous cancer outcomes. It is also important for PHC staff to receive adequate training and support to utilize PCISs efficiently and effectively.

Purpose: The purpose of the present study is to explore the role of the general practitioners, family physicians and primary care physicians (GP) in the provision of follow-up cancer care., Methods: PubMed, MEDLINE and CINAHL were systematically searched for primary research focussing on the role of the GP from the perspective of GPs and patients. Data were extracted using a standardised form and synthesised using a qualitative descriptive approach., Results: The initial search generated 6487 articles: 25 quantitative and 33 qualitative articles were included. Articles focused on patients' and GPs' perspectives of the GP role in follow-up cancer care. Some studies reported on the current role of the GP, barriers and enablers to GP involvement from the perspective of the GP and suggestions for future GP roles. Variations in guidelines and practice of follow-up cancer care in the primary health care sector exist. However, GPs and patients across the included studies supported a greater GP role in follow-up cancer care. This included greater support for care coordination, screening, diagnosis and management of physical and psychological effects of cancer and its treatment, symptom and pain relief, health promotion, palliative care and continuing normal general health care provision., Conclusion: While there are variations in guidelines and practice of follow-up cancer care in the primary health care sector, GPs and patients across the reviewed studies supported a greater role by the GP., Implications for Cancer Survivors: Greater GP role in cancer care could improve the quality of patient care for cancer survivors. Better communication between the tertiary sector and GP across the cancer phases would enable clear delineation of roles.

Purpose: To evaluate changes in cancer mortality burden over time by assessing temporal trends in life expectation for Australian residents diagnosed with cancer., Methods: The study cohort consisted of all people diagnosed with cancer in the period 1990-2000 and aged 15-89 years (n = 1,275,978), with mortality follow-up to 31 December 2010. Flexible parametric survival models incorporating background age-sex-year-specific population mortality rates were applied to generate the observed survival curves for all cancers combined and selected major cancer types. Predicted values of loss of life expectancy (LOLE) in years were generated and then averaged across calendar year and age group (15-49, 50-69 and 70-89 years) or spread of disease (localized, regional, distant, unknown)., Results: The greatest LOLE burden was for lung cancer (14.3 years per diagnosis) and lowest for melanoma (2.5 years). There was a significant decrease in LOLE over time (-0.13 LOLE per year) for all cancers combined. Decreases were also observed for female breast cancer (-0.21), prostate cancer (-0.17), colorectal cancer (-0.08), melanoma (-0.07) and stomach cancer (-0.02), with slight increases for lung cancer (+0.04). When restricted to the sub-cohort from New South Wales with spread of disease information, these decreases in LOLE were primarily among cancers categorized as localized or regional spread at diagnosis., Conclusions: In Australia, persons diagnosed with cancer have a steadily improving outlook that exceeds that expected by general improvement in population life expectancy. The overall improvement is observed in persons with localized or regional cancers but not in those with advanced cancers, findings which encourage earlier diagnosis.

Aims: Perioperative chemotherapy has improved the prognosis for patients with operable osteosarcoma. The literature is conflicting about which regimen is optimal. The aim of this study was to evaluate the survival outcomes of two cohorts of patients with operable osteosarcoma treated with different perioperative chemotherapy regimens., Methods: This was a retrospective review of patients diagnosed with operable osteosarcoma treated at the Princess Alexandra Hospital from 1986 to 2009. The standard perioperative chemotherapy regimen changed from the modified T10 Rosen protocol to cisplatin/doxorubicin in 1997. Using the Kaplan-Meier method, overall survival (OS) and disease-free survival (DFS) curves were generated for the cisplatin/doxorubicin and the modified T10 Rosen cohorts., Results: Seventy-one patients were identified of whom 63 had potentially curable disease. Of these, 24 received the modified T10 Rosen regimen and 39 received cisplatin/doxorubicin. There was a non-significant trend toward better OS and DFS in the patients who received the modified T10 Rosen protocol., Conclusion: The trend toward poorer survival in the cisplatin/doxorubicin cohort, in combination with current evidence, has prompted our institution to change its practice., (© 2014 Commonwealth of Australia; Asia-Pacific Journal of Clinical Oncology © 2014 Wiley Publishing Asia Pty Ltd.)

To investigate health professionals' perspectives about factors that impede or facilitate cancer care for Indigenous people. Semi-structured interviews with 22 health professionals involved in Indigenous cancer care. Data were interpreted using an inductive thematic analysis approach. Participants presented their perspectives on a number of barriers and enablers to Indigenous cancer care. Barriers were related to challenges with communication, the health system and coordination of care, issues around individual and community priorities and views of cancer treatment and health professional judgement. Enablers to cancer care were related to the importance of trust and rapport as well as health care system and support factors. The findings highlighted the need for recording of Indigenous status in medical records and a coordinated approach to the provision of evidence-based and culturally appropriate cancer care. This could go some way to improving Indigenous patient's engagement with tertiary cancer care services., (© 2016 John Wiley & Sons Ltd.)
