Background: Patients with locally advanced head and neck squamous cell carcinoma (HNSCC) require multi‐modality treatment. Immune checkpoint inhibitors (ICIs) are now standard of care in management of recurrent/metastatic HNSCC. However, its role in the definitive and neoadjuvant setting remains unclear.Methods: A literature search was conducted that included all articles investigating ICI in untreated locally advanced (LA) HNSCC. Data was extracted and summarised and rated for quality using the Cochrane risk of bias tool.Results: Of 1086 records, 29 met the final inclusion criteria. In both concurrent and neoadjuvant settings, the addition of ICI was safe and did not delay surgery or reduce chemoradiotherapy completion. In the concurrent setting, although ICI use demonstrates objective responses in all published trials, there has not yet been published data to with PFS or OS benefit. In the neoadjuvant setting, combination ICI resulted in superior major pathological response rates compared to ICI monotherapy without a significant increase adverse event profiles, but its value in improving survival is not clear. ICI efficacy appears to be affected by tumour characteristics, in particular PD‐L1 combined positive score, HPV status and the tumour microenvironment.Conclusions: There is significant heterogeneity of ICI use in untreated LA HNSCC with multiple definitive concurrent and neoadjuvant protocols used. Resultantly, conclusions regarding the survival benefits of adding ICI to standard‐of‐care regimens cannot be made. Further trials and translational studies are required to elucidate optimal ICI sequencing in the definitive setting as well as better define populations more suited for neoadjuvant protocols.

Early phase cancer clinical trials (EPCTs) involve experimental drugs being used for the first time in humans. These studies are designed for dose determination and safety, and represent the most time intensive of all clinical trials for both clinicians and patients. We sought to quantify the amount of patient time consumed through EPCT participation. A retrospective audit of patients treated in the EPCT unit at Liverpool Hospital, Sydney was carried out from 2013 to 2023. We defined 'time toxicity' (TT) as a composite measure where time-toxic days were considered days with any health care system contact, including clinic visits, infusions, procedures or blood work. A total of 219 patients across 36 EPCTs were included. The median age was 65 years (range 31-81 years). Patients spent a median of 29% (range 4%-100%) of their days in direct contact with the health care system during their study. Protocol-specified visits accounted for the greatest contribution to total TT in 101 (46%) patients. In 7% (n = 16) of patients, unscheduled visits due to either adverse events or cancer-related symptoms accounted for the greatest TT. TT reduced as patients completed additional cycles of treatment. Patients who completed >10 cycles spent 14% of their days interacting with health care systems compared with 35% for those who completed ≤2 cycles. No statistically significant difference in TT was noted between dose-expansion and dose-escalation studies or trials focusing on immune-oncology versus targeted therapy. Our study is the first to report TT in EPCTs with an extended follow-up. Clinicians should be aware of TT when discussing risks and benefits. TT also may not be the appropriate term when describing the time patients invest during EPCTs. Toxicity implies a negative impact, but for many patients, trial participation would be seen as positive. There should be efforts to streamline health care visits to limit TT in EPCTs.

Sustained elevation in neutrophil‐to‐lymphocyte ratio (NLR) after initial chemoradiotherapy (CRT) has been shown to correlate with worse prognosis in a number of solid organ malignancies. Here, we conducted a retrospective observational cohort study involving six sites across Sydney, Australia, including all patients with unresectable stage III NSCLC treated with CRT and consolidation durvalumab between January 2018 and September 2021. Patients had NLR collected prior to CRT and prior to cycle one of durvalumab. We used an NLR value of 3 to stratify patients into high and low groups. Patients with sustained NLR were defined as those with values ≥3 at both timepoints. A total of 145 patients were included in the study. The median age of patients was 66 years with median follow‐up of 15.1 months. The median PFS was 17.6 months in the pre‐CRT NLR high cohort and not reached (NR) in the pre‐CRT NLR low cohort (HR 1.99; p = 0.01). The median OS was 35.5 months in the high pre‐CRT NLR cohort compared with 42.0 months in the low pre‐CRT NLR cohort (HR 2.62; 95% CI: 1.23–5.56, p < 0.01). Median PFS for sustained NLR elevation was 17.1 months versus NR (HR 1.5; p < 0.01). Pre‐CRT NLR and sustained NLR remained independently prognostic for PFS on multivariate analysis (p = 0.04, p = 0.01) respectively. Pre‐CRT NLR and sustained NLR is associated with worse PFS outcomes in unresectable stage III NSCLC treated with CRT and durvalumab. Pre‐CRT NLR is also associated with worse OS.

Colorectal cancer remains the third most common malignancy in Australia with the peritoneum being the second most common metastatic site. Colorectal peritoneal carcinomatosis (CPC) can be treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy but this is only limited to a small subset of patients. Those with inoperable disease have a particularly poor prognosis. While the ideal systemic regimen has not been defined, 5‐fluorouracil‐based chemotherapy regimens appear to provide overall and progression free survival benefits. The role of targeted agents such as bevacizumab (vascular endothelial growth factor inhibitor) or cetuximab (epidermal growth factor inhibitor) in the setting of CPC is still evolving. Currently, retrospective analyses have shown promising results for the use of bevacizumab in addition to systemic chemotherapy but similar results have not been seen with cetuximab or panitumumab. However, there is significant heterogeneity in the trial data, lack of prospective randomized controlled trials and demonstrated treatment variability based on age and tumour characteristics. This review summarises the current literature in regard to treatment in the unresectable CPC setting as well as discussing issues with the current data and highlighting the need for further trials.

PURPOSE: Although large language models (LLMs) are increasingly used in clinical practice, formal assessments of their quality, accuracy, and effectiveness in medical oncology remain limited. We aimed to evaluate the ability of ChatGPT, an LLM, to generate physician and patient letters from clinical case notes. METHODS: Six oncologists created 29 (four training, 25 final) synthetic oncology case notes. Structured prompts for ChatGPT were iteratively developed using the four training cases; once finalized, 25 physician-directed and patient-directed letters were generated. These underwent evaluation by expert consumers and oncologists for accuracy, relevance, and readability using Likert scales. The patient letters were also assessed with the Patient Education Materials Assessment Tool for Print (PEMAT-P), Flesch Reading Ease, and Simple Measure of Gobbledygook index. RESULTS: Among physician-to-physician letters, 95% (119/125) of oncologists agreed they were accurate, comprehensive, and relevant, with no safety concerns noted. These letters demonstrated precise documentation of history, investigations, and treatment plans and were logically and concisely structured. Patient-directed letters achieved a mean Flesch Reading Ease score of 73.3 (seventh-grade reading level) and a PEMAT-P score above 80%, indicating high understandability. Consumer reviewers found them clear and appropriate for patient communication. Some omissions of details (eg, side effects), stylistic inconsistencies, and repetitive phrasing were identified, although no clinical safety issues emerged. Seventy-two percent (90/125) of consumers expressed willingness to receive artificial intelligence (AI)-generated patient letters. CONCLUSION: ChatGPT, when guided by structured prompts, can generate high-quality letters that align with clinical and patient communication standards. No clinical safety concerns were identified, although addressing occasional omissions and improving natural language flow could enhance their utility in practice. Further studies comparing AI-generated and human-written letters are recommended.

PURPOSE: Mentorship has a positive influence on trainee skills and well-being. A 2022 Pilot Mentorship Program in New South Wales involving 40 participants revealed high burnout rates in Medical Oncology trainees. As part of an Australia-wide inaugural National Oncology Mentorship Program in 2023 (NOMP23), a national survey was undertaken to assess the prevalence of burnout, anxiety, depression, professional fulfilment, and drivers of distress in the Australian medical oncology workforce. METHODS: NOMP23 is a 1-year prospective cohort study that recruited medical oncology trainees and consultants using e-mail correspondence between February and March 2023. Each participant completed a baseline survey which included the Maslach Burnout Index (MBI), Stanford Professional Fulfilment Index, and Patient Health Questionnaire-4 for anxiety and depression. RESULTS: One hundred and twelve participants (56 mentors, 56 mentees) were enrolled in NOMP23, of which 86 (77%) completed the baseline survey. MBI results at baseline demonstrated that 77% of consultants and 82% of trainees experienced burnout in the past 12 months. Professional fulfilment was noted to be <5% in our cohort. Screening rates of anxiety and depression in trainees were 32% and 16%, respectively, compared with 7% and 2% for consultants. When assessing reasons for workplace stress, two thirds stated that heavy patient load contributed to stress, while almost three quarters attributed a heavy administrative load. Lack of supervision was a key stressor for trainees (39%), as was lack of support from the training college (58%). CONCLUSION: Trainees and consultant medical oncologists demonstrate high rates of burnout and low professional fulfilment. The NOMP23 program has identified a number of key stress factors driving burnout and demonstrated concerning levels of anxiety and depression. Ongoing mentorship and other well-being initiatives are needed to address these issues.
