Oesophageal cancer treatment patterns, timeliness of care and outcomes in the Loddon Mallee region of Victoria: A retrospective cohort study.

INTRODUCTION: Few studies have investigated oesophageal cancer care in regional areas. This study aimed to describe treatment patterns for oesophageal cancer in a regional area, and to identify factors associated with radiotherapy utilisation, timeliness of care, and death. METHODS: In a retrospective cohort study, medical records were reviewed to source data on all patients diagnosed with and/or treated for oesophageal cancer at two regional Victorian hospitals over July 2015-June 2018. Cox proportional hazards regression was employed to identify factors associated with time from diagnosis to death while binary logistic regression was used to identify factors associated with radiotherapy utilisation and treatment within 28 days of diagnosis - a time frame derived from the relevant optimal care pathway. RESULTS: Of 95 patients, 72% had radiotherapy, 32% received any treatment within 28 days, and 78% died over a median time of nine months. Odds of not receiving radiotherapy were decreased (odds ratio [OR] = 0.26, 95% confidence interval [CI] = 0.08-0.87) for histology other than adenocarcinoma. Odds of timely care were increased for any palliative radiotherapy (OR = 3.47, 95% CI = 1.15-10.5) and decreased for older age (OR = 0.95, 95% CI = 0.91.0.999). Hazard of death was elevated for stage IV disease (hazard ratio [HR] = 2.73, 95% CI = 1.64-4.54) and reduced for radical intent (HR = 0.27, 95% CI = 0.15-0.48). CONCLUSION: Nearly three-quarters of regional oesophageal cancer patients had radiotherapy while approximately one-third received any treatment within the recommended 28 days. Any palliative radiotherapy and younger age were associated with timely treatment. Future studies could further investigate factors related to timely oesophageal cancer care.

Timeliness of cancer care in a regional Victorian health service: A comparison of high-volume (Lung) and low-volume (oesophagogastric) tumour streams.

BACKGROUND: Timeliness of cancer care is vital for improved survival and quality of life of patients. Service and care centralisation at larger-volume centres has been associated with improved outcomes. However, there is a lack of systematic data on the impact of tumour stream volume on timeliness of care. AIMS: To investigate and compare timeliness of care for lung cancer, a high-volume (more commonly diagnosed) tumour stream, and oesophagogastric (OG) cancer, a low-volume (less commonly diagnosed) tumour stream, at a regional health service in Victoria, Australia. METHODS: A retrospective cohort study comprising random samples of 75 people newly diagnosed with lung cancer (International Classification of Diseases and Related Health Problems-10 [ICD-10] diagnosis codes C34 in the Victorian Cancer Registry [VCR]) and 50 people newly diagnosed with OG cancer (ICD-10 diagnosis codes C15 or C16 in VCR) at one regional Victorian health service between 2016 and 2017. Binary logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for associations between patient factors and suboptimal timeliness of care. RESULTS: In comparison to OG cancer patients, lung cancer patients had reduced odds of suboptimal timeliness of care in reference to times outside OCP for referral to diagnosis (OR [95% CI] = 0.34 [0.14 to 0.83]) but increased odds of suboptimal timeliness for diagnosis to treatment (OR [95% CI] = 2.48 [1.01 to 6.09]). CONCLUSION: In the low-volume OG cancer stream, patients had longer wait times from referral to an MDM, where treatment decisions occur, but shorter time to commencement of first treatment. Conversely in the high-volume lung cancer group, there was delayed initiation of first treatment following presentation at MDM. There is need to explore ways to fast-track MDM presentation and commencement of therapy among people diagnosed with low-volume and high-volume cancers, respectively.
