Objective: To describe the management and outcomes of a population-based cohort of patients with pancreatic cancer treated with chemotherapy or radiotherapy in Victoria, Australia.
Design, setting and patients: Questionnaire-based study of patients diagnosed with pancreatic cancer during 2002-2003 in Victoria who were retrospectively identified from the Victorian Cancer Registry and followed up for a minimum of 5 years.
Main outcome measures: Reported treatment, referral patterns and survival rates.
Results: 1044 patients with pancreatic cancer were identified, of whom 927 were eligible for the study. Completed questionnaires were obtained for 831 eligible patients (response rate, 89.6%) and data for 66 patients with tumours of the ampulla of Vater and neuroendocrine tumours were excluded. Of the remaining 765 patients, 6.5% were managed in multimodality clinics. Chemotherapy was considered for 413 patients and radiotherapy was considered for 162. One-third of the cohort (275 patients) received chemotherapy, most commonly as palliative treatment (185). Single-agent gemcitabine was the most common palliative treatment (154), and was associated with a median overall survival of 6.6 months. Radiotherapy was used in 119 patients (15.6% of the cohort) - it was used alone or with chemotherapy, as postoperative adjuvant treatment, as potentially curative radical treatment, or as palliative treatment. For 45 patients with locally advanced disease who were treated with chemoradiation as radical treatment, median overall survival was 13.1 months.
Conclusions: There appears to be under-referral of patients to medical and radiation oncologists. Median survival of patients treated with radical chemoradiation or palliative chemotherapy is consistent with clinical trial data, but outcomes for patients in our cohort were generally poor. Development and implementation of treatment guidelines may result in improved outcomes.
