OBJECTIVE: To explore reasons for survival disparities for patients with prostate cancer in the Barwon South West area of Victoria.
DESIGN, SETTING AND PARTICIPANTS: We have described incidence, diagnostics, treatment pathways, and survival for four regions of the Barwon South Western Victoria. Analysis included all newly diagnosed prostate cancer patients from 2009 to 2015 in the Evaluation of Cancer Outcomes Barwon South West Registry. Regions included 1: Queenscliffe 2: Geelong, Colac Otway and Corangamite 3: Moyne, Warrnambool and Southern Grampians and 4: Glenelg. Across the four regions, variables were compared using a chi square statistic or analysis of variance and survival data was assessed with the Kaplan-Meier curves.
MAIN OUTCOME MEASURES: Incidence, treatment pathways and survival for prostate cancer patients.
RESULTS: A total of 1776 patients were diagnosed with prostate cancer from 2009 to 2015 in the Barwon South West area. In regions 1-4, there were 298 (1.04%), 1085 (0.92%), 273 (0.97%) and 120 (1.2%) cases, respectively. There was no significant difference in Gleason score and treatment. The 5-year survival rate was 85%, 76%, 71% and 80%, respectively, as compared with the national average of 95%. PSA scores >20 ng/ml at diagnosis, as a surrogate for high-risk disease, occurred in 23%, 29%, 22% and 21%, respectively (p < 0.01). The proportions presenting with stage IV disease were 17%, 26%, 21% and 6%, respectively (p = 0.10).
CONCLUSION: Men diagnosed with prostate cancer in South West Victoria have a considerably lower 5-year survival compared with the national average with later disease at presentation in some areas.
