Prostate cancer (PC) treatment is rapidly evolving with new modalities providing more personalized, effective, and increasingly costly options. Several new treatments for non-metastatic castrate-resistant prostate cancer (NM-CRPC), including immunotherapies, antiandrogens, bone-targeted agents, and androgen-receptor targeted agents, have been tested or are currently being tested in clinical trials, all aiming to prolong metastasis-free survival. Although current Canadian and US guidelines do not recommend systemic chemotherapy or immunotherapy for NM-CRPC, patients are encouraged to participate in clinical trials.
Information regarding the current incidence, prevalence and cost of treatment of NM-CRPC and more advanced stages is currently lacking in Canada. This information is highly important for Canadian policymakers facing reimbursement decisions for new drug and non-drug health technologies. Therefore, more up-to-date and robust epidemiologic and economic data concerning NM-CRPC and advanced PC are needed to guide future research and policy decision-making
Study Design & Objectives
This is a three–project retrospective study to obtain comprehensive data on the epidemiology and health care costs of males with NM-CRPC using data from cancer registries, administrative health care databases, and PC clinics in two Canadian provinces, Ontario and Quebec. The study will also identify the pathways leading to NM-CRPC and estimate transition probabilities from previous health states and to subsequent ones. Our specific objectives are to:
- Obtain current prevalence, incidence and survival probability estimates of PC stratified by age, year of diagnosis, and stage of diagnosis (Project 1);
- Identify pathways leading to and factors associated with developing NM-CRPC using information from patient medical records at PC clinics (Project 2);
- Estimate annual incidence and prevalence of NM-CRPC, using administrative data (Project 3);
- Estimate stratified probability of developing NM-CRPC and transition probabilities that characterize the prognosis from NM-CRPC to metastasis and end-of-life (Projects 2 & 3);
- Estimate health care resource use and costs of PC recurrence from NM-CRPC to metastasis and death (Project 3).
Currently, projects 1 and 2 are underway.
