Introduction
Active surveillance (AS) seems to be a cost-effective strategy. However, most publications are based on simulation models of theoretical cohorts, and long-term implications are not usually considered.
Objective
To assess the real cost differences of two cohorts of men with low-risk prostate cancer (PCa) treated with AS or laparoscopic radical prostatectomy (LRP) in a public health system.
Materials and methods
Patients diagnosed from 2005 to 2009 were included in an AS program (Group 1) or treated with LRP at diagnosis (Group 2), with a minimum follow-up of 5 years. Actual costs for each patient were calculated on an individual basis: Group 1: semiannual PSA measurements and repeat biopsies are scheduled every 1–3 years. Costs of outpatient clinic visits were calculated, as well as all tests required for monitoring or active treatment. Group 2: costs of the procedure, emergency visits, re-admissions and outpatient clinic visits were calculated, as well as costs of oncological salvage therapies or functional surgical procedures.
Results
Out of 151 men diagnosed with low-risk PC, 54 (35.8%) were included in an AS (Group 1) and 97 (64.2%) were submitted to LRP (Group 2). Mean follow-up for both groups was 6.5 years (SD 1.8) and 6.7 years (SD 1.4), respectively, p = 0.49. Group 1 had a total cost per patient of 2970.47€. Group 2 had a total cost per patient of 5694.06€.
Conclusions
AS was associated with cost-saving over LRP. This cost reduction of AS in the management of low-risk PCa is based on the accounting of real costs of individual patients and confirms previously published estimation-based reports.
