This is a first report from The Bahamas of management and long-term outcomes in men with non-metastatic prostate cancer treated with radiotherapy, with or without androgen deprivation therapy, from 2004 to 2016.
Patients were characterized by baseline factors, stratified by risk groups using tumor stage (clinical T-stage), prostate-specific antigen (PSA) test result and Gleason grade, and sorted by treatment combinations (by radiation volume and use of androgen deprivation).
Overall, 205/216 men were Afro-Caribbean. Median age was 66. There were 18 low-, 77 intermediate-, and 121 high-risk patients, treated with prostate-only versus pelvis plus prostate radiotherapy, many receiving 2 years of androgen suppression. Time to commence radiation was about 6 months from initial diagnosis. In those not relapsing, global PSA nadir was reached in 4 years and was under 1.0, reduced from a mean at baseline of 31. At 10 years, disease-free experience (32 relapses) was 68% and overall survival was 87%, although only 2/12 deaths were related to prostate cancer. This experience compares favorably with recently published outcomes from other countries using very similar treatments.
This study establishes benchmark statistics from diagnosis to long-term follow-up. Outcomes in Bahamian men are consistent with expectations from risk-stratified guidelines followed in developed countries.
