Prostate cancer treatment side effects differ by method

Research indicates that the specific treatment path chosen by men diagnosed with prostate cancer influences both the type of complications they face and their mortality risk in the years following therapy. The findings highlight distinct profiles for surgical intervention versus radiation exposure.

Study methodology and scope

Investigators from the State University of New York analyzed medical records for more than 20,000 men who received either surgery or radiation. These patients were followed for approximately five years to track long-term outcomes.

The study focused on early-stage prostate cancer, defined as disease confined to the gland before spreading elsewhere. Two primary options exist for these cases: radical prostatectomy, which involves removing the prostate, and radiation therapy, which uses high-energy beams to target cancer cells without surgical incision.

Comparative complication rates

Data revealed significant differences in side effect prevalence between the two groups. Among men who underwent surgery, 29 percent experienced urinary incontinence, compared to just 6 percent of those treated with radiation. Additionally, roughly one-third of the surgical cohort suffered from erectile dysfunction.

Conversely, patients receiving radiation therapy showed higher susceptibility to other urological issues. This group faced increased risks of urinary retention, bladder inflammation, and hematuria, or blood in the urine.

Mortality trends and limitations

The analysis recorded higher all-cause mortality rates among the radiation group. Approximately 8 percent of these patients died during the follow-up period, whereas the figure stood at 6.5 percent for those who had surgery. The study associated radiation treatment with a 45 percent increase in the overall death rate.

Dr. Jeffrey Weiss, a professor of urology and the study’s lead author, emphasized that these observations do not prove causation. Because the research was observational, it cannot confirm that radiation directly caused the elevated mortality figures. He noted that both treatments impact urinary and sexual function, underscoring the necessity for doctors to discuss risks, benefits, and side effects with patients before decision-making.

Researchers called for further studies to better understand the long-term effects of different therapies, particularly regarding survival rates and the recurrence of prostate cancer.
