METHODOLOGY:
Recent evidence suggested that in men with advanced prostate cancer, local therapy with radical prostatectomy or radiation may improve survival outcomes; however, data on the long-term side effects from these local options were limited.
The retrospective cohort included 5502 men (mean age, 68 years) diagnosed with advanced (T4, N1, and/or M1) prostate cancer.
A total of 1705 men (31%) received initial local treatment, consisting of radical prostatectomy, (55%), radiation (39%), or both (5.6%), while 3797 (69%) opted for initial nonlocal treatment (hormone therapy, chemotherapy, or both).
The main outcomes were treatment-related adverse effects, including GI, chronic pain, sexual dysfunction, and urinary symptoms, assessed at three timepoints after initial treatment — up to 1 year, between 1 and 2 years, and between 2 and 5 years.
TAKEAWAY:
Overall, 916 men (75%) who had initial local treatment and 897 men (67%) with initial nonlocal therapy reported at least one adverse condition up to 5 years after initial treatment.
In the first year after initial treatment, local therapy was associated with a higher prevalence of GI (9% vs 3%), pain (60% vs 38%), sexual (37% vs 8%), and urinary (46.5% vs 18%) conditions. Men receiving local therapy were more likely to experience GI (adjusted odds ratio [aOR], 4.08), pain (aOR, 1.57), sexual (aOR, 2.96), and urinary (aOR, 2.25) conditions.
Between 2 and 5 years after local therapy, certain conditions remained more prevalent — 7.8% vs 4.2% for GI, 40% vs 13% for sexual, and 40.5% vs 26% for urinary issues. Men receiving local vs nonlocal therapy were more likely to experience GI (aOR, 2.39), sexual (aOR, 3.36), and urinary (aOR, 1.39) issues over the long term.
The researchers found no difference in the prevalence of constitutional conditions such as hot flashes (36.5% vs 34.4%) in the first year following initial local or nonlocal therapy. However, local treatment followed by any secondary treatment was associated with a higher likelihood of developing constitutional conditions at 1-2 years (aOR, 1.50) and 2-5 years (aOR, 1.78) after initial treatment.
IN PRACTICE:
“These results suggest that patients and clinicians should consider the adverse effects of local treatment” alongside the potential for enhanced survival when making treatment decisions in the setting of advanced prostate cancer, the authors explained. Careful informed decision-making by both patients and practitioners is especially important because “there are currently no established guidelines regarding the use of local treatment among men with advanced prostate cancer.”
SOURCE:
The study, with first author Saira Khan, PhD, MPH, Washington University School of Medicine in St. Louis, Missouri, was published online in JAMA Network Open.
LIMITATIONS:
The authors noted that the study was limited by its retrospective design. Men who received local treatment were, on average, younger; older or lesser healthy patients who received local treatment may experience worse adverse effects than observed in the study. The study was limited to US veterans.
DISCLOSURES:
The study was supported by a grant from the US Department of Defense. The authors have no relevant disclosures.
