Breakthrough in Prostate Cancer Treatment: Improved Survival Rates for Intermediate-Risk Patients

In a significant advancement in the fight against prostate cancer, a recent study presented at the 2025 Genitourinary Cancers Symposium has revealed promising results for patients with intermediate-risk prostate cancer. The research highlights the efficacy of external beam radiation therapy (EBRT) with or without short-term neoadjuvant androgen deprivation therapy (STAD) in improving long-term survival rates.

Improved Survival Outcomes

The study, which followed patients for a median of 12 years and up to 19.8 years, demonstrated that both treatment regimens – EBRT alone and EBRT combined with STAD – led to impressive survival statistics. The 15-year prostate cancer-specific survival (PCSS) rate was a remarkable 91% for both groups, with no significant difference between them (P = .67). Additionally, the 15-year overall survival (OS) rates were 53% for the STAD plus EBRT group and 51% for the EBRT alone group (P = .82).

Metastasis-Free Survival and Biochemical Failure

The metastasis-free survival (MFS) rate after 15 years was 85% for patients receiving STAD plus EBRT and 83% for those receiving EBRT alone. Furthermore, the 15-year freedom from biochemical failure (FFBF) rates were 52% and 49% in each respective arm, indicating a slight but not statistically significant advantage for the combined therapy.

Comparative Studies

Previous studies published in JAMA and the New England Journal of Medicine support these findings. For instance, a study in JAMA showed that patients with localized, unfavorable-risk prostate cancer had a 94% 10-year PCSS rate with STAD plus EBRT, compared to 81% with EBRT alone (P = .02). Another study in the New England Journal of Medicine found that patients receiving EBRT with STAD for 4 months had a 97% 10-year PCSS rate, versus 89% for those receiving EBRT alone (P = .001).

Clinical Implications

These results have significant clinical implications, suggesting that both treatment approaches can be effective for intermediate-risk prostate cancer patients. However, the study also noted that patients undergoing STAD experienced more adverse factors compared to those receiving EBRT alone.

Early Detection and Personalized Treatment

Early detection remains a crucial factor in the successful treatment of prostate cancer. Advances in diagnostic techniques and imaging, as seen at institutions like the Clínica Universidad de Navarra in Spain, enable early diagnosis and personalized treatment plans. These advancements have contributed to high survival rates, with some centers reporting nearly 100% 10-year survival rates for localized prostate cancer.

Conclusion

The latest findings from the 2025 Genitourinary Cancers Symposium offer hope and improved treatment options for men with intermediate-risk prostate cancer. As medical research continues to evolve, the emphasis on early detection, personalized medicine, and innovative treatment regimens is expected to further enhance survival outcomes for prostate cancer patients. For expats in Spain, accessing state-of-the-art diagnostic and therapeutic facilities, such as those available at the Clínica Universidad de Navarra, can be a significant advantage in managing this condition.
