✦ Synopsis
BACKGROUND.
The significance of testicular atrophy at the time of therapeutic orchiectomy for prostate carcinoma has not been examined even though hypogonadism may occur after prostate bed radiation therapy for these tumors, may itself be symptomatic, and also may be associated with poor tumor prognosis.
METHODS.
Therapeutic orchiectomy specimens from 78 men with prostate carcinoma and no preceding hormonal therapy were evaluated histologically for atrophy. Observations were related to prior radiation therapy, tumor grade and stage diagnosis, host age, obesity, and smoking habits.
RESULTS.
Thirty-five men who previously received radiation therapy to the prostate bed had testicular atrophy more frequently than 43 men without prior radiation (71% vs. 28%) (P Ͻ 0.001). In men without prior radiation, atrophy was less common in specimens from those age Ͻ 70 years than in specimens from men age Ͼ 70 years (7% vs. 38%) (P Ͻ 0.04). In men with prior radiation, prominent atrophy occurred with similar frequency in specimens from both younger and older men, and was more frequent in specimens obtained within 3 years after radiation therapy than in specimens obtained after longer postradiation intervals (89% vs. 53%) (P Ͻ 0.001).
CONCLUSIONS.
Testicular atrophy at the time of therapeutic orchiectomy for men with prostate carcinoma is much more common in patients with prior prostate bed radiation therapy. Available evidence suggests that this association may reflect both radiation-induced testicular injury and more frequent early tumor recurrence in men with atrophy preceding their radiation therapy.
