title: A worse prognosis for men with testicular atrophy at therapeutic orchiectomy for prostate carcinoma.
abstract: BACKGROUND
  The significance of testicular atrophy at the time of therapeutic orchiectomy for prostate carcinoma has not been examined even though pretreatment hypogonadism has been associated with poor prognosis during chemical androgen ablation for these tumors.
  
  
  METHODS
  Survival after therapeutic orchiectomy was determined for 78 men with prostate carcinoma and related to the histologic severity of testicular atrophy. Included in analysis were the presence or absence of prior radiation therapy, tumor grade and stage at diagnosis, host age, obesity, and smoking habits.
  
  
  RESULTS
  Among 35 men who underwent therapeutic orchiectomy for progressive disease after primary radiation therapy to the prostate bed, the 25 men with testicular atrophy had worse 5-year, tumor specific, postorchiectomy survival than the 10 men without testicular atrophy (30% vs. 89%) (P=0.02). These 25 men had tumors of more advanced stage and greater undifferentiation at the time of diagnosis an average of 45 months before orchiectomy, but neither characteristic was related to postorchiectomy survival. Among 25 men with Stage D2 disease (American Urologic Association staging system) with orchiectomy as the primary treatment, the 7 men with testicular atrophy more often had undifferentiated tumors and had lower 2-year tumor specific survival than the 18 men without atrophy (43% vs. 72% ) (P > 0.10).
  
  
  CONCLUSIONS
  Testicular atrophy at the time of therapeutic orchiectomy for prostate carcinoma is associated with poor postorchiectomy prognosis in men with prior prostate bed radiation therapy and perhaps in men without prior radiation. The association may reflect a high frequency of inherently more aggressive tumors (often relatively nonandrogen-dependent) among those tumors that are progressing in hypogonadal men.
