Abstract:
Objective To evaluate the outcome , side effects and prognosis of prostate carcinoma treated with external radiotherapy. Methods From 1990 to 1999, a total of 45 prostate carcinoma patients were treated. Four cases were lost during follow up. Forty one patients underwent orchiectomy before radiation therapy , 29 received orchiectomy combined with hormone treatment. All patients received conventional radiation therapy with a median dose of 68.3 ?Gy (50.4 75.9?Gy), 1.8 2.0?Gy per fraction, five fractions weekly. Results The median follow up duration was 28 months (1 111 months). The overall 5 year survival was 76.4% and the 5 year disease specific survival was 76.5%. In terms of acute GI side effects, the frequencies of Grade Ⅰ, Ⅱ or Ⅲ reactions were 53.5%, 7.0% and 9.3% while Grade Ⅰ or Ⅱ , acute GU side effects were 41.9% and 4.7%, respectively. For the long term deleterious effects,Grade Ⅰ or Ⅱ in GI late complications were 16.7% and 7.1% and the GU late morbidities of Grade Ⅰ,Ⅱ or Ⅲ were 23.8%, 4.8% and 2.4%, respectively. Regional lymph node metastasis was closely correlated with both overall survival (P= 0.002 ) and disease specific survival (P= 0.002 ). Multivariate analysis revealed, only regional lymph node metastasis was of prognostic value to predict the overall survival and disease specific survival. Conclusion The outcome of radiation therapy for patients with T 2 T 4 prostate carcinoma is satisfactory with the side effects tolerable to most patients.
