title: Radical radiotherapy for localized prostate cancer in elderly.
abstract: BACKGROUND
  Prostate cancer is an age related neoplasm, with high incidence in the group of elderly man. The correct management must to be balanced between the benefits of the treatment and its disadvantages. Radiotherapy as definitive treatment is commonly reserved for older patients and patients with high surgical risk and is widely used as a treatment of choice.
  
  
  OBJECTIVE
  The aim of this study was to determine the role of radical radiotherapy for localized prostate carcinoma in patients 70 years age or older concerning treatment morbidity, local control, disease free and overall survival.
  
  
  METHODS
  A clinical prospective non-randomized study was performed including 103 elderly patients with an age 70 or above, between January 1991 and April 2005, at the Institute for Oncology and Radiology of Serbia. Median age of patients was 74,89 years (range 70- 80 years). Stage distribution was as follows: stage A--3 patients (2.9%), stage B--69 patients (67%) and stage C--31 patients (30.1%). Out of 103 patients, initial PSA value was noted in 87 patients. The mean value of initial PSA was 18,06 ng/ml. Radical radiotherapy was conducted on megavoltage linear accelerators with high energy photons (10, 18 MeV) and total tumor dose of 65 Gy.
  
  
  RESULTS
  Low grade acute complications were registered in 70 patients (65%). Mean follow up time was 40, 13 months. The disease outcome at the last follow up show that 79 patients (76.7%) had no evidence of disease and 24 patients (23.3%) relapsed. Overall survival rates were 65, 29% and 44, 52% and disease free survival 66, 59% and 63, 26% at 5 and 10 years. Disease specific survival was at 5 and 10 years 73,32% and 65, 42% respectively. Late sequelas (gradus I and II) are registered in 22 patients (21.36%), out of 103.
  
  
  CONCLUSIONS
  Radical radiotherapy for localized carcinoma of the prostate is effective treatment option in elderly patients with good local control, present treatment tolerance providing good quality of life and long-term cure.
