ДИСТАНЦИОННАЯ ЛУЧЕВАЯ ТЕРАПИЯ И ДЛИТЕЛЬНАЯ ГОРМОНОТЕРАПИЯ У БОЛЬНЫХ РАКОМ ПРЕДСТАТЕЛЬНОЙ ЖЕЛЕЗЫ

The authors describe their experience in treating patients with prostate cancer (PC). The data of 68 patients undergoing beam therapy in combination with long-term hormonal therapy are restrospectively analyzed. The patients mainly present with locally advanced tumors. Radiotherapy was performed with a cumulative focal dose of as high as 70 Gy; hormonal therapy involved orchiectomy or long-term adjuvant therapy with luteinizing hormone releasing-hormone analogues for 36 months. Five-year outcomes were estimated; relapse-free and biochemical progression-free survival rates were 88.9 ± 4.9 and 89.4 ± 5.3%, respectively. Early and late radiation damages were also evaluated: the rate of grades 2 and 3 acute radiation-induced urinary tract lesions was 64.3 and 3.6%, respectively; that of grades 1 and 2 gastrointestinal lesions was 26.8 and 7.1%; and that of grade 2 late lesions was not greater than 1.5%.
