536例早期前列腺癌患者，经放射性同位素’”1植入，继之用体外放射治疗，治疗后随诊10年，最后找出表明癌瘤已潜在治愈的前列腺特异抗原（n认）的水平至少应达到05edlnl，这与前列腺癌根治术后的水平一样。DeKalh医学中心放射科主任Ch。教授说，这是首次证实前列腺癌放疗后， 536 patients with early-stage prostate cancer were radioisotope ’’1 implanted, followed by external radiation therapy, followed up for 10 years after treatment, and finally found the level of prostate-specific antigen (nP) that indicated that cancer has been potentially cured. Should reach 05 edlnl, which is the same level as after radical prostatectomy. Professor Prof. Ch. Professor of Radiology at DeKalh Medical Center said that this is the first time that prostate cancer has been treated with radiotherapy.
