最近英国Royal Marsden NHS Trust(RMT)在前列腺癌适形治疗中引进了特制盆腔固定系统(IMS)以提高摆位准确性,该研究通过一组随机交叉自身配对试验,前瞻性评价IMS与CTP(常规治疗摆位)相比较的结果。 1997年8月～1998年8月,RMT收治30例前列腺癌,中位年龄68岁(52～81岁),所有病例经组织学检查证实为临床T_1-T_3期,没有远处转移,中位PSA13ng/ml(5～87ng/ml),中位Gleason分级 Recently, the Royal Marsden NHS Trust (RMT) in the United Kingdom introduced a special pelvic fixation system (IMS) to improve the accuracy of the positioning in the treatment of prostate cancer conformation. This study evaluated the IMS and CTP prospectively through a set of random cross-matching experiments. The results of the comparison of conventional treatment placements). From August 1997 to August 1998, 30 cases of prostate cancer were treated with RMT. The median age was 68 years (52 to 81 years old). All cases were confirmed by clinical histological examination as clinical T_1-T_3 stage, with no distant metastasis. PSA13 ng/ml (5-87 ng/ml), median Gleason grading
