以往临床医师常因不能肯定那些肿瘤仍局限于肠壁而不愿采用局部治疗。1973年法国Papillon首先对直肠癌开展腔内接触放疗。此后,他的成功经验促进了对仔细选择的直肠癌患者采用接触放疗。本文回顾性分析了Cleve1and诊所1973～1984年对62例直肠癌患者单独应用腔内接触放疗作为治疗措施的效果,其中16例在作肿瘤切除活检后进行接触放疗。 In the past, clinicians often refused to use topical therapy because they were not sure that those tumors were still confined to the intestinal wall. In 1973, Papillon of France first performed intraluminal contact radiotherapy for rectal cancer. Since then, his successful experience has promoted the use of contact radiotherapy in patients with carefully selected rectal cancer. This article retrospectively analyzed the results of the treatment of 62 patients with rectal cancer using the intracavity radiotherapy alone as a therapeutic measure from 1973 to 1984 in the Cleve1and Clinic. Among them, 16 patients were treated with radiotherapy after tumor biopsy.
