本文报告直肠癌术前放疗72例与单纯手术治疗42例对比观察。术前放疗可减轻以至消除临床症状,可使瘤体缩小(其缩小率与放射剂量密切相关),而提高手术切除率及根治性切除率,相应地提高了根治术后生存率。从而肯定了直肠癌术前放疗的临床价值。
This article reports 72 cases of preoperative radiotherapy for rectal cancer compared with 42 cases treated with surgery alone. Preoperative radiotherapy can reduce or even eliminate clinical symptoms, make the tumor shrink (the rate of reduction is closely related to radiation dose), and improve the surgical resection rate and radical resection rate, and accordingly improve the survival rate after radical resection. This confirmed the clinical value of preoperative radiotherapy for rectal cancer.
