本文作者分析了结直肠癌单纯切除术后未行其它辅助治疗患者5年内复发情况及预后因素。 病例为日本140家医院1984年2月至1985年12月单纯手术切除治疗的结直肠癌患者。对分析对象每年随访1次共5年,均需符合下列标准:结肠或直肠癌诊断旨定,手术时年龄小于75岁,手术前一般实验室检查无重要异常发现,无严重并发症,术后未进行其它抗癌治疗。其中结肠癌279例,男146例.女133例,平均年龄61岁;直肠癌29例,男176例,女117例,平均年龄60岁。单纯手术切除后5年复发率用Cox比例风险模型进行多变量分析。 结肠癌和直肠癌患者单纯手术切除治疗后5年生
The authors analyzed the recurrence and prognostic factors within 5 years of patients who had not undergone other adjuvant therapy after simple resection of colorectal cancer. Cases were colorectal cancer patients who were treated with surgery in 140 hospitals in Japan from February 1984 to December 1985. For the subjects to be followed up once every year for 5 years, they all need to meet the following criteria: The diagnosis of colon or rectal cancer was made. The age at the time of surgery was less than 75 years old. There was no major abnormality in the laboratory tests before surgery and there were no serious complications. No other anticancer treatment was performed. There were 279 cases of colon cancer, 146 males and 133 females, with an average age of 61 years; 29 cases of rectal cancer, 176 males and 117 females, with an average age of 60 years. The 5-year recurrence rate after surgical resection alone was multivariately analyzed using the Cox proportional hazards model. 5-year-old patients with colon and rectal cancer after surgical resection alone
