对７１例直肠粘液癌和４４４例同期收治的直肠非粘液癌进行了比较研究。对性别，ＤＵＫＥＳ分期，手术方法，局部复发和远处转移以及生存率等进行了统计学分析。结果表明在粘液癌病例中，青年患者的比率明显高于非粘液癌。粘液癌中的进展期肿瘤所占比率亦比非粘液癌高，但进一步控制条件分析发现，这种分期差异仅存在于青年患者之中，而在＞４０岁的患者中这种差异并不明显。本资料显示粘液病的局部复发和远处转移均高于非粘液癌，但无统计学意义。经寿命表分析和对数秩检验证明，粘液癌经外科手术治疗后的累积生存率较非粘液癌为低，并且这种差异在青年患者中非常明显。
A comparative study of 71 cases of rectal mucinous carcinoma and 444 cases of rectal non-mucinous carcinoma treated at the same time. Gender, DUKES staging, surgical methods, local recurrence and distant metastasis, and survival rates were statistically analyzed. The results showed that the rate of young patients in mucinous cancer cases was significantly higher than that of non-mucinous cancer. The proportion of advanced tumors in mucinous carcinomas is also higher than that of non-mucinous carcinomas, but further controlled condition analysis found that this staging difference is only present in young patients, whereas this difference is not significant in >40 year old patients. . This data showed that both local recurrence and distant metastasis of mucinous disease were higher than those of non-mucinous cancer, but not statistically significant. Life table analysis and log-rank test showed that the cumulative survival rate of mucinous cancer after surgical treatment was lower than that of non-mucinous cancer, and this difference was very obvious in young patients.
