论文摘要
结直肠癌是指从牙齿线到直肠结肠的结，这是消化道中最常见的恶性肿瘤之一。结直肠癌的治疗是有争议的，因此了解大肠癌的危险因素和存活因子对于诊断患者具有重要意义。这项研究对SEER数据库进行了结直肠癌的患者。通过结合主成分分析和竞争风险模型来分析影响结直肠癌患者存活的因素，并通过将主成分分析和线性回归结合分析患者的生存时间。最后，预测数据。结果表明，主成分分析可以有效地减少变量的数量，竞争风险模型和线性回归模型的组合可以有效地分析和预测数据。
Colorectal cancer refers to the cancer from the dentate line to the junction of rectosigmoid colon, which is one of the most common malignant tumors of the digestive tract. The treatment of colorectal cancer is controversial, so understanding the risk factors and survival factors of colorectal cancer is of great significance for the diagnosis of patients. This study sampled patients with colorectal cancer from the SEER database. The factors affecting the survival of colorectal cancer patients were analysed by combining principal component analysis and competitive risk model, and the survival time of patients was analysed by combining principal component analysis and linear regression. Finally, the data were predicted. The results show that principal component analysis can effectively reduce the number of variables, and the combination of competitive risk model and linear regression model can effectively analyse and predict the data.
