先前的流行病学研究表明,有过敏史的人患结直肠癌及其他恶性肿瘤的风险较低。为了确定直肠癌患者的过敏与淋巴结转移之间的关系,研究者纳入了2003年1月至2011年6月期间入院的直肠腺癌患者。整理分析其临床、实验室和病理参数,并以多变量logistic回归模型确定相关性。此外,研究者还对其过敏性药物进行了亚组分析。结果显示,在469例 Previous epidemiological studies have shown that people with a history of allergies have a lower risk of developing colorectal cancer and other malignancies. To determine the association between allergy and lymph node metastasis in patients with rectal cancer, the investigators enrolled patients with rectal adenocarcinoma admitted between January 2003 and June 2011. The clinical, laboratory and pathological parameters were analyzed and the correlations were determined by multivariable logistic regression model. In addition, the researchers also conducted a subgroup analysis of their allergic drugs. The results showed that in 469 cases
