Interviews were obtained with 106 patients with adenocarcinoma of the renal parenchyma, 33 patients with carcinoma of the renal pelvis and 139 individually matched control patients. Comparison of the cancer patients with the control patients showed no evidence of a positive association between either type of renal cancer and coffee or animal protein consumption. Carcinoma of the renal pelvis was associated positively with cigareete consumption (relative risk estimate 1-8) and the daily consumption of analgesic tablets was more frequent in patients with cancer of the renal parenchyma than in their matched controls (14-2% compared with 1-9%,P less than 0.005). It appeared likely that the latter relationship was non-causal.
对106例肾实质腺癌患者、33例肾盂癌患者和139例个体匹配的对照患者进行了访谈。癌症患者与对照患者的比较显示,没有证据表明任何一种类型的肾癌与咖啡或动物蛋白摄入之间存在正相关。肾盂癌与吸烟呈正相关(相对风险估计值为1.8),肾实质癌患者每日服用止痛片的频率高于其匹配的对照组(分别为14.2%和1.9%,P<0.005)。后一种关系似乎并非因果关系。
