Principal component analysis of variables with p values <0.200 in univariable logistic regression analysis demonstrated two-sided factor correlations R > [absolute value of 0.500] for age at operation of the primary colorectal tumor and age at liver resection in years (R=0.979), localization of the primary tumor in the colon sigmoideum (yes/no) and the rectum (yes/no) (R=0.522), UICC staging of the primary tumor and pN staging of the primary tumor (R=0.592), UICC staging of the primary tumor and the M1 stage of the primary tumor (yes/no) (R=0.761), the weight of resected liver specimen in kg, and the size of the largest metastasis in mm (R=0.584).
These results lead to the decision to include the variables age at resection of liver metastases, localization of the primary tumor in the colon sigmoideum (yes/no), UICC staging of the primary tumor, and the size of the largest metastasis in mm into multivariable logistic regression analysis and to exclude the variables age at resection of primary tumor, localization of the primary tumor in the rectum, pN staging of the primary tumor, M1 stage of the primary tumor (yes/no), and the weight of resected liver specimen (kg).
