Description

Rees et al reported scores for predicting survival following resection of hepatic metastases from a colorectal cancer. One score gives a preoperative assessment and the second postoperative. The authors are from North Hampshire Hospital in Basingstoke and Imperial College London.


Patient selection: resectable hepatic metastases from a colorectal cancer

 

Outcome: various measures of cancer-specific survival

 

Parameters:

(1) lymph nodes status of primary tumor (N)

(2) differentiation of primary colorectal cancer

(3) CEA level at time of hepatectomy in ng/mL

(4) largest tumor diameter in cm

(5) hepatic resection margin

(6) extrahepatic metastatic disease
