[The standard to indicate operations for esophageal cancer based upon quantitative evaluation of physical conditions].
Based upon quantitative evaluation of the physical conditions, we had established the standard to indicate operations for esophageal cancer. The standard consisted of functions of important organs, organ function index and host defense index. In the present study, operative death was estimated by applying the standard. Retrospective study was performed in 35 resected patients from 1981 to 1985 while prospective study was in 24 resected patients from 1986 to 1987. Operative methods were classified into three levels according to operative stress: One stage, two stages and no operation. The estimation of operative death was done on the assumption that the patient dies if performed operation is over one level more excessive than operation indicated by the standard. Retrospective study showed that 9 of 10 patients with operative death and 24 of 25 without it were estimated, percent of cases correctly estimated being 94.3%. Prospective study also revealed that all of two patients with operative death and 19 of 22 without it were predicted, the percent being 87.5%. From these results, we may conclude that the standard is useful to indicate operations for esophageal cancer.
