TL;DR
The analysis of T4 tumors without distant metastases or serosal penetration showed a significant correlation between the percentage of patients treated by R0 resection and long-term survival in the different participating institutions.
Abstract
Between 1984 and 1986, 2341 patients with colorectal carcinoma from 7 German institutions entered the colorectal carcinoma study group (SGCRC). In 197 of 2053 patients with radical resections, the operation was extended by multivisceral resection. The two groups of patients were comparable in age, preoperative risk factors, postoperative morbidity, and mortality. Long-term results showed no statistically significant difference in survival according to the 5-year survival rates, calculated by the actuarial method when curative resections in UICC stage II and III were compared. After curative resection (R0), the presence or absence of intraoperative tumor-cell dissemination could be identified as a significant prognostic factor. The analysis of T4 tumors without distant metastases or serosal penetration showed a significant correlation between the percentage of patients treated by R0 resection and long-term survival in the different participating institutions.
