About

The purpose of this study was to identify the prognostic factors of affecting pT4bN0M0 colorectal cancer patients, so as to better stratify the prognostic differences among patients with the same stage.

Full description

Patients with pT4b stage colorectal cancer (CRC) are a complex and special group due to the diversity of infiltrated organs, patients with the same stage often have different prognosis after multivisceral resection (MVR), some important prognostic factors have not been deeply explored, and additional prognostic factors are needed to improve the survival assessment of these patients. In this study, investigators attempted to evaluate the prognostic factors of pT4bN0M0 colorectal cancer, and then stratify the prognosis of such patients to distinguish the survival differences among different patients.

This study was a multicenter retrospective cohort study based on a multicenter database which contained hospitalization.The prognostic factors of pT4bN0M0 colorectal cancer patients were analyzed, and the prognostic grading system was constructed to accurately stratify the survival of pT4bN0M0 patients.
