The impact of a multispecialty operative team on colorectal cancer surgery: A retrospective study from a would-be medical center in Taiwan

Abstract

Some studies showed that when distant metastasis or locally advanced tumors were observed, the participation of 2 or more operating surgeons (combined surgery) in the operation could improve the prognosis of patients. The multispecialty operative team would perform combined surgery in colon cancer patients with some complications since 2015.The goal of this study is to confirm performing combined surgery would improve the outcomes of colon cancer patients.A retrospective observational study was conducted, which involved all colon cancer patients between November 2015 and December 2019 at one would-be medical center. Patients were divided into 3 cohorts: those with complicated cases and had combined surgery (C_2S), those with complicated cases and had surgery performed by a single surgeon (C_1S), and those with uncomplicated cases and had surgery performed by a single surgeon (NC_1S). Overall survival and disease-free survival were compared among the 3 groups.A total of 296 colon cancer patients during the study period. Among them, 35 were C_2S, 87 were C_1S, and 174 were NC_1S. Patients in the NC_1S group had significantly higher 12-, 24-, and 36-month OS rates compared to those in the C_1S group (P < .01). In contrast, there was no significant difference in overall survival among patients in the NC_1S and C_2S group (P =.15).The quality of surgery must be impact the prognosis, especially in the individual who was complicated case, the survival in patients who had surgery performed by multispecialty operative team would be improved.Abbreviations: C_1S = patients with complicated cases and had surgery performed by a single surgeon, C_2S = patients with complicated cases and had combined surgery, CRC = colorectal cancer, CI = confidence interval, CT = computed tomography, DFS = disease-free survival, ELN = examined lymph node, HR = hazard ratio, LOS = length of stay, mCRC = metastatic colorectal cancer, NC_1S = patients with uncomplicated cases and had surgery performed by a single surgeon, OS = overall survival, R0 = resection for cure, SD = standard deviation, TCRD = Taiwan Cancer Registry Database.
