Multidisciplinary team intervention associated with improved survival for patients with colorectal adenocarcinoma with liver or lung metastasis

Background and Objectives: To investigate whether multidisciplinary team (MDT) intervention is associated with improved survival for patients with colorectal adenocarcinoma with liver or lung metastasis (CRA-LLM). Methods: We enrolled 161 consecutive patients with histologically confirmed CRA-LLM at Taipei Medical University-Wan Fang Hospital between January 2007 and December 2017. In total, 75 patients with CRA-LLM received MDT intervention, and 86 patients did not receive MDT intervention. To evaluate prognostic factors for overall death, we performed univariate and multivariate Cox regression analyses of the overall death rate in all patients. Overall survival rates were calculated using the Kaplan-Meier method, and Kaplan-Meier survival curves were compared using the log-rank test (P < .001). Results: A multivariate Cox regression analysis of the overall death rate in patients with CRA-LLM showed that age ≤ 65 years, systemic chemotherapy, curative-intent treatments, and MDT intervention are strong prognostic factors. The adjusted hazard ratio of death risk for age ≤ 65 years, systemic chemotherapy, curative-intent treatments, and MDT intervention were 0.60 (95% confidence interval [CI], 0.40-0.92; P = .019), 0.19 (95% CI, 0.12-0.32; P = .001), 0.25 (95% CI, 0.13-0.50; P = .001), and 0.40 (95% CI, 0.25-0.65; P = .001), respectively. The 3-year overall survival rates in patients with CRA-LLM receiving MDT intervention and not receiving MDT intervention were 48.75% and 24.21%, respectively. Conclusion: MDT intervention is associated with improved survival for patients with CRA-LLM.
