Multidisciplinary discussion and management of synchronous colorectal liver metastases: A single center study in China.

Background: The multidisciplinary team (MDT) has been carried out in many large hospitals now. However, given the costs of time and money and with little strong evidence of MDT effectiveness being reported, critiques of MDTs persist.

Aim: To evaluate the effects of MDTs on patients with synchronous colorectal liver metastases and share our opinion on management of synchronous colorectal liver metastases.

Methods: In this study we collected clinical data of patients with synchronous colorectal liver metastases from February 2014 to February 2017 in the Chinese People's Liberation Army General Hospital and subsequently divided them into an MDT+ group and an MDT- group. In total, 93 patients in MDT+ group and 169 patients in MDT- group were included totally.

Results: Statistical increases in the rate of chest computed tomography examination ( = 0.001), abdomen magnetic resonance imaging examination ( = 0.000), and preoperative image staging ( = 0.0000) were observed in patients in MDT+ group. Additionally, the proportion of patients receiving chemotherapy ( = 0.019) and curative resection ( = 0.042) was also higher in MDT+ group. Multivariable analysis showed that the population of patients assessed by MDT meetings had higher 1-year [hazard ratio (HR) = 0.608, 95% confidence interval (CI): 0.398-0.931, = 0.022] and 5-year (HR = 0.694, 95%CI: 0.515-0.937, = 0.017) overall survival.

Conclusion: These results proved that MDT management did bring patients with synchronous colorectal liver metastases more opportunities for comprehensive examination and treatment, resulting in better outcomes.
