Simultaneous resection of colorectal cancer with synchronous liver metastases: A survey-based analysis.

e15073 Background: Patients with colorectal cancer and synchronous liver metastases may undergo simultaneous or staged resection. Methods: We electronically surveyed members of the Society of Surgical Oncology, Canadian Hepato-Pancreato-Biliary Association and the College of Physicians and Surgeons of Ontario with a pilot-tested questionnaire. Four clinical scenarios were presented. Perceived outcomes of and barriers to simultaneous resection were assessed on a Likert scale using Mann-Whitney U and Chi-square tests for ordinal and categorical variables, respectively. We compared results between general and hepatobiliary surgeons. We sought to determine surgeons’ attitudes and perceived barriers to simultaneous resection and compare them between general and hepatobiliary surgeons. Results: The response rate of 20% (234/1166) included 50 general and 134 hepatobiliary surgeons. A high likelihood score (Likert ≥5-7) for support of simultaneous resection among general and hepatobiliary surgeons, respectively, included the following: for minor liver and low complexity colon, 83% and 98% (p < 0.001); for minor liver and rectal resection, 57% and 73% (p = 0.042); for complex liver and low complexity colon resection, 26% and 24% (p = 0.858); and, for complex liver and rectal resection, 11% and 7.0% (p = 0.436). Among hepatobiliary surgeons, the most common barriers for simultaneous resections were patient comorbidities and extrahepatic disease, whereas general surgeons additionally identified transferring care to another facility. Lack of information regarding non-responders is relevant given our relatively low response rate. Our respondents mostly worked in academic settings, which may not be representative of the majority of surgeons who manage colorectal cancer. Conclusions: Surgeon support for simultaneous resection increased with less complex surgery and was similar among hepatobiliary and general surgeons. Surgeons’ perceived practice patterns and barriers to simultaneous resection should inform clinical trials and disease care pathways.
