Abstract

Background: Liver resection is a key therapeutic strategy to improve survival in patients with colorectal cancer liver metastases. Underutilization may negatively affect outcomes. Using a Web-based survey and standardized imaging scenarios, this study assessed medical oncologists’ (MOs) perceptions of resectability, preferences for chemotherapy sequencing, and referral for surgical consultation in a static patient profile of good performance status and no extrahepatic spread but varying bulk and distribution of disease. Methods: A total of 190 US-based MOs were surveyed. A single patient profile was created and combined with 10 different sets of liver computed tomographic images displaying a broad spectrum of metastases. Assessments of resectability and ranking were compared with the results obtained from an expert panel of 3 hepatic surgeons. Results: The expert hepatic surgeons designated 8 scans resectable, 1 borderline resectable/convertible, and 1 unresectable. In the 8 resectable cases, 34.4 % of MOS perceived the case to be initially resectable, 41.7 % potentially resectable after chemotherapy response, and 23.9 % unresectable. Increasing number of lesions, larger tumor diameter, and bilateral disease were associated with lower resectability perception (P
