Background Recurrence after curative hepatectomy for colorectal liver metastases (CRLM) is common. We sought to determine if number and sites of resections of recurrence after hepatectomy for CRLM impact survival. Methods The study included patients who underwent resection of recurrence following complete curative-intent resection of CRLM during 1998-2016 at two academic medical centers in Houston, USA, and Rome, Italy. The survival impacts of number and sites of resections of recurrence were evaluated. Patients with synchronous extrahepatic disease at curative CRLM resection were excluded. Results Among 2163 patients who underwent curative hepatectomy, 1456 (67.3%) developed a recurrence. Four hundred seventy-eight patients underwent one (322/478; 67.4%) or two or more (156/478; 32.6%) resections of recurrence. The 5-year overall survival (OS) rate was higher in patients with resected than unresected recurrence (70.2% vs. 24.0%; p < 0.001). In patients who underwent only one resection of recurrence, the 5-year OS rate differed by location (lung, 81.6%; liver, 64.3%; other, 54.1%). In patients who underwent two or more resections of recurrence, the 5-year OS rate was similar for liver-only resection (87.5%) and resection of liver and other sites (66.1%) (p = 0.223) and for liver-only resection and other-sites-only resection (80.7%) (p = 0.258); 5-year OS rate by site of first resection of recurrence did not differ between liver (78.5%) and lung (81.8%) (p = 0.502) but was worse for other sites (61.1%) than for lung (p = 0.045). Conclusion When recurrence after initial CRLM resection is resectable, the ability to undergo resection was associated with improved survival and can be considered as an option regardless of the number of recurrence and resection. Sites of resection of recurrence impact survival and should be considered.

Abstract

Background Recurrence after curative hepatectomy for colorectal liver metastases (CRLM) is common. We sought to determine if number and sites of resections of recurrence after hepatectomy for CRLM impact survival. Methods The study included patients who underwent resection of recurrence following complete curative-intent resection of CRLM during 1998-2016 at two academic medical centers in Houston, USA, and Rome, Italy. The survival impacts of number and sites of resections of recurrence were evaluated. Patients with synchronous extrahepatic disease at curative CRLM resection were excluded. Results Among 2163 patients who underwent curative hepatectomy, 1456 (67.3%) developed a recurrence. Four hundred seventy-eight patients underwent one (322/478; 67.4%) or two or more (156/478; 32.6%) resections of recurrence. The 5-year overall survival (OS) rate was higher in patients with resected than unresected recurrence (70.2% vs. 24.0%; p < 0.001). In patients who underwent only one resection of recurrence, the 5-year OS rate differed by location (lung, 81.6%; liver, 64.3%; other, 54.1%). In patients who underwent two or more resections of recurrence, the 5-year OS rate was similar for liver-only resection (87.5%) and resection of liver and other sites (66.1%) (p = 0.223) and for liver-only resection and other-sites-only resection (80.7%) (p = 0.258); 5-year OS rate by site of first resection of recurrence did not differ between liver (78.5%) and lung (81.8%) (p = 0.502) but was worse for other sites (61.1%) than for lung (p = 0.045). Conclusion When recurrence after initial CRLM resection is resectable, the ability to undergo resection was associated with improved survival and can be considered as an option regardless of the number of recurrence and resection. Sites of resection of recurrence impact survival and should be considered.
