Study scheme. Of 3248, 1412 and 922 consecutive patients with colorectal cancer who were treated surgically at Juntendo University Hospital between 2002 and 2018, at Juntendo University Nerima Hospital between 2007 and 2019, and at Juntendo University Shizuoka Hospital between 2011 and 2018, respectively, 274 (8.4%), 89 (6.3%) and 57 (6.2%) presented with synchronous CRLM. Among these respective patients, 105, 6 and 14 underwent simultaneous resection for colorectal cancer and synchronous CRLM with curative intent. Finally, 78, 4 and 12 patients, who received POAC after simultaneous resection with curative intent for colorectal cancer and synchronous CRLM, were enrolled retrospectively in the study. The patients were divided into a L-OHP (+) group (POAC with an oxaliplatin-based regimen, n = 47) and a L-OHP (−) group (POAC with a fluoropyrimidine regimen, n = 47). A total of 21 patients in each group were matched in one-on-one pair PS matching analysis
