Abstract

Background: The benefit of neoadjuvant chemotherapy (NAC) in patients with resectable colorectal liver metastasis (CRLM) is debatable. This study aimed to establish a definition of biologically borderline resectable CRLM based on early surgical failure.

Methods: One hundred forty-two patients who underwent upfront surgery for resectable CRLM were examined. Potential predictors of early surgical failure were investigated to establish a definition of biologically borderline resectable CRLM. The impact of NAC on overall survival (OS) in patients with borderline resectable CRLM was examined, as were predictors of OS.

Results: Extrahepatic lesions (p < 0.01) and tumor ≥ 30 mm with carcinoembryonic antigen (CEA) concentration ≥ 20 ng/mL (p = 0.02) were independent predictors of early surgical failure. Borderline resectable CRLM was defined as extrahepatic lesions or tumor size ≥ 30 mm with CEA concentration ≥ 20 ng/mL. Fifty-eight patients had borderline resectable CRLM. Three-year OS was significantly higher in borderline resectable CRLM patients who received NAC than in those who did not (71.8% vs. 52.7%) and 5-year survival was also significantly higher in this group (62.8% vs. 25.5%).

Conclusion: We have proposed a simple definition of biologically borderline resectable CRLM based on early surgical failure. NAC could be a good indication for patients who met the definition.

期刊介绍： The International Journal of Clinical Oncology (IJCO) welcomes original research papers on all aspects of clinical oncology that report the results of novel and timely investigations. Reports on clinical trials are encouraged. Experimental studies will also be accepted if they have obvious relevance to clinical oncology. Membership in the Japan Society of Clinical Oncology is not a prerequisite for submission to the journal. Papers are received on the understanding that: their contents have not been published in whole or in part elsewhere; that they are subject to peer review by at least two referees and the Editors, and to editorial revision of the language and contents; and that the Editors are responsible for their acceptance, rejection, and order of publication.
