Introduction:
While the resection of colorectal liver metastases is a well-established procedure, with survival rates superior to chemotherapy alone, controversial data still exist on liver resection for non-colorectal liver metastases (NCRLM). These patients comprise a diverse and heterogeneous group usually excluded from surgery. To date, only few retrospective reports are available on the surgical treatment of NCRLM. The NONCOLMET study aimed to build a comprehensive registry of patients undergoing liver resection for NCRLM, providing robust retrospective and prospective data to describe clinical practices, outcomes, and identify prognostic factors.
Methods:
The study consists of two phases: (1) retrospective collection of data from patients treated between 2010 and 2024 and (2) prospective enrolment from 2025. Patients aged ≥18 years with histologically confirmed NCRLM undergoing liver resection will be included. Data will be recorded via a standardized electronic case report form on the RedCap platform. The following endpoints will be evaluated: oncological outcomes including overall survival, disease-free survival, and disease relapse; post-operative mortality at 30 and 90 days with causes of death; post-procedural complications; predictor variables of short- and long-term outcomes. These outcomes will be used to elaborate a risk score model.
Conclusions:
NONCOLMET will offer crucial insights into the surgical management of NCRLM, helping refine patient selection criteria and informing future clinical guidelines.
