Introduction: Surgical treatment of liver metastases is broadly accepted for colorectal and neuroendocrine tumors. However, the approach to liver metastases of other origins is not well established. The objective is the evaluation of factors that might be associated with better or worse perioperative outcomes (morbidity and mortality) and survival of patients with non-colorectal, non-neuroendocrine liver metastases (NCNNLM) treated surgically in a second level hospital. Material and Methods: A prospective study of patients with NCNNLM treated surgically or with radiofrequency was completed in San Cecilio University Hospital of Granada, between March 2003 and June 2013. The statistical analysis was made with IBM-SPSS version 21. Statistical significance was set at p ≤ 0.05. Survival data were analyzed by Kaplan-Meier's method. Results: Twenty-two patients with 26 surgeries were analyzed, 19 liver resections, 6 radiofrequency treatments and 1 combined case with surgery and radiofrequency. Operatory mortality was 0% and overage mortality was 23.1%. Univariate analysis only showed statistical significance in two of the factors, presence of positive lymphatic nodes during the surgery of the primary tumor and presence of extra-hepatic disease. Accumulated survival was 81%, 66% and 52% at 1, 2 and 3 years respectively. Conclusions: Despite the fact of treating together in the same group several different tumors, the surgical treatment of NCNNLM (with or without radiofrequency) has an acceptable survival rate. Thus, they can be treated with safety when we use a multi-disciplinary approach to these patients.
