There are scant data regarding oncologic outcomes of laparoscopic liver resection (LLR). The aim of this study is to analyze the oncologic outcomes of LLR for malignant liver tumors (MLT).Methods:
This was a prospective IRB-approved study of 123 patients with MLT undergoing LLR. Kaplan–Meier disease-free (DFS) and overall survival (OS) was calculated.Results:
Tumor type was colorectal in 61%, hepatocellular cancer in 21%, neuroendocrine in 5% and others in 13%. Mean tumor size was 3.2 ± 1.9 cm and number of tumors 1.6 ± 1.2. A wedge resection or segmentectomy was performed in 63.4%, bisegmentectomy in 24.4%, and hemihepatectomy in 12.2%. Procedures were totally laparoscopic in 67% and hand-assisted in 33%. Operative time was 235.2 ± 94.3 min, and conversion rate 7.3%. An R0 resection was achieved in 90% of patients and 94% of tumors. Median hospital stay was 3 days. Morbidity was 22% and mortality 0.8%. For patients with colorectal liver metastasis, DFS and OS at 2 years was 47% and 88%, respectively.Conclusions:
This study shows that LLR is a safe and efficacious treatment for selected patients with MLT. Complete resection and margin recurrence rate are comparable to open series in the literature. J. Surg. Oncol. 2016;113:127–129. © 2015 Wiley Periodicals, Inc.
