BackgroundOptimized anaesthetic management might improve the outcome after cancer surgery. A retrospective analysis was performed to assess the association between spinal anaesthesia (SpA) or general anaesthesia (GA) and survival in patients undergoing surgery for malignant melanoma (MM).MethodsRecords for 275 patients who required SpA or GA for inguinal lymph-node dissection after primary MM in the lower extremity between 1998 and 2005 were reviewed. The follow-up ended in 2009. Survival was calculated as days from surgery to the date of death or last patient contact. The primary endpoint was mortality during a 10 yr observation period.ResultsOf 273 patients included, 52 received SpA and 221 GA, either as balanced anaesthesia (sevoflurane/sufentanil, n=118) or as total i.v. anaesthesia (propofol/remifentanil, n=103). The mean follow-up period was 52.2 (sd 35.69) months after operation. Significant effects on cumulative survival were observed for gender, ASA status, tumour size, and type of surgery (P=0.000). After matched-pairs adjustment, no differences in these variables were found between patients with SpA and GA. A trend towards a better cumulative survival rate for patients with SpA was demonstrated [mean survival (months), SpA: 95.9, 95% confidence interval (CI), 81.2-110.5; GA: 70.4, 95% CI, 53.6-87.1; P=0.087]. Further analysis comparing SpA with the subgroup of balanced volatile GA confirmed this trend [mean survival (months), SpA: 95.9, 95% CI, 81.2-110.5; volatile balanced anaesthesia: 68.5, 95% CI, 49.6-87.5, P=0.081].ConclusionsThese data suggest an association between anaesthetic technique and cancer outcome in MM patients after lymph-node dissection. Prospective controlled trials on this topic are warranted.
