Robotic hepatic cyst marsupialization is equivalent to laparoscopy

Abstract

invasive disease respectively. Surgery was also shown to meaningfully affect survival (p=0.004), with those that underwent surgery having a median survival of 8 months compared to 2 months for those that did not undergo surgery. Sub-analysis of those that underwent surgery demonstrated that lymphadenectomy was significant (p<0.001), with a median survival of 8 months in those with lymph nodes removed and 1.1 months in those without lymph nodes removed. However, nodal positivity did not have an imperative effect on survival (p=0.7) in those that underwent lymphadenectomy. The univariate analysis resulted in a hazard ratio (HR) of 9.14 for those with distant metastasis versus localized disease (HR=1.00, p=0.01), and a hazard ratio of 0.33 for patients undergoing cancer-directed surgery versus no surgery (HR=1.00, p=0.01). With multivariate analysis, only metastatic disease (HR=5.93, p=0.04) remained a significant predictor of survival. Conclusion: Pancreatic carcinosarcoma carries a poor prognosis, with median survival under one year from the time of diagnosis. Metastatic disease was a significant predictor of early mortality as identified by both univariate and multivariate analysis. Evidence also indicates that surgery may have a beneficial effect on survival, suggesting that those who are good candidates for surgery should undergo resection.
