The role of SILC is still controversial. Until now, no real significant benefit has been proven: overall satisfaction is the only clear advantage of SILC, and this is mainly related to cosmetic results. Indications to SILC are mainly limited to patients with uncomplicated disease, with BMI ≤ 30 kg/m(2), whose surgery is unlikely to be converted to an open or multiport approach.
Background/AimsThe prognosis of pancreatic adenocarcinoma (PAC) is poor. The serum carbohydrate antigen 19-9 (CA 19-9) level has been identified as a prognostic indicator of recurrence and reduced overall survival. The aim of this study was to identify preoperative prognostic factors and to create a prognostic model able to assess the early recurrence risk for patients with resectable PAC.MethodsA series of 177 patients with PAC treated surgically at the St. Andrea Hospital of Rome between January 2003 and December 2011 were reviewed retrospectively. Univariate and multivariate analyses were utilized to identify preoperative prognostic indicators.ResultsA preoperative CA 19-9 level >228 U/mL, tumor size >3.1 cm, and the presence of pathological preoperative lymph nodes statistically correlated with early recurrence. Together, these three factors predicted the possibility of an early recurrence with 90.4% accuracy. The combination of these three preoperative conditions was identified as an independent parameter for early recurrence based on multivariate analysis (p=0.0314; hazard ratio, 3.9811; 95% confidence interval, 1.1745 to 15.3245).ConclusionsPAC patient candidates for surgical resection should undergo an assessment of early recurrence risk to avoid unnecessary and ineffective resection and to identify patients for whom palliative or alternative treatment may be the treatment of choice.
LODDS are not correlated with the extension of the lymphadenectomy and are able to predict survival even if less than 15 nodes are examined. They permit an effective prognostic stratification of patients with a nodal ratio approaching 0 and 1. Further studies are needed to clarify their role and if they are capable of guaranteeing some advantages over pN and LNR.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
