Sumario:AIM OF THE STUDY: Recent advances in chemotherapy have increasingly enabled conversion surgery (CS) in patients with initially unresectable pancreatic cancer (PC), but patient selection remains controversial. We examined the characteristics of patients who would benefit from this procedure. MATERIAL AND METHODS: The clinical and pathological data of 38 patients with unresectable PC, who underwent CS after a favourable response to chemo(radio)therapy at our institute, were investigated. Univariate and multivariate analyses were performed to identify predictors for overall survival (OS). Several inflammation-based scores, such as the modified Glasgow prognostic score (mGPS), were also evaluated. RESULTS: The patients included 13 with locally advanced disease and 25 with metastatic disease. After non-surgical treatment with a median duration of six months, 27 patients (71%) underwent R0/1 resection, and the remainder underwent R2 resection. The two-year and five-year OS from the initial treatment for all patients were 64% and 29%, respectively, and the median survival was 29.1 months. Univariate analysis showed that age < 62 years, preoperative CA19-9 decrease rate ≥ 89%, preoperative mGPS-0, and R0/1 resection were related to a favourable OS. R0/1 resection and mGPS-0 were independent prognostic factors according to multivariate analysis. CONCLUSIONS: Preoperative mGPS is a potential predictor of survival and can aid selection of patients for whom CS could yield promising prognosis for initially unresectable PC.
