BACKGROUND: Outcomes and survival of truly unresectable locally advanced pancreatic cancers (LAPC) is often reported along with borderline resectable pancreatic cancers especially from a real world cohort. METHODS: The audit of LAPC patients, diagnosed based on the NCCN criteria between February 2013 and January 2016 was used to identify patients starting and continuing treatment in our institution. Practice patterns, outcomes and prognostic factors for overall survival were evaluated. RESULTS: Of the 83 patients, 52 were available for inclusion in the analysis. Median age was 56 years (range 30-77), with males constituting 75% of patients. Baseline comorbidities seen were diabetes mellitus, hypertension and cardiac dysfunction in 46.1%, 69.1% and 52% of patients respectively. 84.6% of patients had arterial vascular involvement as criteria for unresectable LAPC. 50% of patients received chemotherapy only, while the remainder received chemotherapy and concurrent chemoradiation. One patient was able to undergo curative R0 resection. FOLFIRINOX was the most commonly used chemotherapy regimen (53.8%). With a median follow up of 15.9 months, median progression free survival (mPFS) was 7.26 months (95% CI: 5.75-8.76) and median OS was 11.8 months (95% CI: 9.96-13.61). None of the potential prognostic factors evaluated, i.e., age, gender, nodal status, pre-treatment CA 19.9 levels, showed correlation with OS. CONCLUSION: This analysis shows outcomes in unresectable LAPC comparable to existing literature. Surgery in unresectable LAPC patients is less common than seen in previously published studies, more likely due to this cohort being truly 'unresectable' in terms of major arterial involvement.
