Abstract

Background: Identifying pancreatic cancer patients at high risk of early mortality following pancreaticoduodenectomy (PD) is important for treatment decisions in a multidisciplinary setting. This study examines the preoperative predictors of early mortality following PD and combines these variables into an early mortality risk score (EMRS). Methods: Medical records of patients who underwent PD for pancreatic adenocarcinoma at the Johns Hopkins Hospital between 30 August 1993 and 28 February 2005 were reviewed. Cox proportional hazards analysis was performed to identify predictors of early mortality, defined as death at 9 and 12 months. EMRS was constructed from univariate associated risk factors (age >75 years, tumor size ≥3cm, poor differentiation, co-morbid diseases) with each factor assigned 1 point (range of 0-4). EMRS was evaluated as an independent predictor of death at 9 and 12 months. Results: On univariate analysis, risk factors for death at 9 months included age ≥75 years (RR, 1. 6; p =.009), comorbid disease (RR, 1. 5; p = 0. 020), tumor ≥3 cm (RR, 1. 4; P = 0. 050), and poor differentiation (RR, 2. 1; P lt;0. 001). EMRS was associated with early mortality among those who did (p = 0. 038) and did not receive adjuvant treatment (p lt;0. 001). A modified EMRS without tumor differentiation was also associated with early mortality (p lt; 0. 001). Results persisted when reanalyzed using death at 12 months. Conclusions: EMRS may identify patients at risk of early mortality following PD who may be candidates for alternatively sequenced treatment protocols. Prospective validation of this EMRS is needed.
