Clinical outcome of pancreatic cancer patients with indeterminate pulmonary nodules.

Abstract

220Background: Indeterminate pulmonary nodules (IPNs) are often found on staging CT scans for pancreatic cancer and pose a treatment conundrum since resection is contraindicated in metastatic setting. Here we aim to determine the clinical outcome of pancreatic cancer patients with IPNs undergoing curative resection. Methods: Retrospective analysis of 1,182 pancreatic cancer patients in the institutional Oncology Registry between 2007 and 2017 was conducted. Survival probabilities were estimated using the Kaplan-Meier method. Time was calculated from diagnosis to death for overall survival (OS), and from operation to recurrence for recurrence-free survival (RFS). Cox regression models were used to assess the effects of demographic, clinicopathologic, and treatment variables on OS and RFS. Results: IPNs were found in 50 patients undergoing surgery (43 pancreatoduodenectomy, 7 distal pancreatectomy). Negative margins were obtained in 82% of patients. Six and 44 patients had stage 0/I and stage II disease, re...
