P3.16-45 The Rates and Survival of Surgically-Resected Second Primary Lung Cancers in Patients Undergoing Resection of an Initial Primary Lung Cancer.

Abstract

Males/60 Females). Mean age was 66 + 9 years old (range:30-85). The majority of patients had adenocarcinoma (n¼101;72%), followed by epidermoid (n¼29;21%) and carcinoid tumors (n¼10;7%). Lobectomy was the most common operation (n¼119;85%), followed by anatomic segmentectomies (n¼21;15%). Mean overall operative time was 209 + 80 minutes (214 + 80 for lobectomies and 167 + 51 for segmentectomies; p¼0.01). Mean number of lymph nodes resected was 12 + 6, and the mean number of lymph nodes stations sampled was 6 + 1. There was no conversion to either VATS or thoracotomy in our series; neither major intraoperative bleeding. Postoperative complications occurred in 30 patients (21%). Prolonged air leak was the most common (n¼13;9%) and 7 patients were discharged with a chest tube. Chylothorax occurred in 4 patients (2.8%), but all were treated with dietetic measures. Median length-of-stay was 3 days (IQR:2-6). The overall 30-day mortality was 0.5% (n¼1). One patient had a procedurerelated death, 25 days after a lobectomy. He developed pneumonia, sepsis and multiple organ failure. 138 patients (98.5%) are still under follow-up. Disease recurrence occurred in 7.8% of patients (n¼11). Conclusion: Robot-assisted pulmonary resection is safe, effective and provides good outcomes, even within the context of an initial experience. Further follow-up should provide insight regarding long-term oncologic disease control.
