PURPOSE: There have been limited studies to correlate the 30 d post -op mortality and hospital duration of lung cancer resection in overweight and obese patients.
METHODS: We performed a retrospective study of patients who underwent surgical resection for Lung cancer from 2006 to 2010. Data on patient demographics, weight, height, pathology findings and hospital course were abstracted after appropriate IRB approval. Mortality was defined as any cause of death within 30 d of surgery. Hospital duration was defined as the days from date of operation till discharge.
RESULTS: 320 lung resections were performed for lung cancer. Median age were 67(25-88) and 185(57.8%) were females. The body mass index (BMI) distribution were 121(37.8%) in BMI<25 and 199(62.18%) in BMI≥25.The distribution in different BMI groups(as per WHO classification) were 75 in BMI ≥30, 124 in BMI 25-29.9 group, 106 in 18.5-24.9 and 15 were <18.5. In patients with BMI < 25, surgical procedures consisted 76(62.81%) Lobectomy, 38(31.40%) wedge resection and 7(5.79%) pneumonectomy. In patients with BMI ≥ 25, surgical procedures consisted: 131(65.83%) underwent Lobectomy, 61(30.65%) wedge resection and 7(3.52%) pneumonectomy. Tumor histology were: adenocarcinoma 138(42.9%), squamous cell cancer 107(33.3%), bronchoalveolar 25(7.7%), large cell 19(5.9%) and mixed 31(9.68%). The 30 day mortality rate was 1.7 % (6 patients), 5 of whom underwent open lobectomy and 1 underwent wedge and only 2 had BMI ≥ 25. The causes of death in all 6 patients were different and included Pulmonary embolism, Ischemic bowel, Renal Failure, Cerebrovascular accident, GI bleed and Suicide. Median hospital stay was 5d in lower BMI group and 4d in BMI≥25 (p=0.52).
CONCLUSIONS: Our study showed that there is no significant difference in 30d post-op mortality and hospital duration in overweight and obese versus normal weight patients undergoing lung cancer surgery.
CLINICAL IMPLICATIONS: There is increasing prevalence of obesity and lung cancer in United States and hence this kind of study will give some evidence regrading the risk of surgery in these patient group.
