Influence of Obesity on the Course of Malignant Neoplastic Disease in Patients After Pulmonary Metastasectomy.

In Vivo 2018 January
BACKGROUND/AIM: The aim of the study was to determine whether increased body mass index (BMI) in patients operated on for lung metastases influences the course of the disease.

MATERIALS AND METHODS: The retrospective data of 97 patients previously operated on for different malignancies were analyzed. There were 40 obese patients (BMI >30 kg/m2 , mean 33.9±4.5) and 57 non-obese patients (BMI 25.8±2.7 kg/m2 , p<0.001). Disease-free interval (DFI), the overall survival (OS) and survival after pulmonary metastasectomy were analyzed.

RESULTS: DFI and OS were longer in obese than in non-obese patients (82.1±83.5 months vs. 43.0±44.4, p<0.01 and 110.7±81.3 months vs. 69.9±52.9 p<0.005, respectively). Survival after pulmonary metastasectomy was 27.2±25.6 months and was longer in obese and overweight patients than in normal weight patients (20.2±18.4 months vs. 29.4±26.5, p<0.05).

CONCLUSION: Being obese or overweight is a favorable prognostic factor in patients after surgical resection of lung metastases of different malignancies.
