In all, 494 patients were included, of them 429 (86.8%) were male and
65 (13.2%) were female. The median follow-up was 24 months (12-132
months). At the time of surgery, the number of patients in groups 1, 2
and 3 were 202 (40.9%), 215 (43.5%) and 77 (15.6%), respectively. The
mean operation time and time to postoperative oral feeding were longer
and major complications were statistically higher in Group 3 compared to
Groups 1 and 2 (p=0.019, p<0.001 and p=0.025 respectively).
Although the mean overall survival (OS), cancer-specific survival (CSS),
recurrence-free survival (RFS) and metastasis-free survival (MFS) was
shorter in cases with BMI ≥30 kg/m2 compared with
other BMI groups, differences were not statistically significant
(p=0.532, p=0.309, p=0.751 and p=0.213 respectively).
