FIGO stage IV (HR3.405, 95 %CI 2.132–5.625), open surgery (HR2.692, 95 %CI 1.178–3.454), durations of drainage ≥ 7 d (HR2.414,95 %CI 1.125–2.392), postoperative serum albumin < 30 g/L (HR1.912,95 %CI 1.263–2.903), postoperative blood sugar ≥ 10 mmol/L (HR1.774,95 %CI 1.102–2.534) were the independent risk factors of SSI in patients with endometrial carcinoma (all p <  0.05). Here, ALB is linked to endometrial carcinoma.
