Univariate and binary logistic regression analyses were performed to select the independent risk factors for PPCs during the patient’s postoperative hospitalization after surgery.Results: The incidence of PPCs was 24.8% (n=181/729). No patient died during the period of hospitalization. Logistic regression analysis revealed that body mass index (BMI) $24.0 kg/m2 (vs <24.0 kg/m2: OR 1.514, 95% CI 1.057–2.167, P=0.024), single segmentectomy (vs single lobectomy: OR 2.115, 95% CI 1.150–3.891, P=0.016), bilobectomy or combined lobectomy and segmentectomy (vs single lobectomy: OR 2.731, 95% CI 1.013–7.361, P=0.047), and right lung lobe surgery (vs left lung lobe surgery: OR 1.519, 95% CI 1.046–2.205, P=0.028) were independent risk factors for PPCs in lung cancer patients who received minimally invasive anatomic lung resections. Conclusion: Individual factors such as BMI ≥24.0 kg/m2, single segmentectomy, bilobectomy or combined lobectomy and segmentectomy, and right lung lobe surgery were independent risk factors of PPCs, which should be helpful for risk stratification, patient counseling, and perioperative care for lung cancer patients.
