Albumin-to-alkaline phosphatase ratio as a novel prognostic indicator for patients undergoing minimally invasive lung cancer surgery: A prospective propensity score matching study.

•Propensity-score matching analysis to study prognostic roles of basic albumin-to-alkaline phosphatase ratio in operable NSCLC.•Lower albumin-to-alkaline phosphatase ratio is significantly associated with worse prognosis of operable NSCLC.•Albumin-to-alkaline phosphatase ratio serves as an excellent prognostic indicator in minimally invasive lung cancer surgery.
