Influence of uterine corpus invasion on prognosis in stage IA2–IIB cervical cancer: A multicenter retrospective cohort study

•Retrospective review of uterine corpus invasion revealed a rate of 13.4% for missed diagnosis and 1.8% for misdiagnosis.•The depth of myometrial invasion within the uterine corpus significantly affected survival in patients with cervical cancer.•Myometrial invasion ≥50% within the uterine corpus was an independent prognostic factor associated with decreased survival.•Myometrial invasion <50% or endometrial invasion within the uterine corpus had no effect on patient outcomes.
