OBJECTIVE: To determine the associations between the presence and depth of uterine corpus invasion and survival in patients with cervical cancer.
METHODS: Clinical data of patients with stage IA2-IIB cervical cancer who underwent radical hysterectomy between 2004 and 2016 were retrospectively reviewed. Uterine corpus invasion was identified from a review of uterine pathology. Independent prognostic factors for 5-year disease-free survival (DFS) and overall survival (OS) were identified using multivariate forward stepwise Cox proportional hazards regression models.
RESULTS: A total of 1414 patients with stage IA2-IIB cervical cancer from 11 medical institutions in China were included. Retrospective review of the original pathology reports revealed a missed diagnosis of uterine corpus invasion in 38 (13.4%) patients and a misdiagnosis in 20 (1.8%) patients. Therefore, 284 patients with cervical cancer and uterine corpus invasion (90 [31.7%] patients had endometrial invasion, 105 [37.0%] patients had myometrial invasion <50%, and 89 [31.3%] patients had myometrial invasion ≥50%), and 1130 patients with cervical cancer without uterine corpus invasion were included in the analysis. The 5-year DFS and OS were significantly shorter for patients with uterine corpus invasion compared to patients with no uterine corpus invasion. Myometrial invasion ≥50% was an independent prognostic factor associated with decreased 5-year DFS (aHR, 2.307, 95% CI, 1.588-3.351) and 5-year OS (aHR, 2.736, 95% CI, 1.813-4.130), while myometrial invasion <50% or endometrial invasion had no effect on patient outcomes.
CONCLUSIONS: Diagnosis of uterine corpus invasion is frequently missed. Myometrial invasion ≥50% within the uterine corpus was an independent factor associated with worse prognosis in patients with cervical cancer, while myometrial invasion <50% or endometrial invasion had no effect on outcomes.
