Clinicopathologic Characteristics and Prognostic Factors of Stage I and II Endometrial cancer of the uterus: A Study of 59 Cases / 대한산부인과학회지

ABSTRACT

OBJECTIVE: The purpose of this study was to evaluate the clinicopathologic findings, treatment, and prognostic factors of uterine endometrial cancer. METHODS: We retrospectively reviewed 59 patients with histologically proven stage I and II endometrial cancer between January 1994 and December 2004, for clinical profiles and survival. The survival of patients was determined by description of last follow up date in medical records or phone calls. RESULTS: The median age at the time of diagnosis was 51 years (range 30-71 years) and the most common presenting symptom was vaginal bleeding (83.0%). Endometrioid adenocarcinoma was the most common (96.6%) histologic type of all cases. Forty-nine patients (83.0%) were FIGO stage I and 10 patients were stage II (17.0%), and the histological grades of the tumors were 23 (39.0%) grade 1, 17 (28.8%) grade 2, 7 (11.9%) grade 3, and 12 (20.3%) unknown, respectively. All patients were treated by surgery as primary treatment and given postoperative adjuvant therapy including radiation therapy (32.2%), concurrent chemotherapy and radiation therapy (6.8%), and chemotherapy (3.4%). The 5-year disease free survival rate (DFSR) of stage I and stage II were 92.7% and 66.7%, respectively. The age (> or =60) and menopausal status were significant prognostic factors by univariate anlaysis (p=0.0077; p=0.0149, respectively). However, parity, FIGO surgical stage, histological grade, myometrial invasion, and lymph-vascular space invasion were not significant prognostic factors (p>0.05). CONCLUSION: The age (> or =60) and menopause state were significant prognostic factors of stage I and II uterine endometrial cancer affecting survival of the patients.
