An Analysis of Clinicopathologic Prognostic Factors Affecting Survival in Patients with Uterine Endometrial Cancer / 대한산부인과학회잡지

ABSTRACT

OBJECTIVE: This study was performed to evaluate the clinicopathologic characteristics and prognostic factors of uterine endometrial cancer affecting survival of the patients. METHODS: Form Jan. 1995 to Dec. 2001, medical records including operation record and pathologic reports of 111 patients with histologically proven endometrial cancer at Samsung Medical Center were reviewed. The survival of patients was determined by description of last follow up date in medical records or phone calls. RESULTS: The median age of all patients was 52 years and the most common presenting symptom was abnormal vaginal bleeding (74.0%). Histologic type of endometrioid adenocarcinoma was the most common (90%) type of all endometrial cancers. The grades were classified into G1 (65.7%), G2 (17.1%), G3 (12.6%) and unknown (4.5%). The FIGO surgical stage was also classified into stage I(75.7%), stage II (14.4%), stage III (9.0%), and stage IV (0.9%). All patients were treated by primary surgery and postoperative adjuvant therapy including radiation therapy (54.1%), chemotherapy (4.5%) was applied. The overall 5-year disease free survival rate (DFSR) was 86.5% and overall 5-year survival rate was 87.8%. The age (p=0.04), grade (p=0.04), myometrial invasion (p=0.047), FIGO surgical stage (p=0.0067), lymph node metastasis (p=0.0001), lymphovascular space invasion (p=0.01) and C-erb B2 (p=0.04) were significant prognostic factors by univariate analysis. CONCLUSION: The age, grade, myometrial invasion, FIGO surgical stage, lymph node metastasis, lymphovascular space invasion and C-erb B2 were significant prognostic factors of uterine endometrial cancer affecting survival of the patients.
