The objective of this study was to evaluate clinical significance of endometrial and corporal extensions of Carcinoma of the uterine cervix.

The 273 patients with locally advanced cervical cancer who underwent radical hysterectomy after neoadjuvant chemotherapy between Jan 1983 to May 1998 were included in this study and endometrial and corporal extension was examined by pathologic report. Then, clinical characteristics such as age, stage, tumor size, geographic contour, the lymph node and parametrial invasions, recurrence rate, and 5 year-survival rate were compared between extension(n=30) and non-extension(n=243) group. Pearson chi-square test, Fisher's exact test, and Kaplan-mayer survival analysis were used for calculation of statistical significance between two group. p-value less than 0.05 was considered to be clinically significant.

The incidence of endometrial and corporal extension in this locally advanced cervical cancer group was 11% (30/273). The endometrial and corporal extension were closely related with advanced stage, larger cervical tumor mass, endophytic type, and pelvic lymph node metastasis. However, 5-year disease free survival rates or 5-year actuarial survival rates did not show statistically significant differences between extension and non-extension group. (7S% vs 83% and 81% vs 84%, respectively)

The endometrial and corporal extension were closely associated to high risk factors of advanced cervical cancer. Though its clinical significance for poor outcome were not proved in this study, prospective study with more patients is needed to clarify its clinical significance.
