In patients with endometrial carcinoma the prognostic significance of clinical and histopathologic variants of cervical involvement is unknown. Fifty-eight patients with endometrial carcinoma and cervical involvement diagnosed by gross examination or endocervical curettage are reviewed. Three clinicopathologic groups were identified: gross cervical involvement (10 patients), occult stromal invasion (25), and no evidence of stromal invasion (23). There were no differences in clinical, pathologic, surgical, or therapeutic characteristics. There was no significant difference in actuarial 5-year survival rates between patients with gross cervical involvement (70%) and occult disease (65%). There was also no significant difference in survival rates among patients with occult cervical stromal invasion (67%). The presence of cervical involvement in endometrial carcinoma is an important prognostic factor. However, the extent of cervical involvement does not appear to be of significant prognostic value.
