Non-primary cervical adenocarcinomas.
We reviewed 16 non-primary cervical adenocarcinomas collected during a six year period. Ten tumors originated in the endometrium, three in the ovary and one each in the bladder, colon and fallopian tube. Tumor spread was identified by combined lymphovascular involvement and stromal invasion in five of the 16 cervices, lymphovascular involvement alone in four cervices, stromal invasion alone in two cervices, lymphovascular involvement with stromal invasion and cervical implantation in two cervices and cervical implantation alone in three cervices. The three tumors with surface implantation alone were of endometrial origin, had minimal if any myometrial invasion, no extrauterine metastases and two had malignant peritoneal washings. Of the 13 tumors with cervical lymphovascular involvement and/or stromal metastases, 11 had ovarian, nodal and/or peritoneal metastases. We conclude that cervical implantation occurs exclusively with endometrial adenocarcinomas, that it follows previous cervical instrumentation and that the prognosis is dependent on the histoprognostic features of the primary endometrial tumor. In contrast, cervical lymphovascular involvement and/or stromal metastases usually reflects disseminated pelvic or abdominal malignancy with a poor prognosis. However histological examination may not afford separation of these two lesions if local cervical invasion is advanced, if spread has occurred by more than one mode or if insufficient clinical/surgical information is provided.
