Twelve cases of ovarian
metastases
from cervical carcinomas, most with clinical manifestations of ovarian involvement, are reported. The patients were 23-73 years of age (average, 43 years). The ovarian and cervical tumors were synchronous in eight patients; in three, ovarian tumors were discovered 10 months, 2.5, and 3 years after the detection of a
cervical neoplasm
. In one patient, the cervical tumor was not discovered until autopsy 7 months after presentation. Four patients had abdominal swelling or distention, three had vaginal bleeding, three had an abnormal Papanicolaou smear, and two had masses discovered during pelvic examination. The ovarian tumors, six of which were bilateral, ranged from 5-17 cm (average, 9.5 cm) in maximal dimension in 11 patients; in the 12th patient, the involved ovary was not enlarged. The cervical tumors were grossly evident in 10 patients. They were usually deeply invasive, often with extracervical extension. Four were squamous cell carcinomas; two, small cell carcinomas; one, a mixed small cell carcinoma and adenocarcinoma; one, a mixed poorly differentiated carcinoid and adenocarcinoma; two, adenosquamous carcinomas; one, a transitional cell carcinoma; and one, an undifferentiated carcinoma. Various features, including bilaterality of the ovarian tumors, the finding that the histologic features of the ovarian tumors typically were unusual for a primary ovarian neoplasm, and the presence of extensive extracervical disease, led to the conclusion that the ovarian tumors were metastatic from the cervix. Although ovarian
metastases
of cervical carcinoma are uncommon, this series illustrates that, occasionally striking examples with clinical manifestations of ovarian involvement occur.

Neuroendocrine carcinomas of the uterine cervix are rare tumors with early
metastases
, highly aggressive clinical behavior, and poor clinical outcome. Several adhesion molecules like cadherins have been tested in an attempt to explain their unique characteristics. Cluster differentiation 44 (CD44) is a widely expressed cell surface glycoprotein that serves as an adhesion molecule in cell-to-substrate and cell-to-cell interaction. We have examined the expression of the standard CD44 (CD44s) by immunohistochemical stains in the paraffin-embedded
cervical neoplasm
tissue of 17 cases of primary cervical neuroendocrine carcinoma, 28 cases of cervical adenocarcinoma, and 50 cases of cervical squamous cell carcinoma. Loss of CD44s expression was found in 16 of 17 neuroendocrine carcinomas, 14 of 28 adenocarcinomas, and three of 50 squamous cell carcinomas. The differences were statistically significant. We also examined immunohistochemically the expression of the BRG-1 subunit of the SWI-SNF complex, which has been reported to regulate the expression of CD44 in all cases. Loss of BRG-1 expression was observed in 12/16, 6/14, and 1/3 CD44s-negative neuroendocrine carcinomas, adenocarcinomas, and squamous cell carcinomas, respectively. This study suggests that loss of the CD44s molecule may imply special biological behaviors of cervical neuroendocrine carcinomas, and loss of expression of BRG-1 may contribute to this.

Metastatic tumors within the cervix are uncommon if one excludes endometrial carcinoma, which involves the cervix by direct spread. A variety of other neoplasms rarely
metastasize
to the cervix and, in most cases, the diagnosis is straightforward because of a combination of clinical and pathologic parameters, common features of metastatic carcinoma within the cervix including predominant involvement of the deep stroma, absence of surface involvement and of an in situ component, and prominent lymphovascular permeation. We describe 6 cases of metastatic adenocarcinoma involving the cervix with superficial "mucosal" involvement mimicking primary cervical adenocarcinoma or adenocarcinoma in situ. In 5 cases, the primary adenocarcinoma was in the ovary or peritoneum and was of serous (4 cases) or clear-cell (1 case) type. In the other case, the primary neoplasm was in the pancreas and this was initially interpreted as a primary cervical adenocarcinoma. In the cases of primary ovarian or peritoneal carcinoma, the mucosal tumor within the cervix, which was discovered at the same time as the ovarian or peritoneal neoplasm, raised the possibility of synchronous independent lesions or metastasis from the cervix to the ovary or peritoneum. Positive staining for WT1, p53, and estrogen receptor in the cases of serous carcinoma and an absence of human papillomavirus by linear array genotyping in all cases was of value in excluding a primary
cervical neoplasm
, although these ancillary studies are supplementary to microscopic examination. In those cases with an ovarian or peritoneal primary, the likely pathogenesis of the cervical involvement is transtubal and intrauterine spread. It is important for the pathologist to be aware of the possibility of cervical mucosal metastasis to avoid an erroneous diagnosis of a primary cervical adenocarcinoma or adenocarcinoma in situ.

Neuroendocrine carcinomas of the cervix account for less than 2% of all invasive cervical cancers and are classified as low-grade (carcinoid, atypical carcinoid tumor) or high-grade (known as small- and large-cell) neuroendocrine carcinomas. There are increasing data showing that cervical neuroendocrine carcinomas may be associated with the human papillomavirus (HPV), especially HPV18, and most will stain positive for p16. Immunohistochemistry markers such as synaptophysin and CD56 are the most sensitive markers. Although there are no commonly associated mutations,
PIK3CA
,
KRAS
, and
TP53
are the most frequently found mutations in neuroendocrine tumors. Neuroendocrine cervical carcinomas are exceedingly aggressive tumors with a high tendency for nodal involvement and distant
metastases
. Age, lymph node
metastases
, smoking, pure small-cell histology, and tumor size are independent prognostic factors. Overall, the 5-year survival rate is 36% and the median overall survival ranges between 22 and 25 months. Treatment options are often extrapolated from small-cell lung cancer and limited retrospective studies. The preferred treatment is a multimodal approach of surgery, chemoradiation, and systemic chemotherapy. The most common chemotherapy regimen used as initial therapy is a combination of cisplatin and etoposide. In the setting of recurrent disease, a combination of topotecan, paclitaxel, and bevacizumab has demonstrated favorable outcomes. Multicenter tumor registries, such as the Neuroendocrine
Cervical Tumor
Registry (NeCTuR), are an opportunity to evaluate patterns of disease treatment and oncologic outcomes.
