Optic neuropathy from metastatic squamous cell carcinoma of the cervix: An unusual CNS presentation

Leptomeningeal metastasis from cervical cancer: Report of two cases and a review of the literature

Leptomeningeal metastases from cervical cancer are extremely rare, with only 24 cases reported in the English-language literature. Leptomeningeal metastasis (LM) is usually a late event, but it can develop at any stage. A 44-year-old woman presented with vertigo, tinnitus, diminution of hearing, and a cervical tumor at the initial visit. She underwent whole brain radiotherapy and systemic chemotherapy. Five months after the initial visit, her condition deteriorated rapidly and she died. A 49-year-old woman underwent surgery and pelvic radiotherapy for cervical cancer. She underwent resection of lung metastases 2 years later and received systemic chemotherapy for lymph node metastases 4 years later. Five years after the initial visit, the patient suddenly presented with diplopia, headache, and vomiting; her clinical course was fulminant and she died. Most patients with LM present with diverse clinical manifestations and deteriorate rapidly despite multiple treatment modalities. Gynecologic oncologists should be aware of this rare complication.

Brain Metastases from Uterine Cervical and Endometrial Cancer

Simple Summary

This review investigated the prevalence, clinical characteristics, clinical presentation, diagnosis, treatment, and prognosis of patients with brain metastases from uterine cervical carcinoma (CC) and uterine endometrial carcinoma (EC). The findings of this review indicate the factors that can facilitate better treatment selection and, consequently, better outcomes in patients with CC and EC.

Abstract

Reports on brain metastases (BMs) from uterine cervical carcinoma (CC) and uterine endometrial carcinoma (EC) have recently increased due to the development of massive databases and improvements in diagnostic procedures. This review separately investigates the prevalence, clinical characteristics, clinical presentation, diagnosis, treatment, and prognosis of BMs from CC and uterine endometrial carcinoma EC. For patients with CC, early-stage disease and poorly differentiated carcinoma lead to BMs, and elderly age, poor performance status, and multiple BMs are listed as poor prognostic factors. Advanced-stage disease and high-grade carcinoma are high-risk factors for BMs from EC, and multiple metastases and extracranial metastases, or unimodal therapies, are possibly factors indicating poor prognosis. There is no “most effective” therapy that has gained consensus for the treatment of BMs. Treatment decisions are based on clinical status, number of the metastases, tumor size, and metastases at distant organs. Surgical resection followed by adjuvant radiotherapy appears to be the best treatment approach to date. Stereotactic ablative radiation therapy has been increasingly associated with good outcomes in preserving cognitive functions. Despite treatment, patients died within 1 year after the BM diagnosis. BMs from uterine cancer remain quite rare, and the current evidence is limited; thus, further studies are needed.

Ophthalmopathologic characterization of multicentric or metastatic neoplasms with an extraocular origin in dogs and cats

OBJECTIVE

To characterize the frequency and distribution of secondary ocular neoplasms in dogs and cats identified during necropsy.

METHODS

A retrospective analysis of necropsy records of dogs and cats was conducted, and cases with metastatic/multicentric neoplasms with an extraocular origin, involving the eyes, were selected.

RESULTS

From January 2015 to January 2019, we identified a total of 233 dogs and 100 cats with metastatic disease. Of these, 11.6% (27/233) of the dogs and 13% (13/100) of the cats had ocular metastases. Lymphoma was the most common multicentric neoplasm involving the eyes of both species. In dogs, these neoplasms occurred bilaterally, predominantly in the anterior uvea, and were diffuse large B-cell, T-lymphoblastic, peripheral T-cell not otherwise specified, and lymphocytic B-cell lymphomas. In cats, feline leukemia virus (FeLV)-associated T-cell lymphoma was the most common. Mammary carcinoma was the second most common ocular metastatic neoplasm in bitches, with a predominantly unilateral involvement of the uveal tract. In cats, following lymphoma, pulmonary and squamous cell carcinomas were the most common multicentric/metastatic neoplasms of the eyes. Individual cases of cholangiocarcinoma, hemangiosarcoma, and chemodectoma in dogs, as well as mammary gland cribriform carcinoma, salivary gland carcinoma, and histiocytic sarcoma in cats were detected.

CONCLUSIONS

The eyes of dogs were mostly affected by lymphoma or mammary gland carcinoma, while those of cats mostly had lymphoma, pulmonary carcinoma, or squamous cell carcinoma as the main metastatic/multicentric neoplasm. To the best of our knowledge, this is the first study to identify intraocular metastatic cholangiocarcinoma and chemodectoma in dogs, aside from identifying salivary gland carcinoma in cats.

Leptomeningeal metastasis of uterine cervical cancer 17 years after primary tumor treatment

Leptomeningeal metastasis (LM) of uterine cervical cancer is extremely rare. A 54-year-old woman with uterine cervical cancer treated with surgery and radiotherapy developed LM manifesting as ptosis 17 years later. Although rare, LM should be considered in patients with a history of uterine cervical cancer presenting with cranial nerve symptoms.

Optic neuritis as isolated manifestation of leptomeningeal carcinomatosis: a case report and systematic review of ocular manifestations of neoplastic meningitis

Introduction. Leptomeningeal carcinomatosis occurs in about 5% of cancer patients. Ocular involvement is a common clinical manifestation and often the presenting clinical feature. Materials and Methods. We report the case of a 52-year old lady with optic neuritis as isolated manifestation of neoplastic meningitis and a review of ocular involvement in neoplastic meningitis. Ocular symptoms were the presenting clinical feature in 34 patients (83%) out of 41 included in our review, the unique manifestation of meningeal carcinomatosis in 3 patients (7%). Visual loss was the presenting clinical manifestation in 17 patients (50%) and was the most common ocular symptom (70%). Other ocular signs were diplopia, ptosis, papilledema, anisocoria, exophthalmos, orbital pain, scotomas, hemianopsia, and nystagmus. Associated clinical symptoms were headache, altered consciousness, meningism, limb weakness, ataxia, dizziness, seizures, and other cranial nerves involvement. All patients except five underwent CSF examination which was normal in 1 patient, pleocytosis was found in 11 patients, increased protein levels were observed in 16 patients, and decreased glucose levels were found in 8 patients. Cytology was positive in 29 patients (76%). Conclusion. Meningeal carcinomatosis should be considered in patients with ocular symptoms even in the absence of other suggestive clinical symptoms.

Meningeal carcinomatosis from cervical cancer: a case report and review of the literature

Meningeal carcinomatosis (MC) from cervical cancer is rare. Diagnosis of this disease is often delayed due to variable presentation. We report an interesting case of MC from the uterine cervix and review general diagnostic and treatment considerations. The patient received chemotherapy and radiotherapy for stage IIB cervical cancer with resolution of symptoms for 3 years. Metastatic lesions were found in the right lung and paraaotic nodes on follow-up positron emission tomography scan, which completely resolved with subsequent chemotherapy. Unfortunately, the patient developed neurological symptoms consistent with MC, which was confirmed by cerebrospinal fluid cytology. Because of her poor cognition, available options were discussed with her family. She died peacefully in palliative care.

Meningeal carcinomatosis and uterine carcinoma: three different clinical settings and review of the literature

INTRODUCTION

Leptomeningeal carcinomatosis is a rare metastatic event in gynecological neoplasias, and most cases occur in ovarian cancer. It is extremely infrequent in cervical cancer, and so far, there are not any reports of this complication in association with endometrial cancer.

PATIENTS AND METHODS

We report a case of leptomeningeal carcinomatosis secondary to endometrial carcinoma and 2 complex cervix cancer cases. A MEDLINE search was done to review all published cases of this complication in gynecological cancer to identify predictive factors for this diagnosis.

RESULTS AND DISCUSSION

Leptomeningeal carcinomatosis is usually diagnosed late in the course of the disease, and most reports concern ovarian cancer patients. The number of cases describing this neurologic complication in cervix cancer is increasing. Gadolinium-enhanced magnetic resonance imaging may be necessary for this diagnosis, because cerebrospinal fluid analysis results may be negative. Most cervix cases had squamous cell (8/14) or neuroendocrine histologic subtype (3/14), and when reported, differentiation was usually poor. The case we report of endometrial carcinoma, unique in the literature, is a serous adenocarcinoma.

CONCLUSIONS

A high index of suspicion is necessary, and leptomeningeal carcinomatosis should be considered in patients with unexplained neurologic symptoms whose gynecologic tumors are poorly undifferentiated or have a serous component.

Leptomeningeal metastasis in a patient with squamous cell carcinoma of the uterine cervix: Report of a case and review of the literature

Leptomeningeal spread of advanced squamous cell carcinoma (SCC) of the uterine cervix is unusual. To our knowledge, very few cases were reported in the English literature. We report a case of a 39-yr-old woman who presented with leptomeningeal metastasis from a stage IIb SCC of uterine cervix. The diagnosis was made by cytomorphological examination of smears obtained from cerebrospinal fluid. The cytomorphological features are demonstrated.
