Apart from choriocarcinoma, involvement of the central nervous system (CNS) by gynecologic malignancy is rare. A 10-year retrospective review at the University of Washington Medical Center (Seattle, WA) and Swedish Hospital and Medical Center Tumor Registry (Seattle, WA) identified 14 patients with cerebral metastases from ovarian carcinoma. Median age at diagnosis of cerebral metastases was 52.5 years. Median interval from the diagnosis of ovarian carcinoma to the diagnosis of CNS metastases was 14.5 months. Seven patients had received cisplatin therapy before CNS relapse. Seven patients underwent second-look procedures before developing CNS metastases; in three, results were negative. Eight patients had evidence of extraperitoneal spread to other sites at the time of CNS relapse. Clinical manifestations included motor weakness, seizures, headache, confusion, and speech disturbance. All lesions were contrast enhancing on computed tomography (CT) scans and were located in the cerebral hemispheres. Nine patients had single lesions, five of whom underwent surgical resection of the lesion with histologic confirmation of metastases from the primary site. Median survival was 2 months in patients receiving radiation therapy alone and 17 months in patients who received surgery and radiation. Median survival of the entire series was 3 months. The presence of multiple cerebral metastases or evidence of extraperitoneal spread elsewhere in the body was adversely associated with survival. The prognosis of patients with cerebral metastases from ovarian carcinoma appears poor. However, early diagnosis by routine CT scanning followed by surgical resection and radiation may improve overall survival in a select group of patients.

Central nervous system (CNS) involvement by endometrial carcinoma is uncommon. Among 1069 patients registered for endometrial carcinoma at our institution between 1982 and 1994, 10 (0,9%) developed brain metastases. Median age at the time of CNS metastasis diagnosis was 59 years. Median interval between diagnosis of endometrial cancer and documentation of brain involvement was 26 months. Clinical manifestation of brain metastasis included headache (80%), motor weakness (50%), seizures (20%), confusion (10%), balance (10%), and visual disturbances (10%). All lesions (4 multiple, 6 single) were contrast enhancing on computed tomography (CT) scans, and were located in the cerebrum in seven cases, in the cerebellum in one case, and in both in two cases. The CNS was the only site of detectable disease in six patients with recurrent disease. Nine patients died and one is alive with disease 3 months after surgical resection of a single cerebral deposit. Median survival from diagnosis of brain metastases for the entire series was 1 month (range 1-83). Six patients receiving only steroids died within 1 month from the diagnosis. One patient received radiotherapy (survival, 3 months) and two underwent surgical resection of solitary metastasis followed by radiotherapy (survival = 28 and 83 months). Prognosis of patients with CNS metastases from endometrial carcinoma appears poor; however, in a selected group of patients early diagnosis followed by multimodal treatment may result in a palliation of the disease.

Central nervous system (CNS) involvement by cervical carcinoma is uncommon. Out of 1,184 patients registered for invasive cervical carcinoma at our institution between 1982 and 1994, 14 (1.18%) developed brain metastases. Median age at the time of CNS metastasis diagnosis was 52 years. Median interval between diagnosis of cervical cancer and documentation of brain involvement was 18 months. Clinical manifestation included motor weakness, headache, seizures, dizziness and visual disturbances. All lesions (8 multiple, 6 single) were contrast enhanced on computerized tomography scans and were located in the cerebrum (n = 10), in the cerebellum (n = 2), or in both (n = 2). The CNS was the only site of detectable disease in 7 patients with recurrent disease. Eleven patients received only steroids, and 3 patients received radiotherapy. All 14 patients died, and median survival from diagnosis of brain metastases for the entire series was 4 months (range, 1-21). CNS metastases from cervical cancer are rare, and the prognosis for such patients appears poor.

Metastatic spread of tumour cells detached from melanoma into the central nervous system (CNS) occurs haematogenously since lymphatic drainage is absent in the brain. CNS metastases occur in 10 to 40% of melanoma patients in clinical studies and up to 90% in autopsy studies. Headache is the most common presenting symptom, but brain metastases should be suspected in all melanoma patients with new neurologic findings. Magnetic resonance imaging is the best diagnostic technique for detecting CNS metastases. Median survival of melanoma patients with CNS metastases ranges between 2 and 8 months. The optimal treatment of melanoma patients with CNS metastases depends on the objective situation, often surgery, radiosurgery, whole brain radiotherapy and chemotherapy are used in combination to obtain longer remissions and optimal symptom relieve.

Leptomeningeal metastasis (LM), i.e. the seeding of tumor cells to the cerebrospinal fluid (CSF) and the leptomeninges, is a devastating and mostly late-stage complication of various solid tumors. Clinical signs and symptoms may include cranial nerve palsies, radicular symptoms, signs of increased intracranial pressure such as headache, nausea and vomiting, and cognitive dysfunction. In cases of suspected LM, the highest diagnostic sensitivity is provided by the combination of CSF cytology and contrast-enhanced MRI (cranial as well as complete spine). The therapeutic spectrum includes radiotherapy of the clinically involved region as well as systemic and intrathecal chemotherapy. The choice of treatment modalities depends on the type of LM (non-adherent tumor cells in the CSF vs. nodular contrast-enhancing tumor growth), additional systemic involvement (uncontrolled vs. controlled systemic disease) and additional involvement of the CNS parenchyma (LM as the only CNS involvement vs. LM+parenchymal CNS metastases). Larger contrast-enhancing nodular LM or symptomatic lesions of the spine may be treated with radiotherapy. In case of uncontrolled systemic disease, the treatment regimen should include systemic chemotherapy. The choice of systemic treatment should take into account the histology of the primary tumor. Intrathecal chemotherapy is most important in cases of LM of the non-adherent type. There are three substances for routine use for intrathecal chemotherapy: methotrexate, cytarabine, and thiotepa. Liposomal cytarabine shows advantages in terms of longer injection intervals, a sufficient distribution in the entire subarachnoid space after lumbar administration and improved quality-of-life. The role of new agents (e.g. rituximab and trastuzumab) for intrathecal therapy is still unclear.

The incidence of brain metastases is projected to rise because survival rates of lung cancer, breast cancer, and melanoma continue to improve (1). The brain is being identified as a sanctuary site for harboring metastases despite excellent control of extracranial disease. This is thought to occur because the drug therapies that control extracranial disease have limited central nervous system (CNS) penetration. The development of brain metastases is a devastating diagnosis affecting both quality of life (QOL) and survival. Symptoms after diagnosis can include headache, nausea, vomiting, seizure, neurocognitive decline, and focal neurologic deficit. Some of these symptoms can be irreversible even after successful treatment of intracranial disease. Treatment of brain metastases often necessitates surgery and radiation. There have been some reports of systemic therapies offering an intracranial response however long-term data is lacking. These treatments for CNS metastases can also lead to neurocognitive sequelae impacting quality of life. Therefore, preventing disease from spreading to the brain is a topic that has generated much interest in oncology. Prophylactic cranial Irradiation (PCI) has been used in leukemia, small cell lung cancer (SCLC), and non-small cell lung cancer (NSCLC). While showing effectiveness in preventing intracranial disease development, its carries with it side effects of neurocognitive decline that can affect QOL. There are Clinical trials exploring novel delivery of PCI and concurrent neuroprotective drug therapy to try to mitigate these neurocognitive sequelae. These will be important trials to complete, as PCI has shown promise in controlling disease and prolonging survival in select patient populations. There are also drug therapies that have shown efficacy in preventing CNS metastases development. This review will explore the current therapies available to prevent CNS metastases.

The development of brain and central nervous system (CNS) metastases from primary gynecologic cancers is an extremely uncommon but deadly process. Through this retrospective case series of patients treated at a single institution from 2004 to 2018, we aim to explore potential clinical patterns of this phenomenon with respect to primary tumor type, histology, and symptomatology. A total of 42 patients were identified with CNS metastases, with 24 patients having endometrial cancer, 9 patients with ovarian cancer, 5 patients with cervical cancer, and 4 patients with gestational trophoblastic neoplasia (GTN). The two most common presenting complaints were headache and ataxia. Most patients (67%) presented with more than one lesion on imaging and the frontal lobe was most likely to be involved. The median age of diagnosis for both primary cancer and CNS metastasis were significantly younger in the GTN group when compared to other cancers. Meningeal involvement was more prevalent in patients with cervical cancer. Over 83% of endometrial cancer patients in this cohort had type II histologies, a significantly higher percentage than that in the general population. While the rarity of CNS metastases in primary gynecologic malignancies precludes routine screening, patients diagnosed with more aggressive histologic subtypes of endometrial and uterine cancers may benefit from a lowered threshold of brain imaging in the context of new onset neurological symptoms.

The abscopal effect is a term that has been used to describe the phenomenon in which localized radiation therapy treatment of a tumor lesion triggers a spontaneous regression of metastatic lesion(s) at a non-irradiated distant site(s). Radiation therapy induced abscopal effects are believed to be mediated by activation and stimulation of the immune system. However, due to the brain's distinctive immune microenvironment, extracranial abscopal responses following cranial radiation therapy have rarely been reported. In this report, we describe the case of 42-year-old female patient with metastatic melanoma who experienced an abscopal response following her cranial radiation therapy for her brain metastasis. The patient initially presented with a stage III melanoma of the right upper skin of her back. Approximately 5 years after her diagnosis, the patient developed a large metastatic lesion in her upper right pectoral region of her chest wall and axilla. Since the patient's tumor was positive for BRAF and MEK, targeted therapy with dabrafenib and trametinib was initiated. However, the patient experienced central nervous system (CNS) symptoms such as headache and disequilibrium and developed brain metastases prior to the start of targeted therapy. The patient received radiation therapy to a dose of 30 Gy delivered in 15 fractions to her brain lesions while the patient was on dabrafenib and trametinib therapy. The patient's CNS metastases improved significantly within weeks of her therapy. The patient's non-irradiated large extracranial chest mass and axilla mass also shrank substantially demonstrating the abscopal effect during her CNS radiation therapy. Following radiation therapy of her residual chest lesions, the patient was disease free clinically and her CNS lesions had regressed. However, when the radiation therapy ended and the patient continued her targeted therapy alone, recurrence outside of her previously treated fields was noted. The disease recurrence could be due to the possibility of developing BRAF resistance clones to the BRAF targeted therapy. The patient died eventually due to wide spread systemic disease recurrence despite targeted therapy.

Central nervous system (CNS) metastases occur frequently in oncogene-driven non-small cell lung cancer (NSCLC). Standard treatment approaches can potentially delay systemic treatment (surgical intervention) or result in neurocognitive impairment (radiotherapy). Recently, next-generation tyrosine kinase inhibitors (TKIs) have demonstrated remarkable intracranial activity. However, most clinical trials did not enroll patients suffering neurological symptoms. Our study aimed to assess the CNS activity of targeted therapies in this patient population. We present a case series of nine NSCLC patients with either EGFR mutation or ALK rearrangement and symptomatic CNS metastases that were treated with TKIs. Clinicopathological characteristics, treatment, and outcomes were analyzed. Most patients presented with symptomatic CNS metastases at time of metastatic disease presentation (6/9). Additionally, the majority of patients had leptomeningeal disease (6/9) and multiple parenchymal metastases. Patients presented with a variety of CNS symptoms with the most common being nausea, vomiting, headache, and confusion. Most patients (6/9) responded rapidly both clinically and radiographically to the targeted treatment, with a marked correlation between systemic and intracranial radiographic response. In conclusion, upfront use of next-generation TKIs in patients with oncogene-driven NSCLC with symptomatic CNS metastases is associated with reasonable intracranial activity and represents a valuable treatment option.
