Abstract
Brain metastases (BMs) arising from ovarian cancer remain rare. Spinal cord metastases are even rarer, accounting for just 0.4% of total metastatic spinal cord compressions. In this report, we describe a case of a woman in her 70s who developed sequential brain and spinal cord metastases during her treatment for high-grade serous ovarian cancer, without a germline or somatic BRCA mutation. Following completion of neoadjuvant chemotherapy, interval debulking surgery and adjuvant chemotherapy, relapsed disease was ultimately identified as a single BM, curiously mimicking an acoustic neuroma. Subsequently, spinal cord metastases rapidly developed. Throughout, multidisciplinary team meetings guided decisions on patient management. In this report, we highlight the rarity of such a presentation and discuss the possible role of disease pathophysiology, associated systemic anticancer therapy resistance, and treatment possibilities for both cerebral and spinal metastases.

Description of a Retrospective Cohort of Epithelial Ovarian Cancer Patients with Brain Metastases: Evaluation of the Role of PARP Inhibitors in this Setting. J Clin Med 2023; 12:jcm12072497. [PMID: 37048581 PMCID: PMC10095324 DOI: 10.3390/jcm12072497] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 02/28/2023] [Accepted: 03/15/2023] [Indexed: 03/29/2023] Open
Abstract
Background: The incidence of brain metastases (BM) in patients with epithelial ovarian cancer (EOC) is low: 0.3–11%. The onset of BM has been regarded as a late event with limited treatment options and poor prognosis. This retrospective case series aims to explore the current management strategies with particular emphasis on the use of PARP inhibitors and outcomes, as well as identification of other prognostic indicators. Methods: A total of 39 ovarian cancer patients with brain metastases were identified from eight cancer centres in the UK. Clinical characteristics, details of management, and survival data were collected. Results: A total of 14/39 had BM as their first site of relapse. The majority (29 patients) received systemic treatments in addition to local radiotherapy (RT)/surgery. Nineteen patients had BRCA mutations (one somatic), one had a RAD51C mutation, and eighteen were BRCA wild type; one was unknown. A total of 14/39 patients received maintenance PARP inhibitors. As is well known, patients who received PARPi had consistently better outcomes. This was no different for those who received PARPi as part of the management of their BM. Platinum sensitivity and receiving more than one modality of therapy (e.g., radiation +/− chemotherapy and PARPi) for BM were also good prognostic indicators. Median PFS/OS for those treated with chemotherapy and either RT or surgery, then PARP inhibitor maintenance, have not been reached after a median of 33 months follow up. Conclusions: As with abdominal relapse, maintenance treatment with PARP inhibitors also has a valuable role in managing BMs in EOC patients.

Abstract
Management of central nervous system (CNS) metastases from epithelial ovarian cancer (EOC) is an unmet need. We analyzed data on 41 such patients to evaluate predictors of outcome. Between January, 2010 and December 2020, among 1028 patients with EOC treated at our institute 41 (3.98%) developed CNS metastasis. Median age of patients was 48 years, ranging from 22 to 75 years. Primary outcome measure was progression free survival (PFS). Overall survival (OS), and analysis of prognostic factors were secondary outcome measures. An intention to treat analysis was done. We also performed review the literature (n=2253) as regards to clinicopathological and radiological features, treatment received, survival outcomes and prognostic factors. Median time from diagnosis of EOC to CNS metastasis was 27 months (range: 0 to 101 months). 33(80.5%) patients had FIGO stage III-IV at baseline and serous carcinoma (75.6%) was common pathology subtype. Thirteen (31.7%) patients had isolated CNS metastasis and 28 (68.3%) had intra-abdominal disease in addition. Nineteen (46.3%) patients achieved complete response post treatment with surgery, radiation and chemotherapy. Median PFS and OS from the time of CNS metastasis is 12 (range:1 to 51) months and 33 (range: 1 to 71) months, respectively. Absence of extracranial disease and lower serum CA-125 at diagnosis of CNS metastasis were predictive of superior PFS and OS on multivariate analysis. CNS metastasis is a late event in EOC, post multiple lines of treatment. Patients with disease limited to brain and treated with surgical resection and chemoradiation have best outcome.

Abstract
Ovarian carcinoma is a common malignancy with a grim prognosis and a high mortality rate. Here, we report a rare case of an Iranian woman with four episodes of recurrent metastatic ovarian carcinoma. She was initially diagnosed with stage IVa high-grade serous ovarian adenocarcinoma (HGSOC), treated with paclitaxel-carboplatin and capecitabine, followed by total abdominal hysterectomy and bilateral salpingo-oophorectomy. Two years later, she developed cerebellar metastasis and received whole-brain radiotherapy and paclitaxel-carboplatin. Eighteen months later, she had peritoneal metastasis and had sequential gemcitabine-carboplatin-paclitaxel. One year later, she had splenic metastasis, treated with splenectomy and adjuvant carboplatin and nano-albumin bond paclitaxel. The patient remains in remission until now, 11 months after completing the most recent regimen. This report emphasizes the potential to successfully use chemoradiotherapy with sequential courses of platinum-based agents in patients with recurrent metastatic HGSOC.

Abstract
Central nervous system (CNS) metastases from epithelial ovarian cancer (EOC) are rare. We investigated the clinico-pathological prognostic factors of patients with CNS metastases from EOC and compared the outcomes of various treatment modalities. We retrospectively reviewed the records of patients with CNS metastases from EOC between 2000 and 2020. Information on the clinical and pathological characteristics, treatment, and outcomes of these patients was retrieved from Samsung Medical Center and National Taiwan University Hospital. A total of 94 patients with CNS metastases were identified among 6,300 cases of EOC, resulting in an incidence of 1.49%. Serous histological type [hazard ratio (HR): 0.49 (95% confidence interval [CI] 0.25-0.95), p=0.03], progressive disease [HR: 2.29 (95% CI 1.16-4.54), p=0.01], CNS involvement in first disease relapse [HR: 0.36 (95% CI 0.18-0.70), p=0.002], and gamma knife radiosurgery (GKS)-based combination treatment for EOC patients with CNS lesions [HR: 0.59 (95% CI 0.44-0.79), p<0.001] significantly impacted survival after diagnosis of CNS metastases. In a subgroup analysis, superior survival was observed in patients with CNS involvement not in first tumor recurrence who underwent GKS-based combination therapeutic regimens. The survival benefit of GKS-based treatment was not significant in patients with CNS involvement in first disease relapse, but a trend for longer survival was still observed. In conclusion, GKS-based combination treatment can be considered for the treatment of EOC patients with CNS metastases. The patients with CNS involvement not in first disease relapse could significantly benefit from GKS-based combination strategies.

Abstract
OBJECTIVE Brain metastasis from epithelial ovarian carcinoma (EOC) is rarely seen having rate of 1-3% with very poor prognosis. Studies on brain metastatic EOC is limited with low number of participants. An increasing trend in EOC related to brain metastasis has been reported recently confronting managing clinicians with new challenges. Therefore, more information on this issue is needed. We aimed to analyze a single radiotherapy center experience on EOC related brain metastases. MATERIALS AND METHODS Data of all patients treated between January 1998 and December 2016 at a radiation center of a university hospital were reviewed retrospectively. Clinicopathological characteristics, treatment details and outcome were analyzed. RESULTS We identified only ten cases with EOC related brain metastasis in our department during 18-year period. Two patients were excluded because of data unavailability and therefore our study was performed among 8 patients. The median time between EOC diagnosis and detection of brain metastasis was 19.8 months. Brain metastasis was multiple in majority (75%). Extracranial metastasis at the time of brain metastasis was 62.5%. All patients died in the follow-up. The median survival time after the diagnosis of brain metastasis was 4.5 months. The median overall survival (OS) after the diagnosis of EOC was 28.9 months. The interval between the initial diagnosis and brain metastasis was negatively correlated with survival after brain metastasis (B-OS) occurred as time interval (p = 0.047). Presence of extracranial metastasis at time of occurrence of brain metastasis and application of multimodal treatment after brain metastasis were positively correlated with B-OS time (p = 0.007, p = 0.046, respectively). CONCLUSION Prognosis of brain metastasis from EOC remains poor. The factors associated with better B-OS were the longer time between initial diagnosis and brain metastasis, absence of extracranial disease at time of brain metastasis, and application of the multimodal treatment.

Abstract
With this review, we provide the state of the art concerning brain metastases (BMs) from ovarian cancer (OC), a rare condition. Clinical, pathological, and molecular features, treatment options, and future perspectives are comprehensively discussed. Overall, a diagnosis of high-grade serous OC and an advanced disease stage are common features among patients who develop brain metastases. BRCA1 and BRCA2 gene mutations, as well as the expression of androgen receptors in the primary tumor, are emerging risk and prognostic factors which could allow one to identify categories of patients at greater risk of BMs, who could benefit from a tailored follow-up. Based on present data, a multidisciplinary approach combining surgery, radiotherapy, and chemotherapy seem to be the best approach for patients with good performance status, although the median overall survival (<1 year) remains largely disappointing. Hopefully, novel therapeutic avenues are being explored, like PARP inhibitors and immunotherapy, based on our improved knowledge regarding tumor biology, but further investigation is warranted.

Abstract
Aims and Objectives To review a series of patients with brain metastases from ovarian cancer at a single institution. To describe treatment modalities, their outcomes and to determine prognostic factors. Patients and Methods Between January 1995 and December 2014, 25 patients with ovarian cancer brain metastases were treated at The Sheba Medical Center. The medical records were retrospectively reviewed to collect demographic, clinical, and imaging data as well as the information on the treatment modalities used and their outcomes. Results Mean patient age at the time of brain metastasis diagnosis was 62.7 years. The median interval between the diagnosis of primary cancer and brain metastasis was 42.3 months. Neurologic deficits, headache, and seizure were the most common symptoms. The brain was the only site of metastasis in 20% of the patients. Active ovarian cancer at the time of diagnosis of brain metastasis was observed in half of the patients with systemic disease. Multiple brain metastases were observed in 25% of the patients. We treated 11 patients with surgery plus radiation therapy protocols in various orders: surgery followed by complementary whole-brain radiation therapy (WBRT), surgery followed by stereotactic radiosurgery (SRS), and surgery followed by WBRT and then by adjuvant SRS. Five patients underwent surgery alone and nine patients were treated with radiation alone (WBRT, SRS, or both). Univariate analysis for predictors of survival demonstrated that age above 62.7 years at the time of central nervous system involvement was a significant risk factor and leptomeningeal disease was a poor prognostic factor in reference to supra-tentorial lesions. Multivariate analysis for predictors of survival, however, showed that multiple brain lesions (>4) were a poor prognostic factor, and multivariate analysis of the time to progression revealed that combined treatments of surgery and radiation resulted in longer median periods of progression-free survival than each modality alone. Conclusion We conclude that the only significant predictors of survival or progression-free survival in our cohort were the number of brain metastases and the treatment modality.

Abstract
Ovarian cancer with solitary metastasis to the cerebellum is very rare. We presented a 58-year-old woman complaining of headaches 9 months after debulking surgery and chemotherapy due to ovarian cancer. The serum CA125 level was elevated. FDG PET/CT was then recommended to identify potential malignancy and showed a hypermetabolic mass in the right cerebellum. The cerebellar mass was surgically removed, and the pathology confirmed metastasis from ovarian cancer.

Abstract
Background Brain metastasis (BM) is a rare event in ovarian cancer patients. The current prognostic scores that have been used for other tumors do not account for specific characteristics of ovarian cancer, such as platinum sensitivity. Methods This retrospective cohort study examined patients with ovarian carcinoma and BM who were treated at a single institution from January 2007 to December 2017. Clinical data on the diagnosis of BM and follow-up were collected. Cox regression was used to evaluate prognostic factors for overall survival (OS). Results Of 560 patients, 26 presented with BM. Eight patients were treated with surgery, 15 with whole-brain radiotherapy (RT), and 5 with stereotactic RT, and 4 patients received systemic treatment at the diagnosis of BM. The median OS was 10.8 months. The following factors were associated with OS: platinum-sensitive recurrence (HR 0.34, 95% CI 0.12–0.99; p = 0.049), higher number of previous treatment lines (HR 1.57, 95% CI 1.12–2.19; p = 0.008), ECOG performance status (HR 2.52, 95% CI 1.24–5.09; p = 0.010), and longer interval from initial diagnosis to BM (p = 0.025). Notably, the number of brain metastasis, the largest tumor size, and progression outside of the CNS were not related to survival. Platinum sensitivity was not associated with any of the classic prognostic factors in brain metastasis patients such as number or size of brain metastasis or disease progression outside the CNS strengthening the hypothesis of the importance of platinum sensitivity to the prognosis of ovarian cancer patients with BM. Conclusions The factors related to the biological behavior of the ovarian cancer such as platinum sensitivity at the time of BM diagnosis, fewer number of previous treatment lines and interval from initial diagnosis were associated with survival in ovarian cancer patients with BM, while factors that are usually related to survival in BM in other cancers were not associated with survival in this cohort of ovarian cancer patients. The small number of patients did not allow us to exclude the prognostic role of these former factors that were not associated with survival in the present cohort.

Abstract
OBJECTIVES The most appropriate treatments for brain metastases from ovarian cancer have not been established mainly because of its rarity. The objective of this study was to describe clinical results of treatment and prognostic factors of patients with brain metastases from ovarian cancer treated at a single institution. MATERIALS AND METHODS We retrieved information from the electronic medical records of 56 consecutive patients (2.8%) with brain metastases, from a total of 2008 patients with ovarian cancer. Endpoints were the pattern of treatment failure, progression-free survival, and overall survival (OS). RESULTS Radiation was the most common initial treatment for brain metastases (59%), followed by surgery (23%). The median progression-free survival was 9.8 months. Radiological progression was confirmed in 20 patients: 7 had leptomeningeal carcinomatosis (37%), 8 had local recurrence, and 5 had distant recurrence. Median OS was 11.25 months, and the 1-year OS rate was 48.2%. Patients received surgery for single metastasis as initial treatment showed median OS of 24.1 months, which was significantly prolonged compared with the other patients (P = 0.0002). Of the 48 patients who died, 29 (60%) died of systemic disease and 7 (15%) died of central nervous system progression. Karnofsky Performance Status greater than or equal to 70, control of systemic cancer, serous histology, and surgery for brain metastases were associated with improved OS in multivariable analysis (P < 0.05). CONCLUSIONS Surgical resection for single or symptomatic brain metastases from ovarian cancer prolonged OS significantly. Multimodality treatment, including control of systemic cancer, appeared to be an important factor in prolonging OS.

Abstract
OBJECTIVE Gynecological brain metastases (BM) are rare and usually develop as part of widespread disseminated disease. Despite treatment, the majority of these patients do not survive > 1 year due to advanced extracranial disease. The use of Gamma Knife Radiosurgery (GKRS) for gynecological BM is not well known. The goal of this study is to evaluate the efficacy of GKRS for gynecological BM. METHODS We performed a retrospective study of patients with gynecological BM who underwent GKRS between 2002 and 2015. A total of 41 patients were included. Outcome measures were local tumor control (LC), development of new BM and/or leptomeningeal disease, overall intracranial progression free survival (PFS) and survival. RESULTS LC was 100%, 92%, 80%, 75% and 67% at 3, 6, 9, 12 and 15 months, respectively. PFS was 90%, 61%, 41%, 23% and 13% at 3, 6, 9, 12 and 15 months, respectively. During follow-up (FU), 18 (44%) patients had intracranial progression. Distant BM occurred in 29% of the patients. Local recurrence and distant recurrence occurred after a mean FU time of 15.5 (2.6-71.9) and 11.4 (2-40) months, respectively. Thirty-one (76%) patients died due to extracranial tumor progression and only 2 (5%) patients died due to progressive intracranial disease. The overall mean survival from time of GKRS was 19 months (1-109). The 6-month, 1-year, and 2-year survival rate from the time of GKRS were 71%, 46%, and 22%, respectively. CONCLUSION GKRS is a good treatment option for controlling gynecological BM. As most patients die due to extracranial tumor progression, their survival might improve with better systemic treatment options in addition to GKRS.

Abstract
A 68-year-old woman presented with a three-week history of confusion and anomic aphasia. Imaging of her head demonstrated a single large left frontal mass. Pathology revealed metastatic adenocarcinoma of Müllerian origin. Subsequent surgery revealed a small primary site in a fallopian tube, high left para-aortic lymphadenopathy, and no disseminated intraperitoneal disease. This case was remarkable in that CNS metastasis was her presenting symptom and was restricted to a solitary brain lesion, and other disease sites were limited to retroperitoneal lymphadenopathy and a small fallopian tube primary.

Abstract
BACKGROUND Brain metastases (BM) from epithelial ovarian cancer (EOC) are considered a rare and unfavourable event. There is no consensus regarding the best management of these patients. METHODS A multicenter retrospective analysis of patients with BM from EOC treated between 1997 and 2014 in 18 institutions of the MITO (Multicenter Italian Trials in Ovarian cancer) group was conducted. Univariate and multivariate analysis were performed. RESULTS A total of 174 women were identified as having BM from EOC. The median time interval between primary diagnosis of EOC and occurrence of BM was 26months (range 2-129months). The median overall survival from primary EOC diagnosis was 48months (95% CI 39.5-56.4months) and from diagnosis of BM was 12months (95% CI 9.6-14.3months). The majority of enrolled women (81.7%) were classified as sensitive to platinum-based chemotherapy. Four variables were significantly associated with poor overall survival in multivariate analysis: multiple BM [HR: 1.86 (95% CI: 1.22-2.84)], presence of extracranial disease [HR: 1.77 (95% CI: 1.11-2.83)] age [HR: 1.74 (95% CI: 1.17-2.59)], and monotherapy [HR: 2.57 (95% CI: 1.64-3.86)]. On the contrary, residual tumor at primary surgery, FIGO stage at primary diagnosis and platinum sensitivity were found to have no significant impact on survival from diagnosis of brain lesions. CONCLUSIONS Our results suggest that BM is a rare and late manifestation of EOC, with a 12-month life-span expectation. Multiple approach is a positive independent prognostic factor and should be proposed to carefully selected patients.

Abstract
OBJECTIVE The reported incidence of brain metastasis from epithelial ovarian cancer (EOC), endometrial cancer (EC), and cervical cancer (CC) is exceedingly rare. As the long-term survival for patients with gynecologic cancer increases, there has been a corresponding increase in the number of diagnosed intracranial metastases. We seek to report our experience with managing brain metastatic disease (BMD) in patients with gynecologic cancer. METHODS A retrospective review of all patients with EOC, EC, and CC at our institution revealed 47 patients with concurrent BMD between 2000 and 2013. Demographic data, risk factors, treatment modalities, progression-free data, and overall survival data were collected. RESULTS Median survival time in patients with brain metastasis from EOC, EC, and CC was 9.0, 4.5, and 3.0 months, respectively. Two-year overall survival rates were 31.6%, 13.6%, and 0%, respectively. Patients received surgery, radiation therapy alone, palliative care, or radiation plus surgery. Radiation combined with surgical resection resulted in a significant hazards ratio of 0.36 (95% confidence interval, 0.15-0.86), compared with radiation alone. CONCLUSIONS Our report provides a large single-institution experience of brain metastases from gynecologic cancer. Patients with BMD have poor prognoses; however, treatment with multimodal therapy including surgical resection and radiation may prolong overall survival.

Abstract
Brain metastases occur in about 10% to 30% of breast cancer patients, which culminates in a poor prognosis. It is, therefore, critical to understand the molecular mechanisms underlying brain metastatic processes to identify relevant targets. We hypothesized that breast cancer cells must express brain-associated markers that would enable their invasion and survival in the brain microenvironment. We assessed a panel of brain-predominant markers and found an elevation of several neuronal markers (βIII-tubulin, Nestin, and AchE) in brain metastatic breast cancer cells. Among these neuronal predominant markers, in silico analysis revealed overexpression of βIII-tubulin (TUBB3) in breast cancer brain metastases (BCBM) and its expression was significantly associated with distant metastases. TUBB3 knockdown studies were conducted in breast cancer models (MDA-Br, GLIM2, and MDA-MB-468), which revealed significant reduction in their invasive capabilities. MDA-Br cells with suppressed TUBB3 also demonstrated loss of key signaling molecules such as β3 integrin, pFAK, and pSrc in vitro. Furthermore, TUBB3 knockdown in a brain metastatic breast cancer cell line compromised its metastatic ability in vivo, and significantly improved survival in a brain metastasis model. These results implicate a critical role of TUBB3 in conferring brain metastatic potential to breast cancer cells.

Abstract
Background To characterize prognostic and risk factors of central nervous system (CNS) metastases in patients with epithelial ovarian cancer (EOC). Methods A retrospective analysis of Xijing Hospital electronic medical records was conducted to identify patients with pathologically confirmed EOC and CNS metastases. In addition to patient demographics, tumor pathology, treatment regimens, and clinical outcomes, we compared putative cancer stem cell marker CD133 expression patterns in primary and metastatic lesions as well as in recurrent EOC with and without CNS metastases. Results Among 1366 patients with EOC, metastatic CNS lesions were present in 29 (2.1%) cases. CD133 expression in primary tumor was the only independent risk factor for CNS metastases; whilst the extent of surgical resection of primary EOC and platinum resistance were two independent factors significantly associated with time to CNS metastases. Absence of CD133 expression in primary tumors was significantly associated with high platinum sensitivity in both patient groups with and without CNS metastases. Platinum resistance and CD133 cluster formation in CNS metastases were associated with decreased survival, while multimodal therapy including stereotactic radiosurgery (SRS) for CNS metastases was associated with increased survival following the diagnosis of CNS metastases. Conclusions These data suggest that there exist a positive association between CD133 expression in primary EOC, platinum resistance and the increased risk of CNS metastases, as well as a less favorable prognosis of EOC. The absence of CD133 clusters and use of multimodal therapy including SRS could improve the outcome of metastatic lesions. Further investigation is warranted to elucidate the true nature of the association between platinum sensitivity, CD133 expression, and the risk and prognosis of CNS metastases from EOC.

Abstract
Background Brain metastasis from epithelial ovarian cancer (EOC) is very rare with a reported incidence of less than 2%. It is usually associated with a poor prognosis that is related to several factors, the most important including: single vs multiple lesions, performance status, platinum-sensitive disease, tumor grade, extracranial disease, and multimodal approach treatment. At the time of diagnosis, an extracranial disease is found in over half of patients. The most common histology is the serous type. The median time from primary diagnosis to development of cerebral lesions is directly correlated to initial tumor grade and stage. Several therapeutic approaches can be proposed, including best supportive care +/- corticosteroids, surgery, radiotherapy and chemotherapy. A multimodal therapy approach may achieve an improved outcome and should therefore be utilized whenever applicable. Case presentation We present the case of a patient with a solitary brain metastasis which appeared 11 years after a locally advanced and aggressive EOC (FIGO stage III C) and which totally regressed after surgery and adjuvant chemotherapy. Clinically, she showed progressive headaches, decreased visual acuity, balance and memory disorders associated with a confusional state. Brain CT scan and MRI documented a solitary, necrotic lesion in the left central parietal region with an important cerebral surrounding edema and initial cranial herniation. No other extracranial metastases were observed at the PET scan. Laboratory tests were in the normal range and CA 125 was moderatly increased at 81 UI/ml. The patient underwent surgical removal of tumor lesion, post-surgical whole-brain radiotherapy (WBRT) and systemic chemotherapy with carboplatin alone for six cycles. At a follow-up of 13 months, she is alive, in good clinical condition and tumor progression free. Conclusion The peculiarity of this case relies on the isolated brain relapse of a BRCA-1/BRCA-2 non-mutated EOC, which is uncommon and rare, and to the very long time, of 11 years, from diagnosis of primary cancer and development of brain metastasis. A multimodal, aggressive approach of this isolated brain metastasis led to a complete and prolonged tumor control.

Abstract
To review the existing literature on brain metastasis (BM) from ovarian cancer and to assess the frequency, anatomical, clinical and paraclinical information and factors associated with prognosis. Ovarian cancer is a rare cause of brain metastasis with a recently reported increasing prevalence. Progressive neurologic disability and poor prognosis is common. A comprehensive review on this subject has not been published previously. This systematic literature search used the Pubmed and Yale library. A total of 66 publications were found, 57 of which were used representing 591 patients with BM from ovarian cancer. The median age of the patients was 54.3 years (range 20-81). A majority of patients (57.3 %) had multiple brain lesions. The location of the lesion was cerebellar (30 %), frontal (20 %), parietal (18 %) and occipital (11 %). Extracranial metastasis was present in 49.8 % of cases involving liver (20.7 %), lung (20.4 %), lymph nodes (12.6 %), bones (6.6 %) and pelvic organs (4.3 %). The most common symptoms were weakness (16 %), seizures (11 %), altered mentality (11 %) visual disturbances (9 %) and dizziness (8 %). The interval from diagnosis of breast cancer to BM ranged from 0 to 133 months (median 24 months) and median survival was 8.2 months. Local radiation, surgical resection, stereotactic radiosurgery and medical therapy were used. Factors that significantly increased the survival were younger age at the time of ovarian cancer diagnosis and brain metastasis diagnosis, lower grade of the primary tumor, higher KPS score and multimodality treatment for the brain metastases. Ovarian cancer is a rare cause of brain metastasis. Development of brain metastasis among older patients and lower KPS score correlate with less favorable prognosis. The more prolonged survival after using multimodality treatment for brain metastasis is important due to potential impact on management of brain metastasis in future.

Abstract
OBJECTIVE To explore the impact of treatment modality on survival in patients with brain metastases from epithelial ovarian cancer. METHODS We conducted a retrospective review of cases of ovarian cancer with brain metastases treated at institutions in three countries (Canada, China, and India) and conducted a search for studies regarding brain metastases in ovarian cancer reporting survival related to treatment modality. Survival was analyzed according to treatment regimens involving (1) some form of surgical excision or gamma-knife radiation with or without other modalities, (2) other modalities without surgery or gamma-knife radiation, or (3) palliation only. RESULTS Twelve patients (mean age 56 years) with detailed treatment/outcome data were included; five were from China, four from Canada, and three from India. Median time from diagnosis of ovarian cancer to brain metastasis was 19 months (range 10 to 37 months), and overall median survival time from diagnosis of ovarian cancer was 38 months (13 to 82 months). Median survival time from diagnosis of brain metastasis was 17 months (1 to 45 months). Among patients who had multimodal treatment including gamma-knife radiotherapy or surgical excision, the median survival time after the identification of brain metastasis was 25.6 months, compared with 6.0 months in patients whose treatment did not include this type of focused localized modality (P = 0.006). Analysis of 20 studies also indicated that use of gamma-knife radiotherapy and excisional surgery in multi-modal treatment resulted in improved median survival interval (25 months vs. 6.0 months, P < 0.001). CONCLUSION In the subset of patients with brain metastases from ovarian cancer, prolonged survival may result from use of multidisciplinary therapy, particularly if metastases are amenable to localized treatments such as gamma-knife radiotherapy and surgical excision.

Abstract
Central nervous system involvement by ovarian serous adenocarcinoma is rare. We report a case of a 60-year-old woman that developed brain metastasis as isolated site of relapse 4.5 years after a complete resection and adjuvant chemotherapy for a stage Ic disease. She proceeded to a craniotomy with resection of the lesion and, subsequently, to a whole brain radiotherapy. Nineteen months later, she developed carcinomatous meningitis as isolated site of recurrence. Patient was submitted to intrathecal chemotherapy with methotrexate; however, she died from progressive neurologic involvement disease few weeks later.

Abstract
The adaptive immune system is involved in tumor establishment and aggressiveness. Tumors of the ovaries, an immune-privileged organ, spread via transceolomic routes and rarely to distant organs. This is contrary to tumors of non-immune privileged organs, which often disseminate hematogenously to distant organs. Epigenetics-based immune cell quantification allows direct comparison of the immune status in benign and malignant tissues and in blood. Here, we introduce the "cellular ratio of immune tolerance" (immunoCRIT) as defined by the ratio of regulatory T cells to total T lymphocytes. The immunoCRIT was analyzed on 273 benign tissue samples of colorectal, bronchial, renal and ovarian origin as well as in 808 samples from primary colorectal, bronchial, mammary and ovarian cancers. ImmunoCRIT is strongly increased in all cancerous tissues and gradually augmented strictly dependent on tumor aggressiveness. In peripheral blood of ovarian cancer patients, immunoCRIT incrementally increases from primary diagnosis to disease recurrence, at which distant metastases frequently occur. We postulate that non-pathological immunoCRIT values observed in peripheral blood of immune privileged ovarian tumor patients are sufficient to prevent hematogenous spread at primary diagnosis. Contrarily, non-immune privileged tumors establish high immunoCRIT in an immunological environment equivalent to the bloodstream and thus spread hematogenously to distant organs. In summary, our data suggest that the immunoCRIT is a powerful marker for tumor aggressiveness and disease dissemination.

Chen CW, Torng PL, Chen CL, Chen CA. Clinical features and outcomes of neck lymphatic metastasis in ovarian epithelial carcinoma. World J Surg Oncol 2013; 11:255. [PMID: 24088247 PMCID: PMC3850746 DOI: 10.1186/1477-7819-11-255] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2013] [Accepted: 09/22/2013] [Indexed: 11/25/2022] Open
Abstract
Background Neck lymph node metastasis (NLNM) in epithelial ovarian cancer (EOC) is rare and treated as advanced stage cancer. However, ovarian cancer with lymphatic metastasis may manifest a different clinical course from peritoneal carcinomatosis. Methods The authors retrospectively assessed 20 patients with EOC and pathologically diagnosed as NLNM between January 2001 and December 2010. The patients were divided into two groups according to the time of NLNM identification. Statistical methods included Kaplan-Meier, log-rank, and Cox regression analysis. Results Eleven patients were diagnosed with NLNM at the same time of surgical exploration of EOC (Group A) and nine patients at cancer recurrence 43.3 months after initial surgery (Group B). In Group A, patients with tumors confined to the pelvic cavity had no recurrence or had isolated lymph node recurrence (ILNR), and survived longer than patients with abdominal tumor spreading (P = 0.0007). In Group B, 2 patients showed ILNR. The median survival time after NLNM was 42 months in Group A and 6 months in Group B (P = 0.01). Cox model demonstrated that non-serous histology, brain metastasis, and NLNM identified at cancer recurrence were major predictors for poor overall survival (Hazard ratio [HR] = 18.67, 6.93, and 4.52; P = 0.01, 0.02, and 0.04, respectively). Conclusions A subgroup of EOC patients with NLNM who presented limited pelvic cancer had much better overall survival than patients who had cancer spreading beyond the pelvic cavity or were diagnosed with NLNM at cancer recurrence.

Recurrence patterns after extended treatment with bevacizumab for ovarian, fallopian tube, and primary peritoneal cancers. Gynecol Oncol 2013; 130:295-9. [PMID: 23632207 DOI: 10.1016/j.ygyno.2013.04.055] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2013] [Revised: 04/19/2013] [Accepted: 04/22/2013] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To evaluate patterns of recurrence for ovarian, fallopian tube, and primary peritoneal cancer patients undergoing extended treatment with bevacizumab (BEV). METHODS A retrospective review of patients with primary ovarian, fallopian tube, or peritoneal cancer treated with BEV alone or in combination with other chemotherapy from 2001 to 2011 was performed. Qualified patients were identified by chemotherapy records. Electronic medical records, labs, and imaging reports were reviewed and abstracted. RESULTS Of 108 patients identified, 89 patients met study criteria by having disease progression either during treatment with BEV or after discontinuing BEV without initiating any other treatment. Patients on extended BEV therapy (>12 cycles) were more likely to recur in extra-visceral sites (p=0.04), especially in lymph nodes (p=0.0002), and presented with fewer symptoms at time of recurrence (p=0.02), compared to patients who had received ≤ 12 cycles. CA-125 becomes less reliable for the detection of recurrent disease with extended BEV therapy (p=0.03 for ≤12 cycles vs. p=0.08 for >12 cycles). Radiology was superior to CA-125, symptom, and physical exam, in detecting recurrence with extended BEV therapy (all p<0.0001). CONCLUSIONS Extended treatment with BEV in ovarian, fallopian tube, and peritoneal cancers results in alterations in the patterns of recurrence. Radiologic imaging is more reliable than CA-125, symptoms, or physical exam, in identifying recurrent disease in patients undergoing BEV treatment. As novel targeted therapies continue to be employed, guidelines for gynecologic cancer surveillance must continue to be reexamined.

Abstract
OBJECTIVE Although brain metastases from gynecologic malignancies are rare, such cases have been gradually increasing in number. The aim of the present study was to evaluate the clinicopathologic features and prognostic factors of brain metastases from gynecologic malignancies. METHODS Retrospective analysis of 139 patients with brain metastases from gynecologic malignancies was carried out as a multi-institutional study. The clinicophathological data of the patients were collected from medical records. RESULTS Median survival time of the patients with brain metastases was 12.5 months for the ovarian cancer group, 6.2 months for the corpus cancer group, and 5.0 months for the cervical cancer group; two-year overall survival rates were 19.7%, 6.1%, and 4.8%, respectively. Multivariate analysis revealed ovarian/tubal/peritoneal origin, KPS >70, single brain metastasis, absence of extracranial disease, cranial surgery, cranial radiotherapy, and chemotherapy to be independent favorable prognostic factors associated with overall survival. CONCLUSION It is considered that aggressive multimodal therapy is warranted in the treatment of brain metastases from gynecologic malignancies in carefully selected patients. The present study may provide a platform for the discussion of management strategies in these rare clinical scenarios.

Abstract
BACKGROUND AND PURPOSE Assessment of prognostic factors might influence treatment decisions in patients with brain metastases. Based on large studies, the diagnosis-specific graded prognostic assessment (GPA) score is a useful tool. However, patients with unknown or rare primary tumours are not represented in this model. A pragmatic approach might be use of the first GPA version which is not limited to specific primary tumours. PATIENTS AND METHODS This retrospective analysis examines for the first time whether the GPA is a valid score in patients not eligible for the diagnosis-specific GPA. It includes 71 patients with unknown primary tumour, bladder cancer, ovarian cancer, thyroid cancer or other uncommon primaries. Survival was evaluated in uni- and multivariate tests. RESULTS The GPA significantly predicted survival. Moreover, improved survival was seen in patients treated with surgical resection or radiosurgery (SRS) for brain metastases. The older recursive partitioning analysis (RPA) score was significant in univariate analysis. However, the multivariate model with RPA, GPA and surgery or SRS versus none showed that only GPA and type of treatment were independent predictors of survival. CONCLUSION Ideally, cooperative research efforts would lead to development of diagnosis-specific scores also for patients with rare or unknown primary tumours. In the meantime, a pragmatic approach of using the general GPA score appears reasonable.

Abstract
OBJECTIVE To evaluate the characteristics and outcome of patients with brain metastases from epithelial ovarian carcinoma. METHODS The clinical and pathologic characteristics, treatment and outcome of patients with brain metastases from epithelial ovarian carcinoma were analyzed from eight medical centers in Taiwan under the TGOG (Taiwanese Gynecologic Oncology Group). RESULTS A total of 64 patients were recruited in this study. The incidence of brain metastases from epithelial ovarian carcinoma seemed to be increasing in recent years. The median survival from the diagnosis of brain metastases was 8 months (range: 0-72). Prior cancer relapse before the diagnosis of brain metastases, number of brain metastases and multimodal treatment were related to the duration of survival. CONCLUSIONS The prognosis for patients with brain metastases from epithelial ovarian carcinoma is generally poor. However, clinicians should keep alert to the neurological complaints of ovarian cancer patients and the patients might benefit from aggressive multimodal treatments.

Abstract
This paper will focus on knowledge related to brain metastases from ovarian carcinoma. So far, less than 600 cases were documented in the literature with an incidence among ovarian carcinoma patients ranging from 0.29% to 11.6%. The ovarian carcinoma was usually an advanced-stage epithelial serous carcinoma, and the median interval between diagnosis of ovarian carcinoma and brain metastases was 2 years. Most often, brain metastases, affected the cerebrum, were multiple and part of a disseminated disease. Treatment of brain metastasis has evolved over the years from whole brain radiotherapy (WBRT) only to multimodal therapy including surgical resection or stereotactic radiosurgery followed by WBRT and/or chemotherapy. The median survival after diagnosis of brain metastases was 6 months; nevertheless, a significantly better survival was achieved with multimodal therapy compared to WBRT only. It is suggested that brain imaging studies should be included in the followup of patients after treatment for ovarian carcinoma.
