Stereotactic radiosurgery for brain metastases arising from gynecological malignancies: A retrospective treatment outcome analysis. J Clin Neurosci 2024; 121:89-96. [PMID: 38377883 DOI: 10.1016/j.jocn.2024.02.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 02/08/2024] [Accepted: 02/14/2024] [Indexed: 02/22/2024]
Abstract
BACKGROUND This retrospective study aims to assess the efficacy of stereotactic radiosurgery (SRS) in the treatment of brain metastases (BM) originating from gynecological cancers. It focuses on local control (LC), distant tumor control (DTC), and overall survival (OS). METHODS The analysis comprised 18 individuals with gynecological-origin BM treated with SRS at the Hadassah Medical Center from 2004 to 2021. Statistical analyses evaluate factors impacting LC, DTC, and OS. RESULTS A total of 36 BM of gynecological origin underwent SRS. The median age at the first SRS treatment was 60 years, with a median time of 24.5 months from the primary malignancy diagnosis to BM detection. The 12-month LC rate per patient was 84.6 %, and 5.6 % per BM. Only two instances of local recurrence were observed. The DTC at 12 months was 75 %, with a 29 % overall. Non-significant trends indicating a correlation with distant brain failure with increased cumulative volume and the occurrence of craniotomy before SRS. The median OS of the cohort was 16.5 months from SRS treatment. The 6, 12, 18, and 24-month survival rates were 77.8 %, 66.7 %, 50 %, and 22.2 % respectively. Higher number of BM was associated with lower OS (p = 0.046). On multivariate analysis, age was a significant factor for OS (p = 0.03), demonstrating that older age was associated with a more favorable prognosis. CONCLUSION This study supports SRS effectiveness for treating BM from gynecological cancers and suggests similar outcomes to more common malignancies.

Abstract
OBJECTIVE This study aims to evaluate the efficacy of stereotactic radiosurgery (SRS) in improving health outcomes of patients with gynecologic brain metastases. METHODS Patients with gynecologic metastases treated with SRS from 2008 to 2020 were retrospectively reviewed. The median age at SRS was 63 years old (cervical 45.5, endometrial 65.5, ovarian 61). The median number of tumors was 3 (range 1-27), and cumulative tumor volume was 2.33 cc (range 0.03-45.63). Median margin dose prescribed was 16 Gy (range 14 Gy - 20 Gy). The median 12 Gy volume was 7.30 cc (range 0.21-74.14 cc). Outcome variables included overall survival (OS) after SRS, local tumor control (LTC), distant tumor control, and adverse radiation effect (ARE). RESULTS Fifty patients (4 cervical, 25 endometrial, and 21 ovarian cancer) were identified. The OS at 6 and 12 months after SRS was 48%, and 44%, respectively. Eight patients (16%) died from CNS disease progression. The number of brain metastases (p = 0.011) and the Karnofsky Performance Scale (KPS) ≥ 70 (p = 0.020) were significant predictors of OS. LTC rate at 6 and 12 months were 92%, and 87%, respectively. Margin dose ≥16Gy correlated with significantly better local tumor control (p = 0.0001) without increased risk of ARE (p = 0.055). The risk of developing new metastases at 6 and 12 months were 12% and 24% respectively. SRS-induced ARE events occurred in 7 patients. CONCLUSION Intracranial metastases from gynecologic malignancy can be effectively treated using SRS with low risk of neurotoxicity. Margin dose ≥16Gy can provide significantly better tumor control. Repeat SRS can be utilized to treat new metastases while avoiding the potential cognitive symptoms associated with WBRT.

Curr Probl Cancer 2023; 47:100918. [PMID: 36502584 DOI: 10.1016/j.currproblcancer.2022.100918] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Revised: 11/08/2022] [Accepted: 11/08/2022] [Indexed: 12/02/2022]
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
OBJECTIVE Brain metastasis is rare in ovarian cancer patients. The results of Gamma Knife radiosurgery (GKRS) for the treatment of patients with brain metastases from ovarian cancer were retrospectively analyzed to derive the efficacy and prognostic factors for survival and local tumor control. Further histopathological analysis was also performed. METHODS The authors retrospectively reviewed the medical records of 118 patients with 566 tumors who had undergone GKRS at the 10 GKRS institutions in Japan. RESULTS After the initial GKRS, the median overall survival time was 18.1 months. Multivariate analysis showed that uncontrolled primary cancer (p = 0.003) and multiple intracranial metastases (p = 0.034) were significant unfavorable factors. Ten patients died of uncontrolled brain metastases at a median of 17.1 months. The 6-, 12-, and 24-month neurological death rates were 3.2%, 4.6%, and 11.9%, respectively. The 6-, 12-, and 24-month neurological deterioration rates were 7.2%, 13.5%, and 31.4%, respectively. The 6-, 12-, and 24-month distant brain control failure rates were 20.6%, 40.2%, and 42.3%, respectively. Median tumor volume was 1.6 cm3 and marginal dose was 20 Gy. The 6-, 12-, and 24-month local tumor control rates were 97.6%, 95.2%, and 88.0%, respectively. Peritumoral edema (p = 0.043), more than 7-cm3 volume (p = 0.021), and prescription dose less than 18 Gy (p = 0.014) were factors that were significantly correlated in local tumor control failure. Eight patients had symptomatic radiation injury. The 6-, 12-, and 24-month GKRS-related complication rates were 3.3%, 7.8%, and 12.2%, respectively. Primary ovarian cancer was histopathologically diagnosed for 313 tumors in 69 patients. Serous adenocarcinoma was found in 37 patients and other types in 32 patients. Median survival times were 32.3 months for the serous type and 17.4 months for other types after initial GKRS. Patients with serous-type tumors survived significantly longer than patients with other types (p = 0.039). The 6-, 12-, and 24-month local tumor control rates were 100%, 98.8%, and 98.8%, respectively. Serous-type tumors were a significantly good prognosis factor for local tumor control after GKRS (p = 0.005). CONCLUSIONS This study established a relationship between the efficacy of GKRS treatment for brain metastases and the histological type of primary ovarian cancer. GKRS for ovarian cancer brain metastasis can provide satisfactory survival and local control, especially in cases of serous adenocarcinoma.

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
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
Objective: Gamma Knife® (GK) (Elekta Instruments, Stockholm, Sweden) radiosurgery is well established for treatment of brain metastases. There are limited data on patients treated with GK from gynecological cancers. The authors sought to determine the effectiveness of the GK in patients with brain metastases from gynecological cancers. Methods: An IRB-approved database was queried for patients with gynecologic cancers treated with GK between June 1996 and May 2016. Imaging studies were reviewed post-SRS (stereotactic radiosurgery) to evaluate local control (LC) and distant brain control (DC). Overall survival (OS), local control, and distant brain control were calculated using the Kaplan-Meier (KM) method and log-rank test. Results: Thirty-three patients underwent SRS for 73 separate cranial lesions. The median age was 58.5 years, and 17 (52%) also had extracranial metastases. Ten (30%) patients had previously received whole brain radiotherapy (WBRT), and 11 (33%) underwent concurrent WBRT. The median tumor volume was 0.96 cm3. Median radiographic follow-up was 11 months. At the time of treatment, 39% of patients were categorized as recursive partitioning analysis (RPA) Class I, 55% as RPA Class II, and 6% as RPA Class III. The local failure rate was 8%. Five patients (15%) developed new brain lesions outside the radiation field with a median progression-free survival (PFS) of seven (range: 3-9) months. Median OS was 15 months from GK treatment. One-year OS was 72.9% from GK treatment. Primary cancer histology was a significant predictor of OS, favoring ovarian and endometrial cancer (p = 0.03). Conclusions: Gamma Knife stereotactic radiosurgery for gynecologic brain metastases leads to excellent control rates of treated lesions. Primary histology may have a significant impact on OS following GK, with improved survival seen with ovarian and cervical cancer following Gamma Knife radiosurgery (p = 0.03).

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
Objective Brain metastases in gynecologic cancer (ovarian, endometrial, and cervical cancer) patients are rare, and the efficacy of Gamma Knife Radiosurgery (GKRS) to treat these had not been evaluated. We assessed the efficacy of GKRS and prognostic factors for tumor control and survival in brain metastasis from gynecologic cancers. Methods This retrospective study was approved by the institutional review board. From May 1995 to October 2012, 26 women (mean age 51.3 years, range 27–70 years) with metastatic brain tumors from gynecologic cancer were treated with GKRS. We reviewed their outcomes, radiological responses, and clinical status. Results In total 24 patients (59 lesions) were available for follow-up imaging. The median follow-up time was 9 months. The mean treated tumor volume at the time of GKRS was 8185 mm3 (range 10–19500 mm3), and the median dose delivered to the tumor margin was 25 Gy (range, 10–30 Gy). A local tumor control rate was 89.8% (53 of 59 tumors). The median overall survival was 9.5 months after GKRS (range, 1–102 months). Age-associated multivariate analysis indicated that the Karnofsky performance status (KPS), the recursive partitioning analysis (RPA) classification, and the number of treated lesions were significant prognostic factors for overall survival (HR=0.162, p=0.008, HR=0.107, p=0.038, and HR=2.897, p=0.045, respectively). Conclusion GKRS is safe and effective for the management of brain metastasis from gynecologic cancers. The clinical status of the patient is important in determining the overall survival time.

Abstract
Gynecologic malignancies represent some of the commonest causes of cancer in the female population. Despite their overall high prevalence, gynecologic malignancies have seldom been reported to metastasize to the brain. The incidence of gynecologic cancers spreading to the brain has been rising, and the optimal management of these patients is not well defined. A retrospective analysis of patients treated over the past ten years with gamma knife radiosurgery (GKRS) for metastatic gynecologic cancer to the brain was performed. Radiographic treatment response, tumor control, metastatic disease progression and survival data were analyzed. Eight patients with ovarian cancer, six patients with endometrial cancer and two separates who carried a diagnosis of cervical cancer or leiomyosarcoma harbored metastatic disease to the brain that was treated with GKRS. The median dose to the tumor margin was 20 Gy (range 10-22 Gy), and the median maximum radiosurgical dose was 31 Gy (range 16-52.9 Gy). Tumor control was achieved in all patients who had follow up imaging studies. Patients with ovarian cancer had prolonged median survival following GKRS compared to patients with endometrial cancer (22.3 vs 8.3 months, p = 0.02). The patient with cervical cancer survived 8 months following her GKRS in the setting of metastatic brain tumor progression, whereas the patient with leiomyosarcoma passed away within several weeks of treatment secondary to disseminated extracranial primary disease. GKRS is a safe and effective means of achieving intracranial tumor control for patients with gynecologic cancer that has spread to the brain.
