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
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: Clinical datasets for epithelial ovarian cancer brain metastatic patients are usually small in size.
When adequate case numbers are lacking, resulting estimates of regression coefficients may demonstrate bias. One
of the direct approaches to reduce such sparse-data bias is based on penalized estimation. Methods: A re- analysis of
formerly reported hazard ratios in diagnosed patients was performed using penalized Cox regression with a popular
SAS package providing additional software codes for a statistical computational procedure. Results: It was found
that the penalized approach can readily diminish sparse data artefacts and radically reduce the magnitude of estimated
regression coefficients. Conclusions: It was confirmed that classical statistical approaches may exaggerate regression
estimates or distort study interpretations and conclusions. The results support the thesis that penalization via weak
informative priors and data augmentation are the safest approaches to shrink sparse data artefacts frequently occurring
in epidemiological research.

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.

Abstract
BACKGROUND In this report we present the results of the retrospective (survival and classification) analyses of possible prognostic factors prolonging survival in epithelial ovarian cancer brain metastases patients after stereotactic radiotherapy. We focus on a wide range of available predictors to establish survival in patients with a good health status and no more than three lesions. METHODS Two parallel statistical methods in survival analysis were used: classical and Bayesian methods to verify statistical results. To display the predicted and posterior survivals, classification trees were built. RESULTS From the initial set of prognostic factors, only four were established as statistically significant in multivariate regression. They were: survival to metastases to brain after epithelial ovarian cancer diagnosis, number of metastases at diagnosis, central nervous system radiotherapy prior to stereotactic radiotherapy, and interval to stereotactic radiotherapy after metastases diagnosis. CONCLUSIONS When considering evidence-based standards of treatment of patients suffering from epithelial ovarian cancer brain metastases, the established clinical factors are suggested to be prognostic.

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.
