title: Is Neurosurgery With Adjuvant Radiotherapy an Effective Treatment Modality in Isolated Brain Involvement From Endometrial Cancer?: From Case Report to Analysis.
abstract: The aim of this study was to evaluate the treatment options and post-brain involvement survival (PBIS) of patients with isolated brain involvement from endometrial cancer (EC).
  
  
  
  The literature electronic search was conducted from 1972 to May 2016 to identify articles about isolated (without extracranial metastases) brain involvement from EC at recurrence and the initial diagnosis. Forty-eight articles were found. After comprehensive evaluation of case series and case reports, the study included 49 cases.
  
  
  
  The median age of the patients at initial diagnosis was 57 years (range, 40-77 years). Poor differentiation was determined in 36 (73.5%) patients. Thirty-five (71.4%) patients had a single brain lesion. Lesion was found in the supratentorial part of the brain in 33 (67.3%) patients. Median PBIS for all cohorts was 13 months (range, 0.25-118 months) with 2-year PBIS of 52% and 5-year PBIS of 37%. Age, tumor type, grade, disease-free interval, diagnosis time of brain lesion, localization, and number of brain lesion were not predictive of PBIS. Two-year PBIS was 77% in patients who underwent surgical resection and radiotherapy, whereas it was 19% in the surgical resection-only group, and 20% in the primary radiotherapy-only group (Ps = 0.003 and 0.001, respectively). Chemotherapy was not associated with improved PBIS.
  
  
  
  Although neuroinvasion from EC appears mostly with a disseminated disease, there is a considerable amount of patients with isolated brain involvement who would have a higher chance of curability. Surgery with radiotherapy is the rational current management option, and this improves the survival for isolated brain involvement from EC.
