    Background: Pineal region metastases are rare but often cause severe neurologic deficits. Surgical resection and chemoradiotherapy can provide therapeutic benefit. We investigated the literature to analyze clinical characteristics, management strategies, and survival of adult patients with pineal region metastases. Methods: PubMed, Embase, Scopus, and Cochrane were searched following the PRISMA guidelines, including studies reporting clinical outcomes of patients with pineal region metastases. Clinical presentation, management, and survival were reviewed. Results: We included 31 studies comprising 47 patients. Lung cancer (29.8%) and carcinomas of unknown origin (14.9%) were the most frequent primary tumors. In 48.9% of patients, symptomatic pineal metastases preceded primary tumor diagnosis. Headache (67.4%) and confusion (46.5%) were the most common symptoms. Parinaud syndrome (46.5%) and hydrocephalus (87.2%) were noted. Biopsy (65.9%) was preferred over resection (34.1%), and shunting strategies used were endoscopic third ventriculostomy (43.9%) and ventriculoperitoneal (26.8%). Eleven patients (32.3%) received adjuvant chemotherapy and 32 (68%) received radiotherapy. Posttreatment improvement in symptoms (56.6%) and hydrocephalus (80.5%) were noted. In patients who received adjuvant chemotherapy/radiotherapy, significant improvement in posttreatment performance status occurred with both biopsy (P < 0.001) and resection (P = 0.007). No survival differences were reported between surgery and biopsy (P = 0.912) or between complete and partial resection (P = 0.220). Overall survival was neither influenced by surgical approach (P = 0.157) nor by shunting strategy (P = 0.822). Mean follow-up was 8 months and median overall survival 3 months. Only 2 cases (4.8%) of pineal metastasis showed recurrence. Conclusions: Pineal region metastases carry significant morbidity. Biopsy or surgical resection, combined with adjuvant chemotherapy/radiotherapy and/or shunting, may significantly improve performance status.
