Objective:To summarize the experiences of the surgical treatment of tumors in the posterior part of the third ventricle and pineal region. Methods: Twenty seven patients with tumors in this region treated microsurgically from 1990 to 2000 were analyzed. The surgical indications, approaches, and operative key points were discussed. The prognostic factors were also analyzed. Results:Tumors were removed totally in 11 patients, removed subtotally in 7 and removed partially in 5. Biopsy and ventriculo peritoneal shunt was performed in 4 patients. Of 17 patients in follow up, 13 patients survived longer than 5 years. Conclusions: Most tumors in the posterior part of the third ventricle and pineal region can be surgically removed.Sufficient specimen obtained in the operation can confirm pathologic property of the tumor,guiding next chemotherapy and radiotherapy.
