title: Thalamic tumors in children.
abstract: Thalamic tumors (TT) merit individual analysis and must not be confused with tumors that, while involving the entire thalamus have a different origin. We analyzed 26 patients who fulfilled our criteria of having "strictly" TT. We examined incidence, clinical features, histology, response to treatment (mainly surgery), recurrence rate, mortality and prognosis. We considered that histology and surgical treatment were the most important items related to prognosis. Low-grade tumors (LGT) had a good prognosis, while anaplastic tumors (AT) had a discouraging one; nevertheless both must be operated on. We believe that total removal of LGT is curative and total removal of AT, even if it is not curative, can extend survival by some months. Radiotherapy and chemotherapy seemed to be of little value in our series of TT.
