Aims And Background:
Primary CNS lymphomas are uncommon tumors in immunocompetent patients. We describe the radiological features that should orient towards performing a biopsy and analyze the results in our series of patients.
Methods:
We reviewed 22 immunocompetent patients with primary central nervous system lymphoma admitted in our Institute between 1977 and 1997. The follow-up period ranged from 2 months (patient deceased) to 69 months. Fourteen patients underwent surgical removal of the tumor and the remainder a biopsy. All patients received radiotherapy and 8 patients radiotherapy plus chemotherapy.
Results:
Two of the 14 patients treated by surgical removal of the tumor died. There was no mortality related to biopsy procedures. Patients treated with radiotherapy had 1-year, 2-year and 5-year survival rates of 66%, 41.6% and 16.6%, compared to 87.5%, 62.5% and 50%, respectively, for patients who received radiotherapy and chemotherapy.
Conclusions:
At present, there is no definite treatment for these highly malignant brain tumors. The most favorable results seem related to biopsy followed by radiotherapy plus chemotherapy versus surgical removal, which is related to a high risk of severe postoperative deficit for both the deep location and infiltrating nature of these lesions.
