Abstract

Background: Treatment of primary central nervous system lymphoma (PCNSL) in Chinese individuals has rarely been reported. Therefore, this article presents our experience in managing PCNSL with radiotherapy. Methods: A thorough review was made of the medical records of 13 patients diagnosed with PCNSL at Kaohsiung Chang Gung Memorial Hospital from 1988 through 1997. The clinical characteristics, treatment modalities, and results were analyzed as well. Results: Thirteen patients diagnosed with PCNSL were identified, of which 10 cases originated in the brain whereas three were of spinal origin. Seven of the patients were man and six were women, with a mean age of 54.9±13.1 years (range 29 to 74 years). Diffuse large cell lymphoma (11 cases) was the most common histology. Limb weakness (11 cases) and headache (7 cases) were the most common complaints at presentation. Nine patients received radiation therapy alone and four patients received radiation therapy plus chemotherapy after surgical resection or biopsy. Follow-up computed tomography (CT) scans 3 to 4 months after the completion of radiotherapy revealed that nine patients (69%) had a complete response and four (31%) had a partial response. Local recurrence occurred in five patients (56%) treated with radiation therapy alone and in one patient (25%) treated with combined modalities. The overall actuarial survival rate was 54% at 2 years and 27% at 5 years. Conclusion: Results in this study indicate that the initial response to radiotherapy is satisfactory. However, a local relapse frequently occurs. Future considerations should focus on new modes of treatment, such as three- dimensional conformal radiation therapy for dose escalation or combination of chemotherapy and radiotherapy.
