Primary central nervous system lymphoma: a report of 28 patients / 中华肿瘤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical characteristics, reasonable mode of treatment and prognostic factors in patients with primary central nervous system lymphoma (PCNSL).</p><p><b>METHODS</b>Twenty-eight patients with PCNSL treated from 1989 to 2002 were retrospectively reviewed. The clinical characteristics, results of treatment and prognostic factors were analyzed by SPSS10.0 statistic software.</p><p><b>RESULTS</b>Of 28 patients, 18 men and 10 women with a median age of 52 years. The median survival time was 2 years (range 6 months-6 years). The 5-year survival rate was 21.4%. Nineteen patients had single-locus lesion and 9 multi-locus lesion, 78.6% of the patients were diagnosed as having B-cell origin, its main type being diffuse large cell lymphoma. According to international working formulation (WF), moderate-grade of histopathology was observed in 57.7% (15/28). Cox regression analysis revealed that single- or multi-locus lesion was only independent prognostic factor (P = 0.0417). Combined chemotherapy showed significant efficacy for those patients who had lesion of B-cell origin, high grade or multi-locus lesion, and the efficacy of irregular chemotherapy was better than that of regular chemotherapy.</p><p><b>CONCLUSION</b>Primary central nervous system lymphoma has a special prognostic factor. Chemotherapy plays a very important role in comprehensive treatment, irregular chemotherapy should be adopted as a regular treatment.</p>
