Presenting features, natural history, and prognostic factors in localized non-Hodgkin's lymphomas: analysis of 117 cases from a single institution.
Clinical features and prognostic factors were analyzed in a series of 117 patients with localized non-Hodgkin's lymphoma (stage I-II). Median age of the patients was 53 years and 52% were men; 22% had a lymphoma of low-grade histology and one-third presented with extranodal involvement. Eighty percent of the patients achieved a complete response (CR); stage of disease and histology were revealed as the most important factors for response. When analysis was restricted to intermediate/high-grade cases, stage showed a predictive value for response. With a median follow-up of 4.5 years, median overall survival was 12.0 years, with 73% and 62.5% of patients being alive at 5 and 10 years, respectively. Main initial parameters significantly related to a shorter survival were intermediate/high-grade histology, stage II, poor performance status, bulky disease, high serum LDH levels, increased ESR, and advanced International Index. In the multivariate analysis, stage, histology and performance status (PS) were statistically significant. Among intermediate/high-grade lymphoma patients, stage and PS provided prognostic value for survival. Twenty-six patients relapsed after CR; median survival after relapse was 2.7 years. Stage (I vs II) was the only predictive variable for relapse in both the whole series and the intermediate/high-grade subset.
