Prognostic factors of peripheral T-cell lymphoma (PTL): statistical analysis on 30 patients.
Peripheral T-cell lymphoma (PTL) is a distinctive clinical entity, albeit it comprises several diseases with histologically heterogeneous diagnoses. We studied prognostic factors on 30 patients diagnosed and treated at Shikoku Cancer Center Hospital. Clinical findings and laboratory data were evaluated by statistical analysis to investigate the important factors influencing survival duration. Variables influencing survival were stage, leukemic change, bone marrow infiltration (BMI), anti-human T-lymphocyte virus-type I antibody, white blood cell count, and lactate dehydrogenase (LDH). Multivariate analysis revealed high level of LDH and positive BMI as the important factors for short survival. Histological classifications of the Working Formulation and the T-lymphoma classification by Suchi et al. were also evaluated whether these were related with prognosis. Our data revealed that there was no significant relationship between histological subtype and survival duration. The study of prognostic factors provides valuable aids for us to understand the clinical characteristics of PTL patients with various backgrounds.
