Abstract

Objective: To summarize the clinical features and treatment outcomes of peripheral T-cell lymphoma, unspecified (PTCL-US). Methods: The medical records of 78 patients with PTCL-US classified according to the revised European and American lymphoma (REAL) or WHO criteria, 58 males and 20 females, aged 39 (9 - 75), 46 of them (59%) being at the stages III/VI and 40 cases (51.2%) with extranodal involvement), treated from Jan 1994 to Dec 2004 in the Cancer Hospital/ Institute, Chinese Academy of Medical Sciences, were retrospectively analyzed. The patients were followed up for 58 months. Results: Thirty patients (38%) were with high level lactate dehydrogenase (LDH). 34 cases (43.7%) were treated with chemoradiotherapy, and 43 (55%) with chemotherapy alone. After the first line treatment the complete recovery (CR) rate and partial recovery (PR) rate were 55.1% (43/78) and 25.6% (20/78) respectively. 15 cases (19.2%) showed progressive disease (PD) or stable disease (SD). Achieving CR or PR after first-line treatment, 13 cases received autologous peripheral blood stem cell transplantation (APBSCT). The 5-year overall survival rate (OS) and 5-year progressive-free survival rate (PFS) were 41.4% and 33.8% respectively. The 5-year OS of the CR, PR, and PD/SD groups were 65.1%, 21.9%, and 0% respectively. The 5-year OS for the patients treated with first-line APBSCT was 61.5%, not significantly different from that of the patients treated with conventional dose therapy alone (52.3%, P = 0.894). Univariate analysis showed that the factors associated with a worse OS included stage III/IV (P = 0.001), high LDH (P = 0.0001), behavior state score ≥2 (P = 0.001), and bone marrow involvement (P = 0.011). Multivariate analysis showed that LDH level was an independent factor predictive of survival (P = 0.001). International prognostic index and prognostic index for peripheral T-cell lymphoma both predicted the overall survival. Conclusion: A rare lymphoma with aggressive presentation, PTCL-US responds poorly to conventional treatment. The prognosis of the cases with high risk is bad. APBSCT is safe and feasible when CR or PR is achieved after first line treatment.
