Abstract:
PURPOSE: Peripheral T-cell lymphoma (PTCL) derived from mature T cells forms morphologically diverse group of non-Hodgkin's lymphomas and the clinicopathologic features remain to be debated. In order to elucidate the specific characteristics of PTCL, comparison with a group of diffuse B-cell lymphomas (DBCL) was done. MATERIALS AND METHODS: Between Dec. 1989 and Feb. 1993, clinical data of 67 cases of intermediate or high grade NHL identified as T-cell or B-cell origin by immunophenotyping was reviewed. RESULTS: There were 30 cases of PTCL and 37 cases of DBCL. PTCL had more advanced stage and B symptoms at diagnosis. Frequent sites of extranodal involvement were bone marrow, nasal cavity/paranasal sinus, and skin in PTCL and gastrointestinal tract in DBCL. Based on NCI Working Formulation, 40% of PTCL and 14% of DBCL were high grade. Patients with DBCL had a better 3-year overall survival rate (67% vs 47%), however, there was no difference in complete remission rate and disease-free survival rate between two groups with intensive treatment. A subgroup of PTCL patients who had died earlier was found to have more advanced stage and poor performance status. CONCLUSION: Although patients with PTCL had worse survival in advanced stage, the outcome of patients with PTCL who received intensive treatment was comparable to that of DBCL.
