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.
