Direct comparison of peripheral T-cell lymphomas with their B-cell counterpart.

The aim of this study was to determine the effect of immunophenotype on the clinical characteristics and prognosis of 144 adult Chinese patients with non-Hodgkin's lymphomas. Those entities with well-recognised immunophenotype and clinical characteristics were excluded. Significantly more patients with T-cell lymphomas had B symptoms (52 vs. 30%, p = 0.05) and fewer had bulky disease (7 vs. 25%, p = 0.04). Extranodal involvements of liver, spleen, marrow, nasal region and skin were significantly more common in T-cell lymphomas. On the other hand, gastro-intestinal involvement was more commonly seen in B-cell tumours. Induction chemotherapy of comparable intensity was used in treating these patients. The immunophenotype did not appear to affect significantly their prognosis.
