EFFECT OF FOLLICULARITY ON AUTOLOGOUS TRANSPLANTATION FOR LARGE-CELL NON-HODGKINS-LYMPHOMA

Purpose: This study evaluated the outcomes of patients who received hi gh-dose chemotherapy (HDC) and autologous hematopoietic stem-cell tran splantation (ASCT) for large-cell non-Hodgkin's lymphoma (NHL) and the effect of ct follicular versus a diffuse histology. Patients and Meth ods: The prognostic factors in 289 patients who underwent HDC and ASCT for large-cell NHL between May 1983 and December 1996 were analyzed.R esults: With a median follow-up duration of 24 months for surviving pa tients (range, 3 to 131 months), 112 of 289 (39%) were alive and 82 of 289 (28%) were failure-free. In a multivariate analysis, the factors associated with a poorer failure-free survival (FFS) included a lactic dehydrogenase (LDH) level greater than normal (P < .0001), three or m ore prior chemotherapy regimens received (P < .01), a mass greater tha n or equal to 10 cm at transplant (P < .01), and diffuse histology at the time of transplant (P = .026). Patients who received HDC and ASCT for large-cell NHL in the good-prognosis category (normal LDH, < three prior chemotherapy regimens, no large mass, and not chemotherapy-resi stant) had a 5-year survival rate of 45%. Within the good-prognosis gr oup, patients with diffuse large-cell NHL had a 5-year survival rate o f 42% compared with 58% for patients with follicular large-cell (FLC) lymphoma (P = .05). Conclusion: Good-prognosis patients with FLC histo logy who receive HDC and ASCT have an improved survival compared with good-prognosis patients with a diffuse large-cell histology.
