Abstract Little is known about the expression of bcl-2 protein in intermediate and high grade non-Hodgkin's lymphoma (NHL) and its clinical and prognostic significance. We performed immunohistochemical analysis of bcl-2 expression in tumoral tissue sections of 348 patients with high or intermediate grade NHL. These patients were uniformly treated with adriamycin, cyclophosphamide, vindesine, bleomycin, and prednisone (ACVBP) in the induction phase of the LNH87 protocol. Fifty eight cases were excluded due to inadequate staining. Of the 290 remaining patients, 131 (45%) disclosed homogeneous positivity (high bcl-2 expression) in virtually all tumor cells, whereas 65 (23%) were negative and 94 (32%) exhibited intermediate staining. High bcl-2 expression was more frequent in B-cell NHL (109 of 214, 51%) than in T- cell NHL (6 of 35, 17%) (P = .0004), and was heterogeneously distributed among the different histological subtypes. Further analysis was performed on the 151 patients with diffuse large B-cell lymphoma (centroblastic and immunoblastic) to assess the clinical significance and potential prognostic value of bcl-2 expression in the most frequent and homogeneous immunohistological subgroup. High bcl-2 expression, found in 44% of these patients (67 of 151), was more frequently associated with III-IV stage disease (P = .002). Reduced disease-free survival (DFS) (P < .01) and overall survival (P < .05) were demonstrated in the patients with high bcl-2 expression. Indeed, the 3-year estimates of DFS and overall survival were 60% and 61%, respectively (high bcl-2 expression) versus 82% and 78%, respectively (negative/intermediate bcl-2 expression). A multivariate regression analysis confirmed the independent effect of bcl-2 protein expression on DFS. Thus bcl-2 protein expression, as demonstrated in routinely paraffin-embedded tissue, appears to be predictive of poor DFS, in agreement with the role of bcl-2 in chemotherapy-induced apoptosis. It might be considered as a new independent biologic prognostic parameter, which, especially in diffuse large B-cell NHL, could aid in the identification of patient risk groups.

Abstract This study aimed to evaluate the role of RIC allo-SCT for relapsed or refractory non-Hodgkin’s lymphoma (NHL). We report here our experience in 25 consecutive patients transplanted in a single center for high grade (n=17) or follicular NHL (FL; n=8). In the high grade NHL group, median age was 46 (range, 24–63) years, and all 17 patients received 2 or more previous chemotherapy regimens prior to RIC allo-SCT. In addition, 12 patients (71%) had failed autologous SCT and 6 patients (35%) had chemoresistant disease at time of allo-SCT. Among the 8 patients transplanted for a heavily pretreated follicular NHL (FL), median age was 52 (range, 34–59) years and median number of prior lines of therapy was 3 (range, 2–5), with 3 patients (38%) having chemoresistant diseases and 4 patients (50%) relapsing after autologous SCT. Among the 17 patients with aggressive high grade NHL, we compared the outcome of T-cell and B-cell aggressive NHL. With a median follow-up of 15.4 (range, 3.4-65.2) months, the cumulative incidence of non-relapse mortality was 6%, (95%CI, 0.3%-31%) and the Kaplan-Meier estimate of progression-free survival (PFS) was significantly higher in the T-cell as compared to the B-cell group (P= 0.03; 100% vs. 40% at 3 years). In the FL group, the cumulative incidence of non-relapse mortality was 25% (95%CI, 3%–65%). Six patients (75%) showed objective disease response with complete remission (CR) occurring concomitantly to graft-versus-host disease, including one CR after donor lymphocytes infusion. With a median follow-up of 19 (range, 7–85) months, 6 patients from the FL group are still alive of whom 5 in CR. We conclude that a potent graft-vs.-lymphoma (GVL) may be achieved in FL patients, even those with chemoresistant disease or who have relapsed after autologous SCT. In the high grade NHL group, strategies aiming to enhance the GVL effect (Rituximab-based RIC and/or Rituximab maintenance therapy) in the B cell subtype are still needed. However, RIC allo-SCT is a feasible and promising strategy for aggressive NHL, with particularly low toxicity, and T-cell aggressive NHL benefiting most from a potent GVL effect, likely overcoming the poor prognosis usually associated with this phenotype.

Working Formulation

The Bcl-2 protein is capable of preventing apoptosis, and in vitro evidence suggests a role in drug resistance. It is expressed and the gene is rearranged in a proportion of cases of large-cell non-Hodgkin's lymphoma (NHL), but the clinical significance of these findings is controversial. The purpose of this study was to determine the influence of both Bcl-2 expression and major breakpoint region (MBR) bcl-2 rearrangement in a large cohort of prospectively accrued patients with intermediate-grade B-cell NHL treated in a standardized manner. All patients with Working Formulation F, G, or H NHL treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy in British National Lymphoma investigation studies between July 1974 and April 1992 were considered for this study if the appropriate paraffin blocks were available. Paraffin sections from the diagnostic specimen were analyzed for evidence of MBR rearrangement using a polymerase chain reaction-based method, and for Bcl-2 expression using immunohistochemistry. Failure to achieve complete remission (CR), relapse, death from NHL, and deaths from all causes were used as end points to measure CR rate, actuarial relapse rate, actuarial survival from NHL, and actuarial overall survival. One hundred sixty-one suitable patients were identified and tested for the bcl-2 MBR translocation, with 27 (17%) found to be positive; 153 of these patients were tested with immunocytochemistry, and 84 (55%) showed evidence of Bcl-2 expression. For patients who achieved CR from the initial treatment, the relapse rate was significantly higher in those with Bcl-2 expression than in those without. In addition, multivariate analysis identified Bcl-2 expression as the only factor significantly related to relapse rate in the subjects measured. The cause-specific survival for NHL in the series as a whole was significantly lower in patients with Bcl-2 expression than in those without. MBR status had no significant influence on any of the outcome measures, but the number of MBR-positive patients was relatively small, and larger studies are required. In conclusion, in Working Formulation F, G, and H NHL of B-cell type, expression of Bcl-2 protein predicted independently for relapse.
