- MCL is a rare entity of non-Hodgkin lymphoma, hitherto considered incurable. There is no standard therapy, but the current treatment results do seem to have led to a prolongation of the median survival from 3 to 5 years. Following CHOP-like induction, high-dose radiochemotherapy, and autologous stem cell transplantation (ASCT) chemotherapy has been shown in a controlled trial to be superior in younger patients, but does not, however, lead to long-term freedom from disease. Results of recent prospective but uncontrolled trials of more intensive frontline immunochemotherapy containing cytarabine and rituximab followed by ASCT, however, now for the first time indicate plateaus of the curves of event-free, progression-free and overall survival, suggesting cure, but more studies and longer follow-up is needed. Following relapse, autologous stem-cell transplantation does not seem to be of value, but graft-versus-lymphoma effect has been documented, and allogeneic stem cell transplantation with reduced-intensity conditioning is emerging as the treatment of choice in this setting.

- Celecoxib, an inhibitor of cyclooxygenase-2, is a promising novel antitumor agent with pleitropic mechanisms of action. Whereas this drug induces growth arrest and apoptosis of B-lymphoma cells, its effect against aggressive T-cell neoplasms remains to be studied. We therefore evaluated Celecoxib therapy of immunocompetent mice transplanted with lymphoblastic T-cell lymphomas. Oral Celecoxib in clinically relevant and non-toxic doses did not affect the degree of hypersplenism or the number of viable lymphoma cells. The clinical deterioration of Celecoxib-treated mice was not different from untreated controls. The impact of adding Celecoxib (60 mg/kg) to cyclophosphamide (200 mg/kg x 1, i.p.) was assessed but showed no benefit compared to cyclophosphamide alone. Thus, Celecoxib lacks effect against lymphoblastic T-cell lymphoma in mice.

- The purpose of this phase II randomized trial was to evaluate the effect and safety of interferon-alpha2a (IFN) in combination with extended dosing rituximab in patients with symptomatic, advanced indolent lymphoma responding to a standard single course of rituximab. Totally 123 patients were treated with rituximab 375 mg/m2 once weekly for 4 weeks leading to 14 complete response (CR; 11%), 56 partial response (PR; 46%), and 13 minor responses (MR; 11%). Patients achieving either PR or MR were randomized to four more infusions of rituximab alone (n = 36) or in combination with five weeks of IFN (n = 33), with an overall response rate (CR + PR) of 78% and 94%, respectively. Significantly more patients in the combination arm improved their response from PR/MR to CR (P < 0.05) and more maintained their responses for > or = 24 months (72% versus 50%), respectively. Overall, 26 out of the 52 patients who achieved CR underwent minimal residual disease (MRD) evaluation. Totally 17 of these (65%) achieved MRD negativity, 14 of whom remain in CR after 4.8 years' follow-up. The addition of IFN to rituximab was generally safe, but reversible thrombocytopenia and neutropenia were noted in one and six patients, respectively, requiring a reduction in the IFN dose. Extended rituximab is effective and well tolerated and combination with IFN seems to improve both the quality and duration of the responses, providing the opportunity to achieve long-term molecular CRs and prolonged failure-free survival without chemotherapy.

CD40 expression identifies a prognostically favourable subgroup of diffuse large B-cell lymphoma

Tidskriftsartikel (refereegranskat)abstract
- In order to confirm our earlier findings of the prognostic effects of CD23 and CD40 expression in diffuse large B-cell lymphoma (DLBCL), possibly due to association with the germinal center (GC) phenotype and/or an increased autologous tumour response, tumour specimens from 125 patients with de novo DLBCL were investigated for immunohistochemical expression of CD23, CD40, BCL6, CD10, MUM1, CD4 and CD8. CD40 was positive in 64% and was associated with improved overall survival (p = 0.03). A GC phenotype was present in 47%, and was also associated with a better overall survival (p = 0.006) but did not correlate with CD40-expression. There was no correlation between amount of tumour infiltrating T-cells and CD40-positivity. CD23 was positive in 10% and expression did not correlate with prognosis. In conclusion, the prognostic effect of CD40 expression was confirmed, but did not correlate with GC-phenotype or T-cell infiltration.
