Clinical Trial Summary

the study aims to detect the benefit of maintenance tamoxifen after achieving CR with conventional immuno-chemotherapy and/or radiotherapy in patients with DLDCL

Description:

Diffuse large B-cell lymphoma (DLBCL) is the most common form of aggressive non-Hodgkin lymphoma. The standard immuno-chemotherapy (R-CHOP) markedly improves the prognosis of DLBCL, but up to 40% of patients still experience relapse or incomplete remission . So, there is a need for new targeted therapy for such malignancy. Recent studies identified a potential novel target in DLBCL, the ESR2 gene, which codes for the estrogen receptor beta (ERβ) protein, a receptor that can be targeted with selective ER modulators (SERMs) such as tamoxifen. Recent data shows that exposure of DLBCL cell lines to tamoxifen (either alone or in combination with CHOP chemotherapy) results in apoptosis and growth inhibition in vitro and in vivo. these data suggest the potential importance of ERβ in the pathogenesis of DLBCL as well as a potential role for tamoxifen in the treatment of DLBCL.50-100 patients with newly diagnosed DLBCL will be treated with standard immuno-chemotherapy according to disease stage with detection of ERB and ERA on the tissue samples using IHC. After the end of chemotherapy treatment patients who achieve CR will be randomized to either receive tamoxifen maintenance (20 mg daily) versus follow up to evaluate possible tamoxifen effect on disease recurrence, DFS and OS. PT who achieve CR after 2nd line chemotherapy versus post BMT will also be recruited.
