One single dose of rituximab added to a standard regimen of CHOP in primary treatment of follicular lymphoma appears to result in a high clearance rate from circulating bcl-2/IgH positive cells: Is the end of molecular monitoring near?

Abstract

Accurate monitoring of the t(14;18) translocation is regarded as highly desirable in patients with follicular lymphoma (FL) as absence of bcl-2/IgH positive cells has been correlated with a reduced risk of recurrence and, more recently, pre-treatment t(14;18) load with response to rituximab (R; Blood 2004;103:4416-23). With the arrival of R clinical and molecular remission rates for various lymphoma entities improved significantly, creating the need to carefully review and reassess the role of PCR negativity for clinical outcome, specifically when considering the prolonged presence of the drug as compared to chemotherapy. To determine the rate of molecular clearance achieved by the addition of different doses of R 16 newly diagnosed, t(14;18) positive patients with FL (Ann Arbor stages III/IV) were investigated before, during and after primary chemotherapy with six cycles of CHOP combined with varying (1, 3 or 6) cycle numbers of R (varR1-, varR3- or varR6-CHOP, respectively) regarding molecular remission status. For this purpose classic nested PCR as well as a newly established RQ-PCR employing juxtaposed hybridisation probes were employed to assess molecular remission prior, during and post therapy. Interestingly, administeri...Continue Reading

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.
