Analysis of Molecular Markers of Drug Resistance in Tumor Biopsies From Previously Untreated Aggressive Non-Hodgkin's Lymphoma
An observational study of Non-Hodgkin Lymphoma, run by National Cancer Institute (NCI) at 1 site in United States.
Trial summary
Although the cause(s) of clinical drug resistance in non-Hodgkin's lymphomas (NHL) are unknown, in vitro studies suggest that abnormalities of the cell cycle and mechanisms of apoptosis may play an important role. Read more about this study

About this study
Although the cause(s) of clinical drug resistance in non-Hodgkin's lymphomas (NHL) are unknown, in vitro studies suggest that abnormalities of the cell cycle and mechanisms of apoptosis may play an important role. Clinical studies have now shown that p53, bcl-2 and tumor proliferation all have significant effects on clinical drug resistance. To further investigate the role of genes that control the cell cycle and apoptosis, we wish to correlate the expression of multiple molecular targets [including but not restricted to bcl-2, BAX, bcl-6, MIB-1, p53, p21, p27, p16, cyclin D(1), cyclin A, cyclin E, mdm-2, cpp 32, mcl-1, EBER-1, ALK, and a panel of B, T and other cell lineage markers], involving these pathways, with clinical outcome following treatment with combination chemotherapy. All clinical data and tissue samples for this study will come from patients who have been previously enrolled on two protocols for the initial treatment of aggressive lymphomas. No new patients will be enrolled for this study.

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00026910, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2008; AzTrials last refreshed its copy on 8 Nov 2026.
