Integrating novel drugs to chemoimmunotherapy in diffuse large B-cell lymphoma.

Diffuse Large B-cell Lymphoma (DLBCL) is the most common aggressive non-Hodgkin lymphoma (NHL), with an incidence in Europe of 3.8/100.000/year. A multi-drugs chemoimmunotherapy regimen, containing rituximab, cyclophosphamide, vincristine, doxorubicin and prednisone (R-CHOP) administrated every 21 days, is the standard therapy for DLBCL patients. The discovery of several biological features of DLBCL has encouraged the introduction of novel drugs in the treatment. Areas covered: In this article, the use of standard therapies will be reviewed and will be investigated adoption of novel drugs such as Bortezomib, Bruton's tyrosine kinase, IMiDs, Venetoclax, mTOR inhibitors and other biological agents. Expert commentary: A better knowledge of the biology of DLBCL is mandatory to tailor treatment and to ameliorate the poor prognosis of DLBCL. The addition of novel drugs to standard RCHOP should represent a modern approach in the treatment of DLBCL. Ibrutinib and lenalidomide showed important results in DLBCL and the integration of these drugs in first line treatment is under investigation. Despite encouraging results using novel drugs in the setting of relapsed/refractory DLBCL, the rate of failures still remains at 40%; for these reason, continued participation in clinical trials should be encouraged.
