Ketone Bodies Are Potential Prognostic Biomarkers in Relapsed/Refractory Diffuse Large B-Cell Lymphoma: Results from the R2-GDP-GOTEL Trial.

Patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) who are ineligible for high-dose chemotherapy have limited treatment options and poor life expectancy. The purpose of this study is to identify a serum metabolomic profile that may be predictive of outcome in patients with R/R-DLBCL. This study included 69 R/R DLBCL patients from the R2-GDP-GOTEL trial (EudraCT 2014-001620-299).

CD8+ NKs as a potential biomarker of complete response and survival with lenalidomide plus R-GDP in the R2-GDP-GOTEL trial in recurrent/refractory diffuse large B cell lymphoma.

Background: Diffuse large B cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma worldwide. DLBCL is an aggressive disease that can be cured with upfront standard chemoimmunotherapy schedules. However, in approximately 35-40% of the patients DLBCL relapses, and therefore, especially in this setting, the search for new prognostic and predictive biomarkers is an urgent need.

Lenalidomide plus R-GDP (R2-GDP) in Relapsed/Refractory Diffuse Large B-Cell Lymphoma: Final Results of the R2-GDP-GOTEL Trial and Immune Biomarker Subanalysis.

Purpose: New therapeutic options are needed in relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL). Lenalidomide-based schedules can reverse rituximab refractoriness in lymphoma.

Patients And Methods: In the phase II R2-GDP trial, 78 patients unsuitable for autologous stem cell transplant received treatment with the following schedule: lenalidomide 10 mg Days (D)1-14, rituximab 375 mg/m2 D1, cisplatin 60 mg/m2 D1, gemcitabine 750 mg/m2 D1 and D8, and dexamethasone 20 mg D1-3, up to 6 cycles (induction phase), followed by lenalidomide 10 mg (or last lenalidomide dose received) D1-21 every 28 days (maintenance phase).

Circulating myeloid-derived suppressor cells and regulatory T cells as immunological biomarkers in refractory/relapsed diffuse large B-cell lymphoma: translational results from the R2-GDP-GOTEL trial.

Background: The search for immunological markers with ability of predicting clinical outcome is a priority in lymphomas, and in cancer in general. It is well known that some immunomodulatory cells, such as myeloid derived suppressor cells (MDSCs) or regulatory T cells (Tregs), are recruited by tumors, jeopardizing antitumor immunosurveillance. In this work, we have studied blood levels of these immunosuppressive cells in patients with relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL), prior to and along the course of the experimental rituximab, gemcitabine, dexamethasone, and cisplatin (R2-GDP) schedule, as a translational substudy of the R2-GDP-GOTEL trial (EudraCT Number: 2014-001620-29), which included lenalidomide as an immunomodulator.

Impact of age group on febrile neutropenia risk assessment and management in patients with diffuse large B-cell lymphoma treated with R-CHOP regimens.

Unlabelled: Improving the management of elderly patients with lymphoma is of increasing relevance. One thousand one hundred thirteen patients with diffuse large B-cell lymphoma (DLBCL) received rituximab (R)-CHOP (cyclophosphamide, doxorubicin [hydroxydaunorubicin], vincristine [Oncovin], and prednisone) in an observational study. Both older and younger patients failed to receive growth factor support in accordance with international guidelines; patients 65 years and older were more susceptible to febrile neutropenia (FN) and its consequences.

Darbepoetin alfa administration in patients with non-Hodgkin lymphoma and chemotherapy-induced anemia receiving (±R) CHOP.

IMPACT NHL was a multicenter, observational study in adults with non-Hodgkin lymphoma receiving CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) chemotherapy with or without rituximab. Erythropoietin-stimulating agent treatment was given according to routine clinical practice and physician preference. In a subanalysis, outcomes were evaluated in 207 patients who received darbepoetin alfa (DA).

Impact of febrile neutropenia on R-CHOP chemotherapy delivery and hospitalizations among patients with diffuse large B-cell lymphoma.

Purpose: This analysis from an observational study of clinical practice describes the impact of febrile neutropenia (FN) on chemotherapy delivery and hospitalizations.

Methods: Adults with diffuse large B-cell lymphoma (DLBCL) scheduled to receive ≥ 3 cycles of 2- or 3-weekly CHOP with rituximab (R-CHOP-14/21) were eligible. Primary outcome was incidence of FN.
