The research group focuses on the study of lymphomas that affect immunosuppressed patients, both in clinical and genetic aspects. We have made important contributions in this field and our current objective is to unveil genetic and epigenetic characteristics of lymphoid neoplasms that occur mainly in immunosuppressed patients. The purpose is to find markers for a more accurate management of these patients. Furthermore, we aim to implement liquid biopsy as a tool for diagnosis and follow-up of aggressive lymphomas. 


Our research lines are:

-   Genetic studies on of HIV-related lymphomas

Diffuse large B-cell lymphoma is the most frequent type of lymphoma in the HIV-infected population. HIV-infected patients are treated with the same regimens as the HIV-noninfected and similar responses are obtained but their survival is lower due to the higher susceptibility to infections and secondary neoplasms. The biological context of HIV-related lymphomas and the etiopathogenesis may be distinct from HIV-non-infected lymphomas. The disclosure of the transcriptome of HIV-DLBCL and the altered signaling pathways could allow to define prognostic factors, as well as to identify drugs that could revert the abnormal cell functioning. Furtheremor, It would be expected to change the diagnostic tools and prognostic algorithms and to define new and more effective targeted therapies for HIV-DLBCL patients.

-   Liquid biopsy in aggressive lymphomas.

The diagnosis of DLBCL sometimes can be difficult to make it applying all the technics to properly classify it, because not always enough material is obtained from the biopsy. Therefore, a non-invasive method, such as a liquid biopsy could suppose an important advance in the clinical practice for the diagnosis and follow-up of DLBCL. This technique could be useful to diagnose DLBCL earlier, and in a complete and accurate manner than only with tissue biopsy. Moreover, liquid biopsy could be used to unveil treatment resistance, as well as to follow-up the patients and detect lymphoma relapses earlier.

-   Genetic studies on plasmablastic lymphoma.

Plasmablastic lymphoma (PBL) is a rare B-cell lymphoid neoplasm especially affecting immunocompromised individuals. It is an entity with poor prognosis despite treatment. Unlike other lymphomas, the genetic and epigenetic alterations have not been scarcely studied in patients with PBL. In collaboration with Professor Georg Lenz, we have created the “International Consortium of Plasmablastic Lymphoma” a working group to study clinic, genetic and epigenetic landscape of PBL. The identification of abnormalities in the genome, transcriptome and epigenome of PBL will lead to substantial advances in the knowledge of the biology of PBL and it is expected to change the diagnostic tools and prognostic algorithms, finally helping defining the best therapies or to design new therapeutic.

-   Genetic characteristics of Castleman disease.

Castleman disease (CD) is a rare disease, characterized by a non-clonal lymphoid proliferation with an heterogenous clinical course. Some patients have very favorable outcomes whereas other develop highly progressive disease and die within weeks, some developing an aggressive lymphoma. There are few reports on the underling genomic alterations associated with CD and so far, it is unknown the etiology of this disease. We expect to define the transcriptional programs, the cellular signaling pathways and the epigenetic alterations associated with this lymphoproliferative disorder. The results of this research hopefully will identify new CD biomarkers and will support the design of new treatments and target therapies that eventually will improve the prognosis and quality of life of patients with CD.

Plasma EBV-load as an early biomarker and prognostic factor of HIV-related lymphomas.

Clin. Infect. Dis. 29 Jun 2018, . Epub 29 Jun 2018
Epstein-Barr virus (EBV) has been implicated in lymphomagenesis and can be found infecting tumor cells and in plasma at lymphoma diagnosis, especially in HIV-infected patients. Our aim was to evaluate the usefulness of plasma EBV-load as biomarker and prognostic factor in HIV-related lymphomas.

GESIDA/PETHEMA recommendations on the diagnosis and treatment of lymphomas in patients infected by the human immunodeficiency virus.

Med Clin (Barc) 13 Jul 2018, 151 (1) 39.e1-39.e17. Epub 19 Jan 2018
The incidence of non-Hodgkin's lymphoma and Hodgkin's lymphoma is higher in patients with HIV infection than in the general population. Following the introduction of combination antiretroviral therapy (cART), the prognostic significance of HIV-related variables has decreased, and lymphoma-related factors have become more pronounced. Currently, treatments for lymphomas in HIV-infected patients do not differ from those used in the general population. However, differentiating characteristics of seropositive patients, such as the need for cART and specific prophylaxis and treatment of certain opportunistic infections, should be considered. This document updates recommendations on the diagnosis and treatment of lymphomas in HIV infected patients published by GESIDA/PETHEMA in 2008.

HIV-infection has no prognostic impact on advanced-stage Hodgkin lymphoma.

AIDS 19 Jun 2017, 31 (10) 1445-1449.
Classical Hodgkin lymphoma (cHL) is a non-AIDS-defining cancer with a good response to chemotherapy in the combined antiretroviral therapy (cART) era. The aim of the present study was to compare the characteristics, the response to treatment and the survival of advanced-stage cHL treated with adriamycin, bleomycin, vinblastine and dacarbazine (ABVD) between cART-treated HIV-positive and HIV-negative patients.

HIV-infection impact on clinical-biological features and outcome of diffuse large B-cell lymphoma treated with R-CHOP in the combination antiretroviral therapy era.

AIDS 24 Apr 2015, 29 (7) 811-8. Epub 27 Feb 2015
Since the introduction of combination antiretroviral therapy (cART) patients with HIV-related diffuse large B-cell lymphoma (DLBCL) show better control of immunosuppression, which may have an impact on the characteristics and prognosis of the disease. We aimed to compare the clinical presentation and prognosis of patients with HIV-related and HIV-unrelated DLBCL treated with rituximab, cyclophosphamide, adriamycin, vincristine, and prednisone (R-CHOP) in the cART era.
