This review study aimed to investigate the impacts of having Epstein Bar-Virus (EBV) positivity on therapeutic options of lymphomas. About one third of lymphomas are positive for EBV. Anyhow, existing therapeutic options are almost similar for treating lymphomas as either positive or negative for EBV. Future trends are thought to differ based on more better understanding of biology of EBV and to target such mechanisms that counteract or interfere with its pathogenesis including activation of apoptotic pathways or activating immunosuppression mechanisms.

It has been estimated that more than ninety percent of adult persons at global level have the potential of having latent EBV. Although latent EBV infection is likely to be highly occurred, but there is a low possibility to develop lymphoma associated with EBV [1].

EBV associated lymphomas are considered as a part of hematologic cancers that have in common latent EBV in tumor cells. Some endemic Burkitt lymphoma (BL) or HIV-associated lymphoma in central nervous system (CNS) are positive for EBV in almost all cases. Approximately one third of Hodgkin’s Lymphoma (HL) are positive for EBV, while it is a rare condition to have positive EBV in Diffuse large B-cell lymphoma (DLBCL) [1-3]. Certain conditions associated with immune alterations may lead to increased proportions for developing EBV associated lymphoma. These conditions include having HIV, immunodeficiency related to congenital factors, and immunosuppression conditions following organ transplantation. post-transplant immunosuppression, or chronic active EBV [4-6].

The discovery of EBV is due to 1964 [3]. At that time, oncogenic viruses were not attracting the attention to be of clinical significance. Denis Burkitt’s was the scientist who discovered this virus through determination of the most common tumour in childhood in Africa, while it was not known in the West [4]. It was not easy for scientific community to admit the relation between EBV and BL. This issue took several years to be accepted. It is worth to mention that sero-epidemiologic investigations showed that EBV was common among various human populations. Most people at global level are positive for EBV in form of asymptomatic infection [7,8]. It has been estimated that cancers due to viruses represent approximately 10% of cancer incidence at global level [9,10].

EBV is known by its ability to induce infectious mononucleosis (IM). EBV has contributed to several a wide spectrum of malignant lesions including BL, hemophagocytic lymphohistiocytosis, HL, gastric cancer and nasopharyngeal carcinoma [11,12].

Therapeutic Options

In the treatment of lymphomas associated with EBV, there are little therapeutic options that may lead to impact the virus within malignant cells. However, in the majority of cases, no differences in the therapeutic options have been identified according to the existence of EBV or not. Existing therapeutic approaches have made focus on interfering with biological aspects of EBV to target lymphomas associated with EBV as future therapeutic strategies. Thoughtfully, EBV-explicit methodologies incorporate reinforcing the antiviral/antitumor resistant reaction with antibodies or EBVexplicit cytotoxic T-lymphocytes, initiating lytic viral qualities to render the tumour cells helpless to antiviral treatments, and hindering the downstream prosurvival or antiapoptotic pathways that might be actuated by dormant EBV proteins. EBV-explicit cytotoxic T-cell imbuements have demonstrated viable in EBVrelated post transplantation lymphoproliferative disorder (EBVPTLD) and extending such assenting immunotherapies to other EBV-related malignancies is a place of dynamic research. In any case, other EBV-related lymphomas normally have progressively limited, less immunogenic varieties of viral antigens to restoratively focus with assenting immunotherapy contrasted and EBV-PTLD. Moreover, the threatening EBV-positive tumour cells of HL are dispersed in the midst of a thick penetrate of administrative T-cells, macrophages, and different cells that may hose the antitumor adequacy of supportive immunotherapy. Methodologies to beat these hindrances are regions of continuous preclinical and clinical examinations. Some rising ways to deal with EBV-related lymphomas incorporate the coupling of specialists that prompt lytic viral replication with antiherpesvirus operators, or the utilization of little particle inhibitors that square deteriorating pathways that are constitutively actuated by EBV. EBV antibodies appear to be generally encouraging for the treatment or counteractive action of EBV-related malignancies, as opposed to the avoidance of essential EBV contamination. EBV immunization preliminaries in patients with remaining or low-mass EBV-related malignancies or for the counteractive action of EBV-PTLD in EBV-seronegative patients anticipating strong organ transplantation are progressing [1].

In many occasions, the way to deal with EBV-positive lymphomas doesn’t contrast from EBV-negative lymphomas of a similar histology [13]. The special cases are with regards to investigational conventions or where a receptive immunotherapy approach is accessible [14,15].

At the point when EBV-positive lymphomas emerge in the setting of immunosuppression, enhancing the invulnerable deformity can aid the treatment of these lymphomas [16,17]. In HIV-related lymphomas, antiretroviral treatment is commonly fitting albeit potential medication communications and the impacts of chemotherapy on the capacity to keep up HAART treatment as far as sickness, heaving and mucositis must be considered with respect to the planning of antiretroviral treatment [5,18]. In any case, for EBV-related lymphomas in HIV patients, commencement of antiretroviral treatment alone is lacking for treatment. This is rather than AIDS-related Kaposi sarcoma where inception of antiretroviral treatment is frequently a standard methodology in patients who are asymptomatic or insignificantly symptomatic and are antiretroviral innocent [19,20]. In EBV-PTLD, select cases may profit by decrease of immunosuppression as the sole mediation or as a component of the treatment plan [3,21].


Therapeutic options for lymphomas associated with EBV are not greatly varied from those with negative lymphomas for EBV. However, existing therapeutic options include targeting biological aspects of EBV and may need future studies to be well established.
