    Gastric cancer is one of the most common cancers and the second leading cause of cancer‑associated mortality worldwide. Recurrence, metastasis and resistance to drug treatment are the main barrier to survival of patients with advanced stage gastric cancer. Further study of the molecular mechanisms involved will improve the therapeutic options for gastric cancer. Read More

    Expression of Master Regulators of T-cell, Helper T-cell and Follicular Helper T-cell Differentiation in Angioimmunoblastic T-cell Lymphoma.

    Departments of Hematology and Laboratory Medicine, Aiseikai Yamashina Hospital, Japan.
    Objective It has been postulated that the normal counterpart of angioimmunoblastic T-cell lymphoma (AITL) is the follicular helper T-cell (TFH). Recent immunological studies have identified several transcription factors responsible for T-cell differentiation. The master regulators associated with T-cell, helper T-cell (Th), and TFH differentiation are reportedly BCL11B, Th-POK, and BCL6, respectively. Read More

    Study of association of Epstein-Barr virus in lymphomas by Epstein-Barr virus-encoded RNA hybridization: An Indian perspective from a tertiary care cancer institute.
    Indian J Pathol Microbiol 2017 Jul-Sep;60(3):341-349
    Department of Pathology, Rajiv Gandhi Cancer Institute and Research Centre, New Delhi, India.
    Background: The Epstein-Barr virus (EBV), also called human herpesvirus 4, is a virus of the herpes family. The EBV-associated lymphomas include Burkitt lymphoma, classic Hodgkin lymphoma (HL), lymphomas arising in immunocompromised individuals, peripheral T-cell lymphomas, angioimmunoblastic T-cell lymphoma, extranodal nasal-type natural killer/T-cell lymphoma, and other rare histotypes.

    Objective: The present study evaluated the role of EBV as an etiologic agent in various lymphomas and determined an Indian perspective in a tertiary care cancer center compared to that of Western literature. Read More
