Extranodal natural-killer/T-cell lymphoma, nasal type: An immunomorphological study from a regional cancer institute in India.

Introduction: Extranodal natural-killer/T-cell lymphoma, nasal type (ENKTL), is a rare, aggressive, predominantly extranodal non-Hodgkin lymphoma (NHL) of putative natural-killer (NK) cell and rarely T-cell origin, always associated with Epstein-Barr virus (EBV) infection and characterized by highly distinctive histopathological features with predilection for the upper aerodigestive tract. While the nasal cavity is the prototypical site, less frequently extranasal ENKTL can also occur. The objective of this case series is to study the immunomorphological features of ENKTL from a tertiary cancer centre as the data are sparse from India despite it being a distinct entity with characteristic clinicopathological features.

Operative Outcomes of Minimally Invasive Esophagectomy versus Open Esophagectomy for Resectable Esophageal Cancer.

Relationship between promoter methylation & tissue expression of MGMT gene in ovarian cancer.

Background & Objectives: Epigenetic alterations, in addition to multiple gene abnormalities, are involved in the genesis and progression of human cancers. Aberrant methylation of CpG islands within promoter regions is associated with transcriptional inactivation of various tumour suppressor genes. O 6-methyguanine-DNA methyltransferase (MGMT) is a DNA repair gene that removes mutagenic and cytotoxic adducts from the O 6 -position of guanine induced by alkylating agents.

Pediatric Hodgkin lymphoma in a South Indian regional cancer center: its immunomorphology, tumor-associated macrophages, and association with Epstein-Barr virus.

Pediatric Hodgkin lymphoma (HL) comprises approximately a fifth of all patients with HL in India. Seventy-four cases of pediatric classical Hodgkin Lymphoma (cHL) from a regional cancer center in southern India were analyzed on a tissue microarray (TMA) for the stage of B-cell differentiation of the Hodgkin/Reed Sternberg (HRS) cell by immunohistochemistry (IHC) using CD10, bcl6, MUM1/IRF4, and CD 138. Fifty-two of seventy-four (70.
