BACKGROUND AND AIM GBC is a lethal and multifaceted disease. Deleted in colorectal carcinoma (DCC) is a well known tumor suppressor gene. Recently a small genome-wide association study (GWAS) identified DCC to be significantly associated with gallbladder cancer (GBC) susceptibility in a Japanese population sample. However, the study sample size was small(More)
BACKGROUND/AIM Degradation of the basement membrane and extracellular matrix by matrix metalloproteinases (MMPs) is believed to be an essential step in the complicated process of hematogenous metastasis. Matrix metalloproteinase-7 (MMP-7) is a small secreted proteolytic enzyme with a broad substrate specificity, and its expression has been shown to be(More)
Intradural extramedullary metastases from tumours are a rare occurrence, accounting for less than 2 percent of all spinal metastases. We report a patient who presented with progressive paraparesis one and a half years after being operated for an poorly differentiated serous cystadenocarcinoma. Tumour mass decompression was carried out and the intradural(More)
Gallbladder cancer (GBC) is the most frequent biliary tract malignancy. Wide variations in GBC incidence and familial and epidemiological data suggest involvement of a genetic component in its etiopathogenesis. A systematic review of genetic association studies in GBC was performed by applying a meta-analysis approach and systematically reviewing PubMed(More)
BACKGROUND AND AIM PSCA is a tissue specific tumor suppressor or oncogene which has been found to be associated with several human tumors including gallbladder cancer. It is considered to be involved in the cell-proliferation inhibition and/or cell-death induction activity. Therefore, we aimed to investigate the role of PSCA gene polymorphisms in(More)
Gallbladder cancer (GBC) is a violent neoplasm associated with late diagnosis, unsatisfactory treatment, and poor prognosis. The disease shows complex interplay between multiple genetic variants. We analyzed 15 polymorphisms in nine genes involved in various pathways to find out combinations of genetic variants contributing to GBC risk. The genes included(More)
BACKGROUND Matrix metalloproteinase belong to family of pericellular collagenases which degrade extracellular matrix (ECM), and is involved in the modulation and susceptibility of various cancers. METHODOLOGY The present study included 410 gallbladder (GBC) cases and 230 healthy controls from North India. Study examined the associations of polymorphisms(More)
CD44 is an important marker for cancer stem cells. Germline variants in CD44 gene have been associated with susceptibility to breast and nasopharyngeal carcinomas but no study in gallbladder cancer (GBC) has been done yet. The present study included 405 GBC patients and 200 healthy controls from North India. Tagger SNPs for CD44 were selected from the GIH(More)
BACKGROUND Carcinoma of gallbladder (GBC) is an aggressive malignancy. The higher incidence of gallbladder cancer in women has been partly attributed to hormonal factors. Therefore the present study was designed to explore the role of genetic variants in estrogen (ESR1, ESR2) and progesterone (PGR) receptors in conferring risk of gallbladder cancer. (More)
