Glutathione S-transferases(GSTs) are detoxification enzymes that provide critical defense against carcinogens. Our hypothesis was that altered frequencies of GST genotypes and environmental exposures might be associated with increased susceptibility for the development of esophageal cancer. A total of 100 esophageal cancer patients and 137 age and gender(More)
BACKGROUND AND PURPOSE Glioblastoma in the pediatric age group is relatively rare. As a result, it has been difficult to deduce any consistent clinico-radiological and pathological profiles on these patients. Also, the prognostic factors affecting the survival in pediatric glioblastoma are not as well defined as in adults. PATIENTS AND METHODS In this(More)
Cancer can have profound social and economic consequences for people in India, often leading to family impoverishment and societal inequity. Reported age-adjusted incidence rates for cancer are still quite low in the demographically young country. Slightly more than 1 million new cases of cancer are diagnosed every year in a population of 1.2 billion. In(More)
Early diagnosis and better prognosis of esophageal squamous cell carcinoma (ESCC) is still a challenge. Besides environmental risk factors, nutritional deficiencies have an established role in pathogenesis of ESCC. Folate deficiency and functional polymorphisms in folate metabolizing genes such as methylene tetrahydrofolate reductase (MTHFR) 677C>T may have(More)
Genetic variants in micro-RNAs (miRNA) have been shown to affect progression, diagnosis, and prognosis of various malignancies; however, their role in esophageal squamous cell carcinoma (ESCC) susceptibility is controversial. Therefore, we aimed to determine role of common genetic variants in cancer related pre-miRNA in susceptibility and survival outcome(More)
Phase I enzyme CYP1A1 metabolizes environmental carcinogens and a Msp1 T/C functional polymorphism in 3'UTR in its gene has been reported to influence the inducibilty of the enzyme. There are controversies regarding association of the polymorphism with risk of esophageal cancer in Chinese and Caucasian populations. Moreover, no study has been done in Indian(More)
Cranial nerve involvement in multiple myeloma and solitary plasmacytoma is rare. We report on two patients who developed cranial nerve palsy due to skull base plasmacytoma. Patient 1, a 55-year old man with multiple myeloma, developed right sixth cranial nerve palsy during a phase of chemotherapy. He had an intracranial plasmacytoma in the clival region and(More)
BACKGROUND Tumour necrosis factor-alpha (TNF-α) and nuclear factor of kappa light chain gene enhancer in activated B cells (NF-κB) play critical role in carcinogenesis processes like tumour initiation, proliferation, migration and invasion. Single nucleotide polymorphisms in TNF-α, NF-κB and its inhibitor IκB genes were shown to be associated with(More)
BACKGROUND AND AIM Survivin is an upregulated inhibitor of apoptosis protein in esophageal cancer (EC), and a promoter region polymorphism (-31G>C) in the survivin gene has been reported as a modulator of gene expression. We aim to explore the role of survivin -31G>C polymorphism in susceptibility and survival of EC patients in northern Indian population.(More)
PURPOSE The aim of this study was to ascertain whether diffusion tensor imaging (DTI) metrics fractional anisotropy (FA), mean diffusivity (MD), linear case (CL), planar case (CP), spherical case (CS)-can characterize a threshold dose and temporal evolution of changes in normal-appearing white matter (NAWM) of adults with low-grade gliomas (LGGs) treated(More)
