Treatment regimens and survival among patients with head and neck squamous cell carcinoma from Mizo tribal population in northeast India - a single centre, retrospective cohort study.

Background: Patients with early-stage head and neck squamous cell carcinoma (HNSCC) are treated using a single-modality approach that involves either surgery (S) or radiotherapy (RT). Conversely, those with advanced-stage disease are treated using a multi-modality approach incorporating a combination of chemotherapy (CT), RT and S. In addition to behavioural factors, such as alcohol and tobacco use, clinical parameters, such as leukocyte and neutrophil counts and T and N classification, have been linked to the survival of patients with head and neck cancer.

Panel of significant risk factors predicts early stage gastric cancer and indication of poor prognostic association with pathogens and microsatellite stability.

Background: There are very few studies covering the epidemiological risk factors associated with Epstein Barr Virus (EBV) and Microsatellite stability for Gastric Cancer (GC) cases. Early diagnosis of GC through epidemiological risk factors is very necessary for the clinical assessment of GC. The aim of this study was to find out the major risk factors to predict GC in early stage and the impact of pathogen infection and MSI on survival rate of patients.

Pediatric leukemia could be driven predominantly by non-synonymous variants in mitochondrial complex V in Mizo population from Northeast India.

Leukemia is the most common childhood malignancy and studies had been carried out with promising revelations in its diagnosis and prognosis. However, majority of the studies are focused on nuclear alterations, while mitochondrial mutations are not well studied. Although there are studies of mitochondrial mutations in the adult leukemias, it does not represent the same for childhood malignancy.
