"Betel nut"

Manjiri Joshi, Mansi Tailor
BACKGROUND: Oral cancer is a major health problem in tobacco users worldwide and is one of the ten most common cancers. India alone accounts for 1/3 rd of the world's oral cancer and has a high rate of potentially malignant disorders (PMDs). The most common predisposing factors are smoking, smokeless tobacco, betel nut in quid form (pan), alcohol, spicy food, and sharp broken tooth. There are various tobacco-associated lesions (TALs) which can be diagnosed at very early stage. This study was conducted to rule out association of smoking and smokeless tobacco with occurrence of TALs and its dose-response relationship...

Background: Heavy metal pollution in farm soils is a grave concern in Taiwan. Previously, we found the incidence of oral cancer (OC) correlated positively with levels of nickel and arsenic in farm soils. Many OC patients have a second malignancy, among which esophageal cancer (EC) is the most common one in Taiwan. Objectives: We aimed to investigate whether these two cancers share some common risk factors. Methods: Taiwan began a compulsory national health insurance program in 1995. We used a database from this program to calculate the prevalence of EC and OC in Taiwan...

The immune system plays a key role in preventing tumor formation by recognizing and destroying malignant cells. For over a century, researchers have attempted to harness the immune response as a cancer treatment, although this approach has only recently achieved clinical success. Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide and is associated with cigarette smoking, alcohol consumption, betel nut use, and human papillomavirus infection. Unfortunately, worldwide mortality from HNSCC remains high, partially due to limits on therapy secondary to the significant morbidity associated with current treatments...

BACKGROUND: Oral cancer is a common malignancy that is shown to be causally associated with hereditary and acquired factors. ADAMTS14 is a member of the ADAMTS (a disintegrin-like and metalloproteinase domain with thrombospondin motifs) metalloproteinase family that plays an important role in extracellular matrix (ECM) assembly and degradation. Elevation or deficiency of certain ADAMTS proteinases has been known to be implicated in a wide range of pathological processes including atherosclerosis, arthritis, and cancer...

PURPOSE: Little is known about whether buccal mucosa elasticity influences the determination of surgical margins for buccal carcinomas. This study investigated whether there is a difference in elasticity of the buccal mucosa in patients with buccal carcinoma compared with controls without the disease. PATIENTS AND METHODS: A case-and-control study comprised of patients with buccal carcinoma and controls without the disease was conducted. In each patient, 2 gutta-percha points were attached to the buccal mucosa horizontally and examined twice by lateral cephalometry, once with the mouth closed and once during maximal mouth opening (MMO)...

Betel nut chewing is associated with oral cavity cancer. Radiotherapy is one of the therapeutic approaches. Here, we used miR-17-5p antisense oligonucleotides (AS-ODNs) and human apoptosis protein array to clarify which apoptosis-related proteins are increased or decreased by miR-17-5p in betel nut chewing- oral squamous cell carcinoma OC3 cells. Furthermore, miR-17-5p AS-ODN was used to evaluate the radio-sensitization effects both in vitro and in vivo. An OC3 xenograft tumor model in severe combined immunodeficiency mice was used to determine the effect of miR-17-5p AS ODN on tumor irradiation...

Early esophageal squamous cell neoplasias (ESCNs) are easily missed with conventional white-light endoscopy. This study aimed to assess whether early ESCNs have a spatial predilection and the patterns of recurrence after endoscopic treatment. We analyzed the circumferential and longitudinal location of early ESCNs, as well as their correlations with exposure to carcinogens in a cohort of 162 subjects with 248 early ESCNs; 219 of which were identified by screening and 29 by surveillance endoscopy. The circumferential location was identified using a clock-face orientation, and the longitudinal location was identified according to the distance from the incisor...

Betel nut is the second largest economic food product in Taiwan. In Southeast Asia, the habit of chewing betel nut seems to be highly correlated with oral submucous fibrosis and oral squamous cell carcinoma. Oral submucous fibrosis is characterized by abnormal accumulation of oral submucous collagen fibers and limitation of mouth opening. Although the mechanism responsible for tissue damage is still unknown, prolonged irritation caused by betel nut and tobacco is considered to be a major factor contributing to the pathogenesis of oral submucous fibrosis...

BACKGROUND: Smoking and betel nut chewing are well-known risk factors for head and neck squamous cell carcinoma (HNSCC). Smoking is also a strong prognosticator for patients with locally advanced HNSCC receiving induction chemotherapy. Smoking with or without betel nut chewing is a common practice in Asia. However, little is known regarding whether betel nut chewing can serve as a prognostic factor for smoking patients with locally advanced HNSCC receiving induction chemotherapy. The aim of this study was to evaluate the prognostic impact of betel nut chewing in such patients receiving induction chemotherapy with docetaxel, cisplatin, and fluorouracil (TPF)...

INTRODUCTION: Nitric oxide (NO), a free radical, acts as a signalling molecule affecting numerous physiological and pathological processes. Role of nitric oxide as a mediator in tobacco related habits and the resultant oral lichenoid reactions was assessed. AIM: The aim of the study is to evaluate and compare the salivary nitric oxide levels in normal patients with that of smokers, tobacco chewers and patients with oral lichenoid reactions. MATERIALS AND METHODS: One hundred and twenty patients were enrolled in the study which included 30 healthy patients without any chronic inflammatory lesion and habit as controls (group I), 30 smokers without the habit of tobacco/betel nut chewing and any oral lesion (group II), 30 tobacco chewers without the habit of smoking and any oral lesion (group III) and 30 histologically confirmed cases of oral lichenoid reaction with the habit of tobacco usage (group IV)...
