Elective versus Therapeutic Neck Dissection in Node-Negative Oral Cancer
Published in Niall MH McLeod, Peter A Brennan, 50 Landmark Papers every Oral & Maxillofacial Surgeon Should Know, 2020
Consenting adults aged between 18 and 75 years of age with histopathologically proven invasive SCC of the tongue, floor of mouth, or buccal mucosa that met the Union for International Cancer Control (UICC) criteria for tumour stage T1 and T2 lateralised to one side. Included patients had received no previous treatment, consented to transoral excision and had no prior history of head and neck cancer. Exclusion criteria were previous surgery in the head and neck region, upper alveolar or palatal cancers, large heterogenous leukoplakia, or diffuse oral submucous fibrosis.

Oral submucous fibrosis (OSF) is a chronic disorder, predominantly encountered in South Asian and Southeast Asian countries. It has been established that OSF is etiologically linked to the consumption of the Areca nut in flavored formulations or as an ingredient in the betel quid. Depigmentation of the lips may be the earliest feature to develop in the natural history of OSF (Figure 24.2).14

Buccal carcinoma typically occurs over the age of 40 years, although it may occur in younger patients,70 particularly when associated with the habit of betel chewing.71 Oral submucous fibrosis and lichen planus may involve the buccal mucosa, both being considered pre-malignant conditions.
A Discourse Analysis on Betel Nut Chewing in Hunan Province, China
Published in Journal of Psychoactive Drugs, 2021
In Mainland China, there are some empirical studies in the medical field. For example, Zhang et al. (2008) conducted a research in Xiangtan to investigate the chewers’ cognition about the side effects of betel nut chewing. The result showed that most of respondents did not realize the harmful relation between the chewing behavior and oral submucous fibrosis (OSF) and oral cancer. Zhou et al. (2014) examined the prevalence of betel nut chewing and the incidence of OSF among the commissioned and enlisted soldiers in Sanya, Hainan Province, and found that the oral diseases are relatively higher among the betel nut chewers. Zheng et al. (2015) based on the case of Danzhou residents, concluded that the oral health condition of betel quid chewers is more severe than that of non-chewers, and pointed out that chewing betel nuts is one of the most important causes for OSF. Recently, Du et al. (2016) by conducting the clinical examination, questionnaire and regular follow-up, investigated the effect of chewing fresh or dried betel nut on the incidence and canceration of oral mucosa disease in Haikou in Hainan Province. Their conclusion is that chewing dried betel nut is more pathogenic and carcinogenic than chewing fresh betel nut, and that the extremely harmful components of the dried betel nut synergistically play a vital role in the occurrence and carcinogenesis of oral mucosal diseases.

Although the highly addictive betel nut is classified as a carcinogen by the World Health Organization (WHO), the residents in Hunan Province regard it as part of their daily food intake. Over the years, the price of betel nuts has increased nearly ten-fold, and the number of people who chew betel nuts has also increased steadily, especially in Xiangtan City. According to a survey, 93.12% of residents in Xiangtan City, Hunan Province are betel nut chewers (Zhang et al., 2008). Hence, betel nuts have been reported to cause a high incidence of oral submucous fibrosis in this area (Shan Shan et al., 2012). Therefore, we conducted this research to explore newcomers’ acceptance of betel nut chewing and their possible dependence within this betel nut-dependent society.

Oral submucous fibrosis (OSMF), which was categorized as a premalignant condition by WHO in 1978, is now categorized as a potentially malignant disorder (PMD). PMDs has the prevalence rate of 0.2% to 0.5%, with malignant transformation potential of 0.13% to 17.5% (Poorani et al., 2014). Oral submucous fibrosis is defined as “an insidious chronic disease affecting any part of the oral cavity and sometimes the pharynx. Although occasionally preceded by and/or associated with vesicle formation, it is always associated with juxta-epithelial inflammatory reaction followed by fibro-elastic change of the lamina propria, with epithelial atrophy leading to stiffness of the oral mucosa and causing trismus and inability to eat” (Poorani et al., 2014, p. 11).
