Abstract
BACKGROUND Chewing betel nuts can increase the risk of periodontal disease severity and potentially become malignant in the oral cavity. OBJECTIVE This study aimed to investigate the effect of the duration and frequency of betel quid chewing behaviour on periodontitis severity and the life quality of people in Tanini Village, Kupang Regency, Indonesia. METHODS The type of this study was an analytic observational study with a cross-sectional design. We used a questionnaire to obtain sociodemographic data. Oral Health Survey Basic Methods were used to measure debris index, plaque index, bleeding on probing, loss of attachment, and pocket depth. Behaviour and quality of life were measured by questionnaire and WHOQOL-BREF method as well. RESULTS The largest number of respondents were male. Duration of chewing had a significant relationship with the frequency of chewing and periodontal status. Periodontitis was higher compared to all categories. The lifestyle of the community greatly influenced their behaviour in betel nut chewing and also affected the severity of their periodontitis and OHIs significantly. CONCLUSION The lifestyle of betel nut chewing of the people in Tanini Village, greatly influences their behaviour. Prolonged and excessive use of betel nut induced significant adverse effects on human health. The longer and more often chew betel or areca nut, the higher the incidence of periodontitis, which significantly affects the quality of life as there is a possibility of the development of carcinogenesis, particularly in the oral cavity.

Abstract
The major predisposing factors of developing oral cancer include smoking, alcohol drinking, and betel quid chewing. Betel quid chewing could cause the abrasion and damage of oral mucosa by crude fibers, chemical insults by additive slaked lime, and arecoline from areca nut. These would lead to the local consequence of oral submucosal fibrosis, which is regarded clinically as a precancer lesion and a major cause of trismus. In addition, the components and additives in betel quid contain chemical toxins and carcinogens, which would further affect the oral mucosa and gradually develop a malignancy. Following literature review, aside from having a greater total tumor burden and more local diseases in the oral cavity and digestive tract, patients with betel quid-related oral cancer also have more systemic diseases from metabolic syndrome, hypertension, cardiovascular disease, type II diabetes mellitus, and obesity than those without this habit. In conclusion, those patients who have the history of smoking, alcohol drinking, and betel quid chewing would present much more unique clinical characteristics than those who only have a history of smoking and alcohol drinking. More attention should therefore be paid to pretreatment evaluation, treatment strategy, and posttreatment follow-up among betel quid chewers.

A Systematic Review and Meta-Analysis. Cancers (Basel) 2022; 14:cancers14081886. [PMID: 35454794 PMCID: PMC9029651 DOI: 10.3390/cancers14081886] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Revised: 04/05/2022] [Accepted: 04/06/2022] [Indexed: 02/04/2023] Open
Abstract
Simple Summary Oral cancer was considered a disease of old age. However, there has been a recent surge in the incidence of oral cancer in young individuals. Age dependence on survival outcomes such as overall survival, disease-free survival, recurrence, distant metastasis and second primary in surgically treated oral cancer has been investigated several times and the results differ. This systematic review and meta-analysis has been conducted to address this concern. The results of the present research may facilitate age-dependent prognosis stratification, which would assist in treatment planning in oral cancer patients. Abstract This systematic review and meta-analysis aims to address whether age can be a determinant of overall survival (OS), disease-free survival (DFS), recurrence, distant metastasis (DM) and second primary (SP) in surgically treated oral and oropharyngeal squamous cell carcinoma (OOPSCC). A total of 4981 cases and 44254 controls from 25 comparative observational studies were included in the analysis. A significantly better OS (matched subgroup analysis: OR 1.64; 95% CI 1.31–2.04, overall analysis: OR 1.48; 95% CI 1.09–2.01) was observed in young patients compared to older adults, with heterogeneity ranging from moderate to severe. Worse DFS (unmatched subgroup analysis OR 0.43; 95% CI 0.27–0.68) was observed in young patients compared to older adults with minimal to moderate heterogeneity. The frequency of recurrence (OR 1.49; 95% CI 1.10–2.02) and DM (OR 1.83; 95% CI 1.10–3.03) was significantly higher in the young patients, as found in unmatched and matched subgroup analysis, with the least heterogeneities. Young age can be considered as an independent prognostic factor for recurrence and distant metastases in OOP-SCC. Larger and methodologically robust observational studies with longer follow-up are needed to establish the definitive role of age as an independent prognostic factor on OS and DFS in OOPSCC.

Developing a Stacked Ensemble-Based Classification Scheme to Predict Second Primary Cancers in Head and Neck Cancer Survivors. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182312499. [PMID: 34886225 PMCID: PMC8657249 DOI: 10.3390/ijerph182312499] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/16/2021] [Revised: 11/21/2021] [Accepted: 11/25/2021] [Indexed: 12/16/2022]
Abstract
Despite a considerable expansion in the present therapeutic repertoire for other malignancy managements, mortality from head and neck cancer (HNC) has not significantly improved in recent decades. Moreover, the second primary cancer (SPC) diagnoses increased in patients with HNC, but studies providing evidence to support SPCs prediction in HNC are lacking. Several base classifiers are integrated forming an ensemble meta-classifier using a stacked ensemble method to predict SPCs and find out relevant risk features in patients with HNC. The balanced accuracy and area under the curve (AUC) are over 0.761 and 0.847, with an approximately 2% and 3% increase, respectively, compared to the best individual base classifier. Our study found the top six ensemble risk features, such as body mass index, primary site of HNC, clinical nodal (N) status, primary site surgical margins, sex, and pathologic nodal (N) status. This will help clinicians screen HNC survivors before SPCs occur.

Abstract
OBJECTIVE Head and neck cancer (HNC) is the sixth leading cancer worldwide with approximately 600,000 new cases per year. Several studies suggest that HNC survivors may have an increased risk of developing second primary cancers (SPCs). A systematic review and meta-analysis was performed aiming to quantify the overall and site-specific risk of metachronous SPCs in HNC survivors. METHODS PubMed, Web of Science and Scopus were searched to identify studies published until October 2019. Studies investigating the standardised incidence ratio (SIR) of metachronous SPC were included. A random-effects meta-analysis was performed to calculate the overall and site-specific SIRs. Newcastle-Ottawa Scale was used to assess the study's quality. Heterogeneity was quantified using the I2 statistics and explored using meta-regression. RESULTS Twenty-six studies were included in the systematic review. Studies differed by the definition of metachronous SPC used. For the meta-analyses, the studies were grouped according to these definitions. In the three groups, the overall risk of metachronous SPC was increased. The highest SPC risk was for oropharynx, oesophagus and lung. CONCLUSIONS Head and neck cancer survivors are at increased overall risk of metachronous SPCs. The canonical upper aerodigestive sites, HNLE (head and neck, oesophagus and lung), were the SPC sites with the highest risk. IMPLICATION FOR CANCER SURVIVORS Our results emphasise the importance of targeted surveillance strategies aimed at early detection and tertiary preventive interventions.

Abstract
How long esophageal screening should be performed for, and on which sub-groups of head and neck cancer (HNC) survivors, remains uncertain. This retrospective study analyzed data from the Taiwan National Health Insurance Research Database from 1999 to 2013. A total of 68,131 newly- diagnosed HNC patients were enrolled. Subjects who received esophageal endoscopic screening within 6 months after their diagnosis date of index HNC were identified. The incidence trends of secondary primary EC were analyzed using a Cochran-Armitage trend test. Among the 9,707 patients who received index esophageal endoscopy screening, 101 (1.0%) cases of synchronous EC were diagnosed. The 5- and 10-year cumulative incidence rates of metachronous ECs were 1.4% and 2.7%, respectively in those with an initial negative index endoscopic finding. Patients with oropharynx or hypopharynx cancers were at significantly higher risk of developing metachronous ECs compared with those with oral or larynx cancers (10-year incidence rate: 3.3% vs. 0.9%, respectively; hazard ratio: 2.15; 95% confidence intervals: 1.57-2.96). Metachronous EC continues to develop in patients with HNC even at 10-years after treatment for primary HNC. HNC patients, especially those with oropharynx or hypopharynx cancer, may require long-term endoscopic surveillance.

Abstract
After their initial presentation of oral squamous cell carcinoma (SCC), patients have a lifelong risk of developing another new SCC of the head and neck. The aim of this study was to establish second primary rates, baseline characteristics (site, clinical or pathological stage, and smoking and alcohol history), timing, presentation, treatment, and outcomes. From the regional unit we analysed records of patients treated with curative intent for their first oral cancer between 2002 and 2007 inclusive. All patients had had at least 10 years of follow up either to death or the end of 2017. A total of 347 patients had been treated with curative intent, and of them, 29 had a second primary at a median (IQR) of 52 (30-79) months after the index operation. The incidence of developing a second primary tumour within two years was 1.7% (95% CI: 0.7% to 3.7%), within five years was 4.9% (95% CI: 2.9% to 7.7%), and within 10 years was 7.8% (95% CI: 5.1% to 11.1%). Early stage of first cancer was the only significant factor (p=0.001) for development of a second primary within 10 years, reflecting survivorship. Most second primaries (21 patients) were staged as early, and by visual inspection. Most (n=20) were within the oral cavity, one of which overlapped the oropharynx; eight others were in the oropharynx, and one in the larynx. Most patients (n=22) were treated by operation with curative intent. Three were treated palliatively. Patients need to be aware of the risk of a second primary and, as most are in the mouth or oropharynx, there is a role for surveillance by primary dental care practitioners.

Abstract
OBJECTIVES The improved survival of patients with oral cavity cancer (OCC) has generated interest in factors affecting survivorship, particularly among second primary cancer (SPC) patients. This study aimed to assess the incidence, patterns, and risk factors for SPC after OCC treatment in the Korean population. MATERIALS AND METHODS Data from 15,261 patients with OCC (ICD-O: C01-C06) identified between 1993 and 2014 were extracted from the Korean Central Cancer Registry. The standardized incidence ratio (SIR) for SPC after index OCC was calculated, and Poisson regression analysis was performed to evaluate the risk factors for SPC among survivors. RESULTS The overall SIR for SPC among OCC survivors was 1.47 (95% confidence interval [CI] 1.39-1.56). SIR differed by sex (male: 1.51 vs. female: 1.37), age at diagnosis (<45 years: 2.47 vs. 45-64 years: 1.68 vs. ≥ 65 years: 1.10), index OCC subsite (floor of mouth: 1.95 vs. gum: 1.30), follow-up duration (6-23 months: 1.64 vs. 24-59 months: 1.51 vs. 60-119 months: 1.48 vs. ≥ 120 months: 1.24), histological OCC type (salivary gland malignancy: 1.77 vs. squamous cell carcinoma: 1.44 vs. others: 1.47), and radiation history (any: 1.94 vs. no radiation: 1.37). The risk factors for SPC development among OCC survivors included younger age at diagnosis and history of radiation therapy. CONCLUSION OCC survivors have significantly increased risks of SPCs, exhibiting distinctive site distributions and chronological patterns. These patients would benefit from an SPC surveillance protocol.

Abstract
OBJECTIVE To investigate the risk for second primary cancer in the hypopharynx and esophagus (SPC-HE) among individuals with an initial oral/oropharyngeal cancer. MATERIALS AND METHODS Mass screening data from Taiwan (2004-2009) included individuals who were ≥18 years old and smoked cigarettes and/or chewed betel quid. Occurrence of SPC-HE was monitored until December 31, 2014. Results were expressed as adjusted relative risk (aRR) and 95% confidence interval (CI). RESULTS One hundred and fifty-eight out of 4,494 subjects with oral cancer developed SPC-HE (incidence rate: 6.47 per 1,000 person-years). Relative to patients with primary cancers in the lip, the risk of an SPC-HE was higher in patients with primary cancers in oropharynx (aRR: 19.98, 95% CI: 4.72-84.55), floor of mouth (aRR: 12.13, 95% CI: 2.67-55.15), and hard palate (aRR: 7.31, 95% CI: 1.65-32.37), but not in patients with cancers in tongue (aRR: 3.67, 95% CI: 0.89-15.17) or gum (aRR: 3.99, 95% CI: 0.92-17.35). Regression analyses also showed the risk of an SPC-HE was greater in alcohol drinkers than those who did not (aRR: 1.65, 95% CI: 1.10-2.48). CONCLUSIONS Compared with the initial cancer in the lip, patients with a cancer in the oropharynx, floor of mouth, and hard palate had a higher risk for the SPC-HE.

Betel nut chewing history is an independent prognosticator for smoking patients with locally advanced stage IV head and neck squamous cell carcinoma receiving induction chemotherapy with docetaxel, cisplatin, and fluorouracil. World J Surg Oncol 2016; 14:86. [PMID: 27001663 PMCID: PMC4802661 DOI: 10.1186/s12957-016-0844-2] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2015] [Accepted: 03/14/2016] [Indexed: 11/10/2022] Open
Abstract
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). Methods From January 2010 to December 2012, we retrospectively analyzed 162 smoking patients with locally advanced HNSCC who received induction chemotherapy with TPF at our institution. Background characteristics, including a history of betel nut chewing, were analyzed as potential prognostic factors. Results Among the 162 smoking patients, 131 patients (81 %) were betel nut chewers, while 31 (19 %) were non-betel nut chewers. One hundred fifty-six (96 %) were men, and 6 (4 %) were women. The median age was 53 years. The overall response rates to induction chemotherapy were 57 and 77 % in patients with and without betel nut chewing history, respectively (P = 0.038). The 2-year progression survival rates were 37 and 67 % in patients with and without betel nut chewing history, respectively (P = 0.004). The 2-year overall survival rates were 47 and 71 % in patients with and without betel nut chewing history, respectively (P = 0.017). Betel nut chewing history was independently associated with a poor response to induction chemotherapy, an inferior progression-free survival rate, and a poor overall survival rate. Conclusions Our results indicate that betel nut chewing history is independently associated with poor prognosis in smoking patients with locally advanced HNSCC receiving induction chemotherapy with TPF. Further investigation is warranted to explain this effect of betel nut chewing history on these patients’ prognosis.

Abstract
Oral submucous fibrosis (OSF) is a premalignant condition caused by betel chewing. It is very common in Southeast Asia but has started to spread to Europe and North America. OSF can lead to squamous cell carcinoma, a risk that is further increased by concomitant tobacco consumption. OSF is a diagnosis based on clinical symptoms and confirmation by histopathology. Hypovascularity leading to blanching of the oral mucosa, staining of teeth and gingiva, and trismus are major symptoms. Major constituents of betel quid are arecoline from betel nuts and copper, which are responsible for fibroblast dysfunction and fibrosis. A variety of extracellular and intracellular signaling pathways might be involved. Treatment of OSF is difficult, as not many large, randomized controlled trials have been conducted. The principal actions of drug therapy include antifibrotic, anti-inflammatory, and antioxygen radical mechanisms. Potential new drugs are on the horizon. Surgery may be necessary in advanced cases of trismus. Prevention is most important, as no healing can be achieved with available treatments.

Abstract
OBJECTIVES We sought to investigate whether there is evidence of field cancerization in patients with oral cavity squamous cell carcinoma (OSCC) enrolled in a betel quid chewing area. We also assessed whether betel quid chewing is an independent risk factor for field cancerization in OSCC patients. METHODS We retrospectively examined the records of 1570 OSCC patients who underwent radical tumor resection between 1996 and 2011. A total of 1243 study participants (79%) had a positive history of betel quid chewing before surgery. Of the 767 patients treated with surgery alone, 599 (78%) were preoperative chewers, whereas a history of preoperative betel quid chewing was identified in 644 (80%) of the 803 patients who received adjuvant therapy. The 5-year control, survival, and second primary tumors (SPTs) rates served as the main outcome measures. RESULTS Regardless of the treatment modality, more than 70% of the SPTs were located in the oral cavity or soft palate. Despite a similar risk profile in terms of tumor depth, lymph node metastasis, and pathological margin status, preoperative chewers showed a significantly higher incidence of 5-year SPTs and local recurrences compared with non-chewers. Moreover, multivariate analysis demonstrated that preoperative betel quid chewing was an independent prognostic factor for 5-year local control and SPTs occurrence rates. CONCLUSIONS Our results demonstrate that preoperative betel quid chewers had a higher incidence of local recurrence and SPTs than non-chewers, suggesting that field cancerization may occur in OSCC patients with a history of betel quid chewing.

Abstract
Human papilloma virus (HPV) has been detected in some upper aerodigestive tract tumors, but the correlation between HPV and these tumors is not well understood. There is also some controversy regarding this correlation because a large variation in the prevalence of HPV in these tumors has been reported. To discuss the impact of HPV infection on upper aerodigestive tract tumors, this review estimated systematically the prevalence and risk of HPV in upper aerodigestive tract tumors from studies published between 1982 and 2012. In total, 418 articles were selected, which included 273 studies on the head and neck and 145 studies on esophageal squamous cell carcinoma. The overall prevalence of HPV in the 5,467 head and neck squamous cell carcinoma specimens was 36.3%. HPV was detected more frequently in the Americas (40%), than in Asia (38.6%), Europe (32%), or others regions (30.5%). The prevalence of HPV was significantly higher in oropharyngeal (48.5%) than in oral (32.5%), laryngeal (30.7%), and unselected head and neck squamous cell carcinoma (33.3%) (P < 0.001). The pooled prevalence of HPV in the 6,912 esophageal squamous cell carcinoma cases was 38.9% and it was significantly higher in China (44%) versus other regions (31.3%) (P < 0.05). Meta-analysis showed that head and neck and esophageal squamous cell carcinoma are associated with HPV infection (combined OR: 3.58, OR for head and neck and esophageal squamous cell carcinoma: 4.20). These findings suggest that HPV might be linked etiologically to the development of some upper aerodigestive tract tumors.

Abstract
Background Head and neck cancer (HNC) is associated with a high rate of developing second primary malignancies(SPMs). But the impact on survival remains poorly understood before. Therefore, we want to estimate the impact of SPMs on HNC survivors. Methods and Findings Between 1986 and 2008, a total of 9,996 SPMs were recorded for 93,891 patients with an initial diagnosis of HNC by the Taiwan Cancer Registry. Patients were followed with national death registry database to 2011.Using the Kaplan–Meier method, a time-dependent covariate was employed to compare the survival rates between patients with and without SPMs. A Cox proportional hazards model that treated age and sex as confounders was used to examine the hazard ratios of SPMs. The relative survival rates were calculated using age- and sex-specific life tables for the population. Parametric mixture cure fraction models were then employed to estimate the percentage of cancer survivors who would be cured. Use of the Kaplan–Meier method showed that the crude survival rates differed significantly for patients with and patients without SPMs (log-rank test <0.01). For the results of Cox proportional hazards regression analysis, SPMs had a significant influence on survival rates with univariate (HR 2.59,95% CI 2.53to 2.65) and multivariate analysis (HR 2.34, 2.28 to 2.40). Patients with SPMs of nasopharyngeal carcinoma (NPC) had the highest cure rate at 39%, where as esophageal and lung cancer had the worst prognosis, with a cure rate of 11%. Conclusions A worse prognosis was found for second primary cancer such as esophageal or lung cancer. Patients and healthcare providers must strongly consider and have a high clinical suspicion of these SPMs.

Epigallocatechin gallate sensitizes CAL-27 human oral squamous cell carcinoma cells to the anti-metastatic effects of gefitinib (Iressa) via synergistic suppression of epidermal growth factor receptor and matrix metalloproteinase-2. Oncol Rep 2012; 28:1799-807.

Abstract
Human head and neck squamous cell carcinoma (HNSCC) is a major cause of cancer-related death during the last decade due to its related metastasis and poor treatment outcomes. Gefitinib (Iressa), a tyrosine kinase inhibitor has been reported to reduce the metastatic abilities of oral cancer. Previous studies have shown that epigallocatechin gallate (EGCG), a green tea polyphenol, possesses cancer chemopreventive and anticancer activity. However, the mechanisms involved in the suppression of invasion and metastasis of human oral cancer cells following co-incubation with gefitinib and EGCG remain poorly understood. In the present study, we attempted to investigate the synergistic effects of a combined treatment of gefitinib and EGCG in CAL-27 cells in vitro and to elucidate the underlying molecular mechanisms associated with the supression of cell migration and invasion. In the present study, we found that the individual treatments or the combined treatment of gefitinib and EGCG synergistically inhibited the invasion and migration of CAL-27 cells using Transwell invasion and wound-healing scratch assays, respectively. Similarly, gefitinib in combination with EGCG synergistically attenuated enzymatic activity and the protein expression of MMP-2 in CAL-27 cells. Furthermore, individual or combined treatment with EGCG and gefitinib suppressed the protein expression of p-EGFR and the phosphorylated protein levels of ERK, JNK, p38 and AKT and displayed inhibitory effects on metastatic ability of CAL-27 cells. Combined effects of EGCG and gefitinib-altered anti-metastatic actions for related gene expression were observed using DNA microarray analysis. Importantly, EGCG sensitizes CAL-27 cells to gefitinib-suppressed phosphorylation of epidermal growth factor receptor (EGFR in vitro. Taken together, our results suggest that the synergistic suppression of the metastatic ability of CAL-27 cells after EGCG and gefitinib individual or combined treatment are mediated through mitogen-activated protein kinase (MAPK) signaling. Our novel findings provide potential insights into the mechanism involved with synergistic responses of gefitinib and EGCG against the progression of oral cancer.
