Abstract
Gastroesophageal reflux disease (GERD) has been hypothesized as a risk factor for development of laryngeal cancer. A case-control study was performed to assess the association of laryngeal neoplasia with GERD. Cases consisted of patients with a history of laryngeal cancer or carcinoma in situ. Controls were patients without neoplasia who matched cases 2:1 on age, sex, race, and smoking history. Univariate and multivariate analyses were performed to assess risk of laryngeal neoplasia and GERD. In total, 2094 patients were included. Cases had higher rates of GERD. Univariate analysis demonstrated a positive association between GERD and laryngeal neoplasia (odds ratio, 1.33; 95% CI, 1.07-1.64). Multivariate analysis controlling for alcohol use history also demonstrated a positive association between GERD and laryngeal neoplasia (adjusted odds ratio, 1.29; 95% CI, 1.04-1.59). These results suggest increased odds of laryngeal carcinoma and carcinoma in situ in patients with GERD when controlling for smoking and drinking history.

Gastroesophageal and Laryngopharyngeal Reflux Associated With Laryngeal Malignancy: A Systematic Review and Meta-analysis. Clin Gastroenterol Hepatol 2019; 17:1253-1264.e5. [PMID: 30366155 DOI: 10.1016/j.cgh.2018.10.028] [Citation(s) in RCA: 41] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2018] [Revised: 10/04/2018] [Accepted: 10/08/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Gastric reflux may lead to chronic mucosal inflammation and contribute to development of laryngeal malignancies, although there is controversy over this association. We performed a systematic review and meta-analysis to assess this relationship and determine the risk of laryngeal malignancy in patients with reflux disease. METHODS We performed a systematic review and meta-analysis, searching MEDLINE, EMBASE, and Web of Science databases from 1900 through April 9, 2018, for observational studies of adults reporting associations between gastroesophageal reflux disease (GERD) and/or laryngopharyngeal reflux and the risk of having or developing laryngeal malignancies. An itemized assessment of the risk of bias was conducted for each study that met inclusion criteria. The meta-analysis was performed using the Mantel-Haenszel method with random effects to account for heterogeneity. We performed subgroup analyses to determine the effect of reflux type, study design, diagnostic method, and confounding variables on the overall risk. RESULTS Of the 957 studies that were identified during systematic review, 18 case-control studies met the criteria for analysis. Our meta-analysis showed that reflux disease significantly increased the risk of laryngeal malignancy (odds ratio, 2.47; 95% CI, 1.90-3.21; P < .00001; I2 = 94%). This association remained when controlling for patient smoking and drinking (odds ratio, 2.07; 95% CI, 1.26-3.41). There was no statistically significant difference in risk of laryngeal malignancies between patients with GERD vs laryngopharyngeal reflux (P = .44). CONCLUSIONS In a systematic review and meta-analysis, we found a significant association between reflux disease and the presence of laryngeal malignancy. Prospective studies should be performed to examine this relationship.

Abstract
OBJECTIVES/HYPOTHESIS Laryngeal squamous cell carcinoma (SCC) is strongly associated with tobacco smoking. With the rising awareness of tobacco's adverse health effects, we have witnessed a global decrease in tobacco use. Nevertheless, laryngeal SCC remains prevalent and includes a subset of patients lacking the traditional risk factors. STUDY DESIGN A two-center retrospective cohort. METHODS Medical records of patients diagnosed with laryngeal SCC between 2009 and 2016 were reviewed. Data collected included demographics, smoking status, and tumor site. Patients who have never smoked were designated as nonsmokers. RESULTS The study included 330 patients with laryngeal SCC, of whom 75 (22.7%) were nonsmokers; this rate was relatively similar for each of the two institutions independently (21.9% and 25%). There were 285 patients with glottic SCC and 45 with supraglottic SCC. All nonsmoking patients in this cohort had glottic SCC, representing 26.3% (75/285) of the glottic SCC cases. The rate of female patients was significantly higher among nonsmokers. Of the patients with glottic SCC, females represented 25.3% (19/75) of the nonsmokers compared with 12.4% (26/210) of the smokers (P = .008). Mean age at diagnosis was 60.2 ± 17.5 years for nonsmoking glottic SCC patients and 63.6 ± 12.4 years for smokers (P = .280). However, nonsmokers demonstrated a distinct age distribution pattern. Nonsmoking females with glottic SCC demonstrated a bimodal age distribution pattern; 73.7% (14/19) were age <40 years or >75 years at diagnosis. CONCLUSIONS The rate of laryngeal SCC in nonsmokers is higher than what has previously been reported, representing a growing proportion, and may suggest a shift in etiology. Knowing that laryngeal SCC in nonsmokers predominantly affects the glottis, and that females and age extremities are more vulnerable, the traditional screening paradigm should be revised. LEVEL OF EVIDENCE 4 Laryngoscope, 130:E108-E115, 2020.

Abstract
Aims and background To determine the role of reflux esophagitis in the development of pharyngolaryngeal squamous cell carcinoma in non-smoking and non-drinking patients. Methods The study population consisted of 92 consecutive non-smoking and non-drinking patients with histologically confirmed squamous cell carcinoma of the pharynx and the larynx. As a control, a group of 125 lifetime non-smoking and non-drinking cancer-free subjects was selected. Results Patients with pharyngolaryngeal cancer had a higher prevalence of reflux esophagitis than the control subjects (P <0.0001). Conclusions Our results confirm that reflux esophagitis in itself is associated with an increased risk of upper aerodigestive tract cancer.

Abstract
PURPOSE Investigate the incidence, the degree and the effect of gastro-pharyngeal reflux (GPR) in laryngectomised patients. MATERIALS AND METHODS Behavioral and 24-hour pH- and impedance-monitoring data were prospectively analyzed for 25 laryngectomised patients with no previous history of GER in outpateints' setting. Reflux detected was characterized as either acid, weakly acidic or nonacid. Proximal reflux was found at 15cm above the LES. RESULTS 40% of patients presented a pathological number of reflux episodes in the upright position (p<0.0001); 9 of them presented a pathologic bolus exposure time. Bolus exposure at the proximal sphincter was one fourth-fold lower than 5cm above the LES (p=0.3593). There was a prevalence of acid reflux at both sphincters (p<0.0001); liquid reflux was prevalent at the LES (p=0.003) and mixed reflux at the UES (p=0.0001). Median REs was higher than time acid exposure (p=0.0013). CONCLUSIONS Pre- and post-surgical reflux investigation could identify preexisting reflux severity and screen potential high-risk cancer patients for postoperative complications. This might allow the early onset of acid suppressive therapy in presence of pathologic findings in high-complication risk cancer patients.

Abstract
Objective To describe the anatomic location and distribution of glottic dysplasia and early glottic cancer. Study Design Case series with chart review. Setting Tertiary care referral center. Subjects and Methods Review of 167 glottic dysplasia or carcinoma patients between 2008 and 2013. Lesions were described in terms of location and size, and a novel grid system was used to map out anatomic distribution. Results Seventy-eight patients with dysplasia and 89 with early glottic carcinoma were included. One hundred twenty-eight were smokers and 39 nonsmokers. The medial aspect of the vocal fold was more involved than the superior aspect, 95% versus 71%, respectively ( P < .001). The superior aspect was more involved in smokers, 77% versus 51% in nonsmokers ( P = .0016). Using a grid system, the most involved area was the midpoint of the membranous vocal fold at the transition between the superior and medial aspects. Ninety-seven percent of the lesions occupied this specific area, with no difference between smokers and nonsmokers. The vocal process mucosa was involved in 48 patients. Exclusive vocal process involvement was limited to 2 cases. All other 46 patients demonstrated extensive disease, encompassing more than half of the vocal fold’s length. Carcinomatous lesions tended to be larger relative to dysplastic lesions. Otherwise, all lesion types showed a similar pattern of distribution. Conclusions Premalignant and malignant glottic lesions tend to involve the medial aspect of the vocal fold and the midpoint of the membranous part in particular. In smokers, lesions tend to be larger on presentation and are more likely to involve the superior aspect.

Abstract
Gastroesophageal reflux disease (GERD), or its variation known as laryngopharyngeal reflux (LPR), has been recognized as a potential cause of several laryngeal disorders. Patients with laryngeal cancer have lifestyle risk factors, especially tobacco and alcohol consumption, that play an etiological role in the development of their cancer but also places them at risk for reflux. The question then arises whether there is merely an association or a causal relationship between laryngeal cancer and reflux. However, despite a number of studies, a causal relationship with laryngeal cancer is uncertain. In this article, we address the current literature in a critical manner to evaluate the relationship between reflux and laryngeal cancer. From the review of the literature, we conclude that there is insufficient evidence to support a causal role of reflux in laryngeal cancer, mainly because of the confounding effect of tobacco and alcohol consumption and the inaccuracies in the diagnosis of reflux.

Abstract
BACKGROUND Gastric reflux can reach into the upper airway, inducing cellular damage in the epithelial lining. This condition is believed to be a risk factor for development of laryngopharyngeal squamous cell carcinoma (LPSCC), although the literature is conflicting. METHODS To better clarify this relationship, we assessed the association of self-reported heartburn history and medication use among 631 patients with LPSCCs and 1234 control subjects (frequency-matched on age, gender, and town of residence) enrolled as part of a population-based case-control study of head and neck squamous cell carcinoma in the greater Boston area. RESULTS After adjusting for age, gender, race, smoking, alcohol consumption, HPV16 seropositivity, education, and body mass index, subjects reporting a history of frequent heartburn and who were neither a heavy smoker nor heavy drinker had a significantly elevated risk of LPSCCs [OR, 1.78; 95% confidence interval (CI), 1.00-3.16]. Among those with a history of heartburn, there was an inverse association between antacid use and LPSCCs relative to those never taking heartburn medication (OR, 0.59; 95% CI, 0.38-0.93) that remained consistent when analyzed by smoking/drinking status, HPV16 status, or by primary tumor site. CONCLUSIONS Our data show that gastric reflux is an independent risk factor for squamous cancers of the pharynx and larynx. Further studies are needed to clarify the possible chemopreventive role of antacid use for patients with gastric reflux. IMPACT Elucidation of additional risk factors for head and neck cancer can allow for risk stratification and inform surveillance of high-risk patients.

Abstract
Head and neck cancer accounts for an estimated 47,560 new cases and 11,480 deaths annually in the United States, the majority of which are squamous cell carcinomas (HNSCC). The overall 5 year survival is approximately 60% and declines with increasing stage at diagnosis, indicating a need for non-invasive tests that facilitate the detection of early disease. DNA methylation is a stable epigenetic modification that is amenable to measurement and readily available in peripheral blood. We used a semi-supervised recursively partitioned mixture model (SS-RPMM) approach to identify novel blood DNA methylation markers of HNSCC using genome-wide methylation array data for peripheral blood samples from 92 HNSCC cases and 92 cancer-free control subjects. To assess the performance of the resultant markers, we constructed receiver operating characteristic (ROC) curves and calculated the corresponding area under the curve (AUC). Cases and controls were best differentiated by a methylation profile of six CpG loci (associated with FGD4, SERPINF1, WDR39, IL27, HYAL2 and PLEKHA6), with an AUC of 0.73 (95% CI: 0.62-0.82). After adjustment for subject age, gender, smoking, alcohol consumption and HPV16 serostatus, the AUC increased to 0.85 (95% CI: 0.76-0.92). We have identified a novel blood-based methylation profile that is indicative of HNSCC with a high degree of accuracy. This profile demonstrates the potential of DNA methylation measured in blood for development of non-invasive applications for detection of head and neck cancer.

Abstract
OBJECTIVE/HYPOTHESIS Laryngopharyngeal reflux (LPR) is thought to be a significant risk factor for laryngeal squamous cell carcinoma (SCC), but causality has never been proven. It is accepted that chronic reflux into the esophagus can induce metaplastic changes in esophageal mucosa with subsequent increased risk of esophageal adenocarcinoma, but no similar associations have been established for LPR and laryngopharyngeal SCC. The objective of this study was to test the hypothesis that reflux of pepsin into the laryngopharynx can promote carcinogenesis. STUDY DESIGN Translational research study. METHODS Normal human laryngeal primary epithelial cell cultures and hypopharyngeal FaDu SCC cells were exposed to human pepsin and analyzed by Human Cancer PathwayFinder and miRNA Superarrays, flow cytometry, and Western blot to determine the effect of pepsin on carcinogenesis. Laryngeal biopsy specimens taken from cancer patients and normal control subjects were analyzed for the presence of pepsin by Western blot. RESULTS Microarray analysis demonstrated that pepsin significantly altered the expression of 27 genes implicated in carcinogenesis and also affected the expression of 22 microRNAs known to be altered in human head and neck cancers. Pepsin increased proliferation in both FaDu SCC cells and cultured normal laryngeal epithelial primary cells by increasing S phase distribution on flow cytometry analysis in a time- and dose-dependent manner. Furthermore, pepsin was detected in 60% (3/5) human laryngeal cancer biopsies, absent in all (0/5) normal control specimens. CONCLUSIONS These data support a role for refluxed pepsin in the promotion of epithelial proliferation and carcinogenesis of the larynx and pharynx.

Abstract
PURPOSE The aim of the study was to survey the association between prevalence of acid-related inflammation in the upper digestive tract and laryngeal cancer. MATERIALS AND METHODS A case-control study was done in an otolaryngology ward at an academic university. Totally, 65 patients with laryngeal cancer and 65 cancer-free matched controls underwent esophagogastroduodenoscopy, and endoscopic findings were collected. RESULTS In the case group, positive endoscopic findings were significantly higher than the control group (87.7% vs 58.5%; P < .001). Laryngeal cancer patients had erosive esophagitis, and gastritis ± other findings more than the control group (48 vs 29 cases) and the difference was statistically significant. CONCLUSION The difference between endoscopic findings in cases and controls was statistically significant. Severe inflammation and erosion existed in patients with laryngeal cancer that could be due to increased acid secretion. Our study supported the hypothesis that gastric acid and pepsin play a role in laryngeal cancer.

Abstract
Objectives: Tracheoesophageal puncture (TEP) and prosthesis insertion is a well-established method of voice rehabilitation after laryngectomy. Maintenance of the prosthesis and tract can be challenging, and reflux to the TEP site has been proposed as a cause. The sites of TEP were evaluated for the presence of pepsin in tissue biopsy specimens and tract secretions to explore this association. Methods: Patients with TEP were interviewed for a history of symptoms related to reflux, medication use history, TEP voice quality, and incidence of TEP complications. Tissue biopsy specimens and tract secretions were obtained from TEP sites and analyzed for the presence of pepsin via sodium dodecyl sulfate–polyacrylamide gel electrophoresis Western blot analysis. Results: Twelve of 17 patients (47%) had some history of preoperative or postoperative symptoms of gastroesophageal reflux disease or laryngopharyngeal reflux. Pepsin was present within the TEP site in a total of 10 of 17 patients (58%; 7 of 17 tissue biopsy specimens and 6 of 7 secretion samples). There were no statistically significant associations between the presence of pepsin and sex, reflux history, use of acid suppressive medicine, or time since laryngectomy. Conclusions: Reflux with subsequent pepsin deposition into the TEP tract occurs in a majority of laryngectomy patients. Further studies on the effect of reflux on the health and function of the TEP tract are warranted.

Abstract
To determine if socio-economic status (SES) affects the stage at presentation of head and neck cancer (HNC) patients in Ottawa, Canada. To determine if the method of diagnosis affects the stage at presentation in these patients. We obtained data on SES, method of diagnosis, and stage at presentation for patients presenting to the head and neck cancer clinic at The Ottawa Hospital Regional Cancer Centre (TORCC). We performed a logistic regression analysis using stage at presentation as the dependent variable. We found no statistically significant association between average family income (by postal code) and stage at presentation. We found that oral cancers presented at a later stage compared with other HNCs but that who made the diagnosis was an important factor. Oral cancers diagnosed by a dentist had 3.44 times the odds of being at a later stage than other HNCs (CI 1.01-11.96), but oral cancers diagnosed by other means had 11.42 times the odds of being at a later stage than other HNCs. We found that male patients presented at a later stage than female patients (OR 2.62, CI 1.03-6.63). Finally, former smokers had about 1/3 the odds of presenting at a later stage than current smokers (OR 0.33, CI 0.13-0.84) although nonsmokers were not significantly less likely than current smokers to present later (OR 0.47, CI 0.17-1.32). We found no evidence that in Ottawa, Canada patients of a lower SES with HNC presented at an different stage than patients with higher SES. We found that patients presenting with oral cancers presented at an earlier stage if they were diagnosed by a dentist.

Abstract
BACKGROUND Examination of the laryngopharyngeal area is not always performed during routine upper gastrointestinal (UGI) endoscopy although initial studies reported pathological findings in 0.9-3.5% of cases. The aim of this study was to prospectively evaluate the accuracy of screening the laryngopharyngeal area during routine UGI endoscopy, before insertion of endoscope into the oesophagus, to avoid a misinterpretation of trauma-related hyperaemia or erythema as signs of laryngitis. METHODS The study included 1297 patients undergoing elective UGI endoscopy, asymptomatic in the laryngopharyngeal area, who underwent a carefully structured examination of the laryngopharyngeal area, videotaped for later blinded review. If pathological findings were suspected, patients were referred to otorhinolaryngologists for additional evaluation. In all cases the DVDs were reviewed by two ear, nose, and throat (ENT) specialists blinded to the endoscopic findings. RESULTS In 1130 (87.12%) patients the examination was performed successfully before insertion of the endoscope into the oesophagus. Gastro-oesophageal reflux disease (GORD) symptoms were present in 254 (22.5%) patients, and erosive oesophagitis was documented in 89 (7.9%) patients. In 44 (3.89%) patients the pathology was suspected by the endoscopist and confirmed by the otorhinolaryngologists. Moreover, 8 (0.71%) patients were found to have laryngeal pathology in the DVDs reviewed by the ENT specialists, further confirmed by laryngoscopy. Sensitivity, specificity, positive, and negative predictive values were 84.61%, 100%, 100%, and 99.26%, respectively, for detecting laryngeal abnormalities by the endoscopist. The most important findings were leukoplakia (n=4), posterior laryngitis (n=16), Reinke's oedema (n=2), and hyperkeratosis of arytenoid folds (n=2). A strict correlation emerged between GORD and posterior laryngitis (75%) and between GORD and Reinke's oedema (100%), documented by pHmetry. A significant association was also observed between heavy smoking and leukoplakia (75%), and hypertrophy of pharyngeal tonsils (100%), respectively. All other findings were lesions without clinical significance. CONCLUSIONS Screening examination of the laryngopharyngeal area should be part of each UGI endoscopy revealing important laryngeal pathology.

Abstract
Currently, there is no Italian version of the Reflux Symptom Index (RSI). The aim of this study was to develop an Italian RSI and to evaluate its internal consistency, reliability, and clinical validity. The study design used was a cross-sectional survey study. Eighty patients with a Reflux Finding Score (RFS) >7, and 193 asymptomatic subjects were included in the study. For the RSI reliability analysis, the appositely developed Italian RSI was filled twice, with a week interval, by the 80 patients and 80 control subjects. The test-retest reliability was assessed through the Pearson correlation test, whereas the Cronbach's alpha coefficient was used for internal consistency analysis. For the clinical validity assessment, the scores obtained in the pathological group were compared with the data from the asymptomatic individuals through the Student's t test. Finally, the correlation between RSI and RFS in the 80 patients was assessed. All of the patients filled in the entire questionnaire autonomously. The test-retest reliability in the patients, as well as in the control group, was very high (r>0.90); the internal consistency also showed very high values (alpha=0.99). The mean RSI score in the patients was 21.1+/-6.6, whereas in the control group it was 6.3+/-5.6; the difference was statistically significant (P=0.0001). The mean RFS score in the 80 patients was 9.2+/-2.7 and the correlation between RFS score and RSI score was rather high (r=0.89). The Italian RSI is easily administered, highly reproducible, and exhibits excellent clinical validity.

Abstract
Objectives: We sought to document the mucin gene profile in normal human laryngeal epithelium and compare it with that in patients with reflux-attributed laryngeal injury or disease. We also investigated the effect of low pH with or without pepsin on mucin messenger RNA levels in vitro. Methods: Laryngeal biopsy specimens were obtained from 3 patients with clinically diagnosed laryngopharyngeal reflux and from 2 control subjects who had no signs or symptoms of reflux. Signs and symptoms were assessed by the Reflux Finding Score and the Reflux Symptom Index, respectively. Reverse transcription–polymerase chain reaction (RT-PCR) was performed to establish the mucin gene profile. Human hypopharyngeal epithelial cells were exposed to pH 7, 5, 4, and 2 with and without pepsin (0.1 mg/mL) for 20 minutes at 37°C, and expression of selected mucins was analyzed via real-time RT-PCR. Results: Mucin 1–5, 7, 9, 13, 15, 16, and 18–20 transcripts were detected in normal laryngeal epithelium, whereas mucin 6, 8, and 17 transcripts were not. Mucins 2, 3, and 5 were expressed at reduced levels in patients with reflux-attributed laryngeal injury or disease. These mucin genes were up-regulated after exposure to low pH in vitro (p < 0.005). Pepsin inhibited this up-regulation (p < 0.001). Conclusions: Reflux laryngitis is associated with down-regulation of mucin gene expression.

Abstract
PURPOSE: To investigate the carcinogenic action of hydrochloric acid, pepsin and sodium nitrate on the oropharyngeal mucosa of rats, simulating the reflux of gastric contents. METHODS: Eighty-two Wistar rats were divided in seven groups and submitted to 2 or 3 weekly applications of hydrochloric acid, pepsin and sodium nitrate on the pharyngeal mucosa during six months. Study groups comprised 12 animals each. Rats in groups I and II were submitted to 2 (GI) or 3 (GII) weekly applications of 0.1N hydrochloric acid. Groups III and IV were submitted to 2 (GIII) or 3 (GIV) weekly applications of 0.1N hydrochloric acid solution with pepsin. Groups V and VI were submitted to 2 (GV) or 3 (GVI) weekly applications of 0.1N hydrochloric acid and treated with daily nitrate diluted in water. Group VII consisted of 10 animals submitted to 2 weekly applications of filtered water. RESULTS: No dysplasia, intra-epithelial neoplasia or invasive carcinomas were detected. Inflammatory changes were observed in varying degrees and mast cells were more common in Groups V and VI (p=0.006). CONCLUSION: The data of the current study could not corroborate the hypothesis that gastroesophageal and pharyngolaryngeal refluxes are carcinogenic factors to the laryngopharyngeal mucosa, and more studies are necessary in the future.

Abstract
PURPOSE OF REVIEW The present paper examines the recent literature on extra-esophageal reflux and discusses how it affects patient testing and treatment of upper respiratory track inflammatory disease. RECENT FINDINGS Assays for pepsin have been developed casting more insight into the pathophysiology of extra-esophageal reflux as well as looking at the role of protective factors in upper respiratory mucosa. Similarities and differences in esophageal and extra-esophageal reflux continue to be explored. Acid suppression in extra-esophageal reflux improves symptoms before physical findings, but some patients do not respond. Mildly acidic (pH > 4) and alkaline reflux are being examined more in extra-esophageal reflux with impedance testing playing a more prominent role. Recent studies have also focused on whether extra-esophageal reflux could affect tissues of the nasopharynx, sinuses, or middle ear. Caution has been issued as acid suppressive therapies have been associated with hip fracture in older patients. SUMMARY Symptoms caused by reflux may reflect underlying weaknesses in mucosal resilience to acid and pepsin in addition to the variations in exposure to gastric contents. In some patients mildly acidic or alkaline reflux may be important and gastric contents may reach the nasopharynx or middle ear. Carefully designed placebo-controlled trials are needed.

Abstract
BACKGROUND Despite increasing clinical and experimental evidence of its existence, otolaryngological manifestations of reflux disease remain controversial, concerning diagnosis as well as treatment. AIM Proper understanding of laryngopharyngeal reflux disease (LPRD). METHOD Review of literature. RESULTS Scepticism concerning LPRD is based upon differences between gastro-oesophageal reflux disease and LPRD; lack of specificity and sensitivity of diagnostic tests to confirm LPRD; non-specificity of laryngological symptoms, which are difficult to distinguish from other causes of upper respiratory tract inflammation; non-specificity of laryngological signs in laryngoscopy, with high intra- and inter-observer variability in evaluation; diagnosis of LPRD is essentially only based on a combination of diagnostic signs and symptoms, which cannot be attributed to other pathology; slow, or sometimes lack of, response of LPRD symptoms to proton pump inhibitor (PPI) medication and lack of evidence concerning efficacy of PPIs in placebo-controlled trials. CONCLUSIONS LPRD remains a diagnosis by exclusion and resolution of symptoms following 4-month trial of 40 mg PPI twice daily is, for all practical purposes, considered proof of the initial diagnosis. However, non-response does not exclude LPRD as PPIs have no influence on noxious non-acid components of the refluxate.

Abstract
OBJECTIVES Extraesophageal reflux disease (EERD) is linked with serious and varied health concerns. The authors' goal was to determine the prevalence of EERD and the effect on health-related quality of life in adults within a large community-based sample. STUDY DESIGN Survey study conducted in a community setting. METHODS In the Madison, Wisconsin area, 1845 adult subjects were surveyed. Main outcome measures were frequently of GERD and laryngeal symptoms, the Medical Outcomes Trust Short Form 12 (SF-12), Voice Handicap Index (VHI), and Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaires. RESULTS More than 66% of subjects reported either GERD or laryngeal symptoms, and 26% reported both GERD and laryngeal symptoms (which reflect symptoms commonly reported for EERD). In addition, 39% of our sample took medicine for heartburn. Forty-four percent of subjects with both GERD and laryngeal symptoms reported occasional breathing difficulties, and 38% of these subjects reported a voice disorder. Significant reductions in perceived quality of general health, digestive health, and voice-related quality of life were found in subjects with both GERD and laryngeal symptoms, in comparison with subjects manifesting each symptom group alone, or in subjects with no symptoms. CONCLUSIONS The presence of GERD and laryngeal symptoms, and their concurrence, was identified in a substantial number of subjects. The GERD and laryngeal symptoms surveyed represent those most commonly reported for EERD. Because EERD has been linked with tissue damage and reductions in health-related quality of life, it is important to identify these persons and provide treatment before progression of the condition.

Abstract
OBJECTIVE To recognize specific clinicopathological characteristics of non-smoking and non-drinking (NSND) head and neck squamous cell carcinoma (HNSCC) patients. This can increase our knowledge regarding a potentially different carcinogenesis in these patients. STUDY DESIGN/METHODS Retrospective analysis of data for 195 NSND patients with HNSCC and comparison with data for patients with HNSCC obtained from the Netherlands Cancer Registry. RESULTS Compared with all HNSCC patients in the Netherlands, our NSND patients with HNSCC were typically female (n = 142; 73%vs 26%), old at disease presentation (mean 73 years vs 64 years), and had tumors mainly of the oral cavity (n = 130; 66%vs 25%). Most tumors were stage I (n = 67; 34%) and stage IVA (n = 59; 30%). The incidence of second primary tumors (SPTs) was high (n = 32; 16%), mainly occurring in the oral cavity (n = 26; 13%). DISCUSSION/CONCLUSION Our study confirms that NSND HNSCC patients have different clinicopathological characteristics from those of the overall HNSCC population; however, the frequency of SPTs is as high in NSND patients as in patients who smoke and drink alcohol. More research, and particularly molecular data are needed to obtain a better understanding of head and neck cancer in NSND patients.

Abstract
PURPOSE Gastroesophageal reflux disease (GERD) is common in patients with laryngeal cancer. However, the role of GERD in laryngeal cancer remains controversial because of poor matching and selection of inappropriate control groups in prior studies. We aimed to better understand this relationship by conducting a matched case-control study. METHODS This study was based in a single tertiary care center over a 2-year period. Cases included all patients with a diagnosis of new laryngeal cancer presenting to the otolaryngology clinics. Two controls, derived from the internal medicine clinics, were matched to the cases on an individual basis for age (within 1 year), gender, ethnicity, and time of first visit to the institution (within 1 month). Data were extracted by chart review. Conditional logistic regression was used to assess the relationship between laryngeal cancer and GERD, tobacco, and alcohol consumption. RESULTS A total of 96 cases were matched to 192 controls. On univariable analysis, the significant risk factors were current smoking, odds ratio (OR) 5.46 (95% confidence interval [CI], 2.59-11.50); alcohol, OR 1.97 (CI, 1.19-3.26); and GERD, OR 1.79 (CI, 1.03-3.11). On multivariable analysis, only smoking and GERD continued to be significantly associated with laryngeal cancer, OR 6.08 (CI, 2.82-13.10) and OR 2.11 (CI, 1.16-3.85), respectively. CONCLUSIONS Smoking and GERD are significant risk factors for laryngeal cancer and may have an independent incremental risk for laryngeal carcinogenesis.

Abstract
Gastroesophageal reflux disease has been implicated as a causative factor in several laryngeal disorders. Its involvement in laryngeal cancer is of interest not only from a clinicopathologic aspect, but also from a public health perspective. However, despite a number of studies, a causal relationship with laryngeal cancer is uncertain. In this article, we address the current literature in a critical manner to facilitate the understanding of this subject and evaluate the relationship between gastroesophageal reflux disease and laryngeal carcinoma.

Abstract
Gastroesophageal reflux disease (GERD) has been increasingly associated with ear, nose, and throat (ENT) signs and symptoms. This condition, often referred to as laryngopharyngeal reflux (LPR) has become increasingly prevalent. However, the cause and effect relationship between GERD and laryngeal signs or symptoms is far from established. Many patients diagnosed initially with GERD as the cause of laryngeal signs do not symptomatically or laryngoscopically respond to aggressive acid suppression and do not have abnormal esophageal acid exposure by pH monitoring. This has resulted in frustration on the part of both gastroenterologists and ENT physicians and confusion on the part of patients. The current recommendations for the management of LPR patients call for initial empiric therapy with twice daily proton-pump inhibitors (PPIs) for 2 to 4 months. In those unresponsive to such therapy, diagnostic testing with prolonged pH monitoring may be indicated. However, in the majority of such patients, the reason for lack of response to PPI therapy may be irritation of the larynx by causes other than GERD. Surgical fundoplication in this group of patients has lower efficacy than in those with typical symptoms of GERD and is reserved for those with improvement on acid-suppressive therapy.

Abstract
OBJECTIVES The objectives of this study were to define the conditions that give rise to a stress protein response in laryngeal epithelium and to investigate whether and how stress protein dysfunction contributes to reflux-related laryngeal disease. METHODS Western analysis was used to measure stress protein (squamous epithelial proteins Sep70 and Sep53 and heat shock protein Hsp70) and pepsin levels in esophageal and laryngeal tissue specimens taken from both normal control subjects and patients with pH-documented laryngopharyngeal reflux (LPR) who had documented lesions, some of whom had laryngeal cancer. A porcine organ culture model was used to examine the effects of low pH and pepsin (0.1% porcine pepsin A) on stress protein levels. A laryngeal squamous carcinoma (FaDu) cell line was used to examine uptake of human pepsin 3b-tetramethyl-5 and -6 isothiocyanate. RESULTS Sep70, Sep53, and Hsp70 were found to be expressed at high levels, and pepsin was not detected, in esophageal and laryngeal specimens taken from normal control subjects and in esophageal specimens taken from LPR patients. The patients with LPR were found to have significantly less laryngeal Sep70 (p = .027) and marginally less laryngeal Sep53 (p = .056) than the normal control subjects. Laryngeal Hsp70 was expressed at high levels in the LPR patients. The patients with laryngeal cancer had significantly lower levels of Sep70, Sep53 (p < .01), and Hsp70 (p < .05) than the normal control subjects. A significant association was found between the presence of pepsin in laryngeal epithelium from LPR patients and depletion of laryngeal Sep70 (p < .001). Using the organ culture model, we demonstrated that laryngeal Sep70 and Sep53 proteins are induced after exposure to low pH. However, in the presence of pepsin, Sep70 and Sep53 levels are depleted. Confocal microscopy analysis of cultured cells exposed to labeled pepsin revealed that uptake is by receptor-mediated endocytosis. CONCLUSIONS These findings suggest that receptor-mediated uptake of pepsin by laryngeal epithelial cells, as may occur in LPR, causes a change in the normal acid-mediated stress protein response. This altered stress protein response may lead to cellular injury and thus play a role in the development of disease.

Abstract
Laryngopharyngeal reflux (LPR) as a causative irritating factor in the development of laryngeal carcinoma has been suggested. However, the association between LPR and laryngeal carcinoma remains unclear. The aim of this study was to compare the prevalence and severity of reflux between patients with laryngeal carcinoma and clinical LPR. The intention was to find out if a correlation exists between the laryngeal findings and the level of acid reflux. The study population consisted of 29 patients with laryngeal cancer (group I), 33 LPR patients with normal laryngeal findings (group II) and 70 LPR patients with related laryngeal pathology (group III). The results of 24-h, double-channel ambulatory esophageal pH monitoring were analyzed comparing the three groups. The occurrence and severity of abnormal acid reflux at the upper and lower esophageal segments were evaluated. The incidence of LPR or gastroesophageal reflux (GER) did not vary in any of the three groups (LPR was present in 62, 42 and 56% of the patients, while GER was present in 45, 24 and 37% of the patients, respectively). Patients with LPR or GER from the three groups did not differ significantly in terms of the number of acid reflux episodes and percentage of times when the pH was <4. Our data do not support the hypothesis that LPR can be an independent risk factor in the development of larynx cancers. However, the data also do not thoroughly exclude the possibility. The reason why LPR leads to variable pathologies in the larynx may be uncovered by studies probing the differences between patients via detailed examinations of the local anti-reflux barriers such as epithelial morphology and functions.

Abstract
PURPOSE To examine the proposed relation between gastroesophageal reflux disease and cancers of the larynx and pharynx. EXPERIMENTAL DESIGN A cohort of 66,965 patients with discharge diagnoses of heartburn, hiatal hernia, or esophagitis was identified in the Swedish Inpatient Register. We observed a total of 376,622 person-years in the cohort. Identification of laryngeal and pharyngeal cancers was achieved through the Swedish Cancer Register. Standardized incidence ratios, the ratio of the observed to the expected number of cancers, derived from the general Swedish population and adjusted for sex, age, and calendar year, was used to estimate the relative risk. RESULTS During follow-up, 30 cases of laryngeal and 31 cases of pharyngeal cancer were detected in the cohort. Slightly increased risks of laryngeal [relative risk, 1.6; 95% confidence interval (CI), 1.1-2.2] and pharyngeal carcinomas (relative risk, 1.9; 95% CI, 1.3-2.8) were observed in the total reflux cohort. After stratification to exclude cohort members with a diagnosis of alcoholism, no significant increase in the risk of laryngeal (relative risk, 1.3; 95% CI, 0.8-2.0) or pharyngeal carcinomas (relative risk, 1.0; 95% CI, 0.5-1.6) was found compared with the general population. Furthermore, there were no dose-response patterns of the risk for laryngeal and pharyngeal cancers with years of cohort follow-up, indicators of reflux severity, or specificity of reflux diagnosis. CONCLUSION This study provides no evidence in support of the proposed association between gastroesophageal reflux disease and cancers of the larynx or pharynx.

Abstract
OBJECTIVE/HYPOTHESIS The significance of gastroesophageal reflux disease (GERD) in laryngeal cancer is controversial due to disparate studies. To evaluate the overall strength of the association of GERD with laryngeal cancer, we performed meta-analysis of the original studies in literature. STUDY DESIGN Meta-analysis. METHODS All studies cited on Ovid Medline (1966-June 2004), EMBASE (1980-June 2004), and Cochrane database describing GERD and laryngeal cancer were eligible for inclusion. The inclusion criteria for the study included original controlled study design and a clear documentation of the reflux prevalence in cases and controls. Statistical analysis was performed by NCSS software. RESULTS Fifteen original studies were identified. Eight studies did not have control groups, two studies did not clearly document GERD prevalence in controls, and two studies were published using the same data, one of which was included in this meta-analysis. Thus, four studies qualified for inclusion for the meta-analysis. The methodologic quality in the studies was heterogeneous, not only in the evaluation of confounding risk factors such as smoking and alcohol but also in the mode of GERD diagnosis. There was also significant heterogeneity of effect of reflux among the studies (P = .001). The pooled odds ratio on the basis of fixed-effects model was 2.86 (95% CI, 2.73-2.99), and on the basis of random-effects model was 2.37 (95% CI 1.38-4.08). CONCLUSION Our meta-analysis suggests that GERD may be a significant risk factor for laryngeal cancer. However, given the heterogeneity of the published data, future prospective controlled studies are needed.

Abstract
Gastroesophageal reflux disease is associated with various otolaryngological disorders. The aim of this retrospective study was to determine the role of gastroesophageal reflux disease in the development of laryngeal squamous cell carcinoma (SCC) in non-smoking and non-drinking patients. The study population consisted of 36 consecutive non-smoking and non-drinking patients with histologically confirmed SCC of the larynx. As a control, a group of 125 lifetime non-smoking and non-drinking cancer-free subjects were selected. Patients with laryngeal cancer had a higher prevalence of gastroesophageal reflux disease than the control subjects (P < 0.0001). Our results confirm the fact that gastroesophageal reflux disease in itself is associated with an increased risk of laryngeal cancer.

Abstract
OBJECTIVES/HYPOTHESIS The objective was to investigate the potential use of pepsin and carbonic anhydrase isoenzyme III (CA-III) as diagnostic markers for laryngopharyngeal reflux disease. STUDY DESIGN Prospective cell biological investigation was conducted of laryngeal biopsy specimens taken from 9 patients with laryngopharyngeal reflux disease and 12 normal control subjects using antibodies specific for human pepsin (produced in the authors' laboratory within the Department of Otolaryngology at Wake Forest University Health Sciences, Winston-Salem, NC) and CA-III. METHODS Laryngeal biopsy specimens were frozen in liquid nitrogen for Western blot analysis and fixed in formalin for pepsin immunohistochemical study. Specimens between two groups (patients with laryngopharyngeal reflux disease and control subjects) were compared for the presence of pepsin. Further analyses investigated the correlation between pepsin, CA-III depletion, and pH testing data. RESULTS Analysis revealed that the level of pepsin was significantly different between the two groups (P < .001). Secondary analyses demonstrated that presence of pepsin correlated with CA-III depletion in the laryngeal vocal fold and ventricle (P < .001) and with pH testing data in individuals with laryngopharyngeal reflux disease. CONCLUSION Pepsin was detected in 8 of 9 patients with laryngopharyngeal reflux disease, but not in normal control subjects (0 of 12). The presence of pepsin was associated with CA-III depletion in the laryngeal vocal fold and ventricle. Given the correlation between laryngopharyngeal reflux disease and CA-III depletion, it is highly plausible that CA-III depletion, as a result of pepsin exposure during laryngopharyngeal reflux, predisposes laryngeal mucosa to reflux-related inflammatory damage.

Abstract
Although more common in developing countries, over 11,000 deaths will occur in the United States from head and neck cancer in 2004. Squamous cell carcinomas account for the vast majority of cases in the United States and the majority of these are related to exposure to tobacco and alcohol. Newer data suggest a genetic contribution. This group is the focus of primary and secondary preventative efforts.

Abstract
BACKGROUND AND AIMS The specific agents responsible for producing laryngeal signs and symptoms are currently unknown. We systematically evaluated the damaging role of gastric (acid and pepsin) and duodenal (bile acids and trypsin) ingredients individually and in combination on different laryngeal structures in an experimental canine model. METHODS A total of 42 beagles were studied (wt 9-15 kg each). After pentathol anesthesia all dogs underwent laryngoscopy. Injury (punch biopsy) was caused to the right vocal cord, medial arytenoid wall, and posterior cricoid wall on day 1. Pepsin (0.5 mg/ml), conjugated bile acid (CBA) (ursodeoxycholic acid, 300 micromolar), unconjugated bile acids (UBA) (cholic, 300 micromolar), trypsin (0.5 mg/ml) at pH 1-2, 4-5, and 6-7 were applied bilaterally to laryngeal sites three times per week for a total of 9-12 applications. Changes in laryngeal sites were scored visually. All dogs were sacrificed 1 day post last application. Laryngeal tissue was harvested and sent for blinded pathological examination. Histologic and visual scores were compared to each other and to control- and sham-treated dogs. RESULTS Pepsin alone (8.5 +/- 1.66) or combined with CBA (16.63 +/- 1.66) at pH 1-2 resulted in significant (p < 0.001) severe histological inflammation much greater than with other agents. Duodenal ingredients caused no or minimal degree of histological damage at all pH values. Visual scores above subtle erythema were significantly (p < 0.001) higher in the animals exposed to pepsin followed by CBA alone or in combination with pepsin at pH 1-2. There was a significant (p < 0.01) correlation between histology and visual scores (rho = 0.47; 95% CI = 0.30-0.60) for all sites combined. Of the three laryngeal sites, vocal cords were the most sensitive to injury by applied solutions. CONCLUSIONS (i) In acidic refluxate, pepsin and CBAs are the most injurious agents affecting laryngeal tissue. (ii) Duodenal agents do not play a significant role in causing laryngeal injury. (iii) Aggressive acid suppression should eliminate the injurious potential of any gastroduodenal refluxate.

Abstract
BACKGROUND Laryngopharyngeal reflux (LPR) disease arises from the effects of refluxed gastric contents on the proximal aerodigestive tract. LPR patients are often lumped into the category of "atypical" reflux. LPR symptoms are hoarseness, globus, cough, and pharyngitis. Severe disease is associated with subglottic stenosis and laryngeal cancer. Treatment includes lifestyle modifications and medications. The role of fundoplication for LPR has yet to be defined. STUDY DESIGN Forty-one patients underwent fundoplication for LPR. They were prospectively followed with three outcomes measures: The Reflux Symptom Index, a laryngoscopic grading scale (Reflux Finding Score), and a reflux-based specific quality-of-life scale. RESULTS Average early followup was at 4 months and late followup was at 14 months. The Reflux Symptom Index improved by 5.4 early (p < 0.05) and 6.5 late (p < 0.05). Improvement between early and late periods approached significance (p < 0.09). Reflux Finding Score improved 3.8 (p < 0.05) early and 4.4 (p < 0.05) late. The Quality of Life Index improved 0.6 early and 2.3 (p < 0.05) late. By Reflux Symptom Index criteria, 26 patients were improved early versus 35 late (p < 0.05). Factors associated with poor outcomes were structural laryngeal changes in five patients (p < 0.05) and no response to proton pump inhibitors in six patients (p < 0.05). CONCLUSIONS Fundoplication augments treatment of LPR. Improvement of symptoms continues past the first 4 months. Laryngoscopy is critical in patient selection because selected findings are associated with outcomes, diagnosis, and management.

Abstract
PURPOSE OF REVIEW Endoscopic treatment has been recently introduced as a new option for treating gastroesophageal reflux disease. In this article the authors review the radiofrequency approach known as the Stretta procedure, as more evidence has linked reflux to upper airway disease. RECENT FINDINGS Since 1968, when laryngeal disorders were linked to gastroesophageal reflux disease, more upper airway diseases such as chronic laryngitis, subglottic stenosis, and even laryngeal carcinoma were found to be occasionally caused by extraesophageal reflux. Most otolaryngologists treat these patients with proton pump inhibitors, which improve symptoms in two thirds of patients. Antireflux surgery remains the treatment of choice, relieving symptoms in more than 90% of patients. Endoscopic treatment has recently emerged as an option for treatment of gastroesophageal reflux disease. The Stretta procedure delivers radiofrequency energy to the gastroesophageal junction. This has proved to be effective in controlling reflux by inhibiting transient, inappropriate lower esophageal sphincter relaxation, increasing postprandial lower esophageal spincter pressure, and decreasing lower esophageal sphincter compliance. Stretta is among the earliest endoscopic technologies to be approved by the Food and Drug Administration for the treatment of reflux. It has the longest term follow-up published to this date, and the most durable effect. It is performed under intravenous sedation on an outpatient basis and has a low incidence of complications. SUMMARY The Stretta procedure is an endoscopic, noninvasive modality for the treatment of gastroesophageal reflux disease. It should be considered in the treatment of reflux-related upper airway diseases.

Abstract
Manifestations of atypical gastroesophageal reflux disease (GORD) are varied, and the presentation of atypical symptoms may occur in the absence of typical symptoms. The most sensitive and specific investigation for GORD is pH monitoring, and its application in atypical disease is utilized throughout this paper as a basis for correlating disease and pathogenesis. The less well-known areas of laryngeal manifestations, particularly chronic hoarseness and globus, are discussed in addition to recent work on orodental manifestations. Well-known areas of cardiac and respiratory manifestations, which include chronic cough and asthma, are also reviewed. Evidence from clinical trials indicates that aggressive anti-reflux therapy in patients with atypical symptoms can be effective. Where appropriate, medical therapy may involve long-term proton pump inhibitor, although further research outlining the roles of other therapies such as surgery is awaited.

Abstract
Since the early 1960s, many studies have been published that consider the possible relationship between gastro-oesophageal (acid) reflux (GORD) and various other complaints, including dental erosions, ear, nose and throat problems, chronic cough and asthma. Although a high coincidence of GORD and these supra-oesophageal complaints have been noted, there is no consensus on the pathophysiology and management of such complications. In this article we review the literature published between 1966 and 2000 on this subject. We also analyse the available information on the incidence, pathophysiological mechanisms, diagnostic approach and therapeutic options in the various subgroups of disorders.

Abstract
Gastroesophageal reflux disease (GERD) has been associated increasingly with ear, nose, and throat (ENT) signs and symptoms. However, the cause and effect relationship between these two clinical entities are far from established. Many patients diagnosed initially with GERD as the cause of laryngeal signs do not symptomatically or laryngoscopically respond to aggressive acid suppression and do not have abnormal esophageal acid exposure by pH monitoring. This has resulted in frustration on the part of both gastroenterologists and ENT physicians and confusion on the part of patients. In this article we discuss the reasons for this controversy and highlight the recent data attempting to clarify this complex area.

Abstract
In patients with signs and symptoms of laryngeal disorders, laryngoscopic examination and ambulatory pH monitoring often implicate gastroesophageal reflux disease (GERD). Experimental evidence highlights the importance of acidic reflux in laryngeal disorders. However, many patients with laryngeal signs that appear to be reflux related do not respond to aggressive acid suppression. This has resulted in controversy about the exact nature of the relation between GERD and ear, nose, and throat (ENT) signs and symptoms. Use of a combination of laryngoscopic examination and 24-hour ambulatory pH testing may improve the ability to identify those patients who would most benefit from acid suppression. Currently, however, these tests lack specificity, and the relationship remains unproved. This important task will require data from large-scale, randomized, controlled studies. Until we have determined these specific laryngeal signs from both a gastroenterology and an ENT perspective, we will be forced to use empiric therapy to identify those patients whose laryngeal signs and symptoms are due to GERD. Based on present data, we recommend aggressive acid suppression with twice-daily dosing of proton pump inhibitors for >or=4 months in these patients.

Abstract
This study was conducted to review and evaluate the published evidence for an association between gastroesophageal reflux (GER) and 3 supraesophageal pathologies: sinusitis, otitis media, and laryngeal malignancy. Relevant articles were located using MEDLINE (search limits: 1966-2001, English language, human studies). Only new data or new analyses of previous data were included. Relevant articles were designated by their level of evidence, based on published standards, and grouped by pathology. An overall grade was assigned to each group for the strength of evidence for or against an association. The search produced 152 articles, 42 of which met inclusion criteria and were reviewed in detail. There is grade C evidence for a positive association between GER and sinusitis (57 articles screened, 14 articles included); for a negative association between GER and otitis media (28 articles screened, 10 articles included); and for a positive association between GER and laryngeal malignancy (67 articles screened, 18 articles included). The published literature weakly supports a positive association between GER and both sinusitis and laryngeal malignancy, and a negative association between GER and otitis media.
