Kannan N, Pandiar D, Subramanian R, Krishnan RP, S C. Helicobacter pylori positive oral squamous cell carcinoma demonstrate higher pathological tumor staging and poorer overall survival. JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2024; 125:101952. [PMID: 38906379 DOI: 10.1016/j.jormas.2024.101952] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/28/2024] [Revised: 06/05/2024] [Accepted: 06/18/2024] [Indexed: 06/23/2024]
Abstract
BACKGROUND Helicobacter pylori (H pylori), a bacterium characterized by its spiral shape and gram-negative nature, impacts approximately half of the global population, showing a greater prevalence in developing nations. There are various factors that contribute to the pathogenicity of H pylori in the gastric mucosa, leading to gastric ulcer, gastritis and gastric cancers. The relationship between H pylori and gastric cancers has been well documented. The association between Oral Squamous Cell Carcinoma (OSCC) and H pylori still remains a grey field. The study aimed to evaluate the presence of H pylori in OSCC. MATERIALS AND METHODS The study consisted of 46 case samples and 21 controls. The case samples comprised of histopathologically confirmed cases of OSCC obtained from patients undergoing wide local excision. Fresh tissue samples were collected during cryosection and stored in eppendorf tubes. The control samples were collected from the gingiva and buccal mucosa of apparently healthy patients with no history of habits, undergoing procedures such as gingivectomy and impaction. All the cases and controls were subjected to immunohistochemistry for Helicobacter pylori antibody. The cases demonstrating Helicobacter pylori in immunohistochemistry further underwent additional Real-Time- Polymerase Chain Reaction (RT-PCR) and culture methodology for subsequent confirmation. RESULTS 15/46 cases (32.6 %) showed positive immunohistochemical expression of H pylori in OSCC, while all the twenty-one controls were negative (p value 0.001). Out of the 15 cases tested using culture methodology, a total of 7 cases, representing 46.7 % of the sample, were positive for the presence of H pylori (p- value 0.003). Similar statistically significant results were also obtained for 16S rRNA gene with RT- PCR. Furthermore, H pylori positive cases were frequently found in higher pathological tumor staging. A significant increase in overall survival rate was evident among the H pylori negative cases. CONCLUSION Helicobacter pylori was significantly expressed in OSCC tissues when compared to healthy tissues. Immunohistochemical analysis of the presence of H pylori in FFPE OSCC samples yielded more positive results when compared to culture and PCR methodology. We opine that in OSCC, H pylori may have a role in the faster progression of the disease, rather than merely a 'chance spectator'.

Abstract
BACKGROUND It is controversial that Helicobacter pylori (H pylori) is involved in the pathogenesis or development of laryngopharyngeal reflux disease (LPRD). OBJECTIVE To investigate the potential association between LPRD and H pylori infection. MATERIAL AND METHODS A systematic review was performed of studies assessing the diagnosis or treatment of LPRD among patients with H pylori infection. Data sources are PubMed/MEDLINE, EMBASE[Ovid], Cochrane Library, and Web of Science, and ClinicalTrials.gov. RESULTS Fifteen studies were analyzed in the review, with all eligible for the meta-analysis. A significant association between H pylori infection and LPRD was detected for higher rates of H pylori infection in patients with LPRD than in non-LPRD patients (relative risk (RR), 1.35; 95% CI, 1.12-1.63; P = 0.002), and H pylori-positive patients had a higher prevalence of LPRD than H pylori-negative patients (RR, 1.19; 95% CI, 1.07-1.31; P = 0.001). The prevalence of H pylori among patients with LPRD was 49% (95% CI, 36-61), the prevalence of H pylori among patients with non-LPRD was 35% (95% CI, 23-49). CONCLUSION AND SIGNIFICANCE The limited evidence indicated the association between LPRD risk and increased H pylori infection. Different population races, diagnostic approach to LPRD, variant H pylori testing methods, age and sex may contribute to the heterogeneity. Further well-designed studies regarding the efficacy of H pylori eradication in the treatment of LPRD are strongly recommended in the future.

Abstract
OBJECTIVE To investigate the effect of Helicobacter pylori (HP) eradication therapy on salivary pepsin concentration in laryngopharyngeal reflux (LPR) patients with HP infection. MATERIALS AND METHODS A total of 477 patients with suspected LPR were enrolled from June 2020 to September 2021. Reflux symptom index, reflux finding score, the positive rates and disintegrations per minute values of HP infection detected by 14C urea breath test and salivary pepsin concentrations analyzed using enzyme-linked immunosorbent assay were compared in LPR patients and non-LPR patients with or without HP infection. HP-positive patients were treated with HP eradication therapy while HP-negative patients with PPI therapy. RESULTS The scores of nagging cough (0.88 vs. 0.50, P = 0.035), erythema or hyperemia (1.93 vs. 1.78, P = 0.035) and vocal fold edema (1.04 vs. 0.85, P = 0.025) were higher in the LPR (+) Hp (+) subgroup than in LPR (+) Hp (-) subgroup. The concentrations of salivary pepsin in the Hp (+) subgroup were higher than in the Hp (-) subgroup either in LPR patients (75.24 ng/ml vs. 61.39 ng/ml, P = 0.005) or the non-LPR patients (78.42 ng/ml vs. 48.96 ng/ml, P = 0.024). Compared to baseline (before treatment), scores of nagging cough (0.35 vs. 0.84, P = 0.019) and erythema or hyperemia (1.50 vs. 1.83, P = 0.039) and the concentrations of salivary pepsin (44.35 ng/ml vs. 74.15 ng/ml, P = 0.017) in LPR patients with HP infection decreased after HP treatment; yet, this was not observed for the LPR patients without HP infection treated with PPI only (P > 0.05). CONCLUSION HP infection may aggravate the symptoms and signs of LPR patients, partly by increasing their salivary pepsin concentration.

Abstract
Background Laryngeal carcinoma is a primary malignant tumor originating from the laryngeal mucosa. In recent years, an increasing number of studies have confirmed that Helicobacter pylori may play a role in the occurrence and development of laryngeal cancer. We conducted a systematic review and meta-analysis to identify and emphasize the relationship between laryngeal cancer and Helicobacter pylori infection. Methods We actively searched for systematic reviews of PubMed, Embase, Web of Science, and Cochrane libraries to select studies that met the recommended guidelines. A total of 1756 patients with laryngeal cancer were included in this study to assess the association of Helicobacter pylori in the larynx with laryngeal cancer. A subassessment of the risk of bias for each study that met the inclusion criteria was carried out. To illustrate the reasons for heterogeneity, we performed a subgroup analysis to determine the type of study, the quality of the article, the diagnostic method, and the impact of exposure factors. Results The meta-analysis included a total of 17 case-control studies on the association between Helicobacter pylori in the larynx and laryngeal cancer. Our meta-analysis showed that Helicobacter pylori infection in the larynx significantly increased the risk of malignant tumors in the larynx (odds ratio, 2.96; 95% CI, 1.83-4.78; P<0.00001; I2 = 86%). They still existed when we controlled for patients’ exposure to smoking factors (odds ratio, 3.86; 95% CI, 1.89–7.88). Conclusion This systematic review and meta-analysis showed an association between Helicobacter pylori and laryngeal cancer. These findings are consistent with the understanding that chronic inflammatory tissue insult may lead to the development of malignancy. Controlling risk factors will help us identify patients with an increased risk of laryngeal cancer.

Genome of Helicobacter pylori and Serotype of HPV Detected in Oropharyngeal and Laryngeal Cancer and Chronic Inflammation Patients. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18189545. [PMID: 34574466 PMCID: PMC8470705 DOI: 10.3390/ijerph18189545] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 09/05/2021] [Accepted: 09/07/2021] [Indexed: 12/18/2022]
Abstract
Objective: Oropharyngeal/laryngeal carcinoma are common cancers of the upper aerodigestive system. Human papillomavirus (HPV) is described as the most frequent in the cancer of unknown primary. The presence of Helicobacter pylori (HP) in the oral cavity is discussed in some papers. The aim of study: To analyze the incidence of HPV and HP in oropharyngeal/laryngeal cancer persons versus persons with chronic tonsillar inflammation and healthy persons. Methods: The samples were taken in three groups: (1) tissue of oropharynx/larynx cancer (103 specimens); (2) tissue of palatine tonsils (85 specimens); and (3) healthy control group (50 specimens). We analyzed the presence of HP (PCR) and HPV genomic DNA (Sacace HPV High-Risk Screen Real-TM Quant) in the samples. Results: HP was detected in 86 samples (83.5%) and high-risk HPV in 62 samples (60.2%). We found a very high incidence of HP. In the cancer group, HP was detected in 82.5% cases and HPV positivity in 57.8%. In total, 7.2% of the cancer patients were negative for HP and HPV together. In turn, 53.6% of the cancer patients were positive for HP and HPV together. Four cases (4.2%) were positive for HPV only. VacA positivity was detected in 82 (79.6%) of the cancer cases and VacA negativity in 21 (20.4%) if the cancer cases. The incidence of HP in chronic inflammation (n = 85) was 65 cases (76.5%) and the incidence of HPV was 38 cases (44.7%). VacA positivity was detected in 59 (69.4%) of the chronic inflammation cases and VacA negativity was found in 26 (30.6%) of the chronic inflammation cases. Regarding the control group, we found HP positivity in 5 cases (11.1%) and HPV positivity in 19 cases (42.2%). There was VacA positivity in 6 cases (50.0%) of the control group. Statistically significantly lower prevalence of HP (p < 0.001) and HPV (p = 0.006) was found in the control group. Conclusions: We suggest that the palatine tonsils are colonized by HP. In our study, HP was present in oropharyngeal cancer in more cases in comparison with HPV infection. The presence of VacA from HP can have an influence on the human epithelial and immune cells’ regulation ways. Our results do not support idea that the CagA-positive HP is a primary carcinogen in oropharyngeal area.

Abstract
Helicobacter pylori (H. pylori) infection involves the development of gastric cancer and may be associated with laryngeal cancer. However, laryngeal H. pylori infection in Taiwanese patients with newly diagnosed laryngeal cancer has not been reported. This study was aimed to investigate the possible association between laryngeal H. pylori infection and laryngeal cancer in Taiwan and perform a systematic review of previous reports in other countries. An analysis of 105 patients with laryngeal lesions found the positive rates of H. pylori DNA (determined by polymerase chain reaction) and antigen (determined by immunohistochemistry) of the laryngeal lesions were relatively low (vocal polyps: 3% and 3%; vocal fold leukoplakia: 0% and 0%; laryngeal cancers: 0% and 2%). Furthermore, H. pylori-associated laryngopharyngeal reflux and the expression of E-cadherin and CD1d (determined by immunohistochemistry) were comparable among the three subgroups. Fifteen studies were involved in the systematic review of the digital literature database, distributed to February 2021. The data of patients with laryngeal cancer and controls showed that the laryngeal H. pylori infection rates were 29.4% and 16.7%, respectively. Although current evidence supported that laryngeal H. pylori infection was associated with laryngeal cancer globally, it might not play a role in the development of laryngeal cancer in Taiwan.
