Oral cavity cancer is a type of head and neck squamous cell carcinoma (HNSCC) and contributes to significant morbidity and mortality each year. An epigenetic pathway of transcriptional inactivation for many genes has been described in various cancers, including HNSCC. For our study, we selected genes for which silencing caused by hypermethylation can promote cancer development. In 75 primary HNSCC tumours and paired surgical margins, we investigated the methylation status of the p16, APC, MGMT, TIMP3 and CDH1 gene promoters by methylation-specific PCR after bisulphite treatment. The promoter methylation rates of p16, APC, ...

Endothelial nitric oxide synthase (eNOS) was reported to modulate carcinogenesis and progression through nitric oxide (NO) production. Genetic polymorphisms in the eNOS gene can regulate its transcription and further mediate NO production. The purpose of this study was to exp...

AbstractTo evaluate the utility of the pectoralis major myocutaneous (PMMC) flap for the reconstruction of the mandible in advanced oral cavity malignancies in the Indian population. It was a retrospective study contained 30 patients with advanced oral cancer from July 2012 to August 2016. The PMMC reconstruction was done in all the patients to repair the bony defects in segmental/hemi mandibulectomy. The patients were followed up for a mean period of 6  months in the postoperative period and the utility of the PMMC flaps were evaluated. The mean age of the patients was 45 years (range 30–63 years). Th...

Abstract Following breast and lung cancers, renal cell carcinoma (RCC) is the third most frequent cancer to metastasize to the head and neck region, though such cases are rarely reported. Distinguishing between malignant tumors of salivary gland origin and metastatic RCC is very important. The case of a 75-year-old man with an oral cavity lesion in the left buccal submucosa measuring 40×30 mm that had grown substantially over several weeks is presented. His medical history included left kidney cancer 26 years earlier and a malignant myoepithelioma of the left buccal region 7 years earlier. It was suspected t...

Rogers To examine associations between socioeconomic status and the extent to which patients with cancer of the head and neck expressed concerns to surgeons during routine follow-up clinics, we analysed audio recordings of 110 consultations with one consultant. We used the Verona Coding Definitions of Emotional Sequences (VRCoDES) to measure communication between the doctor and the patient, and grouped the English indices of multiple deprivation (IM...

CONCLUSIONS: Polymorphic variant XRCC1 HNSCC patients treated with CCRT have significantly increased acute radiation morbidities and may have a trend toward better PFS in comparison with the wild variant. PMID: 29893275 [PubMed - in process]

CONCLUSION: The prevalence of HNSCC is modest compared with other cancers in HIV-infected individuals. The prevalence of oropharynx carcinoma, a potentially HPV-related carcinoma, seems to increase over time. Even if tobacco may be an important contributor, the role of HPV in HIV-infected individuals presenting with HNSCC should be investigated. PMID: 29887186 [PubMed - as supplied by publisher]

To examine associations between socioeconomic status and the extent to which patients with cancer of the head and neck expressed concerns to surgeons during routine follow-up clinics, we analysed audio recordings of 110 consultations with one consultant. We used the Verona Coding Definitions of Emotional Sequences (VRCoDES) to measure communication between the doctor and the patient, and grouped the English indices of multiple deprivation (IMD) 2015 scores into deciles to compare the VRCoDES with socioeconomic status.

Xerostomia (dry mouth) is the most common side effect of radiation therapy in patients with head and neck cancer and causes difficulty speaking and swallowing. Since aldehyde dehydrogenase 3A1 (ALDH3A1) is highly expressed in mouse salivary stem/progenitor cells (SSPCs), we sought to determine the role of ALDH3A1 in SSPCs using...
