Early diagnosis of oral cavity carcinomas: The best prognostic factor

Oral mucosa neoplasms are most often pre-malignant lesions that evolved in squamous cell carcinoma (90% of cancers of the oral cavity). Tobacco and alcohol are the two most incriminated etiological factors. Other etiologies have also been mentioned, in particular the oncogenicity of certain viruses like the human papillomavirus(HPV). However, other types of cancer may occur mainly in young adults whose starting point is generally a salivary gland (10% of cancers of the oral cavity). From two clinical cases, squamous cell carcinoma and mucoepidermoid carcinoma, we describe the etiopathogenesis and the clinical characteristics as well as the histopathological particularities, diagnosis and prognosis of each of these entities. We also developped the interest of an early detection of the lesions that will provide the patient a better prognosis even though the therapeutic strategy is established in the best condition

Marginal versus Segmental Mandibulectomy in the Treatment of Oral Cavity Cancer: A Systematic Review and Meta-analysis

Introduction Oral cavity squamous cell carcinoma (OCSCC) is the most common malignancy in the oral cavity. Two types of mandibular resections have been described: the segmental mandibulectomy and the marginal mandibulectomy. Both may have a different impact over the quality of life, oncological prognosis, and functional or aesthetic result.Objectives The aim of this study was to systematically explore the literature to determine the survival outcomes and disease control rates in patients who underwent segmental or marginal mandibulectomy for OCSCC with histological evidence of cortical and medullary bone invasion.Data Synthesis This review involved a systematic search of the electronic databases MEDLINE/PUBMED, Google Scholar, Ovid Medline, Embase, and Scopus including articles from 1985 to 2019. Fifteen articles were included for qualitative analysis and 11 articles were considered for meta-analysis calculations. All of them correspond to retrospective cohort studies.Conclusion This systematic review reveals the low-level evidence regarding the impact over local control or survival according to the type of mandibulectomy. Our results need to be considered with precaution according to the limited evidence available. We just found difference regarding the 5-year disease-free survival, and a tendency in favor of segmental mandibulectomy was confirmed when medullary invasion was evident

Systematic review of international guidelines for perioperative antibiotic prophylaxis in Head & Neck Surgery. A YO-IFOS Head & Neck Study Group Position Paper.

BACKGROUND: Surgical site infection (SSI) is defined as an infection that occurs after a surgical incision or organ manipulation during surgery. The frequency reported for clean head and neck surgical procedures without antimicrobial prophylaxis is <1%. In contrast, infection rates in patients undergoing complicated cancer surgery are high, ranging from 24% to 87% of patients without antimicrobial prophylaxis. METHODS: Guidelines and recommendations about the use of antibiotics in head and neck surgery from 2004 to 2019 were reviewed. RESULTS: Four guidelines from Oceania, 5 from South America, 5 from North America, 2 from the United Kingdom, 11 from Europe, 1 from Africa, 1 from the Middle East, and 3 from Asia were included. A total of 118 papers were included for analysis and recommendation. CONCLUSION: Antibiotic prophylaxis can decrease the incidence of SSI. However, the risks associated with antibiotic exposure and the risk of antibiotic resistance need to be taken into consideration

MET Genetic Abnormalities Unreliable for Patient Selection for Therapeutic Intervention in Oropharyngeal Squamous Cell Carcinoma

Background: Identification of MET genetic alteration, mutation, or amplification in oropharyngeal squamous cell carcinoma (OPSCC) could lead to development of MET selective kinase inhibitors. The aim of this study was to assess the frequency and prognostic value of MET gene mutation, amplification, and protein expression in primary OPSCC. Methods: A retrospective chart review was conducted of patients treated for single primary OPSCC between January 2007 and December 2009. Pre-treatment OPSCC tissue samples were analyzed for MET mutations, gene amplification, and overexpression using Sanger sequencing, FISH analysis, and immunohistochemistry respectively. Univariate and multivariate analyses were used to analyze correlations between molecular abnormalities and patient survival. Results: 143 patients were included in this study. Six cases (4%) were identified that had a genetic variation, but previously described mutations such as p. Tyr1235Asp (Y1235D) or p.Tyr1230Cys (Y1230C) were not detected. There were 15 high polysomy cases, and only 3 cases met the criteria for true MET amplification, with >= 10% amplified cells per case. Immunohistochemistry evaluation showed 43% of cases were c-MET negative and in 57% c-MET was observed at the tumor cell level. Multivariate analysis showed no significant association between MET mutation, amplification, or expression and survival. Conclusions: Our study shows a low frequency of MET mutations and amplification in this cohort of OPSCC. There was no significant correlation between MET mutations, amplification, or expression and patient survival. These results suggest that patient selection based on these MET genetic abnormalities may not be a reliable strategy for therapeutic intervention in OPSCC

Surgical, clinical and functional outcomes of transoral robotic surgery for supraglottic laryngeal cancers: A systematic review

International audienceBackground: The aim of this systematic review is to shed light the current indications and outcomes of transoral robotic surgery (TORS) supraglottic laryngectomy (SGL) in patients with supraglottic laryngeal cancer. Methods: PubMed, Scopus and Cochrane Library were searched by three independent otolaryngologists from the Young Otolaryngologists of IFOS for studies investigating the indications, effectiveness and safety of TORS SGL. Surgical, functional, and survival outcomes have been investigated. Inclusion/exclusion criteria; demographic data; and clinical outcome evaluation of papers were analyzed using PRISMA criteria. Results: A total of 14 papers met our inclusion criteria, accounting for 422 patients (335 males & 87 females). The tumor location mainly consisted of epiglottis (55.4%), aryepglottic fold (31.2%), and ventricular band (5.1%). The following tumor stages were considered: cT1 (35.8%); cT2 (48.6%) and cT3 (13.9%). Feeding tube and percutaneous endoscopic gastrostomy were used in 62.5% and 8.82% of patients, respectively. The 24-month local & regional control rates ranged from 94.3% to 100% and 87.5% to 94.0%, respectively. The 2-year and 5-year overall survival rates ranged from 66.7% to 88.0% and 78.7% to 80.2%, respectively. There was an important heterogeneity between studies with regard to the inclusion/exclusion criteria, follow-up times, complications analysis; surgical and functional outcomes. Conclusion: TORS SGL is an effective approach for treating patients with early stages supraglottic cancers. Future controlled studies are needed to compare functional and survival outcomes between TORS SGL and other surgical approaches. Recommendations have been provided for future studies for better inclusion of patients, analysis of complications and functional outcomes

Surgical, clinical, and functional outcomes of transoral robotic surgery used in sleep surgery for obstructive sleep apnea syndrome: A systematic review and meta-analysis

International audienceWe investigated safety and efficacy of transoral robotic surgery (TORS) for base of tongue (BOT) reduction in obstructive sleep apnea syndrome (OSAS) patients. PubMed, Cochrane Library, and Scopus were searched. A meta-analysis was performed. Random effects models were used. Thirty-one cohorts met our criteria (1693 patients). The analysis was based mostly on retrospective studies. The summary estimate of the reduction of Apnea–Hypoxia Index (AHI) was 24.25 abnormal events per hour (95% CI: 21.69–26.81) and reduction of Epworth Sleepiness Scale (ESS) was 7.92 (95% CI: 6.50–9.34). The summary estimate of increase in lowest O2 saturation was 6.04% (95% CI: 3.05–9.03). The success rate of TORS BOT reduction, either alone or combined with other procedures, was 69% (95% CI: 64–79). The majority of studies reported low level of evidence but suggested that TORS BOT reduction may be a safe procedure associated with improvement of AHI, ESS, and lowest O2 saturation

Management of oral feeding following total laryngectomy around the world: YO‐IFOS international study

International audienceBackground: To analyze worldwide practices regarding the initiation of oral feeding after total laryngectomy (TL).Methods: Online survey.Results: Among the 332 responses received, 278 from 59 countries were analyzed. Our results showed that 45.6% of respondents started water and 45.1% started liquid diet between postoperative days 7 and 10. Semi-solid feeds were initiated between days 10 and 14 for 44.9% of respondents and a free diet was allowed after day 15 for 60.8% of respondents. This timing was significantly delayed in cases of laryngo-pharyngectomy and after prior radiotherapy (p < 0.001). A greater proportion of respondents in Africa and Oceania allowed early oral feeding before day 6 as compared with the rest of the world (p < 0.001).Conclusion: Despite increasing number of publications, there is still a lack of evidence to support early oral feeding. The majority of respondents preferred to delay its initiation until at least 7 days after surgery
