RESUMO
While head and neck cancer incidence decreased worldwide due to reduced tobacco and alcohol consumption, oral tongue cancer (OTC) incidence has been reported to be increasing in several countries. Our study examines the incidence trends of OTC in France from 1990 to 2018, globally and by age; and compares the incidence trends with the evolution of the incidence of other human papilloma virus-unrelated head and neck squamous cell carcinoma, that is, cancers of the remaining subsites of the oral cavity (RSOCC) and laryngeal cancers for the period 1990 to 2018. World age-standardized incidence rates of oral tongue cancers (C02), cancers of the remaining subsites of the oral cavity (RSOCC, C03-06) and laryngeal cancers (C32) were estimated using the French National Network of Cancer Registries for the period 1990 to 2018. Trends in national incidence rates were estimated from a mixed-effect Poisson model including age and year effects using penalized splines and a district-random effect. In women aged 30 and 40, a significant increase in OTC incidence was observed, while ROSCC showed a nonsignificant incidence decrease. In young men aged 25, a marginally significant increase of OTC incidence years was observed, while incidence rates of RSOCC significantly declined. The results suggest a tendency towards diverging incidence trends for OTC compared to RSOCC and laryngeal cancer in young adults. The observed trends may reflect changes in underlying exposures or emerging exposures not yet identified, and stress the need to further investigate the etiology of oral tongue cancers.

OBJECTIVES: Head and neck squamous cell carcinomas (HNSCCs) mainly affect smokers and drinkers. However, oral cavity squamous cell cancers (OCSCCs) are increasingly affecting patients with no identified risk factors (NIRFs). This study aimed at characterising their experience of the disease. METHODS: Qualitative study based on semi-structured interviews of 20 survivors of OCSCC with NIRF. Methods used in grounded theory approach were applied. RESULTS: Patients with NIRF had a similar experience to that of patients with risk factors regarding treatments. The absence of identified causes led to stigma and led the patients to distance themselves, both from the stereotypic HNSCC cancer patient and the identity as a cancer patient. Furthermore, having no identified risk factors seemed to reinforce the fear of recurrence. CONCLUSION: This study is the first to address key gaps in knowledge regarding patients with NIRF having survived OCSCC. Their experience is similar to that of patients with orphan diseases. Owing to confrontation with other patients and the repeated questions of caregivers about tobacco/alcohol consumption, these patients felt stigmatised during their treatment. OCSCC patients with NIRF may benefit from guidance and support on how to engage in prevention.

OBJECTIVES: Main: To describe 1-year overall survival (OS) after primary or salvage management of head and neck squamous cell carcinoma (HNSCC) invading the common or internal carotid artery (CCA/ICA). Secondary: To assess disease control rate, treatment morbidity, and radio-anatomopathologic correlation. METHODS: Retrospective study of 67 patients, treated between 1999 and 2020 for N3bM0 HNSCC invading the CCA/ICA as identified by CT-scan. Tumors that could not have been resected with a complete en-bloc resection sacrificing and reconstructing the CCA/ICA were excluded. Patients were separated into two groups (primary or salvage treatment) and studied according to the type of treatment they received: radiotherapy/radiochemotherapy (RT/RCT), surgery, or systemic therapy (ST). RESULTS: For newly treated patients, the 1-year OS was significantly better after RT/RCT (73%) than after surgery (40%, p < 0.0001). In the salvage setting, the 1-year OS after surgery (40%) was better than after ST (14%, statistically suggestive difference with p = 0.0241). Surgery improved cervical control, but distant metastases occurred in more than 50% of cases regardless of treatment. No neurological complication occurred after carotid reconstruction. Perioperative mortality was 7% (1/15). The carotid invasion was confirmed by pathological examination in all five patients with an arterial deformation on CT-scan, in seven among eight patients with CCA/ICA encasement greater than 270°, and in four out of seven patients with CCA/ICA encasement between 180° and 270°. CONCLUSION: Neck dissection with carotid resection and reconstruction is technically feasible with acceptable neurovascular morbidity. For newly treated patients, survival is better after RT/RCT. For salvage treatment, surgery could be proposed to selected patients.

BACKGROUND: Incidence of oral tongue squamous cell carcinoma (OTSCC) is increasing, especially in young adults, despite decreasing tobacco and alcohol consumption. METHODS: This multicentric retrospective study of 185 young adults with OTSCC (median follow-up 43 months), investigated risk factors, tumour characteristics and oncological outcomes according to the smoking status. RESULTS: Overall, 38% of patients were smokers (S). Non-smokers (NS) were significantly younger than S. Sex ratios were 1.1 for N and 1.8 for S. NS patients were less frequently cannabis or alcohol users than S, but were more likely to have a history of leukoplakia. Second primaries were observed in NS (4.4%) and in S (12.7%). Despite more frequent local relapse in NS (p = 0.018), there was no difference in diagnostic stage and overall survival between groups. CONCLUSION: OTSCC affects differently young S and NS patients suggesting the existence of a specific clinical entity of OTSCC in non-smoking young adults.

PURPOSE: Radial forearm free flap (RFFF) being a workhorse flap in head and neck reconstruction, we investigated its donor site delayed consequences. METHODS: Multicentric case series evaluating 189 patients who underwent RFFF for carcinologic reasons at least 6 months before. Patients and surgeon's appreciation regarding the aesthetic and functional consequences of the flap harvest on their daily life were evaluated by questionnaires using likert scales. Medical data were collected from patients' charts retrospectively. RESULTS: Thirty percent of patients had at least one sequelae. Experiencing a graft necrosis did not worsen long-term results. Cosmetic satisfaction was significantly worst for women, according to patients' and surgeons' opinion. For 81% and 92% patients, respectively, the flap harvest had no impact on daily life nor sport practice. Ratio between the benefits of reconstruction and the sequelae at the donor site was judged "excellent" for 77% patients. CONCLUSIONS: Although objectively important, RFFF morbidity has little impact in head and neck cancer patient's life.

PURPOSE: The importance of occupational exposures in patients with head and neck squamous cell carcinomas (HNSCC) has received little attention. METHODS: In a single-center study, we prospectively characterized occupational exposures in 154 HNSCC cancer patients in a systematic occupational consultation and examined the association between most frequent exposures, HNSCC stage and localization. RESULTS: Patients occupied a mean of 3.3 different positions during their working life. The prevalence of asbestos, the most frequent exposure (46 patients; 29.9%) was higher than in the French population > 50 years. Other frequent exposures were solvents (n = 26; 16.9%) and silica (n = 19; 12.3%). For 37 patients (24%) a possible link was identified between occupational exposures and HNSCC. Duration of asbestos exposure was significantly higher (p = 0.04) in patients with hypopharyngeal and laryngeal cancer compared to other localizations. CONCLUSIONS: Occupational exposures are frequent in patients with HNSCC and should receive increased attention by physicians.

BACKGROUND: Oral squamous cell carcinoma is a major cause of cancer-associated morbidity and mortality and may develop from oral erythroplakia and leukoplakia (OEL), the most common oral potentially malignant lesions. Our objective was to provide a descriptive overview of the global research activity on OEL over the past decades. METHODS: We performed a systematic bibliometric analysis of articles and reviews on OEL up to December 31st 2016 using the SCOPUS database. Contribution of each country was analyzed by density-equalizing mapping (DEMP). The overall scientific productivity was analyzed for each journal and country. RESULTS: A total of 5098 published items (articles or reviews) were identified. They are expected to double by 2040, with an expected number of 400 items per year. Only 4% of all research on oral oncology is focused on OEL. Together with the increasing number of publications since 1980s, an increasing number of international collaborative studies were observed. Journal of Oral Pathology and Medicine and Oral Oncology are the leading journals in terms of number of published items. The US, India, and the UK were the most prolific countries in terms of publications overtime. CONCLUSIONS: We identified the leading journals as well as the leading authors and countries contributing to the research on OEL. International collaborative studies in the field are to be encouraged to refine strategies of oral cancer prevention.

BACKGROUND: Radiotherapy for head and neck squamous cell carcinomas (HNSCC) is associated with a substantial morbidity and inconsistent efficacy. Human papillomavirus (HPV)-positive status is recognized as a marker of increased radiosensitivity. Our goal was to identify molecular markers associated with benefit to radiotherapy in patients with HPV-negative disease. METHODS: Gene expression profiles from public repositories were downloaded for data mining. Training sets included 421 HPV-negative HNSCC tumors from The Cancer Genome Atlas (TCGA) and 32 HNSCC cell lines with available radiosensitivity data (GSE79368). A radioresistance (RadR) score was computed using the single sample Gene Set Enrichment Analysis tool. The validation sets included two panels of cell lines (NCI-60 and GSE21644) and HPV-negative HNSCC tumor datasets, including 44 (GSE6631), 82 (GSE39366), and 179 (GSE65858) patients, respectively. We finally performed an integrated analysis of the RadR score with known recurrent genomic alterations in HNSCC, patterns of protein expression, biological hallmarks, and patterns of drug sensitivity using TCGA and the E-MTAB-3610 dataset (659 pancancer cell lines, 140 drugs). RESULTS: We identified 13 genes differentially expressed between tumor and normal head and neck mucosa that were associated with radioresistance in vitro and in patients. The 13-gene expression-based RadR score was associated with recurrence in patients treated with surgery and adjuvant radiotherapy but not with surgery alone. It was significantly different among different molecular subtypes of HPV-negative HNSCC and was significantly lower in the "atypical" molecular subtype. An integrated analysis of RadR score with genomic alterations, protein expression, biological hallmarks and patterns of drug sensitivity showed a significant association with CCND1 amplification, fibronectin expression, seven hallmarks (including epithelial-to-mesenchymal transition and unfolded protein response), and increased sensitivity to elesclomol, an HSP90 inhibitor. CONCLUSIONS: Our study highlights the clinical relevance of the molecular classification of HNSCC and the RadR score to refine radiation strategies in HPV-negative disease.

Squamous cell carcinomas of the hard palate and maxillary alveolar ridge are rare tumours with a poor prognosis. Lymph node dissection is recommended for tumours with nodal involvement, and is rarely performed in the absence of adenopathy. We report a series of patients with squamous cell carcinomas and evaluate the rate of lymph node invasion and its impact on survival. This is a retrospective study of 72 patients treated for squamous cell carcinoma of the hard palate and maxillary alveolar ridge between January 1, 1998 and December 31, 2008 in two cancer centres. Using clinical and radiological assessment, tumours were classified as T1-T2 in 25 patients (34.7%) and T3-T4 in 47 patients (65.3%). At diagnosis, 16 (22.2%) patients had clinical and/or radiological nodal involvement and 7 patients (9.7%) distal metastasis. Among N0 patients, 13 (18%) experienced isolated lymph node recurrence. Two-year global survival was 60%; 5-year survival was 34%. The rate of lymph node invasion observed in squamous cell carcinoma of the hard palate and maxillary alveolar ridge does not differ from other oral cavity sites. Because nodal recurrence worsens the prognosis of such a patient, lymph node dissection should be considered at an early stage, even among N0 patients.

STATEMENT OF PROBLEM: Mandibular reconstruction with a microvascular free fibula flap is widely used after oncologic resection because it allows functional and esthetic restoration of the mandibular arch and implant-retained prostheses. PURPOSE: The purpose of this study was to highlight the results that can be expected from an implant-supported prosthesis on a free fibula flap. MATERIAL AND METHODS: Patients treated with a microvascular free fibula flap and rehabilitated prosthetically were included. The number of osteotomies, number of implants, type of prosthesis, follow-up after placement of the prosthesis, preimplant surgery, and periimplant complications were reported. Subjective criteria, including patient satisfaction and improvement of masticatory function, were collected by means of a questionnaire that covered the type of diet, restrictions when eating, intelligibility of speech, and communication levels. RESULTS: Twenty-six patients were included: 11 patients had implant-supported dentures, and 15 had fixed prostheses. Prosthetic follow-up was over 5 years for 15 patients and less than 1 year for 2 patients. Hyperplasia was a periimplant complication for 7 patients. Overall, satisfaction was good for 24 patients (score greater than 5/10; mean score, 7.3/10). Esthetics were improved for 20 patients. Speech was improved for 6 patients, and diet improved for 9 patients. CONCLUSIONS: Implant-retained dentures seem preferable for patients, with notable esthetic alteration, although a screw-retained fixed resin-bonded prosthesis remains a good alternative. Improved mastication is more notable with patients who are completely edentulous and with large reconstructions but nevertheless remains disappointing. Whether dental restoration is necessary in treatments with short lateral flaps is worth questioning.

Background: Major advances have been made in reconstructive surgery in the last decades to reduce morbidity in head and neck cancer. Flaps are now present in 80% of patients with oral cavity cancer to cover anatomic, functional, and cosmetic needs. However, gaps in interdisciplinary innovation transfer from surgery to postoperative radiotherapy (poRT) remain challenging. We aimed to provide an interdisciplinary view of the challenges encountered by radiation oncologists in planning head and neck postoperative radiotherapy. Methods: A systematic and critical review was conducted to address areas of optimization in surgery and radiology that may be relevant to poRT. Results: Despite extensive surgical literature on flap techniques and salvage surgery, 13 retrospective series were identified, where flap outcomes were indirectly compared between surgery alone or poRT. These low-evidence studies suggest that radiotherapy accelerates flap atrophy, fibrosis, and osteoradionecrosis and deteriorates functional outcomes. Preliminary evidence suggests that tumor spread occurs at the flap-tissue junction rather than in the flaps. One prospective 15-patient study showed 31.3% vs. 39.2% flap volume reduction without or with poRT. In an international consensus, experts recognized the needs for optimized flap-sparing poRT against flap-related functional deterioration and bone damage. CT, MRI, and PET-CT modalities show potential for the delineation of the junction area between native tissues and flap for flap segmentation and to characterize flap-specific changes quantitatively and correlate them with patterns of relapse or complications. Conclusion: Flap management in poRT is insufficiently documented, but poRT seems to damage flaps. Current gaps in knowledge underscore the need for prospective flap assessment and interdisciplinary trials investigating flap morbidity minimization by flap-sparing poRT planning.
RESUMO
The management of head and neck cancers is multidisciplinary, often relying on the use of combined treatments to maximize the chances of cure. Combined treatments are however also responsible for cumulative side effects. The aim of reconstructive surgery with a flap is to restore a function lost with the loss of substance from the tumor resection. However, changes in reconstructive surgery have impact of postoperative radiotherapy planning. The optimization of imaging protocols for radiotherapy planning should make it possible to identify postoperative changes and to distinguish flaps from surrounding native tissues to delineate the flaps and document the spontaneous evolution of these flaps or dose-effect relationships in case of radiotherapy. Such changes include atrophy, fibrosis of soft tissue flaps and osteoradionecrosis of bone flaps. Radiotherapy optimization also involves standardization of the definition of target volumes in situations where a flap is present, a situation that is increasingly common in routine care. This evolution of practice, beyond the essential multidisciplinary consultation meetings defining treatment indications, requires a close radio surgical collaboration with respect to technical aspects of the two disciplines. Doing so, anticipation of relapse and toxicity profiles could possibly lead to propose strategies for personalized de-escalation of multimodal treatments through interdisciplinary trials.

The quest for targeted therapies is critical in the battle against cancer. The RAS/MAP kinase pathway is frequently implicated in neoplasia, with ERK playing a crucial role as the most distal kinase in the RAS signaling cascade. Our previous research demonstrated that the interaction between ERK and MYD88, an adaptor protein in innate immunity, is crucial for RAS-dependent transformation and cancer cell survival. In this study, we examine the biological consequences of disrupting the ERK-MYD88 interaction through the ERK D-recruitment site (DRS), while preserving ERK's kinase activity. Our results indicate that EI-52, a small-molecule benzimidazole targeting ERK-MYD88 interaction induces an HRI-mediated integrated stress response (ISR), resulting in immunogenic apoptosis specific to cancer cells. Additionally, EI-52 exhibits anti-tumor efficacy in patient-derived tumors and induces an anti-tumor T cell response in mice in vivo. These findings suggest that inhibiting the ERK-MYD88 interaction may be a promising therapeutic approach in cancer treatment.

OBJECTIVES: The management of upper aerodigestive tract cancers is a complex specialty. It is essential to provide an update to establish optimal care. At the initiative of the INCa and under the auspices of the SFORL, the scientific committee, led by Professor Béatrix Barry, Dr. Gilles Dolivet, and Dr. Dominique De Raucourt, decided to develop a reference framework aimed at defining, in a scientific and consensus-based manner, the general principles of treatment for upper aerodigestive tract cancers applicable to all sub-locations. METHODOLOGY: To develop this framework, a multidisciplinary team of practitioners was formed. A systematic analysis of the literature was conducted to produce recommendations classified by grades, in accordance with the standards of the French National Authority for Health (HAS). RESULTS: The grading of recommendations according to HAS standards has allowed the establishment of a reference for patient care based on several criteria. In this framework, patients benefit from differentiated care based on prognostic factors they present (age, comorbidities, TNM status, HPV status, etc.), conditions of implementation, and quality criteria for indicated surgery (operability, resectability, margin quality, mutilation, salvage surgery), as well as quality criteria for radiotherapy (target volume, implementation time, etc.). The role of medical and postoperative treatments was also evaluated based on specific criteria. Finally, supportive care must be organized from the beginning and throughout the patients' care journey. CONCLUSION: All collected data have led to the development of a comprehensive framework aimed at harmonizing practices nationally, facilitating decision-making in multidisciplinary consultation meetings, promoting equality in practices, and providing a state-of-the-art and reference practices for assessing the quality of care. This new framework is intended to be updated every 5 years to best reflect the latest advances in the field.

BACKGROUND: The global popularity of cosmetic surgery, combined with mass media attention on medical consumerism, has resulted in misinformation that may have negatively affected the "collective image" of aesthetic practitioners. OBJECTIVES: The authors assess patients' perceptions of cosmetic surgery and analyze their decision-making processes. METHODS: During a 2-year period, 250 consecutive patients presenting to either of 2 public hospitals for cosmetic surgery treatment were asked to complete a 7-item questionnaire evaluating their knowledge of opinions about, and referring practices for, aesthetic procedures. Patients undergoing oncologic, postbariatric, or reconstructive procedures were not included in the study. RESULTS: After exclusion of 71 cases for refusal or incompletion, 179 questionnaires were retained and analyzed (from 162 women and 17 men). Overall, repair (70.4%), comfort (45.3%), and health (40.8%) were the words most frequently associated with cosmetic surgery. Quality of preoperative information (69.3%), patient-physician relationship (65.4%), and results seen in relatives/friends (46.3%) were the most important criteria for selecting a cosmetic surgeon. Moreover, 82.7% of patients knew the difference between cosmetic surgery and cosmetic medicine. CONCLUSIONS: Although potential patients appear to be more educated about cosmetic surgery than they were several years ago, misinformation still persists. As physicians, we must be responsible for disseminating accurate education and strengthening our collaboration with general practitioners to improve not only our results but also the accuracy of information in the mass media.

OBJECTIVES: To describe the evolution of the incidence of oral cavity cancers (OCC) among elderly patients in France between 1990 and 2018 and to compare it to the incidence of other cancers sharing the same main risk factors. MATERIAL AND METHODS: The incidence of cancers in mainland France from 1990 to 2018 was estimated from incidence data observed in every cancer registry of the Francim network. Incidence was modeled by a 2-dimensional penalized spline of age and year of diagnosis, associated with a random effect corresponding to the registry. The elderly population was divided into two groups: 70-79 years old and ≥80 years old. RESULTS: There was a 72% increase in the number of OCC cases in women over 70 years of age between the periods 1990-1999 and 2010-2018. As for men, there was a stabilization in the number of cases (+2%). Over the same period, for laryngeal and hypopharyngeal cancers, there was a decrease in incidence in elderly men and an increase in elderly women, although less marked than for OCC. CONCLUSIONS: Since the 1990s, the incidence of OCC has been increasing in elderly subjects in France, particularly in women. Population aging and growth or alcohol and tobacco consumption alone do not seem to explain this increase, which is not observed in the same proportions for other upper aerodigestive tract cancer subsites sharing the same main risk factors.
RESUMO
Head and neck (HN) squamous cell carcinomas (SCCs) originate from the epithelial cells of the mucosal linings of the upper aerodigestive tract, which includes the oral cavity, the pharynx, the larynx, and the sinonasal cavities. There are many associated risk factors, including alcohol drinking coupled with tobacco use, which accounts for 70% to 80% of HNSCCs. Human papilloma virus (HPV) is another independent risk factor for oropharyngeal SCC, but it is only a minor contributor to oral cavity SCC (OSCC). Betel quid chewing is also an established risk factor in southeast Asian countries. However, OSCC, and especially oral tongue cancer, incidence has been reported to be increasing in several countries, suggesting risk factors that have not been identified yet. This review summarizes the established risk factors for oral cavity squamous cell carcinomas and examines other undemonstrated risk factors for HNSCC.
RESUMO
The incidence of the mobile tongue cancer in young patients has been rising. This oral cancer (OC) type has no identified risk factors (NIRF), no established molecular markers and is not yet recognized as a distinct clinical entity. To understand this emerging malignancy, we innovatively analyzed the public head and neck cancer multi-omics data. We identified mutational signatures that successfully stratified 307 OC and 109 laryngeal cancer cases according to their clinico-pathological characteristics. The NIRF OCs exhibited significantly increased activities of endogenous clock-like and APOBEC-associated mutagenesis, alongside specific cancer driver gene mutations, distinct methylome patterns and prominent antimicrobial transcriptomic responses. Furthermore, we show that mutational signature SBS16 in OCs reflects the combined effects of alcohol drinking and tobacco smoking. Our study characterizes the unique disease histories and molecular programs of the NIRF OCs revealing that this emerging cancer subtype is likely driven by increased endogenous mutagenesis correlated with responses to microbial insults.
RESUMO
OBJECTIVE: Radiotherapy (RT) against head and neck squamous cell carcinomas (HNSCC) may lead to severe toxicity in 30-40% of patients. The normal tissue complication probability (NTCP) models, based on dosimetric data refined the normal tissue dose/volume tolerance guidelines. In parallel, the radiation-induced nucleoshuttling (RIANS) of the Ataxia-Telangiectasia Mutated protein (pATM) is a predictive approach of individual intrinsic radiosensitivity. Here, we combined NTCP with RADIODTECT©, a blood assay derived from the RIANS model, to predict RT toxicity in HNSCC patients. METHODS: RADIODTECT© cutoff values (i.e. 57.8 ng/mL for grade⩾2 toxicity and 46 ng/mL for grade⩾3 toxicity) have been previously assessed. Validation was performed on a prospective cohort of 36 HNSCC patients treated with postoperative RT. Toxicity was graded with the Common Terminology Criteria for Adverse Events (CTCAE) scale and two criteria were considered: grade⩾2 oral mucositis (OM2), grade⩾3 mucositis (OM3) and grade⩾2 dysphagia (DY2), grade⩾3 dysphagia (DY3). pATM quantification was assessed in lymphocytes of HNSCC patients. The discrimination power of the pATM assay was evaluated through the Area Under the Receiver Operator Characteristics Curve (AUC-ROC). Two previously described NTCP models were considered, including the dose to the oral cavity and the mean dose to the parotid glands (OM2 and OM3) and the dose to the oral cavity, to the larynx and the volume of pharyngeal constrictor muscles (DY2 and DY3). RESULTS: Combining NTCP models with RADIODTECT© blood test improved the AUC-ROC. Considering the prediction of mucositis, AUC-ROCNTCP+RADIODTECT©=0.80 was for OM2, and AUC-ROCNTCP+RADIODTECT©=0.78 for OM3. Considering the prediction of acute dysphagia, AUC-ROCNTCP+RADIODTECT©=0.71 for DY2 and for DY3. CONCLUSIONS: Combining NTCP models with a radiosensitivity biomarker might significantly improve the prediction of toxicities for HNSCC patients.
