Classificatory updates in verrucous and cuniculatum carcinomas:Insights from the 5^(th) edition of WHO-IARC head and neck tumor classification

The International Agency for Research on Cancer(IARC)and World Health Organization(WHO)collaboratively produce the'WHO Blue Books'essential tools standardizing the diagnostic process for human cancers.Regular updates in this classification accommodate emerging molecular discoveries,advances in immunohistochemical techniques,and evolving clinical insights.The 5th edition of the WHO/IARC classification of head and neck tumors refines the'Oral Cavity and Mobile Tongue'chapter,including sections for non-neoplastic lesions,epithelial tumors,and tumors of uncertain histogenesis.Notably,the epithelial tumors section is rearranged by tumor behavior,starting with benign squamous papillomas and progressing through potentially malignant oral disorders to oral squamous cell carcinoma(OSCC).The section on OSCC reflects recent information on epidemiology,pathogenesis,and histological prognostic factors.Noteworthy is the specific categorization of verrucous carcinoma(VC)and carcinoma cuniculatum(CC),both associated with the oral cavity and distinct in clinical and histologic characteristics.This classification adjustment emphasizes the oral cavity as their predominant site in the head and neck.Designating specific sections for VC and CC aims to provide comprehensive insights into these unique subtypes,elucidating their clinical features,distinct histological characteristics,prevalence,significance,and clinical relevance.By categorizing these subtypes into specific sections,the 5th edition of the WHO classification aims to provide a more nuanced and detailed account,enhancing our understanding of these specific variants within the broader spectrum of head and neck tumors.

Reconstruction surgery in head and neck cancer patients amidst the COVID-19 pandemic:Current practice and lessons for the future

The coronavirus disease 2019(COVID-19)pandemic has imposed a radical change in daily life and work routine.In this context,health systems have suffered important and serious repercussions in all fields.Among the changes brought about by the state of global health emergency,adjustments to guidelines,priorities,structures,professional teams,and epidemiological data stand out.In light of this,the oncological field has witnessed several changes in the approach to cancer,whether due to delay in diagnosis,screening deficit,personnel shortage or the psychological impact that the pandemic has had on cancer patients.This article focuses on the management of oral carcinoma and the surgical approaches that oral and maxillofacial specialists have had at their disposal during the health emergency.In this period,the oral and maxillofacial surgeons have faced many obstacles.The proximity of maxillofacial structures to the airways,the need of elective and punctual procedures in cancerous lesions,the aggressiveness of head and neck tumors,and the need for important healthcare costs to support such delicate surgeries are examples of some of the challenges imposed for this field.One of the possible surgical'solutions'to the difficulties in managing surgical cases of oral carcinoma during the pandemic is locoregional flaps,which in the pre-COVID-19 era were less used than free flaps.However,during the health emergency,its use has been widely reassessed.This setback may represent a precedent for opening up new reflections.In the course of a long-term pandemic,a reassessment of the validity of different medical and surgical therapeutic approaches should be considered.Finally,given that the pandemic has highlighted vulnerabilities and shortcomings in a number of ways,including the issues of essential resource shortages,underinvestment in public health services,lack of coordination and versatility among politicians,policymakers and health leaders,resulting in overloaded health systems,rapid case development,and high mortality,a more careful analysis of the changes needed in different health systems to satisfactorily face future emergencies is essential to be carried out.This should be directed especially towards improving the management of health systems,their coordination as well as reviewing related practices,even in the surgical field.

Factors influencing comfort level in head and neck neoplasm patients receiving radiotherapy

Objective:To determine factors that influence comfort in head and neck neoplasm patients receiving radiotherapy.Methods:In total,200 head and neck neoplasm patients receiving radiotherapy were recruited from three tertiary first class hospitals.They were assessed by Radiotherapy Comfort Questionnaire for patients with head and neck neoplasm,Social Support Scale,and Medical Coping Modes Questionnaire.Results:The total score of comfort was 60.54±8.32.Multiple linear regression analysis indicated that number of radiation treatments,family accompaniment,educational level,resignation coping mode,complications due to diabetes,accompanying chemotherapy,and the utilization of social support significantly influenced comfort level(p<0.05).Among these,number of radiation treatments,complications due to diabetes,accompanying chemotherapy,and resignation coping were negative factors.Conclusion:Encouraging utilization of social support systems and a positive coping mode is important for increasing comfort level in head and neck neoplasm patients during radiotherapy.Nurses should pay particular attention to those patients during later stages of radiotherapy or chemotherapy,with diabetes,without family accompaniment,and with lower education level.

Targeting head and neck tumoral stem cells： From biologicalaspects to therapeutic perspectives

Head and neck squamous cell cancer(HNSCC) is the sixth most common cancer in the world. Effective therapeutic modalities such as surgery, radiation, chemotherapy and combinations of each are used in the management of the disease. In most cases, treatment fails to obtain total cancer cure. In recent years, it appears that one of the key determinants of treatment failure may be the presence of cancer stem cells(CSCs) that escape currently available therapies. CSCs form a small portion of the total tumor burden but may play a disproportionately important role in determining outcomes. CSCs have stem features such as self-renewal, high migration capacity, drug resistance, high proliferation abilities. A large body of evidence points to the fact that CSCs are particularly resistant to radiotherapy and chemotherapy. In HNSCC, CSCs have been increasingly shown to have an integral role in tumor initiation, disease progression, metastasis and treatment resistance. In the light of such observations, the present review summarizes biological characteristics of CSCs in HNSCC, outlines targeted strategies for the successful eradication of CSCs in HNSCC including targeting the self-renewal controlling pathways, blocking epithelial mesenchymal transition, niche targeting, immunotherapy approaches and highlights the need to better understand CSCs biology for new treatments modalities.

Clinical Investigation of ^(99m)Tc-MIBI Imaging in Head and Neck Tumors

Objective： To investigate the diagnostic potential value of ^99Tc-MIBI imaging in head and neck tumors. Methods： Ninety-one patients with malignant and benign head and neck lesions were subjected to ^99mTc-MIBI tomography, and 20 healthy volunteers served as control group. Results： The overall sensitivity,specificity, accuracy and positive predictive accuracy of early/delay ^99mTc-MIBI imaging in diagnosis of head and neck malignant tumors were 78.7%/72.3%, 72.1%/88.4%, 75.6%/80.0% and 75.5%/87.2% respectively. The results of ^99mTc-MIBI Imaging in diagnosis of nasopharyngeal cancer and sinonasal non-Hodgkin＇s lymphoma were more satisfactory than those in maxillary sinus cancer. In distinguishing recurrent/residual nasopharyngeal carcinoma and sinonasal non-Hodgkin＇s lymphoma, ^99mTc-MIBI scintigraphy was superior to CT/MRI. Conclusion： ^99mTc-MIBI imaging is a promising useful tool in identifying head and neck tumor, and it has a special value to evaluate the local invasion and metastasis involved.

Reliability and validity of the Chinese version of the Head and Neck Information Needs Questionnaire for patients with head and neck cancer and their caregivers

Objectives:This study aimed to assess the reliability and validity of the Chinese version of the Head and Neck Information Needs Questionnaire(HaNiQ).Methods:The HaNiQ was translated into a Chinese version using internationally recognized forwardand back-translation procedures.The reliability and validity of the HaNiQ were measured using Cronbach’s a coefficient,split-half reliability,exploratory factor analysis,and Pearson correlation analysis.Results:A total of 207 patients in different head and neck cancer(HNC)stages and 174 caregivers completed the Chinese version of the HaNiQ.Internal consistencies varied between good and very well(Cronbach’s α coefficient 0.74-0.90);the split-half coefficient and the content validity index(CVI)of the questionnaire were 83.5%and 83.33%,respectively.The cumulative contribution rates of the 5 subscales in patients with HNCand their caregivers were 62.41%and 61.19%,respectively.However,there are some differences between the Chinese questionnaire for caregiver and the original questionnaire regarding the attribution of items.Items 22,23,and 27 in the Psychosocial subscale of the English version were assigned to the Survivorship subscale in the Chinese version for caregivers.Conclusions:The results demonstrated that the Chinese version of the HaNiQ is a reliable and valid instrument for measuring the information needs of patients with HNC and that of their caregivers.Though the structure of the Chinese versionwas different from the English version for caregivers of HNC patients,the Chinese version of the HaNiQ appears to be reliable and would benefit from further testing.

Restricting carbohydrates to fight head and neck cancer——is this realistic?

Head and neck cancers(HNCs) are aggressive tumors that typically demonstrate a high glycolytic rate, which results in resistance to cytotoxic therapy and poor prognosis. Due to their location these tumors specifically impair food intake and quality of life, so that prevention of weight loss through nutrition support becomes an important treatment goal. Dietary restriction of carbohydrates(CHOs) and their replacement with fat, mostly in form of a ketogenic diet(KD), have been suggested to accommodate for both the altered tumor cell metabolism and cancer-associated weight loss. In this review, I present three specific rationales for CHO restriction and nutritional ketosis as supportive treatment options for the HNC patient. These are(1) targeting the origin and specific aspects of tumor glycolysis;(2) protecting normal tissue from but sensitizing tumor tissue to radiation- and chemotherapy induced cell kill;(3) supporting body and muscle mass maintenance. While most of these benefits of CHO restriction apply to cancer in general, specific aspects of implementation are discussed in relation to HNC patients. While CHO restriction seems feasible in HNC patients the available evidence indicates that its role may extend beyond fighting malnutrition to fighting HNC itself.

Rupture of carotid artery pseudoaneurysm in the modern era of definitive chemoradiation for head and neck cancer:Two case reports

BACKGROUND Carotid blowout syndrome(CBS)is a rupture of the carotid artery and is mainly caused by radiation and resection of head and neck cancers or direct tumor invasion of the carotid artery wall.It is a life-threatening clinical situation.There is no established and effective mode of management of CBS.Furthermore,there is no established preceding sign or symptom;therefore,preventive efforts are not clinically meaningful.CASE SUMMARY We described two cases of CBS that occurred in patients with head and neck cancer after definitive chemoradiotherapy(CRT)using three-dimensional conformal intensity-modulated radiation therapy.Two men aged 61 and 56 years with locally advanced head and neck cancer were treated with definitive CRT.After completing CRT,both of them achieved complete remission.Subsequently,they had persistent severe pain in the oropharyngeal mucosal region and the irradiated neck despite the use of opioid analgesics and rehabilitation for relief of contracted skin.However,continuous follow-up imaging studies showed no evidence of cancer recurrence.Eleven to twelve months after completing CRT,the patients visited the emergency room complaining about massive oronasal bleeding.Angiograms showed rupture of carotid artery pseudoaneurysms on the irradiated side.Despite attempting to secure hemostasis with carotid arterial stent insertion and coil embolization,both patients died because of repeated bleeding from the pseudoaneurysms.CONCLUSION In patients with persistent pain in irradiated sites,clinicians should be suspicious of progressing or impending CBS,even in the three-dimensional conformal intensity-modulated radiation therapy era.

Evaluation of Quality of Life and Oral Changes of Patients in Head and Neck Radiotherapy: Observational Study

Radiotherapy (RT) in the head and neck, despite coming from technological evolution, is challenged by the acute and late side effects of local irradiation, including permanent loss of saliva, osteoradionecrosis, dental caries induced by radiation and necrosis of the oral cavity, mucositis, xerostomia and secondary infections like candidiasis. Since these manifestations are limiting and the integrity of the vital organs contemplates the patient’s general health status, the oral health-related quality of life (OHRQoL) can be significantly affected by the treatment of head and neck cancer (HNC), since cancer can cause important changes in vital functions related to communication, food and social contact, causing disturbances in the patient’s life. An observational and longitudinal study was carried out with 16 cancer patients submitted to RT in the head and neck, between the years 2019-2020 with the objectives of collecting clinical and epidemiological data on the main oral changes caused by RT in the head and neck and correlating them with the impact on OHRQoL. To analyze the OHRQoL, the University of Washington’s Quality of Life Assessment questionnaire (UW-QOL) was applied once a week for 4 weeks and to observe oral manifestations, a dental clinic file standardized by the researchers was applied. The main oral manifestations clinically observed were hyposalivation, trismus and oral mucositis. The UW-QOL presented pain, chewing and taste as the main complaints reported by patients, however, appearance, salivation and chewing showed statistically significant differences over the weeks. The main manifestations observed were hyposalivation, trismus and oral mucositis, the physical limitations resulting from these manifestations impact the OHRQoL of cancer patients in terms of appearance, salivation and chewing.
