Survival trends of patients with oral and oropharyngeal cancer treated at a cancer center in São Paulo, Brazil

CONCLUSION: Survival across the two time periods remained stable for oral SCC but showed a significant increase for oropharyngeal SCC, possibly because of improvements in the patients ’ response to radiotherapy, such as intensity-modulated radiation therapy, and the use of more accurate diagnostic imaging approaches.

AbstractPurposeOur aim is to determine the impact of the size of ROI in detecting subcentimeter metastatic lymph nodes in patients with head and neck squamous cell carcinoma (HNSCC). Secondary aim is to determine the impact of the histopathologic grade of the primary cancer on the ADC value of the metastatic nodes.MethodsThe prospective study included 51 patients with histopathologically proven HNSCC at the primary site. Primary site includes oral cavity, oropharynx, larynx, and hypopharynx. ADC values of the lymph nodes were measured on ADC maps by placing two ROIs in the lymph nodes (0.2 cm2 in the center of the node and...

Abstract The head and neck squamous cell carcinoma (HNSCC) is an aggressive human malignancy diagnosed in more than 800 000 new cases worldwide, and mostly arises in the oral cavity, oropharynx, larynx, hypopharynx, and nasopharynx. The study presented here aimed to determine a possible association of rs11515 and rs3088440 gene polymorphisms in the CDKN2A gene (cyclin dependent kinase inhibitor 2A), as well as rs769412 and rs937283 in the MDM2 gene (murine double minute 2), with oral cavity cancer in a sample of Polish population; CDKN2A is crucial in regulating the cell cycle while MDM2 is an oncogene invo...

Conclusion: Head and neck cancers are the third most common cancer in Bhutan after stomach cancer and cervical cancer. Thyroid, oral cavity and hypopharynx are the top three anatomical sites for head and neck cancers in Bhutan. The current epidemiological and histopathological profile of head and neck cancers will form a baseline of information and basis for further research on head and neck cancers in Bhutan.

o Muto Ionna : Head and neck squamous cell carcinomas (HNSCCs) are a very heterogeneous group of malignancies arising from the upper aerodigestive tract. They show different clinical behaviors depending on their origin site and genetics. Several data support the existence of at least two genetically different types of HNSCC, one virus-related and the other alcohol and/or tobacco and oral trauma-related, which show both clinical and biological opposite features. In fact, human papillomavirus (HPV)-related HNSCCs, which are mainly located in the oropharynx, are characterized by better prognosis and response to ther...

The objective of this study was to evaluate the influence of clinical-pathological and sociodemographic factors on the prevalence of distant metastasis (DM) and overall survival in patients with oral cavity and oropharynx squamous cell carcinoma (OOSCC). MATERIAL AND METHODS: Cross-sectional study based on the records of 404 OOSCC patients evaluated for DM, covering the period 2000-2014. We analysed the influence of age, sex, level of schooling, primary tumor subsite, treatment, marital status, family history of cancer, history of smoking and alcohol consumption, type of health care coverage (private vs. public) and ov...

Abstract BACKGROUND AND PURPOSE: Bilateral elective nodal irradiation (ENI) remains the standard treatment for head and neck squamous cell carcinoma (HNSCC). Unilateral ENI could reduce treatment toxicity and improve health-related quality-of-life (HRQOL). This prospective proof-of-principle trial (NCT02572661) investigated the feasibility, safety and clinical benefits of SPECT/CT-guided ENI of the node-negative contralateral neck. MATERIALS AND METHODS: Patients with lateralized T1-3N0-2bM0 HNSCC of the oropharynx, oral cavity, larynx and hypopharynx underwent SPECT/CT after peritumoral 99mTc-nanocolloid inj...

The aim of this ongoing study was to examine Quality of Life (QoL) and pain in the first three months after trans-oral robotic surgery (TORS). Results will be available in November 2019. With the rising incidence of Human Papilloma Virus (HPV) induced oropharyngeal squamous cell carcinoma (OPSCC) this cancer has become the most frequently diagnosed head and neck cancer world-wide. Currently there are two main treatment options: radiotherapy (with or without chemotherapy) and TORS. TORS is still a relatively new treatment modality (approved by the FDA in 2000) and more research into outcomes, particularly functional and QoL outcomes is needed.
