A low modulation factor (MF) maintaining a good dose distribution contributes to the shortening of the delivery time and efficiency of the treatment plan in helical tomotherapy. The purpose of this study was to reduce the delivery time using initial values and the upper limit values of MF. First, patients with head and neck cancer (293 cases) or prostate cancer (181 cases) treated between June 2011 and July 2015 were included in the analysis of MF values. The initial MF value (MFinitial ) was defined as the average MFactual value, and the upper limit of the MF value (MFUL ) was defined according the following equation: MFUL = 2 × standard deviation of MFactual value + the average MFactual Next, a treatment plan was designed for patients with head and neck cancer (62 cases) and prostate cancer (13 cases) treated between December 2015 and June 2016...

Background: Over-expression of p16INK4a protein is a biomarker for human papillomavirus (HPV)-associated cervical cancer. However, absence of p16INK4a protein expression in HPV-associated cancer of the oral cavity and oropharynx has been reported. Among a number of possible reasons for this is methylation, which is frequently noted in the promoter region of p16INK4a and is associated with silencing of the gene and disease severity. Methods: We investigated the relationships between p16INK4a protein expression, HPV infection and methylation status of the p16INK4a promoter in cancers of the oral cavity and oropharynx...

Human papillomavirus type 16 (HPV16) is the major cause of cervical cancer and of a fraction of oropharyngeal carcinoma. Few studies compared the viral expression profiles in the two types of tumor. We analyzed HPV genotypes and viral load as well as early (E2/E4, E5, E6, E6*I, E6*II, E7) and late (L1 and L2) gene expression of HPV16 in cervical and oropharyngeal cancer biopsies. The study included 28 cervical squamous cell carcinoma (SCC) and ten oropharyngeal SCC, along with pair-matched non-tumor tissues, as well as four oropharynx dysplastic tissues and 112 cervical intraepithelial neoplasia biopsies...

BACKGROUND: Planned neck dissection (ND) after radical chemoradiotherapy (CRT) for locally advanced nodal metastases in patients with head and neck squamous cell carcinoma (HNSCC) remains controversial. Thirty per cent of ND specimens show histological evidence of tumour. Consequently, a significant proportion of clinicians still practise planned ND. Fludeoxyglucose positron emission tomography (PET)-computerised tomography (CT) scanning demonstrated high negative predictive values for persistent nodal disease, providing a possible alternative paradigm to ND...

Incidence rates of head and neck cancers (HNC) associated with human papillomavirus (HPVa) infection are increasing while non-HPV-associated (non-HPVa) HNC cancer rates are decreasing. As nearly all sexually active individuals will acquire an HPV infection, it is important to understand epidemiologic trends of HNCs associated with this sexually transmitted disease. We analyzed SEER 9 (1973-2012) and 18 data (2000-2012) for HPVa HNCs (oropharynx area; OP) and non-HPVa (oral cavity area; OC). Incidence rates were examined by gender, race, rurality, geographic location, and time...

Introduction Concurrent chemoradiation is the standard of care in inoperable locally advanced squamous cell head and neck cancers. The most widely accepted schedule of concomitant cisplatin is 100mg/m(2) given on a 3 weekly basis but the optimal regime is unknown. Objective The objective of this study is to assess the tolerability, compliance, and clinical outcomes of weekly cisplatin (40mg/m(2)). Methods During the period of January 2007-December 2009, we analyzed retrospectively 122 patients with histologically proven squamous cell carcinoma of head and neck (nasopharynx, oropharynx, larynx, hypopharynx, and oral cavity) treated with definitive chemoradiation...

Mucosal high-risk (HR) human papillomaviruses (HPV) cause a subset of head and neck cancers (HNC). The HPV-attributable fraction of HNC varies substantially between countries. Although HNC has a very high incidence in the Indian sub-continent, information on the contribution of HPV infection is limited. Here, we evaluated the HPV-attributable fraction in HNC (N=364) collected in a central region of India. HNC from three different anatomical subsites were included, namely oral cavity (n=252), oropharynx (n=53) and hypopharynx/larynx (n=59)...

Raynaud's of the tongue following radiation alone or chemoradiotherapy (CRT) is a rare occurrence. The present study reports a case where typical symptoms and signs of Raynaud's phenomenon involving the tongue occurred ~18 months following CRT treatment in a 53-year-old female, who was a smoker prior to CRT with stage T2N2cM0 local-regional advanced stage IV oropharyngeal cancer. The patient was treated using cisplatin chemotherapy and intensity-modulated radiation with a dose of 70 Gray (Gy). The intermittent episodes of painful discoloration of the tongue were exacerbated due to the cold and emotional stress...
