Introduction: Radiation therapy involves a multistep procedure; therefore, the error in patient set up is an inherent part of the treatment. Main purpose of this study was to determine the clinical target volume (CTV) to planning target volume (PTV) in head and neck cancer patients. Material and Methods: A total of 15 patients who had daily p...

introduction: her2/neu, a member of the epidermal growth factor receptor family, has been shown to be over-expressed in some tumors. the purpose of this study was to determine the salivary levels and tissue expression of her2/neu in patients with head and neck squamous cell carcinoma (hnscc) and their correlation with clinicopathologic parameters.   materials and methods: enzyme-linked immunoso...

PURPOSE OF REVIEW Head and neck lymphedema (HNL) is a common and often debilitating cancer treatment effect that is under-researched and ill defined. We examined current literature and reviewed historical treatment approaches. We propose a model for evaluation and treatment of HNL used at The University of Texas M. D. Anderson Cancer Center (MDACC) for patients with head and neck cancer (HNC). ...

BACKGROUND The role of complementary and alternative medicine (CAM) in cancer treatment is controversial. The aim of the study was to assess whether CAM use was associated with a delay in the initiation of conventional cancer treatment for head and neck cancer. METHODS CAM usage data were collected by mailed questionnaire for 149 incident head and neck cancer patients who were identified thro...

BACKGROUND Epidemiological association of head and neck cancer with smokeless tobacco (ST) emphasizes the need to unravel the molecular mechanisms implicated in cancer development, and identify pharmacologically safe agents for early intervention and prevention of disease recurrence. Guggulsterone (GS), a biosafe nutraceutical, inhibits the PI3K/Akt pathway that plays a critical role in HNSCC d...

There are few data focusing on postoperative course after major head and neck cancer surgery in the elderly compared with the younger population. The aim of this study was to assess the impact of age on postoperative outcomes. At hospital admission, we prospectively collected data from 261 patients separated into two groups with regard to their age (those >or= 70 years and those < 70 years). Tw...

Background:The incidence rate of head and neck cancer in the world is about 560,000 new cases a year. Larynx cancer is the most common malignancy in head and neck in Iran. The most common head and neck carcinoma is the malignancy of squamous epithelial cells. This study was conducted to determine the survival rate of patients undergoing nonsurgical treatment methods for larynge...

PURPOSE This study of relatives to patients with head and neck cancer (HNC) treated with radiotherapy describes how the relatives experienced the patient's situation, especially with respect to pain, and how the relatives themselves experienced the situation. METHODS Semi-structured interviews of 21 relatives to HNC patients who suffered from pain were conducted, and a qualitative content ana...

We presented 9 recurrent head and neck carcinoma patients. Priorly all of them had received radiochemotherapy. We used cetuximab and irradiation concomitantly. Overall survival analysis of the patients was performed using the Kaplan-Meier method on SPSS version 15.0. Based on this calculation, mean follow-up duration is 12.8 months. Mean survival time is 19.8 months and annual mean survival rat...
