Angiogenesis is a necessary process for tumor growth, progression and diffusion. In the last years many efforts have been made to understand the mechanisms necessary to the formation of new vessels in tumor tissue and how to integrate these findings in the treatment of different type of cancer. Thanks to these studies there are today many anti-angiogenic drugs with established activity in cance...
OBJECTIVE To determine associations between objective assessments (swallowing function and weight change) and subjective quality-of-life (QOL) measures. DESIGN Observational case series using clinical testing and questionnaires. SETTING University hospital-based tertiary clinical practice. PATIENTS Convenience sample of 5-year survivors of head and neck cancer (62 nonlaryngectomy survivor...
Introduction: Synovial sarcoma makes up 8–10% of all soft tissue sarcomas, and constitutes 3–10% of all sarcomas occurring in the head and neck region.

Case Report: A 51-year-old gentleman presented with right-sided neck swelling which had been progressively increasing in size for the past 2 years. A computed ...
Aggressive fibromatosis also known as extra abdominal desmoid tumor is an uncommon benign tumor of soft tissue origin with fibroblastic proliferationSince the tumor is locally aggressive, the lesion may be misdiagnosed as low -grade fibrosarcoms. It accounts for 0.03% - 0.1% of all body tumors and 3% of all soft tissue tumors. Only 10% to 15% of these lesions occur in head and neck, usually in ...

In recent decades, radiotherapy has been had a fundamental role in the treatment of cancers. The tumor control probability (TCP) and lowest risk in normal tissue is the aim of radiotherapy techniques. The radiation sensitivity of thyroid glands increases cancer risk of scattering radiation and induces hypothyroidism. In this study, the average thyroid dose due to head and neck radiotherapy in t...
BACKGROUND: Head and neck cancer is one of the six most prevalent neoplasms worldwide. Regardless of tumor site, deterioration of basic functions affecting head and neck areas are perceived and affect patients' lives. The aim of this study was to evaluate quality of life (Short Form) and oral health related quality of life (OHIP-14) in patients with head and neck cancer. METHODS: This study was...
Approximately 15% of sogt-tissue sarcomas occur in head neck area and sarcma should be considered in the differential diagnosis of any tumor mass in this anatomic region, especially in younger patient. This was a retrospective study that reviewed all head and neck sarcoma cases registered at Imam Khomeini Hospital and Cancer Institute during the period 1987-1996. Using medical records, relevant...
