The case report is important because of the rare diagnosis and the challenge we faced in the diagnosis and treatment of the pat...

The optimal fractionation schedule for radiotherapy of head and neck cancer has been controversial. The objective of this randomized trial was to test the efficacy of hyperfractionation vs. standard fractionation. Patients with squamous cell carcinoma of head and neck organs were randomly assigned to receive radiotherapy delivered with A) standard fractionation at 2 Gy/fraction/day, 5 days...

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.
