Morphological modifications of vocal anatomy are widespread among vertebrates, and the investigation of the physiological mechanisms and adaptive functions of such variants is an important focus of research into the evolution of communication. The "descended larynx" of adult humans has traditionally been considered unique to our species, representing an adaptation for articulate speech, and deb...
The clinical and pathological findings in three patients with clear cell carcinoma of the larynx are described. This type of neoplasm in the larynx is extremely rare. The aggressiveness of the tumour and its high biological malignancy are stressed.
BACKGROUND Chemotherapy with cisplatin (P) and 5-fluorouracil (F) followed by radiotherapy in patients who respond to chemotherapy is an alternative to total laryngectomy for patients with locally advanced larynx and hypopharynx cancer. Data suggest that docetaxel (T) may add to the efficacy of PF. The objective of this trial was to determine whether adding T to PF could increase the larynx pre...
Carcinoma of the larynx accounts for 25-30 percent of all carcinomas of the head and neck. Early carcinomas of the larynx (Tis or T1) and severe dysplasia are presently treated with either radiation therapy or surgery alone. Radiation therapy, however, has significant disadvantages including mucositis during and for potential prolonged periods after therapy, permanently altered voice quality, d...
BACKGROUND Tobacco smoking and alcohol drinking generate oxidative DNA damage and may contribute to larynx carcinogenesis. The X-ray repair cross complementing 1 (XRCC1) and excision repair cross-complementing rodent repair deficiency, complementation group 4 (ERCC4(XPF)) genes are important components of DNA excision repair systems, which repair DNA damage induced by various factors, including...
