Photodynamic therapy of laryngeal cancers
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...
متن کاملPhotodynamic Therapy for Non-Melanoma Skin Cancers
Non-melanoma skin cancer (NMSC) is traditionally treated with surgical excision. Nonsurgical methods such as cryotherapy and topical chemotherapeutics, amongst other treatments, are other options. Actinic keratosis (AKs) are considered precancerous lesions that eventually may progress to squamous cell carcinoma (SCC). Photodynamic therapy (PDT) offers an effective treatment for AKs, and is also...
متن کاملPhotodynamic Therapy in Advanced Tracheobronchial Cancers
Photodynamic therapy (PDT) has been introduced in the early eighties for treating patients with malignancies in the tracheobronchial tract. After intravenous injection of the photosensitizers, the tumor area in the tracheobronchial tree is illuminated bronchoscopically using a laser fiber to transmit light of a specific wavelength during the procedure. Secondary tissue necrosis ensues, because ...
متن کاملPhotodynamic Therapy in Non-Gastrointestinal Thoracic Malignancies
Photodynamic therapy has a role in the management of early and late thoracic malignancies. It can be used to facilitate minimally-invasive treatment of early endobronchial tumours and also to palliate obstructive and bleeding effects of advanced endobronchial tumours. Photodynamic therapy has been used as a means of downsizing tumours to allow for resection, as well as reducing the extent of re...
متن کاملPhotodynamic Therapy for Sun Damage and Skin Cancers
Photodynamic therapy (PDT) is a medical treatment that uses a photosensitizing drug (a drug that becomes activated by light exposure) and a light source to activate the applied drug. The result is an activated oxygen molecule that can destroy nearby cells. Precancerous cells and certain types of cancer cells can be treated this way. The procedure is easily performed in a physician's office or o...
