The NRC (National Research Council) task force on head and neck cancer issued this document to help clinicians involved in diagnosing and treating precancerous oral diseases. Chapter 1 includes definition, epidemiology, risk factors (alcohol, smoking, poor oral hygiene), WHO classification, clinical picture of leukoplakias, erythroplasia, lichen planus, as well as their natural history. Chapter 2 points out the clinical signs to be looked for in order to make a proper diagnosis and discusses biopsy techniques. Chapter 3 deals with therapeutic procedures (surgical technique and medical treatment), while Chapter 4 concerns follow-up according to the clinical and histological diagnosis. Finally, some statistical forms are enclosed: Form 1 consists of information regarding educational qualifications, occupation, alcohol consumption, smoking and dietary habits; Form 2 consists of information about previous diseases and the history of the present disease; Form 3 records the signs and symptoms observed for the precancerous lesion; Form 4 records treatment modalities; Form 5 records patient follow-up.

Head and neck squamous cell carcinoma of the (HNSCC) represents approximately 5% of malignant tumours in Italy. HNSCC are commonly treated with surgery or radiotherapy, or a combination of such therapies. The objectives of treatment are maximum cure rate balanced with organ preservation, restoration of form and function, reduction of morbidities and improvement or maintenance of the patient's quality of life. Immediate reconstructive surgery: local, regional or free flaps are now widely advised in the treatment of these patients. Microsurgical transfer requires expertise, is time and resource consuming, and as a whole requires substantial costs. These considerations introduce some concerns about the wide or indiscriminate use of free flap reconstructive surgery. When considering cost-benefit outcomes of such treatment, the main objective is undoubtedly, survival. This data is underreported in the current literature, whereas functional outcomes of free flaps have been largely diffused and accepted. This study collects data from 1178 patients treated with free flap reconstructive surgery following ablation of HNSCC in a group of Italian tertiary hospitals, all members of the HeadNeck Group affiliated with the Italian Society of Microsurgery. According to many authors, free flap surgery for HNSCC seems to be a beneficial option for treatment even in terms of survival.I tumori spinocellulari del distretto Cervico Facciale rappresentano circa il 5% dei tumori maligni in Italia. Essi sono comunemente trattati con chirurgia o radioterapia, o entrambi le terapie. La ricostruzione rappresenta un momento fondamentale della terapia nel rispetto della qualità di vita di questi pazienti. La microchirurgia ricostruttiva rappresenta la tecnica che offre i migliori risultati funzionali ma è oggetto di discussione in un rapporto costo-benefici. In questo lavoro sono raccolti ed analizzati i dati di 1178 pazienti provenienti dai membri del gruppo testa e collo, affiliato alla società Italiana di Microchirurgia, e i cui dati sono rapportati primariamente alla sopravvivenza.
