Head and neck cancer: new trends in research and clinical practice.

Head and neck cancer represents an interesting subject of research in the third millennium. Apart from basic research (molecular biology, genic therapies etc.) which it shares with other neoplasms, a number of studies are in progress in the field of clinical research. In particular trials of combined radiation and chemotherapy with one or several drugs are being carried out and they will certainly provide definitive results in the field of clinical application. Further acquisitions will be provided by the studies on non conventional dose fractionation and the application of intensity modulated radiotherapy. Finally, the first studies on chemoprevention in patients with malignant or precancerous lesions of the head and neck will be soon concluded.

Advances in the treatment of lung cancer: economic and organizational aspects.

The organizational optimization in radiotherapy tends to a correct balance of quality of service and containment of health care expenditure; this goal is necessarily correlated with the real potentialities available to each center while considering the possible clinical benefits for the patient. In lung cancer, outcomes achieved with radiation therapy are encouraging in terms of local control and survival when treatment is performed with the available modern technology whose costs from an exclusively economic analysis are shown to be still quite high. In an assessment focused on clinical outcomes, better local control, higher survival and improved quality of life represent tangible benefits: this has a positive impact on community costs and may represent a high priority goal for health care providers, yielding a benefit that can be quantified with the most recent analyses of health care economy.
