BACKGROUND: The head and neck tumours are a heterogeneous group of diseases that affect the otolaryngology (ENT) sphere . It constitutes 2.9% of all new cancer cases. Predominantly affect older men aged 40 years. Smoking, excessive alcohol consumption, treatment with high doses of corticosteroids and malnutrition suffering after surgery and radiotherapy, involves a potential situation of accelerated bone loss in a young population with good long-term prognosis. OBJECTIVE: To describe the characteristics regarding risk factors and osteoporotic disease in patients with head and neck tumours. MATERIAL AND METHODS: An Observational study of a case series of patients with tumours of the head and neck joint monitoring in consultations of Rheumatology and Medical Oncology Hospital Valme area. We collected the following variables; age, sex, risk factors for osteoporosis and osteoporotic fracture,lateral radiography of lumbar and thoracic spine, and lumbar spine and hip bone densitometry RESULTS: 50 patients diagnosed whith head and neck tumours were included. Of these, 100% were male, with a mean age of 62 years at present. The most frequent location was the larynx in 55% of cases, followed by a 7% for those of tonsils and other locations of the oral cavity . Approximately a 16% of patients had a history of gastrointestinal pathologyIn relation to risk factors for both disease, tumour and osteoporosis we found :(Table is included in full-text article.)Also found two patients with vertebral fractures, one with osteoporosis and the second with osteopenia.Finally in relation to tumour pathology, 10% were stage II, candidates for treatment with radiation therapy compared with 90% remaining subsidiary of intensive treatment with chemotherapy, radiation therapy and high-dose corticosteroids. CONCLUSIONS: In our sample, we found that up to 16.6% of patients and 7.1% had osteopenia or osteoporosis at baseline. Assuming that during treatment, they will suffer about 16% of loss weight, attached to treatment with high-dose corticosteroids, would justify develop measures for primary prevention of osteoporosis with a study and treatment of these patients.
