RESUMO
PURPOSE: A deterioration of the general condition, a prolonged fever or an unexplained inflammatory syndrome are frequent reasons for hospitalization in a internal medicine unit. In these situations, it is not rare to make a diagnosis of cancer. PATIENTS AND METHODS: A descriptive study was carried out over a three years period (1st October 1999 to 30th September 2002) in an internal medicine unit. Every week, all patients in whom a cancer was diagnosed were enrolled in the study. RESULTS: During this period, 165 patients were identified (3.8% of the in-patients). A histological proof was obtained in 114 patients. Digestive and bronchopulmonary cancers were the most frequent. The first signs were very varied but digestive disorders and ferriprive anaemia were the most frequent. The number of investigations necessary to diagnosis were weak (1.56 procedures) when a sign was identified but were high (5.12 procedures) when no information was provided by interview, clinical examination or usual biological tests. CONCLUSION: Diagnosis of cancer is an usual situation in an internal medicine unit. Interview and clinical examination are essential in the diagnostic step. It could decrease the number of procedures. Internal unit services are fully concerned by the announcement of cancer.
