[Palliative chemotherapy and CUP-syndrome: medical intentions versus patients' attitudes in decision making].

The following case report is about a 55 year old male patient with CUP-syndrome. After developing a malignant bowel obstruction he received five cycles of a palliative chemotherapy with oxaliplatin and irinotecan. The focus is on medical intentions and goals concerning palliative chemotherapy and on discussing patients' attitudes towards chemotherapy. Communication is identified as fundamental skill in shared decision making. On the one hand it improves Patients' satisfaction and palliative care and on the other hand it reduces psychological and existential suffering. In tumors of unknown primary site regimens with different combinations of Platin, Taxol, Etoposide, Irinotecan and Gemcitabine showed responses up to 46% and a survival benefit with an overall median survival up to 12 months and even long term survival.
