[Neck metastases from unknown primary neoplasms (CUP syndrome)].
Carcinoma of unknown primary (CUP-syndrome) is taken into consideration when the patient has histologically confirmed metastases but the primary focus remains unknown or it's diagnosis is delayed. Metastases of unknown origin constitute from 5% to 31% of all neck metastases. Squamous cell carcinoma and anaplastic carcinoma metastases in the neck lymphatics suggest that location of primary focus can be found in head and neck region. Diagnostic procedures applied in detection of primary foci have been described. The knowledge of lymphatic metastases spreading routes is helpful in the primary focus detection. In the material of 1348 patients treated oncologically in the years 1991-1997 in ENT Department of Karol Marcinkowski University of Medical Sciences in Poznań, 22 were diagnosed for CUP syndrome. Primary foci were not found in 7 cases. In the remaining 15 patients the primary was located in nasopharynx, palatinal tonsil, tongue, hypopharynx, testes or breast. The treatment included the radical neck dissection with consecutive irradiation and/or chemotherapy, and in the case of diagnosing the primary one applied it's radical removal or radiotherapy.
