Carcinoma of unknown primary in the head and neck: The evaluation of the effectiveness of XXXX -PET/CT, own experience.

@entity1 @entity419 @entity5 @entity957 @entity751 @entity3
AIM: The aim of the present study was to estimate the clinical effectiveness of @entity419 -PET/CT in the detection of the @entity5 in @entity1 with histologically proven @entity957 cervical lymph nodes @entity3 from an unknown primary. BACKGROUND: @entity419 positron emission tomography combined with CT ( @entity419 -PET/CT) is believed to be very helpful in localization of @entity5 in @entity751 @entity1 . MATERIAL AND METHOD: 41 @entity1 referred to Poznan Medical University Department of Head and Neck Surgery from January 2010 to December 2013 with @entity751 were included in the study. All @entity1 presented fine-needle biopsy proven @entity957 @entity3 of the upper-, or mid neck lymph nodes. The final results were obtained from the histopathologic reports of tissue samples from anatomical regions suspected for @entity5 , additional imaging exams as well as clinical follow-up data. RESULTS: The @entity419 -PET/CT successfully detected @entity5 in 7 out of 41 @entity1 (17%). In two more cases the @entity5 was indicated in the lung. 24 of 41 @entity1 (58.5%) analyzed in our study remained without evidence of a @entity5 . In 4 cases (9.75%) we did not reveal any pathology within the localizations indicated by PET/CT on panendoscopy. In 4 cases we obtained histological confirmation of @entity5 on panendoscopy despite the negative results of PET/CT examinations. CONCLUSION: We may suppose a relatively high usefulness of @entity419 -PET/CT in the diagnosis process of @entity751 @entity1 . High NPV may indicate @entity1 with no symptoms of @entity5 , which allows to avoid extensive resection or extra imaging.
