The benefit of abdominal sonography and chest X-ray for staging XXXX in stages UICC I and II.

@entity1 @entity5 @entity957 @entity3 @entity204
PURPOSE: The purpose of this study was to evaluate how often distant @entity3 occur in localized @entity957 ( @entity957 ). The investigators hypothesize that abdominal sonography and chest X-ray may not be necessary for initial staging of early @entity957 in UICC stage I/II. MATERIAL AND METHODS: The investigators implemented a retrospective study. The study collective was composed of 124 @entity1 with @entity957 , who were treated in the department of oral and maxillofacial surgery during the years 2011-2015 at the University Medical Center Hamburg Eppendorf, Germany. We focused on age, gender, date of diagnosis, @entity5 stage (clinical and pathological), HPV status, occurrence of @entity3 , recurrences, date and frequency of staging and restaging (abdominal sonography, chest X-ray, CT Abdomen/Thorax, PET CT), follow up time and date of @entity204 . Descriptive and bivariate statistics were computed (chi-square test) and the P value was set at .05. RESULTS: 19 distant @entity3 were found in 13 out of 124 @entity1 (10.48%). Of those 20 @entity3 5 were found in the liver (26.32%), 11 in the lung (57.89%) and 4 in the bone (15.79%). Hepatic @entity3 co-occurred in every case with pulmonary @entity3 . In one case bone @entity3 occurred without the presence of pulmonary @entity3 . There was no significant correlation of @entity3 rate to T stage. But distant @entity3 were solely found in node positive @entity1 . This was significant for pulmonary @entity3 , not for liver @entity3 . Only one out of 11 pulmonary @entity3 was diagnosed by chest X-ray. CONCLUSION: Abdominal sonography and chest X-ray can be omitted as a standard procedure in staging of localized node negative @entity957 . A thoracic CT including the liver should be performed in @entity1 with suspected lymph nodes @entity3 in the neck on CT. A skeletal scintigraphy or alternatively a PET/PET-CT should be added if there are signs and symptoms suspicious for bone @entity3 .
