@entity1 @entity5 @entity1358 @entity158 @entity3
PURPOSE: Bone scan is performed as part of the evaluation of bone @entity3 . We assessed the diagnostic value of bone scan in @entity1 with @entity1358 . MATERIALS AND METHODS: Bone scan was performed at presentation in 205 @entity1 with confirmed @entity1358 . Abnormal hot areas were further evaluated by x-ray, computerized tomography or surgery. RESULTS: Of the 56 @entity1 (27%) with an abnormal bone scan 32 (57%) had osseous metastatic lesions. Overall bone @entity3 was present in 34 of the 205 @entity1 (17%). Bone scan had 94% sensitivity and 86% specificity. Of the 124 @entity1 with clinically localized, stages T1-2N0M0 disease exclusive of bone @entity3 6 (5%) had bone @entity3 only, whereas 28 of 81 (35%) with locally advanced or @entity3 had bone @entity3 , including 12 (35%) who complained of @entity158 and 19 (56%) who presented with other symptoms due to local @entity5 growth or @entity3 at other sites. Three @entity1 (9%) were asymptomatic. There was osseous @entity3 without other @entity3 , enlarged regional lymph nodes or @entity158 in 7 @entity1 , including 1 with stage T1b (2% of all with that stage), 2 with stage T2 (5%), 1 with stage T3a (4%), 1 with stage T3b (6%), 1 with stage T3c (14%) and 1 with stage T4 (6%) disease. CONCLUSIONS: Bone scan may be omitted in @entity1 with stages T1-3aN0M0 @entity5 and no @entity158 because of the low proportion of missed cases with bone @entity3 .
