Objective The aim of this study was to clarify the predictive significance of nodal calcification in terms of the therapeutic option of 131I therapy in papillary thyroid carcinoma (PTC) patients. Methods We reviewed 19 computed tomography (CT) examinations of PTC patients on receiving 131I therapy for the presence of nodal calcification, and compared the 131I whole-body scintigraphy and 18F-2-fluoro-2-deoxy-D-glucose...
Background The therapeutic advances in breast cancer have improved the survival of patients with early disease; however, survival improvement of patients with recurrent disease remains ambiguous. In this retrospective study, we examined whether disparities in survival improvement exist in patients with recurrent breast cancer with distant metastasis. Methods The survival time of 126 patients who...
The optimum sentinel node biopsy (SNB) mapping method for breast cancer remains to be determined. No matter which mapping agents are used, 2-site injection may be superior to 1-site injection in limiting the false-negative rate. We examined whether a double-mapping method with subareolar injection of blue dye and peritumoral injection of green dye would decrease the false-negative rate of dye-only...
Background. The role of extrinsic autonomic nerves in regulation of colonic contractile activity is not well understood. Methods. Twelve dogs had 6 strain gauge force transducers implanted in the colon and were divided into 3 experimental groups: (1) a control group, (2) an extrinsic denervation group (denervation group), and (3) an extrinsic denervation with proximal intrinsic myenteric plexus transection...
Background. Several neural and hormonal factors are known to affect the motility of the sphincter of Oddi. However, the precise mechanisms of the control of sphincter motility have not been completely explored. We investigated the relationship of canine biliary sphincter motility when it is extrinsically denervated by neural isolation of the pancreatoduodenal region. Methods. Interdigestive and postprandial...
