Solely size-based response criteria may be unreliable in patients with gastrointestinal stromal tumors (GIST) treated with tyrosine kinase inhibitors, because they typically underestimate responses to treatment. As GISTs are generally hypervascularized and novel targeted drugs knowingly affect angiogenic signaling pathways, perfusion measurements are expected to deliver important information about their ...

Currently used morphologic criteria have limitations in assessing tumor response to chemotherapy because of the relatively slow tumor shrinkage as measured by conventional morphologic imaging. Functional imaging techniques show promising results in early assessment of tumor response to treatment. To quantitatively detect changes in tumor perfusion during chemotherapy with contrast-enhanced ...

BACKGROUND: CT scans of patients with febrile illness occasionally show hepatobiliary changes, although infection does not originate in the hepatobiliary system. These findings may cause radiologists and clinicians to misrecognize hepatobiliary diseases and initiate an inappropriate treatment. Thus, it is important to recognize hepatobiliary CT findings in cases of extrahepatobiliary ...

Myeloid-derived suppressor cells (MDSC) from mice bearing bone metastases differentiate into functional osteoclasts in vitro and in vivo, through a signaling pathway that relies on nitric oxide. In addition, MDSC-targeting drugs have been shown to robustly inhibit osteolysis. Thus, MDSC stand out as novel osteoclast progenitors and hence as candidate ...
