Background: Extramural venous invasion (EMVI) is a prognostic factor in rectal cancer. There are two types: EMVI detected by magnetic resonance imaging (MRI) (mr-EMVI) and EMVI detected by pathology (p-EMVI). They have been separately evaluated, but they have not yet been concurrently evaluated.

Materials And Methods: Thirty-nine women with locally recurrent breast cancer after standard therapy underwent selective intra-arterial chemotherapy followed by embolization using drug-eluting microspheres for locally recurrent tumors and axillary lymph node metastases. Tumor response and toxicity were assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) and Common Terminology Criteria for Adverse Events (CTCAE), and survival was evaluated by the Kaplan‒Meier method.
A case of extensive esophageal stenosis and bleeding caused by advanced gastric cancer in esophago-gastric junction treated by the transarterial chemoembolization(TACE)was reported. After standard systemic chemotherapy and radiotherapy, TACE was introduced to control these symptoms. A microcatheter was successfully advanced to the left gastric artery and esophageal artery arising from the thoracic aorta.

Material And Methods: The subjects were 60 patients with hepatic tumors: 20 patients with metastatic liver tumors with a normal liver and 40 with hypervascular hepatocellular carcinoma (HCC) with liver cirrhosis. The region of interest was set in the portal vein, and CTAP was automatically started after the triggering threshold (180 HU) was reached.
