Abstract

The present study investigated the potential utility of contrast‑enhanced abdominal ultrasonography (CEUS), using SonazoidTM, in colorectal cancer (CRC). Three patients were subjected to CEUS with SonazoidTM. Surgical specimens were immunostained for CD31. Numbers of blood vessels positive for CD31 were analyzed in each of five fields at x400 magnification and averaged to determine blood vessel density. Blood vessel density was compared between non‑tumorous and tumorous areas. Prior to the administration of SonazoidTM, CRC was illustrated as irregular‑shaped wall thickening. One minute after the administration of SonazoidTM, the majority of the thickened wall was enhanced, while some parts of the thickened wall remained unenhanced. Blood vessel densities of non‑tumorous and tumorous areas in patient two were 25.2±2.5 and 5.2±1.1 (P<0.0001). Blood vessel densities of non‑tumorous and tumorous areas in patient three were 19.0±3.1 and 2.2±0.8 (P<0.0001). Tumorous areas of CRC were not enhanced 1 min after the administration of SonazoidTM. Blood vessel density was lower in tumorous areas compared with non‑tumorous areas, as evidenced by immunohistochemistry for CD31. These findings suggest that CEUS may be useful for the determination of the extent of CRC.
