Aim:The goal of the study was to evaluate the efficacy and safety of balloon-occluded transarterial chemoembolization (B-TACE) of hepatocellular carcinoma (HCC) using miriplatin (a lipophilic anticancer drug) and gelatin particles.Methods: B-TACE was performed for 62 HCC nodules in 33 patients who could not be treated by surgical resection or radiofrequency ablation. All 33 patients had a history of transarterial chemoembolization (TACE) treatment prior to B-TACE. As a historical comparison, we investigated 40 nodules in 28 patients treated by TACE using a conventional microcatheter (C-TACE), miriplatin and gelatin particles. The therapeutic effect per tumor was compared between the groups based on the Response Evaluation Criteria in Cancer Study Group of Japan (RECICL) and side-effects were compared based on the Common Terminology Criteria for Adverse Events (ver. 4.0). Results:The therapeutic efficacy after 4-12 weeks was evaluated in 59 nodules in the B-TACE group and in 37 nodules in the C-TACE group. Of these nodules, TE4 occurred in 29 (49.2%) in the B-TACE group and in 10 (27%) in the C-TACE group. Local efficacy was significantly higher in nodules treated by B-TACE than by C-TACE. The side-effects on hepatic function were similar in the two groups. Conclusion:Our results suggest that B-TACE with miriplatin is a useful treatment for hepatocellular carcinoma.

CEUS allows us to differentiate active bleeding (presence of contrast medium in the ascites) from nonactive bleeding.

A 68-year-old man with a history of diabetes mellitus was admitted to our hospital with a diagnosis of acute pancreatitis. Abdominal computed tomography revealed a suspicious tumor in the body of the pancreas, along with a dilated main pancreatic duct and edema of the pancreatic tail. Endoscopic retrograde pancreatography was performed after treating the patient's pancreatitis. When a cannula tip was advanced beyond the stenosis, deep into the distal pancreatic duct, thick white pus was evacuated. A bacteriological examination of the aspirated pancreatic juice revealed Enterobacter cloacae, and a cytological examination revealed adenocarcinoma. The diagnosis was acute obstructive suppurative pancreatic ductitis associated with pancreatic carcinoma.

Objectives We aimed to investigate whether contrast‐enhanced ultrasound (CEUS) could be useful for early evaluation of the treatment response to transcatheter arterial chemoembolization (TACE) of hepatocellular carcinoma (HCC). Methods This study retrospectively selected HCCs in which homogeneous retention of iodized oil was confirmed on non–contrast‐enhanced computed tomography performed immediately after TACE. Therapeutic responses of HCCs were evaluated by CEUS 1 to 2 days after TACE and by contrast‐enhanced computed tomography (CECT) approximately 4 weeks after TACE. We investigated the noninferiority of CEUS 1 to 2 days after TACE to CECT approximately 4 weeks after TACE in terms of the diagnostic accuracy of the therapeutic response to TACE on HCC. Results Eighty‐nine HCCs were enrolled in this study between April 2014 and June 2016. A complete response was observed in 57 of 89 nodules (64.0%), and an incomplete response was observed in the remaining 32 nodules (36.0%). The accuracy rates for CEUS 1 to 2 days after TACE and CECT approximately 4 weeks after TACE in the therapeutic effect of TACE on HCCs were 83.1% (95% confidence interval, 73.7%–90.2%) and 83.1% (95% confidence interval, 73.7%–90.2%), respectively. The difference in diagnostic accuracy between methods was 0%, which was below the predetermined noninferiority limit of 15%, and CEUS 1 to 2 days after TACE was noninferior to CECT approximately 4 weeks after TACE. Conclusions Our results suggest that CEUS is a useful modality for early therapeutic evaluation of TACE for HCC, and we can thus plan the next treatment strategies for HCC within a few days after TACE.
