The further accumulation of clinical data is needed to determine the optimal therapeutic approach for these neoplasms.

We evaluated clinical outcomes of disseminated intravascular coagulation (DIC) in patients with hematological malignancies treated with synthetic protease inhibitors (SPIs) and compared the effects of gabexate mesilate (FOY) and nafamostat mesilate (FUT). We retrospectively examined 127 patients [acute myeloid leukemia (n = 48), acute lymphoblastic leukemia (n = 25), and non-Hodgkin lymphoma (n = 54)] with DIC, who were diagnosed according to Japanese Ministry of Health, Labour and Welfare criteria and treated with SPIs [FOY (n = 55) and FUT (n = 72)] at our hospital from 2006 to 2015. The DIC resolution rates on days 7 and 14 were 42.6% and 62.4%, respectively. No significant differences were observed in DIC resolution rates between the FUT and FOY groups [40.3% vs. 45.5% (day 7), P = 0.586; 56.3% vs. 69.8% (day 14), P = 0.179, respectively]. Multivariate analysis revealed that response to chemotherapy was the only independent predictor of DIC resolution on days 7 and 14 (ORR 2.81, 95% CI 1.32-5.98, P = 0.007; ORR 2.51, 95% CI 1.12-5.65, P = 0.026). Resolution of DIC was correlated with improvement of background hematological malignancies, and no significant differences were observed between the two SPIs.

• Gadoxetic acid-enhanced MR features of cholangiolocellular carcinoma (CoCC) resembled those of intrahepatic cholangiocarcinoma (ICC). • Gadoxetic acid-enhanced MR features of CoCC largely differed from those of hepatocellular carcinoma. • Dot-/band-like internal enhancement of CoCC may be helpful for differentiating from ICC. • Arterial ring enhancement of CoCC was larger than that of ICC.

Key Points The cost of TKI for treatment of CML can be substantially saved by treatment discontinuation in patients who achieved DMR. Starting treatment with imatinib is the most cost-effective strategy even after incorporation of treatment discontinuation.
