Sorafenib in Combination With Capecitabine: An Oral Regimen for Patients With HER2-Negative Locally Advanced or Metastatic Breast Cancer

Purpose Sorafenib is a multikinase inhibitor with antiangiogenic/antiproliferative activity. A randomized, double-blind, placebo-controlled phase IIB trial assessed sorafenib with capecitabine for locally advanced or metastatic human epidermal growth factor receptor 2 (HER2) -negative breast cancer. Patients and Methods Patients were randomly assigned to first-or second-line capecitabine 1,000 mg/m(2) orally twice a day for days 1 to 14 of every 21-day cycle with sorafenib 400 mg orally twice a day or placebo. The primary end point was progression-free survival (PFS). Results In total, 229 patients were enrolled. The addition of sorafenib to capecitabine resulted in a significant improvement in PFS versus placebo (median, 6.4 v 4.1 months; hazard ratio [HR], 0.58; 95% CI, 0.41 to 0.81; P = .001) with sorafenib favored across subgroups, including first-line (HR, 0.50; 95% CI, 0.30 to 0.82) and second-line (HR, 0.65; 95% CI, 0.41 to 1.04) treatment. There was no significant improvement for overall survival (median, 22.2 v 20.9 months; HR, 0.86; 95% CI, 0.61 to 1.23; P = .42) and overall response (38% v 31%; P = .25). Toxicities (sorafenib v placebo) of any grade included rash (22% v 8%), diarrhea (58% v 30%), mucosal inflammation (33% v 21%), neutropenia (13% v 4%), hypertension (18% v 12%), and hand-foot skin reaction/hand-foot syndrome (HFSR/HFS; 90% v 66%); grade 3 to 4 toxicities were comparable between treatment arms except HFSR/HFS (44% v 14%). Reasons for discontinuation in the sorafenib and placebo arms included disease progression (63% v 82%, respectively), adverse events (20% v 9%, respectively), and death (0% v 1%, respectively). Conclusion Addition of sorafenib to capecitabine improved PFS in patients with HER2-negative advanced breast cancer. The dose of sorafenib used in this trial resulted in unacceptable toxicity for many patients. A phase III confirmatory trial has been initiated with a reduced sorafenib dose.

Urgent percutaneous transcatheter embolization of hemorrhagic hepatic lesions with N-butyl cyanoacrylate

PURPOSE To report on our clinical experience with and the success rate and safety of percutaneous transcatheter embolization with N-butyl cyanoacrylate (NBCA) as the lone primary embolic agent used for arterial embolization of hemorrhagic liver lesions. MATERIALS AND METHODS This retrospective study enrolled all patients who presented to the emergency room with hemorrhagic liver lesions during a two-year period and were treated by percutaneous transcatheter embolization with NBCA. RESULTS Eight consecutive patients were evaluated, and 13 lesions were embolized exclusively with NBCA: eight pseudoaneurysms and five active bleeds. All patients were treated successfully using percutaneous transcatheter embolization with NBCA without re-bleedings or major complications. CONCLUSION Percutaneous transcatheter embolization with NBCA is a safe and effective method for treating hemorrhagic lesions.
