    ABSTRACT: Combination therapy with ixabepilone and capecitabine (cape) is approved for use in patients with locally advanced/metastatic breast cancer that is resistant to treatment with anthracyclines or taxanes. The current study evaluated the trade-off between quality and quantity of life using quality-adjusted time without symptoms or toxicity (Q-TWiST) outcomes. Within the trial, 752 women were randomly assigned to receive either the combination of ixabepilone and cape (once every 21 days) or cape alone (on days 1-14). The area under the survival curve was partitioned into 3 health states: toxicity (TOX), time without symptoms of disease progression or toxicity, and recurrence (relapse [REL]). The mean time in each health state was weighted by a range of utilities and summed to estimate quality-adjusted survival (QAS). Patient-reported outcomes were also evaluated using the Functional Assessment of Cancer Therapy (FACT)-Breast Symptom Index (FBSI). A statistically significant difference between groups with regard to change from baseline FBSI scores favoring the cape group was observed (P = .0002), but no differences were observed after adjusting for deaths in the analysis. All combinations of utilities for REL and TOX resulted in an observed difference in QAS favoring combination therapy. Differences were found to be statistically significant for comparisons, with higher tolerance for TOX. QAS was found to be greater for the combination therapy group (42.2 weeks vs 38.4 weeks), assuming the base case scenario of utility equal to 0.5 for both TOX and REL (P = .0227). The Q-TWiST analysis supports a positive benefit-risk ratio for the combination of ixabepilone plus cape in patients with advanced/metastatic breast cancer that is refractory to anthracyclines and taxanes versus cape alone, despite the potential for added toxicities with combination therapy.

    ABSTRACT: The incidence of hepatocellular carcinoma (HCC) in the United States is increasing. Surveillance may affect the stage at diagnosis and consequently the treatment options available for HCC. We evaluated risk factors for HCC, the proportion of cases detected via surveillance, tumor characteristics, treatment approaches, and overall patient survival in a referral center cohort. The study included all patients diagnosed with HCC at the Mayo Clinic, Rochester, Minnesota, from 2007 to 2009 (n = 460). Clinical information was retrospectively abstracted from the medical record. Hepatitis C virus (HCV, 36%), alcohol use (29%), and nonalcoholic fatty liver disease (NAFLD, 13%) were the most common risk factors for HCC. HCV was present in 56% of patients younger than 60. NAFLD was present in 19% of patients older than 60. HCC was detected during surveillance in 31% of patients. Patients with worse liver function were more likely to be on surveillance. Transarterial chemoembolization, surgical resection, and liver transplantation were the most common treatment approaches for HCC. Patients diagnosed with HCC during surveillance had less advanced disease, were more likely to be eligible for potentially curative treatments, and had increased survival times (P < .001). At a major US referral center, the predominant HCC etiologies were HCV, alcohol use, and NAFLD. HCCs were detected during surveillance in the minority of patients. HCCs detected during surveillance were of less advanced stage, and patients were more likely to receive treatment that prolonged their survival.

    ABSTRACT: More than 50% of the worldwide cases of hepatocellular carcinoma occur in China, and this malignancy currently represents the country's second leading cause of cancer death in cities and the leading cause in rural areas. Despite recent advances in the control and management of hepatocellular carcinoma within China, this disease remains a major health care issue. The global HCC BRIDGE study, designed to assess patterns of hepatocellular carcinoma therapy use and associated outcomes across real-world clinical practice, has recently been expanded as a national study in China, allowing a detailed analysis of hepatocellular carcinoma in this important country. The global HCC BRIDGE study is a multiregional longitudinal cohort trial including patients newly diagnosed with hepatocellular carcinoma between January 1, 2005, and June 30, 2011, who are receiving treatment for hepatocellular carcinoma via sites in the Asia-Pacific, European, and North American regions. The HCC BRIDGE China national study comprises the portion of the global HCC BRIDGE study conducted within mainland China. Patients will be followed from time of diagnosis of hepatocellular carcinoma (post-January 1, 2005) to time of death or December 31, 2011, whichever comes first. Data will be collected on demographic/clinical characteristics, relevant laboratory values, hepatocellular carcinoma/underlying liver disease treatment, tumor response, adverse events, hospitalizations, and overall survival. The primary study end point is overall survival; secondary end points are disease progression, treatment-limiting adverse events, and treatment failure. At the time of writing, 15 sites have selected for participation across all 7 traditional regions of China (North, North-East, East, South, South-West, North-West, and Central). The anticipated study population from the China national study is approximately 9000 patients. Findings from the HCC BRIDGE China national study, the first geographically representative study of hepatocellular carcinoma in China, will contribute to the understanding of patterns of therapy use and related clinical outcomes and will provide further information on continuing unmet needs for hepatocellular carcinoma throughout this important country.
