Administration of gemcitabine-cisplatin, the current standard therapy for advanced biliary tract cancers, results in median progression-free survival and overall survival of 8.0 and 11.7 months, respectively. New treatments offering improved survival outcomes are therefore needed. OBJECTIVE To evaluate the association between progression-free survival and the addition of nanoparticle albumin-bound (nab)-paclitaxel to gemcitabine-cisplatin for the treatment of patients with advanced biliary tract cancer. DESIGN, SETTING, AND PARTICIPANTS This open-label, single-arm, phase 2 clinical trial conducted at the University of Texas MD Anderson Cancer Center and the Mayo Clinic in Phoenix, Arizona, enrolled 62 patients with advanced biliary tract cancers between April 14, 2015, and April 24, 2017. INTERVENTIONS Patients initially received gemcitabine, 1000 mg/m 2 , cisplatin, 25 mg/m 2 , and nab-paclitaxel, 125 mg/m 2 , on days 1 and 8 of 21-day cycles. Owing to hematologic adverse events among the first 32 patients enrolled, these starting doses were reduced to 800, 25, and 100 mg/m 2 , respectively, for the remaining 28 patients. MAIN OUTCOMES AND MEASURES The primary trial end point was investigator-assessed progression-free survival in the intention-to-treat population. RESULTS Of 60 patients who started treatment, the mean (SD) age was 58.4 (11.0) years, 38 (63%) had intrahepatic cholangiocarcinoma, 9 (15%) had extrahepatic cholangiocarcinoma, 13 (22%) had gallbladder cancer, 47 (78%) had metastatic disease, and 13 (22%) had locally advanced disease. Median follow-up was 12.2 (95% CI, 9.4-19.4) months, and median progression-free survival was 11.8 (95% CI, 6.0 to 15.6) months. The partial response rate was 45%, and the disease control rate was 84%. Median overall survival was 19.2 months (95% CI, 13.2 months to not estimable). Patients in the safety population (n = 57) received a median of 6 (interquartile range, 3-11) cycles of treatment; 26 patients (46%) remained on their starting dose throughout the trial. Grade 3 or higher adverse events occurred in 58% of patients, and 9 patients (16%) withdrew owing to adverse events. Neutropenia was the most common grade 3 or higher adverse event, occurring in 19 patients (33%) overall. Post hoc analyses showed that treatment efficacy was not significantly associated with starting dose, tumor type, or disease status and that tolerability was improved with reduced-vs high-dose treatment. CONCLUSIONS AND RELEVANCE Treatment with nab-paclitaxel plus gemcitabine-cisplatin prolonged median progression-free survival and overall survival vs those reported for historical controls treated with gemcitabine-cisplatin alone. These findings will be tested in a phase 3 randomized clinical trial.

The combination of B + E in patients who had advanced HCC showed significant, clinically meaningful antitumor activity. B + E warrant additional evaluation in randomized controlled trials.

The present study suggests that Hes1 is essential for Hath1 gene suppression via Notch signaling. Moreover, the suppression of Hath1 is associated with goblet cell depletion in UC. Understanding the regulation of goblet cell depletion may lead to the development of new therapy for UC.

All too often researchers perform a Multivariate Analysis of Variance (MANOVA) on their data and then fail to fully recognize the true multivariate nature of their effects. The most common error is to follow the MANOVA with univariate analyses of the dependent variables. One reason for the occurrence of such errors is the lack of clear pedagogical materials for identifying and testing the multivariate effects from the analysis. The current paper consequently reviews the fundamental differences between MANOVA and univariate Analysis of Variance and then presents a coherent set of methods for plumbing the multivariate nature of a given data set. A completely worked example using genuine data is given along with estimates of effect sizes and confidence intervals, and an example results section following the technical writing style of the American Psychological Association is presented. A number of issues regarding the current methods are also discussed.

Objective: A phase II study was performed to evaluate the efficacy and tolerability of bevacizumab and erlotinib in advanced hepatocellular carcinoma (HCC) patients, and to investigate clinical and molecular predictors of outcome. Methods: 59 patients with advanced HCC received 10 mg/kg i.v. of bevacizumab every 14 days and 150 mg p.o. of erlotinib daily. The primary endpoint was progression-free survival (PFS) at 16 weeks. Clinical characteristics and plasma biomarkers expression levels were analyzed. Results: PFS at 16 weeks was 64% (95% CI 51–76): 14 patients achieved partial response (24%), 33 had stable disease (56%), 6 progressed (10%), and 6 were not evaluable (10%). Median overall survival was 13.7 months (95% CI 9.6–19.7), and median PFS was 7.2 months (95% CI 5.6–8.3). Grade 3–4 adverse events included fatigue (30%), diarrhea (17%), hypertension (14%), elevated transaminases (12%), and gastrointestinal hemorrhage (10%). High plasma angiopoietin-2, epidermal growth factor receptor, and endothelin-1, and lack of acneiform rash were associated with poor outcome. Conclusions: The combination of bevacizumab with erlotinib achieved encouraging results in patients with advanced HCC. Current correlatives may help to guide future HCC studies.
