A randomized phase II study of paclitaxel and bevacizumab with and without gemcitabine as first-line treatment for metastatic breast cancer.

Background: The addition of bevacizumab to paclitaxel improved progression-free survival (PFS) of patients with metastatic breast cancer (MBC). We examined the efficacy and safety of adding gemcitabine to paclitaxel/bevacizumab (PB).

Patients And Methods: In this multicenter, open-label, randomized phase II trial, women with locally advanced or MBC were randomly assigned to receive paclitaxel 90 mg/m(2) (days 1, 8, 15) and bevacizumab 10 mg/kg (days 1, 15) with or without gemcitabine 1500 mg/m(2) (days 1, 15) in 28-day cycles.

Does Type of Tumor Histology Impact Survival among Patients with Stage IIIB/IV Non-Small Cell Lung Cancer Treated with First-Line Doublet Chemotherapy?

Chemotherapy regimens may have differential efficacy by histology in nonsmall cell lung cancer (NSCLC). We examined the impact of histology on survival of patients (N = 2,644) with stage IIIB/IV NSCLC who received first-line cisplatin/carboplatin plus gemcitabine (C/C+G) and cisplatin/carboplatin plus a taxane (C/C+T) identified retrospectively in the SEER cancer registry (1997-2002). Patients with squamous and nonsquamous cell carcinoma survived 8.

Neutropenia-related costs in patients treated with first-line chemotherapy for advanced non-small cell lung cancer.

Background: Neutropenia is a major adverse event often associated with chemotherapy administration. Neutropenia-related complications often lead to increased use of costly health care including inpatient and outpatient services. Monitoring and treatment of neutropenia thus place an economic burden on the health care system.

The cost of comorbid depression and pain for individuals diagnosed with generalized anxiety disorder.

Patients with generalized anxiety disorder (GAD) often have comorbid medical and psychiatric disorders and may incur higher costs. In this study, a total of 36,435 GAD patients aged 18 to 64 were identified from a claims database. Patient's total health care and component costs were compared between GAD patients with and without comorbid depression and pain using general linear models.

Costs of first-line doublet chemotherapy and lifetime medical care in advanced non-small-cell lung cancer in the United States.

Objectives: The purpose of this study was to identify total lifetime medical-care costs and costs associated with first-line chemotherapy treatment among older patients with stage IIIB/IV non-small-cell lung cancer treated with commonly used two-drug chemotherapy ("doublet") regimens in the United States.

Methods: Study patients included individuals aged 65 years and older who received a diagnosis of stage IIIB/IV non-small-cell lung cancer in a Surveillance, Epidemiology and End Results cancer registry between 1997 and 2002 and who received first-line treatment with commonly used doublet regimens. Patients were followed retrospectively in the Surveillance, Epidemiology and End Results-Medicare database to evaluate lifetime medical-care costs and costs while on first-line chemotherapy treatment.

Trends and predictors of first-line chemotherapy use among elderly patients with advanced non-small cell lung cancer in the United States.

Purpose: This study assessed first-line chemotherapy treatment patterns over time and identified predictors of chemotherapy use and treatment selection among elderly patients with newly diagnosed Stage IIIB/IV non-small cell lung cancer (NSCLC) in the United States.

Methods: Patients aged 65 years and older newly diagnosed with Stage IIIB/IV NSCLC between 1997 and 2002 were identified and followed through 2003 using the Surveillance, Epidemiology and End Results (SEER)-Medicare database to evaluate temporal trends in chemotherapy treatment. Multivariate logistic regression models were estimated to identify predictors of chemotherapy treatment and factors associated with use of cisplatin/carboplatin (platinum) and either a taxane or gemcitabine versus other treatments.

Use of effect size to determine optimal dose of duloxetine in major depressive disorder.

Objective: At effective doses, patients with major depressive disorder (MDD) treated with duloxetine have been found to experience significant symptom improvement as measured by HAMD(17) total score. In addition, duloxetine-treated patients have significantly higher remission and response rates compared with placebo. The objective of this analysis is to determine the optimal dose of duloxetine in MDD.

The cost of treating anxiety: the medical and demographic correlates that impact total medical costs.

The purpose of this retrospective, multivariate analysis is to examine how medical conditions and demographic characteristics affect the costs of treating individuals diagnosed with anxiety. Data from MarketScan Databases [The MEDSTAT Group, 2000] were used to identify individuals with new episodes of anxiety. Multivariate analysis was used, with the dependent variable being the log of total medical costs.

The benefits of switching smoking cessation drugs to over-the-counter status.

This paper provides an analysis of the benefits to society from the conversion of nicotine replacement drugs (nicotine patches and gum) in 1996 from sale by prescription only in the United States to over-the-counter (OTC) sales. To estimate these benefits, we first estimate statistical demand functions for nicotine patches and gum. Second, we calculate the effects of OTC conversion on sales of each type of nicotine replacement drug.
