Ixabepilone and Carboplatin for Hormone Receptor Positive/HER2-neu Negative and Triple Negative Metastatic Breast Cancer.

Background: Hormonal therapies and single-agent sequential chemotherapeutic regimens are the standards of care for HER2 metastatic breast cancer (MBC). However, treating patients with hormone-refractory and triple negative (TN) MBC remains challenging. We report the results of combined ixabepilone and carboplatin in a single-arm phase II trial.

TITAN: phase III study of doxorubicin/cyclophosphamide followed by ixabepilone or paclitaxel in early-stage triple-negative breast cancer.

Purpose: Ixabepilone is a microtubule stabilizer with activity in taxane-refractory metastatic breast cancer and low susceptibility to taxane-resistance mechanisms including multidrug-resistant phenotypes and high β-III tubulin expression. Since these resistance mechanisms are common in triple-negative breast cancer (TNBC), ixabepilone may have particular advantages in this patient population. This study evaluated the substitution of ixabepilone for paclitaxel following doxorubicin/cyclophosphamide (AC) in the adjuvant treatment of early-stage TNBC.

A randomized trial of avatrombopag, an investigational thrombopoietin-receptor agonist, in persistent and chronic immune thrombocytopenia.

Stimulation of platelet production by thrombopoietin-receptor agonists (TPO-RAs) is an effective second-line treatment in immune thrombocytopenia (ITP). This 28-day phase 2 study assigned subjects with ITP of ≥3 months to once-daily oral avatrombopag (2.5, 5, 10, or 20 mg), an investigational nonpeptide TPO-RA active in humans, or placebo; subjects completing randomized treatment could enroll in a 24-week extension study.

Final overall survival: fulvestrant 500 mg vs 250 mg in the randomized CONFIRM trial.

Background: At the time of the initial analysis of overall survival (OS) for the Comparison of Faslodex in Recurrent or Metastatic Breast Cancer (CONFIRM) randomized, double-blind, phase III trial, approximately 50% of patients had died. A final analysis of OS was subsequently planned for when 75% of patients had died.

Methods: Patients were randomly assigned 1:1 to fulvestrant 500 mg administered as two 5-mL intramuscular injections on days 0, 14, and 28 and every 28 (±3) days thereafter or fulvestrant 250 mg administered as two 5-mL intramuscular injections (one fulvestrant and one placebo [identical in appearance to study drug]) on days 0, 14 (two placebo injections only), and 28 and every 28 (±3) days thereafter.

Pegylated liposomal doxorubicin plus carboplatin in patients with metastatic breast cancer: a phase II study.

Background: We determined the objective response rates produced by pegylated liposomal doxorubicin (PLD) plus carboplatin with/without trastuzumab (Herceptin).

Patients And Methods: Patients with measurable disease were stratified by taxane treatment history and human epidermal growth factor receptor-2 status.

Treatment: PLD 30 mg/m(2) followed by carboplatin, day 1 of each 28-day cycle; human epidermal growth factor receptor-2 (HER2)-positive patients also received trastuzumab.

Pathways, outcomes, and costs in colon cancer: retrospective evaluations in two distinct databases.

Purpose: The goal of this study was to use two separate databases to evaluate the clinical outcomes and the economic impact of adherence to Level I Pathways, an evidence-based oncology treatment program in the treatment of colon cancer.

Patients And Methods: The first study used clinical records from an electronic health record (EHR) database to evaluate survival according to pathway status in patients with colon cancer. Disease-free survival in patients receiving adjuvant treatment and overall survival in patients receiving first-line therapy for metastatic disease was calculated.

Presence of the metabolic syndrome is associated with shorter time to castration-resistant prostate cancer.

Background: Metabolic syndrome (MS) is a set of risk factors that includes obesity and insulin resistance and has been implicated in the development of prostate cancer. Its impact on androgen deprivation therapy (ADT) efficacy has not been studied.

Patients And Methods: Retrospective study of prostate cancer patients seen from 1998 to 2005 in a medical oncology clinic.

Cost effectiveness of evidence-based treatment guidelines for the treatment of non-small-cell lung cancer in the community setting.

Purpose: The goal of this study was to evaluate the cost-effectiveness of Level I Pathways, a program designed to ensure the delivery of evidence-based care, among patients with non-small-cell lung cancer (NSCLC) treated in the outpatient community setting.

Patients And Methods: We included patients with NSCLC initiating a chemotherapy regimen between July 1, 2006, and December 31, 2007, at eight practices in the US Oncology network. Patients were characterized with respect to age, sex, stage, performance status, and line of therapy and were classified by whether they were treated according to Level I Pathways guidelines.

Outpatient genetic risk assessment in women with breast cancer: one center's experience.

A chart audit at one cancer center, of 193 women with breast cancer, was completed to assess whether a complete family history that may indicate genetic predisposition was obtained and if that information led a provider to suggest risk reduction strategies. A risk management tool, which included a pedigree template, was used. Of the 193 charts reviewed, 88.

Aprepitant: an oral NK1 antagonist for the prevention of nausea and vomiting induced by highly emetogenic chemotherapy.

This paper reviews the clinical profile of aprepitant, the first neurokinin-1 (NK(1)) receptor antagonist to be approved for use in the prevention of chemotherapy-induced nausea and vomiting. When given to patients receiving highly emetogenic chemotherapy, aprepitant in combination with a 5-hydroxytryptamine type-3 (5HT(3)) receptor antagonist and a corticosteroid provides significantly improved protection from chemotherapy-induced nausea and vomiting over that which has been previously achievable with current antiemetics.

Results of a Phase II study of carboplatin plus gemcitabine in patients with untreated extensive small cell lung cancer.

Purpose: To determine the response rate (RR) and survival produced by carboplatin + gemcitabine therapy in patients with untreated extensive small cell lung cancer (ESCLC).

Patients And Methods: Treatment consisted of carboplatin (AUC = 5) on day 1 and gemcitabine (1100 mg/m(2)) on days 1 and 8 of each 21-day cycle for 4 planned cycles (additional cycles allowed as per treating physician). ECOG performance status 0/1/2 was 29, 58, and 13%.

Results of a phase II study of weekly paclitaxel plus carboplatin in patients with extensive small-cell lung cancer with Eastern Cooperative Oncology Group Performance Status of 2, or age > or = 70 years.

Purpose: To determine the 1-year survival, response rate (RR), time to progression (TTP), and safety of weekly paclitaxel plus carboplatin (PC) in patients with extensive small-cell lung cancer (ESCLC) with an Eastern Cooperative Performance Status performance status (PS) of 2 or an age > or = 70 years.

Patients And Methods: Patients were treated with PC (paclitaxel 80 mg/m(2) and carboplatin area under the curve = 2) by intravenous infusion on days 1, 8, and 15 of every 4-week cycle for up to six cycles.

Results: Between July 2000 and December 2001, 77 eligible patients (50.
