Spotlight on the utility of the Oncotype DX breast cancer assay.

The Oncotype DX assay was developed to address the need for optimizing the selection of adjuvant systemic therapy for patients with estrogen receptor (ER)-positive, lymph node-negative breast cancer. It has ushered in the era of genomic-based personalized cancer care for ER-positive primary breast cancer and is now widely utilized in various parts of the world. Together with several other genomic assays, Oncotype DX has been incorporated into clinical practice guidelines on biomarker use to guide treatment decisions.

Denosumab: Prevention and management of hypocalcemia, osteonecrosis of the jaw and atypical fractures.

Denosumab, a bone-modifying agent, reduces the risk of skeletal-related events in patients with bone metastases from solid tumors and is generally well tolerated. However, hypocalcemia, osteonecrosis of the jaw (ONJ) and atypical fracture are potential and important toxicities of denosumab therapy that require attention. In pivotal phase III trials in patients with bone metastases from solid tumors, the incidence of hypocalcemia was 9.

Hypocalcaemia in patients with metastatic bone disease treated with denosumab.

Background: This analysis was performed to further characterise treatment-emergent hypocalcaemia in patients with bone metastases receiving denosumab.

Methods: Laboratory abnormalities and adverse events of hypocalcaemia in patients with metastatic bone disease were analysed using data from three identically designed phase 3 trials of subcutaneous denosumab 120 mg (n = 2841) versus intravenous zoledronic acid 4 mg (n = 2836).

Results: The overall incidence of laboratory events of hypocalcaemia grade ⩾ 2 was higher with denosumab (12.

The impact of a genomic assay (Oncotype DX) on adjuvant treatment recommendations in early breast cancer.

Objectives: To assess how the recurrence score of the Oncotype DX breast cancer assay influences adjuvant systemic treatment decisions in the multidisciplinary meeting (MDM) for patients with early breast cancer (EBC) in Australia.

Design, Setting And Participants: A before-and-after study at three academic medical centres in Melbourne with patients and physicians serving as their own controls. Paired systemic adjuvant treatment recommendations were made in multidisciplinary meetings (MDMs) before and after Oncotype DX testing.

Prevalence of excessive tearing in women with early breast cancer receiving adjuvant docetaxel-based chemotherapy.

Purpose: To define the incidence and impact of tearing in patients receiving adjuvant docetaxel-based chemotherapy and assess for lacrimal duct obstruction (LDO) as a causative factor.

Patients And Methods: Consecutive patients with early breast cancer recommended for docetaxel-based chemotherapy with no prior ocular symptoms were included. Before and after completion of chemotherapy, patients underwent lacrimal drainage evaluation by computed tomographic dacrocystography (CT-DCG) and ophthalmic assessment.

Ganitumab with either exemestane or fulvestrant for postmenopausal women with advanced, hormone-receptor-positive breast cancer: a randomised, controlled, double-blind, phase 2 trial.

Background: Insulin-like growth factors (IGF-1 and IGF-2) bind to the IGF-1 receptor (IGF-1R), increasing cell proliferation and survival. Ganitumab is a monoclonal IgG1 antibody that blocks IGF-1R. We tested the efficacy and safety of adding ganitumab to endocrine treatment for patients with hormone-receptor-positive breast cancer.

A randomized phase 2 study of paclitaxel and carboplatin with or without conatumumab for first-line treatment of advanced non-small-cell lung cancer.

Introduction: This study evaluated the efficacy, safety, and pharmacokinetics of conatumumab combined with paclitaxel-carboplatin (PC) as first-line treatment for advanced non-small-cell lung cancer (NSCLC).

Methods: Patients (aged >18 years) with previously untreated advanced or recurrent NSCLC were randomized 1:1:1 (stratified by Eastern Cooperative Oncology Group performance status and disease stage) to receive up to six 3-week cycles of PC combined with conatumumab (arm 1, 3 mg/kg; arm 2, 15 mg/kg) or placebo (arm 3) every 3 weeks. The primary endpoint was progression-free survival (PFS).

Profile of cabozantinib and its potential in the treatment of advanced medullary thyroid cancer.

Medullary thyroid cancer is an uncommon malignancy for which until recently little effective treatment existed. It is often characterized by mutation and overexpression of the receptor tyrosine kinases RET (rearranged during transfection), VEGFR2 (vascular endothelial growth factor receptor 2) and MET (mesenchymal-epithelial transition factor), which make attractive targets for drug development. Cabozantinib is an orally bioavailable tyrosine kinase inhibitor which blocks MET, VEGRF2 and RET, and has shown considerable activity in medullary thyroid cancer in a Phase III trial, including in heavily pretreated patients.

Does immediate breast reconstruction compromise the delivery of adjuvant chemotherapy?

Background: Immediate breast reconstruction (IBR) provides psychological benefit to many early breast cancer patients however concerns persist regarding its potential impact on chemotherapy delivery. We investigated the association between IBR, complications and adjuvant chemotherapy delivery.

Method: Retrospective analysis of patients in an academic breast service, who underwent mastectomy, with or without reconstruction, and received adjuvant chemotherapy.

Vandetanib for the treatment of non-small-cell lung cancer.

Introduction: The use of targeted therapies in the treatment of advanced non-small-cell lung cancer (NSCLC) is increasing, especially as conventional chemotherapy affords relatively small benefits at a cost of increased toxicity. Two of the more established therapeutic targets in NSCLC are the vascular endothelial growth factor receptor (VEGFR) and epidermal growth factor receptor (EGFR). Vandetanib is an orally available inhibitor of VEGFR and EGFR signalling and is an attractive therapeutic agent owing to the simultaneous inhibition of both pathways.

Use of non-anthracycline regimens in early stage breast cancer in Australia.

Various factors have recently prompted a re-evaluation of the role of non-anthracycline regimens in early stage breast cancer (ESBC). Since 1990 anthracyclines have been a key component of chemotherapy regimens. However, there is increased understanding of the long-term, irreversible toxicities associated with these therapies, including cardiac failure and secondary leukemia.

Vandetanib plus pemetrexed for the second-line treatment of advanced non-small-cell lung cancer: a randomized, double-blind phase III trial.

Purpose: Vandetanib is a once-daily oral inhibitor of vascular endothelial growth factor receptor and epidermal growth factor receptor signaling. This randomized, placebo-controlled phase III study assessed the efficacy of vandetanib plus pemetrexed as second-line therapy in advanced non-small-cell lung cancer.

Patients And Methods: Patients (N = 534) were randomly assigned to receive vandetanib 100 mg/d plus pemetrexed 500 mg/m(2) every 21 days (n = 256) or placebo plus pemetrexed (n = 278).
