Neoadjuvant Therapy with Concurrent Docetaxel, Epirubicin, and Cyclophosphamide (TEC) in High-Risk HER2-Negative Breast Cancers.

Introduction: Concurrent anthracycline and taxane is an effective and efficient way to deliver neoadjuvant chemotherapy for HER2-negative breast cancers. Data on efficacy and tolerance to 6 cycles of concurrent docetaxel, epirubicin, and cyclophosphamide (TEC) is limited.

Method: All patients with HER2-negative breast cancers who received neoadjuvant TEC from January 2013 to December 2019 were reviewed.

Palbociclib and beyond for the treatment of HR + HER2- metastatic breast cancer: an Asian-Pacific perspective and practical management guide on the use of CDK4/6 inhibitors.

Breast cancer is the most frequent cancer amongst women worldwide including in Asia where the incidence rate is rapidly increasing. Even with treatment, around 30% of patients with early breast cancer progress to metastatic disease, with hormone receptor positive (HR+) and human epidermal growth factor receptor 2 negative (HER2-) breast cancer the most common phenotype. First-line endocrine therapy targeting the estrogen receptor signaling pathway provides a median progression-free survival or time to progression of 6-15 months in HR + HER2- metastatic breast cancer.

Changing pattern of recurrences in patients with early HER2-positive breast cancer receiving neoadjuvant chemotherapy in the era of dual anti-HER2 therapy.

Background: Over the last 10 years, there has been a major treatment revolution for early human epidermal growth factor receptor 2 (HER2)-positive breast cancer. We aimed to explore the outcome of different neoadjuvant chemotherapy in a tertiary breast cancer centre with early HER2-positive breast cancer as well as factors associated with pathological complete response (pCR) and recurrence-free survival (RFS). The pattern of recurrence was also studied.

Molecular Profiling of Patients With Advanced Colorectal Cancer: Princess Margaret Cancer Centre Experience.

Background: Molecular aberrations in KRAS, NRAS, BRAF, and PIK3CA have been well-described in advanced colorectal cancer. The incidences of other mutations are less known. We report results of molecular profiling of advanced colorectal cancer in an academic cancer center.

Pembrolizumab (Keytruda).

The programmed cell death protein 1 (PD1) is one of the checkpoints that regulates the immune response. Ligation of PD1 with its ligands PDL1 and PDL2 results in transduction of negative signals to T-cells. PD1 expression is an important mechanism contributing to the exhausted effector T-cell phenotype.

A phase I trial of ANG1/2-Tie2 inhibitor trebaninib (AMG386) and temsirolimus in advanced solid tumors (PJC008/NCI♯9041).

Background: There is crosstalk between the ANG-Tie2 and the PI3K/Akt/mTOR pathways. Combined ANG1/2 and mTOR blockade may have additive anti-cancer activity. The combination of trebananib, an inhibitor of ANG1/2-Tie2 interaction, with temsirolimus was evaluated in patients with advanced solid tumors to determine tolerability, maximum tolerated dose (MTD), and preliminary antitumor activity.

Pharmacokinetic assessment of dacomitinib (pan-HER tyrosine kinase inhibitor) in patients with locally advanced head and neck squamous cell carcinoma (LA SCCHN) following administration through a gastrostomy feeding tube (GT).

Background: Dacomitinib is an irreversible oral pan-HER tyrosine kinase inhibitor with antitumor activity demonstrated in patients with recurrent/metastatic (RM) SCCHN. A Phase I trial of dacomitinib with standard therapy in LA SCCHN is ongoing (NCT01737008). As enteral feeding is needed for many SCCHN patients, this study investigated the PK properties of dacomitinib when administered via GT (NCT01484847).

Advanced pancreatic cancer: flourishing novel approaches in the era of biological therapy.

The progress in the development of systemic treatment for advanced pancreatic cancer (APC) has been slow. The mainstream treatment remains using chemotherapy including gemcitabine, FOLFIRINOX, and nab-paclitaxel. Erlotinib is the only approved biological therapy with marginal benefit.
