Multicenter Prospective Study in HER2-Positive Early Breast Cancer for Detecting Minimal Residual Disease by Circulating Tumor DNA Analysis With Neoadjuvant Chemotherapy: HARMONY Study.

Background: Biomarkers to predict the recurrence risk are required to optimize perioperative treatment. Adjuvant chemotherapy for patients with human epidermal growth factor 2-positive (HER2-positive) early breast cancer is decided by pathological responses of neoadjuvant chemotherapy (NAC). However, whether pathological responses are appropriate biomarkers is unclear.

NKX2‑1 copy number alterations are associated with oncogenic, immunological and prognostic remodeling in non‑small cell lung cancer.

NK2 homeobox 1 (NKX2-1) copy number alterations (CNAs) are frequently observed in lung cancer. However, little is known about the complete landscape of focal alterations in NKX2-1 copy number (CN), their clinical significance and their therapeutic implications in non-small cell lung cancer (NSCLC). The correlations between NKX2-1 expression and EGFR driver mutations and programmed death ligand 1 (PD-L1) co-expression were studied using immunohistochemistry and PCR from the tumors of recruited Filipino patients (n=45).

The differential prognostic implications of PD-L1 expression in the outcomes of Filipinos with -mutant NSCLC treated with tyrosine kinase inhibitors.

Background: The tumor immune microenvironment influences tumor evolution in non-small cell lung cancer (NSCLC). Yet, the prognostic value of programmed death-ligand 1 (PD-L1) in epidermal growth factor receptor (EGFR)-mutant NSCLC remains controversial. Additionally, prognostic studies in Filipinos with EGFR-mutant NSCLC remain unexplored to this day.

A new era of the Asian clinical research network: a report from the ATLAS international symposium.

This report summarizes the presentations and discussions in the first Asian Clinical Trials Network for Cancers (ATLAS) international symposium that was held on 24 April 2022, in Bangkok, Thailand, and hosted by the National Cancer Center Hospital (NCCH), co-hosted by the Pharmaceuticals and Medical Devices Agency (PMDA), Clinical Research Malaysia (CRM) and the Thai Society of Clinical Oncology (TSCO), and supported by Embassy of Japan in Thailand. Since 2020, the NCCH has conducted the ATLAS project to enhance research environments and infrastructures to facilitate international clinical research and cancer genomic medicine in the Asian region. The purpose of the symposium was to discuss what we can achieve under the ATLAS project, to share the latest topics and common issues in cancer research and to facilitate mutual understanding.

Folic acid-based intervention in non-ST elevation acute coronary syndromes.

Homocysteinemia is a risk factor for cardiovascular diseases. Folic acid combined with vitamins B(6) and B(12) is effective in lowering homocysteine levels. This randomized placebo-controlled study was designed to determine the effect of a folic acid-based supplement on secondary prevention of clinical events in non-ST-segment elevation acute coronary syndromes.

Homocysteine predicts adverse clinical outcomes in unstable angina and non-ST elevation myocardial infarction: implications from the folate intervention in non-ST elevation myocardial infarction and unstable angina study.

Background: Unstable angina and non-ST elevation myocardial infarction (NSTEMI) are common acute coronary events. Homocysteine is a novel risk factor for coronary heart diseases. Together with the conventional risk factors, they may affect the outcome of non-ST coronary events.
