Prognostic factors of early recurrence after complete cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

Background: Although cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) offer the potential for long-term survival in peritoneal carcinomatosis, outcomes following CRS/HIPEC vary significantly.

Aim: To identify the clinical factors associated with progression-free survival (PFS) after complete CRS/HIPEC in patients with colorectal/high-grade appendiceal, ovarian, and gastric cancers.

Methods: We retrospectively evaluated the risk of recurrence within 1 year after CRS/HIPEC and its impact on overall survival (OS) in patients recruited between 2015 and 2020.

The Immunosuppressive Receptor CD32b Regulation of Macrophage Polarization and Its Implications in Tumor Progression.

Macrophages, pivotal components of the immune system, orchestrate host defense mechanisms in humans and mammals. Their polarization into classically activated macrophages (CAMs or M1) and alternatively activated macrophages (AAMs or M2) dictates distinct functional roles in immunity and tissue homeostasis. While the negative regulatory role of CD32b within the FC gamma receptor (FCγR) family is recognized across various immune cell types, its influence on macrophage polarization remains elusive.

Lipid Droplets in Lung Cancers Are Crucial for the Cell Growth and Starvation Survival.

For rapid and unlimited cell growth and proliferation, cancer cells require large quantities of nutrients. Many metabolic pathways and nutrient uptake systems are frequently reprogrammed and upregulated to meet the demand from cancer cells, including the demand for lipids. The lipids for most adult normal cells are mainly acquired from the circulatory system.

The potential and limitation of targeted chromosomal breakpoint sequencing for the fusion gene identification in lung cancer.

fusion genes are rare but important driver genes in lung cancer. Owing to their rarity, many clinicopathological features and treatment responses for each fusion variant are still largely unknown and require further investigation. RNA is the preferable template for the fusion gene screening, but deterioration of RNA in FFPE often makes the detection challenging.

In this study, we focused on the association of ANXA1 and chemosensitivity with a third generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI), Osimertinib, in lung cancer cells with EGFR mutations. The overexpression of ANXA1 was observed in the lung cancer cells studied.

A highly sensitive and specific real-time quantitative PCR for BRAF V600E/K mutation screening.

Mutations that lead to constitutive activation of key regulators in cellular processes are one of the most important drivers behind vigorous growth of cancer cells, and are thus prime targets in cancer treatment. BRAF V600E mutation transduces strong growth and survival signals for cancer cells, and is widely present in various types of cancers including lung cancer. A combination of BRAF inhibitor (dabrafenib) and MEK inhibitor (trametinib) has recently been approved and significantly improved the survival of patients with advanced NSCLC harboring BRAF V600E/K mutation.

The potential chemical structure of anti-SARS-CoV-2 RNA-dependent RNA polymerase.

An outbreak of coronavirus disease 2019 (COVID-19) occurred in Wuhan and it has rapidly spread to almost all parts of the world. For coronaviruses, RNA-dependent RNA polymerase (RdRp) is an important polymerase that catalyzes the replication of RNA from RNA template and is an attractive therapeutic target. In this study, we screened these chemical structures from traditional Chinese medicinal compounds proven to show antiviral activity in severe acute respiratory syndrome coronavirus (SARS-CoV) and the similar chemical structures through a molecular docking study to target RdRp of SARS-CoV-2, SARS-CoV, and Middle East respiratory syndrome coronavirus (MERS-CoV).

MET exon 14 skipping mutations and gene amplification in a Taiwanese lung cancer population.

Somatic mutations of MET gene are emerging as important driver mutations for lung cancers.
