Aim: This study aims to compare the efficiencies and toxicities of pegylated liposomal doxorubicin (PLD) based and epirubicin based chemotherapeutic regimens as neoadjuvant chemotherapy (NAC) for early breast cancer.

Patients And Methods: We retrospectively analyzed 391 patients with stage II-III breast cancer who received NAC in multiple centers. The efficiencies and toxicities of PLD and epirubicin based NAC regimens were compared by using both propensity-score matched (PSM) and unmatched data.

Article Synopsis
  • Breast cancer (BRCA) is the most common cancer among women, and improving treatment effectiveness is a significant challenge.
  • This study explores how loss of the tumour suppressor PTEN in myeloid cells affects anti-tumour immunity, revealing that it leads to increased stress granule assembly, which in turn impairs the immune response.
  • The findings suggest that PTEN deficiency in macrophages could contribute to drug resistance in BRCA treatment, indicating potential new strategies for improving therapy outcomes.

The effect mechanism of Na on reduction of NO with nitrogen-containing char, char(N) still lacks an in-depth study. Based on density functional theory, this study systematically discussed the heterogeneous reaction of NO with four char(N) models, that is, zigzag(N), zigzag(N)@Na, armchair(N), and armchair(N)@Na. Results show that the presence of Na promoted the chemisorption of NO on both zigzag(N) and armchair(N), especially zigzag(N).

Article Synopsis
  • Breast cancer is a big health issue for women, and a gene called MEG3 is important in understanding it better.
  • Researchers found that a chemical change (called hypermethylation) reduces MEG3's activity, which can lead to more cancer cell growth.
  • By using a special treatment to block this change, they found that MEG3 could be boosted again, slowing down cancer growth in cells and even in mice.

Background: Neoadjuvant chemotherapy (NAC) has been expanded to hormone receptor (HR) positive breast cancer (BC) patients with operable disease, to increase the likelihood of breast-conserving surgery. Genomic profiling at baseline would reveal NAC response relevant genomic features and signaling pathways, guiding clinical NAC utilization based on patients' genomic characteristics.

Methods: We prospectively studied stage II/III BC patients who were eligible for breast-conserving surgery.

MicroRNAs (miRNAs/miRs) play key roles in cancer progression. Extensive research has revealed that miR-26a is abnormally expressed and functions as a tumor suppressor in numerous types of cancer. Thus, the present study was undertaken to investigate the regulatory role and potential mechanism of action of miR-26a in breast cancer.

Background: Neoadjuvant chemotherapy (NAC) has become the best comprehensive treatment choice for breast cancer. Epirubicin is a crucial drug widely used in breast cancer chemotherapy, but it is often used with a reduced dosage in NAC for Chinese patients for its notable cardiotoxicity and frequent adverse events. This study aimed to investigate the efficacy and safety of standard-dose epirubicin in NAC for Chinese breast cancer patients retrospectively.

PTEN is a dual-specificity phosphatase that is frequently mutated in human cancer, and its deficiency in cancer has been associated with therapy resistance and poor survival. Although the intrinsic tumour-suppressor function of PTEN has been well established, evidence of its role in the tumour immune microenvironment is lacking. Here, we show that chemotherapy-induced antitumour immune responses and tumour suppression rely on myeloid-cell PTEN, which is essential for chemotherapy-induced activation of the NLRP3 inflammasome and antitumour immunity.
