Background: The combination of neoadjuvant chemotherapy and anti-angiogenesis therapy for patients with triple-negative breast cancer (TNBC) remains inadequately supported by evidence. We conducted a single-arm, open-label, multicenter, phase II trial to evaluate the efficacy and toxicity of anlotinib plus epirubicin and cyclophosphamide followed by paclitaxel in patients with IIB to IIIA stage TNBC.
Methods: Newly diagnosed patients received epirubicin at 90 mg/m and cyclophosphamide at 600 mg/m followed by docetaxel at 100 mg/m (21 days per cycle; total of 4 cycles), along with oral anlotinib (12 mg qd, d1-14; 21 days per cycle; total of 4 cycles).
Lung adenocarcinoma, the most common histological subtype of non-small cell lung cancer, exhibits heterogeneity that enables adaptability, limits therapeutic success, and remains incompletely understood. Our team uncovers that lncRNA related to chemotherapy resistance in lung adenocarcinoma (lncCRLA) is preferentially expressed in lung adenocarcinoma cells with the mesenchymal phenotype. lncCRLA can not enhance chemotherapy resistance in lung adenocarcinoma due to its binding to RIPK1 in exosomes, which is released into intercellular media and transferred by exosomes from mesenchymal-like to epithelial-like cells.

Methods: Four SNPs (rs785468, rs785467, rs3795666, and rs17024525 in PIK3R3 and NOTCH2) from 709 liver cancer patients and 700 healthy controls were genotyped using the Agena MassARRAY system.
Pancreatic cancer (PC) is one of the most lethal diseases, with a 5‑year survival rate of <9%. Perineural invasion (PNI) is a common pathological hallmark of PC and is correlated with a poor prognosis in this disease. Hyperglycemia has been shown to promote the invasion and migration of PC cells; however, the effect of hyperglycemia on the PNI of PC and its underlying mechanism remains unclear.

How c-Src affects EGFR-related signaling and targeted therapy remains elusive. Initially, caspase-8 phosphorylated at tyrosine 380 by c-Src predominantly enhancing c-Src activation to facilitate metastasis through attaining epithelial-mesenchymal transition (EMT) phenotype in lung adenocarcinoma.

However, the precise mechanisms of EMT-related chemotherapy resistance remain unclear. c-Src-mediated caspase 8 phosphorylation essential for EMT in lung adenocarcinoma cell lines preferentially occurs in cells with the mesenchymal phenotype, resulting in chemoresistance to cisplatin plus paclitaxel in patients with resectable lung adenocarcinoma and a significantly worse 5-year PFS.

Purpose: Targeting DNA repair mechanisms to induce apoptosis may be a promising strategy for breast cancer treatment. Olaparib is proved to have anticancer effect by inhibiting DNA repairing protein poly (ADP-ribose) polymerase (PARP). However, the cytotoxicity of olaparib is very limited to homologous recombination-proficient cells.

Thus, we assessed whether a perioperative regimen of paclitaxel, cisplatin, and 5- fluorouracil (PCF) improved outcomes among patients with curable squamous cell carcinoma of esophagus comparing with preoperative chemotherapy alone.
Methods: Overall, 346 patients with resectable squamous cell carcinoma of esophagus were randomly assigned to receive surgery plus perioperative chemotherapy (175, arm A) or preoperative chemotherapy (171, arm B).
