A novel therapeutic strategy utilizing EpCAM aptamer-conjugated gemcitabine for targeting bladder cancer and cancer stem cells.

Gemcitabine (GEM) is a first line chemotherapy drug for bladder cancer (BCa). GEM's lack of specificity has led to disadvantages, resulting in low efficiency, especially when combined with the targeted treatment of BCa stem cells (CSCs), which is considered the cause of BCa recurrence and progression. To enhance the anti-cancer effect and reduce the side effects of GEM targeting of BCa cells/CSCs, an aptamer drug conjugate (ApDC) targeted delivery system was used to improve the efficiency of GEM in BCa therapy using EpCAM aptamer-GEM conjugates based on the epithelial cell adhesion molecule (EpCAM), which is highly expressed on the cell membrane of BCa cells/CSCs.

The Prognostic Significance of the CALLY Index in Ampullary Carcinoma: An Inflammation-Nutrition Retrospective Analysis.

Background: As a novel inflammatory-nutritional biomarker, the C-reactive protein-albumin-lymphocyte (CALLY) index has demonstrated significant prognostic value in various malignancies. However, research on its association with the prognosis of ampullary carcinoma (AC) is rare. This study aims to investigate the relationship between the CALLY index and the prognosis of patients with AC.

Case report: Watch-and-wait strategy in resectable esophageal cancer following neoadjuvant chemoimmunotherapy: a case series.

Neoadjuvant chemoimmunotherapy (NCIT) has improved pathological complete response and conferred survival benefits in patients with locally advanced esophageal cancer. However, surgical complications unrelated to the tumor continue to detract from patient outcomes. While the "watch-and-wait" strategy has been implemented in clinical complete responders following neoadjuvant therapy for rectal cancer, there is a lack of evidence supporting its practicability in esophageal cancer after NCIT.

Comparing PD-L1 and PD-1 inhibitors plus bevacizumab combined with hepatic arterial interventional therapies in unresetable hepatocellular carcinoma: A single-center, real-world study.

With the rise of anti-vascular endothelial growth factor antibody and programmed cell death-ligand 1 (PD-L1) regimens, particularly bevacizumab and atezolizumab, as first-line treatments for advanced hepatocellular carcinoma (HCC), there is a need to explore PD-L1 and programmed cell death 1 inhibitors in combination therapies for unresectable HCC (uHCC). Integrating systemic therapies with locoregional approaches is also emerging as a potent strategy. This study compares the outcomes of atezolizumab (PD-L1 inhibitor) and sintilimab (programmed cell death 1 inhibitor) with bevacizumab or its biosimilar, combined with hepatic arterial interventional therapies (HAIT) in uHCC patients.

Targeting ROR2 homooligomerization disrupts ROR2-dependent signaling and suppresses stem-like cell properties of human breast adenocarcinoma.

Breast cancer stem-like cells (CSCs) are enriched following treatment with chemotherapy, and posited as having a high level of plasticity and enhanced tumor-initiation capacity, which can enable cancer relapse. Here, we show that such features are shared by breast cancer (BCA) cells that express receptor tyrosine kinase-like orphan receptor (ROR2), which is expressed primarily during embryogenesis and by various cancers. We find that Wnt5a can induce ROR2 homooligomerization to activate noncanonical Wnt signaling and enhance tumor-initiation capacity of BCA cells.
