Functionalized Nanomaterials In Pancreatic Cancer Theranostics And Molecular Imaging

Area of Science:

• Oncology
• Nanotechnology
• Immunology

Background:

• Pancreatic cancer (PC) and pancreatic ductal adenocarcinoma (PDAC) are highly lethal malignancies with limited effective treatments.
• Conventional therapies often cause significant side effects due to non-specific action.
• Advancements in understanding PDAC carcinogenesis provide a basis for developing novel therapeutic strategies.

Purpose of the Study:

• To review the application of targeted nanoparticles as an alternative to conventional pancreatic cancer treatment.
• To discuss the principles of nanoparticle-based cancer therapy, including enhanced permeability and retention (EPR) effects.
• To explore the potential of functionalized nanoparticles for early detection, targeted drug delivery, hyperthermia, immunotherapy, and gene therapy in pancreatic cancer.

Main Methods:

• Review of current research on nanoparticle-based therapies for pancreatic cancer.
• Discussion of molecular markers for targeted nanoparticle functionalization.
• Exploration of immunological factors influencing nanoparticle uptake.
• Examination of theranostic nanocarriers for combined diagnosis and therapy.

Main Results:

• Targeted nanoparticles can efficiently target tumor cells, reducing chemotherapy side effects.
• Functionalized nanoparticles can detect pancreatic cancer cells using specific signaling molecules.
• Nanoparticles can induce tumor cell death via hyperthermia, drug delivery, immunotherapy, or gene therapy.
• Nanoparticles serve as effective co-delivery vehicles for adjuvants and tumor-associated antigens, activating the immune system.

Conclusions:

• Targeted nanoparticles represent a significant advancement in pancreatic cancer treatment, offering improved efficacy and reduced toxicity.
• Functionalization of nanoparticles with specific markers enhances targeting and detection capabilities.
• Theranostic nanocarriers hold promise for revolutionizing pancreatic cancer treatment through integrated diagnostic and therapeutic functions.
