Pulmonary multifunctional nano-oncological modules for lung cancer treatment and prevention

Area of Science:

• Oncology and Nanotechnology
• Pulmonary Drug Delivery

Background:

• Lung cancer mortality remains high, despite the lung being an accessible organ.
• Conventional lung cancer treatments face challenges from the complex lung environment.
• Extracellular and intracellular barriers impede therapeutic efficacy in lung cancer.

Purpose of the Study:

• To review the challenges in lung cancer treatment.
• To explore advanced nano-oncological modules for pulmonary drug delivery.
• To highlight strategies overcoming lung-specific therapeutic impediments.

Main Methods:

• Review of current literature on lung cancer treatment challenges.
• Analysis of multifunctional nano-oncological modules for pulmonary delivery.
• Examination of strategies to overcome extracellular and intracellular barriers.

Main Results:

• The lung's complex extracellular environment (mucus, fluid, cilia) hinders drug delivery.
• Intracellular barriers (enzymatic degradation, translocation, endosomal escape) limit treatment effectiveness.
• Multifunctional nano-oncological modules offer promising solutions for pulmonary drug delivery.

Conclusions:

• Overcoming lung-specific barriers is crucial for effective lung cancer therapy.
• Nanotechnology-based pulmonary delivery systems show potential to enhance treatment outcomes.
• Advanced nano-modules can address both extracellular and intracellular challenges in lung cancer.
