Photothermal Therapy for Bladder Cancer
Bladder cancer is a prevalent and challenging malignancy, affecting thousands of individuals worldwide each year. A groundbreaking advancement in the field of cancer therapy has the potential to transform the way we address this disease – photothermal therapy (PTT). As a premier preclinical CRO, Alfa Cytology offers comprehensive services in the development and evaluation of PTT-based treatments for bladder cancer.
Introduction to Photothermal Therapy
Bladder cancer is a complex and persistent disease that has long posed significant challenges for healthcare professionals. Conventional treatment approaches, such as surgery, chemotherapy, and radiation, have had limited success, often leading to significant side effects and suboptimal outcomes. PTT harnesses the power of light-absorbing nanomaterials to selectively destroy cancer cells, while leaving healthy tissues unharmed.

At the core of PTT are strategically engineered nanomaterials, such as gold nanoparticles, carbon nanotubes, and metal-organic frameworks, that can efficiently convert near-infrared (NIR) light energy into localized heat. When these nanomaterials are selectively accumulated within bladder tumors, the application of NIR light triggers a controlled thermal ablation, inducing the death of cancer cells through apoptosis and necrosis.
Compared to traditional therapy, PTT offers several key advantages:
