Summary
A novel nanocomposite enhances sonochemotherapy for muscle-invasive bladder cancer (MIBC). This approach uses ultrasound to boost chemotherapy effectiveness, improving drug delivery and tumor suppression with a good safety profile.
Area of Science:
- Biomedical Engineering
- Nanotechnology
- Oncology
Background:
- Intravesical chemotherapy is limited for muscle-invasive bladder cancer (MIBC) due to poor drug penetration.
- Sonochemotherapy (SCT) offers potential but faces challenges with reactive oxygen species (ROS) generation and sonosensitizer stability.
Purpose of the Study:
- To develop a stable nanocomposite for enhanced sonochemotherapy in MIBC.
- To improve drug delivery, ROS production, and therapeutic efficacy against bladder tumors.
Main Methods:
- A MoN/Au/cTAT nanocomposite was synthesized by conjugating cisplatin and cTAT onto MoN/Au nanosheets.
- The nanocomposite's cytotoxicity was evaluated against bladder cancer cells under ultrasound irradiation.
- In vivo efficacy and safety were assessed in orthotopic bladder tumor models.
Main Results:
- MoN/Au/cTAT demonstrated significant cytotoxicity against bladder cancer cells upon ultrasound exposure.
- The nanocomposite effectively suppressed muscle-invasive orthotopic bladder tumors in vivo.
- A high safety margin was maintained during in vivo treatment.
Conclusions:
- The developed nanosonosensitizer-chemodrug platform shows promise for MIBC treatment.
- Combining cTAT for enhanced delivery with MoN/Au for ROS generation offers a transformative therapeutic strategy.
- This approach overcomes limitations of traditional intravesical chemotherapy for advanced bladder cancer.

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
02:49Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

02:50Combination Therapies and Personalized Medicine
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
