Abstract:
Cancer is the second leading cause of death worldwide; therefore, there is an urgent need to find safe and effective therapies. Triple-negative breast cancer (TNBC) is diagnosed in ca. 15-20% of BC and is extremely aggressive resulting in reduced survival rate, which is mainly due to the low therapeutic efficacy of available treatments. Photodynamic therapy (PDT) is an interesting therapeutic approach in the treatment of cancer; the photosensitizers with good absorption in the therapeutic window, combined with their specific targeting of cancer cells, have received particular interest. This review aims to revisit the latest developments on chlorin-based photoactive molecules for targeted therapy in TNBC. Photodynamic therapy, alone or combined with other therapies (such as chemotherapy or photothermal therapy), has potential to be a safe and a promising approach against TNBC.
Insights
New chlorin-based molecules show promise for targeted photodynamic therapy (PDT) against aggressive triple-negative breast cancer (TNBC). This approach offers a potentially safer and more effective treatment option for TNBC patients.
Area of Science:
- Oncology
- Biomedical Engineering
- Photochemistry
Background:
- Cancer remains a leading global cause of death, necessitating novel therapeutic strategies.
- Triple-negative breast cancer (TNBC) is an aggressive subtype with limited treatment options and poor survival rates.
- Photodynamic therapy (PDT) utilizes photosensitizers to target and destroy cancer cells, offering a promising avenue for treatment.
Purpose of the Study:
- To review recent advancements in chlorin-based photoactive molecules for targeted TNBC therapy.
- To explore the potential of PDT, alone or in combination, as a safe and effective treatment for TNBC.
Main Methods:
- Literature review focusing on chlorin derivatives and their application in TNBC treatment.
- Analysis of studies investigating photosensitizer properties, targeting capabilities, and therapeutic efficacy.
- Examination of PDT's role in combination therapies for enhanced outcomes.
Main Results:
- Chlorin-based photosensitizers demonstrate potential for specific targeting of TNBC cells.
- PDT exhibits promise as a standalone therapy and when combined with chemotherapy or photothermal therapy.
- Optimized photosensitizers with absorption in the therapeutic window are crucial for PDT efficacy.
Conclusions:
- Chlorin-based photoactive molecules represent a significant development in targeted TNBC therapy.
- Photodynamic therapy offers a safe and effective approach, particularly when integrated with other treatment modalities.
- Further research into these agents could lead to improved survival rates for TNBC patients.
