Abstract:
Cancer remains a major cause of death worldwide and current therapies are often limited by toxicity, resistance and poor tumor selectivity. Photodynamic therapy (PDT) offers spatiotemporally controlled cytotoxicity but its efficacy is constrained by suboptimal photosensitizer delivery, tumor heterogeneity and the context-dependent role of autophagy. In this Keynote Review, we discuss how nanomedicine can be engineered for targeted, stimuli-responsive PDT while modulating autophagic flux to overcome resistance. We further highlight how artificial intelligence, including machine learning and deep learning, can integrate multi-omics and imaging data to guide target selection, nanocarrier design and personalized, autophagy-informed PDT strategies.
Insights
This review explores using nanomedicine to enhance photodynamic therapy (PDT) for cancer treatment by improving drug delivery and targeting. Artificial intelligence aids in personalizing these advanced PDT strategies to overcome treatment resistance.
Area of Science:
- Oncology
- Nanomedicine
- Photodynamic Therapy (PDT)
- Artificial Intelligence (AI)
Background:
- Cancer is a leading global cause of death, with current treatments facing limitations like toxicity, resistance, and lack of tumor selectivity.
- Photodynamic therapy (PDT) provides controlled cancer cell killing but is hindered by poor photosensitizer delivery, tumor variability, and autophagy's complex role.
- Autophagy, a cellular process, can promote or inhibit cancer progression and treatment efficacy, necessitating its modulation in therapeutic strategies.
Purpose of the Study:
- To review advancements in engineering nanomedicine for targeted and stimuli-responsive photodynamic therapy (PDT).
- To discuss strategies for modulating autophagic flux to overcome PDT resistance in cancer.
- To highlight the role of artificial intelligence (AI) in personalizing autophagy-informed PDT.
Main Methods:
- Engineering nanocarriers for enhanced photosensitizer delivery and targeted accumulation in tumors.
- Developing stimuli-responsive nanomedicines that activate PDT upon specific triggers.
- Investigating methods to modulate autophagic flux, either inhibiting or promoting it, to enhance PDT efficacy.
- Utilizing AI, including machine learning and deep learning, to analyze multi-omics and imaging data for personalized treatment planning.
Main Results:
- Nanomedicine offers improved control over photosensitizer delivery and activation for spatiotemporally controlled PDT.
- Modulating autophagy can re-sensitize resistant tumors to PDT, improving therapeutic outcomes.
- AI integration enables the analysis of complex biological data to guide nanocarrier design and treatment personalization.
Conclusions:
- Nanomedicine-based, targeted, and stimuli-responsive PDT holds significant promise for improving cancer treatment efficacy.
- Combining nanomedicine with autophagy modulation and AI-driven personalization can overcome key challenges in current PDT.
- Future directions involve integrating multi-modal data for precise, individualized cancer therapy strategies.
