Abstract Multimodal therapy often demonstrates superior therapeutic effects compared to monotherapy. Phototherapy is a promising approach for cancer treatment, as it can induce tumor pyroptosis and activate antitumor immune responses. However, mitochondrial oxidative stress during frequently stimulates protective autophagy in cells, thereby seriously impeding the progress of pyroptosis. Therefore, developing that enhances through inhibiting critical improving treatment efficacy. In this study, photoactivated mitochondrial‐targeting self‐assembled nanomicelle ( 3M@C ) integrates an aggregation‐induced emission photosensitizer inhibitor chloroquine designed. generate both type I II reactive oxygen species heat under light exposure, inducing dysfunction triggering pyroptosis, achieving photodynamic synergistic photothermal therapy. Meanwhile, inhibit mitophagy, further enhance effects, vivo experiments demonstrate strategy exhibits excellent biosafety significant efficacy, effectively suppressing growth. addition, method nanomicelles mitophagy inhibition providing novel photoimmunotherapy.

Prostate cancer is a worldwide health concern in men, with substantially high incidence rate and advanced metastatic disease-related mortality rates. Despite advancements diagnostics treatment options, conventional therapies for prostate cancer, including surgery, radiotherapy, chemotherapy androgen deprivation therapy, face limitations such as resistance, limited precision off-target side-effects. Hence, identification clinical translation of novel therapeutic strategies urgently needed. In this regard, phototherapies, photodynamic therapy (PDT) photothermal (PTT), are emerging promising options addressing the challenges associated options. Utilizing near-infrared (NIR) light to selectively target cells, these approaches spare healthy tissues. PDT employs photosensitizers produce reactive oxygen species, thereby stimulating anti-tumor immune responses, disrupting tumor microvasculature and/or inducing aopotitic or necrotic cell death. contrast, PTT leverages agents generate localized hyperthermia, achieving effective thermal ablation cells. Recent nanoparticle technology have significantly improved efficacy specificity phototherapies. Functionalized nanoparticles, those targeting prostate-specific membrane antigen (PSMA), enhance delivery, reducing systemic toxicity. Combination incorporating modalities, immunotherapy, demonstrated synergistic effects, leading better sensitization. Preclinical studies underline potential multimodal outcomes, particularly castration-resistant cancer. This review explores recent innovations illuminating their combination therapies, global burden.
