Summary
This review explores nanoparticle-based phototherapy for cancer. Nanoparticles enhance drug delivery and combine with light to eradicate tumors, potentially boosting the immune system for lasting antitumor effects.
Area of Science:
- Oncology
- Nanotechnology
- Immunotherapy
Background:
- Phototherapy is an emerging cancer treatment that uses light irradiation to activate therapeutic agents at tumor sites.
- Photothermal and photodynamic agents, delivered via nanoparticles, induce hyperthermia and reactive oxygen species to eliminate cancer cells.
- Nanoparticles offer improved biocompatibility and targeted delivery of phototherapeutic agents, with potential for codelivery strategies.
Purpose of the Study:
- To review recent advancements in nanoparticle-based phototherapy for cancer treatment.
- To highlight the integration of nanoparticle technology with phototherapy to enhance antitumor responses.
- To discuss the potential of nanoparticle-mediated phototherapy in augmenting immunological effects for systemic treatment.
Main Methods:
- Review of current literature on nanoparticle applications in phototherapy.
- Analysis of strategies for codelivery of agents using nanocarriers.
- Examination of studies focusing on the immunological impacts of nanoparticle-based phototherapies.
Main Results:
- Nanoparticles effectively deliver phototherapeutic agents, improving efficacy and targeting.
- Codelivery strategies using nanocarriers can further enhance phototherapeutic outcomes.
- Emerging evidence suggests nanoparticle-based phototherapies can stimulate systemic antitumor immunity.
Conclusions:
- Nanoparticle technology is pivotal in advancing phototherapy for cancer.
- Combining phototherapy with immunotherapy via nanoparticles shows promise for durable, systemic antitumor effects.
- Further research into nanoparticle-mediated photo-immunotherapy is warranted for clinical translation.

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.

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
