The potential of photodynamic therapy in current breast cancer treatment methodologies

Biomedicine & Pharmacotherapy, Journal Year: 2021, Volume and Issue: 137, P. 111302 - 111302

Published: Jan. 29, 2021

Photodynamic Therapy (PDT) has been known for over a hundred years, and currently gaining in acceptance as an alternative cancer treatment. Light delivery is still difficult problem deep treatment with PDT. Only near-infrared light the 700−1100 nm range can penetrate deeply into tissue because most chromophores, including oxyhemoglobin, deoxyhemoglobin, melanin fat, poorly absorb near infrared window. The sources used PDT are lasers, arc lamps, light-emitting diodes fluorescent lamps. many different clinical applications. may be excellent diagnosis of breast compared to conventional surgery, chemotherapy radiotherapy. basic elements appropriate photosensitizer (PS), oxygen, light. effectiveness photodynamic therapy depends on induction photocytotoxic reactions, which result activation PS), pre-administered body. condition initiating processes absorption by PS subsequent localized generation cytotoxic reactive oxygen species.

Progress in Clinical Trials of Photodynamic Therapy for Solid Tumors and the Role of Nanomedicine

Cancers, Journal Year: 2020, Volume and Issue: 12(10), P. 2793 - 2793

Published: Sept. 29, 2020

Current research to find effective anticancer treatments is being performed on photodynamic therapy (PDT) with increasing attention. PDT a very promising therapeutic way combine photosensitive drug visible light manage different intense malignancies. has several benefits, including better safety and lower toxicity in the treatment of malignant tumors over traditional cancer therapy. This reasonably simple approach utilizes three integral elements: photosensitizer (PS), source light, oxygen. Upon irradiation particular wavelength, PS generates reactive oxygen species (ROS), beginning cascade cellular death transformations. The positive impact may be limited because factors this include low solubilities PSs, restricting their administration, blood circulation, poor tumor specificity. Therefore, utilizing nanocarrier systems that modulate pharmacokinetics (PK) pharmacodynamics (PD) bypassing these challenges. In present paper, we review latest clinical studies preclinical vivo use progress made nanotherapeutics as delivery tools for PSs improve uptake toxic properties and, therefore, PDT. We also discuss effects photoimmunotherapy (PIT) might have solid strategies.

Reactive Oxygen Species-Based Nanomaterials for Cancer Therapy

Frontiers in Chemistry, Journal Year: 2021, Volume and Issue: 9

Published: April 22, 2021

Nanotechnology advances in cancer therapy applications have led to the development of nanomaterials that generate cytotoxic reactive oxygen species (ROS) specifically tumor cells. ROS act as a double-edged sword, they can promote tumorigenesis and proliferation but also trigger cell death by enhancing intracellular oxidative stress. Various function increasing production cells thereby disturbing their redox balance, leading lipid peroxidation, damage DNA proteins. In this review, we outline these mechanisms, summarize recent progress ROS-based nanomaterials, including metal-based nanoparticles, organic chemotherapy drug-loaded nanoplatforms, highlight biomedical drug delivery systems (DDSs) or combination with chemodynamic (CDT), photodynamic (PDT), sonodynamic (SDT). Finally, discuss advantages limitations current ROS-mediated used speculate on future nanotechnology for oncological applications.

Metal Nanoparticles for Photodynamic Therapy: A Potential Treatment for Breast Cancer

Molecules, Journal Year: 2021, Volume and Issue: 26(21), P. 6532 - 6532

Published: Oct. 29, 2021

Breast cancer (BC) is the most common malignant tumor in women worldwide, which seriously threatens women's physical and mental health. In recent years, photodynamic therapy (PDT) has shown significant advantages treatment. PDT involves activating photosensitizers with appropriate wavelengths of light, producing transient levels reactive oxygen species (ROS). Compared free photosensitizers, use nanoparticles shows great terms solubility, early degradation, biodistribution, as well more effective intercellular penetration targeted cell uptake. Under current circumstances, researchers have made promising efforts to develop nanocarrier photosensitizers. Reasonably designed photosensitizer (PS) can be achieved through non-covalent (self-aggregation, interfacial deposition, polymerization or core-shell embedding adsorption) covalent (chemical immobilization coupling) processes accumulate certain tumors passive and/or active targeting. These PS loading methods provide chemical stability payload. Among nanoparticles, metal high stability, adjustable size, optical properties, easy surface functionalization, making them biocompatible biological applications. this review, we summarize development application status for breast cancer, especially latest developments nanocarriers PDT, highlight some synergistic therapies, hopefully providing an accessible overview knowledge that may act a basis new ideas systematic evaluations already results.

Recently, several studies have indicated an increased interest in the scientific community regarding application of Cannabis sativa plants, and their extracts, for medicinal purposes. This plant enormous potential has been legalised increasing number countries globally. Due to recent changes therapeutic recreational legislation, cannabis cannabinoids are now frequently permitted use clinical settings. However, with highly lipophilic features very low aqueous solubility, prone degradation, specifically solution, as they light-, temperature-, auto-oxidation-sensitive. Thus, plant-derived developed oral, nasal-inhalation, intranasal, mucosal (sublingual buccal), transcutaneous (transdermal), local (topical), parenteral deliveries. Among these administrations routes, topical transdermal products usually a higher bioavailability rate prolonged steady-state plasma concentration. Additionally, eliminate psychotropic impacts drug by its diffusion into nonreactive, dead stratum corneum. modality avoids oral administration and, thus, first-pass metabolism, leading constant cannabinoid levels. review article investigates practicality delivering via skin accordance existing literature.
