Photodynamic therapy (PDT) is a form of phototherapy involving light and a photosensitizing chemical substance, used in conjunction with molecular oxygen to elicit cell death (phototoxicity).
δ-Aminolevulinic acid, an endogenous non-proteinogenic amino acid, is the first compound in the porphyrin synthesis pathway, the pathway that leads to heme in mammals, as well as chlorophyll in plants.
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, and skin wound infections. Treating skin conditions such as neurodermatitis, psoriasis, acne vulgaris, and eczema with ultraviolet light is called ultraviolet light therapy.
Roswell Park Comprehensive Cancer Center is a cancer research and treatment center located in Buffalo, New York. Founded by surgeon Roswell Park in 1898, the center was the first in the United States to specifically focus on cancer research. The center is usually called Roswell Park in short. The center, which conducts clinical research on cancer as well as the development new drugs, provides advanced treatment for all forms of adult and pediatric cancer, and serves as a member of the National Comprehensive Cancer Network. Roswell Park Comprehensive Cancer Center is as of 2019, the only upstate New York facility to hold the National Cancer Institute designation of "comprehensive cancer center".
Erlotinib, sold under the brand name Tarceva among others, is a medication used to treat non-small cell lung cancer (NSCLC) and pancreatic cancer. Specifically it is used for NSCLC with mutations in the epidermal growth factor receptor (EGFR) — either an exon 19 deletion (del19) or exon 21 (L858R) substitution mutation — which has spread to other parts of the body. It is taken by mouth.
Photomedicine is an interdisciplinary branch of medicine that involves the study and application of light with respect to health and disease. Photomedicine may be related to the practice of various fields of medicine including dermatology, surgery, interventional radiology, optical diagnostics, cardiology, circadian rhythm sleep disorders and oncology.
Porfimer sodium, sold as Photofrin, is a photosensitizer used in photodynamic therapy and radiation therapy and for palliative treatment of obstructing endobronchial non-small cell lung carcinoma and obstructing esophageal cancer.
Methyl aminolevulinate (MAL) is a drug used as a sensitizer in photodynamic therapy. It is a prodrug that is metabolized to protoporphyrin IX. It is marketed as Metvix.
Tegafur/uracil is a chemotherapy drug combination used in the treatment of cancer, primarily bowel cancer. It is also called UFT or UFUR.
Temoporfin (INN) is a photosensitizer used in photodynamic therapy for the treatment of squamous cell carcinoma of the head and neck . It is marketed in the European Union under the brand name Foscan. The U.S. Food and Drug Administration (FDA) declined to approve Foscan in 2000. The EU approved its use in June 2001.
Cancer can be treated by surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy and synthetic lethality, most commonly as a series of separate treatments. The choice of therapy depends upon the location and grade of the tumor and the stage of the disease, as well as the general state of the patient. Cancer genome sequencing helps in determining which cancer the patient exactly has for determining the best therapy for the cancer. A number of experimental cancer treatments are also under development. Under current estimates, two in five people will have cancer at some point in their lifetime.
Combined small cell lung carcinoma is a form of multiphasic lung cancer that is diagnosed by a pathologist when a malignant tumor, arising from transformed cells originating in lung tissue, contains a component of;small cell lung carcinoma (SCLC), admixed with one components of any histological variant of non-small cell lung carcinoma (NSCLC) in any relative proportion.
Targeted therapy of lung cancer refers to using agents specifically designed to selectively target molecular pathways responsible for, or that substantially drive, the malignant phenotype of lung cancer cells, and as a consequence of this (relative) selectivity, cause fewer toxic effects on normal cells.
Alternating electric field therapy, sometimes called tumor treating fields (TTFields), is a type of electromagnetic field therapy using low-intensity, intermediate frequency electrical fields to treat cancer. A TTField-generating device manufactured by the Israeli company Novocure is approved in the United States and Europe for the treatment of newly diagnosed and recurrent glioblastoma multiforme (GBM), and is undergoing clinical trials for several other tumor types. Despite earning regulatory approval, the efficacy of this technology remains controversial among medical experts.
Photoimmunotherapy (PIT) is an oncological treatment that combines photodynamic therapy of tumor with immunotherapy treatment. Combining photodynamic therapy with immunotherapy enhances the immunostimulating response and has synergistic effects for metastatic cancer treatment.
Sonodynamic therapy (SDT) is a noninvasive treatment, often used for tumor irradiation, that utilizes a sonosensitizer and the deep penetration of ultrasound to treat lesions of varying depths by reducing target cell number and preventing future tumor growth. Many existing cancer treatment strategies cause systemic toxicity or cannot penetrate tissue deep enough to reach the entire tumor; however, emerging ultrasound stimulated therapies could offer an alternative to these treatments with their increased efficiency, greater penetration depth, and reduced side effects. Sonodynamic therapy could be used to treat cancers and other diseases, such as atherosclerosis, and diminish the risk associated with other treatment strategies since it induces cytotoxic effects only when externally stimulated by ultrasound and only at the cancerous region, as opposed to the systemic administration of chemotherapy drugs.
Apalutamide, sold under the brand name Erleada among others, is a nonsteroidal antiandrogen (NSAA) medication which is used in the treatment of prostate cancer. It is specifically indicated for use in conjunction with castration in the treatment of non-metastatic castration-resistant prostate cancer (NM-CRPC). It is taken by mouth.
This is a historical timeline of the development and progress of cancer treatments, which includes time of discovery, progress, and approval of the treatments.
Eva Ramón Gallegos is a Mexican scientist, professor and researcher at the Escuela Nacional de Ciencias Biológicas of the Instituto Politécnico Nacional. Her field of specialty is in biomedical sciences and nanobiotechnology. Her main line of research is the search for non-invasive treatments for the eradication of the uterine cervical cancer produced by the human papilloma virus (HPV), using photodynamic therapies.
Yu Baofa is a Chinese oncologist and researcher in intratumoral cancer therapy and drug development. He is the Founder, CEO and Chairman of Baofa Cancer Hospital Network China in Jinan, Beijing and Dongping. He also developed Ultra Minimum Incision Personalized Intra-Tumoral Chemo-Immuno (UMIPIC) Therapy.
