Combining liver cancer treatments doubles survival rates, UVA researchers find
By combining the use of stents and photodynamic therapy, also called SpyGlass, physicians at the University of Virginia have been able to significantly increase survival rates for patients suffering from advanced cholangiocarcinoma, cancer of the liver bile duct. view more (2008-04-16)
METVIX PHOTODYNAMIC THERAPY (PDT) SUPERIOR TO CRYOTHERAPYIN THE TREATMENT OF ACTINIC KERATOSIS (AK)
Positive Results From a Large Scale Phase III Study in Australia PhotoCure ASA has recently completed a large scale phase III clinical trial in Australia, where more than 800 pre-cancerous skin lesions (actinic keratosis or “sun spots”) caused by sun damage, in over 200 patients were studied. A novel photodynamic therapy, was compared... view more... (2001-01-15)
Photodynamic therapy as alternative therapy for periodontal diseases may be beneficial
Photodynamic therapy (PDT) may be an effective way to treat the bacteria associated with periodontal diseases, and could provide a better option than antibiotics or other mechanical methods for treating periodontal diseases, according to a new study published in the March issue of the Journal of Periodontology. view more (2007-03-07)
Photodynamic Therapy Is an Alternative to Removal of Esophagus
When you think of heartburn, you probably think of greasy food, not cancer. You may not know that chronic heartburn is linked to esophageal cancer. view more (2006-04-06)
Combined stenting and photodynamic therapy improves survival in late stage liver cancer patients
A combined therapeutic approach of stenting and photodynamic therapy may improve survival rates for patients suffering from advanced liver bile duct cancer, according to a study published this month in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association (AGA) Institute. view more (2008-03-12)
New on-off 'switch' triggers and reverses paralysis in animals with a beam of light
In an advance with overtones of Star Trek phasers and other sci-fi ray guns, scientists in Canada are reporting development of an internal on-off "switch" that paralyzes animals when exposed to a beam of ultraviolet light. view more (2009-11-19)
A sticky business -- how cancer cells become more 'gloopy' as they die
The viscosity, or 'gloopiness', of different parts of cancer cells increases dramatically when they are blasted with light-activated cancer drugs, according to new images that provide fundamental insights into how cancer cells die, published in Nature Chemistry today (15 March). view more (2009-03-16)
A new technique for curing blindness, squeezing a thousand DVDs into a matchbox and finding the missing link in optoelectronics – all covered in the January/February issue of Opto and Laser Europe
CURING BLINDNESS Age related macular degeneration (ARMD) is the principal cause of blindness for patients over 50 in the developed world. A new drug has recently been given approval for use in photodynamic therapy to treat this condition in Europe and the US. Photodynamic therapy, where a combination of injected drugs are stimulated by laser... view more... (2001-01-18)
The Light Is Fighting Cancer
The light helps physicians of the Gertsen Moscow Scientific Research Oncological Institute to fight cancer. The division headed by Professor Sokolov closely collaborates with the department of optical spectroscopy, Prokhorov Institute of General Physics, Russian Academy of Sciences, headed by Professor Smirnov, Doctor of Science... view more...

Photodynamic therapy effective for certain head and neck cancers
A combination of medications and a particular light therapy is effective at treating certain types of head and neck cancers in subtropical climates. view more (2009-10-05)
Photodynamic therapy: an effective treatment for head and neck cancers
A therapy that activates light sensitive drugs represents a major advance in the treatment of head and neck cancer, a consultant surgeon said today. (Monday 22 October 2001) Known as Foscan photodynamic therapy (PDT) 1, it is an "effective and well tolerated treatment" and can be administered without surgery, said Mr Colin Hopper of the National... view more...

Novel light-sensitive compounds show promise for cancer therapy
Chemists at the University of California, Santa Cruz, have developed novel compounds that show promise for photodynamic cancer therapy, which uses light-activated drugs to kill tumor cells. view more (2009-06-17)
Evidence for warts treatments is weak
Apart from topical treatments containing salicylic acid, there is currently no clear evidence that any other treatments for warts are more effective, say researchers in this week’s BMJ. view more (2002-08-28)
Light therapy could be a new approach to treating patients with pancreatic cancer
Pancreatic cancer is notoriously difficult to treat, largely because of the location of the pancreas close to major arteries and vital organs, and the effects of a poorly functioning pancreas on the rest of the body. It is one of the top 10 leading causes of death from cancer worldwide, and in the UK kills around 6500 people every year. view more (2002-03-11)
U-M researchers use nanoparticles to target brain cancer
Tiny particles one-billionth of a meter in size can be loaded with high concentrations of drugs designed to kill brain cancer. view more (2006-11-15)
Cancer drug delivery research at Case Western Reserve University cuts time from days to hours
Researchers at Case Western Reserve University have developed a technique that has the potential to deliver cancer-fighting drugs to diseased areas within hours, as opposed to the two days it currently takes for existing delivery systems. view more (2008-07-23)
Slide Projector Kills Herpes Simplex Virus
A lot of people suffer from herpes for all their lives. The herpes simplex virus (Type 1) constantly inhabits the organism revealing its presence from time to time. Once highly active anti- herpes drugs were developed (acyclovir and phosofonoacetic acids), the virus responded with new forms resistant to theses drugs. The Belorus researchers from... view more...

Firefly Light Helps Destroy Cancer Cells
Could the gentle firefly turn out to be a potent weapon against cancer? In a new study, researchers from London inserted the firefly gene that activates bioluminescent light into modified cancer cells, hoping to set off a chain of events that has a proven track record at fighting the disease. This light source, known as Luciferin, caused the... view more... (2003-04-11)
Light powered platinum more targeted & 80 times more powerful than similar cancer treatments
Researchers from the Universities of Warwick, Edinburgh, Dundee and the Czech Republic's Institute of Biophysics have discovered a new light-activated platinum-based compound that is up to 80 times more powerful than other platinum-based anti-cancer drugs and which can use "light activation" to kill cancer cells in much more targeted way... view more...
