LASER FOR POST-RADIATION DERMATITIS


Laser may support healing process of post radiation dermatitis as you can see in the above pictures..
For nasopharyngeal cancer,the golden standard is radiation( eitther external radiation only or maybe combined with internal radiation(brachytherapy).
Most of the patients were diagnosed at the the late stage where a combination with chemotherapy were needed.
A new modality of treating nasopharyngeal cancer using laser and photosensitizer named Photodynamic Therapy is now going into popularity among cancer centers.A new generation of photosensitizer which is more potent is now available in the market.

A REPORT MORE THAN 25 YEARS AGO

More than 25 years ago,my work with Kurniawan(now professor of anatomic pathology) was publish in the official publication of The International Society for Preventive Oncology: CancerDetection and Prevention,volume 4 numbers 1-4,1981.
Our work was on the usage of an acidic metachromatic dye named toluidine blue for study of the in vivo technique for laryngeal lesions .
Our experience suggest that in vivo staining may be a useful method for early detection of laryngeal cancer used as an adjunct to microlaryngoscopy.
Now it progress to a technique of using toluidine blue as a photosensitizer in photodynamic therapy used in cancer therapy.
