Light therapy for early mouth cancer or precancerous spots
Part of Cancer, Mouth & dental, Skin clinical trials.
This trial tests a low-cost approach to find and treat early mouth cancers or precancerous spots using a special light-activated drug (photodynamic therapy). The goal is to destroy the abnormal cells while sparing healthy tissue.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a visible spot in your mouth that is at least 1 centimeter wide and has been diagnosed as moderate or severe dysplasia, or carcinoma in situ (a very early form of cancer).
- You are generally healthy enough to do your daily activities without help (Karnofsky score above 80 or ECOG 0 or 1).
- Your blood counts, liver, and kidney function are within normal limits based on a blood test taken within the last 2 months.
- You are not pregnant, breastfeeding, or planning to become pregnant during the study.
- You do not have a history of porphyria or allergies to porphyrin drugs.
- You have not taken certain supplements (like vitamin A, beta carotene, vitamin E, selenium) or other cancer prevention drugs in the past month.

This study tests whether a light-based treatment (photodynamic therapy) works better than a vitamin D cream (calcipotriol) for treating white patches in the mouth that could become cancer. Both treatments are applied directly to the patch.
This trial uses a special light-based scanner (OCT) and artificial intelligence to help diagnose early signs of mouth cancer or precancer. It aims to see if this combination can make diagnosis easier and more accurate.
This trial tests two light-based treatments (photobiomodulation and photodynamic therapy) and a steroid cream (clobetasol) for painful oral lichen planus. The goal is to see which treatment works best to reduce mouth sores and discomfort.
This study tests a light-activated treatment (photodynamic therapy) for a very early form of skin cancer on the face. It may offer an alternative to surgery.
This trial tests two different ways of using a special light (photobiomodulation) to prevent or treat painful mouth sores caused by radiation therapy for head and neck cancers. It may help you if you have mouth or throat cancer and are about to start radiation.
This trial tests a special dye that helps surgeons see tumors more clearly during surgery, followed by a light therapy to destroy any remaining cancer cells. It is for people with advanced or returning colorectal cancer who are already scheduled for surgery.
