PDT Cancer Case Study #1: Invasive Squamous Cell Carcinoma Cured In 6 Weeks

This is a case study by Dr. Merrill Biel of a 69 year old male presenting with a history of right mouth soreness for the past six months. This patient has no history of sore throat, dysphagia, hemoptysis or shortness of breath. He is a smoker (2 ppd for the past 50 years) and drinks two alcoholic beverages per day.

During his mouth examination, irregular cobblestoned mucosa of the entire right floor of the mouth was found (Figure 1). There were three areas each 1 cm in diameter of invasive firm nodules. Biopsies were then obtained and it was determined that the patient had invasive squamous cell carcinoma.  He was staged as a T3N0 superficial squamous cell cancer of the right floor of mouth and ventral tongue.
