This study will assess safety and ergonomics/engineering design of a novel cancer treatment, Continuous Low Irradiance Photodynamic therapy (CLIPT). We will assess the effects on primary and metastatic tumors involving the skin, in particular to improve the functionality, efficiency and wearability of the light delivery device (LDD) as well as the overall treatment in subjects with chest wall recurrences of breast cancer. An ongoing study (IRB# 8227), sponsored by a Susan G. Komen Breast Cancer Foundation grant, using a 1st generation LDD device has evaluated and determined a dose-limiting toxicity of CLIPT for subjects with chest wall recurrences of breast cancer.
A Diomed laser will be the device used in this study. The Diomed laser will deliver 630 nm (red spectrum) light through a Fiber Optic Patch. The Fiber Optic patch will be compatible with the laser, delivering light to a designated region on the patient's skin.
