Carcinoma In Situ

While most Mohs surgeons agree on diagnostic differentiations between actinic keratosis and squamous cell carcinoma in situ, variability exists in the interpretation of in situ carcinoma on histological frozen sections, according to a study.

Neoadjuvant photodynamic therapy before surgery for squamous cell carcinoma in situ may facilitate simpler surgical interventions, according to a presentation at the American Society for Dermatologic Surgery annual meeting.

In this video, Jame Abraham, MD, director of breast oncology at Cleveland Clinic, highlighted the results from the NSABP B-43 trial that included radiation therapy efficacy with or without trastuzumab in women with ductal carcinoma in situ who have undergone lumpectomy.
