A study published in JAMA Oncology raises more questions regarding appropriate treatments for ductal carcinoma in-situ (DCIS). I wrote about surgery for DCIS about a month ago. The controversy continues.
The JAMA Oncology study by Dr. Steven Narod and colleagues used the SEER Database to try to determine if treatment for DCIS improves the death rate. They found that breast cancer-specific mortality was approximately 3.3% over a 20 year period, a very low rate. Certain patient populations such as women under the age of 40, African Americans, and patients with ER-negative and more aggressive subtypes of DCIS had higher mortality rates.
This study has led to headlines including Doubt is Raised over the Value of Surgery for Breast Lesion at Earliest Stage (New York Times, New Breast Cancer Study Raises Questions, Delivers Few Answers (NBC News), Study Sparks Debate on Treatment for Early Stage Breast Cancer (USA Today) and Early Stage Breast Cancer Not a Death Sentence (WebMD). Evaluation of the news coverage by Health News Review provided some context. Linked below are the comments of several experts.
