What Is Oncotype DX?

Oncotype DX is the first clinically validated commercial genomic assay for patients with DCIS. Oncotype DX reveals the underlying biology that can help guide DCIS treatment decisions by predicting the risk of any local recurrence of breast cancer (DCIS or invasive) and the risk of local invasive carcinoma and allowing for personalized treatment based on tumor biology as determined by the DCIS recurrence score.

Excerpt from “Demystifying DCIS Breast Cancer: Test seeks to predict prognosis and guide treatment decisions,” by Kari Bohlke, ScD, A Woman’s Health:

The Oncotype DX breast cancer test was originally developed for use in certain groups of women with early-stage, invasive breast cancer, but it’s now possible to also use the test to generate a DCIS recurrence score—an indicator of the likelihood that DCIS will recur after treatment with lumpectomy alone.

Results from a study of the DCIS score were recently presented at the 34th Annual CTRC-AACR San Antonio Breast Cancer Symposium.3 The study involved 327 women with DCIS who had participated in an earlier clinical trial of DCIS treatment. The women had been treated with lumpectomy but had not received radiation therapy.

Three-quarters of the patients had a low risk of recurrence based on the DCIS score. For these women the likelihood of any kind of local recurrence (either DCIS or invasive breast cancer) was 12 percent, and likelihood of a recurrence that involved invasive breast cancer was 5 percent. By comparison, among women with a high risk of recurrence based on the DCIS score, the likelihood of any kind of local recurrence was 27 percent, and the likelihood of a recurrence that involved invasive breast cancer was 19 percent.

These results suggest that the Oncotype DX DCIS score provides information about the risk of recurrence after breast-conserving surgery for DCIS. This information could help guide decisions about the need for postoperative radiation therapy following treatment with lumpectomy. Research in genomics is expanding at a rapid rate and will have a profound effect on many aspects of disease prevention, diagnosis, and treatment. Diseases such as cancer are remarkably complex; genomics provides researchers and physicians with tools to explore and address these complexities and help individualize treatment decisions.

About dp4peace

I was born and raised in New Jersey and moved to the San Fernando Valley of Los Angeles when I was 12. I graduated with a BA in Journalism/Advertising from San Diego State University. After a short stint in magazine ad sales in LA, I was offered my dream job working for Club Med. I spent two years working at resorts in Mexico, The Bahamas, The Dominican Republic and Colorado. My husband Glenn & I met while working at Club Med in Ixtapa, Mexico. We returned to "real life/jobs" for three years before we embarked on a two year honeymoon around the world. Together we wrote a book called "When The Travel Bug Bites: Creative Ways to Earn, Save and Stay Abroad." I am also the author of "Cheatnotes on Life: Lessons From The Classroom of Life," a quote book for new graduates. Glenn & I live in San Diego with our two boys: Skyler, the yogi and Cody, the buddha! I enjoy running, yoga and working on projects that bring more peace, health and light to our world.
