The research shows that this risk is greatly influenced by the treatment the woman receives. The study is published in the International Journal of Radiation Oncology.
Previous studies have shown that younger breast cancer patients consistently have poorer outcomes than patients who develop the disease later in life, which can translate into lower rates of overall survival. While the reason for this is not known, it is suggested that breast cancer in younger patients is more biologically aggressive.
Researchers from the University of Texas M.D. Anderson Cancer Center in Houston sought to determine which form of breast cancer treatment - breast-conserving therapy, mastectomy alone or mastectomy with adjuvant radiation - better benefits younger women with either Stage I or Stage II breast cancer.
A total of 652 young women with breast cancer from 1973 to 2006 were studied, with 197 of the patients having received breast-conserving therapy, 237 having received a mastectomy and 234 having received mastectomy with adjuvant radiation. The study authors confirmed that younger breast cancer patients do have relatively high locoregional recurrence rates, but that patients with Stage II disease achieved the best locoregional control rates with mastectomy plus adjuvant radiation therapy. Patients with Stage I disease had similar outcomes with breast-conserving therapy and mastectomy, but adding chemotherapy to either treatment was beneficial.
ASTRO is the largest radiation oncology society in the world, with more than 10,000 members who specialize in treating patients with radiation therapies. As the leading organization in radiation oncology, biology and physics, the Society is dedicated to improving patient care through education, clinical practice, advancement of science and advocacy.
