ROCHESTER, Minn. — A new breast cancer risk prediction model combining histologic features of biopsied breast tissue from women with benign breast disease and individual patient demographic information more accurately classified breast cancer risk than the current screening standard. Results of a Mayo Clinic study comparing the new model to the current standard, the Breast Cancer Risk Assessment Tool (BCRAT), are published in the Journal of Clinical Oncology.
ROCHESTER, Minn. — Women with atypical hyperplasia of the breast have a higher risk of developing breast cancer than previously thought, a Mayo Clinic study has found. Results of the study appear in a special report on breast cancer in the New England Journal of Medicine.

Atypical hyperplasia of the breast is a precancerous condition found in about one-tenth of the over 1 million breast biopsies with benign findings performed annually in the United States. Viewed under a microscope, atypia contains breast cells that are beginning to grow out of control (hyperplasia) and cluster into abnormal patterns (atypical). Atypia lesions are considered benign, but by its risk and appearance and genetic changes, they exhibit some of the early features of cancer.
ROCHESTER, Minn. — Clinical recommendations discouraging the use of CYP2D6 gene testing to guide tamoxifen therapy in breast cancer patients are based on studies with flawed methodology and should be reconsidered, according to the results of a Mayo Clinic study published in the Journal of the National Cancer Institute.

For years, controversy has surrounded the CYP2D6 gene test for breast cancer. Women with certain inherited genetic deficiencies in the CYP2D6 gene metabolize tamoxifen less efficiently, and thus have lower levels of tamoxifen’s active cancer-fighting metabolite endoxifen. Numerous studies have shown that these women gain less benefit from tamoxifen therapy and have higher rates of recurrence.

SAN ANTONIO — James Ingle, M.D., an internationally recognized breast cancer expert, will receive the 2014 William L. McGuire Memorial Lecture Award on Dec. 10 at the 2014 San Antonio Breast Cancer Symposium.
Dr. Ingle is a professor of oncology and the Foust Professor in the Mayo Clinic College of Medicine in Rochester, Minnesota. He has been the leader of breast cancer research at the Mayo Clinic Cancer Center, serving as program co-leader of the women's cancer program with responsibility for breast cancer. He is currently co-director of the Mayo Clinic Breast Cancer Specialized Program of Research Excellence (SPORE). SPORE grants are funded by the National Cancer Institute (NCI) and are the major NCI translational research grants in which clinicians and basic scientists work together to conduct the most promising research.
Dr. Ingle's research has had a significant impact on clinical practice. He has a long track record of leading or co-leading studies in breast cancer, first with tamoxifen and then with aromatase inhibitors, which are the two major endocrine therapies in breast cancer. More recently, Dr. Ingle has a leadership role in the Mayo Clinic Pharmacogenomic Research Network, leading multiple genome-wide association studies to investigate genetic variability in patients’ response to tamoxifen and aromatase inhibitors as well as chemotherapy. This work is central to developing precision medicine in which the right dose of the right drug is given to the right patient.
San Francisco -- Self-reported quality of life among patients diagnosed with aggressive lymphoma can predict overall survival and event-free survival, a Mayo Clinic study has found. The results were presented today at the 56th American Society of Hematology annual meeting, in San Francisco.
"We studied a large sample of patients with aggressive lymphoma and found that their baseline quality of life is predictive of overall survival and event-free survival, even after adjustment for known factors related to survival," says the study's lead author, Carrie Thompson, M.D., a hematologist at Mayo Clinic. "Our findings provide evidence that patient-reported outcomes are as important as other more objective International Prognostic Indicators (IPI) and that quality of life should be assessed at diagnosis as a prognostic factor in patients with aggressive lymphoma." IPI is a clinical tool used to help predict the prognosis of patients with aggressive lymphoma.

ROCHESTER, Minn. — A phase I clinical trial of nivolumab found that the immune-boosting drug is a highly effective therapy for Hodgkin’s lymphoma. The multi-institution study, led by Mayo Clinic, indicated that the drug was safe and led to an 87 percent response rate in patients who had failed on other treatments. Results of the study appear in the New England Journal of Medicine.
The findings support further development of nivolumab, which enhances the immune system’s ability to detect and kill cancer cells. The drug has already demonstrated benefit in the treatment of other cancers, particularly melanoma, renal cell cancer, lung cancer and bladder cancer.
“Nivolumab is a very promising agent that is reasonably well-tolerated and can easily be combined with other agents in the future,” says Stephen Ansell, M.D., Ph.D., a hematologist and co-lead author of the study. “There is evidence now that you can fight cancer by optimizing your immune function, either by enhancing signals that stimulate the immune response or blocking signals that dampen it.”
ROCHESTER, Minn. — Most patients with triple-negative breast cancer should undergo genetic testing for mutations in known breast cancer predisposition genes, including BRCA1 and BRCA2, a Mayo Clinic-led study has found. The findings come from the largest analysis to date of genetic mutations in this aggressive form of breast cancer. The results of the research appear in the Journal of Clinical Oncology.
“Clinicians need to think hard about screening all their triple-negative patients for mutations because there is a lot of value in learning that information, both in terms of the risk of recurrence to the individual and the risk to family members. In addition, there may be very specific therapeutic benefits of knowing if you have a mutation in a particular gene,” says Fergus Couch, Ph.D., professor of laboratory medicine and pathology at Mayo Clinic and lead author of the study.
The study found that almost 15 percent of triple-negative breast cancer patients had deleterious (harmful) mutations in predisposition genes. The vast majority of these mutations appeared in genes involved in the repair of DNA damage, suggesting that the origins of triple-negative breast cancer may be different from other forms of the disease. The study also provides evidence in support of the National Comprehensive Cancer Network (NCCN) guidelines for genetic testing of triple-negative breast cancer patients.
ROCHESTER, Minn. — The investigational drug ixazomib taken orally in combination with lenalidomide and dexamethasone shows promise in patients with newly diagnosed multiple myeloma, according to the results of a phase 1/2 study published in the journal Lancet Oncology.
"Ixazomib is an investigational, oral proteasome inhibitor with promising anti-myeloma effects and low rates of peripheral neuropathy," says Shaji Kumar, M.D., a hematologist at Mayo Clinic and lead author of the study. "While it is well known that a combination of bortezomib, lenalidomide and dexamethasone is highly effective in treating newly diagnosed multiple myeloma, we wanted to study the safety, tolerability and activity of ixazomib in combination with lenalidomide and dexamethasone in newly diagnosed multiple myeloma."
