“In an analysis of long-term outcomes in the SOFT and TEXT trials reported at the 2018 ASCO Annual Meeting and in The New England Journal of Medicine, Francis et al found that the addition of ovarian suppression to adjuvant tamoxifen significantly improved 8-year rates of disease-free and overall survival vs tamoxifen alone among premenopausal women with breast cancer; risk of recurrence was further reduced with exemestane plus ovarian suppression.
“Initial reports showed that 5-year rates of recurrence were significantly lower among premenopausal women who received the aromatase inhibitor exemestane plus ovarian suppression vs tamoxifen plus ovarian suppression, with the addition of ovarian suppression to tamoxifen not significantly improving recurrence risk vs tamoxifen alone.”
“A one-year course of 18 doses of pembrolizumab (Keytruda) significantly reduced the risk of recurrence for patients with stage 3 melanoma who were at high risk of recurrence after surgery, according to data from the KEYNOTE-054/EORTC 1325-MG phase III clinical trial, presented at the AACR Annual Meeting 2018, April 14–18.
“Myriad Genetics, Inc. (MYGN) today announced that a comparative analysis of commercially available prognostic breast cancer tests in patients with early-stage breast cancer has been published in JAMA Oncology. A key finding is that Myriad’s EndoPredict® (EPClin) significantly outperformed Oncotype DX® Recurrence Score at predicting the risk of disease recurrence in patients with early-stage breast cancer.
“In the article, Sestak et al. compared the prognostic value that four different commercial tests add to the Clinical Treatment Score (nodal status, tumor size, grate, age, endocrine treatment) for predicting distant recurrence (0-10 years) and late-distant recurrence (5-10 years) of breast cancer. The analysis included data from 774 postmenopausal women with ER+/HER2- breast cancer with node-negative disease or up to three positive lymph nodes, which is the most common form of breast cancer.”
“Breast cancer can ‘smolder’ and return even 20 years later unless patients keep taking drugs to suppress it, researchers reported Wednesday.
“They were looking for evidence that at least some breast cancer survivors might be able to skip the pills that reduce the risk of the breast tumors coming back, but found that even women with ‘low-risk’ cancers had a small rate of recurrence 15 and 20 years later.”
“The U.S. Food and Drug Administration today approved Nerlynx (neratinib) for the extended adjuvant treatment of early-stage, HER2-positive breast cancer. For patients with this type of cancer, Nerlynx is the first extended adjuvant therapy, a form of therapy that is taken after an initial treatment to further lower the risk of the cancer coming back. Nerlynx is indicated for adult patients who have been previously treated with a regimen that includes the drug trastuzumab.”
“A novel risk stratification tool that combines pathologic tumor characteristics with data from the Decipher genomic classifier may help predict 5- and 10-year metastasis-free survival in patients with aggressive prostate cancer after radical prostatectomy with an accuracy of 85%, researchers reported.
“It can also be used to identify patients with prostate cancer who could benefit from postoperative adjuvant radiotherapy (aRT), thereby reducing risk of overtreatment, adverse effects, and clinical recurrence (CR), Firas Abdollah, MD, of Vattikuti Urology Institute at the Henry Ford Health System in Detroit, and colleagues reported online in the Journal of Clinical Oncology.”
“Women with early-stage breast cancer and an intermediate risk recurrence score from a 21-gene expression assay may be able to avoid chemotherapy, according to a retrospective study published in Cancer.
” ‘Through years of research discoveries, it became clear that we were overtreating many women with breast cancer, especially those with early-stage breast cancer,’ Carlos H. Barcenas, MD, assistant professor of breast medical oncology at The University of Texas MD Anderson Cancer Center, said in a press release. ‘In addition to chemotherapy’s obvious side effects, there were also long-term complications for these women as survivors.’ ”
“Women with early-stage breast cancer who had an intermediate risk recurrence score (RS) from a 21-gene expression assay had similar outcomes, regardless of whether they received chemotherapy, a new study from The University of Texas MD Anderson Cancer finds.
“The encouraging research, published in the journal CANCER, still needs to be validated in an ongoing international trial. If verified, women with intermediate scores may one day be able to avoid chemotherapy as standard of care.”
