“The addition of bevacizumab to adjuvant chemotherapy failed to improve survival outcomes in patients with surgically resected early-stage non–small-cell lung cancer (NSCLC), according to a new randomized trial. The agent “does not have a role” in this setting, the investigators concluded.
” ‘In the setting of advanced-stage NSCLC, the first agent to improve survival when added to a platinum doublet was bevacizumab,’ wrote authors led by Heather A. Wakelee, MD, of the Stanford Cancer Institute at Stanford University in California. The researchers tested whether the VEGF-targeted agent would be similarly effective in the early-stage NSCLC adjuvant setting, where patients remain at high risk of relapse despite chemotherapy.”
“A new randomized trial found that neoadjuvant trastuzumab/pertuzumab alone yields a substantially worse rate of pathologic complete response compared with trastuzumab/pertuzumab plus paclitaxel in women with early, HER2-positive, hormone receptor (HR)-negative breast cancer.
” ‘Pathologic complete response (pCR) after neoadjuvant [therapy] has strong prognostic impact in HER2 disease,’ wrote study authors led by Ulrike Nitz, MD, of the West German Study Group GmbH in Moenchengladbach, Germany. The WSG-ADAPT HER2+/HR− trial assessed whether dual blockade with trastuzumab and pertuzumab could achieve similar rates of pCR in those with strong early response to dual blockade along with chemotherapy.”
“Breast cancer patients who have radiotherapy targeted at the original tumour site experience fewer side effects five years after treatment than those who have whole breast radiotherapy, and their cancer is just as unlikely to return, according to trial results published* in The Lancet (link is external) today (Wednesday).
“The Cancer Research UK-funded IMPORT LOW trial** revealed that five years after treatment, almost all patients were disease free.***
“A duration of endocrine therapy beyond 5 years has gained traction in the treatment of endocrine receptor (ER)-positive early-stage breast cancer. Long-term use of aromatase inhibitors (AIs), however, may increase the risk of bone loss and bone fracture. Data suggest that the use of bone-targeted agents can substantially reduce the risk of osteoporotic complications associated with AI use, and even reduce the risk of bone recurrence in postmenopausal women with early-stage breast cancer.”
“Researchers at the University of Cincinnati (UC) College of Medicine are enrolling patients in a clinical trial looking at targeted gene therapies in patients with early stage lung cancer who have had surgery.
“This could help researchers gain insight into genetic targets that could aid in earlier intervention and better outcomes for patients.
” ‘Despite therapeutic advances in recent years, cancer remains the second leading cause of death in the United States, and effective new therapies are still desperately needed. Additionally, lung cancer is the leading cause of cancer deaths for women and for men,’ says Sandra Starnes, MD, Dr. John B. Flege Jr. Chair in Cardiothoracic Surgery, associate professor of surgery and co-director of the UC Cancer Institute’s Comprehensive Lung Cancer Center. ‘Targeted genetic therapy holds great promise for improved efficacy in treating patients. In this trial, researchers will evaluate the use of a newer targeted therapy for early stage lung cancer patients who have had surgery and completed post-operative chemotherapy.’ ”
“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.’ ”
“Genomic Health, Inc. (GHDX) announced today the presentation of results from four studies evaluating the clinical value and utility of its Oncotype DX® Genomic Prostate Score™ (GPS) in the management of early-stage prostate cancer. Collectively, these new data highlight the test’s ability to predict disease aggressiveness and refine risk stratification across National Comprehensive Cancer Network (NCCN) clinical risk groups.
” ‘We now have 22 clinical studies, involving more than 4,200 prostate cancer patients, that distinguish Oncotype DX as the only test developed specifically for men who are deciding between active surveillance or definitive treatment. The test is validated to provide individualized information about both the current state and future risk of patients’ prostate cancer,’ said Phil Febbo, M.D., chief medical officer, Genomic Health. ‘Together with the recently published economic analysis demonstrating substantial cost savings of more than $2,200 per patient tested, the data presented will support increased adoption and reimbursement of Oncotype DX as physicians aim to bring precision medicine to their prostate cancer patients.’ “
“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.”
“A prospective study is investigating whether breast cancer surgery can be eliminated in patients who respond well to neoadjuvant systemic therapy.
“The phase II single-center trial, conducted out of The University of Texas MD Anderson Cancer Center (NCT02945579), aims to determine how often breast cancer recurs in patients who previously received chemotherapy and follow-up radiation therapy, but not surgery, and have no evidence of disease. Forty patients with early-stage, triple-negative or HER2-positive breast cancer care underwent image-guided biopsy after completing chemotherapy and before beginning radiation therapy to see if surgery is necessary.”
