“The combination of immunotherapy and chemotherapy is showing promising response rates in certain patients with triple-negative breast cancer (TNBC), said ESO Umberto Veronesi Memorial Award Winner Giuseppe Curigliano, MD, PhD, who addressed genetic determinants of breast cancer immunogenicity in his award lecture at the 15th St. Gallen International Breast Cancer Conference.
“Curigliano emphasized the importance of patient selection in optimizing immunotherapy in breast cancer. In a study done by Curigliano, in collaboration with the Sidra Medical Center in Qatar, a subgroup of patients with TNBC who would derive benefit from checkpoint inhibitors were identified. This group, he stated, should be selected based on individual assessment of tumor-infiltrating lymphocytes.”
“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.’ ”
“Adding temozolomide chemotherapy to short-course radiotherapy for older patients with glioblastoma was tied to longer progression-free and overall survival than with a short course of radiotherapy alone, researchers found.
“In a randomized controlled trial of glioblastoma patients ages 65 and up, those on combination therapy had a significantly lower risk of death during the study than those who had only radiation (HR 0.67, 95% CI 0.56-0.80, P<0.001), James Perry, MD, of Sunnybrook Research Institute in Toronto, and colleagues reported in the New England Journal of Medicine.”
“The MEK inhibitor binimetinib improved progression-free survival compared with dacarbazine in patients with NRAS-mutant melanoma, according to the phase III results of the NEMO trial published in Lancet Oncology.
“In addition, improved progression-free survival was seen in patients who had previously failed immunotherapy, the current guideline-recommended first-line treatment.
” ‘Future treatment algorithms for metastatic melanoma might incorporate binimetinib therapy in patients with advanced NRAS-mutant melanoma, including after the failure of immunotherapy,’ wrote Reinhard Dummer, MD, of the department of dermatology at the University Hospital Zurich Skin Cancer Center in Switzerland, and colleagues.”
“An emerging approach for cancer treatment seeks to combine radiation therapy with immune checkpoint inhibitors (ICPIs) to more effectively control tumors in the chest with an acceptable risk of severe treatment-related side effects. Ten percent of patients in a retrospective analysis of metastatic lung cancer experienced severe toxicity as a result of the combination therapy. Findings will be presented tomorrow at the 2017 Multidisciplinary Thoracic Cancers Symposium.”
“New research led by a radiation oncologist at Roswell Park Cancer Institute indicates that less may be more when it comes to some forms of radiation therapy for cancer. In a presentation highlighted in a plenary session today at the Multidisciplinary Thoracic Cancers Symposium in San Francisco, California, Anurag Singh, MD, shared updated evidence that patients receiving stereotactic body radiation therapy (SBRT) as treatment for non-small cell lung cancer (NSCLC) benefit as much from a single fraction, or dose, of radiation as they would from the standard three-dose treatment schedule — and with significant advantages in terms of convenience for patients and caregivers.”
“The genetic mutations underlying treatment resistance in non-small cell lung cancer (NSCLC) are more complex and dynamic than previously thought. Analysis of 355 biopsied tumors from patients who acquired resistance to EGFR inhibitors, the most common form of targeted therapy for NSCLC, found that mutations frequently varied between biopsies and that nearly one in five patients harbored more than one type of genetic resistance to treatment. Findings will be presented today at the 2017 Multidisciplinary Thoracic Cancers Symposium.”
“Results from a prospective clinical trial showed that a blood test looking at specific biomarkers was able to detect recurrences of lung cancer an average of six months before conventional imaging methods found evidence of recurrence. In the largest prospective clinical trial to date of circulating tumor cells (CTC) as biomarkers for locally advanced lung cancer, the findings indicate that blood tests potentially can be used in conjunction with CT and PET/CT scans to guide personalized treatment planning for patients with non-small cell lung cancer (NSCLC). The study will be presented today at the 2017 Multidisciplinary Thoracic Cancers Symposium.”
“Hair loss—one of the most-feared side effects of cancer treatment—may have met its match. Scientists have known since the 80s that cooling a person’s scalp can prevent significant hair loss during chemotherapy. A cooling device called DigniCap was approved for women with breast cancer by the U.S. Food and Drug Administration in 2015. This cap was tested in a clinical trial at UCLA led by Dr. Sara Hurvitz, director of hematology and oncology breast cancer program at UCLA’s Jonsson Comprehensive Cancer Center.
“Two studies published this month in the Journal of the American Medical Association found that the cap was effective; results showed that women lost less than 50 percent of their hair. The trial Hurvitz participated in paved the way for physicians to help people with cancer overcome one of the most visible signs of treatment.”
