Expert Tackles Efficacy of PD-L1 Testing for NSCLC in 2017

Excerpt:

“In 2017, a lung cancer diagnosis must be accompanied by biomarker testing, whether it be for a genomic alteration, such as EGFR, ALK, or ROS1, or the immune marker PD-L1, according to Daniel B. Costa, MD, PhD, MMSc.

“Moreover, even with FDA-approved agents designed to target these abnormalities or expression levels, researchers are still hoping to uncover additional markers and match novel therapies to them.”

More Women With Breast Cancer Opt to Remove Healthy Breast

Excerpt:

“One in three breast cancer patients under 45 removed the healthy breast along with the breast affected by cancer in 2012, a sharp increase from the one in 10 younger women with breast cancer who had double mastectomies eight years earlier, a new study reports.

“The rate is especially high in some parts of the country, the study in JAMA Surgery found. Nearly half of younger women in five neighboring states — Nebraska, Missouri, Colorado, Iowa and South Dakota — had double mastectomies in 2010-12. Women often remove the healthy breast so they don’t have to worry about developing another cancer, even though there is no evidence that removing the healthy breast extends lives.”

Oncotype DX® Predicts 10-year Risk of Developing Metastatic Prostate Cancer in Low- and Intermediate-risk Patients

Excerpt:

“Genomic Health, Inc. (Nasdaq: GHDX) today announced the presentation of new results from a large multi-center validation study, which confirmed that the Oncotype DX® Genomic Prostate Score™ (GPS) is a strong independent predictor of metastases at 10 years in prostate cancer patients across all National Comprehensive Cancer Network (NCCN) clinical risk groups. The clinical validation study data were designated one of the ‘best posters’ (abstract #352) at the 32nd Annual European Association of Urology (EAU) Congress in London.”

Osimertinib Approved in China for EGFR T790M+ NSCLC

Excerpt:

“The China Food and Drug Administration (CFDA) has approved osimertinib for the treatment of patients with locally-advanced or metastatic EGFR T790M-positive non–small cell lung cancer (NSCLC) with progression following treatment with an EGFR tyrosine kinase inhibitor (TKI).

“Osimertinib was approved under the CFDA’s accelerated Priority Review Pathway. To receive the treatment, patients must have their EGFR T790M mutation status confirmed through a validated test.”

Study Provides Path for New Immunotherapy Approaches to Prostate Cancer

Excerpt:

“Prostate cancer, notoriously resistant to immunotherapy due to its immunologically cool nature, triggers two pathways to chill an immune attack after one immunotherapy drug fires up the immune system, researchers at The University of Texas MD Anderson Cancer Center report in Nature Medicine.

“Based on their findings, the researchers launched a clinical trial for stage IV in March combining two drugs that target separate brakes on the immune system. The checkpoint inhibitors largely failed individually against the disease. Their results also implicate for the first time on a human tumor a third brake called VISTA in potentially inhibiting .”

Pembrolizumab Affords Long-Term Survival to One-Fourth of Selected Patients With NSCLC, Alternative Statistical Model Suggests

Excerpt:

“Statistical modeling of long-term survival from the KEYNOTE trials of the programmed cell death protein 1 (PD-1)–inhibitor pembrolizumab ­(Keytruda) estimates that one-quarter of appropriately selected patients with advanced non–small cell lung cancer (NSCLC) may attain long-term survival.

” ‘In the context of the pembrolizumab program, these are the furthest-out data that we have so far, and I think they represent a remarkable step forward,’ commented Matthew D. Hellmann, MD, of Memorial Sloan Kettering Cancer Center, New York, who presented the analysis at the 2017 ASCO-SITC (Society for Immunotherapy of Cancer) Clinical Immuno-Oncology Symposium.”

Outlook in HER2+ Breast Cancer Much Brighter Today Than 10 Years Ago, Expert Says

Excerpt:

“Over the last decade, the treatment landscape in HER2-positive breast cancer has changed dramatically, says Sara Hurvitz, MD.

” ‘I believe that a patient diagnosed today has a much greater chance of being alive 5 or 10 years from now—some of them may even be cured—and that compares very favorably with the outlook of 10 years ago when we just had 1 or 2 therapies and no evidence to support using HER2-targeted therapies after a patient’s disease grew,’ Hurvitz said.

“In an interview with Targeted Oncology, Hurvitz director of the Hematology/Oncology Breast Cancer Program and an associate professor in the Department of Medicine at the University of California, Los Angeles, discusses ongoing advances that continue to revolutionize the treatment of patients with HER2+ breast cancer.”

Expert Discusses State of Immunotherapy in Prostate Cancer

Excerpt:

“Advancements in immunotherapy in the field of prostate cancer have been slow ever since the FDA approval of sipuleucel-T (Provenge) several years ago.

” ‘It’s an exceptionally challenging area. After the success of sipuleucel-T, there have been combinatorial approaches using radiopharmaceuticals, such as radium-223, the checkpoint inhibitor ipilimumab (Yervoy), as well as some chemotherapy regimens,’ says Susan F. Slovin, MD, PhD.

“In an interview with OncLive at the 2017 Interdisciplinary Prostate Cancer Congress, Slovin, a medical oncologist at Memorial Sloan Kettering Cancer Center, offered her expert insight on the current state of immunotherapy in prostate cancer.”

Encouraging Results for Patients with Aggressive Brain Cancer

Excerpt:

“Being diagnosed with a malignant brain tumor is devastating news for patients and their loved ones. Whereas some types of tumor respond well to treatment, others such as glioblastomas – the most common and aggressive brain tumors – are known to recur and progress within short times from the diagnosis. Patients diagnosed with this type of cancer, and who undergo current standard treatment, have a median survival of 16 months.

Based on recent information on the mechanisms of chemotherapy, a team of researchers of the McGill University Health Centre (MUHC) developed a new clinical approach to increase the efficiency of treatment in glioblastomas that increased the median survival to 22 months – bringing much needed hope to those affected by this aggressive disease. The findings of this promising phase II clinical trial have been published in the International Journal of Radiology Oncology.”
