“About 10 percent of lung cancers in the United States and as many as 40 percent in Asia are driven by mutations in the EGFR gene. EGFR targeted treatment advances over the previous decade now result in multiple options for controlling the disease in the body, but due to the reduced ability of many of these drugs to penetrate into the brain, treating of disease in the brain remains challenging. When brain metastases are seen at diagnosis before a patient has tried EGFR-targeted drugs, it has been an open question whether doctors should try drugs alone just in case they work in the brain or move directly to whole-brain radiotherapy or stereotactic radiosurgery (a tightly focused form of radiation) first, followed by targeted medicines. A study published in the Journal of Clinical Oncology looks back at 351 patients with EGFR mutant lung cancer and brain metastases treated at six institutions to offer compelling preliminary evidence as to the best sequence of these techniques: Radiation followed by targeted medicines resulted in the longest overall survival.”
“In a single-arm phase II study, cabozantinib demonstrated clinical activity in patients with advanced carcinoid and pancreatic neuroendocrine tumors (pNETs). Partial responses (PRs) were observed in 15% of each cohort treated with cabozantinib and stable disease was the best response in about two-thirds of patients.
“Median progression-free survival (PFS) exceeded 20 months in the pNET cohort and was >30 months in the carcinoid tumor cohort, said Jennifer A. Chan, MD, at the 2017 Gastrointestinal (GI) Cancers Symposium.”
“Bristol-Myers Squibb (BMS) and AstraZeneca have each announced separate delays in the development of PD-1 and CTLA-4 inhibitor combinations as first-line therapies for patients with advanced or metastatic non–small cell lung cancer (NSCLC), according to statements from each of the companies.
“In its statement, BMS noted that it would not be pursuing an accelerated approval for the combination of nivolumab (Opdivo) and ipilimumab (Yervoy) as a frontline therapy for NSCLC. Instead, the company plans to delay the submission of data to the FDA until findings from a phase III study are available, most likely from the phase III CheckMate-227 trial.”
“Giving men with suspected prostate cancer an MRI scan could improve diagnosis and save those who do not have aggressive cancers from having an unnecessary biopsy, according to a study published in The Lancet.
“The study estimates that adding the extra test could help one in four (27%) men avoid an unnecessary biopsy and reduce the number of men who are over-diagnosed – diagnosed with a cancer that does not go on to cause any harm during their lifetime – by 5%.”
“Bristol-Myers Squibb Co on Thursday said it has decided not to seek accelerated U.S. approval for a combination of its two immunotherapy drugs as an initial treatment for lung cancer.
“Shares of Bristol, which closed at $55.49 on the New York Stock Exchange, were down 6.2 percent at $52.08 after hours.
“The pharmaceutical company cited ‘a review of data available at this time’ for the decision to hold off on filing for Food and Drug Administration approval of the combination of its cancer drugs Opdivo and Yervoy.”

“A national study by researchers at UC Davis Comprehensive Cancer Center has found that a significant number of lung cancer patients are not receiving treatment. Based on data between 1998 and 2012 from the National Cancer Database, 21 percent of patients (190,539) with non-small cell lung cancer (NSCLC) received no specific cancer treatment, such as chemotherapy, radiotherapy or surgery. Many of the untreated patients were women, elderly, minorities, low income and uninsured.”
“New research shows that taking molecular variables into account will improve the prognostic classification of the lethal brain cancer called glioblastoma (GBM).
“The study was led by researchers at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James).
“Published in the journal JAMA Oncology, the study found that adding significant molecular biomarkers to the existing GBM classification system improves the prognostic classification of GBM patients who have been treated with radiation and the drug temozolomide.”
“A team of Dana-Farber scientists has released new research with an important message about precision medicine: Sequencing the genes of brain tumors in kids could point to treatments that target their genetic abnormalities and therefore have the best chance of being effective. At least one of those drugs is already on the market, Novartis’ Tafinlar (dabrafenib), approved by the FDA to treat other types of cancer but still readily available to pediatric oncologists who may want to try it in their patients.”
“Men with localized prostate cancer face good odds: Their relative five-year survival rate is nearly 100 percent. However, men with metastatic disease — prostate cancer that has spread to another organ like the lungs — have a relative five-year survival rate of only 29 percent.
“Currently, the mainstay treatment for metastatic prostate cancer is hormone therapy, which uses drugs to lower the levels of male sex hormones like testosterone in the body to slow the growth of prostate cancer. Two of the latest hormonal agents, abiraterone acetate and enzalutamide, have shown some improvements in overall survival. Unfortunately, hormone therapy isn’t a cure and most patients become resistant to the drugs.”
