The use of antibiotics is often considered among the most important advances in the treatment of human disease. Unfortunately, though, bacteria are finding ways to make a comeback. According to the Centers for Disease Control, more than two million people come down with antibiotic-resistant infections annually, and at least 23,000 die because their treatment can't stop the infection.

Adding bevacizumab (Avastin) to standard chemotherapy and radiation treatment does not improve survival for patients newly diagnosed with the often deadly brain cancer glioblastoma, researchers report in the Feb. 20 issue of the New England Journal of Medicine.

In a study published in Nature Communications, researchers at Karolinska Institutet and Uppsala University in Sweden present a new drug candidate, which selectively kills dormant cells within a cancer tumour through starvation. These tumour cells, which are found in less oxygenated parts of solid tumours, are resistant to conventional treatments.

Over the past decade, a great clinical focus has been directed at developing new and innovative therapies for advanced non-small cell lung cancer (NSCLC). An analysis of clinical trials evaluating these therapies demonstrates that the cumulative success rate for new agents for advanced NSCLC is lower than the industry-estimated rate. However, biomarker- and receptor-targeted therapies were found to substantially increase clinical trial success.

University of Adelaide research has shown for the first time that grape seed can aid the effectiveness of chemotherapy in killing colon cancer cells as well as reducing the chemotherapy's side effects. Published in the journal PLOS ONE, the researchers say that combining grape seed extracts with chemotherapy has potential as a new approach for bowel cancer treatment - to both reduce intestinal damage commonly caused by cancer chemotherapy and to enhance its effect.

A group of researchers at the Institute for Research in Immunology and Cancer (IRIC) of Université de Montréal discovered a promising new approach to treating leukemia by disarming a gene that is responsible for tumor progression. That gene, known as Brg1 is a key regulator of leukemia stem cells that are the root cause of the disease, resistance to treatment and relapse.

The development of drugs to treat acute stroke or aid in stroke recovery is a multibillion-dollar endeavor that only rarely pays off in the form of government-approved pharmaceuticals. Drug companies spend years testing safety and dosage in the clinic, only to find in Phase III clinical efficacy trials that target compounds have little to no benefit.
