Penn Medicine's Dr. Sara Cherry presents her 2017 Precision Medicine Accelerator Fund project.

Lesley Stahl examined the astronomical cost of cancer drugs in "60 Minutes." She found many doctors are pushing back against the costly drugs. Dr. David Agus, lead physician at USC Norris Westside Cancer Center, discusses the rising costs of cancer drugs.

New cancer treatment drugs have been added to the United Nations list of essential medicines, announced the World Health Organization on July 10. These cancer drugs don’t have to be injected. They can be swallowed. According to the WHO, the five new cancer therapies are the best in terms of survival rates to treat melanoma, lung, blood and prostate cancers. Nivolumab and Pembrolizumab, two new drugs to treat melanoma, a skin cancer largely considered incurable, delivered up to 50 percent survival rates. Essential Medicines List, published by the WHO, contains medications that are considered most effective and safe to meet the essential needs in a health system. The list is updated every two years and around 155 countries utilise it to draft their national drug policies. The first such list came out in 1977 with 212 medications. The WHO released its 21st list this time with 460 medications. Other updates to the list include new oral anticoagulants to prevent stroke, an alternative to warfarin treatment of deep vein thrombosis. The list focuses on additional infectious diseases prevalent in developing countries such as cholera, dengue, and Zika. The WHO insists that these life-saving medicines be made available and cost-effective so that everyone can access them.

Two drugs for cancer patients are in short supply and that shortage could delay when patients can get life saving treatments. The drugs, cisplatin and carboplatin, used to be as widely available as aspirin but now 70% to 90% of doctors in the country that treat cancer have reported difficulty getting the drugs for their patients.
