Study Identifies Five Different Types of Prostate Cancer
Cancer treatment is increasingly moving from one size fits all approach to a much more tailored experience.
The treatment of prostate cancer appears to have taken a big step in that direction with the discovery by a team of scientists in the UK that there are actually five different types of the disease.
It is one of the most common types of cancer in men, but the effectiveness of treatment has been inconsistent, with patients having a wide range of reactions. So researchers from the Cancer Research UK Cambridge Institute and Addenbrooke’s Hospital sought to see if various forms of prostate cancer had their own genetic signature. A total of 259 men were examined, with samples of healthy and cancerous prostate tissue taken for analysis. Scientists looked for abnormal chromosomes and measured the activity of 100 different genes linked to the development of prostate cancer.
Ultimately, five distinct types were found, each with their own genetic signature, and this method was more effective at predicting the most aggressive cancers compared to existing systems.
Next steps involve delving into each cancer type to see how they behave and respond to different treatments.

FDA Approves First Drug Made on 3-D Printer
The US Food and Drug Administration (FDA) has approved the world’s first drug created through 3-D printing technology. It’s a dissolvable pill called SPRITAL (levetiracetam) that will be used to treat epilepsy.
Epilepsy is a disorder of the brain that is defined by seizures–a person is diagnosed with the condition when they have two or more seizures. Anti-seizure medication is the most common treatment for epilepsy and it has been found to be effective in two out of three patients who take it as prescribed. But a study found that 71 percent of epilepsy patients reported forgetting, missing or skipping a dose of anti-seizure medication at some point. Almost half of these patients reported having a seizure after their missed dose.
The new drug, developed by Aprecia Pharmaceuticals, is designed to address this problem. The 3-D printing technology allows the drug to be layered and tightly packed into one pill, which has the ability to dissolve instantly with just one sip of liquid. That makes it much easier to take.
This approach also allows up to 1,000 mg of the medication to be loaded into a single dose, and the layering technology can control the dosage much more accurately and tailor it the specific needs of the individual.
The medication is expected to be available early next year.
