Synthesizing a Marine Sponge Compound that Fights Cancer

Halichondrins, natural products isolated from marine sponges, have demonstrated antitumor activity both in live mice and in human cancer cell cultures. Previously, the limited supply of halichondrins has made it difficult to develop drugs utilizing their antitumor activity. However, after 30 years of research, scientists have now been able to harvest the tumor-fighting capabilities of halichondrins by incorporating a synthesized version into a drug called E7130. When halichondrins were first dis...

Can Artificial Intelligence Diagnose Skin Lesions? With Philipp Tschandl, MD, PhD

​ Philipp Tschandl, MD, PhD, and colleagues found that current artificial intelligence (AI) algorithms that use "deep learning"—a type of machine learning that is based on artificial neural networks— outperform humans, even experts, in the classification of pigmented skin lesions . In this interview with i3 Health, Philipp Tschandl, member of the Vienna Dermatologic Imaging Research (ViDIR) Group of the Medical University of Vienna's Department of Dermatology, discusses the significance of the s...

AI Beats Human Experts in Classifying Skin Lesions

A new study reports that artificial intelligence (AI) in the form of machine-learning algorithms outperforms human experts in the diagnosis of pigmented skin lesions. This web-based study, which was published in The Lancet Oncology , included 511 human readers from 63 countries. Of these, 55.4% were board-certified dermatologists, 23.1% were dermatology residents, and 16.2% were general practitioners. The human readers were asked to diagnose dermatoscopic images that had been randomly selected i...

Metastatic Melanoma: Dabrafenib/Trametinib Improves Outcomes

Historically, patients with metastatic melanoma have a poor prognosis. However, due to the development of BRAF- and MEK-targeted therapies, patient outcomes have improved. To further characterize the outcomes associated with these treatments, researchers compiled and analyzed data from two clinical trials and found that in patients with unresectable or metastatic melanoma with a BRAF V600E or V600K mutation, dabrafenib plus trametinib had many long-term benefits in about one third of patients. D...

Lifetime Brain Metastasis Risk in Older Patients With Cancer

Older adults with lung, breast, and skin cancers have an increased risk of developing brain metastasis during their lifetime. But how big is this risk? In an effort to find out, researchers used data from the Surveillance, Epidemiology, and End Results (SEER) Program on patients with lung cancer, breast cancer, or melanoma diagnosed with a brain metastasis, either one identified during primary cancer staging workup, called a synchronous brain metastasis (SBM), or one detected later in life, call...
