Long-term IMPACT data find improved survival when targeted therapies matched to tumor-specific gene mutations
Matching targeted therapies to tumor-specific gene mutations across tumor types improved progression-free survival (PFS) and overall survival (OS) in patients with advanced disease relative to those receiving non-matched treatment (NMT), according to research from The University of Texas MD Anderson Cancer Center.
Blood test shows potential for early detection of lung cancer
A test that analyzes free-floating DNA in the blood may be able to detect early-stage lung cancer, a preliminary report from the ongoing Circulating Cell-Free Genome Atlas (CCGA) study suggests.
Increase in lifestyle-related cancers over past decade spotlights need for prevention
Lifestyle-related cancers, such as lung, colorectal, and skin cancers, have increased globally over the past decade, according to the most comprehensive analysis of cancer-related health outcomes and patterns ever conducted.
Earth's first giant predators produced killer babies
A new fossil study, led by Jianni Liu from the Northwest University in China, shows young radiodontan arthropods could be voracious predators too.
Study of acute myeloid leukemia patients shows protein inhibitor drug safe and effective with durable remissions
Ivosidenib, an experimental drug that inhibits a protein often mutated in several cancers has been shown to be safe, resulting in durable remissions, in a study of acute myeloid leukemia (AML) with relapsed or refractory disease.
ASCO18: Positive results for phase 1 trial of ivosidenib against AML
AML patients treated with the IDH1 inhibitor ivosidenib show an overall response rate of 41.9 percent, with median progression free survival of 8.2 months.
Study updates global burden of cancer
Population aging and growth largely fueled an increase in cancer cases between 2006 and 2016, and large disparities continue to exist between countries in cancer incidence, deaths and the disease's associated disability.

#509 Anisogamy: The Beginning of Male and Female
This week we discuss how the sperm and egg came to be, and how a difference of reproductive interest has led to sexual conflict in bed bugs. We'll be speaking with Dr. Geoff Parker, an evolutionary biologist credited with developing a theory to explain the evolution of two sexes, about anisogamy, sexual reproduction through the fusion of two different gametes: the egg and the sperm. Then we'll speak with Dr. Roberto Pereira, research scientist in urban entomology at the University of Florida, about traumatic insemination in bed bugs.
