New Hearing on Crash That Killed Florida Oncologist

Three years ago, oncologist Charles Canaan Williams, Jr, a lung cancer specialist and a senior member of the Thoracic Oncology Program at Moffitt Cancer Center, Tampa, Florida, was killed when an orange Dodge Charger flew through a stoplight at 95 mph and slammed into his car. The driver of the car, Igbinosa Oghubor, was subsequently

FDA OKs First Targeted Therapy for Subset of Patients With NSCLC

The US Food and Drug Administration (FDA) today granted an accelerated approval for amivantamab (Rybrevant) as the first targeted treatment for patients with non–small cell lung cancers (NSCLC) harboring epidermal growth factor receptor (EGFR) exon 20 insertion mutations. The FDA also approved the Guardant360 CDx as a companion diagnostic for the new drug. “With today’s

COVID-19 and lung cancer have a common pathway, say researchers

The coronavirus disease 2019 (COVID-19) is a transmissible viral disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen responsible for the ongoing global pandemic. The virus was first detected in Wuhan, China, at the end of 2019 and to date has caused over 109 million infections worldwide. With over 2.4 million

Scientists identify a possible new treatment for diabetic retinopathy

About one in three diabetic patients develops diabetic retinopathy (DR), which can impair vision and lead to blindness. A new study in The American Journal of Pathology, published by Elsevier, provides clear evidence that high glucose increases the levels of enzymatic precursor — lysyl oxidase propeptide (LOX-PP) — that promotes cell death, which was verified

Combination therapies could help treat fatal lung cancers: Combining a new class of drug with two other compounds can significantly shrink lung tumors in mice and human cancer cells

Combining a new class of drug with two other compounds can significantly shrink lung tumours in mice and human cancer cells, finds a new study led by the Francis Crick Institute and The Institute of Cancer Research, London. The study, published in Science Translational Medicine, looked at G12C KRAS inhibitors. This new type of drug

Durvalumab combined with chemotherapy improves overall survival in patients with lung cancer: First-line treatment reduces mortality risk by 27%

Adding immunotherapy in the form of durvalumab to chemotherapy improves overall survival in patients with extensive-stage small cell lung cancer, according to research presented today at the IASLC 2019 World Conference on Lung Cancer hosted by the International Association for the Study of Lung Cancer (IASLC). The research was presented by Dr. Luis Paz-Ares, from

Certain metabolites linked to stem cell function in the intestine: Molecules called ketone bodies may improve stem cells’ ability to regenerate new intestinal tissue

MIT biologists have discovered an unexpected effect of a ketogenic, or fat-rich, diet: They showed that high levels of ketone bodies, molecules produced by the breakdown of fat, help the intestine to maintain a large pool of adult stem cells, which are crucial for keeping the intestinal lining healthy. The researchers also found that intestinal

Nicotine-free e-cigarettes can damage blood vessels: Single instance of vaping immediately leads to reduced vascular function

Smoking e-cigarettes, also called vaping, has been marketed as a safe alternative to tobacco cigarettes and is rising in popularity among non-smoking adolescents. However, a single e-cigarette can be harmful to the body’s blood vessels — even when the vapor is entirely nicotine-free — according to a new study by researchers in the Perelman School

Transfer of oncogene in colon cancer cells demonstrated

For years, doctors and scientists have known very little about why patients can receive drugs successfully for months, or even years, before developing a drug resistance. New University of Minnesota Medical School research proposes that there is a cellular as well as molecular cause to this phenomenon in colon cancer, with potential application to other

Special fibroblasts help pancreatic cancer cells evade immune detection

Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer-related deaths in the world. Mostly chemoresistant, PDAC so far has no effective treatment. Understanding the connective tissue, called stroma, that surrounds, nurtures, and even protects PDAC tumors, is key to developing effective therapeutics. “PDAC patients are diagnosed really late, so we don’t know they’re

Macrophages’ pathway to nurture PTEN-deficient glioblastoma

A common genetic deficiency empowers glioblastoma to broadcast a molecular message to the wrong type of immune cell, summoning macrophages that protect and nurture the brain tumor instead of attacking it, researchers at The University of Texas MD Anderson Cancer Center report in Cancer Cell. The team’s work in mouse models of glioblastoma that lack
