Doctors Define "Safe and Effective" Margins For "One and Done" Skin Removal Around Suspicious Moles
NYU Langone Health

By carefully tracing a line of at least 2 millimeters outside of and around the edges of a mole that is suspected of being a cancer, doctors can remove all of its cells and avert the need for a second surgery.

Tumor-infiltrating B Lymphocytes Promote Melanoma Progression and Resistance to Therapy
Wistar Institute

In a multi-institutional collaborative study, scientists at The Wistar Institute and the Medical University of Vienna, Austria, have identified the role of tumor-infiltrating or tumor-associated B-cells (“TABs”) in melanoma progression and resistance to targeted therapy.

How to Remove a Tick and Prevent Future Bites
American Academy of Dermatology

As tick populations grow and spread across the country, their prevalence is increasing the public’s risk for some troubling diseases. Of these diseases, say dermatologists from the American Academy of Dermatology, Lyme disease, Rocky Mountain spotted fever, Powassan virus and alpha-gal syndrome—a mysterious red meat allergy—are among the most serious.

Treatment-Resistant Melanoma May Be Vulnerable to a Drug Holiday, UCLA Study Finds
University of California, Los Angeles (UCLA), Health Sciences

A UCLA study has uncovered the mechanisms by which treatment-resistant melanoma become vulnerable to cessation of a class of drugs called MAP kinase (MAPK)-targeted inhibitors. By identifying these mechanisms, the scientists discovered that therapeutic benefits for patients could derive from a one-two punch of a drug holiday of MAPK inhibitors followed by a class of drugs called DNA repair inhibitors.

Double Agents: Vessels That Help Cancers Spread Can Also Boost Immune Therapies
University of Chicago Medical Center

Lymphatic vessels, often blamed for enabling cancer cells to spread from a primary location to many other sites, have a flip side. A team of researchers found that in patients being treated with checkpoint inhibitors, lymphangiogenesis boosts the immune system’s primary anti-cancer tool, T cells, enabling them to infiltrate tumors and kill cancer cells.

Alternative Immunotherapy Drug More Effective than Current Standard of Care in Treating Advanced Melanoma after Surgical Removal of Disease
NYU Langone Health

The immunotherapy drug nivolumab is safer and more effective than ipilimumab—the current standard of care—in treating patients with resected stage III and stage IV melanoma.

Study Unlocks How Changes in Gene Activity Early During Therapy Can Establish the Roots of Drug-Resistant Melanoma
University of California, Los Angeles (UCLA), Health Sciences

A UCLA-led study of changes in gene activity in BRAF-mutated melanoma suggests these epigenomic alterations are not random but can explain how tumors are already developing resistance as they shrink in response to treatment with a powerful class of drugs called MAP kinase (MAPK)-targeted inhibitors.

Cancer Immunotherapy May Get a Boost by Disabling Specific T Cells
Columbia University Irving Medical Center

Cancer immunotherapy drugs only work for a minority of patients, but a generic drug now used to increase blood flow may be able to improve those odds, a study by Columbia University Medical Center (CUMC) researchers suggests.

Human Skin Cells Transformed Directly Into Motor Neurons
Washington University in St. Louis

In new research, scientists at Washington University School of Medicine in St. Louis have converted skin cells from healthy adults directly into motor neurons without going through a stem cell state. The technique makes it possible to study motor neurons of the human central nervous system in the lab. Unlike commonly studied mouse motor neurons, human motor neurons growing in the lab would be a new tool since researchers can’t take samples of these neurons from living people but can easily take skin samples.

Severity of Psoriasis Linked to Increased Risk of Death
Perelman School of Medicine at the University of Pennsylvania

The more the surface area of the body is covered by psoriasis, the greater the risk of death for the patient suffering from the condition, according to a new analysis by researchers in the Perelman School of Medicine at the University of Pennsylvania. Patients with psoriasis on 10 percent or more of their body are at almost double the risk of death.
