A 72-year-old man developed aggressive skin cancer on his left thumb 30 years after a burn injury, illustrating the decades-long latency of Marjolin ulcer. This rare but deadly cancer behaves far more aggressively than common skin cancers, underscoring the critical need for lifelong monitoring of old scars and immediate biopsy of any suspicious changes.
A new gene therapy has been used to successfully treat a deadly childhood liver disease using mice that model this disease by researchers at UCL and Great Ormond Street Hospital.
For some people, cancer immunotherapies are life-changing. These treatments can turn the body’s own immune system against a tumor, either eliminating it or shrinking it enough to make surgery possible. But these therapies don’t work for everyone, can gradually stop working or can come with a host of side effects, including severe inflammation. A new experimental therapy aims to change that. Scripps Research scientists are testing SAR’877, a bispecific molecule designed to restore immune cells’ ability to fight cancer.
New University of Calgary research reveals that eliminating a single gene improves immunotherapy for colorectal cancer — a fundamental breakthrough.
