Enhanced Cancer Immunotherapy by Microneedle Patch-Assisted Delivery of Anti-PD1 Antibody.
Biomedical engineering researchers have developed a technique that uses a patch embedded with microneedles to deliver cancer immunotherapy treatment directly to the site of melanoma skin cancer. In animal studies, the technique more effectively targeted melanoma than other immunotherapy treatments.
More than 67,000 people in the US were diagnosed with melanoma in 2012 alone – the most recent year for which data are available. If caught early, melanoma patients have a 5yr survival rate of more than 98%. That number dips to 16.6% if the cancer has metastasized before diagnosis and treatment.
