According to Mr. Chi Hwan Lee, head of the research team, the new patch with microscopic needles allows the delivery of drugs to treat skin cancer. This type of patch is painless and dissolves automatically after the drug is introduced into the patient’s body.
Recent advances in topical chemotherapy at the mass melanoma has provided more effective post-surgical treatment options than standard chemotherapy Furthermore, they reduce toxicity and side effects. However, these therapies often use small needles and can be particularly painful, for example in the treatment of cupping-induced ocular melanoma The fascia is very sensitive.
The treatment patch is made up of a soft, water-soluble film that dissolves quickly after specially designed silicon nanofibers are inserted into the skin. These nano needles are harmless with living tissue and after the microscopic needles slowly release the drug through the skin, they will be absorbed by the body. The needle tip is designed with a large enough drug loading capacity to continuously deliver the drug before it dissolves causes pain and is minimally invasive. Their capacity is equivalent to that of larger needles currently used for topical chemotherapy.
According to the American Cancer Society (ACS), about 100,350 cases of melanoma will be diagnosed in the US by the end of 2020. Melanoma accounts for a higher mortality rate than any other type of skin cancer. ACS predicts there will be 6,850 deaths from melanoma this year.
Removing the tumor with surgical excision is the preferred treatment for skin cancer. However, melanoma can grow and recur frequently, forcing the patient to have to repeat regular chemotherapy and radiotherapy sessions. Because these therapies can be difficult for patients and often cause toxicity and other side effects. However, topical chemotherapy is considered a more tolerable method and can be equally effective.
