Australian researchers said Wednesday they developed a blood test for melanoma in its infancy, calling it a "world first" that could save many lives.
Scientists, from Edith Cowan University, said the new test could "Patients whose melanoma was detected at an early stage have a five-year survival rate between 90 and 99%" said senior researcher Pauline Zaenker in a statement. She added that survival rates dropped to less than 50% if the cancer spread in the body.
"That's what makes this blood test as exciting as a potential screening tool because it can detect melanoma in its
research, published in the journal Oncotarget on Wednesday, included an essay involving 105 melanoma patients and 104 healthy people.
The procedure was detected early Melanoma is present in 79% of cases, according to scientists.
Melanoma is currently detected with the aid of a visual examination by a physician, with areas of concern surgically cut and biopsied.
Zaenker says the new process involved the identification of autoantibodies. The body produces in response to cancer.
"We examined a total of 1627 different types of antibodies to identify a combination of 10 antibodies that best indicated the presence of melanoma in confirmed patients compared to healthy volunteers," she added. Sanchia Aranda, Executive Director of the Cancer Council Australia, said the test would be important for high-risk groups, who need regular inspections of their spots and moles, which can be difficult and time-consuming.
pick up other types of less lethal but more common skin cancers, such as squamous cells and basal cell carcinomas.
"People must be very aware of whether they have solar or U lesions" Scientists will conduct another three-year clinical trial to validate the results and hope to have a test that clinics can use.
One in three cancer diagnosed is skin cancer, according to the World Health Organization, with Australia having one of the highest rates of melanoma in the world
