A new hope for melanoma detection

A team of researchers has discovered a new formula to detect circulating tumor cells of melanoma in the blood that can serve to prevent its spread in other organs.

Melanoma, one of the most deadly types of skin cancer, is a disease diagnosed every year to about 160,000 people globally and causes the death of 57,000, according to the World Health Organization (WHO).

The great difficulty facing this type of cancer, unlike others, is the speed with which it originates, as well as its complicated prevention and detection in early stages. Therefore, according to the American Cancer Society, it is more likely to spread to other parts of the body if it is not treated in time.

In this sense, a new discovery can draw the path to a better treatment of the disease. The Melanoma Research Group of Edith Cowan University (Australia), together with Harvard Medical School, has discovered a new technique capable of detecting circulating tumor cells (CTC) that could be used to detect and treat melanoma cancer.

Combination of multiple approaches and essays
The study, published in the British Journal of Cancer, was based on the fact that the great heterogeneity of these melanoma tumor cells hindered their detection and treatment, so a new formula had to be found to evaluate them through blood samples.

«Melanoma CTCs are hidden among thousands of other cells and matter in the blood. Within a milliliter of blood there are less than 10 cancer cells between one billion red blood cells and one million white blood cells, ”explained one of the main authors of the study, Professor Elin Gray, in statements collected by Europa Press.

That is why this new method can be so hopeful. The main idea was to understand that they cannot analyze and search for these cells with a single focus. To do this, the team of experts experimented with a multifaceted approach combining three trials and raising the detection rates to 72 percent.

Melanoma is a type of cancer that originates in melanocytes and spreads throughout the body, generating metastases when tumor cells “detach from the primary tumor and travel through the blood to form secondary tumors in other organs,” he adds. expert

This new detection opportunity can be key to its treatment and, above all, to prevent its spread. Undoubtedly, a breakthrough that could reverse melanoma rates worldwide.
