Researchers use radioactive iodine to treat skin tumors, lung and colon

Spanish researchers have developed a new gene therapy treatment for different types of cancer such as skin, lung and colon cancer, using radioactive iodine, usually used to fight cancer cells in the thyroid.

Researchers at the Higher Council for Scientific Research (CSIC, the Spanish acronym) and the La Paz Hospital in Madrid, conducted a study using mice with a gene called NIS, present in thyroid cells. The radioactive iodine treatment of thyroid cancer is effective thanks to this gene, which carries the iodine inside the cell.

To insert the gene into a tissue that was not his, the scientists used a vector in this case a virus (adenovirus) genetically modified to carry the DNA to cancer cells.

According to Garcilaso Riesco-Eizaguirre researcher, Institute of Biomedical Research of the Hospital La Paz, this advance opens the possibility for future treatment of melanoma with radioactive iodine.

"Through gene therapy, we can use the NIS exogenously in other types of cancer and extend the medical use of radioactive iodine," he said.
