A new study from Karolinska University Hospital and Karolinska Institutet, published in the journal Oncology, reports that a patient with advanced, treatment-resistant lung cancer became tumor-free after treatment with the selenium compound selenite. The case was part of a clinical trial investigating the effects of selenite in patients with solid tumors.
The patient, who had previously exhausted standard treatment options, received selenite therapy and showed a complete response, with no detectable tumors on follow-up imaging. The researchers emphasize that this is a single case and that further studies are needed to confirm the efficacy and safety of selenite in larger patient groups.
Selenite is a form of the essential trace element selenium, which has been studied for its potential anti-cancer properties. The Karolinska team is continuing to investigate the mechanisms behind the observed effect and plans to expand the research to include more patients.
Experts caution that while the result is promising, it is not yet a proven treatment, and patients should not seek selenite supplements without medical supervision, as high doses can be toxic.
