Alterations of Nutrient Elements in Hepatocellular Carcinoma Patients Treated with Atezolizumab-Bevacizumab.

Currently, the combination of atezolizumab and bevacizumab (Atez/Bev) is recommended as the first-line therapy for patients with advanced hepatocellular carcinoma (HCC). However, there is a lack of research on the levels of nutrient elements in advanced HCC patients receiving Atez/Bev treatment. In this study, data from 35 patients with advanced HCC and 37 healthy individuals of similar age and sex were included. The levels of alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase were significantly increased in patients with HCC. These levels returned to the reference range after three rounds of Atez/Bev treatment. Additionally, the levels of blood urea nitrogen and creatinine (Cr) increased after Atez/Bev treatment. In HCC patients, the levels of calcium (Ca), iron (Fe), and copper (Cu) were significantly higher, while the levels of sodium (Na), magnesium (Mg), and zinc (Zn) were significantly lower compared to healthy individuals. These changes were reversed after Atez/Bev treatment. In conclusion, our findings indicate that treatment with Atez/Bev influences the levels of Ca, Fe, Cu, Na, Mg, and Zn in patients with HCC. The alterations in these elements caused by Atez/Bev treatment require mechanistic research in the future.
