Summary of the Proposed Research:

Magnesium is essential for activating immune cells in our bodies and magnesium deficiency, a condition in which the amount of magnesium in the blood is lower than normal, is shown to be associated with a worse response to cancer immunotherapy, a type of treatment that uses immune system in our body to fight cancer. Immunotherapy has been used for the treatment for cancer of the bladder, ureter, and renal pelvis that has spread to other parts of the body. However, the association between magnesium levels in the blood and treatment outcomes for patients with cancer of the bladder, ureter, and renal pelvis treated with immunotherapy remains unclear. Using the data from the clinical trials, it is possible to evaluate the association between magnesium levels in the blood and treatment outcome of patients with advanced cancer of the bladder, ureter, and renal pelvis treated with atezolizumab, a cancer immunotherapy that enhances the immune response against cancer. Given the possibility that magnesium deficiency is treatable and common in chemotherapy-treated patients with cancer of the bladder, ureter, and renal pelvis, the results of this study may improve their management.
