NCT ID NCT03249389

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looked at how calcium and vitamin markers change in 146 breast cancer patients receiving standard adjuvant chemotherapy. Researchers measured these markers before, during, and after treatment to understand metabolic effects. The goal was to see how often patients develop high calcium in urine and how vitamin balance shifts over the course of chemotherapy.
