NCT06680778

Brief Summary

The goal of this single center prospective observational study is to determine the effect of chemotherapy on (the change in) vital parameters. The main question it aims to answer are: Can changes in vital parameters be measured by using a Fitbit in patients with cancer while undergoing chemotherapy. Participants will be asked to wear a Fitbit for the first two cycles of chemotherapy to evaluate the changes in vital parameters.
