Clinical Trial Summary

This phase I trial tests whether fluoxetine (prozac) works to modify the tumor immune cells before surgery in patients with colorectal cancer. Fluoxetine is a commonly used selective serotonin reuptake inhibitor (SSRI) prescribed for major depressive disorder and generalized anxiety. Giving fluoxetine may modify the immune cell composition in the tumor and its microenvironment and may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread in patients with colorectal cancer.


Clinical Trial Description

PRIMARY OBJECTIVE: I. To evaluate alterations in tumor immune cell composition and activity under SSRI treatment. OUTLINE: Patients receive fluoxetine orally (PO) once daily (QD) for 10 days prior to surgery. ;
