The Role of the Tumor Molecular Profile (CMS), UGT1A1 Genotype and Beta-glucuronidase Activity of the Intestinal Microbiota for Treatment Efficiency, Toxicity, Survival and Quality of Life in Patients With Metastatic or Unresectable Colorectal Cancer During Irinotecan-based Systemic Treatment

Summary

Irinotecan-based systemic therapy is a treatment option for metastatic or unresectable colorectal cancer. However, this therapy has two major disadvantages, namely, an unpredictable response to the treatment and severe side effects, for instance diarrhea or a low white blood cell count (neutropenia). Therefore, the OPTIMA study was developed to find out if biomarkers, such as the molecular profile of the tumor, the UGT1A1 genotype and activity of the bacterial enzyme β-glucuronidase, can predict response and side effects during irinotecan treatment. By looking at these biomarkers, treatments could be more personalized, resulting into enhanced therapy efficiency, increased optimal survival and a better quality of life.
