Biomarkers predicting immunotherapy effectiveness in metastatic clear cell renal cell carcinoma (mccRCC) are needed. This study identified differentially expressed immune-related genes that accurately classify patients benefiting from immune checkpoint inhibition (ICI) treatment.
Area of Science:
- Oncology
- Immunology
- Genetics
Background:
- Clear cell renal cell carcinoma (ccRCC) is the most prevalent kidney cancer.
- Despite advances in targeted therapies and immune checkpoint inhibition (ICI), cures for metastatic ccRCC (mccRCC) remain infrequent.
- Optimal utilization of novel therapeutic agents requires predictive biomarkers for treatment efficacy.
Purpose of the Study:
- To explore mRNA expression profiles of inflammation and immunity-related circulating genes in mccRCC.
- To identify potential biomarkers for predicting response to ICI-based treatments.
- To develop a classification model for patient stratification based on gene expression.
Main Methods:
- Utilized RT2 profiler PCR Array (human cancer inflammation and immunity crosstalk kit) to assess gene mRNA expression.
- Analyzed differential gene expression between patients with clinical benefit and those who progressed on treatment.
- Employed machine learning approaches for sample classification.
Main Results:
- Identified several differentially expressed mRNAs in mccRCC patients who responded to treatment versus those who progressed.
- Demonstrated that gene expression profiles can accurately classify patient response to ICI therapy.
- Achieved high accuracy and specificity in sample classification based on identified mRNA signatures.
Conclusions:
- Circulating immune and inflammation-related gene expression profiles hold promise as predictive biomarkers for ICI therapy in mccRCC.
- Gene expression analysis, coupled with machine learning, can effectively stratify mccRCC patients for immunotherapy.
- Further validation of these biomarkers could optimize treatment selection and improve outcomes for mccRCC patients.
