Objective:

To evaluate a new blood test based on immune system responses for diagnosing testicular cancer.

Approach:

Key Findings:

• The GCT-iSIGN test identified testicular cancer with high accuracy, detecting most cases missed by standard laboratory markers.
• The test correctly identified 23 of 24 cases lacking elevations in conventional biomarkers.
• The assay maintained diagnostic performance across different disease stages.

Interpretation:

The new assay measures the host immune response rather than tumor-derived proteins.

Limitations:

• Prospective validation is required before clinical implementation.
• The second immunosignature panel could distinguish seminoma from nonseminoma tumors but was not sufficient as a standalone diagnostic test.

Conclusion:
