Objective:

To identify small RNA molecules that can serve as a 'barcode' for cancer types detectable in blood, enabling a new liquid biopsy approach without prior tumor sequencing.

Approach:

Key Findings:

• OncRNAs provide a digital signature that can distinguish between cancer types and subtypes.
• Circulating oncRNAs may be released by cancer cells, offering a tumor-naive strategy for detection.
• Changes in oncRNA levels correlate with treatment response and long-term survival in breast cancer patients.

Interpretation:

OncRNA-based assays could simplify post-treatment monitoring and improve early detection of persistent disease without relying on tumor mutations.

Limitations:

• The study is retrospective and requires prospective validation.
• The applicability of oncRNA detection in other cancer types beyond breast cancer remains to be explored.

Conclusion:

If validated, oncRNA assays could enhance laboratory options for monitoring cancer recurrence and improve risk stratification after therapy.
