mt-sDNA is supior tool for CRC screening

Yes, multitarget stool DNA (mt-sDNA) is considered a superior tool for colorectal cancer (CRC) screening, especially for younger adults under 50, based on the findings of the study outlined in the context. Here's why mt-sDNA is superior:

1. **Higher Follow-Up Colonoscopy Adherence**:

• Among individuals aged 45–49 with a positive stool-based test, follow-up colonoscopy (FU-CY) adherence within 12 months was significantly higher for mt-sDNA users (85.0%) compared to fecal immunochemical test/occult blood test (FIT/FOBT) users (35.2%). This indicates that mt-sDNA testing leads to better compliance with recommended follow-up procedures.

2. **Faster Follow-Up Timeliness**:

• The mean time to colonoscopy after a positive test was shorter for mt-sDNA users (74.5 days) compared to FIT/FOBT users (90.8 days). This faster follow-up is crucial for timely detection and prevention of colorectal cancer progression.

3. **Benchmark Achievement**:

• mt-sDNA users exceeded the US Multi-Society Task Force’s benchmark of 80% adherence for post-screening colonoscopy completion, demonstrating its effectiveness in ensuring adherence to screening protocols.

4. **Early Follow-Up Rates**:

• Within the first 90 days after testing, a significantly higher percentage of mt-sDNA users (62.9%) completed their follow-up colonoscopy compared to FIT/FOBT users (22.8%). Early follow-up is critical for detecting early-onset colorectal cancer and improving outcomes.

5. **Target Population**:

• The study specifically focused on adults aged 45–49, a group increasingly recognized for its risk of early-onset colorectal cancer. mt-sDNA testing proved to be a more effective screening tool for this younger population.

6. **Study Scale and Robustness**:

• The findings are backed by robust data from the Komodo Research Data (KRD) database and Exact Sciences Laboratory (ESL), which together cover over 165 million lives. This large claims-based dataset adds credibility to the study's conclusions.

In summary, mt-sDNA testing outperforms FIT/FOBT in terms of follow-up adherence, timeliness, and overall effectiveness as a screening tool for colorectal cancer prevention in younger adults. Its ability to ensure timely and consistent follow-up after a positive test makes it a superior choice for CRC screening, particularly for individuals under 50.
