CRC Research Update

SCREENING
Early-onset CRC incidence continues to rise in adults under 50
Analyzing SEER data from 2004-2023, researchers found 10,395 early-onset CRC cases in 2023, with incidence trends concentrated among adults aged 20-49 years, raising questions about screening strategies for those newly eligible under the 2021 USPSTF update. (Am J Prev Med)
SCREENING
Gut microbiome profiles improve detection of precancerous lesions in FIT screening
In a Norwegian study of 1,034 FIT-positive screening participants, combining microbial profiles with quantitative FIT values improved detection of premalignant lesions beyond optimizing the FIT value alone. (Nat Commun)
TREATMENT
Case report: POLE-mutated, dMMR/MSI colorectal cancer
(Am J Ther)
LIVING WITH CRC
Single-port versus multi-port robotic surgery for colorectal cancer
In a propensity score-matched analysis of 104 patients per group with stage I-III CRC, researchers compared single-port and multi-port robotic surgery. Single-port robotic surgery may reduce incision burden compared with multi-port robotic surgery. (Surg Endosc)

🔬 Under 50 Spotlight

Research relevant to early-onset and younger CRC patients

SCREENING
SEER data shows 10,395 early-onset CRC cases in 2023
The study examined whether CRC incidence trends were concentrated among adults newly eligible for screening after the USPSTF lowered the recommended starting age from 50 to 45 years in 2021. (Am J Prev Med)

🧬 Biomarker Spotlight

Research by genetic subtype — KRAS, BRAF, MSI-H, HER2, and more

TREATMENT
Case report: POLE mutation combined with dMMR/MSI
(Am J Ther)

Research continues to refine screening strategies and identify patients who may benefit most from targeted and immune-based therapies.
