MRD evidence
What the studies show
Landmark papers an MRD reader should know, including trials that did not meet their aim. Numbers below are taken from the abstracts. Assay names are labels, not a ranking. The full list remains on Research. Multi-cancer early detection is on MCED.
Level 1
A prospective trial in which the ctDNA or MRD result assigns, withholds, or changes treatment. Randomized and single-arm adaptive trials both qualify. Positive and negative trials are listed.
Level 2
A large prospective observational cohort, or a correlative analysis from a phase 3 trial or other large study. The test informs prognosis or describes a treatment association. It does not assign therapy.
Level 3
A smaller cohort, a single-center series, a feasibility study, or an analytical validation. Useful for methods and early signals, not for changing practice on its own.

Liquid Biopsy for Minimal Residual Disease Detection in Head and Neck Squamous Cell Carcinoma (LIONESS): A personalized cell-free tumor DNA analysis for patients with HNSCC.
Flach, Susanne · Abstract 6017 · LIONESS · 35 patients, 236 longitudinal plasma samples; prospective observational; median follow-up 9.5 months at this report
RaDaR (personalized panels targeting a median of 48 somatic variants, range 20-60)
Baseline (pre-surgery) ctDNA detection was 94.28%. Recurrence occurred in 8/11 (72.7%) patients who were ctDNA-positive during follow-up vs 0/24 who were ctDNA-negative (P=7e-7). In all 8 clinical recurrences, ctDNA was detected first, with lead times of 56 to 265 days. Post-surgery ctDNA was detected at variant allele fractions as low as 0.0005%.
