Uit twee gerandomiseerde studies, de fase II studie PEGASUS en de fase III studie DYNAMIC, blijkt dat een negatief resultaat op aanwezigheid van kankercellen bij patiënten met darmkanker stadium III verkregen via een ctDNA test = circulerend tumor-DNA bloedtest geen verschil maakt met standaard chemotherapie als behandeling.
Uit de fase III studie DYNAMIC blijkt dat na een mediane follow-up van 47 maanden de 3-jaars recidiefvrije overleving als resultaat te geven 85,3% in de ctDNA-geleide groep versus 88,1% in de standaard chemogroep (absoluut verschil -2,8%; 95%-betrouwbaarheidsinterval -8,0-2,3), waarmee de ondergrens van -7,5% werd overschreden.
Uit de fase II studie PEGASUS werd de aanwezigheid versus afwezigheid van ctDNA geassocieerd met een slechtere ziektevrije overleving op 3 jaars meting: respectievelijk 58,4% versus 82,8%; hazard ratio 2,70; p=0,0036) en algehele overleving (79,7% versus 93,8%; HR 3,11; p=0,0383) bij een mediane follow-up van 42 maanden. Waarbij aangetekend dat in deze analyse slechts 100 patiënten die een ctDNA hadden gekregen versus slechts 34 patiënten die geen ctDNA-test hadden gehad. Bovendien en dat lijkt cruciaal bij een negatieve uitslag van de ctDNA test, dus dat er geen kankercellen werden gevonden na de operatie leidde tot een vermindering van de chemotherapie, zowel in intensiteit als in tijd. Terwijl bij darmkanker stadium III al uitzaaiingen zijn gevonden in de lymfklieren in de nabijheid van de primaire tumor. En wellicht de operatie niet alle kankercellen heeft kunnen weghalen of waren er al kankercellen hoewel niet aantoonbaar elders in andere lymfklieren en/of organen. Zie uitleg daarover verder in dit artikel.

Waarom deze resultaten kritisch moeten worden bekeken blijkt uit deze korte uitleg:
In de fase III studie DYNAMIC veranderden de oncologen in de klinische parktijk van de ziekenhuizen het geselecteerde chemotherapie behandelingsschema na de operatie voorafgaand aan indeling in de twee groepen naar ctDNA geïnformeerd of standaardbeleid.
Bij ctDNA-geïnformeerd beleid leidde een ctDNA-negatief resultaat 5-6 weken na de operatie met de SaferSeqS-gerichte CRC-paneltest tot een geleidelijk afbouwend behandelingsplan van:
- 6 maanden monotherapie met fluoropyrimidine naar geen chemotherapie of 3 maanden fluoropyrimidine;
- van 3 maanden oxaliplatine plus fluoropyrimidine naar 3-6 maanden fluoropyrimidine;
- of van 6 maanden oxaliplatine plus fluoropyrimidine naar 3 maanden oxaliplatine plus fluoropyrimidine of 6 maanden fluoropyrimidine).
Hieronder achtereenvolgens het abstract van de fase III studie DYNAMIC. Daaronder het abstract van de fase II studie PEGASUS.

Background
Prognostic impact of circulating tumor DNA (ctDNA) positivity on colon cancer disease relapse after radical resection and adjuvant chemotherapy has been previously demonstrated. Here we present the final analysis on the primary endpoint of the PEGASUS trial, designed to investigate the feasibility of using liquid biopsy (LB) to guide the post-surgical and post-adjuvant clinical management of Stage III and T4N0 Stage II colon cancer patients (pts).
Methods
LB was performed using Guardant Reveal assay (v L1.2). In the post-surgical phase, LB+ pts received 3 months of CAPOX and LB- pts 6 months of CAPE. To mitigate the risk of false negatives, after one cycle of CAPE a second LB was performed and if positive the treatment was escalated to CAPOX. At the end of the adjuvant treatment, LB was repeated: CAPOX-treated patients were switched to FOLFIRI if LB+ or de-escalated to CAPE if LB-; CAPE-treated patients received CAPOX if LB+ or standard follow-up if LB-. Primary objective was feasibility of the LB-based strategy, defined as the rate of pts free of disease at 2 years among those with two consecutive post-surgical LB– results. With one-sided α=0.05 and 80% power, <14 relapses among 134 LB- pts were required to exclude H0=85% in favor of H1=92%. A matched comparison with TOSCA Trial pts was planned as a secondary endpoint.
Results
From July 2020 to July 2022, 135 pts (100 LB-, 35 LB+) were included from 11 clinical cancer centers in Italy and Spain. At a median follow-up of 33.5 months, 12 relapses occurred among LB– pts, yielding a 2-year NED rate of 88% (90% CI, 81–93). The predefined threshold was not met, but the point estimate exceeded 85% and the confidence interval extended beyond 92%, indicating promise but statistical uncertainty. Within the 35 LB+ pts, 13 (37%) relapses were observed. 2-years time-to-relapse rate was 87.6% in LB- and 61.5% in LB+ (HR 3.22, 95% CI 1.20–7.96, p=0.0013).
Conclusions
PEGASUS showed the operational feasibility of ctDNA-guided treatment in stage III and high-risk stage II resected colon cancer. This approach has the potential to reduce unnecessary toxicity by tailoring adjuvant therapy to molecular risk. A historical comparative analysis with pts from the TOSCA trial is ongoing as per-protocol key secondary endpoint.

Background
Serial monitoring of ctDNA-based molecular residual disease after radical cystectomy in patients (pts) with high-risk muscle-invasive bladder cancer shows promise in differentiating pts who need adjuvant therapy from those who can safely avoid treatment. We report the primary analysis of the global, randomised, double-blind, phase 3 IMvigor011 trial (NCT04660344) studying ctDNA-guided atezolizumab (atezo) vs placebo in this setting.
Methods
Pts with muscle-invasive bladder cancer and no radiographic evidence of disease enrolled in surveillance within 6–24 weeks of cystectomy and underwent serial ctDNA monitoring for up to 1 year after surgery. Eligible pts who tested ctDNA+ were randomised 2:1 to atezo 1680 mg or placebo every 4 weeks for 12 cycles or up to 1 year. The primary endpoint was investigator-assessed disease-free survival (DFS). Overall survival (OS) was a secondary endpoint with alpha control. Pts who persistently tested ctDNA− received no treatment.
Results
Overall, 761 pts were enrolled in surveillance. 250 eligible pts who tested ctDNA+ were randomised (atezo, n=167; placebo, n=83). At a median follow-up of 16.1 months, pts in the atezo arm had statistically significant improvements in DFS (HR, 0.64; 95% CI: 0.47, 0.87;

Conclusions
ctDNA-guided adjuvant atezo showed statistically significant and clinically meaningful DFS and OS improvements vs placebo. The atezo safety profile was tolerable, with no new findings. Pts who persistently tested ctDNA− had low risk of recurrence.
