Immuuntherapie vooraf aan operatie bij patiënten met darmkanker met een zogeheten mismatch repair deficiëntie geeft een zeer goed effect want alle 111 deelnemende patiënten aan de Niche-2 studie bleven minimaal 5 jaar kankervrij zonder recidief.

De resultaten uit het abstract vertaald:

  • Van 4 juli 2017 tot 18 juli 2022 werden 123 patiënten gescreend; van hen werden 115 patiënten behandeld en 111 patiënten opgenomen in de 'per-protocol'-populatie. Op de peildatum voor data-analyse (19 juni 2026) bedroeg de mediane postoperatieve follow-upduur 58,7 maanden (interkwartielafstand 49,0–72,9).
  • De ziektevrije overleving na 3 jaar was 100% (97,5%-betrouwbaarheidsinterval 100–100). Na een mediane follow-upduur van 60,4 maanden (IQR 50,6–74,1), gerekend vanaf het moment van inclusie in de studie, bedroeg de algehele overleving na 5 jaar 100% (95%-BI 100–100).
  • Bij patiënten van wie plasmamonsters beschikbaar waren, werd bij aanvang van de studie bij 99 van de 108 patiënten (92%) circulerend tumor-DNA (ctDNA) aangetroffen.
  • Na de eerste behandelcyclus (in week 2) was bij 44 van de 98 patiënten (45%) geen ctDNA meer detecteerbaar ('klaring'), en na de tweede cyclus (vóór de operatie) gold dit voor 80 van de 97 patiënten (82%).
  • Bij patiënten met een pathologische 'bijna volledige' respons of een 'volledige' respons werd vóór de operatie bij respectievelijk 19 van de 27 patiënten (70%) en 60 van de 65 patiënten (92%) ctDNA-klaring waargenomen.
  • Bij onderzoek naar minimale restziekte na de operatie bleken alle patiënten ctDNA-negatief te zijn.

Vijf jaar na immuuntherapie nog geen terugkeer van darmkanker

22 okt. 2026 00:30

Nieuwe resultaten NICHE-2 studie bevestigen succes van korte behandeling met immuuntherapie voor operatie

Patiënten met een specifieke vorm van darmkanker die vóór hun operatie een korte behandeling met immuuntherapie kregen, zijn ook jaren later nog vrij van kanker. Bij geen van de 111 patiënten die deelnamen aan de NICHE-2-studie is de kanker teruggekomen en alle patiënten zijn na vijf jaar nog in leven.>>>>>>>lees verder

Summary

Background

Neoadjuvant immune checkpoint blockade induces high pathological response rates in patients with locally advanced mismatch repair-deficient (dMMR) colon cancer, yet long-term survival outcomes have not been established. Previously, we reported safety (a primary endpoint) and pathological response (a secondary endpoint) data from the NICHE-2 trial. Here, we report the primary efficacy endpoint of 3-year disease-free survival and the exploratory endpoint of 5-year overall survival.

Methods

In this single-arm, multicentre, phase 2, NICHE-2 trial, patients with previously untreated, clinical stage 2 or 3, resectable dMMR colon cancer received a single dose of intravenous ipilimumab (1 mg per kg) on day 1, and two doses of intravenous nivolumab (3 mg per kg) on days 1 and 15, followed by surgery in one of the six participating hospitals in the Netherlands. Here, we report the independent primary efficacy endpoint of 3-year disease-free survival (time from surgery until disease recurrence or death from any cause) and the secondary endpoint of circulating tumour DNA (ctDNA) analysis. Overall survival (time from study enrolment until death from any cause) is reported as an exploratory post-hoc analysis. All endpoints were assessed in the per-protocol population (patients who met the eligibility criteria and received at least one cycle of therapy). The study is registered with ClinicalTrials.gov, NCT03026140, and has completed accrual.

Findings

From July 4, 2017, to July 18, 2022, 123 patients were screened, of whom 115 were treated and 111 were included in the per-protocol population. At the data cutoff (June 19, 2026), the postoperative median follow-up was 58·7 months (IQR 49·0–72·9). The 3-year disease-free survival was 100% (97·5% CI 100–100). After a median follow-up of 60·4 months (IQR 50·6–74·1), calculated from time of study enrolment, the 5-year overall survival was 100% (95% CI 100–100). In patients with available plasma samples, ctDNA was detected in 99 (92%) of 108 patients at baseline, and ctDNA clearance was observed in 44 (45%) of 98 patients after the first cycle in week 2 and in 80 (82%) of 97 patients after the second cycle before surgery. In patients with a pathological near-complete response and complete response, presurgery ctDNA clearance was observed in 19 (70%) of 27 patients and 60 (92%) of 65 patients, respectively. Assessment for minimal residual disease after surgery revealed that all patients were ctDNA negative.

Interpretation

In patients with locally advanced dMMR colon cancer, treatment with ipilimumab and nivolumab before surgery resulted in a 3-year disease-free survival and 5-year overall survival of 100%. These findings support neoadjuvant nivolumab plus ipilimumab as a potential standard of care for patients with locally advanced dMMR colon cancer.
