Cancer gene hunt: could tumor maps guide better GI cancer treatment?
NCT ID NCT05489250
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looked at genetic mutations in tumors from 565 people with advanced gastrointestinal cancers, including liver, bile duct, gallbladder, pancreas, esophagus, and stomach cancers. The goal was to see how often these mutations could be targeted by existing drugs and to track whether using genetic information changed treatment decisions. The study was terminated early, so the full impact is unclear.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors choose more targeted treatments for gastrointestinal cancers based on a patient's tumor genetics.
- What could go wrong
- The study was terminated early, so results may be limited. It was observational, not testing a new treatment directly, so benefits are uncertain.

Who is studied
The PLATON Network and its associated pilot study (clinicaltrials.gov:. NCT04484636) enrolls national-wide participants of both sexes and ages over 18 years. All participants are patients diagnosed with hepatocellular cancer (HCC) or intra-/extrahepatic cholangiocellular carcinoma (CCA) or gallbladder carcinoma (GBCA) or pancreatic cancer (PanCa) or esophagogastric cancer (EC/GC). At the time of enrolment life expectancy is at least 6 months and no local curative therapy is available.

Inclusion Criteria: * Histologically confirmed diagnosis of hepatocellular carcinoma or intra- cholangiocarcinoma, extrahepatic cholangiocarcinoma or gallbladder carcinoma or pancreatic ductal adenocarcinoma or esophagogastric adenocarcinoma in the advanced setting (adjuvant or neoadjuvant therapy is allowed if completed 6 months prior to enrolment) and no local curative therapy available * Standard first line therapy is planned, or patient is currently receiving first-line therapy * Available tumor-genomic profile ( ≥50-gene panel assay; approved and assessed by central review), unless central tumor genomic profiling is done within a sub-study * ECOG 0-2 * Life expectancy ≥ 6 months Exclusion Criteria: * Not able to understand all implications of study participation * No written informed consent * Age \< 18 years
