This observational study is looking into the biology of upper gastrointestinal (GI) cancers, which include stomach and esophageal cancers. Researchers are studying tissue samples from biopsies and blood samples to understand the role genes and proteins play in these cancers. You might be able to join if you are over 18 and have been diagnosed with gastric (stomach) or esophageal cancer, or if you have a high inherited risk for these cancers. The study aims to understand how p53 and NER activity, which are related to cell processes, are involved in these cancers. The current recruitment status is unclear.

Study design

This is an observational study with a planned enrollment of 100 participants. It is not a treatment study, but rather focuses on understanding the biology of the cancers.

What's involved

Participants will undergo a blood draw and/or a tissue tumor biopsy. The record does not specify the number of visits or the duration of participation.

Compensation

Not stated in the trial record.

Follow-up

The primary endpoints (p53 and NER activity) are measured at the time of sample collection. No further follow-up is specified.
