NCT ID NCT06982768

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study looks at how a specific gene change (called hMLH1 hypermethylation) affects stomach cancer. Researchers will study 245 patients who had stomach cancer surgery to find links between lifestyle, genetics, and how the cancer behaves. The goal is to better understand why some stomach cancers resist standard chemotherapy and to develop a tool that predicts which treatments will work best for each patient.

Inclusion Criteria: * Patients who underwent elective gastrectomy for Stage I-IV gastric cancer. * Surgery performed at the General Surgery Unit of Fondazione Policlinico Universitario A. Gemelli IRCCS. * Procedures conducted between January 2017 and August 2023. * Only patients who have already undergone immunohistochemistry evaluation for expression of the components of the MMR complex (MLH1, PMS2, MSH2, and MSH6).
