- Ages 18 years and older
- All sexes
- Healthy volunteers accepted
- Adult, Older adult
Study population: Cohort A - Opportunistic screening cohort A cohort of FIT-positive individuals undergoing colonoscopy for colorectal cancer screening, with the addition of opportunistic EGD during the same procedure. Cohort B - Gastric cancer cohort A retrospective cohort including all patients diagnosed with gastric adenocarcinoma in the institution over a 11-year period.
Who may be able to join
- Cohort A:
- Eligible participants were adults aged 50 to 75 years or older who had been referred for colonoscopy as part of the national colorectal cancer screening programme, following a positive FIT. To be included, individuals also needed to provide informed consent and agree to undergo an EGD endoscopy for the screening of potential upper gastrointestinal precancerous conditions or lesions.
- Cohort B:
- Patients with gastric adenocarcinoma, diagnosed and treated at Unidade Local de Saúde do Alto Alentejo between 2015 and 2025.
Who cannot join
- Cohort A:
- Exclusion criteria included a prior diagnosis of gastric cancer, as well as any condition that would prevent the safe performance of the EGD or the collection of gastric mucosal biopsies. Previous EGD was not listed as an exclusion criterion.
- Cohort B:
- Other types of gastric tumors.
- Gastric involvement from metastatic disease of another primary tumor.

What is being measured
The primary outcome is the main question the study is designed to answer.
Stage distribution at diagnosis
Distribution of gastric cancer stages at diagnosis (Stage I-IV) according to TNM classification (expressed as percentage of patients per stage).
Measured: At diagnosis (2015-2020)
Treatment patterns
Types of treatment received by patients with gastric cancer, including surgery, chemotherapy, radiotherapy, and palliative care
Measured: During initial treatment period (2015-2020)
Overall survival
Overall survival of patients diagnosed with gastric cancer (measured in months).
Measured: From diagnosis up to last follow-up (2015-2020)
