Studie Bevolking

Approximately 300 adult patients with histologically confirmed, stage II to IVB gastric/GEJ adenocarcinoma will be enrolled from 10-15 oncology clinics of large public and private hospitals, covering diverse geographic areas, in Greece.

Beschrijving

Inclusion Criteria:

  • Patients aged ≥18 years upon gastric/GEJ adenocarcinoma diagnosis.
  • Written signed and dated informed consent by the patient (or their legally acceptable representative, as applicable). For deceased patients on the date of study entry a waiver of consent must be approved by the Hospital EC/IRB.
  • Patients diagnosed with histologically confirmed, stage II to IVB adenocarcinoma of gastric/GEJ, between June 1st, 2025 and the end of the recruitment period (Q3 2027).

Exclusion Criteria:

  • Patients who participate or participated during the data collection period (prospective and retrospective) in any clinical investigation/clinical trial that includes interventions that fall outside the everyday clinical practice.
  • Patients who have participated in the design and/or the conduct of the study.
  • Patients with another primary malignancy within the last 5 years, for which systemic anticancer treatment is required after the diagnosis of gastric/GEJ cancer.
