Epidemiological Characteristics of Gastric and Pancreatic Cancers in Latin America

Epidemiological Characteristics of Gastric and Pancreatic Cancers in Latin America

Currently, there is no Brazilian or Latin American epidemiological data, such as clinical-pathological characteristics, standard treatments and outcomes of gastric cancer and pancreatic cancer in the region. The study aims to create a Latin American multicenter database to analyze epidemiological, clinical, and pathological data, treatments, outcomes, and biological information from patients with gastric and pancreatic cancer.

Patients diagnosed with gastric and gastroesophageal junction or pancreatic cancer after January 2019 at participating sites will be included. Data will be collected from medical records in selected centers that comprise different countries from Latin America. Data collection will begin on the time of site activation.

Patients recruited for this study will be identified in the participating sites. Data from clinical, demographic, and socioeconomic variables will be collected. Also, data on treatments performed and outcomes will be abstracted. The patient data sources will be the medical records of the patients. Patients will continue to receive treatment and clinical evaluations for gastric and gastroesophageal junction or pancreatic cancer according to what is determined by their medical team, according to the usual standards of treatment and clinical practice of each center.

Inclusion Criteria:

• ≥18 years
• Histological diagnosis of gastric and gastroesophageal junction cancer (Cohort A) or histological diagnosis of pancreatic cancer (Cohort B);
• Advanced disease diagnosis from January 2019: patients can be included prospectively. Advanced disease is defined as metastatic disease or locally advanced disease not amenable to curative therapy;
• Availability of adequate medical data for data collection.

Exclusion Criteria:

• Synchronous invasive tumor or second primary tumor in the last three years (except thyroid tumors or non-melanoma skin);
• Nonepithelial histology in Cohort A: Sarcoma, GIST, lymphoma, and tumors of neuroendocrine origin;
• Nonepithelial histology in Cohort B: Sarcoma, GIST, lymphoma, pancreatoblastoma, and tumors of neuroendocrine origin.
