Esophageal cancer in Uruguay: a case-control study

Area of Science:

• Epidemiology
• Public Health
• Oncology

Background:

• Esophageal cancer presents a significant public health challenge in Uruguay, with high mortality rates.
• Established risk factors for esophageal cancer include heavy alcohol and tobacco consumption.
• The role of traditional beverage consumption, specifically maté, as a potential risk factor requires investigation.

Purpose of the Study:

• To investigate the association between maté consumption and esophageal cancer risk in Uruguay.
• To assess the independent effect of maté, controlling for alcohol and tobacco use.
• To examine dose-response relationships between maté consumption and esophageal cancer.

Main Methods:

• A case-control study was conducted involving 226 esophageal cancer patients and 469 controls.
• Interviews were conducted at the Oncology Institute of Montevideo between 1979 and 1984.
• Data on maté, alcohol, and tobacco consumption were collected and analyzed, controlling for confounding factors.

Main Results:

• Heavy tobacco and alcohol use were associated with elevated esophageal cancer risk in males (RR=10.8 and 10.3, respectively).
• Maté consumption showed an independent association with esophageal cancer in both sexes (OR=6.5 for males, OR=34.6 for females among heavy users).
• A significant dose-response relationship between maté consumption and esophageal cancer risk was observed in both genders.

Conclusions:

• Maté consumption represents an independent risk factor for esophageal cancer in Uruguay.
• The association between maté and esophageal cancer is particularly strong in heavy female consumers.
• Public health strategies may need to consider maté consumption patterns in esophageal cancer prevention efforts.
