Sample BCOP Question 2
AL is a Caucasian 42 year old female who has a history of a gastric ulcer secondary to Helicobacter pylori infection. When questioned about her dietary habits, AL replies that she eats a burger and fries daily at the cafeteria and drinks 1-2 beers/week socially. In addition, her father was diagnosed with gastric cancer at age 51. Which of the following risk factors dose AL have for gastric cancer?
- Ethnicity, H. pylori infection, diet
- H. pylori infection, alcohol use, family history
- Ethnicity, H. pylori infection, alcohol use
- H. pylori infection, diet, family history
Answer: D
Rationale:
- H. pylori infection, a diet high in salted, fried or preserved foods and low in fruits and vegetables, and a positive family history are all risk factors for gastric cancer.
- Gastric cancer is one of the least common cancers diagnosed in North America whereas it is rampant in other parts of the world such as Asia. It is more commonly diagnosed in Asian/Pacific Islanders, Hispanics and African Americans. Therefore, AL would not be at high risk due to her ethnicity.
- While a meta-analysis showed a lack of association between moderate alcohol consumption and gastric cancer risk, there was a positive association with heavy alcohol drinking (≥ 4 drinks/day) especially for non-cardiac gastric cancers. AL would not be considered a heavy drinker.
High-Yield Core Concept:
- Risk factors for gastric cancer include H. pylori infection, smoking, a diet high in salted, fried or preserved foods and low in fruits and vegetables, positive family history, and heavy alcohol use.
- Gastric cancer is also one of the least commonly diagnosed cancers in North America whereas it is widespread in Asia.
High-Yield Fast Fact(s):
- China has the highest number of newly diagnosed gastric adenocarcinoma patients in the world.
