GERD may increase the threat of some cancers
03 March, 2021
In a new study, researchers found evidence of a connection between GERD and cancers of the larynx and esophagus. The study, which looks in the journal Cancer, increases an existing body of evidence.
The researchers hope that, if their results are confirmed, they might “inform clinical surveillance of GERD patients and recommend new avenues for prevention of these malignancies.”
Symptoms of GERD
GERD is a type of chronic gastrointestinal disease that causes the contents of the tummy to rise into the esophagus.
Researchers estimate that GERD impacts 18.1% to 27.8% of people in the U.S.
People with GERD may encounter heartburn or regurgitation, as well as chest pains, nausea, problems swallowing, or a good persistent cough.
GERD occurs whenever a person’s more affordable esophageal sphincter weakens or relaxes at the incorrect times. Having overweight or obesity, carrying a child, and smoking will be each risk factors for GERD.
Researchers experience linked GERD to laryngeal squamous cell carcinoma (LSCC), a type of cancers of the aerodigestive tract. This area of the body contains the organs and cells of the respiratory tract and upper digestive system.
The authors of the present study remember that earlier findings have already been inconsistent.
They make clear that “Most previous studies have been tied to size, study style, or insufficient control for important potential confounders, [such as] tobacco use and alcohol consumption, limiting the effectiveness of the inference.”
In addition, no analyses had investigated the practical link between GERD and esophageal squamous cell carcinoma (ESCC), another aerodigestive tract cancer.
Extracting the data
To handle this, the researchers conducted a good potential study, drawing on info from the NIH‐AARP Diet plan and Health Research, which began in 1990s, with questionnaires delivered to members of the American Association of Retired Persons, or AARP.
The participants were aged 50-71 years and located through the entire U.S. The researchers built utilization of the responses from 490,605 participants, 92.6% of whom determined as non-Hispanic white.
The questionnaire asked about various risk factors linked to GERD, such as for example alcohol consumption, tobacco use, diet, body shape, and medical issues.
The researchers then cross-checked this info with data from Medicare claims linked to GERD and also estimated the presence of GERD for all those not eligible for Medicare. Overall, the team approximated that 23.7% of the sample they analyzed possessed a brief history of GERD.
They then used info from state cancer registries to determine if the participants had developed LSCC, ESCC, or a kind of cancer called esophageal adenocarcinoma (EADC) over the next 16 years.
