ISLAMABAD, May 13 (Online): Researchers say a simple oral rinse may help detect stomach cancer early.
\nAn oral rinse to help detect stomach cancer is in the early stages of research.
\nGastric cancer is often not caught until it is in its late stages and treatment is limited.
\nThe success rate of the oral rinse still needs to be tested in more extensive studies.
\nAn oral rinse could provide early detection of gastric cancer, according to a study that will be presented at Digestive Disease Week 2024.<\/p>\n
This is early research that hasn\u2019t been published yet in a peer-reviewed journal and this \u201cswish and spit\u201d rinse is not yet available.<\/p>\n
In their study, researchers analyzed bacterial samples from 98 people \u2013 30 with known gastric cancer, 30 with premalignant gastric conditions, and 38 people without gastric health issues.<\/p>\n
The researchers reported there was little difference in the microbiomeTrusted Source of precancerous and cancerous groups, but they said there were distinct differences between those groups and the healthy control group.<\/p>\n
The scientists said their findings suggest that the changes in the microbiome could occur as soon as the stomach environment starts to undergo changes that will eventually develop into cancer.<\/p>\n
They added that the research indicates that oral bacteria could be a biomarker for gastric cancer risk.<\/p>\n
The researchers plan to conduct more extensive studies to ensure the findings are generalizable to a broader population.<\/p>\n
Reaction to potential oral rinse test for gastric cancer
\n\u201cThis is a very intriguing and important study since we have no known sensitive methods, other than endoscopy, to detect gastric cancer or pre-gastric cancer lesions,\u201d said Dr. Anton Bilchik, a surgical oncologist as well as the chief of medicine and the director of the Gastrointestinal and Hepatobiliary Program at Providence Saint John\u2019s Cancer Institute in California. \u201cA mouth rinse also sounds simple and easy to perform compared with an invasive procedure.\u201d<\/p>\n
\u201cThe microbiome (trillions of bacteria) in our body plays an important role in our immune system and the prevention of cancer, but there are clearly some bacteria that predispose us to cancer,\u201d Bilchik, who wasn\u2019t involved in the study, told Medical News Today. \u201cA better understanding of these bacteria and the ability to detect them using a non-invasive technique potentially allows screening of large populations, particularly those at risk for developing gastric cancer.\u201d<\/p>\n
Dr. Elliot Newman, the chief of surgical oncology at Northwell Lenox Hill Hospital in New York, agrees that the researach is promising, but he cautions that more extensive studies are needed.<\/p>\n
\u201cIt looks like the researchers used the samples to see each group\u2019s shared characteristics,\u201d Newman, who wasn\u2019t involved in the study, told Medical News Today. \u201cThey could then compare other samples to see where they were \u2014healthy, precancerous, or cancerous.\u201d<\/p>\n
\u201cWork like this is always exciting, but we have to see what happens in the long term,\u201d he added. \u201cIn theory, someone could have the rinse and it can pick up changes in the stomach that might be precancerous. If we can do that, we can cure everyone.\u201d<\/p>\n
What to know about gastric cancer
\nGastric cancer, also known as stomach cancer, starts in the cells lining the stomach, according to the National Cancer InstituteTrusted Source.<\/p>\n
There are several different types of stomach cancer, but the most common is adenocarcinoma. When it begins at the top of the stomach, it is called gastric cardia cancer. When it starts in other sections, it is called non-cardia gastric cancer.<\/p>\n
Typically, stomach cancer isn\u2019t detected until the tumor has grown to a large size or the cancer has metastasized outside the stomach, according to the American Cancer SocietyTrusted Source.<\/p>\n
Although many people do not have signs of stomach cancer before diagnosis, if they do, they may experience:<\/p>\n
Poor appetite
\nUnexplained weight loss
\nAbdominal pain
\nVague discomfort in the abdomen, usually above the navel
\nFeeling full after eating only a small meal
\nHeartburn or indigestion
\nNausea
\nVomiting, with or without blood
\nSwelling or fluid build-up in the abdomen
\nBlood in the stool
\nAnemia
\nJaundice if the cancer spreads to the liver<\/p>\n
How stomach cancer is treated
\nWhen the cancer is detected and treated while it remains in the stomach, the five-year survival rate is 75%, according to the American Cancer SocietyTrusted Source.<\/p>\n
If detection and treatment do not start until after the cancer has spread outside the stomach, the five-year survival rate drops to 35%.<\/p>\n
When the cancer metastasizes to distant areas of the body, the five-year survival rate plummets to 7%.<\/p>\n
Stomach cancer treatment includes:<\/p>\n
Chemotherapy
\nRadiation
\nImmunotherapy
\nTargeted drug therapy
\nSurgery
\nHyperthermic Intraperitoneal chemotherapy
\nTreatment for stomach cancer often includes two or more types of treatment.<\/p>\n","protected":false},"excerpt":{"rendered":"
