Medical or surgical handling of severe heartburn prevents cancer of the esophagus, a study from Karolinska Institutet amongst almost 1 1000000 Nordic patients reveals. The results are published inward the scientific mag JAMA Oncology.
Pathological heartburn together with acid reflux affects 10-20 per cent of the adult population. Long together with severe reflux is the strongest demand chances ingredient for cancer of the esophagus (type adenocarcinoma), an aggressive cancer that is hard to treat.
Reflux is unremarkably treated amongst medicine to brand the tummy contents less acidic, which unremarkably eliminates or reduces symptoms. One option is to accept an functioning (anti-reflux surgery) which prevents the tummy contents from coming upwards into the esophagus. Previous studies accept non conclusively demonstrated that these treatments forestall esophageal cancer, but the studies accept non been sufficiently large or had plenty follow-up fourth dimension to ensure that conclusions tin sack survive drawn on whatever long-term cancer-preventive effects.
In the introduce study, researchers used wellness information records from 1964 to 2014 from the 5 Nordic countries. Of the to a greater extent than than 940,000 patients amongst reflux inward the study, nigh 895,000 received medical handling together with of those nearly 2,370 patients (0.3 per cent) developed cancer of the esophagus during the follow-up period. The demand chances of cancer of the esophagus decreased over fourth dimension next handling together with was like to that of the corresponding population afterward xv years or to a greater extent than inward those who received medication.
Of the to a greater extent than than 48,400 patients who had anti-reflux surgery, 177 (0.4 per cent) developed cancer of the esophagus during the follow-up period. The demand chances of esophageal cancer clearly savage too inward this grouping together with was at the same score every bit inward the corresponding population xv years or to a greater extent than afterward the operation.
When the patients amongst reflux who had an functioning were compared amongst those amongst reflux who received medication, the patients who had been operated on had a slightly higher demand chances of esophageal cancer during the entire follow-up period, but the demand chances did non growth over time. This is in all probability caused yesteryear the fact that the operated patients had to a greater extent than serious reflux from the beginning.
"The results demonstrate that effective medical or surgical handling of reflux prevents cancer of the esophagus. But because the individual's demand chances of developing esophageal cancer is low, fifty-fifty inward those amongst reflux disease, the results create non justify treating reflux exclusively every bit a cancer-preventive measure. The symptoms together with complications of reflux illness should proceed to principle treatment," says John Maret-Ouda, MD together with scientist at the Department of Molecular Medicine together with Surgery at Karolinska Institutet inward Sweden together with the foremost writer of the study.
However, he points out that for the small-scale per centum of people amongst severe reflux inward combination amongst other demand chances factors for esophageal cancer, such every bit obesity, manful mortal sex together with mature age, effective together with continuous medical handling or an functioning to process reflux is recommended.
"Previous enquiry results accept shown misfortunate cancer-preventive effects from anti-reflux surgery. The divergence immediately is that for the foremost fourth dimension nosotros tin sack demonstrate statistically pregnant results because nosotros accept a sufficiently large study amongst a long follow-up menstruation of over xv years next the operation," says Jesper Lagergren, consultant surgeon together with professor at the Department of Molecular Medicine together with Surgery, Karolinska Institutet, who led the study.
The enquiry is funded yesteryear the Nordic Cancer Union, the Swedish Research Council together with the Swedish Cancer Society.
