biostudies-literatureUnknown21(2)Nozaki SAkita University<h4>Background</h4>Poor oral health is an independent risk factor for upper-aerodigestive tract cancers, including esophageal cancer. Several studies have investigated short-term outcomes after esophagectomy and the impact of periodontal disease, but few have examined the impact of periodontal disease on long-term outcomes. The purpose of this study was to investigate the rate of periodontitis among esophagectomy patients and the prognostic value of periodontitis and its effect on prognosis after esophagectomy.<h4>Methods</h4>A total of 508 patients who underwent esophagectomy received oral health care from a dentist before cancer treatment at Akita University Hospital between January 2009 and December 2021. We assessed the presence and severity of the patients' periodontitis and divided tEsophagus : official journal of the Japan Esophageal Society120-130https://www.ebi.ac.uk/biostudies/studies/S-EPMC10957679biostudies-literaturePretreatment periodontitis is predictive of a poorer prognosis after esophagectomy for esophageal cancer.PMC10957679Nagaki YWakita ALiu JFukuda MMinamiya YTakano HSato YTakahashi TSasamori RNomura KSasaki YIgarashi HKonno YNozaki SfalsePretreatment periodontitis is predictive of a poorer prognosis after esophagectomy for esophageal cancer.<h4>Background</h4>Poor oral health is an independent risk factor for upper-aerodigestive tract cancers, including esophageal cancer.
