Background: The number of older patients undergoing curative esophagectomy for esophageal cancer is increasing, and minimally invasive techniques are being increasingly used. The aim of this study is to compare postoperative outcomes after curative esophagectomy between older and younger patients.
Methods: Data was retrieved from the Dutch Upper Gastrointestinal Cancer Audit (DUCA), a national surgical outcome registry.
Background: Data on the age-specific incidence of esophageal cancer are lacking. Our aim was to investigate the age-stratified incidence, treatment, and survival trends of esophageal cancer in the Netherlands, with a focus on adults <50 years.
Material And Methods: Patients diagnosed with esophageal cancer were included from the nationwide Netherlands Cancer Registry (1989-2018).
New polymer-bioactive compound systems were obtained by immobilization of triazole derivatives onto grafted copolymers and grafted copolymers carrying betaine units based on gellan and N-vinylimidazole. For preparation of bioactive compound, two new types of heterocyclic thio-derivatives with different substituents were combined in a single molecule to increase the selectivity of the biological action. The 5-aryl-amino-1,3,4 thiadiazole and 5-mercapto-1,2,4-triazole derivatives, each containing 2-mercapto-benzoxazole nucleus, were prepared by an intramolecular cyclization of thiosemicarbazides-1,4 disubstituted in acidic and basic medium.
