J J Bonenkamp,John J. Hermans,M. Sasako,C.J.H. van de Velde,K. Welvaart,I. Songun,S. Meyer,JThM Plukker,P. van Elk,Huug Obertop,D. J. Gouma,J. J. B. van Lanschot,C.W. Taat,P. W. de Graaf,M.F. von Meyenfeldt,H. W. Tilanus +15 more
TL;DR: The results in Dutch patients do not support the routine use of D2 lymph-node dissection in patients with gastric cancer, as recommended by the Japanese medical community.
Journal ArticleDOI
Randomised comparison of morbidity after D1 and D2 dissection for gastric cancer in 996 Dutch patients
J. J. Bonenkamp,I. Songun,K. Welvaart,C.J.H. van de Velde,Jo Hermans,M. Sasako,JThM Plukker,P. van Elk,Huug Obertop,Dirk J. Gouma,C.W. Taat,J. J. B. van Lanschot,S. Meyer,P. W. de Graaf,M.F. von Meyenfeldt,H. W. Tilanus +15 more
TL;DR: Morbidity and mortality differences persisted in almost all subgroup analyses, and D2 dissection should not be used as standard treatment for western patients.
Journal ArticleDOI

Gouma,J. J. B. van Lanschot,C.W. Taat,P. W. de Graaf,M.F. von Meyenfeldt,H. W. Tilanus,M. Sasako +18 more
TL;DR: Overall, extended lymph node dissection as defined in this study generated no long-term survival benefit, and the associated higher postoperative mortality offsets its long- term effect in survival.
Journal ArticleDOI
Preparation and properties of arylgold compounds. Scope and limitations of the auration reaction
TL;DR: Several ligand-free mono-aryl gold dichlorides (RC6H4AuCl2)2 (R = H, Me, Et, i-Pr, t-Bu, Ph) have been prepared from arenes and AuCl3; contrary to earlier reports, adding ligands is not necessary in order to obtain thermally stable products.
Journal ArticleDOI
The vascularization of a gastric tube as a substitute for the esophagus is affected by its diameter.
TL;DR: In this paper, the quality of the vascularization of the gastric tube, used as a substitute for the oesophagus after esophagectomy, depends on its diameter.
