TL;DR: PET imaging may differentiate responding and nonresponding tumors early in the course of therapy by avoiding ineffective and potentially harmful treatment, this may markedly facilitate the use of preoperative therapy, especially in patients with potentially resectable tumors.
Journal ArticleDOI
Histologic tumor type is an independent prognostic parameter in esophageal cancer: lessons from more than 1,000 consecutive resections at a single center in the Western world.
J. R. Siewert,Hubert J. Stein,Marcus Feith,Bjorn L. D. M. Bruecher,Holger Bartels,Ulrich Fink +5 more
TL;DR: Esophagectomy for esophageal cancer has become a safe procedure in experienced hands and has a better long-term prognosis after resection than squamous cell carcinoma.
Journal ArticleDOI
Metabolic imaging predicts response, survival, and recurrence in adenocarcinomas of the esophagogastric junction.
Katja Ott,Wolfgang A. Weber,Florian Lordick,Karen Becker,Raymonde Busch,Ken Herrmann,Hinrich Wieder,Ulrich Fink,Markus Schwaiger,J. R. Siewert +9 more
TL;DR: Changes in tumor metabolic activity during chemotherapy predict response, prognosis, and recurrence, and provide the basis for clinical trials in which preoperative treatment is changed for patients without a metabolic response early in the course of therapy.
Journal ArticleDOI
Prognostic relevance of systematic lymph node dissection in gastric carcinoma
TL;DR: Radical lymphadenectomy improves survival in patients with UICC gastric cancer stages II and IIIA, and should be the recommended treatment for such patients.
