Effektivitet og overlevelsesanalyse af perioperativ behandling af lokalt avanceret mave- eller gastroøsofageal junction-kræft (GC/GEJC)

19. september 2026 opdateret af: LIN YANG, Cancer Institute and Hospital, Chinese Academy of Medical Sciences

Analyse af effektivitet og overlevelsesprognose for perioperativ behandling af lokal fremskreden mave- eller gastroøsofageal junction adenokarcinom

This study is a single-center, retrospective cohort study. The purpose is to evaluate different perioperative treatment options on the efficacy and survival prognosis of locally advanced GC/GEJC, clarify whether the tumor regression grade can influence survival of patients using neoadjuvant therapy. Moreover, we aim to explore the clinical and pathological characteristics that will affect the long-term survival benefit of patients who underwent perioperative treatment.
