XParTS: Capecitabine/Cisplatin(XP) for Recurrent Gastric Cancer
Phase II Study to Evaluate Efficacy and Safety of Capecitabine/Cisplatin Combination Therapy in Gastric Cancer Patients Who Relapsed After S-1 Adjuvant Chemotherapy (XParTS)

    Phase 2
  • Study Type

  • Status

    Unknown status
  • Study Participants

The aim of this study is to evaluate efficacy and safety of Capecitabine/Cisplatin for gastric cancer patients who relapsed after adjuvant chemotherapy by S-1.
S-1/Cisplatin (SP) is one of the standard treatments of advanced gastric cancer. However, evidence of SP on gastric cancer recurrence after adjuvant therapy by the same drug (S-1) is not established. The aim of this study is to evaluate the efficacy and safety of Capecitabine/Cisplatin (XP) for gastric cancer patients who relapsed after adjuvant chemotherapy by S-1.
