Prognostic value and therapeutic efficacy of interstitial circulating tumor cells in patients with advanced gastric cancer

Figure 3 Relationship between interstitial circulating tumor cells and gastric cancer. A: Interstitial circulating tumor cells (I-CTCs) expression status before treatment; B: I-CTCs and prognostic receiver operating characteristic curves of patients with advanced gastric cancer (GC); C: Two-year overall survival curves of I-CTCs-positive and negative groups of patients with advanced GC; D: Two-year disease-free survival curves of I-CTCs-positive and negative groups of patients with advanced GC. I-CTC: Interstitial circulating tumor cell; AUC: Area under the curve; OS: Overall survival; DFS: Disease-free survival.
