Prognostic factors and efficacy of postoperative chemotherapy in patients with gastric cancer with positive peritoneal cytology after gastrectomy

Figure 1 Flow diagram of gastric cancer patients with peritoneal lavage cytology-positive who underwent gastrectomy. CY1: Peritoneal lavage cytology-positive; P1a: Localized peritoneal metastasis; R2: Residual tumor (gross/pathological) with peritoneal dissemination or positive margins in locally advanced disease; M1: Metastasis to distant organs; CY0: Peritoneal lavage cytology-suspected false positive; D0 LN: Lymph node (D0); CDDP: Cisplatin; DOC: Docetaxel.
