Survival curves according to metastatic site diagnosed by staging laparoscopy. a shows survival curve of patients with locally advanced PDAC (LA, solid black line), with positive cytology (CY, solid grey line), with peritoneal metastasis (P, dotted grey line), and with liver metastasis (L, dotted black line). There were significant differences between the survival curves of P and CY (p = 0.007) and P and LA (p = 0.04) groups. b shows survival curves of patients with locally advanced PDAC and positive cytology (LA + CY, solid black line) and with peritoneal metastasis and liver metastasis (P + L, dotted black line). The survival curve in LA + CY groups was significantly better than in P + L groups (p = 0.011)
