Overall survival. Kaplan-Meier plot for patients according to their peritoneal disease status. Median OS of patients without peritoneal disease and of patients who did convert after neoadjuvant therapy was not reached. In contrast, median OS was reduced to 13 months (95% CI 8.7–16.7) in patients without conversion and was 16 months (95% CI 12–20.5) in patients with peritoneal metastasis without difference between the two groups (p = .364)
