Figure 4 Survival related to histological classification, age and appendiceal mucinous adenocarcinoma. A: Overall survival of the three histologic groups: Disseminated peritoneal adenomucinosis (DPAM), peritoneal mucinous carcinomatosis with intermediate or discordant features (PMCA-I/D) and peritoneal mucinous carcinomatosis (PMCA) (P = 0.001); B: Overall survival of the three age groups: < 40, 40-59 and ≥ 60 years (P = 0.011); C: Overall survival of the two appendiceal tumor groups: low-grade appendiceal mucinous neoplasm and mucinous adenocarcinoma (P = 0.008).
