Table 1 Classification of pseudomyxoma peritonei
SystemClassification
Ronnett et al[8]DPAM: PMP with mucinous ascites on the surface of peritoneum. No invasion. Indolent course. Best prognosis PMCA: Higher percentage of malignant cells. Poorer prognosis PMCA-I: Intermediate hybrid between DPAM and PMCA
WHOLow grade: Mucin pools with low grade dysplasia. Eighty-three percent of five-year OS High Grade: Mucin pools with high grade dysplasia. More likely for rupture and spillage into the peritoneal cavity. Sixty-eight percent of five-year OS
