“…Results are encouraging with a 5-ys-OS ranging from 62.5 to 100% for low grade PMP and from 0 to 65% for high grade disease . This differentiation is crucial for the evolution of disease; low grade tumours are slow growing and indolent differently from those high grade, fast growing and aggressive (Sugarbaker and Chang, 1999;Witkamp et al, 2001;Güner et al, 2005;Moran et al, 2008;Moran and Cecil, 2003;Murphy et al, 2007;Baratti et al, 2008;Elias et al, 2008;Loungnarath et al, 2005;Smeenk et al, 2007;Stewart et al, 2005;Yan et al, 2006). The goal of the surgical cytoreduction is to remove all the visible tumor by the following procedures: right subdiaphragmatic and parietal peritonectomy, left subdiaphragmatic and parietal peritonectomy,greater omentectomy with splenectomy, lesser omentectomy and stripping of the omental bursa, andpelvic peritonectomy with salpingo-oophorectomy in women.…”
