“…Prior surgical score has been identified as a prognostic indicator of survival in one study (Look et al, 2004). Median and 5-year survival rate varies from 18-54 months and 12-66% respectively (Piso et al, 2004;Raspagliesi et al, 2006;Di Giorgio et al, 2008;Tentes et al 2010, Ryu et al, 2004Zanon et al, 2004;Rufian et al, 2006;de Bree et al, 2003;Bae et al, 2007;Ceelen et al, 2009) ( Table 2).
