¹Included 3 arterial reconstructions. 17 patients benefited from adjunctive radiotherapy;

²17% survival at 1 year if margins were positive (median survival: 6 mo) and 61.5% if margins were negative (median survival: 14 mo);

³Survival at 1 year: 39.6% if the vessel was not invaded, 11.3% if the media was invaded, and 5.5% if the intima was invaded;

⁴Median survival was 6.8 mo if the intima was invaded, 15.3 mo if the intima was spared, and 20.6 mo if there was no true vascular invasion;

⁵5-year survival rate: 23%;

⁶This mortality also includes arterial reconstructions (11 patients);

⁷5-year survival rate: 12%;

⁸3-year survival rate: 22%;

⁹5-year survival rate: 17.9%.
