“…For stage I addition of surgery to conventional treatments (chemo-radiation) improved 5-year survival rate from 11.3% to 44.9%, so Authors concluded that patients with resectable disease in stage I should be referred to surgery [Rostad, 2004]. The same conclusion is reported by Leo and Pastorino in their review [Leo & Pastorino, 2003] High 5 years survival rate was reported also by Tsuchiya in a retrospective series of patients treated with a similar protocol [Tsuchiya, 2005]. Interestingly, Authors reported only 10% of local failure after surgery, which is lower than commonly reported after chemo-radiation therapies alone.…”
