A total of 100 pts matched inclusion criteria. Median age was 61 years (range 43-84) and 75% were male. Seventy-two (72%) pts underwent IMRT (90% concurrent CT) while 28 (28%) pts have been treated with TORS followed by PORT IMRT (61% concurrent CT). Tumor and patient characteristics have been reported in Table 1. After a median follow up of 24 months (range 1.4-74.4 months), all pts were alive and 86% and 87% resulted without disease in IMRT and TORS group, respectively. Locoregional recurrences occurred in 11% and 12% of pts treated with IMRT and TORS, respectively. Acute and early-late toxicity profile have been reported in Table 2. Eight (12%) and 4 (4%) pts required enteral nutrition during the radiation course in the IMRT and TORS group, respectively. Twenty one (30%) and two (7%) pts lost more than 10% (G3 toxicity) of their baseline value in the IMRT and TORS cohort, respectively. Tracheostomy, enteral nutrition and oesophageal stricture occurred at any time during the follow up period in 6%, 3%, 0% and 1%, 3%, 0% pts treated with IMRT and TORS, respectively.
