Radiation of jejunal interposition in T3-T4 upper aerodigestive tumours

30 patients with T3 and T4 tumours of the upper aero-digestive tract had their tumours resected by pharyngolaryngectomy. This was followed by reconstruction of a gullet or creation of a siphon as a tracheohypopharyngeal shunt for voice restoration with a free jejunal autograft. All patients were treated postoperatively with 60Co gamma radiation, 6 MeV photons or 7.5 to 10 MeV electrons of a β-tron, with a dose of 50-65 Gy in the area of the primary tumour and 50-65 Gy to the neck. 4 patients refused further treatment after a depth dose of between 16 and 32 Gy. Local recurrence occurred in 40% of cases. The survival rate was 36.6% (11/30) after a mean follow-up time of 21.5 months, although 2 patients died of inter-current diseases without recurrence of their tumours. The results obtained justify active surgical intervention with postoperative irradiation even at an advanced stage of the tumour. (author)
