[Radiotherapy, radiotherapy combined with surgery, radiotherapy combined with chemotherapy in the treatment of carcinoma of the pyriform sinus. A retrospective study].
A rectrospective analysis was performed of the results of 104 consecutive patients with carcinoma of the pyriform sinus, who underwent radiation therapy. Thirty-four patients underwent radical surgery and postoperative radiation therapy (group 1); 36 patients received radical radiation therapy alone (group 2); neoadjuvant chemotherapy was administered prior to full-dose radiation to 20 patients (group 3); 14 patients received palliative radiation therapy (group 4). Loco-regional control and survival rates at 5 years were 60.4% and 34.3% in group 1, 23.8% and 23.8% in group 2, 17.5% and 23.8% in group 3; no patients in group 4 survived at 5 years. Patients in group 1 experienced significantly better survival and local control than those in groups 2 and 3. No differences were observed between groups 2 and 3. Loco-regional recurrence was the main cause of failure in group 2 (69.4%) and 3 (70.0%). In group 1, 20.3% of cases developed distant metastases. Overall 5-year survival rate was 23.7%, confirming the poor prognosis of this disease. These results provide further support to the need of improving prevention and early diagnosis to improve both results and outcome in patients with carcinoma of the pyriform sinus.
