Abstract
OBJECTIVE: We conducted a retrospective analysis to evaluate the efficacy and safety of cetuximab plus radiation with or without prophylactic percutaneous endoscopic gastrectomy in locally advanced squamous cell carcinoma of the head and neck patients who were not suitable to receive platinum.
PATIENTS AND METHODS: We reviewed the case records of 27 locally advanced squamous cell carcinoma of the head and neck patients treated with cetuximab plus radiation (RT) between January 2013 and July 2014. No patient was able to receive platinum because of renal dysfunction or other contraindications. Patients received an initial dose of cetuximab of 400 mg/m(2), followed by weekly doses of 250 mg/m(2). The total dose of radiotherapy was 66-70 Gy in five daily fractions of 2-2.12 Gy per week.
RESULTS: The incidence of leukopenia was significantly higher in patients without percutaneous endoscopic gastrectomy placement than in those with (67.5% vs. 7%, P = 0.002). The incidence of Grade 3 or 4 mucositis tended to be higher in patients without percutaneous endoscopic gastrectomy placement than in those with (83% vs. 47%, P = 0.058). Five of twelve patients without percutaneous endoscopic gastrectomy placement required interruption of treatment. More patients without percutaneous endoscopic gastrectomy placement had significantly >10% weight loss than patients with (75% vs. 27%, P = 0.013). The overall response rate was 56% in all patients. The 1-year progression-free survival rate was 30.6% in all patients.
CONCLUSIONS: Prophylactic percutaneous endoscopic gastrectomy-feeding tube placement could reduce the incidence of severe toxicities, including mucositis and weight loss, and avoid RT interruption. These results require confirmation in a larger study.
