BACKGROUND: The purpose of this retrospective evaluation was to assess the palliative effect of oral etoposide in heavily pretreated patients with squamous cell carcinoma of the head and neck. PATIENTS AND METHODS: Between October 1995 and February 2003, a total of 26 patients with metastatic and/or recurrent squamous cell carcinoma of the head and neck (SCCHN) were treated with oral etoposide. Therapy consisted of etoposide at a total dose of 100 mg daily for 7 days and was repeated every 4 weeks until progression of disease or for a maximum of 8 courses. Eighteen patients underwent primary surgery of the tumour followed by adjuvant irradiation or surgery after neoadjuvant radiochemotherapy. Eight patients had primary irradiation with or without concomitant chemotherapy. All patients previously received at least one palliative chemotherapy with cisplatin/5-floururacil (5-FU) or cisplatin/taxotere. Patients did not routinely receive anti-emetic medication. RESULTS: All patients were eligible for toxicity and survival assessment, and 24 of 26 patients for response evaluation according to an intention-to-treat principle. Two patients had a partial response (8 percent); disease was stable in 9 patients (35 percent) and progressed in 13 patients (50 percent). The median time to progression for all patients was 3 months (range, 2-54), and median overall survival was 10 months (range, 2-52). Toxicity was in general mild and moderate (Grade 1 and 2), except three patients, who experienced Grade 3 anaemia, and one patient who had Grade 3 thrombocytopenia without bleeding complications. Severe nonhematologic adverse reactions were not seen, except for alopecia. CONCLUSION: Our data suggest that oral etoposid is markedly effective, in regard to stabilization of disease and survival, and an excellent tolerated therapy for pretreated patients with recurrent and/or metastatic head and neck carcinomas. Its advantage over other commonly used and more intensive regimens such as 5-fluorouracil (5-FU) + cisplatin or taxane-containing combinations is its superior tolerance, in particular the incidence of nausea and vomiting, complete alopecia, and/or hematologic complications.
