Phase II trial of dose-dense paclitaxel, cisplatin, 5-fluorouracil, and leucovorin with filgrastim support in patients with squamous cell carcinoma of the head and neck.
BACKGROUND
The current study evaluated the feasibility and clinical activity of a combination of paclitaxel, cisplatin, 5-fluorouracil (5-FU), and leucovorin administered on a biweekly schedule to patients with recurrent or unresectable squamous cell carcinoma of the head and neck (HNSCC).


METHODS
Patients with recurrent or unresectable HNSCC were eligible if they had received a previous regimen of neoadjuvant chemotherapy, concurrent chemoradiotherapy, or no previous systemic therapy. Patients received paclitaxel (175 mg/m2 on Day 1), cisplatin (35 mg/m2 on Days 1 and 2), leucovorin (200 mg/m2 on Day 1), and 5-FU (1000 mg/m2 per day as a 48-hour continuous intravenous infusion on Days 1 and 2) every 2 weeks. Patients received subcutaneous filgrastim (300 microg per day) on Days 3-9 of each cycle. Treatment was administered on an outpatient basis for a maximum of six cycles.


RESULTS
Thirty-five patients received a combined total of 194 treatment cycles. Eighteen complete responses (51%) and 12 partial responses (34%) were documented, for an overall response rate of 86% (30 of 35 patients). The median progression-free survival duration was 14 months, and the median overall survival duration was 18 months. Two toxicity-related deaths were documented (one due to neutropenic sepsis and the other due to catheter-related pulmonary embolism). Grade 4 neutropenia was observed in one patient. Other severe (Grade 3 or 4) toxic effects included mucositis (14%), anemia (6%), thrombosis (6%), thrombocytopenia (3%), and neuropathy (3%).


CONCLUSIONS
The current dose-dense, four-agent, taxane-containing biweekly schedule was feasible and effective in patients with recurrent or unresectable HNSCC. However, given the single-center nature of the current study and the highly selected study population, further validation of these findings is recommended.
