BACKGROUND: The authors studied the efficacy of neoadjuvant chemotherapy, consisting of a taxane, cisplatin, and 5-fluorouracil (5-FU) (the TPF regimen) followed by concurrent chemoradiation, in 2 separately designed and synchronously executed phase 2 trials for stage III and IVA/IVB nasopharyngeal cancer (NPC).
METHODS: Patients with newly diagnosed NPC were accrued to 2 trials, 1 for patients with stage III disease and the other for patients with IVA/IVB disease. All patients received TPF (docetaxel 75 mg/m(2), cisplatin 75 mg/m(2), and 5-FU 2500 mg/m(2) every 3 weeks for 3 cycles) followed by cisplatin 40 mg/m(2) per week concurrently with either 3-dimensional conformal radiation therapy or intensity-modulated radiation therapy.
RESULTS: From January 2007 to July 2011, 52 eligible patients with stage III NPC and 64 eligible patients with nonmetastatic stage IV NPC were accrued. With a median follow-up of 32.9 months, the 3-year overall survival rates were 94.8% (95% confidence interval [CI], 87.6%-100%) and 90.2% (95% CI, 81.8%-98.6%) for the stage III NPC group and the IVA/IVB NPC group, respectively. The 3-year progression-free survival, distant metastasis-free survival, and local progression-free survival rates were 78.2% (95% CI, 64.6%-91.8%), 90.5% (95% CI, 79.7%-100%), and 93.9%(87.1%-100%), respectively, for patients with stage III NPC and 85.1% (95% CI, 75.1%-95.1%), 88% (95% CI, 78.6%-97.4%), and 100%, respectively, for patients with stage IVA/IVB NPC. The most common severe (grade 3/4) hematologic and nonhematologic adverse events were neutropenia (64 patients; 55.2%) and nausea/vomiting (23 patients; 19.8%).
CONCLUSIONS: Neoadjuvant TPF followed by concurrent chemoradiation was well tolerated and produced encouraging outcomes in patients with locally advanced NPC in this hypothesis-generating study. The authors concluded that randomized controlled trials are warranted to definitively confirm this aggressive and potentially efficacious strategy.
