Concurrent chemoradiotherapy with conventional fractionated radiotherapy and low-dose daily cisplatin plus weekly docetaxel for T2N0 glottic cancer

Background: To assess the efficacy of concurrent chemoradiotherapy (CCRT) with daily low-dose cisplatin (CDDP) plus weekly docetaxel (DTX) for patients with T2N0 glottic cancer. Methods: Between January 2004 and December 2013, 62 treatment-naive patients with histologically proven T2N0 glottic cancer were treated with concurrent chemoradiotherapy. Radiation therapy (RT; 2 Gy daily fractions up to a total dose of 66 Gy) was administered in combination with daily low-dose CDDP (6 mg/m(2), five times a week), plus weekly DTX (10 mg/m(2)) for up to 4 weeks from the commencement of RT. Results: Median duration of follow-up was 70 months. The actuarial 3-year and 5-year overall survival rates were 95% and 93%. The 3-year and 5-year cause-specific survival rates were both 100%. The actuarial 3-year and 5-year local control rates were 94% and 94%, respectively. Hematologic toxicity (neutoropenia of severity >= Grade 3) was observed in 8% of the patients, and non-hematologic toxicity (radiation mucositis of severity >= Grade 3) developed in one patient (2%). Radiation dermatitis of severity >= Grade 3 and laryngeal necrosis developed in one patient. Conclusion: CCRT with weekly DTX and low-dose CDDP appears to be a practical and safe modality and is expected to improve local control.
