Show moreBackground. The radiation and concomitant high-dose intra-arterial or intravenous cisplatin (RADPLAT) phase III trial compared intra-arterial (IA) to intravenous (IV) cisplatin-based chemoradiation for head and neck cancer. Long-term efficacy and toxicity are reported after a median follow-up of 7.5 years.Methods. Patients with inoperable squamous cell carcinoma (SCC) of the oropharynx, oral cavity, or hypopharynx, were randomized between radiotherapy (RT) + IA cisplatin 150 mg/m(2), followed by systemic rescue or RT + I. V. cisplatin 100 mg/m(2). RT consisted of 46 Gy to the affected and elective areas, followed by a boost of 24 Gy.Results. Among 237 patients, 57 recurred locally, 35 regionally, and 80 locoregionally. There were 32 second primary tumors, 65 distant metastases, and 154 deaths. Locoregional control and overall survival were not different between the treatment arms. Late dysphagia was worse in the I.V. arm (log-rank p=.014).Conclusion. IA cisplatin did not improve tumor control compared to I.V. administered cisplatin, despite the higher dose in IA delivery of the drug. (C) 2015 Wiley Periodicals, Inc. Show less

Show moreBackground. Tumor volume is an important predictor of outcome in radiotherapy alone. Its significance in concomitant chemoradiation (CCRT) is much less clear. We analyzed the prognostic value of primary tumor volume for advanced head and neck squamous cell carcinoma (HNSCC) treated with CCRT.Methods. Three hundred sixty patients treated with definitive CCRT for advanced HNSCC were selected. The pretreatment MRI or CT scan was used to calculate the primary tumor volume. Median follow-up was 19.8 months.Results. The average primary tumor volume was 37.0 cm(3) (range, 2.1-182.7 cm(3); median, 28.7 cm(3)). Multivariate analysis showed a significant effect of tumor volume on local control. The hazard ratio for a local recurrence increased by 14% per 10 cm(3) volume increase (95% CI, 8% to 21%). There was no significant independent effect of T and N status on local control.Conclusion. For advanced HNSCC, tumor volume is more powerful for predicting outcome after CCRT than TNM status.
