Concomitant methotrexate and radiotherapy in advanced head and neck cancer: 15-year follow-up of a randomized clinical trial.

摘要

Long-term follow-up for patients who receive chemoradiation for head and neck cancer is lacking from most studies reported in the literature. This report gives a 15-year review of the use of concomitant methotrexate and radiation in advanced head and neck cancer. Although there has not been any significant benefit in overall survival, the primary control rate is higher in patients who received methotrexate in addition to radiotherapy. However, in those with oropharyngeal cancer, both primary control and survival were significantly improved when chemotherapy was used. The other most significant benefit from chemoradiation is the much lower rate of salvage operations for primary recurrence. The addition of methotrexate failed to show any effect on the development of metastatic neck nodes. The rate of block dissection of the neck was similar in both arms of the study and is comparable with the historical data collected at this institute. There has not been any significant increase in serious late morbidity. The timing of the methotrexate with radiotherapy has a significant influence on primary control and survival in head and neck cancer.
