Randomized Controlled Trial Comparative Study
Docetaxel, cisplatin and 5-fluorouracil induction chemotherapy followed by chemoradiotherapy or chemoradiotherapy alone in stage III-IV unresectable head and neck cancer: Results of a randomized phase II study.
Concurrent chemoradiotherapy (CRT) is the standard treatment for advanced head and neck squamous cell carcinoma. In this phase II randomized study, the efficacy and toxicity of docetaxel, cisplatin and 5-fluorouracil induction chemotherapy (ICT) followed by concurrent CRT was compared with those after standard CRT alone in patients with locally advanced, unresectable head and neck cancer. ⋯ The addition of ICT to CRT did not show any advantage in our phase II trial, while the incidence of adverse events increased. The three deaths as a consequence of ICT call attention to the importance of adequate patient selection if ICT is considered.

Radiotherapy has been reported to promote the invasion of glioblastoma cells; however, the underlying mechanisms remain unclear. Here, we investigated the role of the Wnt/β-catenin pathway in radiation-induced invasion of glioblastoma cells. ⋯ Our data demonstrate a pivotal role of the Wnt/β-catenin pathway in ionizing radiation-induced invasion of glioblastoma cells, and suggest that targeting β-catenin is a promising therapeutic approach to overcoming glioma radioresistance.
