BACKGROUND: Epidermal growth factor receptor (EGFR) is a new target for nasopharyngeal carcinoma (NPC) therapy. This prospective phase I study sought to determine the safety and recommended phase II dose of icotinib, a novel highly selective oral EGFR tyrosine kinase inhibitor, in combination with intensity-modulated radiotherapy (IMRT) in patients with NPC.

The aim of the present study was to explore the efficacy and mechanism of the radiosensitisation of icotinib hydrochloride (IH), a novel oral epidermal growth factor receptor-tyrosine kinase activity inhibitor, by evaluating the changes in tumour cell double-strand breaks (DSBs) repair, cell cycle and apoptosis following a combination of IH and radiotherapy (RT) in human colorectal adenocarcinoma cell lines. The HT29 and HCT116 human CRC cell lines were treated with IH and/or radiation. Effects on cell viability and cell cycle progression were measured by MTT, a clonogenic survival assay, and flow cytometry. Immunofluorescent staining and western blot analysis were applied to detect the expression of γ-H2AX and 53BP1 in the different treatment groups. Finally, the in vivo effect on the growth of CRC xenografts was assessed in athymic nude mice. IH inhibited the proliferation and enhanced the radiosensitivity in HT29 and HCT116 CRC cells lines.
