PROBLEM TO BE SOLVED: To provide a means suppressing relapse and metastasis and further increasing the effect in radiotherapy of radiation resistant cancer except hypoxic state, by irradiating radiation in the presence of 1-(1-hydroxymethyl-2,3-dihydroxypropyl)oxymethyl-2-nitroimidazole. SOLUTION: In radiotherapy of cancer having radiation resistance, a radiation sensitizer of chemical formula 1 is used to sensitize and treat. The compound of chemical formula 1 of 10-400 mg is administered based on 1 kg body weight of animal or human and radiation is irradiated. The radiation resistant cancer is preferably lung adenocarcinoma. Fractionated irradiation therapy comprising administering 10-400 mg compound of formula 1 per 1 kg body weight to the animal or the human and then repeating 5-40 times irradiation of 1-10 Gy is preferable.
