医源性癌临床上指由于治疗疾病而诱发的癌瘤,其病因仍在继续探讨阶段,文献报道以放射治疗后,于放射野内出现另一个不同病理类型的恶性肿瘤最为多见,其他如采用类固醇激素、抗癌化学药物以及某些造影剂后均可能诱发本病。 Goolden(1957)指出,头颈部肿瘤,不论良性和恶性,经放射治疗后发生医源性诱发癌的特点是:(1)诱发癌发生时间一般要隔数年之久;(2)诱发癌的病理分型与原发癌非同一类型;(3)诱发癌必须位于X线照射区域以内,
Iatrogenic cancer is clinically referred to as a cancerous tumor induced by the treatment of disease. The etiology of the disease is still being explored. After the radiotherapy is reported in the literature, another malignant tumor with different pathological types appears in the radiation field. Steroid hormones, anticancer chemicals, and certain contrast agents can all induce the disease. Goolden (1957) pointed out that head and neck tumors, benign and malignant, are characterized by iatrogenic induced cancer after radiotherapy: (1) the time of induction of cancer is generally several years apart; (2) the induction of cancer The pathological type is not the same as the primary cancer; (3) The induced cancer must be located within the X-ray exposure area.
