Patients undergoing first-line chemotherapy after diagnosis of lymphoma have considerable DNA damage in their peripheral blood lymphocytes, using sister chromatid exchange (SCE) frequency as a sensitive indicator. Different drug regimens produce different patterns of changes in SCE frequency. These may be related to their potential to induce second malignancies.
以姐妹染色单体交换(SCE)频率作为敏感指标,淋巴瘤诊断后接受一线化疗的患者外周血淋巴细胞存在大量DNA损伤。不同的药物方案会使SCE频率产生不同的变化模式。这些可能与其诱发第二原发性恶性肿瘤的可能性有关。
