Abstract

Immunotherapy has achieved unprecedented clinical efficacy in patients with various types of advanced tumors; however, some patients experience delayed tumor shrinkage following an increase in tumor burden after such a therapeutic method. This phenomenon is called pseudoprogression and can lead to premature cessation of efficacious immunotherapeutic agents. Consequently, we summarized the available data on methods to differentiate pseudoprogression from true progression in patients who have been treated with immunotherapy including biomarkers, medical imaging techniques and biopsy. We also introduce hyperprogression and special pseudoprogression for improved evaluation of immunotherapy.

摘要

免疫疗法在各类晚期肿瘤患者中取得了前所未有的临床疗效;然而,一些患者在接受这种治疗方法后,肿瘤负荷增加,随后出现肿瘤延迟缩小。这种现象被称为假性进展,可能导致有效免疫治疗药物过早停用。因此,我们总结了关于在接受免疫治疗的患者中区分假性进展与真性进展的方法的现有数据,包括生物标志物、医学成像技术和活检。我们还介绍了超进展和特殊假性进展,以改进对免疫治疗的评估。
