lign:justify;"> Objective: So as to provide a theoretical basis for the future development of intervention measures to reduce the negative psychological mood of caregivers. To investigate the psychological status of the main caregivers for patients who were transferred out of ICU after craniocerebral tumor surgery and analyze their factors. Methods: 112 patients with cerebral tumor surgery were reviewed from sun yat-sen university cancer hospital. The research object is caregivers. The general data questionnaire, hospital anxiety depression scale and migration of ICU patients’ family members stress questionnaire scale investigation are collected. Multiple linear regression analysis in cerebral tumor patients with postoperative ICU transition out main factors influencing the psychological condition of the caregivers. Results: The anxiety and depression scores were (15.60 ± 5.83) and (38.73 ± 3.23) respectively. The results of multiple regression analysis showed that the gender, education level, relationship with the patient and family monthly income of the primary caregivers of the patients were the influencing factors of anxiety, depression and migration stress psychological state (P Conclusion: The main caregivers of patients who were transferred out of ICU after craniocerebral tumor surgery had relatively severe anxiety, depression and migration stress. Medical staff should pay attention to the psychological status of caregivers and take effective measures to promote their physical and mental health.

嵌合抗原受体T细胞(chimeric antigen receptor T cells,CAR-T)疗法在血液系统肿瘤治疗中已展示出卓越成效。BCMA抗原在骨髓瘤细胞表面普遍表达,是合适高效的CAR-T治疗靶抗原。尤其是对于复发/难治性多发性骨髓瘤患者,BCMA CAR-T细胞治疗缓解率高,多数患者在输注1年后仍可在体内检测到CAR-T细胞。但是耐药与疾病复发仍是目前临床管理中面对的关键问题。本文将从多发性骨髓瘤细胞免疫逃逸、CAR-T产品因素、既往治疗方案及肿瘤免疫微环境的抑制等几个方面来探讨BCMA CAR-T细胞疗法的应答响应因素及耐药诱导机制,并提出可能的优化策略,以期为未来探索提供参考意义。
