[The outcomes of Tiantan first-aid protocol on critically ill patients with primary central nervous system lymphoma].

Objective: To examine the outcomes of Tiantan first-aid protocol on critically ill patients with primary central nervous system lymphoma (PCNSL). Methods: The clinical data of 18 patients with PCNSL who were treated according to Tiantan first-aid protocol at Department of Neurosurgery,Beijing Tiantan Hospital, Capital Medical University from November 2019 to December 2021 were retrospectively analyzed. There were 9 males and 9 females, aged (56.9±11.1)years (range: 29 to 77 years). The median Karnofsky performance status(KPS) score at admission was 40 (range: 20 to 60). Three patients were mild coma, 3 were lethargy and 12 were conscious. The mean midline shift was 0.7 cm (range: 0 to 1.8 cm). After admission, all patients were treated according to the plan of rapid biopsy, rapid routine pathology and rapid salvage chemotherapy. The treatment procedures, clinical and radiographic outcomes, KPS score and adverse reactions of patients after chemotherapy were collected. Results: All of the 18 patients completed the first-aid treatment. The median duration from admission to the biopsy was 1 day (range: 0 to 5 days), from biopsy to routine pathological diagnosis was 1 day (range: 1 to 4 days) and from routine pathology to salvage chemotherapy was 1 day (range: 0 to 4 days). All the patients were pathologically confirmed with diffuse large B cell lymphoma, 1 patient was double-hit lymphoma. Seventeen patients underwent clinical remission and 1 died of cardiac dysfunction. The successful salvage rate was 17/18. Radiologically, complete remission was observed in 1 case, partial remission in 16 cases, and stable disease in 1 case. The median KPS score at discharge was 60 (range: 30 to 80). The mild gastrointestinal, hematological and hepatic adverse effects were observed after chemotherapy. Conclusion: Tiantan first-aid protocol is effective for critically ill patients with PCNSL, which has the merit to be popularly used and improved.目的： 探讨急诊危重症原发性中枢神经系统淋巴瘤（PCNSL）患者的天坛医院急救方案的疗效。 方法： 回顾性分析2019年11月至2021年12月首都医科大学附属北京天坛医院神经外科收治的18例按天坛医院急救方案救治的危重症PCNSL患者的临床资料。男性9例，女性9例，年龄（56.9±11.1）岁（范围：29~77岁）。入院中位卡氏功能状态评分40分（范围：20~60分）；浅昏迷3例，嗜睡3例，清醒12例；脑中线平均偏移0.7 cm（范围：0~1.8 cm）。患者入院后均按快速活检、快速病理学诊断和快速抢救性化疗的方案进行救治。收集患者救治情况、化疗后临床和影像学缓解率、卡氏功能状态评分和不良反应情况。 结果： 18例患者均完成天坛医院急救方案救治，入院至活检的中位时间为1 d（范围：0~5 d），活检至常规病理学诊断的中位时间为1 d（范围：1~4 d），常规病理学诊断至化疗的中位时间为1 d（范围：0~4 d）。活检病理学诊断结果均为弥漫大B细胞淋巴瘤，其中1例为双打击淋巴瘤。化疗后临床好转17例，死亡1例（死因为心功能不全），抢救成功率为17/18；影像学疗效评估，肿瘤完全缓解1例，部分缓解16例，稳定1例。出院时，中位卡氏功能状态评分60分（范围：30~80分）。不良反应主要为胃肠道反应、血常规和肝功能异常。 结论： 应用天坛医院急救方案治疗PCNSL快速有效，值得进一步推行与改进。.
