Most patients with chemotherapy-induced febrile neutropenia recover rapidly without serious complications. However, it still remains a life-threatening treatment-related toxicity, and is associated with dose reductions and delays of chemotherapeutic agents that may compromise treatment outcomes. Recent developments of risk stratification enabled early discharge with oral antibiotics for low-risk patients. However, even in low-risk patients, medical complications including bacteremia could happen. The authors reviewed recent literature to provide an update on research regarding predictive factors for poor prognosis in patients with febrile neutropenia.
Various prognostic factors have been suggested with controversies. Hematological parameters, prophylactic measurements and patient-specific risk factors showed inconsistent results. MASCC risk-index score, which was originally developed to identify low-risk patients, in turn showed that the lower the MASCC score, the poorer the prognosis of febrile neutropenia, with very low levels (<15), the rate of complications was high. Patients with severe sepsis and septic shock commonly had procalcitonin concentration above 2.0 ng/ml, and this level should be considered at high risk of poor prognosis.
Lower MASCC score and higher procalcitonin concentration can predict poor outcomes in febrile neutropenia. More research is required with regard to the other factors showing controversies.
大多数化疗引起的发热性中性粒细胞减少症患者可迅速康复,无严重并发症。然而,它仍然是一种危及生命的治疗相关毒性,与减少剂量和延迟化疗药物有关,这可能会影响治疗效果。最近的风险分层发展使低危患者能够用口服抗生素提前出院。然而,即使在低危患者中,也可能发生包括菌血症在内的医疗并发症。作者回顾了最近的文献,提供了关于发热性中性粒细胞减少症患者不良预后预测因素的研究更新。
已经提出了各种预后因素,但存在争议。血液学参数、预防措施和患者特定的危险因素显示出不一致的结果。最初开发用于识别低危患者的 MASCC 风险指数评分,反过来表明 MASCC 评分越低,发热性中性粒细胞减少症的预后越差,评分非常低(<15)时,并发症发生率很高。严重脓毒症和感染性休克患者的降钙素原浓度通常高于 2.0ng/ml,应考虑该水平存在预后不良的高风险。
较低的 MASCC 评分和较高的降钙素原浓度可以预测发热性中性粒细胞减少症的不良预后。需要对其他存在争议的因素进行更多研究。
