目的
2
探究化疗后重度骨髓抑制是否与乳腺癌患者的预后有关。
方法
2
以2013年5月2日至2018年5月2日在南昌大学第二附属医院接受化疗的三阴性乳腺癌(TNBC)患者为研究对象,分为对照组(无/轻度骨髓抑制)与病例组(重度骨髓抑制)。本研究符合纳入和排除标准的TNBC患者251例,其中对照组患者125例(0级骨髓抑制20例、Ⅰ级骨髓抑制43例、Ⅱ级骨髓抑制62例),病例组患者126例(Ⅲ级骨髓抑制114例、Ⅳ级骨髓抑制12例)。采用
χ
2
检验分析两组患者的一般临床病理资料,包括年龄、肿瘤病理类型、肿瘤T分期、肿瘤N分期、肿瘤Nottingham分级、脉管内癌栓、化疗方案,采用Kaplan-Meier法对两组患者的无病生存期(DFS)及总生存期(OS)进行分析,采用多因素Cox比例风险回归模型分析化疗后重度骨髓抑制对TNBC患者DFS及OS的影响。
结果
2
两组患者间的一般临床病理资料的差异均无统计学意义(
P
均>0.05)。对照组与病例组患者5年DFS率的差异具有统计学意义(75.2%
vs.
85.7%,
P
=0.027),5年OS率的差异无统计学意义(88.8%
vs.
95.2%,
P
=0.057)。多因素Cox比例风险回归模型分析显示,化疗后重度骨髓抑制是TNBC患者DFS(HR=0.332,95%CI:0.173~0.638,
P
=0.001)及OS(HR=0.193,95%CI:0.062~0.602,
P
=0.005)的独立保护因素。
结论
2
TNBC患者化疗后重度骨髓抑制患者的DFS较无/轻度骨髓抑制患者的长,OS亦有延长的趋势,化疗后重度骨髓抑制可作为乳腺癌预后良好的一个独立预测因子。
Objective
2
To investigate whether severe myelosuppression after chemotherapy is associated with prognosis in patients with breast cancer.
Methods
2
Triple negative breast cancer (TNBC) patients who received chemotherapy at the Second Affiliated Hospital of Nanchang University from May 2, 2013 to May 2, 2018 were divided into a control group (no/mild myelosuppression) and a case group (severe myelosuppression). In this study, 251 patients with TNBC met the inclusion and exclusion criteria, including 125 patients in the control group (20 patients with grade 0 myelosuppression, 43 patients with grade I myelosuppression, 62 patients with grade Ⅱ myelosuppression), 126 patients in the case group (114 patients with grade Ⅲ myelosuppression, 12 patients with grade Ⅳ myelosuppression). The general clinicopathological data of the patients in the two groups, including age, pathological type of tumor, tumor T stage, tumor N stage, tumor Nottingham grade, intravascular cancer thrombus, were analyzed using the
χ
2
test. The disease-free survival (DFS) and overall survival (OS) of the two groups were analyzed using the Kaplan-Meier method. A Cox proportional hazards regression model with multiple factors was used to analyze the impact of post-chemotherapy severe myelosuppression on disease-free survival (DFS) and overall survival (OS) in patients with TNBC.
Results
2
The differences in general clinicopathologic data between the two groups of patients were not statistically significant (all
P
>0.05). The 5-year disease-free survival (DFS) rate was significantly lower in the control group compared with the case group (75.2%
vs.
85.7%,
P
=0.027). However, there was no statistically significant difference in the 5-year overall survival (OS) rate between the two groups (88.8%
vs.
95.2%,
P
=0.057). The analysis of the multif
actorial Cox proportional hazards regression model revealed that post-chemotherapy severe myelosuppression was an independent protective factor for disease-free survival (DFS) (HR=0.332, 95% CI: 0.173-0.638,
P
=0.001) and overall survival (OS) (HR=0.193, 95% CI: 0.062-0.602,
P
=0.005) in TNBC patients.
Conclusion
2
Our results show that TNBC patients with severe myelosuppression after chemotherapy have longer disease-free survival (DFS) than those with no/mild myelosuppression, and overall survival (OS) also tend to be prolonged compared with those with no/mild myelosuppression, and severe myelosuppression after chemotherapy can be used as an independent predictor of a good prognosis in breast cancer.
