晚期卵巢癌初次减灭术前低白蛋白血症与生存:MSKCC Team Ovary研究
该回顾性研究纳入2015至2022年在本院接受初次减灭术的III-IV期上皮性卵巢癌患者636例,按术前血清白蛋白<3.5 g/dL分为低白蛋白组65例(10%)和正常白蛋白组571例(90%)。低白蛋白组与正常白蛋白组5年无进展生存率分别为18.3%与26.5%(P=0.107),5年总生存率分别为56.1%与66.1%(P=0.053),差异均无统计学意义;低白蛋白组完全肉眼切除率较低(66% vs 78%,P=0.029)。多因素分析中术前白蛋白并非独立预后因素,提示仅依据术前白蛋白水平可能将本可获益于初次减灭术的患者错误分配至新辅助化疗。
要点
- 低白蛋白组与正常白蛋白组5年PFS和OS差异均无统计学意义。
- 低白蛋白组完全肉眼切除率显著低于正常白蛋白组(66% vs 78%,P=0.029)。
- 术前白蛋白非总生存独立预后因素,不宜单独用于手术决策。
核心结论
- 低白蛋白血症与正常白蛋白患者的5年生存率相似。
- 仅依赖术前血清白蛋白水平选择新辅助化疗,可能使本可同等获益于初次减灭术的患者被错误分配。
研究设计与样本
- 回顾性研究,纳入2015年1月1日至2022年8月31日在本院接受初次减灭术的III-IV期上皮性卵巢癌患者636例。
- 按术前血清白蛋白<3.5 g/dL分为低白蛋白组65例(10%)和正常白蛋白组571例(90%)。
- 排除标准包括年龄≥80岁、75-79岁且体能状态差或复杂手术可能性高、第二恶性肿瘤及缺失术前白蛋白水平。
- 采用Kaplan-Meier法计算中位及5年无进展生存率和总生存率,分类变量用log-rank检验,连续变量用Wald检验。
主要发现
- 中位随访73个月(95% CI:68-76)。
- 低白蛋白组与正常白蛋白组5年无进展生存率分别为18.3%(95% CI:9.2%-29.9%)与26.5%(95% CI:22.6%-30.5%),P=0.107。
- 低白蛋白组与正常白蛋白组5年总生存率分别为56.1%(95% CI:41.5%-68.4%)与66.1%(95% CI:61.6%-70.3%),P=0.053。
- 低白蛋白组完全肉眼切除率为66%,正常白蛋白组为78%(P=0.029)。
- 总生存多因素分析中,年龄、组织学类型、BRCA状态和完全肉眼切除为显著预后因素,术前血清白蛋白不是。
关键数值与推荐
- 低白蛋白定义为术前血清白蛋白<3.5 g/dL,正常白蛋白定义为≥3.5 g/dL。
- 完全肉眼切除率低白蛋白组66% vs 正常白蛋白组78%(P=0.029)。
- 5年无进展生存率低白蛋白组18.3% vs 正常白蛋白组26.5%(P=0.107)。
- 5年总生存率低白蛋白组56.1% vs 正常白蛋白组66.1%(P=0.053)。
临床怎么用
- 术前血清白蛋白水平不宜单独作为晚期上皮性卵巢癌患者选择新辅助化疗而非初次减灭术的依据。
- 对低白蛋白血症患者应综合评估年龄、组织学类型、BRCA状态及预期完全肉眼切除可能性后再制定手术策略。
局限性
- 回顾性单中心研究设计。
- 低白蛋白组样本量较小(65例)。
- 存在选择偏倚可能,因排除标准排除了高龄及体能状态差的患者。

OBJECTIVE: To examine if preoperative serum albumin (SA) level is associated with worse survival following primary debulking surgery (PDS) for epithelial ovarian cancer (EOC). METHODS: In this retrospective study, we identified patients with stage III-IV EOC who underwent PDS at our institution from 1/1/2015-8/31/2022. Patients were assigned to the low albumin (LA; SA < 3.5 g/dL) or normal albumin (NA; SA ≥ 3.5 g/dL) group. Exclusion criteria included age ≥ 80 years, age 75-79 years with poor physical status or high likelihood of complex surgery, secondary malignancy, and missing preoperative SA level. Median and 5-year progression-free (PFS) and overall survival (OS) rates were calculated using Kaplan-Meier method. Log-rank test was used for categorical variables and Wald test for continuous variables. RESULTS: Overall, 636 patients were identified, 65 (10%) in the LA and 571 (90%) in the NA group. Median follow-up was 73 months (95% CI: 68-76). Comparing the LA versus NA group, 5-year PFS rate was 18.3% (95% CI: 9.2%-29.9%) vs 26.5% (95% CI: 22.6%-30.5%), respectively (P = 0.107); 5-year OS rate was 56.1% (95% CI: 41.5%-68.4%) vs 66.1% (95% CI: 61.6%-70.3%), respectively (P = 0.053). Complete gross resection (CGR) was achieved in 66% of patients with LA compared to 78% with NA (P = 0.029). On multivariate analysis of OS, age, histology, BRCA status, and CGR were statistically significant prognostic factors, but preoperative SA was not. CONCLUSIONS: Five-year survival rates were similar between patients with and without hypoalbuminemia. Relying on preoperative SA level alone, patients may be selected for neoadjuvant chemotherapy who would have equivalent survival outcomes with PDS.
