摘要

背景ctc对lt后肿瘤复发的预后价值研究尚不充分，ctc与免疫抑制剂之间的关系尚不清楚。方法对277例肝移植患者进行分析。从手术当日至术后1个月测量MCTC和ECTC水平。比较不同MCTC水平患者的预后结果，并根据是否存在主要门静脉肿瘤血栓进行亚组分析。进一步评估不同免疫抑制剂方案中MCTC动态和结果的差异。结果低MCTC患者的无复发生存率（RFS）高于高MCTC患者（p = 0.022）， PVTT亚组（p = 0.023）和非PVTT亚组（p = 0.046）均有此趋势。与未降低MCTC水平的患者相比，第二次测量时MCTC水平降低的患者预后明显更好（p = 0.03）。西罗莫司的使用与MCTC水平的降低相关（p = 0.017），与未使用西罗莫司的患者相比，接受西罗莫司的患者表现出更高的生存率（p = 0.033）。西罗莫司也延长了复发后生存期（p = 0.0052）。结论mctc水平可作为肝癌肝移植术后肿瘤复发的有效预测指标。西罗莫司降低MCTC水平，延长复发后生存期。

Mesenchymal circulating tumor cells as prognostic markers in HCC Post-Transplantation: Sirolimus as a potential therapeutic Modulator

Background

The prognostic value of CTCs for post-LT tumor recurrence remains insufficiently studied, and the associations between CTCs and immunosuppressants remain unclear.

Methods

This study analyzed 277 HCC patients undergoing liver transplantation. MCTC and ECTC levels were measured from the day of surgery to one month postoperatively. Prognostic outcomes were compared across patients with varying MCTC levels, with subgroup analysis based on the presence or absence of major portal vein tumor thrombus. Differences in MCTC dynamics and outcomes were further evaluated across immunosuppressant regimens.

Results

Patients with low MCTC levels demonstrated better recurrence-free survival (RFS) than those with high MCTC levels (p = 0.022), a trend observed in both the PVTT subgroup (p = 0.023) and the non-PVTT subgroup (p = 0.046). Patients with a reduction in MCTC levels at the second measurement had significantly better prognoses compared to those without a reduction (p = 0.03). The use of sirolimus was associated with a decrease in MCTC levels (p = 0.017), and patients receiving sirolimus exhibited improved survival compared to those not using sirolimus (p = 0.033). Sirolimus also extended post-recurrence survival (p = 0.0052).

Conclusion

MCTC levels serve as an effective predictor of tumor recurrence following liver transplantation for HCC. Sirolimus reduces MCTC levels and extends post-recurrence survival.
