Abstract

Background: Major hepatectomy (MH) can increase the risk of adverse events (AEs) owing to impaired drug metabolism due to decreased liver volume and surgical injury. Thus, we performed this subgroup analysis using data from JCOG1113, a phase III trial comparing gemcitabine plus S-1 (GS) and gemcitabine plus cisplatin (GC) in patients with advanced and recurrent biliary tract cancer (BTC), to evaluate the effect of MH on the safety and efficacy of GC and GS regimens in patients with recurrent BTC.

Methods: Of the 354 patients with advanced BTC enrolled in JCOG1113, 76 patients with postoperative recurrence (30 in the MH group and 46 in the non-MH group) were analyzed.

Results: Grade ≥ 3 platelet count decreased in both arms was more frequent in the MH group than in non-MH group (GC, 0.0 vs. 17.6%; GS, 3.9 vs. 15.4%). However, in the MH group, the white blood cell decreased (GC, 55.0 vs. 38.5%; GS, 23.1 vs. 7.7%) and anemia (GC, 15.0 vs. 11.8%; GS, 23.1 vs. 7.7%) were less common than in the non-MH group. The MH and non-MH groups showed no significant difference in overall survival (OS) in both GC [median OS, 23.0 in MH vs. 16.9 months in non-MH (hazard ratio, 0.857; 95% CI 0.387-1.899)], and GS [median OS, 21.5 vs. 14.9 months (hazard ratio, 0.670; 95% CI 0.310-1.447)] arms.

Conclusions: The safety and efficacy of gemcitabine-based chemotherapy were comparable between patients who underwent MH and those who underwent other surgeries.

肝切除术对术后复发胆管癌吉西他滨化疗的影响：JCOG1113亚组分析。

背景：大肝切除术（MH）会增加不良事件（AEs）的风险，因为肝脏体积缩小和手术损伤会导致药物代谢受损。因此，我们利用吉西他滨加 S-1（GS）和吉西他滨加顺铂（GC）治疗晚期和复发性胆道癌（BTC）患者的 III 期试验 JCOG1113 的数据进行了亚组分析，以评估 MH 对复发性 BTC 患者中 GC 和 GS 方案的安全性和有效性的影响：方法：在参加 JCOG1113 的 354 例晚期 BTC 患者中，分析了 76 例术后复发患者（MH 组 30 例，非 MH 组 46 例）：两组患者血小板计数≥3级的情况在MH组均多于非MH组（GC，0.0 vs. 17.6%；GS，3.9 vs. 15.4%）。然而，在 MH 组，白细胞减少（GC，55.0 vs. 38.5%；GS，23.1 vs. 7.7%）和贫血（GC，15.0 vs. 11.8%；GS，23.1 vs. 7.7%）的发生率低于非 MH 组。在总生存期（OS）方面，MH组和非MH组在GC[MH组中位OS为23.0个月，非MH组为16.9个月（危险比为0.857；95% CI为0.387-1.899）]和GS[MH组中位OS为21.5个月，GS组为14.9个月（危险比为0.670；95% CI为0.310-1.447）]两组中均无明显差异：结论：接受MH手术和其他手术的患者接受以吉西他滨为基础的化疗的安全性和有效性相当。

期刊介绍： The International Journal of Clinical Oncology (IJCO) welcomes original research papers on all aspects of clinical oncology that report the results of novel and timely investigations. Reports on clinical trials are encouraged. Experimental studies will also be accepted if they have obvious relevance to clinical oncology. Membership in the Japan Society of Clinical Oncology is not a prerequisite for submission to the journal. Papers are received on the understanding that: their contents have not been published in whole or in part elsewhere; that they are subject to peer review by at least two referees and the Editors, and to editorial revision of the language and contents; and that the Editors are responsible for their acceptance, rejection, and order of publication.
