Abstract:

Background

The mFOLFIRINOX regimen(oxaliplatin, irinotecan, leucovorin and 5-fluorouracil) and GX regimen (gemcitabine combined with capecitabine) are standard adjuvant chemotherapies for resected pancreatic ductal adenocarcinoma(PDAC), but mFOLFIRINOX exhibits significant toxicities. SOXIRI regimen(S-1 combined with oxaliplatin and irinotecan) and GS regimen(gemcitabine plus S-1) are used as modified on the basis of mFOLFIRINOX and GX regimen. The comparison of GS and SOXIRI has not been reported.

Objective

To compare the efficacy and safety of adjuvant GS with SOXIRI for PDAC retrospectively.

Methods

This study analyzed 41 patients with PDAC who underwent postoperative adjuvant chemotherapy at the Oncology Center of Nanjing Drum Tower Hospital, Affiliated Hospital of Nanjing University Medical School, from March 2018 to June 2023(21 in the GS group and 20 in the SOXIRI group). The enrolled patients were followed up via review of electronic medical records and telephone calls. The follow-up period continued until August 31, 2024. The primary endpoint was disease-free survival (DFS). Secondary endpoints included the 2-year overall survival (OS) rate and adverse events (AEs). Survival curves were plotted using the Kaplan-Meier method and compared with the Log-rank test. Univariate and multivariate Cox proportional hazards models were used to identify factors associated with DFS and OS.

Results

The median disease-free survival (mDFS) was 18.65 months in the GS group and 13.03 months in the SOXIRI group, with the 2-year overall survival (OS) rates being 84.7% and 66.0%, respectively. No statistically significant differences were observed in mDFS and 2-year OS rates between the two groups (χ2=0.646, P=0.421; χ2=3.269, P=0.071). Multivariate Cox proportional hazards regression analysis revealed that postoperative CA19-9 level (HR=3.66, 95%CI=1.26-10.64) and surgical margin status (HR=2.64, 95%CI=1.05-6.61) were independent influence factors for DFS (P<0.05), whereas advanced age (HR=3.42, 95%CI=1.13-10.36) and TNM stage (HR=5.68, 95%CI=1.40-22.97) were independent influnce factors for OS (P<0.05). Subgroup analysis showed no statistically significant difference in therapeutic efficacy between the GS and SOXIRI regimens (P>0.05). The incidences of overall diarrhea (χ2=7.796, P=0.005) and peripheral neurotoxicity (χ2=7.552, P=0.006) were significantly higher in the SOXIRI group than in the GS group.

Conclusion

For postoperative adjuvant therapy in PDAC, the GS demonstrated noninferiority to the SOXIRI regimen in efficacy and better safety with lower diarrhea/peripheral nerve toxicity incidence.

摘要:

背景

改良的奥沙利铂+伊立替康+亚叶酸钙+氟尿嘧啶(mFOLFIRINOX)方案与吉西他滨+卡培他滨(GX)方案是胰腺导管腺癌(PDAC)切除术后的标准辅助化疗方案,但mFOLFIRINOX方案存在显著毒性。替吉奥+奥沙利铂+伊利替康(SOXIRI)方案和吉西他滨+替吉奥(GS)方案分别为上述方案的改良方案。目前GS与SOXIRI方案的直接比较研究尚少。

目的

比较GS与SOXIRI辅助化疗方案治疗PDAC的疗效与安全性。

方法

纳入2018年3月—2023年6月于南京大学医学院附属鼓楼医院肿瘤中心接受胰腺导管腺癌术后辅助化疗的41例患者为研究对象,其中接受GS方案治疗的患者21例(GS组),接受SOXIRI方案治疗的患者20例(SOXIRI组),通过查阅电子病历及电话等方式对入组患者进行随访,随访截至2024-08-31。主要观察终点为无病生存期(DFS),次要终点包括2年总生存期(OS)率及不良事件(AEs)。采用Kaplan-Meier法绘制两组患者的DFS和OS生存曲线,采用Log-rank检验对两条生存曲线的差异进行统计学比较。采用单因素和多因素Cox比例风险回归分析影响DFS和OS的相关因素。

结果

GS组与SOXIRI组的中位无病生存期(mDFS)分别为18.65个月和13.03个月,2年OS率分别为84.7%和66.0%,两组mDFS和2年OS率比较,差异均无统计学意义(χ2=0.646,P=0.421;χ2=3.269,P=0.071)。多因素Cox比例风险回归分析显示,术后糖类抗原19-9(CA19-9)水平(HR=3.66,95%CI=1.26~10.64)及切缘状态(HR=2.64,95%CI=1.05~6.61)是DFS的独立影响因素(P<0.05),而高龄(HR=3.42,95%CI=1.13~10.36)与TNM分期(HR=5.68,95%CI=1.40~22.97)是OS的独立影响因素(P<0.05)。亚组分析显示,GS方案与SOXIRI方案治疗疗效比较,差异均无统计学意义(P>0.05)。SOXIRI组的总体腹泻(χ2=7.796,P=0.005)和周围神经毒性(χ2=7.552,P=0.006)发生率高于GS组。

结论

在PDAC术后辅助化疗中,GS方案在疗效上不劣于SOXIRI方案,且安全性更佳,腹泻与周围神经毒性发生率更低。
