The effect of high-dose pyridoxine (PN) on activity of 5-fluorouracil (FUra) and folinic acid (FA)-containing regimens was studied in 50 patients including 14 with digestive tract, and 36 with breast carcinomas (BC) in advanced stages with poor prognostic characteristics. Patients with colorectal, and pancreas adenocarcinoma received oxaliplatin, irinotecan, FUra, FA (Folfirinox), and patients with squamous cell carcinoma of the esophagus had paclitaxel, carboplatin, FUra, FA (TCbF). Patients with BC received AVCF (doxorubicin, vinorelbine, cyclophosphamide, FUra, FA) followed by TCbF or TCbF only, and patients who overexpressed HER2 received TCbF plus trastuzumab and pertuzumab. PN (1000-3000 mg/day iv) preceded each administration of FUra and FA. 47 patients (94%) responded, including 16 (32%) with CR. Median tumor reduction was 93%. Median event-free survival (EFS) was 37.7 months. The 25 patients with tumor shrinkage ≥ 91% had EFS of 52% from 42 months onwards. Unexpected toxicity did not occur. PN enhances potency of chemotherapy regimens comprising FUra and FA.
研究了大剂量吡哆醇(PN)对含 5-氟尿嘧啶(FUra)和甲酰四氢叶酸(FA)的方案在 50 例患者中的作用,包括 14 例消化系统和 36 例晚期乳腺癌(BC)患者,这些患者具有不良预后特征。结直肠癌和胰腺腺癌患者接受奥沙利铂、伊立替康、FUra、FA(Folfirinox)治疗,食管鳞状细胞癌患者接受紫杉醇、卡铂、FUra、FA(TCbF)治疗。BC 患者接受 AVCF(阿霉素、长春瑞滨、环磷酰胺、FUra、FA)治疗,然后接受 TCbF 或仅 TCbF 治疗,HER2 过表达的患者接受 TCbF 加曲妥珠单抗和帕妥珠单抗治疗。PN(1000-3000mg/天静脉注射)在每个 FUra 和 FA 给药前给予。47 例(94%)患者有反应,包括 16 例(32%)完全缓解。肿瘤缩小中位数为 93%。中位无进展生存期(EFS)为 37.7 个月。25 例肿瘤缩小≥91%的患者,EFS 从 42 个月开始为 52%。未发生意外毒性。PN 增强了包含 FUra 和 FA 的化疗方案的效力。
