Locally advanced inoperable pancreatic cancer (LAPC) has a poor prognosis. By increasing intensity of systemic therapy combined with an established safe chemoradiation technique, our intention was to enhance the outcomes of LAPC. In preparation for phase III evaluation, the feasibility and efficacy of our candidate regimen gemcitabine-oxaliplatin chemotherapy with sandwich 5-fluorouracil (5FU) and three-dimensional conformal radiotherapy (3DCRT) needs to be established.
A total of 48 patients with inoperable LAPC without metastases were given gemcitabine (1000 mg m(-2) d1 + d15 q28) and oxaliplatin (100 mg m(-2) d2 + d16 q28) in induction (one cycle) and consolidation (three cycles), and 5FU 200 mg m(-2) per day over 6 weeks during 3DCRT 54 Gy.
Median duration of sustained local control (LC) was 15.8 months, progression-free survival (PFS) was 11.0 months, and overall survival was 15.7 months. Survival rates for 1, 2, and 3 years were 70.2%, 21.3%, and 12.8%, respectively. Global quality of life did not significantly decline from baseline during treatment, which was associated with modest treatment-related toxicity.
Fixed-dose gemcitabine and oxaliplatin, combined with an effective and safe regimen of 5FU and 3DCRT radiotherapy, was feasible and reasonably tolerated. The observed improved duration of LC and PFS with more intensive therapy over previous trials may be due to patient selection, but suggest that further evaluation in phase III trials is warranted.
局部晚期不可切除的胰腺癌(LAPC)预后较差。通过增加系统治疗的强度并结合既定的安全放化疗技术,我们旨在提高 LAPC 的疗效。为了准备进行 III 期评估,需要确定我们候选方案吉西他滨-奥沙利铂化疗联合三明治式氟尿嘧啶(5FU)和三维适形放疗(3DCRT)的可行性和疗效。
共有 48 例无转移的不可切除 LAPC 患者接受吉西他滨(1000mg/m² d1+d15 q28)和奥沙利铂(100mg/m² d2+d16 q28)诱导治疗(一个周期)和巩固治疗(三个周期),以及在 54Gy 的 3DCRT 期间 6 周内每天给予 5FU 200mg/m²。
中位持续局部控制(LC)时间为 15.8 个月,无进展生存期(PFS)为 11.0 个月,总生存期(OS)为 15.7 个月。1、2、3 年生存率分别为 70.2%、21.3%和 12.8%。在治疗期间,全球生活质量没有从基线显著下降,这与适度的治疗相关毒性有关。
固定剂量的吉西他滨和奥沙利铂联合有效且安全的 5FU 和 3DCRT 放疗方案是可行的,且患者能够耐受。与以往试验相比,观察到更强化治疗的 LC 和 PFS 持续时间的改善可能是由于患者选择,但这表明需要在 III 期试验中进一步评估。
