Background: The combination of gemcitabine and dacarbazine has exhibited efficacy in terms of progression-free survival (PFS) and overall survival (OS) for aSTSs, albeit without robust confirmation from larger clinical trials. Methods: We conducted a retrospective study in a single institution involving aSTS patients treated with gemcitabine and dacarbazine. Results: 95 patients were assessed, pointing to a benefit in PFS of 3.5 months and an OS of 14.2 months. Patients with translocated histotypes had better PFS, while those with platelet–lymphocyte ratios (PLRs) surpassing a specific threshold or lower albumin levels had poorer overall survival. Conclusions: This study validates previous findings from three phase I–II trials, affirming the utility of this treatment approach in routine clinical practice.
背景:吉西他滨与达卡巴嗪联合用药方案在延长晚期软组织肉瘤(aSTSs)患者的无进展生存期(PFS)和总生存期(OS)方面已显示出疗效,但尚未通过大规模临床试验获得有力证实。方法:我们在单一机构开展了一项回顾性研究,纳入接受吉西他滨联合达卡巴嗪治疗的晚期软组织肉瘤患者。结果:共评估95例患者,其PFS获益达3.5个月,OS达14.2个月。具有易位组织学亚型的患者PFS更优,而血小板-淋巴细胞比值(PLR)超过特定阈值或白蛋白水平较低的患者总生存期较差。结论:本研究验证了此前三项I-II期临床试验的结果,证实了该治疗方案在常规临床实践中的应用价值。
