研究概览
详细说明
研究的材料和方法。 根据哈萨克斯坦国立医科大学地方伦理委员会的批准,该研究计划纳入来自哈萨克斯坦19个地区的200名患者,这些患者经组织学证实诊断为“结直肠癌”,并在哈萨克斯坦4个地区的肿瘤中心接受治疗。哈萨克斯坦,那里有大学诊所。
按治疗类型划分的结直肠癌患者 (CRC) 分布。
- 主要组 - 根据 FOLFOX 方案化疗联合核酸钠 100
- 对照组 根据 FOLFOX 方案进行化疗 100 研究设计 该研究设计包括评估 FOLFOX 化疗联合核酸钠免疫治疗对 187 名 T3-4 N1-2 M1 期转移性结直肠癌患者的有效性。 使用包络法随机分为两组(主组和对照组)。
主要组包括89例转移性结直肠癌(T3-4 N1-2 M期)患者,接受4个疗程的FOLFOX化疗联合核酸钠线粒体免疫治疗。 医疗康复方案包括每天服用 50 毫克核酸钠:早上 25 毫克,午餐前 25 毫克,每天服用,持续四个月。
对照组由 98 名转移性结直肠癌(T3-4 N1-2 M 期)患者组成,仅接受 4 个疗程的 FOLFOX 化疗。 在两组中,每月进行一般和生化血液分析。
另外,治疗开始前及治疗结束后1个月进行PET-CT扫描,测定肿瘤标志物CEA、CA-19-9水平,评估CD4/CD8免疫状态和中性粒细胞线粒体活性,并进行超声心动图测定左心室射血分数。 还进行了一份健康调查问卷(欧洲癌症研究与治疗组织 (EORTC) QLQ-CR29)。
关键点
- 减少转移性结直肠癌 (CRC) 化疗期间因白细胞减少症、中性粒细胞减少症和感染并发症导致的治疗中断。
- 结直肠癌姑息化疗期间肿瘤过程稳定的百分比增加。
转移性结直肠癌姑息治疗期间一年死亡率降低。 使用Windows应用程序包“Statistica 7.0”(StatSoft,美国)对研究结果进行统计分析。 曼-惠特尼 U 准则用于通过定性指标来比较研究样本。

Relative Dose Intensity of FOLFOX
大体时间:1-4 cycles of FOLFOX
|
Relative Dose Intensity (RDI) over cycles 1-4 of FOLFOX, calculated as (delivered dose intensity / planned dose intensity) × 100.
Dose intensity accounts for both dose reductions and treatment delays for oxaliplatin (mg/m²/week) and infusional 5-fluorouracil (mg/m²/week).

EORTC QLQ-C30 Global Health Status/QoL (GHS/QoL)
大体时间:Baseline (before start of chemotherapy); 1 month after completion of 4 cycles (approximately 5 months after baseline); 1 year post-baseline
|
Global health status/quality of life subscale from the EORTC QLQ-C30.
Scores are linearly transformed to a 0-100 scale.
Higher scores indicate better global health status/quality of life (better outcome).
Minimum = 0, maximum = 100.
This is a subscale score, not a total scale score.
|
Baseline (before start of chemotherapy); 1 month after completion of 4 cycles (approximately 5 months after baseline); 1 year post-baseline
|
|
Mitochondrial Activity of Neutrophils
大体时间:Baseline (before start of chemotherapy) and post-treatment assessment 1 month after completion of chemotherapy
|
Mitochondrial activity of neutrophils assessed in peripheral blood as the percentage (%) of neutrophils with preserved mitochondrial function among 200 counted neutrophils per participant.
Range 0-100%.
Higher percentages indicate better preserved neutrophil mitochondrial function.
Primary metric: change from baseline to 1 month after completion of chemotherapy.
|
Baseline (before start of chemotherapy) and post-treatment assessment 1 month after completion of chemotherapy
|
|
Positron Emission Tomography/Computed Tomography (PET/CT) Tumour Metabolic Activity
大体时间:Baseline (before start of chemotherapy) and follow-up FDG-PET/CT 1 month after completion of chemotherapy (approximately 5 months after baseline).
|
Metabolic response to treatment assessed by [18F]FDG PET/CT using EORTC PET response criteria based on the change in tumor FDG uptake (e.g., SUV metric) between baseline and follow-up.
Participants were classified into mutually exclusive categories: partial metabolic response (PMR) (≥25% decrease in tumor FDG uptake), stable metabolic disease (SMD) (does not meet PMR or PMD), or progressive metabolic disease (PMD) (≥25% increase in tumor FDG uptake and/or new FDG-avid lesions).
Higher metabolic activity and PMD indicate worse disease activity.
|
Baseline (before start of chemotherapy) and follow-up FDG-PET/CT 1 month after completion of chemotherapy (approximately 5 months after baseline).
|
|
CEA Response (≥50% Decrease From Baseline)
大体时间:Baseline (before start of chemotherapy) and 1 month after completion of chemotherapy (approximately 5 months after baseline)
|
Serum CEA concentration measured in peripheral blood and reported in ng/mL.
Higher CEA values generally indicate higher tumor burden and are used to monitor treatment response in conjunction with imaging.
CEA response defined as a ≥50% decrease in serum CEA concentration from baseline to 1 month after completion of chemotherapy.
|
Baseline (before start of chemotherapy) and 1 month after completion of chemotherapy (approximately 5 months after baseline)
|
|
CA 19-9(Carbohydrate Antigen 19-9) Response (≥50% Decrease From Baseline)
大体时间:Baseline (before start of chemotherapy) and 1 month after completion of chemotherapy (approximately 5 months after baseline)
|
CA 19-9 response defined as a ≥50% decrease in serum CA 19-9 concentration from baseline to 1 month after completion of chemotherapy.
CA 19-9 measured in U/mL.
Higher CA 19-9 values indicate higher tumor burden (worse outcome).
Normal range approximately 0-27 U/mL.
|
Baseline (before start of chemotherapy) and 1 month after completion of chemotherapy (approximately 5 months after baseline)
|
|
CD4+/CD8+ T-Cell Ratio (Peripheral Blood)
大体时间:Baseline (before start of chemotherapy) and 1 month after completion of chemotherapy (approximately 5 months after baseline)
|
CD4+/CD8+ T-cell ratio measured in peripheral blood (unitless ratio).
The prespecified metric is the change in CD4+/CD8+ ratio from baseline to 1 month after completion of chemotherapy.
|
Baseline (before start of chemotherapy) and 1 month after completion of chemotherapy (approximately 5 months after baseline)
|
|
Left Ventricular Ejection Fraction (LVEF) by Echocardiography
大体时间:baseline (before start of chemotherapy)
|
Left ventricular ejection fraction (LVEF) ≥50% by echocardiography at baseline was required for study inclusion.
Patients with LVEF <50% were excluded.
