项目摘要

From the present project, the following results were obtained.1.Initially, we evaluated radiation sensitivity in the nude mice transplanted with human bladder cancer cell lines. Utilizing this model, we set up the radiation exposure condition (single time irradiation of 5 Gy) and confirmed that tumor growth delayd reaction could be evaluated as an endpoint of radiation sensitivity.2.The establishment of Xenogarft model : Tumor growth was observed in 18 mice (60%, 18/30). Histologically, 15 of the18 were epithelial carcinomas similar to the original tumors, resulting in a 50% (15/30) take rate. No correlation was found between the tumor take rate and the clinicopathologic features, TP53 mutational status, or Ki67 LI of the patients' tumors. Of the 15 xenografts, 11 xenografts were passed from 3 to 10 generations. TP53 mutational status remained stable during the passages, though the Ki67 LI slightly increased in the majority of xenografts. Specific growth delay after irradiation in the 4 xenografts was observed independent of the original tumor growth speed and Ki67 LI.3.Radiological growth delay assay : To assess the usefulness of these xenografts for therapeutic simulation, we performed radiological growth-delay assay in 4 xenografts and examined the relation between the responses and the biological parameters of xenograft tumors. The radiation response considerably varied among the 4 models. Absolute growth delay ranged from 20.3+2.4 (mean+standard error) to 76.4±7.4 days. Specific growth delay (SGD) was not associated with in vivo tumor growth speed or the Ki67 Il. The smallest SGD value was observed in the No.3 model which harbored TP53 gene mutation.
本项目获得了以下结果:1.首先,我们评估了移植人膀胱癌细胞系的裸鼠的放射敏感性。利用该模型,我们建立了辐射暴露条件(单次照射5 Gy),并证实肿瘤生长延迟反应可以作为辐射敏感性终点进行评估。2.Xenogarft模型的建立:在18只小鼠(60%,18/30)中观察到肿瘤生长。组织学上,18 个中的 15 个是与原始肿瘤相似的上皮癌,导致合格率为 50%(15/30)。肿瘤发生率与患者肿瘤的临床病理特征、TP53突变状态或Ki67 LI之间没有发现相关性。在15个异种移植物中,11个异种移植物从3代传到10代。尽管 Ki67 LI 在大多数异种移植物中略有增加,但 TP53 突变状态在传代过程中保持稳定。在 4 个异种移植物中观察到辐射后的特定生长延迟,与原始肿瘤生长速度和 Ki67 LI 无关。3.放射学生长延迟测定:为了评估这些异种移植物在治疗模拟中的有用性,我们在 4 个异种移植物中进行放射学生长延迟测定,并检查异种移植肿瘤的反应与生物学参数之间的关系。 4 种型号的辐射响应差异很大。绝对生长延迟范围为 20.3+2.4(平均值+标准误差)至 76.4±7.4 天。特定生长延迟(SGD)与体内肿瘤生长速度或Ki67 II无关。在TP53基因突变的No.3模型中观察到最小的SGD值。
