摘要:

文题释义:
高分子纳米粒子:大小通常在1-1 000 nm之间,一般由天然高分子或合成高分子构成,可作为药物传递的载体,从而提高疗效、降低毒副作用。
骨肉瘤:最常见的恶性骨肿瘤之一,由间质细胞系发展而来,好发于儿童和青少年,特点是肿瘤经软骨阶段直接或间接形成肿瘤骨样组织。

背景:近年来研究者开发了各种高分子纳米粒子作为抗肿瘤药物载体,并利用纳米粒子的优势,例如血液循环时间延长、肿瘤内选择性聚集等,提高对骨肉瘤的疗效。

目的:基于最新的相关研究,对高分子纳米药物在骨肉瘤治疗方面的应用及其发展前景作以综述。

方法:作者应用计算机检索Web of Science、NCBI和PubMed生物医学数据库,检索时间为1900年至2019年6月,以“osteosarcoma;polymer;nanoparticle;controlled drug delivery;tumor therapy”为检索关键词,初检文章265篇,筛选后将107篇文章纳入高分子纳米药物治疗骨肉瘤的相关研究报道。

结果与结论:骨肉瘤是最常见的恶性骨肿瘤,主要影响儿童和青少年,早期远处肺转移和局部高侵袭性使骨肉瘤患者长期生存率降低。虽然化疗提高了骨肉瘤患者的生存率,但其应用潜力因严重不良反应和耐药性受到限制。与传统化疗相比,高分子纳米药物不仅降低了对正常组织的毒副作用,而且还能够延长体内循环时间,使化疗药物在肿瘤部位持续缓慢释放,从而提高了治疗效果。因此高分子纳米药物对于骨肉瘤的治疗具有巨大的应用前景。

Abstract:

BACKGROUND: In recent years, various polymer nanoparticles have been developed as anticancer drug carriers to prolong blood circulation time and improve intratumoral accumulation, and then enhance the therapeutic efficacy on osteosarcoma.

OBJECTIVE: To review the application and development of polymer nanomedicines for treatment of osteosarcoma based on latest related studies.

METHODS: A computer-based online search of Web of Science, NCBI, and PubMed was performed to search publications published between January 1900 and June 2019 with the search terms “osteosarcoma; polymer; nanoparticle; controlled drug delivery; tumor therapy". A total of 265 publications were screened out, and 107 of them regarding polymer nanoparticles for treatment of osteosarcoma were included in the final analysis.

RESULTS AND CONCLUSION: Osteosarcoma is the most common primary malignant bone tumor, mainly affecting children and adolescents. The long-term survival rate of osteosarcoma patients is low due to early lung metastasis and high local invasiveness. Although chemotherapy increases the survival rates of patients with osteosarcoma, its application potential is limited by severe side effects and drug resistance. Compared with traditional chemotherapy, polymer nanomedicines reduce the toxicity to healthy tissues, prolong the blood circulation time in vivo, and provide continuous release of chemotherapy drugs at the tumor sites, thereby improving the therapeutic efficacy. Therefore, polymer nanomedicines have great application prospects in the treatment of osteosarcoma because of their unique advantages.

Key words: osteosarcoma, polymer, nanoparticle, controlled drug delivery, tumor therapy, polymer nanomedicine, bone tumor, tissue engineering
