胰腺癌每年在全球导致数百万人死亡,是最常见的死亡原因之一,需要及时治疗。
胰腺癌每年在全球范围内导致数百万人死亡,是最常见的死亡原因之一,需要及时治疗。大量胰腺癌患者在晚期才被检出,肿瘤无法治愈且耐药,因此胰腺癌的总生存率较低。这种癌症的晚期阶段是由于致癌基因的表达、抑癌基因的失活以及不同细胞信号通路中分子的失调所导致的。通过生物标志物进行及时诊断可显著延缓进展并提高生存率。间皮素、尿激酶型纤溶酶原激活物、IGFR、表皮生长因子受体、Plectin-1、Mucin-1和锌转运蛋白4的过表达已被证实在胰腺癌诊断中具有意义。纳米技术促进了基于纳米载体的制剂(脂质、聚合物、无机、碳基及先进纳米载体)的发展,这些制剂克服了传统疗法、化疗和放疗的障碍,而这些传统疗法会对邻近健康组织造成毒性。生物相容性、毒性和大规模制造是与基于纳米载体的方法相关的障碍。目前,基于免疫治疗的技术已成为预防癌症的有效治疗替代方案。免疫检查点靶向技术在人类癌症中已显示出显著疗效。检查点抑制剂、过继性T细胞疗法和癌症疫苗的最新进展已显示出克服胰腺癌细胞免疫逃逸机制的潜力。将这些免疫治疗方法与纳米载体相结合,在增强抗肿瘤反应和改善患者生存方面具有巨大前景。
Pancreatic cancer kills millions of people worldwide each year and is one of the most prevalent causes of mortality that requires prompt therapy. A large number of people suffering from pancreatic cancer are detected at an advanced stage, with incurable and drug-resistant tumor, hence the overall survival rate of pancreatic cancer is less. The advance phase of this cancer is generated because of expression of the cancer-causing gene, inactivation of the tumorsuppressing gene, and deregulation of molecules in different cellular signalling pathways. The prompt diagnosis through the biomarkers significantly evades the progress and accelerates the survival rates. The overexpression of Mesothelin, Urokinase plasminogen activator, IGFR, Epidermal growth factor receptor, Plectin-1, Mucin-1 and Zinc transporter 4 were recognized in the diagnosis of pancreatic cancer. Nanotechnology has led to the development of nanocarriersbased formulations (lipid, polymer, inorganic, carbon based and advanced nanocarriers) which overcome the hurdles of conventional therapy, chemotherapy and radiotherapy which causes toxicity to adjacent healthy tissues. The biocompatibility, toxicity and large-scale manufacturing are the hurdles associated with the nanocarriers-based approaches. Currently, Immunotherapybased techniques emerged as an efficient therapeutic alternative for the prevention of cancer. Immunological checkpoint targeting techniques have demonstrated significant efficacy in human cancers. Recent advancements in checkpoint inhibitors, adoptive T cell therapies, and cancer vaccines have shown potential in overcoming the immune evasion mechanisms of pancreatic cancer cells. Combining these immunotherapeutic approaches with nanocarriers holds great promise in enhancing the antitumor response and improving patient survival.
