概括
前列腺癌 (PCa) 的新辅助内分泌疗法 (NET) 显著降低前列腺特异抗原 (PSA) 和Ki-67表达,表明其作为预后生物标志物的潜力. NET也可能诱导PCa.中的神经内分泌表型.
科学领域:
- 在瘤学瘤学.
- 病理学 病理学 病理学
- 内分泌学 在内分泌学.
背景情况:
- 前列腺癌 (PCa) 管理通常涉及新辅助内分泌疗法 (NET).
- 了解后NET免疫表型变化对于治疗评估至关重要.
- 关键标记物包括雄激素受体 (AR),前列腺特异性抗原 (PSA),synaptophysin (Syn),染色素A (CgA),p53,和Ki-67.
研究的目的:
- 在PCa.NET之后调查AR,PSA,Syn,CgA,p53和Ki-67的免疫类型变化.
- 分析这些标记物变化的临床意义和预后价值.
- 探索PCa.中潜在的NET诱导的神经内分泌 (NE) 差异化.
主要方法:
- 分析了40名PCa患者在NET之前和之后的结对瘤样本.
- 免疫组织化学被用来量化AR,PSA,Syn,CgA,p53和Ki-67的表达.
- 癌症基因组图谱 (TCGA) 数据库被用于与PSA和Ki-67相关的生存分析 (无进展生存 - PFS).
主要成果:
- 在Post-NET后,平均PSA和Ki-67表达显著下降 (P<0.05).
- 相反,Syn和CgA表达水平在NET后增加 (P<0.05),这表明NE类型的表型诱导.
- 在NET (P<0.05) 后观察到较低的格里森和WHO/ISUP等级.
- 在TCGA数据中,高PSA和Ki-67表达与较短的PFS相关 (P <0.05).
结论:
- 在NET后降低PSA和Ki-67表达是PCa的有价值的预后生物标志物.
- 在前列腺癌中,NET可能会诱导神经内分泌表型.
- 监测这些免疫类型有助于评估NET的疗效和患者的预后.

Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
Cancer Vaccines
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
