概括
甲状腺转录因子1 (TTF-1) 是肺腺癌的敏感标记物,但缺乏特异性. 将TTF-1与Napsin-A结合起来,显著提高了肺腺癌的诊断准确度.
科学领域:
- 在瘤学瘤学.
- 病理学 病理学 病理学
- 免疫组织化学 免疫组织化学
背景情况:
- 甲状腺转录因子1 (TTF-1) 免疫组织化学 (IHC) 对于区分原发性肺腺癌至关重要.
- 然而,TTF-1表达并不仅限于肺癌,也可以在其他恶性瘤中发现,使诊断复杂化.
研究的目的:
- 评估TTF-1,Napsin-A的诊断实用性和特异性,以及各种瘤类型的大群中标记物的组合.
- 调查TTF-1在非肺腺癌,特别是胃肠道类型中被错误识别的可能性.
主要方法:
- 综合组织微阵列 (TMA) 的分析,包括152种瘤类型的17772个样本.
- 利用了纳普辛-A,CK20,SATB2,FABP1和Villin-1的现有IHC数据,以及新的TTF-1染色.
主要成果:
- 在152个瘤类别中的82个中检测到TTF-1,包括甲状腺,肺部,神经内分泌,介质瘤和胸腺瘤.
- 结合TTF-1和Napsin-A,对肺腺癌显示出高灵敏度 (85%) 和特异性 (99.1%).
- 胃肠腺癌的一个子组显示TTF-1阳性,这构成了诊断挑战.
结论:
- TTF-1是肺腺癌的高度敏感但不完全特定的标志物.

02:39lncRNA - Long Non-coding RNAs
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

01:27Tumor 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.
