类和未分类细胞癌 (RCCs) 是侵袭性癌. 分子分析和向治疗,包括免疫检查点抑制剂,为这些具有挑战性的瘤提供了新的希望.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學.
- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 类癌和未分类细胞癌 (RCCs) 由于侵略性行为和不良预后,存在诊断和临床挑战.
- 类转变涉及高度脱差与恶性状细胞,而未分类的RCC缺乏明确的分类.
- 这些侵略性瘤往往表现出诸如形,亡和高线粒细胞发生率之类的特征.
研究的目的:
- 审查萨尔科马类和未分类的RCCs的诊断,分子和临床特征.
- 突出了解这些罕见的RCC亚型的遗传基础和治疗策略的最新进展.
- 强调整合基因病理学,免疫类型和分子数据的重要性,以改善患者的治疗结果.
主要方法:
- 对组织病理学和免疫组织化学发现的审查,包括诸如细胞克拉丁,EMA,PAX8,PD-L1和p53等标志物.
- 基因组分析以识别反复发生的突变 (TP53,BAP1,CDKN2A) 和融合 (NF2,SETD2,ALK/NTRK).
- 临床相关性与瘤阶段,进展和对治疗的反应,包括VEGF抑制剂和免疫检查点抑制剂.
主要成果:
- 类RCC显示了状细胞形态和特定突变 (TP53,BAP1,CDKN2A).
- 未分类的RCC被重新定义为具有明显遗传变化的分子子组 (NF2,SETD2,ALK/NTRK融合).
- 这两种亚型都与晚期,快速进展和对VEGF向治疗的耐药性相关,但显示出免疫治疗的潜在益处,特别是PD-L1阳性肉类瘤病例.
结论:
- 整合多样化的数据 (组织病理学,免疫组织化学,基因组学) 对于准确诊断和预后的sarcomatoid和未分类的RCCs至关重要.
- 分子洞察力揭示了共享的途径,如脱差和染色质重塑.
- 新兴的免疫疗法显示出前景,特别是PD-L1阳性类RCC,指导个性化治疗策略.

External Anatomy of the Kidney
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...
Internal Anatomy of the Kidney
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
Renal Cortex
The outermost region of the kidney is the...
Blood and Nerve Supply to the Kidney
Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of each...
