- 病理学 病理学 病理学
背景情况:
- 胰腺酸性细胞癌 (PACC) 是胰腺腺癌的罕见亚型,占病例的1-2%.
- PACC源于细胞,可以呈现混合组织学.
- 诊断依赖于形态学和BCL10免疫组织化学.
研究的目的:
- 总结PACC的关键特征,包括它的流行病学,诊断和分子景观.
- 突出PACC和胰腺管道腺癌 (PDAC) 之间致癌的差异.
- 强调分子分析对PACC治疗个性化的重要性.
主要方法:
- 审查现有的文献和关于PACC的回顾性研究.
- 对组织学和免疫组织化学诊断标准的分析.
- 检查分子变化,包括突变和缺陷.
主要成果:
- PACC瘤通常较大,不那么具有攻击性,淋巴结参与度较小,预后比PDAC更为有利.
- 与PDAC不同,KRAS突变在PACC中并不常见.
- 同源重组缺陷 (HRD),通常与生殖线BRCA2突变相关,是常见的 (30%),与较罕见的BRAF突变和MMR缺陷一起.

01:30Acute Pancreatitis II: Clinical Manifestations and Management
1.0K
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

01:24Chronic Pancreatitis I: Introduction
832
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
