概括
HER2-低和HER2-超低的表达在唾液腺癌中很常见,包括唾液管癌和其他类型. 这些发现表明,在治疗这些罕见癌症时,HER2向治疗的潜力很大.
科学领域:
- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 新型抗HER2抗体-药物联合体在乳腺癌治疗中显示出前途.
- 在先进的固体瘤中,越来越多地识别了HER2-low和HER2-ultra-low的表达.
- 唾液腺癌代表了一组多样化的罕见癌症.
研究的目的:
- 研究唾液腺癌中HER2-低和HER2-超低免疫表达的频率.
- 为了确定HER2表达模式是否在唾液管癌 (SDC) 和非SDC之间有所不同.
- 评估 HER2 向疗法在唾液腺癌中的潜在适用性.
主要方法:
- 对81例唾液腺癌病例的回顾性分析.

- 瘤的分类为HER2-阳性 (3+),HER2-低 (1+和2+) 和HER2-超低 (0+).
主要成果:
- 在34%的SDC中发现了HER2-阳性 (3+) 瘤,但在非SDC中没有发现.
- 在63%的SDC中观察到HER2的低表达 (1+或2+),并且在非SDC亚型中存在差异 (例如,在肌上皮癌中62%,在细胞癌中56%).
- 在0%的SDC中发现HER2-超低表达 (0+),在非SDC亚型中范围为11%至33%.
结论:
- 在各种唾液腺癌中,HER2-低和HER2-超低的免疫表达很普遍,而不仅仅是SDC.
- 存在HER2-低和HER2-超低的表达表明,HER2-向治疗可能是一个可行的治疗选择,具有唾液腺癌的大量患者.

Salivary Glands and Saliva
2.5K
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...

Exocrine Glands: Unicellular and Multicellular Glands
32.5K
Exocrine glands are classified as unicellular and multicellular. The unicellular glands are scattered single cells, such as goblet cells, found in the mucous membranes of the small and large intestines. On the other hand, multicellular exocrine glands develop as secretory sheets, like the internal lining of the abdomen or chest. Such secretory sheets release their secretions directly into the lumen of these organs. In addition, some multicellular glands have deep-seated secretory units to...

The Pituitary Gland
10.8K
The pituitary is a small endocrine organ in the sphenoid bone under the hypothalamus. Primarily, the pituitary in adults has two distinct anatomical and functional regions— the anterior and posterior lobes. During human fetal development, a third pituitary gland region called the pars intermedia atrophies and disappears. However, some of its cells migrate and exist adjacent to the anterior pituitary in adults.

The Parathyroid Glands
5.3K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

The Pineal Gland
5.2K
The pineal gland, a diminutive endocrine structure named for its pinecone-shaped appearance, is situated atop the third ventricle within the diencephalon region of the forebrain. This gland, composed of secretory cells known as pinealocytes arranged in compact cords and clusters around dense particles of calcium salts, plays a pivotal role in hormonal regulation.
The primary secretion of the pineal gland is the hormone melatonin, derived from serotonin. The concentration of melatonin in the...

The Mammary Glands

The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...
