- 乳腺癌研究研究 乳腺癌研究
- 手术病理学手术病理学
背景情况:
- 淋巴结转移是乳腺癌的一个关键预后因素.
- 虽然瘤的大小和位置是已知的风险因素,但它们与特定受体亚型和节点参与的相互作用需要进一步澄清.
研究的目的:
- 为了研究原发性瘤特征 (大小,位置) 和淋巴结转移在不同雌激素受体 (ER) 阳性乳腺癌亚型之间的关联.
- 阐明孕激素受体 (PR) 和人体表皮生长因子受体2 (HER2) 状态如何改变这些关联.
主要方法:
- 在1998-2019年间诊断的618名ER阳性乳腺癌患者的回顾性图表审查.
- 排除特定疾病类型 (如炎症性,转移性) 和治疗方法 (新辅助化疗).
- 使用描述性统计,克鲁斯卡尔-瓦利斯和奇方/费舍尔精确测试进行统计分析,以评估瘤特征和结节状况之间的关系.
主要成果:
- 在ER+/PR+/HER2+,ER+/PR+/HER2+和ER+/PR-/HER2-亚型中发现了较大的中位瘤大小和节点阳性之间的显著关联.
- 患有ER+/PR+/HER2瘤的节点阳性患者的瘤到乳头的距离显著缩短.

Mitogens and the Cell Cycle
6.5K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

The Tumor Microenvironment
6.6K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Disorders of the Female Reproductive System
366
The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...
