概括
皮肤状细胞癌 (CSCC) 风险因素 (RF) 的数量与复发,转移和死亡风险的增加直接相关. 具体来说,具有3个RF的CSCC表明BWH T2b阶段内的风险较高的子集.
科学领域:

- 皮肤病学 皮肤病学
- 癌症风险分层化 癌症风险分层
背景情况:
- 皮肤状细胞癌 (CSCC) 的管理依赖于使用瘤分期系统的风险分层.
- 布里格姆和妇女医院 (BWH) 的T分期系统使用四个风险因素 (RF),但缺乏阶段和RF数之间的精确关联.
- BWH阶段T2b包括两个和三个RF的CSCC,需要更清晰的风险差异化.
研究的目的:
- 调查风险因素数量 (RF) 与CSCC复发,转移和与疾病相关的死亡风险之间的关联.
- 为了确定有三个RF的CSCC是否代表BWHT2b阶段内独特的高风险子集.
主要方法:
- 追溯性,跨国队列研究,包括1991年至2023年间诊断的16844种侵入性CSCC.
- CSCCs根据四个特定的RF数量进行了分层:瘤直径 (≥2厘米),组织学 (差差分化),局部延伸 (超越皮下脂肪) 和神经入侵 (大口径).
- 分析的重点是局部复发,结节转移,远程转移和疾病特定死亡的五年累积发病率.
主要成果:
- 观察到局部复发,结节转移,远程转移和疾病特异性死亡风险显著增加,随着RF数量的增加 (0至4).

Skin Cancer
3.0K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Metastasis
5.5K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Cancer Stem Cells and Tumor Maintenance
4.7K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Mitogens and the Cell Cycle
6.4K
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...

Cancer Survival Analysis
315
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Adaptive Mechanisms in Cancer Cells
5.7K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
