概括

与新发黑色素瘤相比,遗传倾向和高瘤密度显著增加了瘤相关黑色素瘤 (NAM) 的风险. 这些因素,以及特定性别的身体部位分布,对于理解黑色素瘤的发展至关重要.

科学领域:

皮肤病学皮肤病学
流行病学流行病学
遗传学遗传学是一个

背景情况:

缺少前性流行病学研究,调查关黑色素瘤 (NAM) 和新发黑色素瘤的遗传与环境因素.
了解不同的风险因素概况对于有针对性的预防和早期检测策略至关重要.

研究的目的:

为了确定风险因子概况是否在神经瘤相关黑色素瘤 (NAM) 和新型黑色素瘤之间有所不同.
调查这些风险关联中的潜在基于性别的差异.

主要方法:

澳大利亚昆士兰州的一项基于人口的前性队列研究 (QSkin Study),涉及38701名年龄在40-69岁之间的参与者.
收集的数据包括表型因素,阳光照射史和黑色素瘤和神经瘤发展的多基因风险评分.
突发性侵袭性黑色素瘤 (与神经瘤相关的和新的) 是主要结局,随访时间为2022年12月.

主要成果:

高瘤密度和对黑色素瘤发展的高遗传倾向显示,NAM的危险比率明显高于de novo黑色素瘤.
表型和阳光暴露因素与这两种黑色素瘤类型有着相似的关联.
虽然在NAM风险因素方面没有发现显著的性别差异,但年龄较大是男性新发黑色素瘤的较强风险因素. 根据性别,NAM的分布有所不同,男性更常见地在干部受影响,女性在四肢受影响.

结论:

对于神经瘤相关的黑色素瘤 (NAM) 和新发性黑色素瘤,存在不同的风险因素概况,多基因风险和神经瘤倾向是关键的差异化因素.
针对NAM的性别特定的身体部位分布可能会为定制的早期检测方法提供信息.

Skin Cancer

Skin Cancer

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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Pigmentation

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Induced Pluripotent Stem Cells

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
Somatic...
