Research square
|September 2, 2025
概括
癌症控制需要确定高风险人群 (热点). 这项研究发现乳腺癌,结肠直肠癌和肺癌热点的空间差异显著,乳腺癌和肺癌的晚期诊断重叠更大.
科学领域:
- 流行病学
- 地理空间分析
- 公共卫生
背景情况:
- 癌症控制策略取决于识别高风险人群,称为热点,用于新的或晚期诊断.
- 了解癌症热点的空间分布对于有针对性的干预至关重要.
- 之前的研究还没有完全描述癌症热点是如何因癌症类型或诊断结果而异的.
研究的目的:
- 研究乳腺癌,结直肠癌和肺癌发病率和晚期诊断的热点的地理空间异质性.
- 将不同癌症部位的发病率和晚期癌症热点之间的空间重叠进行比较.
- 确定协调癌症控制工作的潜在领域.
主要方法:
- 在印第安纳州诊断出女性乳腺,结直肠和肺癌的成年患者的分析 (2010-2019).
- 用于准确识别热点,将病人的住所位置数据分解到近似的个别点级别.
- 应用核心比率估计以确定具有统计意义的癌症热点,并比较热点区域和重叠.
主要成果:
- 这项研究包括117,305名乳腺癌 (51,623名),结肠直肠癌 (25,160名) 和肺癌 (37,522名) 患者.
- 对所有三种癌症类型 (32km2 - 165km2) 的发病率和晚期热点之间存在很小的空间差异.
- 在不同癌症部位 (408平方公里-1046平方公里) 的晚期热点中发现了更大的重叠,特别是在乳腺癌和肺癌之间.
结论:
- 癌症热点存在相当大的地理空间异质性,因结果和癌症部位而异.
- 尤其是乳腺癌和肺癌的晚期热点重叠,
- 使用分类空间数据可以提高癌症热点比较的精度,并为协调的公共卫生干预提供信息.

lncRNA - Long Non-coding RNAs
8.9K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Mouse Models of Cancer Study
5.7K
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Cancers Originate from Somatic Mutations in a Single Cell
12.7K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
