まとめ
米国がん統計局 (USCS) の集団に対する国立がんデータベース (NCDB) およびサーベイランス,疫学,および最終結果 (SEER) 集団の正常化により,乳がん患者の全生存率 (OS) が類似していることが示されました. これらの発見は,NCDBとSEERデータを用いた分析が一般化可能であることを示唆しています.
科学分野:
- 腫瘍学 腫瘍学
- バイオ統計学 バイオ統計学
- 公衆衛生は公衆衛生である.
背景:
- 国立がんデータベース (NCDB) と監視,疫学,および最終結果 (SEER) プログラムは,がん研究のための重要なリソースです.
- しかし,データ収集と患者の人口統計の違いは,結果の一般化に影響を与える可能性があります.
- この研究は,米国がん統計局 (USCS) の集団にNCDBとSEERのデータを標準化することによって,これらの潜在的な制限に対処することを目的とした.
研究 の 目的:
- NCDBとSEERの集団をUSCSの集団に反映するように正常化する.
- 乳がん患者における全生存期 (OS) のアウトカムを,正常化前のおよび正常化後の試験および比較を行う.
- NCDBとSEERのデータセットからの発見の汎用性を評価する.
主な方法:
- 2010年から2018年の間にステージI-IVの乳がんと診断された患者は,NCDBとSEERから選択されました.
- USCSの比率を用いて,年齢,性別,人種/民族などの変数に基づいて,NCDBとSEERコホートを正常化するために,患者重量周波数を使用しました.
- 総生存率は,カプラン・マイヤー法 (pre- and post-normalization) を用いて推定された.
主要な成果:
- USCSコホートは2,473,739人の患者,NCDB 1,441,556人,SEER 504,938.8人の患者で構成されていました.
- 年齢と性別の分布は類似していたが,人種/民族の組成と疾患の程度において,コホート間の有意な差異が観察された.
- ステージ,HRステータス,および人種/民族によって正常化した後,5年後のOSではわずかな変化が認められたが,全生存率は比較可能であり,データセットの堅実性を示した.
結論:
- NCDBやSEERのような米国の腫瘍登録は,乳がん患者の大きなサンプルに関するデータを提供しています.
- 人口統計と病気の範囲の格差にもかかわらず,全生存結果はUSCSの人口に正常化した後も同様でした.
- 標準化されたNCDBとSEERのデータを用いた分析は,米国の乳がん集団全体に一般化できる可能性が高い.

Cancer Survival Analysis
776
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...

Survival Curves
751
Survival curves are graphical representations that depict the survival experience of a population over time, offering an intuitive way to track the proportion of individuals who remain event-free at each time point. These curves are widely used in fields such as medicine, public health, and reliability engineering to visualize and compare survival probabilities across different groups or conditions.

Survival Tree
439
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Predicting Reaction Outcomes
11.0K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Cancer Stem Cells and Tumor Maintenance
6.1K
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...

Outcomes of Glycolysis
107.8K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...
