まとめ
腫瘍の分化が,早期の口腔状細胞癌 (OSCC) の選択頸部解剖 (END) 決定を導く. ENDは,中等分化および差分化腫瘍の生存率を向上させるが,分化がよくない腫瘍の生存率を向上させる.
科学分野:
- 腫瘍学 腫瘍学
- 頭と首の外科手術です.
- がん研究 がん研究
背景:
- 初期段階の口腔状細胞癌 (OSCC) は,隠されたリンパ節転移のリスクを伴う.
- 選択頸部解剖 (END) は,このリスクを管理するために使用されていますが,選択基準は議論されています.
- 初期段階のOSCCに対するENDの誘導における腫瘍の差別化の役割については,さらなる評価が必要である.
研究 の 目的:
- 腫瘍の分化が,初期段階の口腔平分細胞癌 (OSCC) の選択頸部解剖 (END) に関する意思決定を導くことができるかどうかを判断する.
主な方法:
- 監視,疫学,および最終結果 (SEER) データベースを利用して,ステージI/IIのOSCCの患者を特定しました.
- カプラン・マイヤーとコックスの回帰分析を行い,腫瘍の分化に基づいて,ENDとENDでないグループ間の生存結果 (がん特異生存率[CSS]と全生存率[OS]) を比較した.
- ENDの生存効果に対する腫瘍の部位と大きさの影響を評価するために,層別分析を行った.
主要な成果:
- 10,396人の患者の中で,ENDは,よく区別された腫瘍の生存率を向上させませんでした.
- ENDは,中等分化および差分化/無分化腫瘍におけるCSSとOSを著しく改善した.
- 腫瘍の部位と大きさは,ENDの生存効果を変化させ,微妙に微分化した小腫瘍や口腔の床にある腫瘍の生存効果は限られたものであった.
結論:
- 腫瘍の差別化は,初期OSCCにおけるENDの生存効果を決定する重要な要因である.
- ENDは,中等または差分化/無差分化腫瘍を有する患者に考慮する必要があります.
- ENDは,分化が良くなった腫瘍の患者には不要かもしれません.

Psychosexual Stages of Personality: Oral
3.2K
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

What is Population Genetics?
65.0K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Graded Potential
7.1K
Graded potentials are localized fluctuations in the cell membrane's electrical charge, commonly found in the dendrites of neurons. The magnitude of these potential changes depends on the strength of the initiating stimulus. In a membrane at its resting potential, a graded potential signifies a voltage shift either above -70 mV or below -70 mV.
Graded potentials fall into two categories: depolarizing and hyperpolarizing. Depolarizing graded potentials typically occur when sodium (Na+) or...

Conservation of Small Populations
17.4K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Population Growth
28.7K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.
