まとめ
癌の家族歴は30歳から50歳の間で大きく変化し,スクリーニングの推薦に影響を与えます. これらのシフトは,パーソナライズされたがんリスク評価と早期発見戦略にとって極めて重要です.
科学分野:
- 遺伝学と流行病学について
- 癌の予防とスクリーニング
- 公衆衛生研究 公共衛生研究
背景:
- 家族のがん歴は,個々のがんリスクの評価に不可欠です.
- 早期発見のための個別化されたスクリーニングの推奨事項をガイドしています.
研究 の 目的:
- 成人期における癌の家族歴における臨床的に有意な変化の頻度を決定する.
- これらの変化が,早期またはより集中的ながんスクリーニングの勧告にどのように影響するか評価する.
主な方法:
- 記述的研究では,がん遺伝学ネットワーク (CGN) のレジストリ (1999-2009) の家族歴データを分析した.
- 遡及的および展望的分析では,出生から入学まで,入学からフォローアップまで,家族歴の変化を調査した.
- 具体的な分析は,大腸,乳がん,前立腺がんのスクリーニング基準に焦点を当てた.
主要な成果:
- 遡及的分析では,30歳と比較して50歳の高リスクスクリーニング基準が,大腸がんと乳がんの診断において増加したことが示された.
- 展望的分析によると,20年以上にわたり,100人当たり2~8人が,大腸,乳がん,前立腺がんの高リスクスクリーニング基準を満たしていた.
- 結腸直腸癌および乳がんの家族歴の変化率は,遡及分析と前向き分析の間で一貫していました.
結論:
- 臨床的に重要な癌の家族歴は,早期または激しいスクリーニングを促し,大腸,乳がん,前立腺がんの30歳から50歳の間で増加します.
- 増加は顕著ですが,前立腺がんの絶対率は低いままです.
- 家族がん歴の定期的な再評価は,成人期を通じてスクリーニングガイドラインを更新するために不可欠です.

Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Longitudinal Research
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Cancers Originate from Somatic Mutations in a Single Cell
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...
