まとめ
フルクインチニブは,若年および高齢の結腸直腸がん患者において,比較可能な安全性プロファイルを示しています. この研究は,フルクインチニブが異なる年齢層における安全な治療法であり,併用療法が有望であることを示唆しています.
科学分野:
- 腫瘍学
- 臨床薬理学
- 現実 の 世界 の 証拠
背景:
- 結腸直腸がん (CRC) の発生率は,中国では若年成人 (< 50歳) で増加しており,臨床試験ではしばしば不足している.
- CRCの高齢者集団 (≥65歳) も過小評価されており,年齢スペクトルにおける治療結果のより深い理解が必要である.
- 前回の第4相試験では,中国人の転移性CRC (mCRC) の患者でフルクインチニブの管理可能な安全性プロファイルが示されました.
研究 の 目的:
- 結腸直腸がん患者の特定の年齢サブグループにおけるフルクインチニブの安全性と耐容性を評価する.
- 若年 (< 50歳) と高齢者 (≥75歳) のCRC患者の治療の強度と有害事象のプロフィールを比較する.
- これらの年齢層における併用療法と単独治療の有効性を評価する.
主な方法:
- 中国人の大腸がん患者におけるフルクインチニブ第4相試験 (NCT04005066) の実態分析.
- 患者は2019年4月から2022年9月までのデータで,若者 (<50歳) と高齢者 (≥75歳) のサブグループに分類されました.
- 治療による有害事象 (TEAE) や治療に関連する有害事象 (TRAE) を含めた安全性に関する結果が細かく記録され,分析されました.
主要な成果:
- この研究には512人の若者と239人の高齢のCRC患者が参加した. 若い患者はより集中的な治療を受けた (中位は2. 75ヶ月対2. 40ヶ月).
- TEAEの発生率は,若年 (78. 71%) と高齢者 (77. 41%) のグループでは同様でした. 両グループで発生したTRAEには,手足・足の赤血症 (PPES) と高血圧が含まれていた.
- 若い患者 (4. 10 vs 2. 40ヶ月) と高齢患者 (3. 90 vs 2. 10ヶ月) の両方で,併用治療は単体治療よりも長い期間を示した.
結論:
- フルクインチニブは,大腸がんを患った若年成人および高齢者を含め,異なる年齢層で比較可能な安全性プロファイルを示しています.
- 若いCRC患者はより集中的なフルクインチニブ治療を受ける傾向があり,この薬は高齢者にとっても安全な選択肢です.
- 治療期間を長引けた組み合わせは,若年および高齢のCRC患者で治療結果を最適化するための有望な戦略を示唆しています.

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
95
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
86
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...

Cancer Prevention
7.2K
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.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
