まとめ
肝芽細胞腫 (HB) の小児における手術中の輸血 (IBT) は死亡リスクの増加と関連しています. この研究は,IBTが凝固病を引き起こす可能性を示唆し,小児HB患者における最適化された輸血戦略の必要性を強調しています.
科学分野:
- 小児腫瘍学
- 輸血 医学
- 手術 の 結果
背景:
- 肝臓芽細胞腫 (HB) の子供はしばしば手術中の輸血 (IBT) を受けますが,生存への影響は不明です.
- この脆弱な小児集団における輸血慣行を導くためのデータは限られている.
研究 の 目的:
- 肝臓芽細胞腫 (HB) の小児患者の手術中の輸血 (IBT) と生存結果との関連を調査する.
主な方法:
- 多中心の遡及的観察研究では,原発腫瘍切除または肝臓移植を受けた338人の小児患者 (< 18歳) が参加した (2010年 - 2019年).
- IBTと再発および死亡の関連性を評価するために,プロペンス・スコア・リウェイト (PSR) コックス比例リスクの回帰分析を使用した.
主要な成果:
- 338人の患者のうち76%がIBTを受け,主に赤血球 (pRBC) を受けた.
- IBTは治療前の疾患の拡大と複雑な切除と関連していたが,これらの差異は傾向スコアの加減によって軽減された.
- IBTを受けた患者は,手術後のヘモグロビンが高く,より多くの血/血小板輸血が必要でした. IBTは死亡リスクの2. 35倍 (PSR HR2. 35,95%CI 1. 10~5. 02) と関連しており,再発率は有意に異なっていない.
結論:
- 小児肝芽細胞腫 (HB) 患者における手術中の輸血 (IBT) は死亡リスクの増加と関連しています.
- pRBCに焦点を当てたアプローチによる不必要な輸血と凝固不全の可能性を示唆しています.
- 輸血を最小限に抑え,小児 HB 患者の治療結果を改善するために,最適な輸血戦略が必要である.

Kidney Transplant I: Introduction
60
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...
