まとめ
手術後の血清CYFRA21- 1 (poCY) レベルは,急性腎臓切除術 (RNU) の後の上道尿路がん (UTUC) 患者の早期進行を予測することができます. 補助化学療法による潜在的利益を示唆する.
科学分野:
- 尿腫瘍学
- 外科腫瘍学
- バイオマーカーの研究
背景:
- 現在のガイドラインでは,急性腎臓切除術 (RNU) を受けている上管尿路癌 (UTUC) 患者に対して血清腫瘍マーカーを推奨していません.
- RNU後の早期進行に対する,手術後の血清C端値 (CYFRA21- 1, poCY) の予後値は十分に確立されていません.
研究 の 目的:
- 術後の血清CYFRA21-1 (poCY) レベルが,RNUで治療されたUTUC患者における早期疾患進行の予測因子としての有用性を評価する.
- RNU後の癌特異生存率 (CSS) と無進行生存率 (PFS) の独立した予後要因を特定する.
主な方法:
- RNUで治療された117人のUTUC患者群を分析した.
- 患者は3. 5ng/ mlのカットオフに基づいて高 (HG) と低 (LG) のpoCYグループに分類された.
- カプラン・マイヤー分析,ログランクテスト,コックス比例リスクモデルがCSSとPFSの評価に使用された.
主要な成果:
- 5年間のCSSとPFSの比率はそれぞれ79%と66%でした.
- HGのCSSと2年間のPFSは LGと比較して著しく悪かった.
- 多変量分析では,poCY,リンパ節関与 (LNI),切除限界状態 (RM) が早期進行のための独立した予後要因として特定されました.
結論:
- 術後のCYFRA21-1 (poCY),LNI,およびRMは,RNU後のUTUC患者の早期進行を予測する有意な指標である.
- 病理学的な発見に関係なく,ポCY濃度の上昇は補助化学療法を検討することを正当化します.

01:24Serum Studies: Renal Function Tests
43
Renal function tests are crucial for assessing kidney health, monitoring disease progression, and evaluating the kidneys' efficiency in waste elimination, fluid balance, and electrolyte regulation. These tests offer critical insights into kidney function, even though routine measurements may appear normal until there is a significant decline in the glomerular filtration rate or GFR. Typically, signs of kidney impairment only become evident when the GFR falls to about 50% of its normal level.

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

43
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
