まとめ
肺のノードルを持つ乳がん患者にとって,マイクロ波アブレーション (MWA) によるCT誘導肺生検は安全で有効です. このアプローチは,悪性腫瘍の疑いを管理し,生存率を向上させ,進行しない生存を可能にします.
科学分野:
- 腫瘍学
- 介入放射線学
- 肺科
背景:
- 乳がん患者は手術後に 単独の肺結節を発症することが多い.
- 正確な診断とこれらの結節の効果的な管理は,患者のアウトカムにとって極めて重要です.
- CTによる肺バイオプシーとマイクロ波アブレーション (MWA) は,侵襲性の少ない治療法です.
研究 の 目的:
- MWAと組み合わせたCT誘導肺生検の安全性と有効性を評価する.
- 徹底的な手術後の乳がん患者の単独の悪性肺結節の管理を評価する.
主な方法:
- 乳がん患者37人を対象に遡及研究を行いました.
- 患者は2014年1月から2018年12月の間にCT誘導肺生検とMWAを受けた.
- 臨床的結果と合併症を分析した.
主要な成果:
- 転移性侵襲性管がん (乳腺発症) は,患者の81. 1%で確認されました.
- 13. 5% の患者で診断された原発性肺がん
- 主要な合併症は肺胸 (21. 6%),胸痛 (16. 2%) および血栓症 (10. 8%) であった.
- 転移した症例の2年,3年,5年生存率はそれぞれ86. 2%,58. 3%と35. 3%であった.
- 病変の進行のない生存期間の中央値は35ヶ月,全生存期間の中央値は44ヶ月でした.
結論:
- MWAによるCT誘導肺生検は安全で効果的な治療法です.
- この組み合わせのアプローチは,乳がんの生存者における,単独の悪性肺結節の疑いを管理するのに役立ちます.
- この手法は転移性疾患の生存に有望な結果を示しています.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
1.0K
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
732
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
1.1K
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
