まとめ
アルベオラ軟部サーコマ (ASPS) は珍しい小児がんである. このケーススタディでは 転移性ASPS患者の詳細が示され 多科目のケアと新しい治療法の必要性を強調しています
科学分野:
- 小児腫瘍学
- 珍しい癌
- サルコマ 研究
背景:
- アルベオラ軟部肉腫 (Alveolar soft part sarcoma,ASPS) は非常に稀な軟組織肉腫であり,すべての軟組織肉腫の<1%を占める.
- ASPSは子供と青少年の5%から10%で発生します.
- 典型的な局所的な経過にもかかわらず,ASPSは高度な転移の可能性があり,包括的な管理が必要です.
研究 の 目的:
- 小児転移性ASPSの症例を提示する
- この稀な悪性腫瘍の 管理に伴う課題を説明します
- 診断の確認と新たな治療法の役割を強調する
主な方法:
- 転移したASPSの小児患者の症例報告
- 初期治療: 広い局所切除と補助放射線療法
- 診断確認:TFE3に対する免疫ヒストケミストリー
- 監視: 連続画像撮影 (F-FDG PET/CT,MRI)
- 治療:TKI,mTOR阻害剤,免疫療法 (ペムブロリズマブ),放射線療法を含む複数の全身療法.
主要な成果:
- 患者は初期局所的な制御にもかかわらず,広範囲に広がった転移 (肺,肝,脳,腹内) を発症した.
- 複数の部位で進行する疾患が観察されました.
- 患者は30ヶ月間,広範な多分野治療を受けた.
結論:
- 小児ASPSの診断には 組織病理学的および分子学的確認が不可欠です

02:56Treatment Resistant Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...
