まとめ
malignant perivascular epithelioid cell tumors (PEComas) は,まれで攻撃的である. この疾患は,乳房内皮質細胞腫瘍 (PEComas) と呼ばれる. この症例は 標準的な治療に耐性のある中枢性PEComaを強調し 新しい治療戦略の必要性を強調しています
科学分野:
- 腫瘍学
- 病理学について
- 軟組織腫瘍
背景:
- 周血管性上皮細胞腫瘍 (PEComa) は稀な軟組織腫瘍である.
- 悪性PEComaは極めてまれで,転移や局所的な再発を含む攻撃的行動を示す可能性があります.
- 非切除性または転移性PEComaの治療法は,従来の化学療法および放射線治療に対する耐性のために制限されています.
研究 の 目的:
- 肺の置換を伴う非常に攻撃的なPEComaの症例を示します.
- このような希少で攻撃的なPEComaの管理における臨床的経過と課題を強調する.
- 非切除性または転移性PEComaの現在の治療戦略をレビューする.
主な方法:
- 59歳の男性患者の詳細な臨床報告
- シロリムスと放射線療法による全身療法にもかかわらず,疾患の進行を記録する.
- メディアスティナルPEComaと治療パラダイムに関する既存の文献のレビュー.
主要な成果:
- 患者さんは非常に攻撃的な悪性ペコマを発症し,中腹部に侵入し,右側の中腹部と下方の肺の葉を置き換えました.
- 腫瘍は全身シロリムスと放射線治療に耐性を示した.
- これは,中枢骨に侵入した悪性PEComaの報告された数少ないケースの1つを表しています.
結論:
- 悪性PEComaは,攻撃的な局所的侵入と標準治療に対する耐性を表す可能性があります.
- PEComaによる中腸内侵入は 非常にまれですが 壊滅的な表現です
- 侵襲的で切除不能なPEComaに対する新たな治療戦略に関するさらなる研究が必要である.

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Cancer Cell Migration through Invadopodia
2.4K
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

The Tumor Microenvironment
6.8K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Tumor Progression
6.5K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
