- ALアミロイドーシスにおけるB細胞成熟抗原 (BCMA) 標的治療の有効性と耐容性を検討する.
- CAR-T細胞治療をBCMA指向の治療の中で強調する.
- ALアミロイドーシスのアウトカムと再発性/耐性多発性骨髄腫 (RRMM) のアウトカムを比較する.
主な方法:
- ALアミロイドーシスにおけるBCMA誘導療法に関する文献レビュー
- CAR-T細胞療法,抗体-薬剤結合体,および双種の抗体に焦点を当てた.
- 既存のRRMM治療データとの比較分析
主要な成果:
- RR ALアミロイドーシスの潜在的な治療法として,BCMAを標的とする治療法が登場しています.

01:27Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
