まとめ

画像による適応型冷凍療法 (ImAC) は,針の位置精度を向上させることで,前立腺がんの治療を最適化します. この新しいアプローチは,効果的な焦点冷凍処理に必要な経験を減らす可能性があります.

科学分野:

泌尿器科
医療用イメージング
腫瘍学

背景:

焦点冷凍治療は前立腺がんの治療法で副作用が少なくなります
医者の経験は,冷凍処理中の針の傾斜の管理に不可欠です.

研究の目的:

MRIによる前立腺冷凍治療のための画像誘導適応冷凍療法 (ImAC) の開発と評価.
ImACが注射針の位置を最適化し,医師の経験要求を減らすことができるかどうかを判断する.

主な方法:

ImACは,針の傾きと氷球の形成を考慮して最適な針の位置を計算するために設計されました.
システムの性能は21の針挿入のシミュレーションによって評価されました.

主要な成果:

ImACは,経験豊富な医師 (3. 4 mm) と比較して,より高い中間最小アブレーションマージン (5. 0 mm) を達成しました.
針の位置調整は,ImACと医師の間で似ていた (± 7. 5 mm).

結論:

ImACは,前立腺冷凍手術における針の位置を最適化する可能性を示しています.
この適応的戦略は効果的な冷凍処理の手順の学習曲線を短縮するかもしれません

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Targeted Cancer Therapies

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.
There are several types of targeted therapies against specific...

Treatment 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...

Tumor 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.
