Evaluating the Effectiveness of Cancer Drug Sensitization In Vitro and In Vivo
Published on: February 6, 2015
まとめ
500人のがん患者の化学療法アウトカムが評価されました. 結果は,臨床試験や専門がんセンターの外では,広範囲にわたる化学療法の使用が正当化されないことを示唆しています.
科学分野:
- 医療腫瘍学 医療腫瘍学
- クリニカル・アウトカム・リサーチ 研究結果
- 癌治療の有効性について
背景:
- 患者のアウトカム評価は,1978年に大学院の教科病院の医療腫瘍科に紹介されました.
- 最初の500人の患者の人口統計と診断データの分析.
- 癌の種類分布の比較とより広範な地域統計.
研究 の 目的:
- 患者のアウトカムを決定するために,医療腫瘍学部に紹介されます.
- 癌化学療法の効果と合併症を評価する.
- 細胞毒薬の使用の費用対効果を評価する.
主な方法:
- 1978年に連続した500人の患者を遡及的に分析した.
- 患者の人口統計,診断,受けた治療,生存率に関するデータ収集.
- 治療されたグループと未治療のグループ,および特定の化学療法レジメンを受けたグループ間の生存率の比較.
主要な成果:
- 患者の平均年齢は58歳であり,50%は診断から6週間以内に紹介されました.
- 肺がん,乳がん,頭頸がん,卵巣がん,臓がんは過剰に,胃腸がんは過小評価された.
- 患者の3分の1に治療は推奨されなかった. 治療を受けた患者のうち,247人が細胞毒薬を受けた.
- 治療を受けた患者の56%と治療を受けていない患者の52%が,1979年8月までに死亡し,生存期間の中央値は45週間 (治療を受けた) と35週間 (治療を受けていない) でした.
- 1979年8月までに"治癒的"または"補助的"化学療法を受けた50人の患者のうち17人だけが死亡しました.
- 重篤な合併症は,患者の8.8%で発生した. 細胞毒薬の費用は21万2000オーストラリアドル (薬局予算の9.3%) です.
結論:
- この研究は,厳格に設計された臨床試験または専用のがんセンターの外では,がん化学療法の広範な適用が正当化されない可能性があることを示しています.
- 研究結果は,医療腫瘍学における慎重な患者選択と治療プロトコルの評価の必要性を強調しています.
- 化学療法に関連するコストと合併症率は,がん管理における化学療法の役割を批判的に評価することを必要としています.

02:49Cancer 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...

02:57Targeted 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.

02:50Combination Therapies and Personalized Medicine
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...

02:56Treatment Resistent 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...
