まとめ
治療の便益とリスクを比較するためには、直腸がんにおける待機療法の標準化された評価項目の設定が不可欠である。臨床的完全奏効(cCR)および再発率の現在の評価方法は、患者の転帰および手術延期による真のリスクを正確に反映するために、洗練させる必要がある。
科学分野:
- 腫瘍学
- 臨床試験方法論
- 消化器外科腫瘍学
背景:
- 待機療法では、試験間での便益-リスク比の比較のために標準化された評価項目が必要である。
- 治療の便益と主要なリスク(再発)の両方を正確に評価することが不可欠である。
研究 の 目的:
- 待機療法の評価に使用される既存の評価項目を批判的に分析すること。
- 将来の研究および臨床実践のための標準化された評価項目を特定し、提案すること。
主な方法:
- 待機療法の評価で使用される評価項目を特定し、分析するために文献検索を実施した。
- 一般的に使用されている便益およびリスク評価方法の適合性を批判的に評価した。
主要な成果:
- 9つの研究で4つの便益評価項目と4つの再発率計算方法が特定され、標準化の欠如が浮き彫りになった。
- 臨床的完全奏効(cCR)率や臓器温存率といった一般的な評価項目には限界がある。
- 現在の再発率計算では、特定の患者群を除外することにより、リスクが過小評価される可能性がある。
結論:
- 標準化された評価項目を提案した:化学放射線療法後の持続的なcCR率および関連するすべての患者群を含む再発率の計算。
- 待機療法の信頼性の高い試験間比較を可能にするためには、標準化が必要である。
- 洗練された評価項目は、直腸がん管理における便益-リスクプロファイルの正確な評価を改善するだろう。

Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

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.

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...

Cancer Survival Analysis
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
