まとめ
3回のCEV化学療法 (カルボプラチン,エトポシド,ビンクリスティン) は,高リスクの網膜芽細胞腫の6回のサイクルに劣らない. この発見は,副作用とコストを減らす,より低濃度の治療法を支持しています.
科学分野:
- 小児腫瘍学
- 眼科について
- 臨床試験
背景:
- 補助化学療法は,網膜芽細胞腫の治療に不可欠です.
- 限られた対照試験では,高リスク患者の異なるCEV化学療法サイクル数を比較した.
研究 の 目的:
- CEV化学療法の3サイクルが,高リスクの病理的特徴を持つ単細胞性網膜芽細胞腫の6サイクルより劣らないかどうかを判断する.
主な方法:
- ランダム化され,オープンな非劣等性試験で,核化された片側網膜芽細胞腫の患者187人が参加した.
- 患者は3回か6回のCEV化学療法を受けた.
- 主要エンドポイントは5年生存率でした.
主要な成果:
- 3サイクルでの5年無病生存率は90. 4%, 6サイクルでの89. 2%で,不劣度基準を満たした.
- 3サイクルグループは有害事象が少なく,生活の質が向上し,コストが低下しました.
- 追跡期間の中央値は79ヶ月でした.
結論:
- 高リスクの網膜芽細胞腫では,CEV化学療法の3サイクルが,6サイクルに劣らない有効な代替薬です.
- これは低濃度化療法を支持し 患者の治療結果を改善し 医療負担を軽減します

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...
The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Clinical Trials
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

Clinical Trials: Overview
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
