概括
儿科MATCH试验表明返回生殖线结果是可行的. 这种方法在6.3%患有耐火性癌症的儿科患者中确定了致病性/可能致病性癌症倾向基因变异,突出了系统的生殖线随访的必要性.
科学领域:
- 在瘤学瘤学.
- 遗传学 是一个遗传学.
- 临床试验 临床试验
背景情况:
- 精确瘤学通常依赖于瘤检测可采取行动的变化.
- 儿科MATCH试验的目的是评估在合作小组环境中返回生殖线结果的可行性.
- 它还试图在患有耐火性癌症的儿科患者中表征生殖癌症倾向.
研究的目的:
- 评估在国家癌症研究所-儿童瘤组儿科MATCH试验中返回生殖结果的可行性.
- 在患有耐火性癌症的儿科患者中表征生殖癌症倾向.
- 评估欧洲医学瘤学会 (ESMO) 关于生殖线随访的指南的有用性.
主要方法:
- 来自1,167名患有耐火性癌症的儿科患者 (年龄为1-21岁) 的瘤和血液DNA接受了基因面板测序.
- 在38个癌症倾向基因 (CPG) 中识别致病/可能致病 (P/LP) 变异的临床生殖系报告被返回研究地点.
- 评估了ESMO对CPGs瘤变异的生殖线随访的建议.
主要成果:
- 在21个CPG中,含有P/LP变体的生殖系报告产生了6.3%的患者.
- 同时的生殖系发现在经常突变的CPG中有所不同,NF1为25.0%和TP53为15.3%.
- 根据ESMO的指导方针,推对30.5%的瘤CPG变体进行临床随访,包括57.1%的确定的生殖系变体.
结论:

Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Combination 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...

Cancer-Critical Genes II: Tumor Suppressor Genes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Mismatch Repair
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...
