概括
胰腺癌的分子检测在边界切除和局部晚期病例中未得到充分利用. 常规分子检测可以识别更多可向突变,改善患者的治疗结果.
科学领域:
- 在瘤学瘤学.
- 分子诊断学 分子诊断
- 胃肠病学 胃肠病学
背景情况:
- 国际指南建议对晚期胰腺癌进行分子检测.
- 在晚期胰腺癌中,可操作的分子变化很少发生.
- 在边界切除 (BRPC) 和局部晚期胰腺癌 (LAPC) 中分子测试的临床实用性尚未得到充分证实.
研究的目的:
- 在现实环境中评估BRPC和LAPC患者分子测试的利用和结果.
- 评估这个患者队列中分子测试 (微卫星不稳定性和KRAS状态) 的频率和结果.
主要方法:
- 一项基于人口的前性研究 (NORPACT-2) 在2018-2020年期间包括188名BRPC和LAPC患者.
- 分子测试是根据治疗瘤学家的裁量进行的,而不是作为例行调查.
- 分析了MSI和KRAS测试的频率和结果.
主要成果:
- 只有30名患者 (16%) 接受了分子检测.
- 一名患者 (3.6%) 检测到微卫星不稳定性 (MSI),并在免疫疗法和手术后实现完全反应.
- 一名患者 (14.3%) 进行KRAS野生型测试.
- 在特定的医院信托基金中接受FOLFIRINOX化疗或治疗与更高的分子测试率相关.
结论:
- 分子检测很少在BRPC或LAPC患者中进行.
- 对所有BRPC和LAPC患者实施常规分子检测可能会加强对可向突变的鉴定.
- 更多地识别可向突变可能会导致改善患者的治疗结果.

Combination Therapies and Personalized Medicine
4.9K
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...

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.
