概括
基因组调整的辐射剂量 (GARD) 预测HPV+口腔癌患者的生存率. GARD的表现优于临床因素,支持个性化放射治疗剂量降级以获得更好的结果.
科学领域:
- 在瘤学瘤学.
- 辐射瘤学 辐射瘤学
- 基因组学就是基因组学.
背景情况:
- 管理HPV+口腔状细胞癌 (OPSCC) 需要减少放射治疗 (RT) 剂量,而不影响治愈率.
- 仅仅临床因素不足以确保HPV+OPSCC的安全RT剂量降级.
- 基因组调整的辐射剂量 (GARD) 可以为个性化的RT剂量选择提供信息.
研究的目的:
- 假设GARD可以指导HPV+OPSCC患者个性化的RT降级.
- 评估GARD和整体存活时间 (OS) 之间的关联.
- 将GARD的预测性能与传统的临床预测器进行比较.
主要方法:
- 在191名HPV+OPSCC患者 (AJCCI-III阶段) 中分析的基因表达特征.
- 考克斯的比例危险模型评估了GARD与OS的关联.
- 时间依赖的接收器运行特征分析将GARD与临床变量进行比较.
主要成果:

Combination Therapies and Personalized Medicine
5.9K
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...

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Targeted Cancer Therapies
8.6K
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
3.7K
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...
