概括
用gemcitabine/docetaxel/melphalan/carboplatin (GemDMC) 进行的连续高剂量化疗 (HDC) 在复发性生殖细胞瘤 (GCT) 中显示出有希望的存活率. 在这项研究中,贝瓦西祖马布没有改善结果.
科学领域:
- 癌症学
- 癌症研究
- 药理学
背景情况:
- 复发性生殖细胞瘤 (GCT) 在标准治疗中表现不佳.
- 高剂量化疗 (HDC) 与自身干细胞移植为一些GCT患者提供治疗选择.
- 对多次复发或耐火性GCT需要新的治疗策略.
研究的目的:
- 在复发性或耐火性GCT患者中评估配合贝瓦齐祖马布或不配合贝瓦齐祖马布的顺序性格姆西塔宾/ 德克塔塞尔/ 梅尔法兰/ 卡博普拉丁 (GemDMC) 的疗效.
- 评估贝瓦西祖马布是否与HDC有协同作用,针对GCT血管性.
- 确定这种疗法是否可以改善预期的结果.
主要方法:
- 在三个队列中进行了一项涉及序列性贝瓦齐祖马布-GemDMC,其次是贝瓦齐祖马布-ifosfamide/carboplatin/etoposide (ICE) 的试验.
- 资格标准包括第二次或后来的复发或低风险的第一次复发.
- 结果在额外的试验之外的队列中得到验证.
主要成果:
- 治疗了165名多次复发/ 耐药性GCT的男性患者.
- 总体应答率为84. 5%,其中77%的患者获得完全或部分缓解.
- 五年无复发存活率 (RFS) 和整体存活率 (OS) 分别为57. 1%和58. 3%.
- 在接受贝瓦齐祖马布和不接受贝瓦齐祖马布的患者之间没有显著的结果差异.
结论:
- 顺序的GemDMC- I) CE化疗有效地增加了低风险的复发性GCT,超过了预期的结果.
- 在该患者群体中,贝瓦齐祖马布没有显著改善RFS或OS.
- 已确定的治疗方案为晚期GCT患者提供了可行的治疗选择.

Treatment Resistant Cancers
3.4K
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...

Combination Therapies and Personalized Medicine
5.1K
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.

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
