概括
前列腺放射治疗 (PRT),骨盆节点放射治疗 (PNRT) 和雄激素剥夺疗法 (ADT) 可以导致前列腺癌患者的骨髓抑制. 虽然显著,但在本研究中临床影响是有限的,尽管建议谨慎使用组合疗法.
科学领域:
- 在瘤学瘤学.
- 辐射瘤学 辐射瘤学
- 血液学 血液学 血液学
背景情况:
- 前列腺癌 (PCa) 管理通常涉及前列腺放射治疗 (PRT),盆腔节点放射治疗 (PNRT) 和雄激素剥夺疗法 (ADT).
- 这些治疗方法导致骨髓抑制的风险尚未得到充分证实.
- 本研究旨在评估与PRT相关的骨髓抑制风险.
研究的目的:
- 在前列腺癌患者中全面评估与PRT,PNRT和ADT相关的骨髓抑制风险.
- 分析不同治疗组合和放射治疗技术对血液参数的影响.
主要方法:
- 在2007年至2017年期间治疗的600名前列腺癌患者的回顾性分析.
- 根据治疗方法分为四个队列:单独使用PRT,使用PRT+ADT,使用PRT+PNRT和使用PRT+PNRT+ADT.
- 在多个时间点评估血红蛋白,白血球,中性粒细胞,淋巴细胞和血小板,用放射治疗技术 (3D-CRT,IMRT) 进行分层.
主要成果:
- 在HGB和LYM值中观察到显著的基线差异.
- PRT + PNRT + ADT队列在基线和RT后1个月显示出显著较低的HGB.
- 在RT后1个月和1年,ADT显著影响了BM抑制. 此外,PNRT也显著影响了BM抑制,并增加了减少白细胞计数的几率.
- RT技术,特别是与PNRT和ADT相结合,增加了LYM数量较低的几率. PRT + PNRT + ADT 减少了 NEUT 和 PLT 的数量.
结论:
- PRT,ADT,PNRT和3D-CRT与骨髓抑制 (BMS) 有关.
- 尽管存在统计学上显著的风险,但没有患者需要为BMS管理进行额外的干预.
- BMS的临床影响似乎有限,但它的重要性值得与新型全身性药物一起考虑.

Cancer Therapies
7.6K
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...

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.
