概括
质子束疗法 (PBT) 比传统的X射线疗法 (XRT) 更具成本效益,用于中等收入国家的儿科脑髓母细胞瘤. 这项分析强调了PBT的长期益处,特别是考虑到认知功能,尽管最初的成本更高.
科学领域:
- 在瘤学瘤学.
- 辐射疗法 辐射疗法
- 卫生经济学 卫生经济学
背景情况:
- 儿童癌症幸存者面临着显著的长期成本和放射治疗的副作用.
- 质子束疗法 (PBT) 在减少这些长期问题方面提供了潜在的好处,但会带来更高的前期成本.
- 在中等收入国家实施像PBT这样的先进治疗方法需要进行彻底的成本效益分析.
研究的目的:
- 为了评估PBT的成本效益与传统光子束疗法 (XRT) 相比,用于儿科脑髓母细胞瘤.
- 将最新的临床结果和长期副作用数据纳入经济模型.
- 在中等收入国家的经济背景下评估PBT的可行性.
主要方法:
- 马尔科夫和蒙特卡洛模拟模型被用于分析.
- 关于死亡率,治疗副作用 (激素缺乏,听力损失,二次脑瘤,甲状腺癌,智商下降) 和相关公用事业的数据是从文献中编制的,并根据中等收入国家 (泰国) 的情况进行调整.
- 经济参数,包括医疗和非医疗成本,在患者一生中被分析.
主要成果:
- 基准案例分析表明,与XRT (80,217美元,35.23公用事业) 相比,PBT的总成本较低 (69,349美元) 和更高的公用事业 (36.12美元).
- 增量成本效益比率 (ICER) 有利于PBT,负值 (-12,211美元/QALY).
- 敏感性分析证实了PBT的成本效益,尽管如果排除智商下降的机会成本,XRT似乎更具成本效益.
结论:
- 考虑到最新的临床数据,质子束疗法是中等收入国家的儿科脑髓母细胞瘤的更具成本效益的治疗选择,而不是XRT.
- PBT的长期好处,特别是减轻认知能力下降 (智商下降) 的好处,大大促进了其有利的经济形象.
- 这些发现支持在资源有限的环境中采用PBT,当长期患者结果优先考虑时.

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...

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.
