概括
在南非的一项试验中,将调制电热过热 (mEHT) 添加到化疗放射治疗中显著改善了癌症存活率. 这种可访问的治疗方法为艾滋病毒阳性和阴性患者节省了成本和带来了好处.
科学领域:
- 在瘤学瘤学.
- 医学物理 医学物理
- 公共卫生 公共卫生
背景情况:
- 低收入和中等收入国家 (LMICs) 的癌症通常在晚期出现,导致生存率差.
- 对查,诊断和治疗的获取有限,再加上高艾滋病毒患病率,加剧了LMICs,特别是撒哈拉以南非洲的癌症结果.
- 高温疗法在高收入国家已成为一种成熟的辅助癌症治疗方法,但由于可访问性问题,其在LMICs的采用受到阻碍.
研究的目的:
- 评估调制电热过热 (mEHT) 的可行性和有效性,作为南非公立医院化学放射治疗的辅助.
- 评估mEHT对包括艾滋病毒感染者在内的癌症患者无病存活率,复发率,生活质量和毒性的影响.
- 确定在资源有限的环境中将mEHT纳入癌症治疗方案的成本效益.
主要方法:
- 在南非一家公立医院进行了III期随机对照试验.
- 该试验比较了单独的化学辐射疗法与化学辐射疗法,并添加调制电热过热 (mEHT).
- 评估的结果包括5年无病生存率,复发,生活质量,毒性和成本效益,并对艾滋病毒状况进行分层.
主要成果:
- 在化学放射治疗中添加mEHT显著改善了5年无病生存率 (32%对14%;HR:0.73;p=0.049).
- mEHT减少了癌症复发,改善了患者的生活质量,而不会增加毒性.
- 在艾滋病毒阳性和艾滋病毒阴性参与者中,好处是一致的,成本效益分析表明节省成本的可能性很高.
结论:
- 调节电热高温 (mEHT) 是一种可行的,有效的化学辐射疗法LMICs的辅助,证明了显著的生存效益和成本效益.
- 在资源有限的环境中,mEHT为当地晚期癌症提供了一个有希望的,负担得起的,易于集成的治疗选择,包括HIV阳性个体.
- 需要进一步的研究来证实这些发现对撒哈拉以南非洲以外的各种医疗保健环境的概括性.

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...
