概括
低骨肌量 (LSMM) 对肝细胞癌 (HCC) 患者的生存率产生负面影响,特别是在联合疗法中. 肌肉损失与更糟糕的结果和增加的副作用相关,突出其预后意义.
科学领域:
- 肝细胞癌 (HCC) 研究研究
- 癌症 尾症和身体组成分析
- 系统性治疗的有效性和预后
背景情况:
- 低骨肌量 (LSMM) 是一种已知的预测因素,预测肝细胞癌 (HCC) 患者接受全身治疗的预后不佳.
- LSMM对各种治疗方案 (包括免疫疗法和向疗法) 的结果的具体影响需要进一步阐明.
研究的目的:
- 研究接受不同全身治疗的肝细胞癌 (HCC) 患者的低骨肌量 (LSMM) 和生存结果之间的关联.
- 评估肌肉质量变化在治疗期间对预后和治疗反应的影响.
- 评估LSMM与治疗相关不良事件之间的关系.
主要方法:
- 对714名中期至高级HCC患者的回顾性分析,分为免疫疗法 (I),目标免疫疗法组合 (I+T) 和向治疗 (T) 组.
- 骨肌肉质量评估使用基于CT的第三腰椎水平骨肌肉指数 (L3-SMI) 在治疗前和3个月后.
- 使用Kaplan-Meier和Cox比例危险模型来比较整体存活率 (OS) 和无进展存活率 (PFS).
主要成果:
- 虽然LSMM患者在治疗组中的肌肉质量损失没有显著差异,但接受向治疗的非LSMM患者 (T) 与免疫疗法 (I) 相比,肌肉质量损失更大.
- 在I+T组中,客观反应与较少的肌肉质量损失有关.
- 基线,治疗后和渐进的LSMM显著与较差的中位数OS和PFS有关,特别是在I + T组. 患有LSMM的患者也表现出更高的严重不良事件 (SAE) 发病率,如风和疲劳.
结论:
- 非LSMM患者的肌肉质量变化因治疗而异,有针对性的治疗可能导致肌肉损失.
- 在HCC患者中,较大的肌肉损失与较差的治疗结果相关,包括减少存活率和增加不良事件.
- 在HCC中,LSMM是显著的预后因素,特别是在联合治疗方案下,强调身体成分监测的重要性.

Cancer Therapies
7.5K
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.
