概括
像阿特佐利祖马布加贝瓦齐祖马布 (AB) 这样的免疫疗法组合显示出肝细胞癌 (HCC) 转换的潜力,但实际的治愈转换仍然很低,这表明存在显著的转换不足问题.
科学领域:
- 肝细胞癌 (HCC) 治疗方法
- 在瘤学中免疫治疗和向治疗.
- 临床试验数据分析和流行病学.
背景情况:
- 基于免疫治疗的全身治疗疗法在非治愈性肝细胞癌 (HCC) 中实现治愈性转换的疗效正在研究中.
- 阿特佐利祖马布加贝瓦齐祖马布 (AB) 是一个关键的治疗方案,正在评估其将无法切除的HCC转化为可治愈状态的潜力.
- 了解反应模式和转化率对于优化HCC治疗策略至关重要.
研究的目的:
- 评估接受非治愈性意向治疗的肝细胞癌 (HCC) 患者对阿特佐利祖马布加贝瓦齐祖马布 (AB) 治疗的流行病学反应模式.
- 确定第一线治疗后潜在转化 (PC) 和实际转化 (AC) 到治愈治疗的比率.
- 调查低转换 (UC) 现象并确定影响它的因素.
主要方法:
- 一种元分析方法被用来分析来自48个国际中心的汇总数据.
- 该研究包括2,379名患有HCC的患者,从2019年到2023年接受一线非治愈性阿特佐利祖马布加贝瓦西祖马布 (AB) 或伦瓦提尼布 (LENV) 治疗.
- 主要终点包括客观响应 (OR),潜在转换 (PC),实际转换 (AC) 和转换不足 (UC) 率.
主要成果:
- 与伦瓦丁尼布 (LENV) 相比,阿特佐利祖马布加贝瓦齐祖马布 (AB) 的客观响应率 (29%) 和潜在转化率 (16%) 较高 (分别为24%和13%).
- 实际转换率 (AC) 对于两种治疗方法都很低,而且相似 (3%),表明转换率 (UC) 显著低 (40%为AB,36%为LENV).
- 在AB之后实现治愈转换的患者的3年生存率高达93%.
结论:
- 尽管AB的响应率和潜在转化率更高,但实际的治疗转化率仍然很低,这突出了现实世界HCC治疗中令人担忧的转化不足现象.
- 这项研究表明,基于新型免疫疗法的组合,虽然可以改善初始反应,但可能不会导致成功治愈转化率显著提高.
- 需要进一步的研究来了解和解决HCC患者治疗全身疗法的实际治愈转化障碍.

Tumor Immunotherapy
1.7K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Treatment Resistant Cancers
3.7K
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...
