概括
性细胞癌 (PRCC) 的病理亚型表现出局部和中央审查之间的一致性较低. 这种亚型并没有确定哪些患者会从卡博赞提尼布治疗中获益更多.
科学领域:
- 在瘤学瘤学.
- 病理学 病理学 病理学
- 临床试验 临床试验
背景情况:
- 乳头细胞癌 (PRCC) 是癌的一个亚型.
- PRCC可以进一步分为1型和2型,它们可能具有不同的临床行为和对治疗的反应.
- 准确的病理亚型是指导高级耐火PRCC治疗决策的关键.
研究的目的:
- 在接受向治疗的患者中,评估PRCC亚型 (1型与2型) 的临床意义.
- 评估PRCC亚型的局部病理学审查的一致性,敏感性和积极预测值 (PPV).
- 为了确定PRCC亚型是否可以识别患者亚组,这些患者更受益于特定的向疗法,如卡博桑提尼布.
主要方法:
- 患有晚期耐火性PRCC的患者被随机分配给sunitinib或cabozantinib.
- 通过局部病理学审查确定PRCC亚型 (类型1,类型2,NOS/混合),并由专家生殖尿路病理学家进行中央审查.
- 分析了敏感性,局部审查的PPV,客观反应率 (ORR) 和无进展生存期 (PFS),根据中央审查分层按亚型分层.
主要成果:
- 在本地和中央审查中,亚型的患病率有所不同 (例如,类型1:17.7%与29.3%).
- 局部病理学审查显示,所有亚型 (类型 1:48%,类型 2:67%,NOS/混合:43%) 和可变PPVs的敏感性低.
- 与sunitinib相比,cabozantinib在1型和2型PRCC亚组中表现出改善的PFS和ORR,但亚型对响应者没有丰富.
结论:
- 在地方和中央PRCC亚型审查之间存在显著的不一致.
- 通过局部病理学审查来确定PRCC的亚型在预测针对性治疗的治疗反应方面具有有限的临床价值.
- 这些发现与最近的世卫组织2022年指导方针一致,表明PRCC病理亚型在转移性疾病管理中的有用性有限.

Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Cancer Survival Analysis
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
