概括

一个新的风险评分,PRETREAT,准确地预测了肝移植后周围胆管癌 (pCCA) 患者的移植后复发. 该工具有助于个性化监测和治疗策略,以改善患者的治疗结果.

科学领域:

肝胆道手术是肝胆道的手术.
移植瘤学移植瘤学
恶性瘤风险分层的分层.

背景情况:

周围胆管癌 (pCCA) 是具有不良预后的侵袭性.
肝移植 (LT) 与新辅助化学辐射 (CRT) 为选择的pCCA患者提供治疗方法.
在pCCA中缺乏针对LT后复发的风险分层工具.

研究的目的:

开发和验证一个风险评分,用于预测pCCA的移植后复发.
确定pCCA在LT后复发的关键预测因素.
将pCCA患者分为风险组进行分层,以便量身定制的管理.

主要方法:

对399名接受新辅助CRT和LT治疗的pCCA患者进行了回顾性研究.
多变量考克斯回归与LASSO用于预测因子的识别.
开发和验证PRETREAT风险评分 (内部和外部).

主要成果:

确定了4个独立的预测因素:残留瘤,血管封闭,淋巴血管入侵和瘤直径.
在PRETREAT评分中,差别表现出色 (C指数为0.83-0.85).
在低风险,中等风险和高风险组中,无复发的5年生存率存在显著差异 (89.0%,38.3%,15.4%).

结论:

PRETREAT评分是一个有价值的工具,用于对LT后的pCCA患者进行风险分层监测.
促进个性化管理,并指导未来的临床试验设计.
能够更好地预测复发,并为移植后护理策略提供信息.

Treatment Resistent Cancers

Treatment Resistent Cancers

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...

Cancer Survival Analysis

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...
