- 为了比较从功能性避免治疗与历史控制数据的PRO.
- 评估功能性回避对患者生活质量的影响.
主要方法:
- 患有局部晚期肺癌的患者接受了治疗意图的化疗辐射.
- 4DCT-通风成像指导了功能性回避治疗计划的创建.
- 使用FACT-L,EQ-5D和EQ-VAS收集PROs,并与RTOG 0617和PACIFIC试验数据进行比较.
主要成果:
- 在RTOG 0617试验中的47%的患者在FACT-TOI中经历了显著的下降,而在功能性避开组 (P=.03) 中,这一比例为26.8%.
- 与PACIFIC队列 (1.6 ± 0.6;P=.012) 相比,功能回避队列在12个月后显示了EQ-VAS得分的显著更高的变化 (9.9 ± 3.3).
- 59名患者完成了基线PRO调查,平均年龄为65岁,83%被诊断为非小细胞肺癌.
结论:
- 使用4DCT通风的II阶段功能回避在特定子尺度 (FACT-TOI,EQ-VAS) 中证明了改善的PROs.

01:21Cancer Survival Analysis
334
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...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

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...
