对e-RT计划的评估 (VMAT与3D-CRT对比).
对i-RT计划的评估 (3D-BT与2D-BT).

主要成果:

与3D-CRT相比,VMAT证明了优越的剂量覆盖率和关键器官保护.
VMAT显著降低了直肠剂量 (43.5 Gy vs. 48.6 Gy) 和输送到小肠的剂量 (47.6 Gy).
与2D-BT相比,3D-BT显著降低了直肠剂量 (63.1 Gy vs. 49.9 Gy)

结论:

在妇科癌症的外部光束放射治疗中,VMAT优于3D-CRT.
对于内部光束放射治疗,3D-BT比2D-BT更好,因为结果更好.
这些先进的技术提高了治疗效率和患者安全.

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...

Comparing the Survival Analysis of Two or More Groups

Comparing the Survival Analysis of Two or More Groups

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...
