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...

Area of Science:

Medical Physics
Radiotherapy
Computational Biology

Background:

Complexity metrics quantify radiotherapy treatment plan aspects influencing deliverability and accuracy.
A lack of standardized tools hinders the extraction and application of these metrics.
Radiotherapy treatment planning complexity requires robust quantification methods.

Purpose of the Study:

Introduce UCoMX (Universal Complexity Metrics Extractor), a novel software package.
Enable automated extraction of complexity metrics from DICOM-RT plan files.
Provide a universal solution for radiotherapy plan complexity analysis.

Main Methods:

Developed UCoMX with VCoMX (VMAT/IMRT) and TCoMX (Helical Tomotherapy) extraction engines.
Implemented over 90 complexity metrics from existing literature.
Created freely available Matlab-based and stand-alone software versions.

Main Results:

UCoMX processes DICOM-RT plan files from major commercial Treatment Planning Systems (TPSs).
The package supports VMAT, IMRT, and Helical Tomotherapy plans.
A reference dataset is provided for inter-center comparisons.

Conclusions:

UCoMX provides a user-friendly solution for radiotherapy plan complexity metric extraction.
The software's versatility is supported by multiple versions and broad TPS compatibility.
UCoMX empowers researchers with an efficient, free tool for treatment plan complexity computation.
