Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

5.8K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Cancer Survival Analysis01:21

Cancer Survival Analysis

590
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:

  • Oncology
  • Medical Informatics
  • Health Services Research

Background:

  • Colorectal cancer is a leading cancer in Germany, necessitating high-quality, evidence-based treatment.
  • Clinical guidelines are crucial for cancer care quality, but their real-world impact requires efficient knowledge delivery.
  • Timely access to guideline information at the point of care is essential for effective cancer treatment.

Purpose of the Study:

  • To create machine-readable clinical algorithms for colon and rectal cancer, annotated with Unified Medical Language System (UMLS) terms.
  • To develop an open-source workflow system for mapping patient data to these algorithms for guideline-based therapy recommendations.
  • To enhance the practical application of clinical guidelines in patient care.

Main Methods:

  • Developed rule-based clinical algorithms from established guidelines, using Business Process Model and Notation (BPMN).
  • Annotated algorithms with UMLS terminologies for machine readability.
  • Validated algorithms using manually extracted clinical data from 175 colorectal cancer patients.

Main Results:

  • Achieved high precision (87.64% colon, 84.70% rectal) and recall (87.64% colon, 83.72% rectal) for treatment pathway mapping.
  • Demonstrated that simpler algorithms with fewer decision points yield higher accuracy.
  • Successfully positioned patients on treatment pathways based on their tumor stage.

Conclusions:

  • The developed system enables automatic patient positioning on treatment decision pathways.
  • This approach facilitates guideline-based therapy recommendations at the point of care.
  • Accuracy is influenced by the complexity of the clinical algorithm and tumor stage.
