Area of Science:

Medical informatics
Computational oncology
Natural Language Processing

Background:

Accurate primary tumor diagnosis is crucial for patients undergoing stereotactic radiosurgery (SRS).
Existing methods using International Classification of Diseases (ICD) codes lack the necessary detail, especially for metastatic cancers.
Electronic health records (EHRs) contain valuable diagnostic information but are challenging to extract accurately.

Purpose of the Study:

To develop and evaluate a Natural Language Processing (NLP) approach for precise primary tumor histology extraction from EHRs.
To improve upon the limitations of ICD coding for detailed tumor classification in SRS patients.
To enhance the identification of specific histology subtypes not captured by ICD-10 CM.

Main Methods:

Utilizing advanced NLP algorithms for text analysis of patient EHRs.
Manual annotation of patient data to train and validate the NLP models.
Developing algorithms for accurate primary tumor type and histology subtype classification.

Main Results:

Achieved significant improvements in the accuracy of primary tumor classification.
Demonstrated enhanced efficiency in extracting detailed tumor histology.
Successfully identified histology subtypes beyond the granularity offered by ICD-10 CM codes.

Conclusions:

NLP offers a valuable tool for refining research processes in oncology.
Improved patient cohort identification for research and clinical trials.
Potential to enhance operational efficiencies and ultimately improve patient outcomes in SRS treatment.
