Description
This model extracts entities related to the patient”s response to the oncology treatment, including clinical response and changes in tumor size.
Definitions of Predicted Entities:
Line_Of_Therapy: Explicit references to the line of therapy of an oncological therapy (e.g. “first-line treatment”).Response_To_Treatment: Terms related to clinical progress of the patient related to cancer treatment, including “recurrence”, “bad response” or “improvement”.Size_Trend: Terms related to the changes in the size of the tumor (such as “growth” or “reduced in size”).
Predicted Entities
Line_Of_Therapy, Response_To_Treatment, Size_Trend
