Volumetric Tumor Analysis for Breast Cancer

Goal

Goal is to accommodate basic RECIST assessment for breast cancer (Response Evaluation Criteria In Solid Tumors). (RECIST is a set of published rules that define when cancer patients improve ("respond"), stay the same ("stable") or worsen ("progression") during treatments).

  • Determine features that currently exist in Slicer
  • Develop features that don't
  • Provide a framework that knits features together in a comfortable workflow.

Linear Measurements

  • Scroll through baseline
  • Find the tumor's longest diameter (no reformat, just on orig acquisition)
  • Measure the longest diameter D1(t1)
  • Measure the orthogonal diameter D2(t1)
  • If there are multiple tumors, measure both diams in each tumor and sum to get relative D1(t1) and relative D2(t1)
  • Perform same measurements D1(t2) and D2(t2)
  • Specific results to report:
    • Percent change
    • Absolute change
    • Question: units for these values -- mm^2?
