CS Tumor Size/Ext Eval

This input is used for staging

Notes

**Note**: According to AJCC, "The use of the term pathologic staging is reserved for patients who undergo staging laparotomy with an explicit intent to assess the presence of abdominal disease or to define histologic microscopic disease extent in the abdomen. Staging laparotomy and pathological staging have been essentially abandoned as useful procedures." (7th ed., page 610) Therefore, Collaborative Staging uses a modified evaluation scheme for lymphomas, and it applies to the CS Tumor Size/Ext-Eval field only. The other Eval fields are coded as "not applicable" for this schema.
