SOLID TUMORS
The E2C2 trial is population based; all patients receiving care for solid tumors from the included clinicians at any of the study sites are included in the study sample irrespective of cancer type or stage. At 4 sites, patients with malignant hematology are also included. For aims 1 and 2, we will test separate hypotheses for the main cohort and for the subset of the cohort with at least one elevated symptom score at some point.
