Siro = sirolimus, VCR = vincristine
*p-value denotes comparison of Siro + Steroids to VCR + steroids only, Fisher’s exact test
HemR = hematologic response, in patients with KMP only (platelet count > 100,000/μl x 2 consecutive lab measurements without transfusion)
RadR = radiologic response (any measurable decrease in tumor size on radiographic imaging, if tumor measurements were available, the RECIST criteria for partial response was used)
ClinR = clinical response (resolution of symptoms, functional deficit, or decrease in size of tumor by visual inspection, even if not a complete response), radiologic response
