Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
The Overall Response Rate [Complete Response (CR) + Partial Response (PR)] Determined on the Basis of Revised Response Criteria for Malignant Lymphoma
Periodo de tiempo: up to 30 weeks

CR: Disappearance of all evidence of disease. PR: Regression of measurable disease and no new sites.

For the criteria for CR, See Outcome measure 2 description.

The criteria for PR is as below.

Nodal Masses:

more than 50% decrease in sum of the product of the perpendicular diameters (SPD) of up to 6 largest dominant masses; no increase in size of other nodes

  1. FDG-avid or PET positive prior to therapy; one or more PET positive at previously involved site
  2. Variably FDG-avid or PET negative; regression on CT

Spleen, Liver:

more than 50% decrease in SPD of nodules (for single nodule in greatest transverse diameter); no increase in size of liver or spleen

Bone Marrow:

Irrelevant if positive prior to therapy; cell type should be specified
up to 30 weeks
