Possible Late Relapse of Diffuse Large BCell Lymphoma

Just wondering if there is anyone out there who may have had a diagnosis of "Late" Relapse following a 7 year remission from Non-Hodgkins DLBCL, originally presenting with a small bowel tumor (obstruction) and subsequent diagnosis of the DLBCL. If so, I'm curious as to whether or not a follow-up blood draw (after full remission 7 years prior) indicated the co-existence of a higher percentage (35%) of Absolute CD20 and CD19 proteins on their B-cells.
