Chronic Lymphocytic Leukemia Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Treatment Option Overview


About 1% of morphologic CLL cases express T-cell markers (CD4 and CD7) and have clonal rearrangements of their T-cell receptor genes. These patients have a higher frequency of skin lesions, more variable lymphocyte shape, and shorter median survival (13 months) with minimal responses to chemotherapy.[13]

Computed tomographic (CT) scans have a very limited role in following patients after completion of treatment; the decision to treat for relapse was determined by CT scan or ultrasound in only 2 of 176 patients in 3 prospective trials for the German CLL Study Group.[14]
