Stability of abnormal tumor immunophenotype of sequential samples from a SS patients undergoing treatment. There is stable expression of dim CD4 in the tumor cells, with CD7dim(+) and CD7bright(+) populations painted red and green, respectively. The histogram on the far right shows a decrease in the CD7dim(+) population in response to pentostatin therapy. No overall decreases in tumor cell number in response to the prior Targretin, interferon or photopheresis treatments were noted.
