CHOP-21 for the treatment of post-transplant lymphoproliferative disorders (PTLD) following solid organ transplantation.

There is no definitive treatment for post-transplant lymphoproliferative disorder (PTLD) that does not respond to reduction of immunosuppression. With a median follow-up of 8.8 years, the current retrospective analysis of standard CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) in 26 adults with PTLD demonstrated an overall response rate of 65% and median overall and progression-free survivals of 13.9 and 42 months, respectively.
