Patients with multiple myeloma transplanted with increased numbers of pbpc demonstrate early recovery of total lymphocytes

Patients with multiple myeloma (MM) are currently treated with autologous peripheral blood cell transplantation (PBCT). In most cases infusion of 5 x 10° CD34+ cells/kg is associated with timely engraftment of platelets and neutrophils. In some patients a much higher number of stem cells can be harvested. To assess the effects of infusing high doses of CD34+ progenitors we evaluated patients undergoing PBCT for MM between 10/97 and 6/ 00. …
