One of the possible drawbacks to autologous stem cell transplantation in breast cancer (BC) patients is the potential for tumor contamination in the transplanted product. We present a patient with advanced disease who received high-dose chemotherapy (HDC) and PBPC support as consolidation therapy after achieving complete remission with standard-dose first-line treatment, and suffered recurrence of the disease 6 months after transplantation. Retrospective analysis revealed the presence of contaminating cells in the leukapheretic product, and clinical evidence suggested a role for these cells in the tumor relapse.
