Abstract

The main aims for preparative regimens in BMT/PBPCT are malignant cell eradication and/or immunosupresion to facilitate engraftment. TBI is used in concert with cyclophospamide (Cy) to increase activity.

In our Unit two TBI + Cy conditioned allotransplantations – (1) BMT and (2) PBPCT – have been performed. Patients – (1) 7 years and (2) 10 years old, males, suffering from: (1) ALL – second and (2) ALL – fourth remission, received transplant material from HLA identical siblings. Transplant preparative regimens consisted of TBI (Co-60 + electrons 6 and 9 MeV: 12–16 Gy. performed in Greatpoland Cancer Centre, Poznań) and Cy (200 mg/kg bw). Patients received routine decontamination for infection prevention. Heparine for VOD and Cyclosporine + MTX for GvHD prophylaxis. Treatment related toxicity was judged accordind to WHO scale, standard criteria were used for GvHD grading.

Both patients were Hepatitis B virus positive, patient (2) was also HCV + before treatment. Hematological recovery was observed in both patient (1) 13 and (2) 10 days after transplantation. Toxicity in patient (1) was WHO-1 for the liver and WHO-1 for kidneys. There was no skin or mucosal toxicity. Patient (2) had WHO-2 GIT mucosa and WHO-3 liver toxicities on day +15. No skin toxicity was observed. On day +16 patient(2) rapidly developed signs of pulmonary complications further followed by CNS involvement. He required artificial ventilation. No aGvHD observed. Patient died on day +31. Patient (1) is alive and well +36 days after transplantation. aGvHD grade I (skin) was observed on day +25 after transplantation and responded well to glukokorticosteroid therapy (2mg/kg for 5 days).

The post-transplant history of these two cases reflects on possible complications of BMT/PBPCT with TBI.
