RESUMO

PURPOSE: To compare the hematopoietic recovery and the clinical outcome after high dose chemotherapy and peripheral blood stem cell (PBSC) transplant between patients who received recombinant granulocyte colony-stimulating factor (G-CSF) starting on day 0 and those who received it starting on day +7. PATIENTS AND METHODS: Thirty-five consecutive patients received high dose chemotherapy with ifosfamide, etoposide and carboplatin (ICE) and autologous PBSC transplant. PBSC mobilization was achieved with G-CSF. In 19 transplants done in 1994, G-CSF was started on day 0 and in 16 procedures done in 1995, G-CSF was started on day +7. In both groups G-CSF was given until the absolute neutrophil count was 1 x 10(9)/L. RESULTS: The median number of days to reach an absolute neutrophil count > 0.1 x 10(9)/L, was 11 in the patients who started the G-CSF on day 0 and 11 days in the patients with delayed administration of G-CSF and to reach > 0.5 x 10(9)/L 14 days and 13 respectively. The median number of days to reach a platelet count > 20 x 10(9)/L was 14 and 13. Comparison of early vs. delayed administration of G-CSF did not show any significant differences regarding the time to achieve platelet independence, number of days with fever, median days of hospital stay, number of red cell or platelet transfusions. CONCLUSIONS: Starting G-CSF on day +7 after high dose ICE chemotherapy and autologous transplant of PBSC is as effective in restoring the hematopoietic function as is starting its administration on day 0.

RESUMO

BACKGROUND: Hematopoietic stem cell transplants are an accepted treatment for several malignant and nonmalignant hematologic diseases. Recently, the peripheral blood, after mobilization of stem cells with growth factors, has become the source of choice for hematopoietic stem cells. We report on a series of patients who received peripheral blood stem cell transplants at the Instituto Nacional de Cancerologia (INCAN) in Mexico City. METHODS: Between May 1995 and December 1999, 33 patients received peripheral blood stem cell transplants to treat hematologic diseases. Sixty percent of our patients had chronic myelocytic leukemia (CML). All had a matched related donor. Patients were conditioned with one of five different conditioning regimens and subsequently received one of two different graft-vs.-host disease prophylaxis regimens. Stratified Wilcoxon rank-sum, chi square, and Mann-Whitney tests were used to analyze the results. RESULTS: In our series, median time to achieve a total neutrophil count of 0.5 x 10(9)/L was 14 days and to achieve a platelet count of 20 x 10(9)/L, 15 days. Acute graft-vs.-host disease occurred in seven patients. Chronic graft-vs.-host disease occurred in 69% of surviving patients. Survival for low-risk patients was 67% and for the high-risk group, 9%. CONCLUSIONS: Peripheral blood stem cells produce a faster hematopoietic recovery. The rate of acute graft-vs.-host disease is not increased using the peripheral blood as source of stem cells; however, chronic graft-vs.-host disease continues to be a significant problem. Donors tolerated the procurement procedure without complications.

RESUMO

Se presenta el caso de un paciente con anemia de Fanconi quien a pesa de tener datos clínicos característicos del padecimiento, no fue diagnosticado sino hasta la edad de 30 años, y sólo posteriormente al establecimiento de aplasia medular. Además de la aplasia medular y de algunos defectos característicos tales como hipoplasia de los pulgares, el paciente presentaba diabetes mellitus e hipogonadismo, que parecen ser complicaciones poco frecuentes de esta enfermedad, aunque relacionadas con ellas. El propósito de este trabajo es describir el caso y mostrar los criterios de diagnósticos clínico y de laboratorio, haciendo énfasis en los estudios citogenéticos
