RESUMO
Although the deterioration in pulmonary functions is a well-known important problem due to the treatment of the Hodgkin's lymphoma patients, the immediate and long term effects of the therapy and its distinctive components were not shown clearly yet. We planned to investigate effects of multiple agent chemotherapy and/or radiotherapy to pulmonary functions immediately and thereafter and the possible effects of the managing this situation. 34 patients were included the study. The patients were evaluated for peak expiratory flow (PEF), forced expiratory volume in 1 s (FEV1), forced expiratory vital capacity (FVC), mean total lung capacity (TLC) values, FEV1/FVC ratio, diffusing capacity for carbonmonoxide (DLco), diffusing capacity for carbonmonoxide corrected for hemoglobin concentration (DLCO) before and at 1, 6 and 12 months after the initiation of the treatment. Demographic characteristics; disease stages; chemotherapy protocols; whether radiotherapy is received; if yes, the region and the dose received were recorded. The tests were finally analysed in two separated groups; group A treated with only chemotherapy and group B; treated with combination therapy, chemotherapy and radiotherapy. In group A, FVC and FEV1 is similar before and after treatment. FEV1/FVC ratio was increased (P = 0.0001) in this group despite increasing in mean TLC values (P = 0.001). No meaningful changes were observed in PEF and DLCO values in group A. In group B, FVC, FEV1 and PEF were decreased after treatment (for FVC P = 0.028, for FEV1 P = 0.04). Despite a decrease in first month of the treatment in FEV1/FVC ratio and DLco these two parameters were recovered at the end of the first year in group B patients. TLC values were increased after treatment in group B as in group A (P = 0.035). We believe that, if these patients are managed well in 1 year; necessary precautions are provided; and patients are well-informed, then there wouldn't be too much risk and mortality rate for long-term side effects of ABVD and mediastinal RT.
RESUMO
Autologous hematopoietic stem cell transplantation (auto-HSCT) provides hematopoietic support after high-dose chemotherapy and is the standard of care for patients with multiple myeloma (MM), chemo sensitive relapsed high or intermediate grade non-Hodgkin's lymphoma (NHL) and Hodgkin's lymphoma (HL). However, yields of hematopoietic stem cells vary greatly between patients, and the optimal strategy to mobilize hematopoietic stem cells into peripheral blood for collection has not been defined yet. We investigated the efficacy and safety of chemo mobilization with an intermediate dose etoposide (VP-16; 200 mg/m(2) on days 1-3) and granulocyte-colony stimulating factor (G-CSF)(5 µg/kg twice daily from day 4 through the final day of collection). We reviewed our institutional experience with 91 patients (71 MM, 12 HL, 8 NHL) mobilized with this regimen. VP-16 + G-CSF resulted in successful mobilization in 95.55% of the patients (on one patient stem cell collection with plerixafor was applied), including 76 patients (83.52%) whose stem cells were collected successfully in a single day. Collection was managed between min. D8 and max. D17. Patient age, gender, exposure to previous irradiation and chemotherapy, previous mobilization attempts, and disease characteristics were not considered during selection. Adverse effects of the regimen included supportive transfusions and fevers requiring hospitalization or intravenous antibiotics. VP-16 and G-CSF appears to be a safe and effective mobilization regimen for patients with multiple myeloma, non-Hodgkin's lymphoma and Hodgkin's lymphoma undergoing autologous stem cell transplantation, producing excellent stem cell yield with the majority of patients requiring 1 day of apheresis.
