Veno-occlusive disease (VOD) of the liver and pulmonary drug toxicity (PDT) are two major complications of high-dose chemotherapy and autologous bone marrow transplantation (BMT) for solid tumors. We have previously demonstrated that an elevated plasma TGF-beta concentration before transplant predicts the later occurrence of these complications. In the present study, we used a simplified enzyme-linked immunosorbant assay (ELISA) to prospectively evaluate the kinetics of plasma TGF-beta concentrations of 45 patients with stage II breast cancer who underwent high-dose chemotherapy and autologous BMT. We demonstrated that, of the three TGF-beta isoforms, only TGF-beta 1 was present in the plasma. Pre-transplant plasma TGF-beta 1 was significantly higher in patients with VOD and PDT compared with that in patients without these complications. The plasma TGF-beta 1 level in patients who later developed VOD or PDT decreased to that of controls within 2 days of initiating high-dose chemotherapy; this decrease was not correlated with platelet concentration changes. These results suggest that interventions aimed at preventing the development at VOD or PDT must be given early in the course of high-dose chemotherapy. |
