MTX withdrawal and observation for a short period should be considered in the initial management of patients who develop LPD while on MTX therapy. Responses were consistently observed, but not limited to patients in whom EBV was detected by ISHS or PCR. Further studies are required to confirm these findings and to evaluate the role for EBV in LPD that occur in patients receiving MTX.
In patients cured by initial treatment for Hodgkin's disease, RT was associated with a statistically significant increase in STs, particularly lung cancer. CMT was not associated with a significant increase in STs. These data may have important implications for the design of newer therapies for early-stage Hodgkin's disease.
Summary:A retrospective analysis was performed on 100 patients with non-Hodgkin's lymphoma (NHL, n = 75) or Hodgkin's disease (HD, n = 25) who underwent peripheral blood progenitor cell transplant (PBPCT) following high-dose chemotherapy (HDCT) with BCNU, etoposide, cytarabine and melphalan (BEAM) between March 1994 and June 1997. Following PBPCT and until engraftment all patients received oral ciprofloxacin and fluconazole, patients with positive Herpes simplex virus serology received acyclovir and 91 patients received filgrastim. The median days of neutropenia and days to an absolute neutrophil count (ANC) Ͼ500/mm 3 were 6 and 9, respectively. Febrile neutropenia occurred in 68 patients. Gram-positive bacteremia occurred in 14 patients. No gram-negative infections, invasive fungal infections, intensive care visits or deaths occurred during the period of neutropenia or in the first 30 days following transplant. In multivariate logistic regression the risk of development of any infection was associated only with the duration of neutropenia (P = 0.02) and the risk of bacteremia was associated only with the number of CD34+ cells infused (P = 0.046). Among 49 patients treated in the outpatient setting, 14 (28%) were never admitted. High-dose chemotherapy with BEAM supported by PBPCT, prophylactic antibiotics and filgrastim resulted in a low incidence of infections and no acute mortality. WBC engraftment occurred rapidly allowing for a predictable course during which lengthy hospital stays and amphotericin therapy could be avoided.
A positive 67Ga scan at the end of therapy is rarely seen in patients with Hodgkin's disease and should be considered a manifestation of gross residual disease. However, a negative 67Ga scan after therapy had a significantly lower predictive value in patients with stage III to IV disease compared with stage I to II disease. The predictive value of 67Ga scans, as well as newer imaging studies, should be analyzed according to pretreatment stage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
