ReviewRituximab: enhancing stem cell transplantation in mantle cell lymphoma.
Mantle cell lymphoma (MCL) responds poorly to standard chemotherapy regimens used in non-Hodgkin's lymphoma. As a result, a combination of high-dose chemotherapy (HDT) with autologous stem cell transplantation (ASCT) is being investigated in patients with MCL. So far, however, there is no evidence for long-term remission -- believed, in part, to be due to contamination of the transfusion product with residual cancer cells. ⋯ PCR analyses of the bone marrow following the four-step high-dose regimen with purging and transplantation showed that all patients achieved molecular remission. After a median follow-up of 22 months (range 10-42 months), two patients had died while 26 were alive and disease free. This method allows efficient in vivo purging in the context of an effective chemotherapy regimen and may have a role as first-line therapy in MCL patients who respond poorly to standard treatment.

The role of biomedical and psychosocial factors for the prediction of pain and distress in patients undergoing high-dose therapy and BMT/PBSCT.
Recent research has shown that cancer patients undergoing bone marrow transplantation (BMT) experience moderate to severe mouth pain due to treatment-related mucositis in spite of morphine therapy. Treatment-related emotional distress in BMT patients is also described widely. This study examined several biomedical, psychological and social variables as possible predictors for the intensity of treatment-related mouth pain and anxious mood in 63 cancer patients undergoing BMT or stem cell transplantation (SCT) within a prospective longitudinal design. ⋯ Among the biomedical variables mucositis was most strongly related to mouth pain besides mode of transplantation, risk, TBI and age. Among the psychological variables BMT-related distress was the most important predictor, with resources in private life or at work and pain-related coping modes as further significant predictors. These results imply that relevant predictors should be assessed as high risk factors for an increased vulnerability for treatment-related side-effects before treatment starts indicating an additional offer of psychological treatment in high risk patients.

CsA-based post-graft immunosuppression: the main factor for improving outcome of allografted patients with acquired aplastic anemia. A retrospective survey by the Spanish Group of Hematopoietic Transplantation.
A retrospective multicenter study was performed to assess the clinical results in patients with acquired aplastic anemia (AA) allografted over a 19 year period and to identify prognostic factors influencing survival. From April 1978 to December 1997, 176 patients were transplanted. Records from 160 receiving related matched bone marrow transplantation (BMT) were reviewed. ⋯ Survival achieved since 1991 is 79.79%, and graft failure and acute severe GVHD rates are 6.0% and 11.8%, respectively. In conclusion, CsA-based post-graft immunosuppression has been crucial in achieving improved survival in patients with acquired AA up to 40 years of age. Regardless of CsA use, further improvement in survival was apparent with time, probably due to better skills in patient care.

Respiratory syncytial virus infection following hematopoietic stem cell transplantation.
Respiratory syncytial virus, one of the most common causes of respiratory infections in immunocompetent individuals, is frequently spread to recipients of HSCT by family members, other patients, and health care workers. In immunosuppressed individuals, progression from upper respiratory tract disease to pneumonia is common, and usually fatal if left untreated. We performed a retrospective analysis of RSV infections in recipients of autologous or allogeneic transplants. ⋯ Of the 58 patients with an RSV infection, 16 of 21 patients identified within the first post-transplant month, developed pneumonia. Seventy-two percent of patients received aerosolized ribavirin and/or RSV-IGIV, including 23 of 25 patients diagnosed with RSV pneumonia. In this aggressively treated patient population, three patients died of RSV disease, each following an unrelated HSCT.
