Myeloablative hematopoietic stem cell transplantation for myelodysplastic syndrome in patients younger than 55 years: impact of comorbidity and disease burden on the long-term outcome

INTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 2 2010

Summary We retrospectively investigated 31 myelodysplastic syndrome (MDS) patients receiving myeloablative hematopoietic stem cell transplantation (HCT) and focused on prognostic factors affecting the long-term outcome. Patients were classified according to the French-American-British classification and the HCT-comorbidity index was determined. Cytosine arabinoside or thiotepa combined with cyclophosphamide and total body irradiation was used as myeloablative conditioning in eight and 23 patients respectively. After a follow-up period of 0.8,14.2 years from transplantation (median: 6.4 years), 23 patients were alive in complete remission, and the 5-year overall survival (OS) and disease-free survival (DFS) rates were 79% and 72% respectively. The cumulative nonrelapse mortality (NRM) rate was 22% at 5 years. According to multivariate analysis, ,20% blasts in the bone marrow and an HCT-comorbidity score , 3 were significantly associated with poor OS and DFS. Patients with a high HCT-comorbidity score and male patients receiving transplantation from female donors were significantly more likely to have a higher NRM according to the univariate, but not the multivariate analysis. These data suggest that comorbidity and the tumor burden at the time of transplantation may be useful variables for predicting the outcome in MDS patients receiving myeloablative HCT. [source]


Diffuse large B-cell lymphoma

CANCER, Issue 21 2009
Clinical characterization, prognosis of Waldeyer ring versus lymph node presentation
Abstract BACKGROUND: The objective of this study was to compare the clinical features and prognosis of patients with diffuse large B-cell lymphoma (DLBCL) of Waldeyer ring (WR-DLBCL) and patients with lymph node DLBCL (N-DLBCL). METHODS: One hundred eighty-one patients with WR-DLBCL and N-DLBCL were reviewed. There were 57 patients with stage I disease, 83 patients with stage II disease, 26 patients with stage III disease, and 15 patients with stage IV disease. Among them, 101 patients had primary N-DLBCL, and 80 patients had primary WR-DLBCL. RESULTS: Patients with WR-DLBCL and N-DLBCL usually presented at an older age and had localized disease, a low frequency of B symptoms, a good performance status, and a low-risk International Prognostic Index (IPI) score. Compared with patients who had N-DLBCL, patients who had WR-DLBCL presented with more stage II disease and lower tumor burdens. The overall response rate after treatment was similar in both groups. The 5-year overall survival (OS) and progression-free survival (PFS) rates were 76% and 61% in patients with WR-DLBCL, respectively, and 56% and 50% in patients with N-DLBCL, respectively (P = .119 for OS; P = .052 for PFS). IPI scores and elevated ,2-microglobulin and LDH levels were associated with a poor prognosis for patients who had WR-DLBCL; whereas bulky tumor, elevated ,2-microglobulin levels, and IPI scores were associated with poor OS for patients who had N-DLBCL. CONCLUSIONS: The current results supported the continued inclusion of WR-DLBCL as a lymph node group in the staging of DLBCL. Patients with WR-DLBCL had clinical features and prognosis similar to those of patients with N-DLBCL. Cancer 2009. © 2009 American Cancer Society. [source]


Hepatic artery chemoembolization for 110 gastrointestinal stromal tumors

CANCER, Issue 12 2006
Response, prognostic factors, survival
Abstract BACKGROUND. The efficacy of hepatic artery chemoembolization (HACE) was evaluated for gastrointestinal stromal tumors (GISTs) metastatic to the liver. METHODS. Records for patients with metastatic GIST who underwent HACE between January 1993 and March 2005 were reviewed and cross-sectional images were used to determine objective tumor response. Progression-free survival in the liver (PFS-liver) and overall survival (OS) were calculated with the Kaplan,Meier method. Patient, tumor, and treatment variables were analyzed to identify factors influencing survival. RESULTS. Of the 110 patients identified, the radiologic response to HACE could be evaluated in 85 patients, 12 of whom (14%) demonstrated partial responses, 63 of whom (74%) demonstrated stable disease, and 10 of whom (12%) demonstrated progressive disease. PFS-liver rates were 31.2%, 8.2%, and 5.4% at 1, 2, and 3 years, respectively; the median PFS time was 8.2 months. OS rates were 62% at 1 year, 32% at 2 years, and 20% at 3 years; the median OS time was 17.2 months. Patients who had >5 liver metastases and received only 1 HACE treatment were found to have a shorter PFS compared with patients with fewer metastases or those who received ,2 HACE sessions. Extensive liver involvement, the presence of extrahepatic metastases, and progression of liver disease after HACE were associated with poor OS. Use of imatinib prolonged OS time. CONCLUSIONS. HACE produced a durable tumor response or disease stabilization in the majority of patients with GISTs metastatic to liver. Extent of liver disease, presence of extrahepatic disease, number of embolization treatments, and use of imatinib were found to have prognostic influence on PFS, OS, or both.

Complex of urokinase-type plasminogen activator with its type 1 inhibitor predicts poor outcome in 576 patients with lymph node,negative breast carcinoma

CANCER, Issue 3 2004

Abstract BACKGROUND The ability of a solid tumor to grow and metastasize has a significant dependence on protease systems, such as the plasminogen activation system. The plasminogen activation system includes the urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor type 1 (PAI-1), among other molecules. Both uPA and PAI-1 are established prognostic factors for patients with breast carcinoma. In the current study, the authors investigated whether the complex of uPA with PAI-1 is also associated with the natural course of this malignancy. METHODS Cytosolic levels of uPA, PAI-1, and the uPA:PAI-1 complex were measured in tumor tissue from 576 patients with lymph node,negative invasive breast carcinoma using quantitative enzyme-linked immunosorbent assays. Patients did not receive adjuvant systemic therapy, and the median follow-up duration was 61 months (range, 2,187 months) after primary diagnosis. Correlations with well known clinicopathologic factors were assessed, and univariate and multivariate survival analyses were performed. RESULTS uPA:PAI-1 complex levels were positively associated with adverse histologic grade and inversely correlated with estrogen and progesterone receptor status. On univariate analysis, increased levels of the uPA:PAI-1 complex were found to be associated with reduced recurrence-free survival (RFS) and overall survival (OS) rates. On multivariate analysis, uPA:PAI-1 complex levels were found to be an independent predictor of OS (P = 0.039), but not RFS (P = 0.240). When uPA and PAI-1 levels were not included in the multivariate analysis, uPA:PAI-1 complex levels became a significant predictor of both RFS and OS (P = 0.029 and P = 0.007, respectively). CONCLUSIONS The results of the current study demonstrate that uPA:PAI-1 complex levels have prognostic value on univariate analysis. In addition, increased uPA:PAI-1 complex levels were significantly associated with poor OS on multivariate analysis. Increased uPA:PAI-1 complex levels were also significantly associated with reduced RFS rates after the exclusion of uPA and PAI-1 levels from the multivariate analysis model.
