Management of neoplastic pericardial effusions.

AIMS AND BACKGROUND: Malignant pericardial effusion and cardiac tamponade are known complications of many advanced malignancies such as breast cancer, lung cancer, lymphomas and leukemias. Overall survival is low, due to other metastatic localizations. The present study evaluated the clinical outcome and prognosis in patients with advanced cancer with pericardial effusion. METHODS: We studied 7 patients, 4 men and 3 women, with malignant pericardial effusion, affected by breast cancer (2 patients), lung cancer (adenocarcinoma in 3 patients, microcytoma in 1 patient), and B-cell non-Hodgkin lymphoma (1 patient). All patients underwent pericardiocentesis; 3 patients underwent an instillation of thiotepa. RESULTS: One terminal patient treated with pericardiocentesis died after only a few hours. All the remaining patients experienced immediate symptomatic improvement and no operative complications. At the end of the study period, 2 patients were alive at 59 and 33 months, respectively, and 4 died of disease progression at 1 to 32 months (mean, 10.5). CONCLUSIONS: Pericardiocentesis is an active necessary approach, and intrapericardial treatment with thiotepa was able to reduce pericardial effusion and to prevent its reaccumulation. The standard treatment of malignant effusion and cardiac tamponade has not yet been defined. Physicians should consider the status and the prognosis of each case.

Melphalan, prednisone, and lenalidomide for newly diagnosed myeloma: kinetics of neutropenia and thrombocytopenia and time-to-event results.

BACKGROUND: Initial analysis of the combination melphalan, prednisone, plus lenalidomide (MPR) showed significant antimyeloma activity in patients with untreated multiple myeloma, with neutropenia and thrombocytopenia as the most frequent side effects. This updated analysis reassessed the kinetics of neutropenia and thrombocytopenia as well as the safety and efficacy of MPR. PATIENTS AND METHODS: A total of 21 patients with newly diagnosed myeloma received melphalan 0.18 mg/kg on days 1-4, prednisone 2 mg/kg on days 1-4, and lenalidomide 10 mg daily on days 1-21 for nine 28-day cycles, followed by maintenance therapy with lenalidomide 10 mg daily on days 1-21. RESULTS: Grade 3/4 neutropenia occurred in 52% of the patients, and granulocyte colonystimulating factor was administered in 43%. The mean neutrophil counts at the start of each MPR cycle, during nadir, and after 6 months of maintenance were 2.69 x 109/L, 1.43 x 109/L, and 2.11 x 109/L, respectively. Grade 3/4 thrombocytopenia occurred in 24% of the patients. Platelet transfusions were required by 1 patient (5%) with a platelet count of 16 x 109/L; however, no thrombocytopenia-associated bleeding was reported. The mean platelet counts at the start of each cycle, during nadir, and after 6 months of maintenance were 174 x 109/L, 121 x 109/L, and 158 x 109/L, respectively. Median follow-up was 29.6 months, median progression-free survival was 28.5 months, and 2-year overall survival was 91%. CONCLUSION: MPR is a promising regimen with manageable hematologic toxicity.

[Pure red cell aplasia in patient affected by myelodysplastic syndrome treated with R-Epo]. / Aplasia eritroide pura in un paziente con anemia refrattaria in trattamento con eritropoietina ricombinante.

Pure red cell aplasia (PRCA) is a rare condition described in patients with chronic kidney disease during alpha-Epo treatment subcutaneous administered generated by anti-R-Epo antibodies. Recently two cases of PRCA have been reported in patients affected by myelodysplastic syndrome treated with R-Epo. We described one more case of PRCA in a patient with refractory anemia treated with R-Epo.

The VAD-DCEP sequence is an effective pre-transplant therapy in untreated multiple myeloma.

BACKGROUND AND OBJECTIVES: Standard treatment for patients with multiple myeloma is debulking chemotherapy with non-alkylating agents followed by a regimen to mobilize peripheral blood stem cells (PBSC) and the transplantation of the mobilized, autologous PBSC. The aim of this study was to evaluate the efficacy of a new regimen and compare it with that of a previous regimen. DESIGN AND METHODS: In a large cohort of 106 patients (group I) we administered a new pre-transplant program which includes 2 courses of pulsed-VAD (vincristine, adriamycin, dexamethasone) followed by 2 courses of DCEP (dexamethasone, cyclophosphamide, etoposide and cis-platinum). We compared the efficacy of this new VAD-DCEP sequence, in terms of mobilizing capacity, toxicity and anti-myeloma activity in comparison with that of the previous VAD-high-dose cyclophosphamide program (group II, 40 patients). RESULTS: In group I 81/106 (76.4%) patients yielded >or= 4x10(6)/kg CD34+ cells, as did 30/40 (75%) in group II but with a significantly higher toxicity in this latter group. In detail, 9 patients in group I (8.5%) had WHO grade III neutropenia versus 35 in group II (87.5%), 5 patients of group I (4.7%) had grade III thrombocytopenia versus 12 patients in group II (30%), and 8 patients in group I (7.5%) experienced an infections fever versus 9 patients in group II (22.5%). Therefore, nearly all patients in group II had to be admitted to hospital (39/40, 97.5%). There was a higher percentage of responses (CR+VGPR+PR) in group I than in group II: 73% versus 50% (p=0.02). INTERPRETATION AND CONCLUSIONS: the VAD-DCEP sequence has an adequate mobilizing capacity, without significant toxicity, and a good anti-myeloma activity, and therefore represents a safe and effective therapeutic approach for multiple myeloma patients at the onset of their disease.

A clonal T cell population in peripheral blood of patients with multiple myeloma and chronic lymphocytic leukemia has recently been observed. We describe a 73 years old woman with B cell lymphoma who presented a clonal T cell population in peripheral blood and bone marrow.
