Rapidly progressive organising pneumonia associated with cytomegalovirus infection in a patient with psoriasis.

2016

A 63-year-old woman experienced progressive respiratory distress and psoriatic plaques. The radiographic images showed diffuse interstitial infiltrates. The surgical open lung biopsy revealed an obliteration of the alveolar spaces by plugs of connective tissue distributed within the terminal bronchioles, alveolar ducts and spaces. No relevant cause was determined, and she was diagnosed with idiopathic organising pneumonia. The patient was discharged with oral glucocorticosteroid and supplemental oxygen therapy. One month later, the patient’s pulmonary status had progressively worsened, and she was re-admitted. She required higher oxygen concentrations and mechanical ventilation. Pharmacol…

Surgical treatment of solitary sternal metastasis from breast cancer Case report

2016

Bone metastasis is a frequent and early complication of breast cancer. This case report describes a technique for a partial exeresis of the sternum and the reconstruction of the pleura with autologous dermis from the lower abdomen and the loss of substance with a myocutaneous flap.We describe the case of a 50-year old woman with a sternal excavated lesion with pathologic fracture due to an invasive adenocarcinoma, treated with a partial exeresis of the sternum and the reconstruction with a myocutaneous flap.The patient doesn't show evidence of recurrent disease and the stability of her chest well preserved.Metastatic breast cancer to the sternum, if detected early and treated aggressively, …

Post-transplantation cyclophosphamide after HLA identical compared to haploidentical donor transplant in acute myeloid leukemia: a study on behalf of…

2022

Post-transplantation cyclophosphamide (PTCY) effectively prevents graft-versus-host disease (GVHD) after unmanipulated HLA-haploidentical hematopoietic stem cell transplantation (HSCT) and achieves low rates of GVHD in HLA-identical transplantation. To compare the outcomes of haploidentical versus HLA identical HSCT in patients undergoing HSCT for acute myeloid leukemia (AML) using PTCY. We conducted a retrospective study of 229 patients undergoing first HSCT for AML using PTCY with additional immunosuppression, 99 from matched sibling or unrelated donor (MSD/MUD) performed in 3 hospitals and 130 from haploidentical donors (haplo group) performed in 20 hospitals within the Spanish Group of …

P0623ACUTE RENAL FAILURE IN HAPOLIDENTICAL HEMATOPOIETIC CELL TRANSPLANTATION. TWO GRAFT VS HOST DISEASE (GVHD) PROFILAXIS PROTOCOL COMPARISON

2020

Abstract Background and Aims Haplo-hematopoietic cell transplantation (Haplo-HCT) assures a valid donor in short notice in over 95% of the patients with high risk haematological neoplasia. High doses of post-transplant cyclophosphamide, in combination with other inmunosupressive drugs like calcineurin inhibitors, rapamycine and micophenolate mofetil, is safe and useful in GVHD prevention. The aim of the study was to analyze and compare acute kidney injury (AKI) in the first 100 days after transplantation, the characteristics of the patients who went on haplo-HCT, and prophylaxis for GVHD with cyclosporine (n=32) (group 1) or rapamycine (group 2), in combination with other immunossupresors. …

Combined Immuno-Chemotherapy (R-CHOP) Results in Significantly Superior Response Rates and Time to Treatment Failure in First Line Treatment of Patie…

2004

Abstract Lymphomplasmocytoid/ic immunocytoma (LP-IC), including Waldenstrom’s macro-globulinemia and lymphoplasmacytoid lymphoma according to the Kiel classification (the latter one subsummed as a variant of B-CLL in the WHO classification), is an indolent lymphoma, which is incurable by conventional chemotherapy in the advanced stage of disease. The anti-CD20 antibody Rituximab has shown remarkable activity in indolent lymphomas, in particular when combined with chemotherapy. Based on these results the GLSG investigated the efficacy of a combined immuno-chemotherapy (R-CHOP: Rituximab 375 mg/m2 d0-1; cyclophosphamide 750 mg/m2 d1; doxorubicine 50 mg/m2 d1; vincristine 1.4 mg/m2 d1; prednis…

Efficacy of four cleaning solutions for the decontamination of selected cytotoxic drugs on the different surfaces of an automated compounding system

2018

The automated aseptic preparation of ready-to-administer antineoplastic drug solutions with robotic systems reduces the risk of occupational exposure. However, the surfaces in the preparation area of the robot are to be cleaned by wiping with an appropriate cleaning solution. The aim of the study was to evaluate the cleaning efficacy of four cleaning solutions on four surface materials installed in the APOTECAchemo robot. Predefined amounts of cisplatin (Cis), 5-fluorouracil (5-FU), and cyclophosphamide (CP) were intentionally spread on test plates made of stainless steel, aluminium, polyoxymethylene, and polycarbonate just as installed in the robotic system APOTECAchemo. After drying, the …

Genetically engineered V79 Chinese hamster cells metabolically activate the cytostatic drugs cyclophosphamide and ifosfamide.

1990

V79 cells, genetically engineered to express active cytochromes P450IIB1 and P450IA1, were used to study the cytotoxicity and mutagenicity of cyclophosphamide and ifosfamide. Cyclophosphamide, tested up to a concentration of 2 mM, was not cytotoxic in V79 nor in the P450IA1-expressing V79-derived cell line XEM2. Pronounced cytotoxicity was, however, observed in the P450IIB1-expressing V79-derived cell line SD1. Induction of gene mutations (acquisition of 6-thioguanine resistance) was observed in SD1 cells as well, but the effects were weak. Ifosfamide was inactive in V79 cells, but was cytotoxic in SD1 cells. Ifosfamide mustard, an active metabolite of ifosfamide, was equally cytotoxic and …

Molecular Remission Can Be Attained in Relapsed or Refractory Chronic Lymphocytic Leukemia (CLL) and Follicular Lymphomas after Reduced Intensity Con…

2004

Abstract RIC followed by allo-SCT is an effective salvage treatment for some relapsed hematologic malignancies due to the postulated graft versus tumour (GVT) effect. In order to evaluate the quality of the clinical response, we have investigated the molecular status of patients receiving allo-SCT for relapsed disease. Forty-four patients (19 chronic lymphocytic leukemias (CLL), 21 follicular lymphomas (FCL) and 4 small lymphocytic lymphomas (SLL)) were enrolled in a prospective phase II study. The median age was 54 years (range: 32–69 years). The median number of previous chemotherapy regimens was 2 (range: 1–5) and 23% of patients had already failed an auto-SCT. Before transplant 34% of p…

Immunochemotherapy with Fludarabine (F), Cyclophosphamide (C), and Rituximab (R) (FCR) Versus Fludarabine and Cyclophosphamide (FC) Improves Response…

2008

Abstract Introduction: Previous phase II studies have suggested that a combination of FCR may increase the outcome of both untreated and relapsed CLL pts. In order to validate this concept the German CLL study group (GCLLSG) initiated a multicentre, multinational phase III trial, CLL8, to evaluate the efficacy and tolerability of FCR versus FC for the first-line treatment of pts with advanced CLL. Methods and Patients: 817 pts with good physical fitness as defined by a cumulative illness rating scale (CIRS) score (Extermann et al., JCO 1998) of up to 6 and a creatinine clearance (cr cl) □d 70 ml/min were enrolled between July 2003 and March 2006. Pts were randomly assigned to receive 6 cour…
