An unusual cause of adrenal insufficiency with elevation of 17-hydroxyprogesterone: case report.

Background: We present an intriguing case of primary adrenal lymphoma, with associated primary adrenal insufficiency (PAI), in a patient presenting a transitory partial 21-hydroxylase deficiency during the active phase of the adrenal disease.

Case Presentation: An 85-years old woman was referred because of worsening asthenia, lumbar pain, generalized myalgia and arthralgia. During investigations a computed tomography (CT) scan evidenced two large bilateral adrenal masses, highly suspicious for primary adrenal tumor.

Tandem autologous-reduced intensity allogeneic stem cell transplantation in high-risk relapsed Hodgkin lymphoma: a retrospective study of the Lymphoma Working Party-EBMT.

Autologous hematopoietic stem cell transplantation (ASCT) is curative for a proportion of patients with relapsed/refractory (R/R) Hodgkin lymphoma (HL). However, there is a small group of patients with high-risk of relapse after ASCT that might benefit from other approaches. We conducted a retrospective analysis on 126 patients treated with tandem ASCT-reduced intensity conditioning (RIC)-allogeneic-SCT and reported to the EBMT registry to analyze the efficacy and safety of this approach.

Safety and efficacy of (90) yttrium-ibritumomab-tiuxetan for untreated follicular lymphoma patients. An Italian cooperative study.

(90) Yttrium ((90) Y)-Ibritumomab-Tiuxetan combines the targeting advantage of a monoclonal antibody with the radiosensitivity of Follicular Lymphoma (FL). Previous studies showed that 90Y-IT is safe and effective in relapsed/refractory indolent FL, irrespective of prior treatment with rituximab. This multicentre trial aimed to evaluate the safety and the efficacy of "upfront" single-agent ((90) Y)-Ibritumomab-Tiuxetan in advanced-stage FL.

Upfront high-dose sequential therapy (HDS) versus VACOP-B with or without HDS in aggressive non-Hodgkin's lymphoma: long-term results by the NHLCSG.

Background: There is not univocal concordance for using high-dose sequential therapy (HDS) as first-line treatment for aggressive non-Hodgkin's lymphoma (NHL). We designed this study to evaluate the usefulness of HDS followed by high-dose therapy (HDT) with autologous stem cell transplantation as front-line treatment in different subsets of aggressive NHL.

Patients And Methods: Among 223 patients aged 15-60 years with aggressive, advanced stage NHL, 106 patients were randomized to VACOP-B (etoposide, doxorubicin, cyclophosphamide, vincristine, prednisone, bleomycin) for 12 weeks (plus HDS/HDT in case of persistent disease) (arm A), and 117 patients to VACOP-B for 8 weeks plus upfront HDS/HDT (arm B).

Reduced intensity conditioning for allograft after cytoreductive autograft in metastatic breast cancer.

The benefits of allografting noted in some malignant diseases might be safely extended to metastatic breast cancer by a combination of cytoreduction with high-dose chemotherapy (HDT) and autologous stem-cell transplant (ASCT) with graft-versus-tumour effect mediated by transplanted donor immune cells with nonmyeloablative allografting (reduced intensity conditioning transplantation, RICT). 17 patients with heavily pretreated disease were given tandem transplants. 13 patients sustained donor engraftment.

Fludarabine, cyclophosphamide and mitoxantrone for untreated follicular lymphoma: a report from the non-Hodgkin's lymphoma co-operative study group.

The aim of the study was to determine the safety and efficacy of the combination of fludarabine (FLU), cyclophosphamide (CY) and mitoxantrone (FLU/CY/MITO) in untreated follicular lymphomas (FL), Sixty patients with newly diagnosed stage II bulky to IV FL, median age 59 years (range 36-70), received FLU/CY/MITO regimen (FLU 25 mg/m2 days 1-3, CY 300 mg/m2 days 1-3, Mito 10 mg/m2 day 1). Patients received antibiotic oral prophylaxis during all treatments, and growth factors (G-CSF) when grade III granulocytopenia (WHO) occurred. The overall response rate was 87%: 46 patients achieved complete response (CR) (77%), 6 a partial response (10%) and 8 were non-responders.

[Neoplastic residues in the trocar tract in oncologic laparoscopic surgery].

Aim: The laparoscopic approach to malignant diseases runs up against both old and new problems: respect for the principles of radicality, operating times, the postoperative course and surgical complications, long-term oncological results in terms of survival and recurrence of the disease. One of the problems which has received most attention regards the onset of a metastasis on a trocar scar or a mini-laparotomy recurrence. Trocar site tumor recurrences have been described in the literature following laparoscopic surgery in almost all abdominal malignant pathologies (colorectal, gynaecological, pancreatic, etc.

Molecular analysis of patients with relapsed or refractory intermediate-high grade non-Hodgkin's lymphoma with bone marrow infiltration undergoing peripheral blood progenitor cell transplantation.

Background And Objectives: IgH gene rearrangement studies with a polymerase chain reaction (PCR) technique can detect the persistence of clonal cells at molecular level during the remission phase. This persistence of clonal cells can be used to establish the relationship between minimal residual disease (MRD) and clinical outcome. We have developed a three-step single strand conformational polymorphism PCR strategy which is able to detect clonal B lymphoid cells at a frequency as low as 1 clonal cell in 10(6) normal cells.

Fludarabine in combination with cyclophosphamide or with cyclophosphamide plus mitoxantrone for relapsed or refractory low-grade non-Hodgkin's lymphoma.

Background And Objectives: We report the activity of two combinations of fludarabine (FLU), one with cyclophosphamide (FLU/CY) and the second with CY plus mitoxantrone (FLU/CY/MITO). The aim of the study was to evaluate the activity and toxicity of these two schedules in patients with non-Hodgkin's lymphoma (NHL).

Design And Methods: Twenty-two patients with recurrent low grade non-Hodgkin's lymphoma (LGL) received FLU/CY (FLU 25 mg/m(2) days 1 to 3, CY 300 mg/m(2) days 1 to 3), and 31 patients received FLU/CY/MITO (FLU 25 mg/m(2) days 1 to 3, CY 300 mg/m(2) days 1 to 3, mitoxantrone 10 mg/m(2) day 1).

Amifostine (WR-2721), a cytoprotective agent during high-dose cyclophosphamide treatment of non-Hodgkin's lymphomas: a phase II study.

Clinical trials indicate that amifostine may confer protection on various normal tissues without attenuating anti-tumor response. When administered prior to chemotherapy or radiotherapy, it may provide a broad spectrum of cytoprotection including against alkylating drugs. The mechanism of protection resides in the metabolism at normal tissue site by membrane-bound alkaline phosphatase.

VACOP-B, high-dose cyclophosphamide and high-dose therapy with peripheral blood progenitor cell rescue for aggressive non-Hodgkin's lymphoma with bone marrow involvement: a study by the non-Hodgkin's Lymphoma Co-operative Study Group.

Background And Objective: Sequential treatment with the addition of high-dose therapy (HDT) and peripheral blood progenitor cell (PBPC) rescue has been reported to be active as front-line therapy in aggressive non-Hodgkin's lymphoma (NHL) with bone marrow (BM) involvement. We designed an intensive sequential therapy as front-line therapy in this subset of patients and conducted a phase II study.

Design And Methods: Patients with aggressive non-Hodgkin's lymphoma and BM involvement at diagnosis received 8 weeks of VACOP-B chemotherapy as induction therapy.

Alpha-interferon as induction and maintenance therapy in hairy cell leukemia: a long-term follow-up analysis.

Although in recent years the use of purine analogues has increased the percentage of long-term complete response the effect on overall survival of patients with hairy cell leukemia (HCL) is not yet clear. This study aimed to evaluate the long-term outcome (mean follow up of 92 months) of 64 patients receiving IFN as first-line therapy. IFN was well tolerated and effective.

High-dose cyclophosphamide followed by autografting can improve the outcome of relapsed or resistant non-Hodgkin's lymphomas with involved or hypoplastic bone marrow.

We report our experience of high-dose cyclophosphamide (HDCY) followed by high-dose therapy (HDT) and peripheral blood progenitor cell (PBPC) autografting in patients with diffuse, intermediate and high-grade non-Hodgkin's lymphomas who have failed conventional treatment. From 1991 to 1996, 54 consecutive patients pre-treated with a median of two chemotherapy lines entered the study. Eighteen patients (33%) were still responders to conventional chemotherapy (sensitive relapse), and 20 patients (37%) were in partial response (PR) after chemotherapy (CT).

[Multiple granular cell tumor: case report and review of the literature].

We describe a case of multiple granular cell tumour (GCT) in 41 years old man. It manifested as subcutaneous synchronous multiple lesions. GCT is, usually, a benign lesion that is histologically diagnosed after biopsy or surgical excision.

First line Fludarabine treatment of symptomatic chronic lymphoproliferative diseases: clinical results and molecular analysis of minimal residual disease.

Fludarabine (25 mg/m2 for 5 d, every 4 wk, for 6 courses) was administered as first line therapy in 32 symptomatic chronic lymphoproliferative diseases. All CLL patients achieved at least partial response (5 CR, 2 nPR, 9 PR) but 44% of patients relapsed. In LG-NHLs response and relapse rate were similar.

VACOP-B versus VACOP-B plus autologous bone marrow transplantation for advanced diffuse non-Hodgkin's lymphoma: results of a prospective randomized trial by the non-Hodgkin's Lymphoma Cooperative Study Group.

Purpose: The aim of this multicenter randomized study was to compare conventional therapy with conventional plus high-dose therapy (HDT) and autologous bone marrow transplantation (ABMT) as front-line treatment for poor-prognosis non-Hodgkin's lymphoma (NHL).

Patients And Methods: Between October 1991 and June 1995, 124 patients, aged 15 to 60 years, with diffuse intermediate- to high-grade NHL (Working Formulation criteria), stages II bulky (> or = 10 cm), III, or IV were enrolled. Sixty-one patients were randomized to receive etoposide, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin (VACOP-B) for 12 weeks and cisplatin, cytarabine, and dexamethasone (DHAP) as a salvage regimen (arm A), and 63 to receive VACOP-B for 12 weeks plus HDT and ABMT (Arm B).

Mobilization/transplantation of peripheral blood progenitor cells for aggressive non-Hodgkin's lymphoma with marrow involvement.

Thirty-five aggressive non-Hodgkin's lymphomas (NHL) with marrow involvement received high-dose cyclophosphamide (7 g/m2) and G-CSF in order to collect peripheral blood progenitor cells (PBPC). Fourteen patients were in partial remission, 16 patients were in relapse ("sensitive", 12; "resistant", 4) and 5 patients were in refractory to conventional treatment. A good yield of PBPC was obtained in 30 patients, while a low number of CD34+ cells and of CFU-GM was seen in two cases.

Mobilization/transplantation of peripheral blood progenitor cells for aggressive non-Hodgkin's lymphoma with marrow involvement.

Thirty-five aggressive non-Hodgkin's lymphomas (NHL) with marrow involvement received high-dose cyclophosphamide (7 g/m2) and G-CSF in order to collect peripheral blood progenitor cells (PBPC). Fourteen patients were in partial remission, 16 patients were in relapse ('sensitive', 12; 'resistant', 4) and five patients were refractory to conventional treatment. A good yield of PBPC was obtained in 30 patients, while a low number of CD34+ cells and of CFU-GM was seen in two cases.

Twelve years experience with high-dose therapy and autologous stem cell transplantation for high-risk Hodgkin's disease patients in first remission after MOPP/ABVD chemotherapy.

High-dose therapy followed by autografting can cure patients with aggressive Hodgkin's disease (HD) refractory or with early relapse to first-line combination chemotherapy. On the other hand, the eradication of the disease is rarely achieved in heavily pretreated patients. It has been suggested that patients with HD with very high risk characteristics at diagnosis, often relapse despite appropriate therapy with 7-8 drugs combination.

Desmoplastic malignant melanoma (neurotropic variant).

A case of neurotropic variant desmoplastic malignant melanoma is reported. The report deals with a tumor consisting of dense stroma in which fusiform cells are immersed and whose reduced capacity to produce melanin makes correct diagnosis difficult in the absence of an associated nevus lesion. Immunohistochemical characteristics and possible differential diagnoses are discussed.

Concurrent thymic stroma sarcoma (thymoliposarcoma) and breast carcinoma. Report of a case.

A case of sarcoma of thymic stroma with features of liposarcoma associated with breast carcinoma is presented. No previous reference was found in the literature to this association. It is possible that this event could be not entirely fortuitous but an element sustaining the pathogenetic theory relating stromal and epithelial neoplasias in the thymus.

Mobilization of cytogenetically 'normal' blood progenitors cells by intensive conventional chemotherapy for chronic myeloid and acute lymphoblastic leukemia.

Various lines of evidence suggest that substantial numbers of very primitive normal hematopoietic cells persist in the marrow of most patients with CML, despite the presence of an expanded Philadelphia-Chromosome (Ph) positive population, and that normal clones might, in certain circumstances, have a proliferative advantage over leukemic populations. We have recently demonstrated in 5/8 CML patients with blastic phase (BP) that the blood progenitor cells/(BPC) harvested during early recovery from marrow aplasia were Ph-negative on cytogenetic analysis, suggesting that leukapheresis may provide a useful source of 'normal' progenitors for subsequent reinfusions. We report here an update on 40 patients with Ph + CML and 9 patients with ALL in first or subsequent relapses with associated cytogenetic translocations including t(8;14) t(4;8) t(4;11) and t(9;22).
