RESUMO

BACKGROUND: Primary breast lymphoma (PBL) of low-grade histology is a rare disease. This multicentric retrospective study was carried out to determine clinical features, prognosis and relapse. PATIENTS AND METHODS: Patients with histologically proven, previously untreated follicular or marginal-zone PBL (MZL PBL) diagnosed from 1980 to 2003 were included in the study. Major end points were progression-free survival (PFS), overall survival (OS) and potential prognostic factors. RESULTS: We collected data on 60 cases of PBL [36 follicular and 24 marginal-zone lymphoma (MZL)]. Stage was I(E) or II(E) in 57 patients and IVE in three patients due to bilateral breast involvement. Surgery, chemotherapy and radiotherapy (RT), alone or in combination, were used as first-line treatments in 67%, 42% and 52% of patients, respectively. Overall response rate was 98%, with a 93% complete response rate. Five-year PFS were 56% for MZL and 49% for follicular PBL (P = 0.62). Relapses were mostly in distant sites (18 of 23 cases); no patients relapsed within RT fields. CONCLUSIONS: Our data showed an indolent behaviour of MZL PBL, comparable to other primary extranodal MZL. Conversely, patients with follicular PBL had inferior PFS and OS when compared with limited-stage nodal follicular non-Hodgkin's lymphomas, suggesting an adverse prognostic role of primary breast localisation in this histological subgroup.

RESUMO

PURPOSE: Primary lymphomas of the breast (PBNHL) are uncommon. Magnetic resonance imaging (MRI) features of these malignancies can be relevant in establishing the extent of disease and planning the appropriate therapeutic strategy, usually represented by chemo- and radiotherapy, rather than surgery. The purpose of this study was to assess MRI features of PBNHL. MATERIALS AND METHODS: MRI examinations performed on seven patients with known PBNHL were retrospectively evaluated. Lesions were analysed for both morphology and kinetics and classified according to the Breast Imaging Reporting and Data System (BI-RADS) categories. RESULTS: The mean MRI maximum diameter was 44 mm (range 12-69). Six lesions showed a mass-like enhancement; one lesion showed a non-mass-like enhancement. For mass-like lesions, kinetic curve assessment of initial rise showed slow enhancement in one lesion, rapid enhancement in four lesions and medium enhancement in one lesion. Assessment of delayed enhancement showed plateau in five lesions and washout in one lesion. MRI BI-RADS categories were distributed as follows: one BI-RADS II, one BI-RADS III, three BI-RADS IV and two BI-RADS V. CONCLUSIONS: MRI features of primary breast lymphomas in this study cohort suggest that the occurrence of a PBNHL should be considered in the presence of large enhancing lesions of the breast, especially if associated with skin thickening. MRI may also have an important role in the assessment of response to therapy and diagnosis of recurrence.

RESUMO

With the aim of developing an effective therapy for heavily pretreated refractory MM outpatients, we evaluated the OPPEBVCAD regimen, a Hodgkin's disease-derived protocol that includes many drugs effective in MM administered in a sequential schedule. Twenty-two pts aged 42-72 years, with symptomatic highly-pretreated refractory (18 cases), or primary resistant MM (four cases. including two pts with plasma cell leukemia-PCL) received this therapy every 28 days (2-4 cycles, followed by a maintenance program). Therapeutic response (Chronic Leukemia-Myeloma Task Force criteria) and performance status (PS) and pain (W.H.O.) were evaluated. All of the pts were evaluable for response. There were 9 (40%) objective responses (OR: stabilization of blood counts and bone lesions, serum calcium normalization, 50% or more reduction in the concentration of serum monoclonal component (MC), 90% reduction in Bence-Jones proteinuria), 8 (36%) partial responses (PR: 25-50% reduction in serum MC), 1 no response or stable disease (NR), and 4 (18%) cases of progressive disease (PD). OR plus PR were 77%. Of the 4 primary resistant tumors (2 PCL and 2 MM), 2 achieved PR, 1 OR (a PCL case) and 1 progressed. Median survival was 15 months for responding pts (OR plus PR) and 4.5 months for non-responders (NR plus PD). PS and pain improved in 15 pts and did not change in 9. The most frequent side effects were cytopenias, with one drug related infective death. The OPPEBVCAD regimen proved to be an effective therapy for refractory relapsing or primary resistant MM: in responders (two-thirds of the pts), survival was prolonged by about 10 months. Its efficacy in anthracycline-treated pts, as well as the feasibility of using it on an outpatient basis without any continuous drug infusions, make this regimen a promising third line salvage therapy.

RESUMO

The serum levels of some cytokines seem to correlate with outcome in Hodgkin's disease (HD) and may be helpful in formulating new and better prognostic systems. The aim of this study was to analyse the correlations between the serum levels of different cytokines and the clinico-hematological features suggestive of a worse prognosis. The study involved 31 pts with a "de novo" diagnosis of HD (median age: 30 yrs; M/F: 13/18; stage I/II vs III/IV: 19/12; B symptoms: 12; bulky disease and extranodal disease: 9). The serum levels of sCD30, TNFalpha, TNF receptor I and II, IL6, IL6 receptor, IL10, sICAM-1 were evaluated at diagnosis, and correlated with gender, age (< or =/> 30), stage (I-II vs III-IV), systemic symptoms, bulky disease, ESR ( or = 40), serum copper (< or =/> 170 microg/dL), WBC counts (< or =/> 15x10(9)/L), prognostic scores (PS) according to Hasenclever ( or = 2), and the presence of extranodal disease. Stages III/IV were associated with significantly higher levels of sCD30 and TNF-RI (p=0.03), systemic symptoms with significantly higher levels of sCD30, TNFalpha, IL6, TNF-RI (p=0.027, 0.03, 0.0005, 0.002), bulky disease with TNF-RI (p=0.03), high ESR with IL6 and TNF-RI (p=0.0011, 0.0001), high WBC counts with sCD30, IL6, TNF-RI (p=0.03, 0.002, 0.01), high serum copper with sCD30 and IL6 (p=0.05, 0.0004), higher PS with sCD30, IL6, TNF-RI (p=0.002, 0.0003, 0.005), extranodal disease with TNFalpha and IL6 (p=0.05, 0.01). It was possible to define cut-off levels for some cytokines (sCD30 > 33.15 U/mL, TNFalpha > 29.71 pg/mL, IL6 > 12.43 pg/mL, TNF-RI > 3.23 ng/mL, IL6-R > 57 ng/mL) that significantly correlate with systemic symptoms, higher disease stages, ESR, serum copper, WBC counts and PS. Our study shows that high sCD30, TNFalpha, IL6 and TNF-RI levels are associated with advanced disease or a worse prognostic score. In the context of multiparametric HD staging, cytokine evaluation may be useful for identifying candidates for more intensive therapies.

RESUMO

AIMS: Diffuse large B-cell lymphomas (DLBCL) can be divided into different subgroups (germinal center B-cell-like [GCB] and non-GCB) according to their gene expression profiles. Immunohistochemistry has been proposed as a surrogate for identifying these subgroups, but data about its efficacy in providing prognostic information are conflicting. METHODS AND RESULTS: This study retrospectively analyzed a series of 105 DLBCL, defined as GCB and non-GCB according to CD10, bcl-6, and MUM1 expression. All patients received a first-line anthracycline-based (CHOP-like) chemotherapy. A total of 50 patients (48%) were identified as GCB and 55 (52%) as non-GCB. The overall response rate was 89% (94/105), with 62 (59%) complete response. Disease progressions were equally distributed between the 2 subgroups and were not significantly different (P = .756) considering the primary site of involvement (nodal or extranodal). The median follow-up was 62 months (range 5-126 months). Overall survival at 5 years was not significantly different between the groups (P = .3468) and was 72.3% and 66.6% for GCB and non-GCB, respectively. CONCLUSION: The results do not support the prognostic value of GCB and non-GCB immunohistochemical categories in DLBCL of both nodal and extranodal origin. Furthermore, a limited number of antigens may be not sufficient to identify the same patterns defined by cDNA microarray. Prospective studies are warranted to address this issue.

RESUMO

VAD, (Vincristine, Doxorubicin and Dexamethasone) was initially proposed as a salvage therapy for myeloma patients in whom prior alkylating agent therapy failed, although in recent years VAD has been surpassed by novel combination therapies with new biological agents such as thalidomide (and its derivative, lenalidomide) and bortezomib. After the excellent results obtained by the novel agents, VAD can no longer be proposed in preparation to autologous transplantation, although there are still indications that VAD remains useful and clinically relevant in the initial treatment of symptomatic multiple myeloma.

RESUMO

BACKGROUND: The aim of this study was to assess clinicopathological characteristics and outcome in a series of primary ocular adnexal lymphomas (POALs). PATIENTS AND METHODS: Nineteen patients with localised (stage IE) POAL were followed for a median of 96 months (24-156). The diagnosis was based on surgical biopsies followed by immunohistochemistry in 16 cases or fine-needle aspiration followed by immunocytophenotypic analysis in three cases. Twelve patients were treated with local radiotherapy (RT), five with chemotherapy (CT), and two refused further therapy after apparently radical tumour removal achieved by the diagnostic excisional biopsy. RESULTS: The histological and immunological pattern was consistent with a diagnosis of MALT-type lymphoma (11 cases), follicular center non-Hodgkin's lymphoma (three cases). a large-cell variant of Burkitt's lymphoma (one case), and large-cell transformed MALT lymphoma (one case). Low-grade lymphoma was diagnosed in the three cases which underwent fine-needle aspiration biopsy. All of the patients achieved and maintained complete remission except for those treated with surgical excision alone (two MALT conjunctival lymphoma cases): one of these relapsed locally, the other experienced the systemic spread of a transformed diffuse large-cell lymphoma and died 72 months after diagnosis. The side effects consisted of two cases of RT-related cataract after 52 and 72 months. CONCLUSIONS: Regardless of histology, prognosis was excellent when surgery plus RT was adopted, and CT seems to be a valid alternative to RT. Surgery alone may be sub-optimal.

RESUMO

BACKGROUND: Thalidomide, as a single agent, has been recently found to induce a clinical response in one third of refractory or relapsed myeloma patients. Although it has been reported that thalidomide significantly inhibits angiogenesis. it is still unclear whether its clinical effect is mediated, at least in part, by its anti-angiogenic properties. PATIENTS AND METHODS: We evaluated thalidomide as a single agent in myeloma, myelodysplastic syndromes (MDS) and histiocytosis, i.e. hematological diseases characterized by increased angiogenesis, and measured prospectively a number of surrogate angiogenesis markers. RESULTS: Clinical responses were observed in 7 of 17 myeloma and 2 of 5 MDS patients. The histiocytosis patient had a partial response. At the time of the best clinical response, plasma levels of angiogenic growth factors, vascular endothelial growth factor (VEGF) and basic-fibroblast growth factor (b-FGF), were significantly decreased, and flow cytometry indicated a decrease of activated endothelial cells in the bone marrow of responding MDS patients. CONCLUSIONS: These observations confirm thalidomide efficacy in myeloma, suggest a possible use in MDS and histiocytosis and may contribute to the prediction of clinical response and to understanding the mechanism of thalidomide's action.
