RESUMO

Introduction: Skin-reducing mastectomy has been applied to several surgical techniques in which subcutaneous mastectomy is associated with various types of skin reduction, with preservation of a lower dermal flap to reinforce the inferior lateral seat of an implant. The aim of the study is to present a case series of patients with pendulous/ptotic and/or large-sized breasts treated for breast cancer at the Breast Surgery Unit of Istituto Nazionale Tumori IRCCS Fondazione "G. Pascale", Naples, Italy, with the superomedial pedicle skin-reducing mastectomy technique, two-stage reconstruction, and transaxillary video-assisted technique, when a postoperative radiotherapy was indicated. We verified its effectiveness by discussing its results, especially in patients who are candidates for postmastectomy radiotherapy. Materials and methods: A single-center retrospective study was performed between January 2020 and March 2021 on a prospectively filled database of conservative mastectomies. Of the 64 patients who underwent nipple/skin-sparing mastectomies in the mentioned period, 17 (mean age 46 years, range 30-62 years) were treated with superomedial pedicle skin-reducing mastectomy, with two-stage breast reconstruction through transaxillary video-assisted replacement expander with definitive prosthesis and contralateral symmetrization, selected for postmastectomy radiotherapy. Results: We had only three minor complications. No flap necrosis, no infections, no breast seromas, and no reconstructive failures were observed. During follow-up of the patients treated with video-assisted reconstruction, there were no cases of infection, hematoma, implant rupture, or suture dehiscence in the reconstructed breast. Discussion: Skin-reducing mastectomy with superomedial pedicle is a safe and reliable procedure to treat breast cancer in selected patients, i.e., those with pendulous/ptotic and or large-sized breasts. Particularly, in patients who undergo postmastectomy radiotherapy, the two-stage reconstruction with video-assisted transaxillary endoscopic approach can find its main indication, using incisions positioned far from the mammary region, offering numerous advantages.

RESUMO

The World Health Organization classification of myelodysplastic syndromes (MDS) is based on morphological evaluation of marrow dysplasia. We performed a systematic review of cytological and histological data from 1150 patients with peripheral blood cytopenia. We analyzed the frequency and discriminant power of single morphological abnormalities. A score to define minimal morphological criteria associated to the presence of marrow dysplasia was developed. This score showed high sensitivity/specificity (>90%), acceptable reproducibility and was independently validated. The severity of granulocytic and megakaryocytic dysplasia significantly affected survival. A close association was found between ring sideroblasts and SF3B1 mutations, and between severe granulocytic dysplasia and mutation of ASXL1, RUNX1, TP53 and SRSF2 genes. In myeloid neoplasms with fibrosis, multilineage dysplasia, hypolobulated/multinucleated megakaryocytes and increased CD34+ progenitors in the absence of JAK2, MPL and CALR gene mutations were significantly associated with a myelodysplastic phenotype. In myeloid disorders with marrow hypoplasia, granulocytic and/or megakaryocytic dysplasia, increased CD34+ progenitors and chromosomal abnormalities are consistent with a diagnosis of MDS. The proposed morphological score may be useful to evaluate the presence of dysplasia in cases without a clearly objective myelodysplastic phenotype. The integration of cytological and histological parameters improves the identification of MDS cases among myeloid disorders with fibrosis and hypocellularity.

RESUMO

This report describes the case of a previously healthy young man who presented with fever, pharyngitis, cervical lymphadenopathy, lymphocytosis, and severe thrombocytopenia. Serological tests for Epstein-Barr virus were diagnostic of a primary Epstein-Barr virus infectious mononucleosis but severe thrombocytopenia aroused the suspicion of a lymphoproliferative disease. T-cell receptor gene analysis performed on peripheral and bone marrow blood revealed a T-cell receptor γ-chain rearrangement without the evidence of malignancy using standard histologic and immunophenotype studies. Signs and symptoms of the infectious disease, blood count, and T-cell receptor gene rearrangement resolved with observation without the evidence of emergence of a lymphoproliferative disease. In the contest of a suspected lymphoproliferative disease, molecular results should be integrated with all available data for an appropriate diagnosis.

RESUMO

BACKGROUND: An increased incidence of second cancers has been reported in lymphoproliferative disorders. PATIENTS AND METHODS: We assessed the frequency, characteristics and predictive factors of second cancers in 230 patients with Waldenström macroglobulinemia (WM) and compared the incidence of second cancers in WM with that of an age- and sex-matched control population. RESULTS: Twenty-two patients (10%) developed solid cancers and 10 (4%) second hematologic malignancies. In a competing risk model, the cumulative incidence of solid cancers was 12% at 10 years and 17% at 15 years while the incidence of hematologic malignancies was 6% and 8%, respectively. The overall risk of second cancer in WM was 1.69 times higher than expected (P = 0.002). WM patients were at increased risk for diffuse large B-cell lymphoma [standardized incidence ratio (SIR) 9.24, P < 0.0001], myelodisplastic syndrome/acute myeloid leukemia (SIR 8.4, P < 0.0001), brain cancer (SIR 8.05, P = 0.0004). The risk of a second hematologic malignancy was fourfold higher in patients previously treated, though not reaching statistical significance (P = 0.19). CONCLUSIONS: WM patients are at higher risk of second cancers as compared with the general population. The sample size does not allow firm conclusions about the effect of therapy on the development of second cancers.

RESUMO

Acute myeloid leukemia (AML) is a heterogeneous disease increasing in frequency owing to an aging population. Decisions on intensive induction treatments, intensification and allografting rely on the ability to divide an apparently homogeneous group according to risk. A wide range of clinical, cytogenetic and molecular variables may be used to inform this task; here we examine those variables useful in assessing prognosis for a patient with non-acute promyelocitic AML focusing on core binding factor leukemia. In clinical practice, when counseling an individual patient with AML, a range of well-known clinical variables (age, performance status and tumor burden) and genetic variables (cytogenetic and gene mutation) must be considered to better define the prognostic risk.

RESUMO

Advanced age is one of the variables more frequently considered to be associated with an adverse prognosis in Waldenström's macroglobulinemia (WM). In a series of 238 symptomatic and asymptomatic WM patients, we retrospectively identified an age cut-off distinguishing two groups of patients with different outcome in terms of overall survival (OS), disease-specific survival (DSS) and treatment-free survival (TFS). Although for the OS the best cut-off was identified at 65 years with shorter OS for elderly patients, no difference was detected in terms of DSS between the two groups. Furthermore, patients over 65 years showed a longer TFS compared with patients under 65 years. Clinical and laboratory disease characteristics did not significantly differ between the two groups of patients except for ß2M level. Therefore, the poorer survival of patients over 65 years at diagnosis should probably be attributed to the higher number of no disease-related deaths and is independent from WM.

RESUMO

Since 2002, date of publication of the previous Italian Society of Haematology (SIE) practice guidelines for management of myelodysplastic syndromes (MDS), novel disease-modifying treatments have been introduced and the SIE commissioned an update. After a comprehensive review of the medical literature published since January 2001, the Expert Panel formulated recommendations for the management of adult and paediatric MDS, graded according to the available evidence. The major updates are: first-line hypomethylating agents in patients with INT2-high-risk disease; controlled use of first-line lenalidomide in low-INT1 risk transfusion-dependent patients with 5q deletion; deferasirox in low-INT1 patients with a relevant transfusional load; first-line high-dose ESA in low-INT1 patients with Hb <10 g/dl and endogenous EPO <500 U/l; allogeneic HSCT first-line therapy for INT2- and high-risk patients <65 years without severe co morbidities.

RESUMO

INTRODUCTION: To establish the role of positron-emission tomography (PET)-computed tomography (CT) in post-transplant lymphoproliferative disorder (PTLD) patients, compared to conventional imaging (ultrasonography/CT/magnetic resonance imaging) in relation to its accuracy, sensitivity and specificity. METHODS: 30 patients (26 males and 4 females), with a median age of 49.5 (range 18-74) years, were retrospectively evaluated. In 29 cases, the diagnosis was confirmed by histopathology. Malignant lymphoma was detected in 20 cases, polymorphic lymphoproliferative disorder in six cases, multiple myeloma in two cases and Hodgkin's disease in one case. A total of 49 PET-CTs (13 studies for staging at diagnosis and 36 studies at follow-up as assessment post-therapy) were compared to conventional imaging. Imaging results in accordance with disease status were assessed at a median follow-up of 17.8 (range 1.5-42.2) months post-PET-CT. RESULTS: In 41 of 49 examinations performed for staging and on follow-up, PET-CT and conventional imaging findings were concordant. Compared to conventional imaging, PET-CT showed comparable sensitivity (75 percent vs. 83 percent), similar specificity (100 percent in both modalities) and comparable accuracy (77 percent vs. 85 percent) during staging at diagnosis. PET-CT was found to be superior to conventional imaging modalities at follow-up, with greater sensitivity (100 percent vs. 81 percent), specificity (80 percent vs. 100 percent) and accuracy (97 percent vs. 83 percent). CONCLUSION: PET-CT is an accurate diagnostic tool for staging and for the follow-up of PTLD patients. It represents a good alternative imaging method to avoid contrast-related nephrotoxicity in patients who often develop impaired renal function secondary to chronic immunosuppressive therapy. However, further studies are recommended before considering PET-CT as a routine diagnostic tool in PTLD.

RESUMO

BACKGROUND: To evaluate the clinical outcome of patients with relapsed or refractory follicular lymphoma treated with immunochemotherapy, in vivo purging and high-dose therapy with autotransplant. PATIENTS AND METHODS: Sixty-four patients were enrolled in the trial. Primary end point was progression-free survival (PFS). Secondary end points were the in vivo purging effect on stem-cell harvest and the impact of molecular response on the outcome. RESULTS: At enrollment, 59% of patients were PCR+ for bcl-2 rearrangement in bone marrow (PCR-informative). After the immunochemotherapy, before mobilization, 97% obtained complete response or partial response and 87% of patients informative for bcl-2 were molecularly negative. Sixty-one patients proceeded to in vivo purging and peripheral blood stem cell (PBSC) mobilization with rituximab and high-dose AraC. The median number of CD34+ cells collected was 16.6 x 10(6)/kg. Of 33 PCR-informative patients, the harvests resulted in PCR- in all. Fifty-eight patients received high-dose therapy and autotransplant of in vivo purged PBSC. After a median follow-up of 3.5 years, 41 patients are in complete remission. Five-year PFS is 59%. CONCLUSION: This study demonstrates that patients with advanced relapsed or refractory follicular lymphoma treated with immunochemotherapy, in vivo purging and autotransplant may obtain long-lasting PFS. In bcl-2-positive patients, in vivo purging allows the harvest of lymphoma-free PBSC. Absence of the bcl-2 rearrangement after autotransplant is associated with persistent clinical remission.

RESUMO

Giving the impact of complete response (CR) on outcome of multiple myeloma patients addressed to high-dose melphalan, we explored the role of a pre-transplant intensification with 3 months thalidome plus dexamethasone therapy (Thal-Dex), after pulse-VAD induction. Seventy-four multiple myeloma patients (MM pts) uniformly treated, were retrospectively studied. The response rate after pulse-VAD were: CR 6%, VGPR 40%, PR 23%, MR 23%, and progression 8%. The response rate after Thal-Dex were similar: CR 11%, VGPR 39%, PR 17%, MR 9%, and progression 24%. Giving no advantage in terms of response rate with an additive toxicity, Thal-Dex does not seem useful for intensification before transplant.

RESUMO

In the perioperative management of patients on long-term oral anticoagulant (OAC) therapy the problem is balancing the thromboembolic (TER) and the haemorrhagic risk (HR) in the perioperative period. The Federazione Centri per la diagnosi della trombosi e la Sorveglianza delle terapie Antitrombotiche (FCSA) activated an online registry from November 2001 to August 2003 in order to collect information on the management of these patients in Italy. Four hundred and eleven patients, undergoing elective major (18%) and minor surgery (82%), from 7 centres, were registered. Three hundred and ninety-nine out of 411 patients received LMWH either once a day (310 patients) or twice a day (89 patients) during OAC therapy discontinuation. Two thromboembolic (0.48%) and 16 bleeding events (7 major; 1.7%) were reported. Notwithstanding the lower doses of heparin (54.3 U/kg o.d. and 64.4 U/kg b.i.d.), the thromboembolic complications are in line with those reported in the literature. The data of this study suggest that the intervention with LMWH may be relevant only in the high-risk patients as already proposed by others.

RESUMO

Alemtuzumab is a humanized (IgG(1)) rat monoclonal antibody to CD52 antigen and is currently used in the treatment of chronic lymphocytic leukemia (CLL) and other CD52-positive lymphoproliferative disorders. Various techniques have been developed to measure Alemtuzumab levels in human serum/plasma. The authors report on the validation of a very sensitive enzyme-linked immunosorbent assay (ELISA) to measure serum concentrations of the humanized IgG(1) using a rabbit polyclonal antibody specifically produced against the rat sequence of Alemtuzumab after papain digestion. The assay was successfully applied to test the serum samples of patients with B-lymphocyte CLL who received Alemtuzumab subcutaneously. This ELISA assay could be easily used to determine human serum levels of Alemtuzumab pre- and post-treatment to optimize dosing and scheduling and to study the relationship between dose and clinical response.

RESUMO

Antifungal therapy may be unable to eradicate invasive mycosis in leukemia patients. The presence of persisting pulmonary nodules owing to mycosis seems to increase the risk of fungal relapse after chemotherapy and transplant procedures. Between 1997 and 2004, 10 acute leukemia patients underwent pulmonary surgery for invasive mycosis. The median time from diagnosis of mycosis to surgery was 135 days (range 21-147). Three patients underwent emergency surgery, owing to hemoptysis. In the other seven patients with nodule/cavitation remaining after antifungal treatment, surgery (three wedge resections, four lobectomies) was scheduled before transplant. Pathologic examination confirmed two aspergillosis and three zygomycosis. The only side effect was pneumothorax in one case. Nine patients were considered cured. Six patients underwent bone marrow transplantation (three allogeneic, three autologous) with antifungal prophylaxis without relapse during the transplant procedure. In selected patients scheduled for bone marrow transplantation, surgical resection of localized pulmonary fungus nodules combined with antifungal prophylaxis seem to be an effective treatment for preventing mycotic relapse.

RESUMO

BACKGROUND: Hepatitis C virus (HCV) infection is frequently associated with B-cell non-Hodgkin's lymphomas. We investigated the prevalence of HCV infection in nongastric marginal zone lymphomas of mucosa-associated lymphoid tissue (MALT) in order to define the relationship between the viral infection and the presenting features, treatment, and outcome. METHODS: We retrospectively studied 172 patients with a histological diagnosis of marginal zone B-cell lymphoma of MALT, except for stomach, and with available HCV serology, among a series of 208 patients. RESULTS: HCV infection was documented in 60 patients (35%). Most HCV-positive patients (97%) showed a single MALT organ involvement. HCV-positive patients showed a more frequent involvement of skin (35%), salivary glands (25%), and orbit (15%). The majority of stage IV HCV-positive patients (71%) had a single MALT site with bone marrow involvement. The overall response rate was similar in HCV-positive (93%) and HCV-negative patients (87%). Overall survival (OS) and event-free survival (EFS) did not differ according to HCV infection. In multivariate analysis, advanced disease (stage III-IV) was associated with a poorer OS (P = 0.0001), irrespective of HCV serostatus. CONCLUSIONS: This study shows that nongastric marginal zone lymphomas are characterized by a high prevalence of HCV infection. Patients with involvement of a single MALT site have the highest prevalence of HCV. HCV-positive nongastric lymphomas of MALT show an indolent course similar to HCV-negative patients and seem an ideal target for exploiting the antilymphoma activity of antiviral treatments.

RESUMO

Systematic data on the ability of pegfilgrastim to mobilize stem cells after chemotherapy are scarce. We evaluated the efficacy of a single 6 mg dose of pegfilgrastim for mobilizing peripheral blood stem cells (PBSC) in aggressive lymphoma patients. Between July 2004 and October 2005, 17 aggressive non-Hodgkin's lymphoma and 11 poor-risk Hodgkin's lymphoma were treated with cycles containing cisplatin-aracytin. At the end of chemotherapy, the patients received 6 mg of pegfilgrastim. Duration of grade 4 neutropenia, adverse events, time to neutrophil recovery, peak and harvest of CD34+ cells were recorded. Twenty-seven out of 28 patients harvested a median of 17.3 x 10(6)/CD34+ cells (range 2.5-28.9) after a median of 9 days (range 8-12 days), with a single apheresis procedure in 25 cases. All patients had grade 3-4 neutropenia, median duration 3 days. The only adverse event was mild bone pain. To date, 13 patients have been autografted with a median of 15.4 x 10(6) CD34+ pegfilgrastim-mobilized cells per kg (range 2.5-28.9) with rapid and sustained engraftment. Mobilization, harvesting and autografting of pegfilgrastim-mobilized PBC can be successfully achieved in pretreated patients with aggressive lymphoma.

RESUMO

BACKGROUND: Paraprotein-associated neuropathies have heterogeneous clinical, neurophysiological, neuropathological and haematological features. Objectives. To prepare evidence-based and consensus guidelines on the clinical management of patients with both a demyelinating neuropathy and a paraprotein (paraproteinaemic demyelinating neuropathy, PDN). METHODS: Search of MEDLINE and the Cochrane library, review of evidence and consensus agreement of an expert panel. RECOMMENDATIONS: In the absence of adequate data, evidence based recommendations were not possible but the panel agreed the following good practice points: (1) Patients with PDN should be investigated for a malignant plasma cell dyscrasia. (2) The paraprotein is more likely to be causing the neuropathy if the paraprotein is immunoglobulin (Ig)M, antibodies are present in serum or on biopsy, or the clinical phenotype is chronic distal sensory neuropathy. (3) Patients with IgM PDN usually have predominantly distal and sensory impairment, with prolonged distal motor latencies, and often anti-myelin associated glycoprotein antibodies. (4) IgM PDN sometimes responds to immune therapies. Their potential benefit should be balanced against their possible side-effects and the usually slow disease progression. (5) IgG and IgA PDN may be indistinguishable from chronic inflammatory demyelinating polyradiculoneuropathy, clinically, electrophysiologically, and in response to treatment. (6) For POEMS syndrome, local irradiation or resection of an isolated plasmacytoma, or melphalan with or without corticosteroids, should be considered, with haemato-oncology advice.
