RESUMO

Hodgkin lymphoma (HL) is one of the most common types of cancer in the young and one of the most curable forms of cancer. Therefore, there has been an increasing interest in the study of long-term morbidities. The aims of the present study were to evaluate the prevalence and risk factors for impaired gonadal function in a retrospective cohort of 238 HL female survivors from Italy and Brazil and to analyse the role of oral contraceptives (OC) and GnRH-analogues. Besides data collection from HL databases, a specific questionnaire was administered to collect data on gonadal function. The median age at diagnosis was 25 years and the median follow-up was 7 years. Overall, 25% of the patients developed impaired gonadal function. Older age at diagnosis, front-line therapies containing alkylating agents and more than one treatment were independent risk factors, whereas the use of OC or GnRH-a reduced independently the risk of impaired gonadal function. The fertility rate among fertile survivors was low when compared with the general population. We confirmed that older age, type of front-line chemotherapy and a higher number of therapies are associated with gonadal function impairment in terms of infertility and premature menopause in female HL survivors. Also, the use of GnRH-a or OC was independently identified as a protective factor. Further prospective studies are needed to better understand the barriers to parenthood in HL survivors.

RESUMO

We report four patients (mean age 65 yr; range 40-77 yr) affected by acquired pure red cell aplasia (PRCA) complicating chronic lymphoid disorders and treated with anti-CD20 monoclonal antibody rituximab. Three out of four patients were given packed red cell transfusion. Steroids and recombinant erythropoietin (r-Epo) were also administered as first-line therapy without response. After a mean time of 57 d (range 23-62 d) from PRCA diagnosis, all patients received rituximab at a dosage of 375 mg/m(2)/wk for four consecutive weeks. First injection side effects of rituximab were minimal. All patients showed an increase in hemoglobin levels in response to rituximab, in one patient just after the first dose, in another patient after the second and in two other patients after the third dose. Three patients (75%) were considered in complete remission (CR) and one patient (25%) in partial remission 4 wk after the last rituximab infusion, despite a CR was obtained later (16 wk following the beginning of the therapy). Finally, at the last follow-up (mean 18.5 months, range 2-60 months), all patients were alive and in continue CR. Despite very limited in number, these results suggest that rituximab is very effective in the treatment of PRCA complicating B-cell chronic lymphoproliferative disorders.

RESUMO

Twenty-one patients with multiple myeloma, all relapsed after frontline autologous stem cell transplantation and all relapsed again after or resistant to thalidomide (employed as second line treatment) received bortezomib (1.3 mg/m(2) body surface twice weekly for 2 weeks followed by an interval of 10-12 days) without adjunct of steroids as third line therapy. Three patients died of progressive disease during the first 2 cycles with bortezomib. Eighteen patients received at least 2 cycles and were evaluated for response. According to EBMT criteria, two complete (negative immunofixation) and seven partial (reduction of M-component > 50-75%) remissions were achieved (ITT response rate 42.8%). Duration of response lasted from 2 to 14+ months. Grades 3-4 toxicities (thrombocytopenia, leucopenia, peripheral neuropathy and vasculitis) were observed in seven patients, but no patient interrupted the treatment due to side effects. We conclude that bortezomib alone may induce high quality responses as third line salvage therapy with acceptable toxicity in a significant proportion of homogeneously pre-treated myeloma patients with progressive disease after autologous transplantation and thalidomide.

RESUMO

Primary breast lymphomas (PBL) are uncommon neoplasms. Seven PBL were diagnosed between March 1993 and October 2002. A lumpectomy (n=4) or radical mastectomy (n=3) was performed; 5 patients were in clinical stage (CS) II and 2 in CS IV; 6 patients received the CEOP regimen (cyclophosphamide, vincristine, epirubicin and prednisone) after surgery and 4 also had additional radiotherapy; 1 patient did not receive any treatment after local excision. Five patients (71%) achieved complete remission and 2 (29%) partial remission, with an overall response rate of 100%. All remitter patients are alive and well after a median follow-up of 75 months (range 10--121 months). Two patients in partial remission died of progressive disease. After a median follow-up of 99 months (range 84--111 months) for surviving patients, the 10 year overall and disease-free survival rates are both 71%, with 5 patients well and still free of disease. We conclude that the optimal sequence of full-dose anthracycline-containing regimens and radiation therapy should be the treatment of choice for patients with PBL.

RESUMO

INTRODUCTION: The classification and the clinical management of adult acute lymphoblastic leukemias (ALL) that co-express myeloid antigens (MyALL) remain controversial because of the confusion of terms and criteria to define these cases. MATERIALS AND METHODS: The characteristics of 112 adult ALL patients were reviewed. The scoring systems proposed by Catovsky and EGIL Group to classify MyALL were applied to qualify cases with score 0 (group I), 0.5-1.5 (group II) and 2 (group III). RESULTS: Forty-seven (42%) cases co-expressed MyAgs (group II: 29; group III: 18). A greater percentage of MyALL cases belonged to the earlier B and T subclasses. Ph+ incidence, WBC count and expression of CD34, CD45RA and CD25 were higher in group III. All patients received intensive therapy: out of these, 93 (83%) achieved CR. Although the response did not correlate significantly with the co-expression of MyAgs, the patients with the highest score had the lowest CR rate: 72, 83 and 86% in groups III, II and I, respectively. Surprisingly, the DFS curve of group III proved to be the most favorable. However, the OS was not significantly different, even if a worse curve was observed in group II. Multivariate analysis showed that only score 2 significantly affected DFS. CONCLUSION: The scoring system accurately defines diagnosis and ontogeny of MyALL which appear to be related to incidence of Ph chromosome, elevated WBC count and elderly age. Consequently, fewer CR rates were documented in MyALL with the highest score. However, it was in this group that the good responders showed a greater capacity to continue in first remission.

RESUMO

Ninety patients with untreated, stage I-II A myeloma, were randomised to receive or not monthly infusions of pamidronate (PMD) for 1 year, without additional therapies. Follow-up ranged from 36 to 72 months (median 51 months). Three years after the start of the treatment, the disease had progressed in 25% of PMD treated patients and in 26.8% of controls (p n.s). Median time-to-progression was 16 and 17.4 months, respectively (p n.s). Among the 21 patients who required chemo-radiotherapy, skeletal events (osteolytic lesions, pathological fractures and/or hypercalcemia) developed in 9/11 (81.8%) controls and in 4/10 (40%) of treated patients (p < 0.01). "Prophylactic" administration of PMD may decrease the development of skeletal events, but does not reduce the rate and the time of disease progression in early-stage myeloma.

RESUMO

Four cases of hypereosinophilic syndrome (HES) treated with the tyrosine-kinase inhibitor imatinib-mesylate are reported. The drug was effective in three patients, but a prolonged clinical and hematological remission was obtained only in one patient, due to appearance of resistance or poor tolerability in the other cases. The dose of imatinib necessary to achieve a response ranged from 100 to 600 mg/d. One patient with evidence of a clonal T-cell population did not respond at all. We confirm the efficacy of imatinib in HES, but we also underline that type and duration of response may be variable. This could be due to different pathogenetic mechanisms of the disease in single patients.

RESUMO

PURPOSE: Although rituximab (R) is commonly used for patients with advanced follicular lymphoma (FL) requiring treatment, the optimal associated chemotherapy regimen has yet to be clarified. PATIENTS AND METHODS: We conducted an open-label, multicenter, randomized trial among adult patients with previously untreated stages II to IV FL to compare efficacy of eight doses of R associated with eight cycles of cyclophosphamide, vincristine, and prednisone (CVP) or six cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or six cycles of fludarabine and mitoxantrone (FM). The principal end point of the study was time to treatment failure (TTF). RESULTS: There were 534 patients enrolled onto the study. Overall response rates were 88%, 93%, and 91% for R-CVP, R-CHOP, and R-FM, respectively (P=.247). After a median follow-up of 34 months, 3-year TTFs were 46%, 62%, and 59% for the respective treatment groups (R-CHOP v R-CVP, P=.003; R-FM v R-CVP, P=.006; R-FM v R-CHOP, P=.763). Three-year progression-free survival (PFS) rates were 52%, 68%, and 63% (overall P=.011), respectively, and 3-year overall survival was 95% for the whole series. R-FM resulted in higher rates of grade 3 to 4 neutropenia (64%) compared with R-CVP (28%) and R-CHOP (50%; P< .001). Overall, 23 second malignancies were registered during follow-up: four in R-CVP, five in R-CHOP, and 14 in R-FM. CONCLUSION: In this study, R-CHOP and R-FM were superior to R-CVP in terms of 3-year TTF and PFS. In addition, R-CHOP had a better risk-benefit ratio compared with R-FM.

RESUMO

The incidence of non-Hodgkin lymphomas increases with age. Non-pegylated liposomal formulations of doxorubicin (Myocet®) reduce systemic and cardiac toxicity especially in the elderly, who often have cardiac diseases. We treated 80 patients (mean age 70.9 years) with poor-risk diffuse large B-cell lymphoma with the R-COMP 21 regimen (Myocet® 50 mg/m(2), cyclophosphamide 750 mg/m(2), vincristine 1.4 mg/m(2), rituximab 375 mg/m(2), prednisone 100 mg/day). In all, 82.5% and 13.7% patients showed complete and partial responses, respectively. Sixty-two of the 80 patients are alive and disease-free (77.5%), while 3/80 are alive with active disease and 15 patients (18.7%) have died (median follow-up: 31 months). The estimated probability of overall survival at 12/24 months from admission was 93.5/87.3%, respectively. There were no therapy-related cardiac events and the ejection fraction improved (from 51.6 ±â€Š6.9% to 54.2 ±â€Š3.9%). Grade 3-4 neutropenia occurred in 22% of patients. We concluded that Myocet® shows both efficacy and tolerability, mainly at the cardiac level.

RESUMO

We conducted a retrospective analysis on 168 adult patients with newly diagnosed, limited-stage (I and II) diffuse large B-cell lymphoma (DLBCL) treated from 1988 to 2004 with PROMECE-CYTABOM (P-C) plus involved-field radiation therapy (IF-RT). At the end of P-C, the overall response rate was 92%. Radiotherapy (RT) was delivered to 84% of cases. With a median follow-up of 95 months, overall survival (OS), relapse free survival (RFS), and failure free survival at 5 and 10 years was 84% and 77%, 81% and 75%, 71% and 67%, respectively. Age (>60 years, p = 0.002), serum albumin (<3.5 g/dL; p = 0.015), and RT (p < 0.001) were independent predictors of OS. For patients in complete remission the administration of RT didn't improve both RFS and OS. This study confirms that patients with localized aggressive lymphoma have a high chance of cure with anthracycline containing regimens. Though the regimen used to treat these patients does not contain rituximab, results are considered excellent both in terms of efficacy and safety.

RESUMO

BACKGROUND: The acknowledged effectiveness of vinblastine, bleomycin, and methotrexate (VBM) chemotherapy in patients with early-stage Hodgkin lymphoma has been associated with conflicting toxicity reports. METHODS: One hundred forty-three patients were evaluated clinically and had favorable Stage IA or IIA Hodgkin lymphoma. Ninety-three patients were treated with the standard VBM schedule combined with extended-field radiotherapy (EF-RT), leaving the choice of the therapeutic sequence free. Fifty subsequent patients were treated with a slightly modified VBM schedule (VbMp) combined with RT limited to involved fields (IF-RT) and delivered only after the end of chemotherapy. In the VbMp schedule, intervals between cycles were 21 days instead of 28 days, bleomycin doses were reduced, small doses of prednisone were given orally, and the interval before RT was prolonged. RESULTS: Clinical response was complete in 96% of patients who were treated with VBM plus EF-RT and in 94% of patients who were treated with VbMp plus IF-RT. Recurrence rates were nearly identical (12% and 11%, respectively) over necessarily different follow-up (91 months and 33 months, respectively). Hematologic toxicity was tolerable in both trials, and pulmonary side effects were moderate in the first trial and negligible in the second. On the whole, treatment was tolerated better when RT followed chemotherapy. CONCLUSIONS: The VBM regimen was confirmed to be effective in patients with early-stage Hodgkin lymphoma. Administration of all cycles before RT improved tolerance; pulmonary toxicity probably is mitigated further by reduced bleomycin doses, mild prednisone therapy, and a more prolonged resting interval before RT. A slightly higher recurrence rate was expectable in the VBM plus IF-RT trial despite the actual intensification of vinblastine and methotrexate.
