Complementary and alternative medicine (CAM) is common in patients with cancer and its use is steadily increasing over time. We performed a multicenter survey in which the use of CAM in 442 Italian patients with chronic lymphocytic leukemia (CLL), the commonest form of leukemia in Western countries, was assessed. Data were collected by means of a face-to-face standardized questionnaire with several items. Mean age was 69 years; 258 patients (58%) were male and 184 (42%) female. Seventy-three patients (16.5%) were found to be CAM users. The most common CAM therapies were green tea, aloe formulations and high dose vitamins. Predictors of CAM use were female gender, younger age, higher education level, internet availability and newspaper reading. The reasons for CAM popularity among these patients are complex. Given the number of patients combining therapy with CAM and its possible drug interactions, doctor interest as well as patient education about CAM should be improved.

Polymorphisms of the Glutathione-S Transferase (GST) family may influence the prognosis in lymphoma patients. We aimed to validate the impact of GSTT1 and GSTM1 deletions and of the GSTP1Ile105Val polymorphism on outcome and toxicity in 140 patients with advanced Hodgkin's lymphoma enrolled in the prospective multicenter HD2000-GISL trial, comparing ABVD, BEACOPP and CEC regimens. Carriers of the GSTP1Ile105Val polymorphism had a higher rate of grade 3-4 anemia following treatment. Overall, our study failed to validate GST genotyping as prognostic factor for progression-free survival (PFS). Only the small cohort of patients with an international prognostic score (IPS) >3 and undeleted GSTT1 and/or GSTM1, treated with ABVD had worse progression-free survival (PFS) (GSTT1 + vs GSTT1-: HR 5.02, 95% C.I., 1.16-21.8, p = 0.031, GSTM1 + /GSTT1 + vs GSTM1-and/or GSTT1-: HR 4.61, 95% C.I. 1.28- 16.6, p = 0.019, respectively). No differences were observed for patients treated with intensified regimens, as BEACOPP and CEC. In conclusion, the prognostic role of GST polymorphism, if at all, is limited to a small subgroup of patients treated with standard ABVD regimen.

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 ± 6.9% to 54.2 ± 3.9%). Grade 3-4 neutropenia occurred in 22% of patients. We concluded that Myocet® shows both efficacy and tolerability, mainly at the cardiac level.

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.

Purpose: To compare doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) versus bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) versus cyclophosphamide, lomustine, vindesine, melphalan, prednisone, epidoxirubicin, vincristine, procarbazine, vinblastine, and bleomycin (COPPEBVCAD; CEC) for advanced Hodgkin's lymphoma (HL)., Patients and Methods: Three hundred seven patients with advanced HL (stage IIB, III, and IV) were randomly assigned to receive six courses of ABVD, four escalated plus two standard courses of BEACOPP, or six courses of CEC, plus a limited radiation therapy program., Results: After a median follow-up of 41 months, BEACOPP resulted in a superior progression-free survival (PFS), with a significant reduction in risk of progression (hazard ratio [HR] = 0.50) compared with ABVD. No differences between BEACOPP and CEC, or CEC and ABVD were observed. The 5-year PFS was 68% (95% CI, 56% to 78%), 81% (95% CI, 70% to 89%), and 78% (95% CI, 68% to 86%), for ABVD, BEACOPP, and CEC, respectively (BEACOPP v ABVD, P = .038; CEC v ABVD and BEACOPP v CEC, P = not significant [NS]). The 5-year overall survival was 84% (95% CI, 69% to 92%), 92% (95% CI, 84% to 96%), and 91% (95% CI, 81% to 96%) for ABVD, BEACOPP, and CEC, respectively (P = NS). BEACOPP and CEC resulted in higher rates of grade 3-4 neutropenia than ABVD (P = .016); BEACOPP was associated with higher rates of severe infections than ABVD and CEC (P = .003)., Conclusion: As adopted in this study BEACOPP is associated with a significantly improved PFS compared with ABVD, with a predictable higher acute toxicity.

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.

Purpose: MOPPEBVCAD (mechlorethamine, vincristine, procarbazine, prednisone, epidoxirubicin, bleomycin, vinblastine, lomustine, doxorubicin, and vindesine) chemotherapy with limited radiotherapy was devised in 1987 to reduce late toxicity and second tumor incidence while trying to improve effectiveness through increases of dose intensity and dose density. Late results, toxicity, and second tumor incidence were reviewed in all the patients treated., Experimental Design: The drugs of three previous alternating regimens [CAD (lomustine, melphalan, and vindesine), MOPP (mechlorethamine, vincristine, procarbazine, and prednisone), and ABV (doxorubicin, bleomycin, and vinblastine)] were intensified and hybridized, the cumulative dose of mechlorethamine was lowered, and irradiation was delivered to no more than two sites either bulky or partially responding to chemotherapy., Results: A total of 307 previously untreated advanced-stage patients underwent MOPPEBVCAD chemotherapy. Radiotherapy was delivered to 118 of 307 patients (38%). Remission was complete in 290 patients (94%). With a median follow-up of 114 months, 10-year overall, disease-free, and failure-free survival rates were 79%, 84%, and 71%, respectively. Forty-two patients relapsed and 60 died. The causes of death were Hodgkin's lymphoma in 36 patients, second neoplasms in 12, cardiorespiratory diseases in 4, pulmonary diseases in 2, and unknown in 6. Sixteen second tumors (of which nine were myelodysplasia and/or acute leukemia) were diagnosed in all. Outside this series of 307 patients, MOPPEBVCAD obtained complete responses in 12 of 15 relapsed and 9 of 9 refractory patients who had previously been treated with other regimens., Conclusions: Clinical response and long-term results are very satisfactory, whereas the second tumor incidence was lower than would have been expected with MOPP analogues. Given its response/late toxicity balance, MOPPEBVCAD does not undermine the leading role of ABVD as first-line regimen but can be indicated as a very effective second-line conventional therapy.

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.

Thirty-seven anaemic subjects with low-to-intermediate risk myelodysplastic syndrome (MDS) received the highly glycosylated, long-acting erythropoiesis-stimulating molecule darbepoetin-alpha (DPO) at the single, weekly dose of 150 microg s.c. for at least 12 weeks. Fifteen patients (40.5%) achieved an erythroid response (13 major and two minor improvements, respectively, according to International Working Group criteria). Such results are currently maintained after 7-22 months in 13 of the responders, one of whom required iron substitutive therapy during the treatment. One patient relapsed after 4 months. Another responder died after 5 months because of causes unrelated to the treatment. No relevant side-effects were recorded. At multivariate analysis, significant predictive factors of response were baseline serum levels of endogenous erythropoietin <100 IU/l, absent or limited transfusional needs, no excess of blasts and hypoplastic bone marrow. This study suggests that DPO, at the dose and schedule used, can be safely given in low-intermediate risk MDS and may be effective in a significant proportion of these patients.

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.

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.

Thirteen patients with low-to-intermediate risk myelodysplastic syndrome (MDS) received recombinant erythropoietin (r-EPO) at the single, weekly dose of 40.000 U for at least 8 weeks. Five patients (38.4%) achieved a major erythroid response (increased haemoglobin levels > 2 g/dl and/or transfusion independence), which is currently maintained after 3-11 months, without modification of r-EPO dose. This study suggests that 40.000 U r-EPO given once a week may be at least as effective as the more frequent (daily or three times a week) administrations of the drug usually employed in MDS patients.
