The present results appear to be encouraging in terms of complete prophylaxis of CINV and treatment of breakthrough emesis in the setting of multiple-day chemotherapy.
Amyloid in bone marrow smears of patients affected by multiple myeloma Abstract Systemic AL amyloidosis is associated with nearly 15% of cases of multiple myeloma, but data on the frequency and significance of amyloid deposits in the bone marrow of patients affected by multiple myeloma without clinical signs of systemic amyloidosis are scanty. Bone marrow smears of 166 unselected patients affected by multiple myeloma (126 at diagnosis and 40 after treatment)were stained with Congo red and studied by transmission and birefringence microscopy. Both focal and diffuse storages were considered positive. Overall, 67 patients were positive and 99 were negative to Congo red and apple-green birefringence. In particular, 51 of the 126 patients studied at diagnosis and 16 of the 40 patients with advanced disease were positive. Seventeen patients were
The aim of this study was to determine the efficacy of palonosetron combined with dexamethasone in prevention of chemotherapy (CT)-induced nausea and vomiting (CINV) in patients receiving high-dose (HD)-CT with auto-SCT, and the efficacy of a second dose of palonosetron in treating breakthrough emesis. One hundred thirty-four patients treated with HD-CT and auto-SCT for hematologic malignancies received palonosetron as prophylaxis for CINV on the first day of conditioning; patients were also administered dexamethasone throughout the entire period of conditioning. If breakthrough emesis occurred, a second dose of palonosetron was administered at 72 h after the first administration. Complete response and complete protection were observed in 36 and 26% of patients, respectively. One-half of the patients, re-treated with palonosetron for breakthrough emesis, were successfully rescued. Treatment with palonosetron plus dexamethasone seems to be encouraging in terms of prophylaxis of CINV and treatment of breakthrough emesis in the setting of HD-CT.
Objective and Methods:In order to assess the efficacy of brentuximab vedotin (Bv) in combination with bendamustine (B) in multiple relapsed or refractory (RR) classic Hodgkin lymphoma (cHL), medical records of 47 patients treated with BvB in second relapse or beyond were reviewed. Results:The median number of previous treatments was 2 (1-4). Bv was given at 1.8 mg/kg on day 1 and bendamustine at 90 mg/m 2 on days 1 and 2 of a 21-day cycle. The median number of BvB cycles was 4 (2-7), and all patients were evaluable for efficacy. The CR and OR rates were 49% and 79%, respectively; 67% of responding patients and 2 in stable disease proceeded to a SCT procedure. After a median follow-up of 19 months (5-47), median PFS was 18 months (95%CI: 23-29), and the 2-year OS was 72%. Significantly longer PFS and OS were observed in patients attaining a major clinical response to treatment and in those who received consolidation with SCT. Fifteen (32%) patients experienced severe (G > 2) toxicity. The main toxicities were neutropenia (23%), gastrointestinal (10%), peripheral sensory neuropathy (11%), and infection (4%). Conclusion:Our real-world results suggest that BvB is an effective third-line rescue and bridge-to-transplant regimen for RR-cHL patients.
BACKGROUND: The combination schedule of rituximab, fludarabine and cyclophosphamide is considered the standard therapy for fit and young untreated chronic lymphocytic leukemia (CLL) patients. However, although this therapy improves progression free survival (PFS) and overall survival (OS), it has been associated with increased toxicity: 76% of the patients experienced at least one grade 3 or 4 event. Recently, encouraging clinical results in terms of safety and efficacy have been obtained using bendamustine in combination with rituximab (R-B) in untreated CLL patients. PURPOSE: We performed a multicentre retrospective study to assess safety and efficacy of R-B in a large group of untreated CLL patients. METHODS: One hundred and thirty six untreated CLL patients were recruited from 16 Italian Institutions and included in the present analysis. The median age was 69 years (range 43–85), with 49.3% of patients older than 70 years; 53.7% of cases were male. All patients had active disease as defined by the NCI-WG, and 27.2% were at Binet stage C. FISH data, available in 86/136 cases, identified a del(17p) in 5.1% of the patients and del(11q) in 5.9%. Sixty-four patients (47.1%) had a creatinine clearance ≤70 mL/min. Fifty-six % of cases showed a WHO performance status (PS) of I-II and 61% a CIRS comorbidity index >0. RESULTS: Among the 136 patients, 90 cases (66.2%) received B at the dosage of 90 mg/m2 on day 1 and 2 every 28 days, the remaining 46 cases received B at the dosage of 70 or 80 mg/m2. R was administered at the dosage of 375 mg/m2 on day 1 of all cycles in 59.6% of cases, while 40.4% received 375 mg/m2 on day 1 of the first cycle and 500 mg/m2 on day 1 of the other cycles. A total of 725 cycles were administered with a median number of 6 cycles per patient. Eighteen patients (13.2%) required early discontinuation of therapy before the sixth cycle for serious infections (n=7), persistent hematological toxicity (n=5), grade 4 dermatological toxicity (n=3), withdrawal of consent (n=2), hypersomnia and depression (n=1). Grade 3 or 4 adverse events for neutropenia, thrombocytopenia, and anemia were documented in 25.8%, 25.8%, and 16.2% of patients, respectively. Grade 3 or 4 severe infections occurred in 6.6% of patients. The overall response rate (ORR) was 93.4%, 48 patients (35.3%) achieved a complete response (CR), 79 (58.1%) a partial response (PR), 8 (5.9%) a stable disease (SD) and in 1 patient (0.7%) no response assessment was performed due to death prior to terminating therapy. In the high-risk group with del17p, 5/7 (71.4%) cases achieved a PR and 2 a SD. Age >70 years (P=0.026) and del17p (P=0.007) were the only two parameters significantly associated with a lower response rate, while del11q and unmutated IGHV, as well as creatinine clearance <70 ml/min, elevated β2-microglobulin, PS and CIRS CI >0 did not seem to impact on achievement of response. The only parameter predictive of the probability of achieving a CR was an age <70 years (P=0.03). When the analysis was restricted to cases with available FISH data, excluding patients with del17p, biological (CD38, ZAP-70, IGHV mutational status, FISH risk) and clinical parameters (age, β2-microglobulin, LDH, PS, CIRS CI, and creatinine clearance) did not significantly impact on the probability of achieving a response or on quality of response. After a median follow-up of 14 months, 2-year PFS was 87% and 2-year OS 84.5% (14 deaths occurred). Eight of 14 deaths were CLL-related (infections in 6 cases and disease progression in 2). CONCLUSIONS: The clinical practice of the Italian centers taking part in the study confirms that chemoimmunotherapy with R-B was an effective and well-tolerated treatment for untreated CLL patients. In patients with del17p the therapy appears to be less efficacious. Disclosures Off Label Use: Bendamustine in diffuse large B-cell lymphoma.
