Patients with mantle cell lymphoma (MCL) have an adverse outcome after relapse. Bendamustine has demonstrated a good efficacy and toxicity profile in previously reported trials. In this study, we present a retrospective analysis of the Spanish experience in relapsed/refractory MCL treated with bendamustine in combination or alone with the objective of knowing the efficacy and toxicity profile of this treatment in our current clinical practice. Fifty eight patients were registered: 67 % male with median age of 71 years, and 2 is the median number of previous lines. The most frequent bendamustine regimen was bendamustine plus rituximab (83 %). The median number of cycles was 5 (range 1-8). The overall response rate was 84 % with 53 % of complete response/unconfirmed complete response (CR/uCR). Median progression-free survival (PFS) was 16 months (95 % confidence interval (CI) 13.3-18.8), and for patients who achieved CR/uCR, it was 33 months (95 % CI 11.1-54.2). Median overall survival (OS) was 30 months (95 % CI 25.6-34.9). For PFS, only blastoid histology and not achieving CR after bendamustine had a significant negative impact on the univariate and multivariate analyses (p < 0.05). Nevertheless, for OS, only an elevated lactate dehydrogenase (LDH) had negative impact on both, univariate and multivariate analyses (p < 0.05). Only one case of treatment-related mortality in a 79-year-old patient with very bad performance status was reported. In 280 cycles, 12 (4 %) hospitalizations for febrile neutropenia were reported. In our population, bendamustine has been a good salvage treatment with a favorable toxicity profile in a non selected and heavily pretreated population of patients with MCL.
Background Subcutaneous (SC) versus intravenous (IV) administration is advantageous in terms of patient convenience and hospital efficiency. This study aimed to compare the effect of optimizing the processes involved in SC versus IV administration of rituximab and trastuzumab on hospital capacity and service quality. Methods This cross-sectional resource utilization study interviewed oncologists, hematologists, nurses, and pharmacists from 10 hospitals in Spain to estimate changes in processes associated with conversion from IV to SC rituximab and trastuzumab, based on clinical experience and healthcare use from administrative databases. Results Efficient use of SC formulations increased the monthly capacity for parenteral administration by 3.35% (potentially increasable by 5.75% with maximum possible conversion according to the product label). The weekly capacity for hospital pharmacy treatment preparation increased by 7.13% due to conversion to SC formulation and by 9.33% due to transferring SC preparation to the cancer treatment unit (potentially increasable by 12.16 and 14.10%, respectively). Monthly hospital time decreased by 33% with trastuzumab and 47% with rituximab. In a hypothetical hospital, in which all processes for efficient use of SC rituximab and/or trastuzumab were implemented and all eligible patients received SC formulations, the estimated monthly capacity for preparation and administration increased by 23.1% and estimated hospital times were reduced by 60–66%. Conclusions Conversion of trastuzumab and rituximab to SC administration could improve the efficiency of hospitals and optimize internal resource management processes, potentially increasing care capacity and improving the quality of care by reducing time spent by patients at hospitals.
Background: Background: Acute Myeloid Leukemias arising after cytotoxic therapy (t-AML) or with myelodysplasia-related changes (AML-MRC) share adverse risk features and poor outcomes after standard 3+7 chemotherapy. In a randomized clinical trial, CPX-351 has shown superior overall survival (OS) compared to standard anthracyclinecytarabine schedule in these AML subtypes. Aims:Aims: to evaluate the effectiveness of CPX-351 treatment in a real-world setting. Methods:Methods: adult t-AML and AML-MRC patients who have been treated upfront with CPX-351 in 35 Spanish centers between 2018 and 2021. All patients were included in the PETHEMA registry (NCT02606825). Primary end-point was OS. Secondary end points were complete remission with or without hematological recovery (CR/CRi), proportion of minimal residual negativity (MRD), rate of allogeneic hematopoietic stem cell transplant (HSCT) and safety. Results: Results:CPX-351 was administered to 74 patients as first induction chemotherapy. Median age was 67 (63-71) years, with 40% (30/74) of female patients. ECOG performance status score was 0-1 in 85% (53/62) patients. A diagnosis of t-
3045 Background: Lenalidomide is an oral IMiD® immunomodulatory compound with a dual mechanism of action, namely tumoricidal and immunomodulatory activity, and established clinical efficacy and safety in patients with multiple myeloma (MM). Lenalidomide plus dexamethasone (Len + Dex) was well tolerated and demonstrated significant improvements in response and favorable overall survival (OS) compared with Placebo + Dex in 2 pivotal phase 3 registration trials in patients with relapsed/refractory MM (RRMM; Weber et al, NEJM 2007; Dimopoulos et al, NEJM 2007). Previously, in a phase 3, multicenter, single-arm, open-label, expanded-access study (MM-018), Len + Dex demonstrated a predictable safety profile that can preserve patient quality of life (QoL) (Yong et al Haematologica 2010 [abstract #0944]). Here we report efficacy, safety, and QoL data for patients enrolled in the Spanish cohort of MM-018. Methods: Patients with progressive disease after > 2 cycles of antimyeloma treatment, or after relapse from treatment, with ECOG performance status ≤ 2 received 28-day cycles of Len (25 mg/day, D 1–21) plus Dex (40 mg/day, D 1–4, 9–12, and 17–20 for cycles 1–4; D 1–4 in subsequent cycles). Endpoints included overall response (≥ partial response [PR] by European Group for Blood and Marrow Transplantation criteria) and QoL assessments measured by EORTC QLQ C-30 and EORTC QLQ MY-20 questionnaires at baseline and week 24. All prophylaxis was administered at the investigator's discretion. Results: Sixty-three patients receiving ≥ 1 dose of Len + Dex were evaluated for efficacy, safety, and QoL. Median age was 62 years (21 [33.3%] were > 65 years). Prior therapies included thalidomide (n = 15, 24%) and bortezomib (n = 37, 59%). Additionally, 5 (8%) patients had a history of deep vein thrombosis (DVT), and 23 (37%) had a history of peripheral neuropathy. A PR or better was observed in 49 (78%) patients, including complete response (CR) in 13 (21%), very good partial response (VGPR) in 13 (21%), and PR in 23 (37%) patients. Median time to first response and best response was 2.7 and 4.5 months, respectively. Median duration of response was 18.4 months. Response depth improved after long-term treatment with Len + Dex, and 32/63 (51%) patients received >12 cycles of therapy. Beyond 12 cycles of therapy, 8 patients achieved VGPR and 12 patients achieved CR; compared with 5 patients and 1 patient, respectively, prior to 12 cycles. Median time to progression and progression-free survival were both 13.3 months; median OS has not yet been reached. Forty-two (67%) patients remained on study at 6 months. Compliance to QoL assessment questionnaires was ≥ 80%. Patient-reported improvements in QoL and disease symptoms measured by both questionnaires were observed in nearly all scales. EORTC QLQ C-30 scores revealed clinically meaningful improvement (> 5 points) for global QoL (n = 15, 40%), fatigue (n = 16, 42%), emotional function (n = 15, 40%), physical function (n = 12, 32%), role function (n = 11, 29%), social function (n = 11, 29%), cognitive function (n = 10, 26%), and pain (n = 9, 24%) at 6 cycles compared with baseline. Preservation of QoL in role function, emotional function, social function, and pain scores was observed at 6 cycles when compared with baseline in responders (≥ PR). EORTC QLQ MY-20 results revealed no relevant median change (> 5 points) from baseline in all scales for all patients completing questionnaires at baseline and 6 cycles, except for a meaningful improvement in future perspective scores (median 11.1-point change). Adverse events observed in this study were consistent with those previously reported with Len + Dex. Grade 3/4 hematologic events were experienced by 40 (64%) patients, and included neutropenia (n = 32, 51%), thrombocytopenia (n = 11, 17%), anemia (n = 10, 18%), and febrile neutropenia (n = 4, 6%). DVT (all grades) was experienced by 5 (8%) patients, and only one grade 3/4 new-onset peripheral neuropathy was observed after 6 cycles of treatment. Conclusions: Len + Dex treatment in this expanded-access study demonstrated efficacy and predictable safety, consistent with that of previously published trials for patients with RRMM. More patients achieved VGPR and CR after long-term therapy compared with those receiving < 12 cycles of therapy. Furthermore, QoL assessments at baseline and 6 months revealed that patients treated with Len + Dex showed meaningful improvements in certain QoL and symptom scores.
