Intervención nutricional en el paciente oncohematológico

Background: Oncohematological diseases such as lymphoma or leukaemia affect an increasing number of newly diagnosed patients in Spain and other countries. Both disease and treatment may have a negatively impact in the nutritional status of the patient. Malnutrition is not uncommon among oncohematological patients. This situation can compromised the course of the disease, the clinical response of the treatment and the patient’s quality of life. Method: The implementation of a multidisciplinary approach and a systematic and protocolled nutritional assessment would be useful when dealing with haematological malignancies. Results: We present a proposal of protocol for nutritional intervention in oncohematological patients. This proposal is been developed from the analysis of the published literature as well as clinical practice of a multidisciplinary team specialized in the management of patients with haematological malignanciesObjetivos: Las enfermedades oncohematológicas como el Linfoma o la Leucemia afectan a un número importante y creciente de personas en España. Tanto la enfermedad como las distintas modalidades de tratamiento que puede llegar a precisar el paciente a lo largo del curso de la misma impactan negativamente en el estado nutricional del paciente, no siendo infrecuente el desarrollo de desnutrición, situación que compromete la evolución, la respuesta al tratamiento y la calidad de vida del paciente. Método: La implementación de una estrategia multidisciplinar, sistematizada y protocolizada de valoración nutricional puede resultar de utilidad a la hora de abordar a los pacientes con enfermedades oncohematológicas. Resultados: Se presenta una propuesta de protocolo de evaluación y soporte nutricional en el paciente oncohematológico elaborada a partir del análisis de la literatura publicada al respecto, así como de la práctica clínica habitual de un equipo sanitario multidisciplinar especialmente implicado en el manejo de los pacientes con enfermedades oncohematológica

COVID-19 Severity and Survival over Time in Patients with Hematologic Malignancies: A Population-Based Registry Study

Mortality rates for COVID-19 have declined over time in the general population, but data in patients with hematologic malignancies are contradictory. We identified independent prognostic factors for COVID-19 severity and survival in unvaccinated patients with hematologic malignancies, compared mortality rates over time and versus non-cancer inpatients, and investigated post COVID-19 condition. Data were analyzed from 1166 consecutive, eligible patients with hematologic malignancies from the population-based HEMATO-MADRID registry, Spain, with COVID-19 prior to vaccination roll-out, stratified into early (February–June 2020; n = 769 (66%)) and later (July 2020–February 2021; n = 397 (34%)) cohorts. Propensity-score matched non-cancer patients were identified from the SEMI-COVID registry. A lower proportion of patients were hospitalized in the later waves (54.2%) compared to the earlier (88.6%), OR 0.15, 95%CI 0.11–0.20. The proportion of hospitalized patients admitted to the ICU was higher in the later cohort (103/215, 47.9%) compared with the early cohort (170/681, 25.0%, 2.77; 2.01–3.82). The reduced 30-day mortality between early and later cohorts of non-cancer inpatients (29.6% vs. 12.6%, OR 0.34; 0.22–0.53) was not paralleled in inpatients with hematologic malignancies (32.3% vs. 34.8%, OR 1.12; 0.81–1.5). Among evaluable patients, 27.3% had post COVID-19 condition. These findings will help inform evidence-based preventive and therapeutic strategies for patients with hematologic malignancies and COVID-19 diagnosis.Depto. de MedicinaFac. de MedicinaTRUEFundación Madrileña de Hematología y HemoterapiaFundación Leucemia y LinfomaAsociación Madrileña de Hematología y Hemoterapiapu

Lenalidomide in combination with R-ESHAP in patients with relapsed or refractory diffuse large B-cell lymphoma: a phase 1b study from GELTAMO group

Diffuse large B-cell lymphoma (DLBCL) patients failing rituximab-containing therapy have a poor outcome with the current salvage regimens. We conducted a phase 1b trial to determine the maximum tolerated dose (MTD) of lenalidomide in combination with R-ESHAP (rituximab, etoposide, cisplatin, cytarabine, methylprednisolone) (LR-ESHAP) in patients with relapsed or refractory DLBCL. Efficacy data were collected as a secondary objective. Subjects received 3 cycles of lenalidomide at escalating doses (5, 10 or 15 mg) given on days 1–14 of every 21-day cycle, in combination with R-ESHAP. Responding patients received BEAM (carmustine, etoposide, cytarabine, melphalan) followed by autologous stem-cell transplantation. Lenalidomide 10 mg/d was identified as the MTD because, in the 15 mg cohort, one patient experienced dose-limiting toxicity (grade 3 angioedema) and two patients had mobilization failure. A total of 19 patients (3, 12 and 4 in the 5, 10 and 15 mg cohorts, respectively) were evaluable. All toxicities occurring during LR-ESHAP cycles resolved appropriately and no grade 4–5 non-haematological toxicities were observed. The complete remission and overall response rates were 47·4% and 78·9%, respectively. With a median follow-up of 24·6 (17·4–38·2) months, the 2-year progression-free survival and overall survival were 44% and 63%, respectively. In conclusion, the LR-ESHAP regimen is feasible and yields encouraging outcomes

Managing the front‐line treatment for diffuse large B cell lymphoma and high‐grade B cell lymphoma during the COVID‐19 outbreak

The COVID-19 pandemic has dramatically challenged care for cancer patients, especially those with active treatment who represent a vulnerable population for SARS-CoV-2 infection. Aggressive lymphoid neoplasms, such as diffuse large B cell lymphoma and high-grade B cell lymphoma, need to be treated without delay in order to get the best disease outcome. Because of that, our clinical practice was changed to minimise the risk of SARS-CoV-2 infection while continuing haematological treatment. In this report, we analyse the management of front-line therapy in 18 patients during the COVID-19 outbreak, as well as the results of the implemented measures in their outcome

Immunochemotherapy With Obinutuzumab or Rituximab for Previously Untreated Follicular Lymphoma in the GALLIUM Study: Influence of Chemotherapy on Efficacy and Safety

Purpose; The GALLIUM study (ClinicalTrials.gov identifier: NCT01332968) showed that obinutuzumab (GA101; G) significantly prolonged progression-free survival (PFS) in previously untreated patients with follicular lymphoma relative to rituximab (R) when combined with cyclophosphamide (C), doxorubicin, vincristine (V), and prednisone (P; CHOP); CVP; or bendamustine. This report focuses on the impact of chemotherapy backbone on efficacy and safety. Patients and Methods: A total of 1,202 patients with previously untreated follicular lymphoma (grades 1 to 3a), advanced disease (stage III or IV, or stage II with tumor diameter $ 7 cm), Eastern Cooperative Oncology Group performance status 0 to 2, and requiring treatment were randomly assigned 1:1 to G 1,000 mg on days 1, 8, and 15 of cycle 1 and day 1 of subsequent cycles or R 375 mg/m2 on day 1 of each cycle, for six to eight cycles, depending on chemotherapy (allocated nonrandomly by center). Responding patients received G or R for 2 years or until disease progression. Results: Baseline Follicular Lymphoma International Prognostic Index risk, bulky disease, and comorbidities differed by chemotherapy. After 41.1 months median follow-up, PFS (primary end point) was superior for G plus chemotherapy (overall hazard ratio [HR], 0.68; 95% CI, 0.54 to 0.87; P= .0016), with consistent results across chemotherapy backbones (bendamustine: HR, 0.63; 95% CI, 0.46 to 0.88; CHOP: HR, 0.72; 95% CI, 0.48 to 1.10; CVP: HR, 0.79; 95% CI, 0.42 to 1.47). Grade 3 to 5 adverse events, notably cytopenias, were most frequent with CHOP. Grade 3 to 5 infections and second neoplasms were most frequent with bendamustine, which was associated with marked and prolonged reductions in T-cell counts. Fatal events were more frequent in patients treated with bendamustine, possibly reflecting differences in patient risk profiles. Conclusion: Improved PFS was observed for G plus chemotherapy for all three chemotherapy backbones. Safety profiles differed, although comparisons are confounded by nonrandom chemotherapy allocation

Classification, prevalence, and outcomes of anticancer therapy-induced cardiotoxicity: the CARDIOTOX registry

Aim: Cardiotoxicity (CTox) is a major side effect of cancer therapies, but uniform diagnostic criteria to guide clinical and research practices are lacking. Methods and results: We prospectively studied 865 patients, aged 54.7 ± 13.9; 16.3% men, scheduled for anticancer therapy related with moderate/high CTox risk. Four groups of progressive myocardial damage/dysfunction were considered according to current guidelines: normal, normal biomarkers (high-sensitivity troponin T and N-terminal natriuretic pro-peptide), and left ventricular (LV) function; mild, abnormal biomarkers, and/or LV dysfunction (LVD) maintaining an LV ejection fraction (LVEF) ≥50%; moderate, LVD with LVEF 40–49%; and severe, LVD with LVEF ≤40% or symptomatic heart failure. Cardiotoxicity was defined as new or worsening of myocardial damage/ventricular function from baseline during follow-up. Patients were followed for a median of 24 months. Cardiotoxicity was identified in 37.5% patients during follow-up [95% confidence interval (CI) 34.22–40.8%], 31.6% with mild, 2.8% moderate, and 3.1% with severe myocardial damage/dysfunction. The mortality rate in the severe CTox group was 22.9 deaths per 100 patients-year vs. 2.3 deaths per 100 patients-year in the rest of groups, hazard ratio of 10.2 (95% CI 5.5–19.2) (P < 0.001). Conclusions: The majority of patients present objective data of myocardial injury/dysfunction during or after cancer therapy. Nevertheless, severe CTox, with a strong prognostic relationship, was comparatively rare. This should be reflected in protocols for clinical and research practices

A phase II multicenter study of the anti-CD19 antibody drug conjugate coltuximab ravtansine (SAR3419) in patients with relapsed or refractory diffuse large B-cell lymphoma previously treated with rituximab-based immunotherapy

This phase II, single-arm, multicenter study examined the efficacy and safety of coltuximab ravtansine (an anti-CD19 antibody drug conjugate) in 61 patients with histologically documented ( de novo2clinicaltrials.gov identifier: 01472887) or transformed) relapsed or refractory diffuse large B-cell lymphoma who had previously received rituximab-containing immuno-chemotherapy. Patients had received a median of 2.0 (range 0-9) prior treatment regimens for diffuse large B-cell lymphoma and almost half (45.9%) had bulky disease (≥1 lesion >5 cm) at trial entry. Patients received coltuximab ravtansine (55 mg/m) in 4 weekly and 4 biweekly administrations until disease progression or unacceptable toxicity. Forty-one patients were eligible for inclusion in the per protocol population. Overall response rate (International Working Group criteria) in the per protocol population, the primary end point, was 18/41 [43.9%; 90% confidence interval (CI:) 30.6-57.9%]. Median duration of response, progression-free survival, and overall survival (all treated patients) were 4.7 (range 0.0-8.8) months, 4.4 (90%CI: 3.02-5.78) months, and 9.2 (90%CI: 6.57-12.09) months, respectively. Common non-hematologic adverse events included asthenia/fatigue (30%), nausea (23%), and diarrhea (20%). Grade 3-4 adverse events were reported in 23 patients (38%), the most frequent being hepatotoxicity (3%) and abdominal pain (3%). Eye disorders occurred in 15 patients (25%); all were grade 1-2 and none required a dose modification. Coltuximab ravtansine monotherapy was well tolerated and resulted in moderate clinical responses in pre-treated patients with relapsed/refractory diffuse large B-cell lymphoma

Brentuximab vedotin and ESHAP is highly effective as second-line therapy for Hodgkin lymphoma patients (long-term results of a trial by the Spanish GELTAMO Group)

Background: In this work, we assessed the efficacy and safety of brentuximab vedotin (BV) plus ESHAP (BRESHAP) as second-line therapy for Relapsed/Refractory Hodgkin lymphoma (RRHL) to improve the results before autologous stem-cell transplantation (ASCT). Patients and methods: This was a multicenter, open-label, phase I–II trial of patients with RRHL after first-line chemotherapy. Treatment had three 21-day cycles of etoposide, solumedrol, high-dose AraC, and cisplatin. BV was administered at three dose levels (0.9, 1.2, and 1.8 mg/kg) intravenous on day ‒1 to 3 + 3 cohorts of patients. Final BV dose was 1.8 mg/kg. Responding patients proceeded to ASCT, followed by three BV courses (1.8 mg/kg, every 21 days). Main end points for evaluation were maximum tolerable dose and overall and complete response (CR) before ASCT. Results: A total of 66 patients were recruited (median age 36 years; range 18–66): 40 were primary refractory, 16 early relapse and 10 late relapse. There were 39 severe adverse events were reported in 22 patients, most frequently fever (n = 25, 35% neutropenic), including 3 deaths. Grade 3–4 hematological toxicity presented in 28 cases: neutropenia (n = 21), thrombocytopenia (n = 14), and anemia (n = 7). Grade ≥3–4 extrahematological adverse events (≥5%) were non-neutropenic fever (n = 13) and hypomagnesaemia (n = 3). Sixty-four patients underwent stem-cell mobilization; all collected >2×10e6/kg CD34+ cells (median 5.75; range 2.12–33.4). Overall response before transplant was 91% (CI 84% to 98%), including 70% (CRs 95% CI 59% to 81%). 60 patients were transplanted with no failure engraftments. Post-transplant response was CR in 49 patients (82% CI 73% to 91%) and partial responses in six (10% CI 5% to 15%). After a mean follow-up of 27 months, the 30-month time to treatment to failure was 74% (95% CI 68% to 80%), progression-free survival 71% (95% CI 65% to 77%), and overall survival 91% (CI 84% to 98%). Conclusion: BRESHAP looks a safe and effective pre-transplant induction regimen, does not jeopardize transplant and allows long-term remissions and survival
