Honoring the moment of death: Lived experiences, practices, and rituals of internal medicine residents.

Given the limited information on physicians' practices at the time of pronouncing a patient's death, this study aimed to learn about the prevalence and purpose of internal medicine residents' practices, the obstacles to performing them and how they can be overcome. Responses to a questionnaire were analyzed using logistic regression, to compare respondents who did and did not have a ritual. Twenty-one interview transcripts were thematically analyzed. A total of 151 physicians responded to the questionnaire; 35 (22.3%) reported performing a private ritual at the time of patient death. Religious participants were 2.97 times more likely {CI: 1.18-7.41} to perform a ritual following a patient's death. Three main themes were found, indicating residents' need to pause and perform a practice to honor the patient, express their humanity, and cope with the overflow of emotions. Senior staff should support opportunities for residents to honor the moment of death.

Development and manufacture of novel locally produced anti-BCMA CAR T cells for the treatment of relapsed/refractory multiple myeloma: results from a phase I clinical trial.

Anti-B-cell maturation antigen (BCMA) chimeric antigen receptor T-cell (CAR T) therapy shows remarkable efficacy in patients with relapsed and/or refractory (R/R) multiple myeloma (MM). HBI0101, a novel second generation optimized anti- BCMA CAR T-cell therapy, was developed in an academic setting. We conducted a phase I dose-escalation study of HBI0101 (cohort 1: 150x106 CAR T cells, n=6; cohort 2: 450x106 CAR T cells, n=7; cohort 3: 800x106 CAR T cells, n=7) in 20 heavily pre-treated R/R MM patients. Grade 1-2 cytokine release syndrome (CRS) was reported in 18 patients (90%). Neither grade 3-4 CRS nor neurotoxicity of any grade were observed. No dose-limiting toxicities were observed in any cohort. The overall response rate (ORR), (stringent) complete response (CR/sCR), and very good partial response rates were 75%, 50%, and 25%, respectively. Response rates were dose-dependent with 85% ORR, 71% CR, and 57% minimal residual disease negativity in the high-dose cohort 3. Across all cohorts, the median overall survival (OS) was 308 days (range 25-466+), with an estimated OS of 55% as of June 27th (data cut-off). The median progression-free survival was 160 days, with 6 subjects remaining progression free at the time of data cut-off. Our findings demonstrate the manageable safety profile and efficacy of HBI0101. These encouraging data support the decentralization of CAR T production in an academic setting, ensuring sufficient CAR T supply to satisfy the increasing local demand.

Successful treatment with plasma exchange in life-threatening hyperhemolytic syndrome unrelated to sickle cell disease.

INTRODUCTION: Hyperhemolytic syndrome (HHS) is a severe form of delayed transfusion reaction primarily described in sickle cell anemia patients which is characterized by a hemoglobin decrease to pre-transfusion levels or lower, often with reticulocytopenia and no evidence of auto- or allo-antibodies. CASE PRESENTATION: We present two cases of severe HHS in patients without sickle cell anemia refractory to treatment with steroids, immunoglobulins, and rituximab. In one case, temporary relief was achieved with eculizumab. In both cases, plasma exchange resulted in a profound and immediate response allowing for splenectomy and resolution of hemolysis. DISCUSSION/CONCLUSION: We discuss the pathophysiology of HHS, its presentation and treatment and expand on the possible role of plasma exchange in this setting.

Comparing end-of-life care of hematologic malignancy versus solid tumor patients in a tertiary care center.

OBJECTIVES: To compare end-of-life (EOL) care for solid tumor and hematologic malignancy (HM) patients. METHODS: We collected data on the last 100 consecutive deceased HM and 100 consecutive deceased solid tumor patients who died prior to June 1st 2020, treated at a single center. We compared demographic parameters, cause of death as ascertained by review of medical records by two independent investigators, and EOL quality indicators including: place of death, use of chemotherapy or targeted/biologic treatment, emergency department visits as well as hospital, inpatient hospice and Intensive Care Unit admissions and the time spent as inpatient over the last 30 days of life; mechanical ventilation and use of blood products during the last 14 days of life. RESULTS: In comparison with solid tumor patients, HM patients more commonly died from treatment complications (13% vs. 1%) and unrelated causes (16% vs. 2%, p < .001 for all comparisons). HM patients died more frequently than solid tumor patients in the intensive care unit (14% vs. 7%) and the emergency department (9% vs. 0%) and less frequently in hospice (9% vs. 15%, p = .005 for all comparisons). In the 2 weeks prior to death HM patients were more likely than solid tumor patients to undergo mechanical ventilation (14% vs. 4%, p = .013), receive blood (47% vs. 27%, p = .003) and platelet transfusions (32% vs. 7%, p < .001); however, no statistical difference was found in use of either of chemotherapy (18% vs. 13%, p = .28) or targeted treatment (10% vs. 5%, p = .16). CONCLUSIONS: HM patients were more likely than solid tumor patients to undergo aggressive measures at EOL. Rarity of HM deaths, frequently caused by complications of treatment and unrelated causes, may affect treatment choices at EOL.

Risk factors and outcomes of COVID-19 in adult patients with hematological malignancies: A single-center study showing lower than expected rates of hospitalization and mortality.

BACKGROUND: Studies addressing coronavirus disease 2019 (COVID-19) in patients with hematological malignancies have reported mortality rates of up to 40%; however, included predominantly hospitalized patients. METHODS: During the first year of the pandemic, we followed adult patients with hematological malignancies treated at a tertiary center in Jerusalem, Israel, who contracted COVID-19, with the aim of studying risk factors for adverse COVID-19-related outcomes. We used remote communication to track patients managed at home-isolation, and patient questioning to assess the source of COVID-19 infection, community versus nosocomial. RESULTS: Our series included 183 patients, median age was 62.5 years, 72% had at least one comorbidity and 39% were receiving active antineoplastic treatment. Hospitalization, critical COVID-19, and mortality rates were 32%, 12.6%, and 9.8%, respectively, remarkably lower than previously reported. Age, multiple comorbidities, and active antineoplastic treatment were significantly associated with hospitalization due to COVID-19. Treatment with monoclonal antibodies was strongly associated with both hospitalization and critical COVID-19. In older (≥60) patients not receiving active antineoplastic treatment, mortality, and severe COVID-19 rates were comparable to those of the general Israeli population. We did not detect patients that contracted COVID-19 within the Hematology Division. CONCLUSION: These findings are relevant for the future management of patients with hematological malignancies in COVID-19-affected regions.

Venetoclax-based salvage therapy for adult patients with relapsed/refractory acute lymphoblastic leukemia.

OBJECTIVES: Dysregulation of BCL-2 family members has been reported in acute lymphocytic leukemia (ALL), with various BH3-dependencies of the leukemic clone. We conducted a multicenter retrospective cohort of patients with relapsed/refractory B or T ALL, with ven-chemotherapy or ven-navitoclax combinations, to assess efficacy and safety. METHODS: Seventeen patients were included in the analysis, median age was 32 years, with 6 B-ALL and 11 T-ALL patients. Nine patients received venetoclax combined with chemotherapy, and 13 patients received venetoclax in combination with navitoclax, vincristine and asparaginase, of which 5 were already exposed to venetoclax in previous lines. RESULTS: ORR was 55% and 46% among the ven-chemotherapy and the ven-navitoclax-chemotherapy, respectively. Most of the responders proceeded to an allogenic bone marrow transplant in both cohorts. The most common adverse effects of the ven-navitoclax combination were infectious complications and hepatotoxicity. CONCLUSIONS: Our data demonstrated the possible efficacy of ven-chemotherapy and ven-navitoclax in r/r ALL with moderate toxicity.

Utility of Galactomannan Screening for Early Detection of Invasive Aspergillosis in High-Risk Hemato-Oncology Patients.

INTRODUCTION: Invasive aspergillosis (IA) affects mainly patients with hematological malignancies, and early diagnosis is crucial for timely treatment. Most diagnoses are based on clinical and mycological criteria, mostly galactomannan (GM) test in serum or bronchoalveolar fluid, which is performed in case of clinical suspicion or as routine screening in patients at high risk who are not receiving anti-mold prophylaxis, for early detection of IA. The aim of this study was to assess in a real-world setting the efficacy of biweekly serum GM screening for the early detection of IA. METHODS: A retrospective cohort that included 80 adult patients treated at the Hematology Department, Hadassah Medical Center, 2016-2020, with a diagnosis of IA. Clinical and laboratory data were collected from patients' medical files and the rate of GM-driven, GM-associated, and non-GM-associated IA was calculated. RESULTS: There were 58 patients with IA. The rate of GM-driven diagnosis was 6.9%, GM-associated diagnosis was 43.1%, and non-GM-associated diagnosis was 56.9%. The GM test as a screening tool had led to IA diagnosis in only 0.2% of screened serums with a number needed to screen in order to find 1 patient with IA of 490. CONCLUSION: Clinical suspicion outweighs GM screening as a tool for early diagnosis of IA. Nevertheless, GM has an important role as a diagnostic tool for IA.

Polarization in public attitudes toward end-of-life decisions in Israel - A cross-sectional study.

OBJECTIVES: End-of-life (EoL) processes are a complex socio-normative and ethical phenomenon. This study aimed to generate a database of public opinion in Israel concerning EoL processes and decisions and to identify differences in attitudes across subgroups in the population, particularly based on experience as a family caregiver of a dying patient. METHODS: This cross-sectional study was performed in late March 2022. The study utilized an online sample of 605 adults over the age of 50 including those who accompanied a loved one to their death in the last 3 years. Participants were requested to provide their opinions and attitudes on several aspects of EoL decisions, including truth-telling, medically assisted dying, EoL procedures, pre-death actions, and family caregivers' engagement. RESULTS: While only 27% and ∼30% of participants support artificial respiration or feeding (respectively) of terminally ill patients, 66% support analgesic treatment, even at the risk of shortening life. The data show an association between religiosity and agreement with life-extending procedures. For example, while 83% of seculars support medically assisted dying, only 59% and 26% of traditional and religious respondents support it. However, no statistically significant differences were observed in support of family involvement in EoL process in any sociodemographic variable. SIGNIFICANCE OF RESULTS: The results of this study suggest that the Israeli public is relatively polarized on several issues about EoL processes, specifically patient autonomy and medically assisted dying. Yet, at the same time, there is a consensus among the Israeli public about certain EoL elements, particularly the importance of family caregivers in the EoL decision-making process.

Agencies Displayed by Patients, Medical Teams, and Caregivers at the End of Life from the Perspectives of Family Members - A Qualitative Study.

Background: End-of-life (EoL) Care is challenging for terminally-ill patients and their caregivers. This research is aimed to examine the relational agencies of the patients, the caregivers, and the medical teams in the context of EoL care, with a particular emphasis on the caregivers. Methods: This study is based on the qualitative analysis of interviews with 12 individuals who were closely supported a loved one to their death from a terminal illness. Results: Information collected revealed several agency-related themes. Family caregivers are significant entities in managing the 'case' of a seriously ill individual. At the final or more advanced stages of the EoL process, caregivers gradually shift from a supportive role to being active agents, but not always backed by the necessary experience, knowledge, or the requisite emotional resilience. Conclusions: Based on recognizing their agentic proactivity, a clear and elaborate articulation of the family caregivers' roles is needed.

Early integration of palliative care for patients with haematological malignancies.

Early palliative care (EPC) significantly improves quality of life, symptoms, and satisfaction with care for patients with advanced cancer. International organizations have recognized and promoted the role of palliative care as a distinct specialty, advocating its involvement throughout the cancer trajectory. Although patients with haematologic malignancies (HMs) have a comparable symptom burden to patients with solid tumours, they face multiple barriers to EPC integration. In this review, we discuss these barriers, present updated evidence from clinical trials of EPC in HMs and propose models to support EPC integration into care for patients with HMs.

The Emerging Role of Venetoclax-Based Treatments in Acute Lymphoblastic Leukemia.

Venetoclax, a B-cell lymphoma (BCL-2) inhibitor, in combination with hypomethylating agents has become the new standard of care in elderly and unfit patients with acute myeloid leukemia, with significantly improved overall survival and quality of life. Studies of venetoclax combined with high-dose chemotherapy are emerging with evidence of higher rates of molecular remission. Recently, a growing number of publications bring forth the use of venetoclax in patients with acute lymphoblastic leukemia (ALL). In the current review, we present the biological rationale of BCL-2 inhibition in ALL, how the interplay of BH3 proteins modulate the response and the current clinical experience with various combinations.

[CASE REPORT: LEGAL, PSYCHOLOGICAL AND ETHICAL ASPECTS OF THE DYING PATIENT ACT].

INTRODUCTION: We present a patient with amyotrophic lateral sclerosis (ALS), dependent on noninvasive ventilation, whose advance directives precluded life-prolonging measures. The patient was found in cardiac arrest and in accordance with the directives of her surrogate decision maker, underwent intubation and mechanical ventilation. Later, an additional surrogate decision maker disapproved of ventilation and when the ventilator was disconnected for bronchial suctioning, she asked the nurse not to reconnect the patient to the ventilator. We discuss the legal, psychological and ethical aspects of implementation of Israeli law in this complex patient.

Chronic demodicosis in patients with immune dysregulation: An unexpected infectious manifestation of Signal transducer and activator of transcription (STAT)1 gain-of-function.

Signal transducer and activator of transcription (STAT)1 heterozygous gain-of-function (GOF) mutations are known to induce immune dysregulation and chronic mucocutaneous candidiasis (CMCC). Previous reports suggest an association between demodicosis and STAT1 GOF. However, immune characterization of these patients is lacking. Here, we present a retrospective analysis of patients with immune dysregulation and STAT1 GOF who presented with facial and ocular demodicosis. In-depth immune phenotyping and functional studies were used to characterize the patients. We identified five patients (three males) from two non-consanguineous Jewish families. The mean age at presentation was 11.11 (range = 0.58-24) years. Clinical presentation included CMCC, chronic demodicosis and immune dysregulation in all patients. Whole-exome and Sanger sequencing revealed a novel heterozygous c.1386C>A; p.S462R STAT1 GOF mutation in four of the five patients. Immunophenotyping demonstrated increased phosphorylated signal transducer and activator of transcription in response to interferon-α stimuli in all patients. The patients also exhibited decreased T cell proliferation capacity and low counts of interleukin-17-producing T cells, as well as low forkhead box protein 3+ regulatory T cells. Specific antibody deficiency was noted in one patient. Treatment for demodicosis included topical ivermectin and metronidazole. Demodicosis may indicate an underlying primary immune deficiency and can be found in patients with STAT1 GOF. Thus, the management of patients with chronic demodicosis should include an immunogenetic evaluation.

Predictors of death at home among cancer patients in Israel: a population-based study.

BACKGROUND: Most cancer patients prefer to die at home; however, many die in hospital. The aim of the current study is to elucidate the association between dying at home and various personal factors in the Israeli population of cancer patients. METHODS: Data on cancer incidence (2008-2015) and death (2008-2017) was provided by the Israeli Central Bureau of Statistics and the Israel National Cancer Registry. Binary logistic regression analyses were performed to assess odds ratios for death at home following cancer diagnosis while controlling for age, sex, ethnicity, years of education, residential socioeconomic score, and time from diagnosis. We also assessed the relation between place of death and specific cancer sites, as well as the time trend from 2008 to 2017. RESULTS: About one quarter (26.7%) of the study population died at home. Death at home was most frequent among patients diagnosed with brain tumors (37.0%), while it was the lowest among patients with hematologic malignancies (lymphoma and leukemia, 20.3 and 20.0%, respectively). Rates of dying at home among patients with residential socioeconomic scores of 1, 2-9, and 10 were about 15, 30, and 42.9%, respectively. In patients from the 4th to the 7th decades of life, rates of death at home increased at a linear rate that increased exponentially from the 8th decade onwards. After controlling for potential confounders, predictive variables for death at home included age (OR = 1.020 per year, 95% CI 1.017-1.024), male sex (OR = 1.18, 95% CI 1.077-1.294), years of education (OR = 1.029 per year, 95% CI 1.018-1.040), and time from diagnosis (OR = 1.003 per month, 95% CI 1.001-1.005 all p < 0.001). No trend was seen from 2008 to 2013, while from 2014 to 2017 a slight increase in the rate of death at home was seen each year. CONCLUSIONS: These results indicate wide variability in death at home exists among patients of different ages, sex, education, socioeconomic status and time from diagnosis. These findings stress the importance of delivering quality palliative care at home, mainly for patients with hematologic malignancies, younger patients, and patients of very low socioeconomic status. Understanding the complex mechanisms whereby patient preferences and the above variables may determine the preferred place of death remains an important research priority.

Willingness and concerns of transfusion-dependent hematological patients toward the option of home transfusion therapy.

BACKGROUND: One of the main obstacles of providing home-based palliative care to transfusion-dependent hematology patients is the lack of home transfusions services. While healthcare professionals are concerned with safety and cost of home transfusions, the attitude of the patients toward home transfusions are mostly unknown. AIM: To obtain quantitative data regarding the willingness and concerns of transfusion-dependent patients with hematological diseases toward the option of home transfusions. DESIGN: A cross sectional survey including a self-administered questionnaire in one of the three main spoken languages in Israel was administered to patients in 17 hospital hematology outpatient clinics between May 2019 and March 2020. RESULTS: About 52% of 385 patients that participated in the survey preferred home transfusions to hospital transfusions. Gender, age, education, or type of disease were not associated with preference for home transfusions, nor were hospital location or its size. The likelihood to prefer home transfusions was significantly higher among the Hebrew-speakers and those who had not experienced adverse effects previously. The most significant factor associated with preference of home transfusions was a perceived negative effect of hospital-based transfusion on quality of life. The main reason to reject home transfusions was fear of possible adverse effects and concerns over losing contact with the medical staff at the treating hospital. CONCLUSION: These data suggest that a significant portion of transfusion-dependent patients in Israel view home transfusions as a preferred treatment option and that its successful implementation requires maintaining ongoing contact with the treating hospital.

Attitudes toward death and death acceptance among hemato-oncologists: An Israeli sample.

OBJECTIVE: Hemato-oncologists are highly exposed to patients' death and suffering during their daily work. The current exploratory and cross-sectional study examined death acceptance attitudes, in order to explore whether death acceptance attitudes are associated with fear of death. METHOD: A convenience sample of 50 Israeli hemato-oncologists currently working in a clinical setting participated in the study. They completed the Death Attitudes Profile revised questionnaire (DAP-R), which examines levels of fear of death, death avoidance, approach acceptance, neutral acceptance, and escape acceptance. In addition, the hemato-oncologists reported on levels of exposure to patients' death and suffering. RESULTS: A repeated measures MANOVA revealed significantly lower levels of neutral acceptance, compared with approach and escape acceptance. Path analysis for predicting fear of death by the other study variables revealed that death avoidance fully mediated the relationship between approach acceptance and fear of death as well as revealing a negative correlation between neutral acceptance and fear of death (higher neutral acceptance was related to lower fear of death). No associations were found between exposure to death and suffering and attitudes toward death. SIGNIFICANCE OF RESULTS: In contrast to previous conceptualizations, the ability to adaptively cope with fear of death differed in accordance with death acceptance attitudes. Whereas neutral acceptance adaptively defended from fear of death, approach acceptance was associated with increased fear of death through death avoidance. As hemato-oncologists are highly exposed to patients' death and suffering, and are required to make critical medical decisions on daily basis, these findings may have substantial implications for end-of-life care and the process of medical decision-making regarding the choice of treatment goals: cure, quality of life, and life prolongment. Further research is needed to investigate the role of death acceptance attitudes among hemato-oncologists.

Ixazomib-based regimens for relapsed/refractory multiple myeloma: are real-world data compatible with clinical trial outcomes? A multi-site Israeli registry study.

Ixazomib, the first oral proteasome inhibitor (PI), has been approved for the treatment of relapsed refractory multiple myeloma (RRMM) in combination with lenalidomide and dexamethasone, based on the TOURMALINE-MM1 phase 3 trial, which demonstrated the efficacy and safety of this all-oral triplet, compared with lenalidomide-dexamethasone. However, clinical trial outcomes do not always translate into real-world outcomes. The aim of this study was to assess the outcomes of ixazomib-based combination for treatment of patients with RRMM in a real-world setting. All consecutive RRMM patients who received at least one cycle of ixazomib-based treatment combination between June 2013 and June 2018 were identified. Data was extracted from medical charts focusing on demographics, disease characteristics, prior treatment, and responses. Primary endpoint was progression-free survival (PFS); secondary endpoints included overall response rate (ORR), overall survival (OS), safety, and tolerability. A total of 78 patients across 7 sites were retrospectively included. Median follow-up was 22 months. Median age was 68 (range 38-90). Sixty-four percent received ixazomib in 2nd line, 19% in 3rd line. Overall, 89% of patients had been exposed to PIs (bortezomib 87%) prior to IRd, 41% to IMiDs. Twenty-nine (48%, of 60 available) had high (t(4:14), t(14:16), del17p) or intermediate (+1q21) risk aberrations. Most patients (82%) received ixazomib in combination with lenalidomide and dexamethasone. An exploratory assessment for disease aggressiveness at diagnosis was classified by a treating physician as indolent (rapid control to protect from target organ damage not required) vs aggressive (imminent target organ damage) in 63% vs 37%, respectively. Treatment was well tolerated, with a low discontinuation rate (11%). Median PFS on ixazomib therapy was 24 months (95% CI 17-30). PFS was 77% and 47% at 12 and 24 months, respectively. Median OS was not reached; OS was 91% and 80% at 12 and 24 months, respectively. Higher LDH, older age, and worse clinical aggressiveness were associated with worse PFS, whereas a deeper response to ixazomib (≥ VGPR) and a longer response to first-line bortezomib (≥ 24 m) were associated with an improved PFS on ixazomib. No effect on PFS was found for cytogenetic risk by FISH, ISS/rISS, and prior anti-myeloma treatment. Ixazomib-based combinations are efficacious and safe regimens in RRMM patients in the real-world setting, regardless to cytogenetic risk, with a PFS of 24 months comparable with clinical trial data. This regimen had most favorable outcomes among patients who remained progression-free more than 24 months after a bortezomib induction and for those who have a more indolent disease phenotype.

Real-world data on incidence, clinical characteristics and outcome of patients with macrofocal multiple myeloma (MFMM) in the era of novel therapies: A study of the Greco-Israeli collaborative myeloma working group.

We investigated incidence, characteristics and outcome of patients with macrofocal multiple myeloma (MFMM) treated mainly with novel therapies. Based on definition (BMPCs <20% and lytic lesions/plasmacytomas, without anemia, renal insufficiency or hypercalcemia) we identified 140 patients with MFMM, among 4650 myeloma patients (3%). Twice the number of patients with typical myeloma were used as controls; 60% were <65 years and 70% had advanced bone disease. Plasmacytomas were more frequent in MFMM compared with standard myeloma (68% vs 15%, P < .05). Adverse prognostic parameters (high lactate dehydrogenase, advanced stage, high risk cytogenetics, immunoparesis) were less common in patients with MFMM compared with controls (P < .05); 90% received novel agents and 47% underwent autologous transplantation upfront; 90% achieved an objective response; 70% had at least very good partial response which was significantly higher compared with controls (P < .05). After a median follow-up of 52 months, 33 patients have died. Early death (<12 months) was infrequent in MFMM. Median progression-free survival and overall survival (OS) were 46 and 129 months respectively, both significantly longer compared with controls (P < .001). Proteasome inhibitor (PI)-based therapy was the only independent predictor for OS in the multivariate analysis (HR: 3.9; P < .001). In conclusion, MFMM is a distinct entity presented in young and elderly subjects, characterized by limited bone marrow infiltration, advanced bone disease and frequent presence of plasmacytomas; MFMM patients have less often adverse prognostic features and achieve excellent responses and prolonged OS especially when treated with PI-based therapies. Novel imaging will help in a more accurate classification of this entity.

Frontline treatment with the combination obinutuzumab ± chlorambucil for chronic lymphocytic leukemia outside clinical trials: Results of a multinational, multicenter study by ERIC and the Israeli CLL study group.

In recent years, considerable progress has been made in frontline therapy for elderly/physically unfit patients with CLL. The combination of obinutuzumab and chlorambucil (O-Clb) has been shown to prolong progression free survival (PFS, median PFS-31.5 months) and overall survival (OS) compared to chlorambucil alone. More recently, obinutuzumab given in combination with either ibrutinib or venetoclax improved PFS but not OS when compared to O-Clb. In this retrospective multinational, multicenter co-operative study, we evaluated the efficacy and safety of frontline treatment with O ± Clb in unfit patients with CLL, in a "real-world" setting. Patients with documented del (17p13.1)/TP53 mutation were excluded. A total of 437 patients (median age, 75.9 years; median CIRS score, 8; median creatinine clearance, 61.1 mL/min) were included. The clinical overall response rate was 80.3% (clinical complete and partial responses in 38.7% and 41.6% of patients, respectively). Median observation time was 14.1 months and estimated median PFS was 27.6 months (95% CI, 24.2-31.0). In a multivariate analysis, high-risk disease [del (11q22.3) and/or IGHV-unmutated], lymph nodes of diameter > 5 cm, obinutuzumab monotherapy and reduced cumulative dose of obinutuzumab, were all independently associated with shorter PFS. The median OS has not yet been reached and estimated 2-year OS is 88%. In conclusion, in a "real-world" setting, frontline treatment with O-Clb achieves PFS comparable to that reported in clinical trials. Inferior outcomes were noted in patients with del (11q22.3) and/or unmutated IGHV and those treated with obinutuzumab-monotherapy. Thus, O-Clb can be still considered as legitimate frontline therapy for unfit CLL patients with low-risk disease.

Romidepsin-Bendamustine Combination for Relapsed/Refractory T Cell Lymphoma.

BACKGROUND: The treatment of relapsed/refractory (R/R) peripheral T cell lymphoma (PTCL) is limited to a few agents. Romidepsin, a histone deacetylase inhibitor, was approved for PTCL treatment as a single agent in the R/R setting, yet with partial efficacy. Several attempts to combine romidepsin with other chemotherapy regimens have been reported, however, with significant toxicity. OBJECTIVES: To study the romidepsin-bendamustine combination in PTCL in an attempt to maximize efficacy while minimizing toxicity. METHODS: We report on a series of 7 heavily pretreated PTCL patients (2-5 previous lines of therapy) treated with a romidepsin-bendamustine combination. RESULTS: Four patients were not previously exposed to either drug. Of these, 2 achieved complete remission. Interestingly, 1 patient continued treatment with a prolonged progression-free survival of more than 4 years. Toxicity was minimal and no treatment-related deaths or discontinuation were noted. Significant nausea and vomiting were reported in over 50% of patients. Hematological toxicity was mild and lower than that reported for other romidepsin-chemotherapy combinations and was correlated with bone marrow involvement by lymphoma. CONCLUSIONS: Although reporting a small number of patients, our data suggest that the combination of romidepsin and bendamustine may be a feasible therapeutic option in R/R PTCL patients and merits further study.
