The use of novel small molecule inhibitors alone or in combination with anti-CD20 monoclonal antibodies for chronic lymphocytic leukemia (CLL) has raised a number of questions on efficacy, tolerability, long-term treatment adherence in patients with heterogeneous clinical features. To fill this gap, we designed a study focusing on treatment sequencing in patients with CLL in order to (i) compare the outcome of patients treated with chemoimmunotherapy (CIT) combinations in first-line versus those receiving Bruton's tyrosine kinase inhibitors (BTKi); (ii) characterize the efficacy and tolerability of venetoclax-based regimens; (ii) understand the impact of treatment sequencing when it comes to chemo-free options including venetoclax after BTKi and vice versa. Data from consecutive sets of patients diagnosed with CLL between 2000-2020 attended at 77 institutions affiliated with ERIC were collected and analyzed. Collected variables included: demographics, clinical stage at diagnosis, IGHV gene somatic hypermutation status; cytogenetic status for chromosomes 11q, 13q 17p and 12 determined by fluorescence in situ hybridization; TP53 gene mutation status; treatment; treatment response; discontinuation; reason for discontinuation; death. We included 9173 patients with a diagnosis of CLL who received at least one line of treatment. The median age at diagnosis was 67 years with a male:female ratio of 1.9. The median follow-up was 78 months (IQR, 48-120 months). Regarding novel targeted agents, 1860/9173 (20.2%) patients had received at least one line of treatment with BTKi (ibrutinib, n=1788; acalabrutinib, n=72) over the disease course; 631/9173 (6.9%) with venetoclax; and, 447/9173 (4.9%) with the PI3K inhibitor idelalisib. Seventy-nine patients were treated with both BTKi and venetoclax (59 BTKi followed by BCL2i, 20 vice versa). At last follow-up, 5870/9173 patients (64.0%) were alive, 3229/9173 (35.2%) died and 74/9173 (0.8%) were lost to follow-up. Patients treated with BTKi in first-line were enriched for TP53 aberrations [del(17p) 27.6%, TP53 mutation 26.3%] and unmutated IGHV genes (69%) and obtained an ORR of 87.7%. Of these, 136 (26.3%) discontinued treatment after a median of 1.2 years (0.07-5.98); main reasons of discontinuation were toxicity (40.5%) and failure (26.2%). Among 631 patients treated with venetoclax at any line, 100 (15.8%) received BCL2 +/- anti-CD20 as first-line; 170 (26.9%) as second line (125 previously treated with CIT, 27 with BTKi); and, 361 as third or subsequent line. ORR ranged between 71.5% (≥3 lines) with 30.5% CR/CRi to 90.3% (first-line) with 68.1% CR/CRi. Treatment discontinuation was due to toxicity in 28.6% of patients treated in the first-line, and 17.6% and 21.8% of patients treated in second and third-or-higher-line, respectively. Disease progression led to treatment discontinuation in 14.3%, 20.6% and 33.6% in first, second and third-or-higher line, respectively. CIT was used as front-line treatment in 5465 patients (59.6%). Of these, 2070 (37.9%) and 1018 (18.6%) patients received a second and third line of treatment, respectively. The great majority (865/1086 cases, 79.7%) of patients who received a second line before 2014 were retreated with CIT, most commonly Bendamustine-Rituximab (284/1086, 26.1%) and Fludarabine-Cyclophosphamide-Rituximab (252/1086, 23.2%); alemtuzumab monotherapy was used in 55/1086 (5%) of patients. After 2014, 415/984 patients (42.1%) were retreated with BTKi; 93 (9.5%) with venetoclax; 70 (7.2%) with idelalisib; 50 (5%) with Alemtuzumab monotherapy, and 315 (32%) with CIT. Similarly, in the third-or-higher line of treatment, most patients (86.3%) were retreated with CIT before 2014, while BTKi, BCL2i, and PI3Ki were mainly used after 2014 (in 43.1%, 15.7% and 14.7% of cases, respectively). Finally, our cohort included 1075 patients with TP53 aberrations. The ORR of patients receiving BTKis (n=171) as first-line of treatment was 86.5% (22.2 CR+64.3 PR), while the ORR with venetoclax +/- anti-CD20 (n=15) was 91% (45.5% CR+45.5 PR). Patients treated with CIT (n=694) had an ORR of 68.7% (28.3% CR+40.4% PR). In conclusion, in a large international study we provide real world data regarding the selection and sequencing of treatment in CLL, charting a major shift in treatment patterns before and after the introduction of novel trargeted agents and confirming their efficacy even in high-risk CLL.

In this overview we present a summary of evidence from systematic reviews (SRs) on the safety and efficacy of carfilzomib in multiple myeloma (MM). Our search in electronic databases and conference proceedings yielded 14 eligible SRs, graded as of low overall quality with the AMSTAR-2 tool. The Corrected Covered Area index was 52.3% which shows very high overlap among studies. Carfilzomib was shown to increase progression free survival (HR=0.61, 95%CI=0.47-0.78, p = 0.01, I

Background/Aim: Primary mediastinal large B-cell lymphoma (PMLBCL) is an aggressive B-cell non-Hodgkin lymphoma (NHL), whose prognosis has greatly improved since the incorporation of the anti-CD20 monoclonal antibody rituximab into current therapeutic regimens. Evidence, however, on the optimal time interval between consecutive chemoimmunotherapy (CIT) cycles is still scarce. This study aimed to evaluate the efficacy outcomes of the more commonly administered 3-weekly regimens to the biweekly ones in a PMLBCL patients’ population, who were mostly treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone every 21 days (R-CHOP-21) or R-CHOP-14. Patients and Methods: We retrospectively studied our cohort of consecutively treated PMLBCL patients, focusing on their treatment density, in order to determine possible differences in treatment outcomes. Results: CIT, in the form of both R-CHOP-21 as well as R-CHOP-14 (or similar regimens), is highly active in PMLBCL, with low rates of early treatment failure. In our cohort of patients, R-CHOP-14 did not result in a meaningful improvement of freedom from progression (FFP) or overall survival (OS). Conclusion: Both R-CHOP-14 and R-CHOP-21 are probably equally effective in PMLBCL, yet further, prospective, randomized studies are warranted to clarify whether dose-dense regimens can be associated with better disease control and long-term results.

A previously healthy 3-year-old boy presented with pallor, jaundice, cyanosis, and a 24-hour history of vomiting and anorexia following fava bean ingestion. Clinical examination and laboratory findings were consistent with severe nonimmune hemolytic anemia with methemoglobinemia. Given the patient's history, a previously unrecognized glucose-6-phosphate dehydrogenase deficiency was suspected and diagnosed. The aim of this article is to delineate the possible coexistence of methemoglobinemia and glucose-6-phosphate dehydrogenase deficiency in children presented with acute hemolysis and discuss its management while reviewing the existing literature.

Lymphomas are the most common hematological malignancies and are further distinguished in Hodgkin lymphoma (HL) and non-Hodgkin (NHL). For staging purposes and for assessing response to treatment, the Lugano classification is currently used, both for HL and NHL patients, whereas for the assessment of prognosis, several prognostic systems exist, such as the international prognostic index (IPI) and revised-IPI for diffuse large B cell lymphomas, follicular lymphoma IPI (FLIPI)-1 and 2 for follicular lymphomas, and the international prognostic score for advanced HL. The aim of this systematic review was to determine the significance of the metabolic FDG PET/CT parameters, such as metabolic tumor volume (MTV) and total lesion glycolysis (TLG), in monitoring therapeutic interventions and prognostic outcome of patients with HL and NHL. We performed a systematic search on the literature and selection of articles concerning treatment evaluation, response and survival in association with MTV and TLG in patients with lymphomas. Our review documented that in most studies, baseline MTV and TLG were predictive of treatment response, progression-free survival (PFS) and overall survival (OS) for both HL and NHL patients. There were conflicting results for the value of interim determination of MTV and TLG. Our conclusion was that combination of baseline MTV and TLG parameters with prognostic scoring systems, such as IPI, or FLIPI-1 and -2, will add additional predictive power for response and prognosis in lymphoma patients.

The regimen of 5-azacytidine for patients with myelodysplastic syndrome (MDS) has remained unchanged since its first approval. Although several modifications have since been made and delays and dose reductions are common especially during the first treatment cycles, there are minimal data on the prognostic effect of these modifications. In this study, based on data from 897 patients with MDS treated with 5-azacytidine recorded in a national registry, the effect of treatment delays and dose reductions on response, transformation to acute myeloid leukaemia, and survival (after 5-azacytidine initiation, OST ) were analysed. Delays during the first two cycles were noted in 150 patients (16·7%) and were found to adversely affect OST independently of the International Prognostic Scoring System score [hazard ratio (HR), 1·368; P = 0·033] or pre-existing neutropenia (HR, 1·42; P = 0·015). In patients achieving a response, delays before response achievement were correlated with its type (complete remission, 2·8 days/cycle; partial remission, 3·3 days/cycle; haematologic improvement, 5·6 days/cycle; P = 0·041), while delays after response achievement did not have any effect on retention of response or survival. Dose reductions were found to have no prognostic impact. Based on our results, treatment delays especially during the first cycles should be avoided, even in neutropenic patients. This strict strategy may be loosened after achieving a favourable response.

Cardiovascular disease (CVD) emerges as a major cause of death in patients with myelodysplastic syndrome (MDS), but predictors of fatal CVD and the effect of MDS-specific treatments on CVD mortality remain largely unknown. In an analysis involving 831 patients with MDS with known causes of death, we noted an independent association of lower risk MDS, age70 years, pre-existing CVD, and treatment with erythropoiesis-stimulating agents with a higher risk of death from CVD. If externally validated, these simple risk factors could increase clinicians' awareness toward CVD complications and guide early introduction of intensive monitoring and preventive interventions in MDS patients.

Background Hypomethylating agents have altered the prognosis of myelodysplastic syndrome (MDS) so that long-term survival is now a feasible treatment goal. Patients and Methods We analyzed data from patients with MDS treated with 5-azacytidine recorded in the Hellenic 5-azacytidine registry. We divided patients, on the basis of their survival after 5-azacytidine initiation (OST), in groups of long-term survivors (Q3 and P90 group with OST above the third quartile and the 90th percentile of the whole group, respectively) and short-term survivors comprising the remaining patients, and compared the characteristics between the groups. The study included 626 patients, 157 in the Q3 group and 63 in the P90 group. Results Categorization per the International Prognostic Scoring System (IPSS), revised IPSS (IPSS-R), and World Health Organization–based prognostic scoring system (WPSS) was found to predict long-term survival, while multivariate analysis revealed that response to 5-azacytidine was the strongest predictor of long-term survival. Nevertheless, patients with hematologic improvement (HI) and stable disease (SD) were equally distributed in the groups of short- and long-term survival. Conclusion SD should not be considered a poor treatment response and should not be grouped with failure, while HI offers similar prognosis to SD and thus should not be grouped with complete and partial remission. Patients with SD should continue treatment with 5-azacytidine.

Autophagy and cellular senescence are interrelated cellular stress responses important for cellular homeostasis and they have been implicated in the pathogenesis of classical Hodgkin lymphoma (cHL). However, the presence of autophagy and cellular senescence and their relation with clinical and laboratory parameters needs further elucidation. Thus, autophagy (LC3B and p62 immunohistochemical expression) and cellular senescence (p16 immunohistochemical expression and SenTraGor™ staining) were studied in tissue sections from 59 patients with cHL. Autophagy and cellular senescence-associated markers were detected in variable proportions of Hodgkin and Reed-Sternberg (HRS) cells in cHL cases. High nuclear p62 immunohistochemical expression in HRS cells showed significant positive correlation with relapse of the disease (p = 0.037). Heterogeneous autophagy and cellular senescence patterns were revealed in HRS cells suggesting biological heterogeneity of cHL. The detection of high nuclear p62 expression in HRS cells may identify a subset of cHL with more aggressive clinical behavior.

Thrombocytopenia may be associated with a variety of conditions and risks depending on its severity, ranging from mild epistaxis to life-threating bleeding. Many drugs or herbal remedies can cause thrombocytopenia by either inhibiting platelet production and/or enhancing their destruction from the peripheral blood mediated via an immunological mechanism implicating drug-dependent antibodies. The latter entity is called drug-induced immune thrombocytopenia: a life-threatening, under-recognised condition, which is often a diagnostic challenge. Rifampicin is a widely used, well-tolerated, and effective bactericidal drug. Adverse events, except for gastrointestinal effects, headache, skin rash, and pruritus, are uncommon. The authors herein report on a patient with isolated thrombocytopenia with a recent medical history of brucellosis on rifampicin and doxycycline. Thrombocytopenia was proved to be rifampicin-induced. Also presented is a short review of the literature on this rare subject, which should be of great importance to clinicians.

CD56 or neural cell adhesion molecule (NCAM) is a membrane glycoprotein expressed on neural cells, muscle tissues and myeloma cells. Expression of CD56 has been studied in patients with multiple myeloma (MM) with controversial results. The scope of this study was to examine the expression of CD56 in MM patients at diagnosis and investigate its association with clinicopathologic parameters. We retrospectively collected and analyzed data from 109 patients with MM diagnosed over the last decade (January 2010 to June 2020). Expression of CD56 was assessed by immunohistochemistry in bone marrow biopsies and investigated its association with a variety of clinicopathological parameters. For the statistical analysis χ2 test and Mann-Whitney U tests were used to compare categorical and continuous variables in CD56+ and CD56- patients, respectively. Statistical analysis was performed using SPSS 21.0 for Windows (SPSS, Chicago, IL). Based on the expression of CD56 the patient population was divided to CD56+ patients and CD56- patients; Sixty-eight patients were CD56 + and 41 patients were CD56–. Absence of CD56 expression was associated with unfavorable prognostic parameters such as elevated lactate dehydrogenase (LDH) and β2-microglobulin levels, advanced stage according to the International Staging System (ISS) and clonal bone marrow plasma cell infiltration ≥ 60%, but no effect on outcome, while the expression of CD56 was associated with well differentiated neoplastic plasma cells. Our study confirmed that lack of CD56 expression is a possible marker of poor prognosis in patients with MM. The detection of CD56 expression by either immunohistochemistry or flow cytometry is simple and cheap, and it could be incorporated in future prognostic or predictive scores. Prospective studies are needed in order to evaluate the role of expression of CD56 as a predictive biomarker in the era of novel regimens.

Background Hepatic dysfunction in patients with classical Hodgkin lymphoma (cHL) is of multifactorial aetiology. Prompt evaluation with laboratory tests and imaging methods is sufficient for diagnosis in most cases. Intrahepatic cholestasis and vanishing bile duct syndrome (VBDS) may complicate cHL as rare paraneoplastic phenomena. Liver biopsy provides crucial evidence of cholestasis, and ductopenia, if present, confirms the diagnosis of VBDS. Case report We report on a cHL patient that presented with jaundice and bulky mediastinal disease and unfold the therapeutic dilemmas we confronted. Marked hyperbilirubinemia was successfully reversed with brentuximab vedotin (BV) at a dose of 1.2 mg/kg and the patient was subsequently treated with doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD) at full doses, achieving complete metabolic response. A literature review of intrahepatic cholestasis in cHL is also presented based on currently available data with focus on treatment options and clinicopathologic associations. Conclusion VBDS and intrahepatic cholestasis are rare and potentially fatal complications of cHL. Their prompt recognition and appropriate treatment can dramatically affect cHL patients' outcome. BV, used at a reduced dose as a bridging therapy, should be considered as a high-priority treatment plan in these challenging cases.
