ABSTRACT
Central nervous system (CNS) involvement is a rare and aggressive complication of multiple myeloma (MM). We identified 54/4352 MM patients (1.2%), who developed CNS-MM between 2000 and 2022. A matched-control group of MM patients without CNS-MM was used for comparisons. Median age was 63 years. Median time to CNS-MM was 28 months; 6/54 experienced CNS-MM at MM diagnosis. Abnormal lactate dehydrogenase (LDH), high-risk cytogenetics, and extramedullary involvement (EMI), that is, soft tissue plasmacytomas and/or plasma cell leukemia (PCL), were more frequent in CNS-MM versus controls (p < .05); 13/54 had PCL at CNS-MM. The majority had leptomeningeal infiltration (LMI) (66%); 26% had CNS-MM without systemic myeloma; EMI was the strongest predictor for CNS-MM (OR: 6.3). Median overall survival (OS) of CNS-MM patients versus controls was 43 months (95% CI: 32-54) versus 60 months (95% CI: 38-82) (p < .001); treatment of CNS-MM included mainly bortezomib/thalidomide/chemotherapy whereas 20% received novel drugs/immunotherapy combinations; 28 patients underwent cerebrospinal fluid infusions; EMI was the strongest negative predictor for post CNS-MM OS (p = .005; HR: 2.9). Treatment after 2016 predicted significantly for OS (p = .002; HR: 0.27). Median post CNS-MM OS was 4 months (95% CI: 2.6-5.4); in patients treated after 2016 median OS was 12 months. In conclusion, we have demonstrated in this large real-world series that survival of CNS-MM remains poor; however, there is a positive impact of treatment after 2016, related to the efficacy of modern anti-myeloma therapy; EMI significantly increases the probability to develop CNS-MM and the risk of post CNS-MM death, indicating a potential need for CNS prophylaxis for those patients.
ABSTRACT
INTRODUCTION: Recommendations about proper anticoagulation in obese patients, body mass index (BMI) > 30 kg/m2, are not yet clearly defined. Obese patients were included in randomized controlled trials comparing new anticoagulants (NOACs) with warfarin in patients with atrial fibrillation or thromboembolism. METHODS: We performed a medline search entering proper criteria and finally 6 post-hoc analysis of RCTs, reporting outcome according to BMI, were included in this meta-analysis. Two major outcomes were considered end points in our meta-analysis; thrombosis, including ischemic cerebral events (transient or not) and venous thrombosis (DVD) /pulmonary embolism (PE) and bleeding, including major bleeding and clinically relevant non-major bleeding. RESULTS: In the NOACs treated group, thrombosis occurred less frequently in obese vs non-obese patients; RR and 95 % CI 0,75 (0,58-0,97), p = 0,03, while low heterogeneity was observed (I2= 40 %). In the warfarin treated subgroup there was statistically significant difference with less thrombotic events occurring in the obese vs non-obese patients; RR and (95 % CI) 0,80 (0,66-0,98), p = 0,03, and heterogeneity was low (I2 = 24 %). This protective effect called the obesity paradox is limited to obese patients anticoagulated for non-valvular atrial fibrillation (NVAF); RR (95 % CI) was 0,70 (0,58-0,85) p = 0,03 and I2 = 24 %. Bleeding events were similar under both NOACs and warfarin in obese vs non-obese analysis. CONCLUSIONS: Obese patients anticoagulated for NVAF with either standard dose of xabans or INR guided warfarin are more efficiently protected against thrombosis compared to non-obese patients.

RCHOP is the standard of care for patients with diffuse large b-cell lymphoma (DLBCL) but failures occur in approximately 40% of them. We performed a meta-analysis of 21 randomized controlled trials (RCTs) comparing experimental regimens with RCHOP. We searched the database of PubMed with proper criteria, and data of efficacy (Progression Free Survival-PFS) in the ITT population were extracted and analyzed. Cross comparisons of RCTs were performed by using the CINEMA software. Odds ratio (OR) and 95% confidence intervals (95%, CI) are reported. The literature search yielded 21 RCTs including 5785 patients in the RCHOP arm and 5648 patients in the experimental arm. Odds ratio (OR) for PFS in the total cohort was OR (95%, CI): 0.87 (0.76-0.99), p=0.02. Among different strategies to improve RCHOP, addition of a novel agent on RCHOP improved PFS. In total 1740 patients in the RCHOP arm were compared with 1755 in the RCHOP plus a novel agent arm, and the OR (95% CI) for PFS was 0.84 (0.71-0.97), p=0.02. Indirect comparisons of nine studies adding a novel agent on RCHOP does not give prominence to any agent. Subgroup analysis according to cell of origin was performed for non-GC DLBCL patients. In this subgroup, 1546 patients treated with RCHOP were compared with 1538 patients treated with experimental regimens. The OR (95% CI) for PFS was 0.86 (0.73-1.02), p=0.34. Overall survival data extracted from 18 studies showed no superiority of experimental regimens over RCHOP. Efficacy of RCHOP backbone is marginally improved when adding a novel anti-lymphoma agent.

Optimal anticoagulation in patients with end-stage renal disease ESRD is a matter of debate since these patients are not included in randomized controlled trials (RCTs). Evolving data are in favor of apixaban compared to warfarin. METHODS: We extracted data from 2 RCTs, 5 retrospective cohort studies and 3 large data-based studies. Both dosing regimens of apixaban, standard or reduced, were accepted. In most studies characteristics of patients were balanced between arms. Patients with either atrial fibrillation (AF) or venous thromboembolism (VTE) were included. Quality of studies was graded as high and the funnel plot did not detect any publication bias. In total we analyzed the outcome of 6693 ESRD patients treated with apixaban and 19,836 treated with warfarin. Our analysis was performed by using the random effects model. We report our data as Risk Ratio (RR) and associated 95 % confidence interval values (95 %, CI). RESULTS: The RR (95 % CI) of major bleeding was 0.69 (0.57-0.84) p = 0.0002 in favor of apixaban vs warfarin with heterogeneity to be statistically significant I2 63% p = 0.004. Meta-regression analysis with year of publication as moderator shows in bubble plotting that studies published earlier than 2018 were plotted as outliers. The RR (95 % CI) of clinically relevant non-major bleeding (CRNMB) was 0.74 (0.64-0.87) p = 0.0002 favoring again apixaban. Standard apixaban dose over reduced dose is less hemorrhagic compared to warfarin. Overall, in our study the risk of thrombosis in both arms was statistically non-different. CONCLUSIONS: In our study we observed less hemorrhagic events with apixaban in ESRD patients compared to warfarin.

OBJECTIVES: The role of hereditary thrombophilia in reproductive failure (RF) is strongly debatable. In this retrospective single-center study, we analyzed pregnancy outcome in 175 women screened for thrombophilia after at least one event of RF. RESULTS: The prevalence of thrombophilia in our cohort was 33.4%. Pregnancy survival curves were not different according to severity (log-rank, p = 0.302) or type of thrombophilia (log-rank, p = 0.532). In total, 81.7% of 175 subsequent pregnancies were proceeded with LMWH. Concomitant use of ASA was prescribed in 75 pregnancies according to physician choice. The primary endpoint was live birth rate (LBR) that succeeded in 152/175 next pregnancies (86.8%) and late obstetric complications (LOBC) which occurred in 17/175 next pregnancies (9.8%). In logistic regression analysis, neither the severity nor the type of thrombophilia was important for any pregnancy outcome (LBR or LOBC). Considering therapeutic interventions, the use of LMWH ± ASA was not related to LBR or LOBC. The only factor inversely related to LBR was age above the cutoff value of 35.5 years (p = 0.049). CONCLUSIONS: Incidence of thrombophilia is increased among women with RF, but the severity or type of thrombophilia is not related to pregnancy outcome.

INTRODUCTION: Socioeconomic status (SES) has been shown to be a prognostic factor for overall survival in a variety of hematologic malignancies, especially for patients who require continuous care such as those with multiple myeloma (MM). PATIENTS AND METHODS: We retrospectively collected data from 223 patients with symptomatic MM diagnosed and treated in our department from January 2005 to December 2019. The modified Kuppuswamy scale, slightly modified, was used for the SES assessment. The Kaplan-Meier estimator of survival and Cox regression analysis were used. RESULTS: In our cohort of 223 patients with MM, low SES was an independent poor prognostic factor for overall survival (OS), in addition to higher International Staging System stage and high-risk cytogenetics (hazard ratio for low SES on Cox regression analysis, 2.092; 95% confidence interval [CI], 1.36-3.2; log-rank P = .000). Patients with low SES had inferior survival compared with the whole patient cohort (median OS: low SES, 28 months; 95% CI, 18-37.9; high SES, 68 months; 95% CI, 55.6-80.4; log-rank P = .000). The low SES effect on OS was more evident for the elderly patients who were not transplant eligible and in those with a diagnosis of MM International Staging System stage I. The effect of low SES on OS was attenuated by time, and ethnic origin had no effect on OS. CONCLUSIONS: The results of the present study have shown that low SES is an independent poor prognostic factor for survival of patients with MM.
