RESUMEN
Cardiotoxicity after allogeneic stem cell transplantation (SCT) is associated with a high rate of mortality and worsening quality of life. The relation between daunorubicin dose and post- allogeneic stem cell transplantation (SCT) cardiotoxicity remains unclear. We retrospectively evaluated 171 patients with acute myeloid leukemia (AML) who underwent their first allogeneic SCT at our institution between 2005 and 2021. High-dose daunorubicin (50 mg/m2/day for 5 days) and cytarabine were usually used as induction therapy for AML. The median cumulative daunorubicin dose was 310 mg/m2 (range, 0-950 mg/m2), and 43 patients received two courses of induction therapy with high-dose daunorubicin (daunorubicin doses of ≥500 mg/m2). Cardiotoxicity developed in 12 patients, and the cumulative incidence at 2 years after SCT was 7.1%. Univariable analysis revealed that female sex, left ventricular ejection fraction (LVEF) of < 60% before SCT, and daunorubicin doses of ≥ 500 mg/m2 were associated with cardiotoxicity. Multivariable analysis showed that a daunorubicin dose of ≥ 500 mg/m2 was an independent risk factor for cardiotoxicity. LVEF decline during the study was observed with an increase in the daunorubicin dose, and only a daunorubicin dose of ≥ 500 mg/m2 was associated with a pre-SCT decreased LVEF. Second induction therapy with high-dose daunorubicin is a risk factor for cardiotoxicity after SCT. This should be taken into consideration when determining reinduction therapies for SCT-eligible patients with relapsed or refractory AML.

Triplet regimens, such as lenalidomide, bortezomib, and dexamethasone (RVd) or thalidomide, bortezomib, and dexamethasone (VTd), are standard induction therapies for transplant-eligible patients with newly diagnosed multiple myeloma (NDMM). The addition of daratumumab to RVd and VTd has been investigated in the GRIFFIN and CASSIOPEIA trials, respectively, resulting in improvement in the rate of minimal residual disease (MRD) negativity. In this study, we conducted a cost-effectiveness analysis with a 10-year time horizon to compare first-line and second-line use of daratumumab for transplant-eligible patients with NDMM. Because long-term follow-up data for these clinical trials are not yet available, we developed a Markov model that uses MRD status to predict progression-free survival. Daratumumab was used either in the first-line setting in combination with RVd or VTd or in the second-line setting with carfilzomib plus dexamethasone (Kd). Quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios were calculated from a Japanese and US payer perspective. In the Japanese analysis, D-RVd showed higher QALYs (5.43 vs 5.18) and lower costs (¥64 479,793 vs ¥71 287 569) compared with RVd, and D-VTd showed higher QALYs (5.67 vs 5.42) and lower costs (¥43 600 310 vs ¥49 471,941) compared with VTd. Similarly, the US analysis demonstrated dominance of a strategy incorporating daratumumab in first-line treatment regimens. Given that overall costs are reduced and outcomes are improved when daratumumab is used as part of a first-line regimen, the economic analysis indicates that addition of daratumumab to first-line RVd and VTd regimens is a dominant strategy compared with reserving its use for the second-line setting.

Tumor lysis syndrome (TLS) is a metabolic disorder caused by massive tumor lysis. Hypouricemic agents are administered to prevent TLS-related hyperuricemia and renal failure. We experienced three cases of urine xanthine crystals during TLS in patients with hematologic malignancies who received prophylactic febuxostat. Yellowish and pinkish deposits were observed in urinary tract catheters and urinary bags. Urine microscopy revealed that the deposits were xanthine crystals. In rapid tumor lysis, inhibition of xanthine oxidase can cause xanthine accumulation and urine xanthine crystallization. During TLS, urine xanthine crystals may be overlooked, so careful observation and management are required to avoid xanthine nephropathy.

The definition of sarcopenia assessed by computed tomography (CT) varies among different reports, and few studies have examined the effect of muscle mass loss on the prognosis of post-hematopoietic cell transplantation (HCT). We retrospectively evaluated 172 patients who underwent an initial allogeneic HCT for acute leukemia at our institution. They were divided into 3 groups according to muscle mass measured at the third lumbar vertebra as assessed by CT. Patients with low muscle mass had a worse performance status, higher comorbidity index and higher disease risk. There was a significant difference in 2-year overall survival between the 3 groups, and worse overall survival (OS) was associated with lower muscle mass (p = 0.005). Muscle mass loss did not affect non-relapse mortality (p = 0.238) but was significantly associated with relapse (p = 0.067). Pre-transplant muscle mass loss may therefore reflect a poor prognosis for the primary disease.

Objective Peripherally inserted central catheters (PICCs) are widely used in patients with hematologic malignancies. However, the risks of PICC-related complications during chemotherapy for acute myeloid leukemia (AML) are not fully understood. Methods We conducted a retrospective review of 128 adult patients with AML who received induction therapy by way of PICC insertion between 2012 and 2019. Results The median duration of PICC insertion was 30 days. The incidence rate of catheter-related bloodstream infection (CRBSI) was 2.4% at 30 days, and women were more likely to suffer from CRBSI than men. Local reactions at the insertion site were observed in 56 patients; however, these events did not predict CRBSI. The incidence rates of catheter-related thrombosis (CRT) were 1.6% at 30 days. Obesity put patients at an increased risk for CRT. Unexpected PICC removal occurred in 59 patients, and women were at a higher risk of catheter removal than men. Conclusion Low PICC-related complication rates, possibly associated with high rates of catheter removal, were observed during intensive chemotherapy for AML. Women and obese patients require careful monitoring of their PICC. Procedures to achieve appropriate PICC removal without increasing the complication rate need to be considered.

We retrospectively examined 57 patients with multiple myeloma who underwent autologous stem cell transplantation (ASCT) at our institution. A receiver-operating characteristic curve (ROC) analysis showed that the reduction rate of quantitative serum monoclonal protein (M-protein) before ASCT and the difference in involved and uninvolved free light chains (dFLC) 30 days after ASCT, respectively, had the greatest predictive value for all patients (area under the curve [AUC] 0.791 and 0.660, respectively). Based on the ROC curve-based cutoff values of tumor burden parameters, progression-free survival (PFS) in the high serum M-protein reduction (≥90 %) group was significantly better than that in the low serum M-protein reduction group (<90 %) (2-year PFS 79.5 % vs. 17.0 %, p < 0.001), but there were no significant differences in PFS between the low (<5.2 mg/L) and high (≥5.2 mg/L) dFLC groups (2-year PFS, 72.0 % vs. 46.0 %; p = 0.149). A multivariate analysis identified the reduction in serum M-protein as an independent predictive factor before ASCT for PFS (hazard ratio [HR] 0.287, p = 0.022) and high dFLC on day 30 after ASCT for PFS (HR 3.902, p = 0.040). These results demonstrate that a good prognosis can be expected with a reduction of serum M-protein before and after ASCT.

High-dose methotrexate (MTX) is widely used for the treatment of hematological malignancies. Despite the application of routine supportive care measures, such as intensive fluid hydration and urine alkalinization, nephrotoxicity is still a problem. The present study aimed to evaluate the risk factors for MTX-induced nephrotoxicity. We retrospectively reviewed 88 patients who received a regimen consisting of high-dose MTX (1000 mg/m2) and cytosine arabinoside between 2006 and 2018. Nephrotoxicity (≥ grade 2) was observed in 11 patients. Nephrotoxicity was observed only in patients with a high MTX concentration. Other than the MTX concentration, the serum uric acid level and urine pH at day 1 were associated with nephrotoxicity. A multivariate analysis revealed that urine pH was an independent risk factor for MTX-induced nephrotoxicity. Urine pH < 7.0 at day 1 was a significant risk factor for nephrotoxicity (odds ratio, 8.05; 95% confidence interval 1.95-33.3) and was also a predictor of delayed MTX elimination at 72 h after injection. Among pre-treatment factors, a low serum calcium level predicted urine pH < 7.0 at day 1. In conclusion, the present study suggests that low urine pH at day 1 is an independent risk factor for MTX-induced nephrotoxicity.

Immune thrombocytopenia (ITP) can coexist with autoimmune thyroid disease. However, the detailed clinical features remain unknown. We retrospectively reviewed 248 patients with newly diagnosed ITP in our institute for whom we had thyroid function data at diagnosis between 2000 and 2019. Of the 248 patients with ITP, 74 patients also had thyroid disease, including 36 with overt thyroid disease (13 Graves' disease and 23 Hashimoto's thyroiditis) and 38 with subclinical thyroid disease (3 hyperthyroidism and 35 hypothyroidism). ITP and thyroid disease were concurrently diagnosed in 54 patients. Female sex and positivity for antinuclear antibodies (ANA) were significantly associated with thyroid diseases. Platelet-associated immunoglobulin G (PAIgG) levels in patients with Graves' disease were higher than those in patients with Hashimoto's thyroiditis. Platelet counts were similar among euthyroid patients and patients with thyroid disease. Thrombopoietin-receptor agonist was administered more frequently in patients with thyroid disease. The cumulative incidences of thrombosis and bleeding and overall survival did not differ between patients with and without thyroid disease. Treatment for thyroid disease in 22 patients improved thrombocytopenia in 21 patients, especially in 4 patients who were not treated for ITP. This study demonstrated that thyroid diseases were commonly found in patients with ITP. Treatment of the underlying thyroid disease may improve thrombocytopenia.

A 68-year-old male patient, who was diagnosed with MGUS (IgG-λ) 11 years ago, was referred to our hospital because of a progressing pancytopenia. He was diagnosed with multiple myeloma (MM) and was hospitalized because of fever and pneumonia. Although empiric antibiotic and antifungal therapies were promptly initiated, his pneumonia worsened. Chest CT images revealed diffuse interstitial pneumonia. Although bortezomib/dexamethasone therapy was initiated as a treatment for MM and pneumonia, he showed little response. His pneumonia worsened and progressed to acute respiratory distress syndrome. Using mPSL (500 mg/day), sivelestat, and MM treatment switching to lenalidomide/dexamethasone (Rd), his respiratory status and CT findings rapidly improved. He received Rd therapy as an outpatient; however, after the completion of six cycles of therapy, his MM progressed, with a recurrence of pneumonia and high fever again. The onset of pneumonia was closely associated with MM progression. His pneumonia improved by treatment with mPSL half-pulse and MM treatment switching to carfilzomib/Rd. In the present study, we report the case of a patient with myeloma, who presented with multiple interstitial pneumonia, resulting in respiratory failure twice in concordance with myeloma progression.
