ABSTRACT
Azacitidine (AZA) has been one of the standard treatments for transplantation-ineligible patients with myelodysplastic syndrome (MDS); however, hematological toxicities frequently cause treatment interruption in the early phase of the therapy. The present study conducted a multicenter retrospective study to investigate the prognostic impacts of various factors, including factors included in the Revised International Prognostic Scoring System (IPSS-R) and severe cytopenia in the early phase of AZA monotherapy in 212 patients with MDS. Severe cytopenia was evaluated after the initiation of therapy by absolute neutrophil counts on the 29th day after AZA (ANC29) initiation, and red cell concentrates (RCC) and platelet concentrate (PC) transfusion units required within 28 days from the start of AZA, designated in the present study as RCC28 and PC28, respectively. The survival period was determined from the 29th day of AZA treatment to death from any cause as the conditional survival period after the first cycle of AZA (CS-AZA1). Multivariate analysis demonstrated that severe thrombocytopenia defined by >30 units of PC28 and very poor risk cytogenetics according to IPSS-R were independent prognostic factors for CS-AZA1. The Kyoto Conditional Survival Scoring System was subsequently developed by incorporating severe thrombocytopenia defined by PC28 and very poor risk cytogenetics, which successfully stratified the risks of the patients in CS-AZA1. In conclusion, extreme PC transfusion dependency during the first cycle of AZA and very poor risk cytogenetics are important prognostic factors in AZA monotherapy for MDS.
ABSTRACT
The use of chimeric antigen receptor T-cell (CAR-T) therapy for hematologic malignancies is rapidly increasing, and appropriately managing adverse events (AEs) is crucial. Cytokine release syndrome (CRS) is a common AE of CAR-T therapy, characterized by systemic symptoms such as fever and respire-circulatory failure. We present two cases with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) accompanied by a rare complication of cervical local CRS as an acute inflammatory reaction at a specific site after CAR-T infusion. Case 1: A 60-year-old gentleman with diffuse large B cell lymphoma (DLBCL) developed grade 1 CRS on day one that required three doses of tocilizumab. Then he developed remarkable cervical edema as local CRS on day five. His local CRS spontaneously improved from day seven without additional therapy. Case 2: A 70-year-old gentleman with DLBCL developed grade 1 CRS on day two that required three doses of tocilizumab. Then he developed remarkable cervical edema and muffled voice as local CRS on day three. He received dexamethasone because of concerns about airway obstruction, and his local CRS improved immediately after dexamethasone administration. Before Tisa-Cel infusion, neither patients had a lymphoma lesion in their necks. To summarize, local CRS may occur at the site without lymphoma involvement after CAR-T therapy. An appropriate diagnosis and careful observation are required to determine the need for additional treatment.
ABSTRACT
The prognostic impact of patient-related factors, including age, nutritional parameters, and inflammation status, in higher-risk myelodysplastic syndromes (HR-MDS) has been largely unexplored. This multicenter retrospective study aimed to establish a real-world practice-based prognostic model for HR-MDS by considering both disease- and patient-related parameters in 233 patients treated with AZA monotherapy at seven institutions. We found that anemia, presence of circulating blasts in peripheral blood, low absolute lymphocyte count, low total cholesterol (T-cho) and albumin serum levels, complex karyotype, and del(7q) or - 7 were poor prognostic factors. Therefore, we developed a new prognostic model called the Kyoto Prognostic Scoring System (KPSS) by incorporating the two variables with the highest C-indexes (complex karyotype and serum T-cho level). The KPSS classified patients into the following three groups: good (0 risk factors), intermediate (1), and poor (2). Median overall survival for these groups was 24.4, 11.3, and 6.9, respectively (p < 0.001). The discriminatory power of the KPSS was higher than that of the traditional International Prognostic Scoring System. In conclusion, we identified several nutritional parameters with prognostic relevance in patients with HR-MDS and generated a prognostic model consisting of complex karyotype and serum T-cho level that enabled excellent risk stratification.

The safety and feasibility of oral fluoroquinolone monotherapy in patients with low-risk febrile neutropenia (FN) were demonstrated in recent studies. Levofloxacin (LVFX) is a commonly prescribed antibiotic; however, evidence for its efficacy against FN is limited. Therefore, in this study, we retrospectively investigated the efficacy of LVFX against low-risk FN in patients with malignant lymphoma at our institution. Treatment success was defined as recovery from fever and neutropenia without alteration of the initial regimen. We recruited 29 patients between January 2013 and December 2018. The median age of the cohort was 64 (range: 21-87) years; 13 (44.8%) were aged over 65 years. In total, 22 patients had diffuse large B-cell lymphoma (DLBCL). Therapy was successful in 24 (82.8%) patients, whereas 5 had treatment failure requiring a change from LVFX to intravenous broad-spectrum antibacterial agents. No deaths related to FN were observed. Two patients required FN-related chemotherapy dose reduction in subsequent cycles. Although this cohort comprised many elderly patients, our study confirmed the efficacy of LVFX in patients with low-risk FN. This may improve the treatment of low-risk FN and malignant lymphoma.

BACKGROUND: Evidence of eribulin therapy for metastatic breast cancer (MBC) in clinical practice is not well documented. METHODS: We retrospectively analyzed the safety and efficacy of eribulin in 29 MBC patients from 2011 to 2016 at Fukuoka University Hospital. RESULTS: The median patient age, number of courses, total dose, and relative dose intensity were as follows: 65 years, five courses, 8.6 mg/m2 , and 75%, respectively. One patient achieved a complete response, (CR) six a partial response (PR), eight stable disease (SD) and 14 patients exhibited progressive disease. The objective response rate (ORR: CR + PR) was 24.1%, and the clinical benefit rate (CBR: CR + PR + SD) was 51.7%. The median progression-free survival was 90 days (95% confidence interval [CI] 67-126) and median overall survival was 264 days (95% CI 198-357). In patients who previously received 2-4 regimens, the ORR was 28.5% and the CBR was 57.1%. In patients who received 5-12 regimens, the ORR was 20% and the CBR was 45%. Chemotherapy was administered to 20 patients (69%) after eribulin administration, and the median overall survival rate of cases that achieved greater than a PR was 1088 days. The most frequent treatment-related grade 3/4 adverse events were neutropenia (55.2%), and febrile neutropenia (20.1%). Grade 3 peripheral neuropathy occurred in 13.8% of patients, but was not exacerbated even if present before treatment. CONCLUSION: Eribulin is effective for MBC patients who have received multiple chemotherapies. Neutropenia and febrile neutropenia may develop after heavy prior therapy.
