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 FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
