Description: INTRODUCTION Anemia is the most frequent cytopenia in lower-risk MDS. Erythropoietic-stimulating agents (ESAs) are commonly used in these patients. The use of ÒclassicalÓ parameters (EPO and ferritin levels) and the revised IPSS (IPSS-R) has been proposed1 (SantiniÕs score) to predict response to ESAs and overall survival (OS) among patients with lower risk MDS by IPSS and a favorable Nordic group score2. OBJECTIVES The main objective of the study was to evaluate overall response rate (ORR) to ESAs and OS according to the proposed SantiniÕs score in an independent and large cohort of anemic lower risk MDS patients receiving treatment with ESAs. METHODS Data from 530 anemic patients with low/int1 risk IPSS de novo MDS (according to FAB and WHO criteria) and sufficient follow-up data available were recorded in Spresas3 (SPanish Registry of Erythropoietic Stimulating Agents Study from GESMD). Two hundred and twenty six patients (42.6% of the patients) were selected according to specific criteria regarding the published SantiniÕs score1: Hb level 350 ng/mL(=1) and IPSS-R very low=0, low=1, intermediate=2 and high=3) yielded a score ranging from 0 to 5. ESAs response rate and overall survival were analysed according to these score. Response to treatment was evaluated according to IWG 2006 response criteria and a multivariate logistic regression analysis was used to identify independent predictors of erythroid response (ER). OS were defined as the time between diagnosis and the corresponding event or last follow up (Feb 2015) and were analyzed using univariable and multivariable Cox proportional hazards regression methods. RESULTS Median age was 77 years (interquartile range [IQR] 25%-75%: 71-83 y), median Hb level at start of treatment was 10 g/dL (IQR25-75: 9-10), median EPO level was 90 (IQR25-75: 27,25-108) and median ferritin level was 338,5 (IQR25-75: 146,5-568,75). Among 139 patients with this data available, 85 patients (61,1%) were RBC transfusion dependent before ESAs treatment. Median time from diagnosis to ESAs treatment was 82 (IQR25-75: 27-353) days. According to the IPSS, 68.6% (N=155) and 31.4% (N=71) were in low and Int-1 risk groups, respectively. Regarding IPSS-R, 23% (N=52), 66.8% (N=151), 9.7% (N=22) and 0.4% (N=1) were in very low, low, intermediate and high risk, respectively. ORR to ESA treatment was 71.2% (N=161), with a median duration of response of 2.06 years. Prognosis factors of ER showed a trend toward to a higher ER among patients in the lower IPSS-R (P〉0.05), low IPSS (p=0.039) and lower EPO levels (p

Description: Introduction: Diffuse large B-cell lymphoma (DLBCL) is one of the most common malignant neoplasms in elderly patients, potentially curable when optimum treatment is administered. The combination of rituximab with CHOP chemotherapy (R-CHOP) is considered standard for these patients, but randomized studies published to date are limited to the range of age from 60 to 80 years, so that in patients over this age treatment election is not so clear, usually opting for palliative treatment or a "full" treatment at a reduced dose. This retrospective study is primarily aimed to analyze the influence of the type of treatment and comorbidity scales in overall survival (OS) of a large series of patients 〉80 years with aggressive B-cell lymphoma. Methods: Eligible patients were aged ≥ 80 years, diagnosed of DLBCL, follicular lymphoma grade 3B or transformed lymphoma. The main patient characteristics were obtained retrospectively from the medical records, including a complete geriatric assessment (CGA, "comprehensive geriatric assessment") and the Charlson comorbidity index. The Ethics Committee of the University Hospital of Salamanca approved the study. Results: 288 patients from 19 GELTAMO hospitals were registered in the study, of which 234 (60% women) were evaluable and have been included in this preliminary analysis. The median age was 84 years (80-94) and the vast majority (94%) were DLBCL. According to the Charlson index, 65% of patients were low-intermediate risk, and according to CGA, 63% of patients were considered "fit". A higher proportion (60% v 44%, p = 0.03) of patients with low or intermediate comorbidity index were treated with a curative intent (CHOP +/- rituximab), as compared with patients with high or very high index. With a median follow up of 41 (range 9-142) months, the median OS was 11.5 months (33% estimated at 3 years). The median OS for patients treated with R-CHOP-like (N=96) was 35.3 months, significantly better (p

Description: Introduction The prognosis of patients with recurrent or refractory acute myeloid leukemia (AML-RR) is very poor, especially if they are not candidates for allogeneic transplantation (allo-SCT) after a second complete response (CR). Venetoclax, a potent and selective inhibitor of the antiapoptotic protein BCL-2, was approved by the FDA in combination with hypomethylating agents (HMAs) or low-dose cytarabine (LDAC) in patients with newly diagnosed AML of age ≥ 75 years, or who have comorbidities that preclude the use of intensive chemotherapy. However, the evidence in AML-RR patients is still scarce. For this reason, the objective of our study is to retrospectively analyze the efficacy of the off-label use of venetoclax in patients with AML-RR. Methods We conducted a retrospective, multicenter, observational study of a cohort of patients with AML-RR who were treated with venetoclax in the hospitals of the PETHEMA group. We evaluated efficacy, CR/CRi rate and overall survival (OS). We performed a descriptive analysis. Overall survival (OS) was calculated using the Kaplan-Meier method. Results A total of 41 patients were included, 25 men and 16 women, with a median age of 68 years (25 - 82 years) and an ECOG ≥ 2 at the beginning of the venetoclax treatment in 52% of the cases. Seventy-five percent of patients had AML with myelodysplasia-related changes. 25 patients (61%) were at high risk according to the European Leukemia Net 2017. Sixty-six percent of patients received ≥2 previous lines (range, 1-4), 29 patients (71%) received intensive first line chemotherapy, 10 (25%) received a previous transplant and 18 (44%) received previous treatment with HMA. Venetoclax median treatment duration was 40 days, and it was administered in 54% with azacitidine, 34% with decitabine and 12% with LDAC. In all, 11% of patients achieved CR/CRi. Only 10% of patients received subsequent salvage treatment. With a median follow-up time of 166 days (range, 21 - 311), 65% of the patients died. The median OS from diagnosis was 15 months (1 - 67 months) and the median from venetoclax initiation was 78 days (2 - 311 days). Those patients who achieved CR/CRi had higher OS (median not reached vs. 78 days, p= 0.048). Regarding toxicity, it was the expected in these patients. Twenty-eight percent of the patients required discontinuation of treatment due to toxicity. Sixty percent of the patients were admitted at some time during treatment with venetoclax, mainly because of infections (53%), 12% because of bleeding and other causes in 15%. Conclusions Our real-life series depicts a marginal probability of CR/CRi and poor OS after venetoclax-based salvage. Patients treated with this regimen had very poor-risk features, and were heavily pre-treated, which could explain in part the observed poor outcomes. Although follow-up is still short, the small proportion of responders did not reach the median overall survival. Further studies will help to identify those patients potentially benefiting from venetoclax-based salvage regimens.
