    Title translation Biopsia de médula ósea en el linfoma de Hodgkin. Comparación con la PET-TC en 65 pacientes.
    Abstract Background and objectives: To compare bone marrow biopsy (BMB) and PET/CT in detecting bone marrow involvement in Hodgkin's lymphoma MATERIAL AND METHODS: Retrospective analysis of 65 patients with both tests in the initial staging or in relapse with special attention to the PET/CT uptake pattern.
    Results: In 3 patients (4.6%), the BMB showed bone marrow involvement with the PET/CT being positive in them all: 2 with diffuse+multifocal pattern and one diffuse only. In 11 additional patients (total 14/65, 21%), bone marrow involvement was diagnosed by PET/CT because bone marrow uptake was above hepatic one. The pattern was focal only in 2 cases, multifocal in 5, diffuse in 3 and diffuse+multifocal in one. In these last 4 cases the BMB showed an unspecific myelopathy.
    Conclusions: PET/CT detects all cases with BMB affected and many that escape to biopsy, however when the uptake pattern is diffuse it could be by involvement or reactive hyperplasia and in those cases the BMB should be done.

    Abstract Objective: To describe the reasons for and result of thrombopoietin receptor agonists (TPO-RA) switching in adult immune thrombocytopenia (ITP) patients of 4 Spanish centres.
    Methods: We retrospectively analysed all patients who received sequential treatment with both TPO-RA between 2010 and 2015 recording clinical and biological parameters.
    Results: Twenty-six patients were included; 17 received first romiplostim and 9 received first eltrombopag. Reasons for switching were inefficacy (n = 10), patient preference (n = 8), side effects (n = 5) and excessive platelet count fluctuation (n = 3). When the switch was due to inefficacy, 100% of patients who received romiplostim first and 66% who received eltrombopag first responded to the second drug. It is significant that none of the patients who received romiplostim first reached the maximum recommended dose before switching. When the change was due to patient preference or because of side effects, 100% of the patients responded to both TPO-RA. Three patients changed from romiplostim to eltrombopag due to platelet count fluctuation; one did not respond and the fluctuation persisted in the remaining 2 patients. We also found 4 sustained remissions after administering the second TPO-RA, 2 of these with inefficacy of the first drug.
    Conclusion: TPO-RA switching is a feasible strategy in different scenarios with high probability of success.

    Abstract Background: Ruxolitinib is approved for patients with polycythemia vera (PV) who are resistant/intolerant to hydroxyurea, but its impact on preventing thrombosis or disease-progression is unknown.
    Methods: A retrospective, real-world analysis was performed on the outcomes of 377 patients with resistance/intolerance to hydroxyurea from the Spanish Registry of Polycythemia Vera according to subsequent treatment with ruxolitinib (n = 105) or the best available therapy (BAT; n = 272). Survival probabilities and rates of thrombosis, hemorrhage, acute myeloid leukemia, myelofibrosis, and second primary cancers were calculated according to treatment. To minimize biases in treatment allocation, all results were adjusted by a propensity score for receiving ruxolitinib or BAT.
    Results: Patients receiving ruxolitinib had a significantly lower rate of arterial thrombosis than those on BAT (0.4% vs 2.3% per year; P = .03), and this persisted as a trend after adjustment for the propensity to have received the drug (incidence rate ratio, 0.18; 95% confidence interval, 0.02-1.3; P = .09). There were no significant differences in the rates of venous thrombosis (0.8% and 1.1% for ruxolitinib and BAT, respectively; P = .7) and major bleeding (0.8% and 0.9%, respectively; P = .9). Ruxolitinib exposure was not associated with a higher rate of second primary cancers, including all types of neoplasia, noncutaneous cancers, and nonmelanoma skin cancers. After a median follow-up of 3.5 years, there were no differences in survival or progression to acute leukemia or myelofibrosis between the 2 groups.
    Conclusions: The results suggest that ruxolitinib treatment for PV patients with resistance/intolerance to hydroxyurea may reduce the incidence of arterial thrombosis.
    Lay summary: Ruxolitinib is better than other available therapies in achieving hematocrit control and symptom relief in patients with polycythemia vera who are resistant/intolerant to hydroxyurea, but we still do not know whether ruxolitinib provides an additional benefit in preventing thrombosis or disease progression. We retrospectively studied the outcomes of 377 patients with resistance/intolerance to hydroxyurea from the Spanish Registry of Polycythemia Vera according to whether they subsequently received ruxolitinib (n = 105) or the best available therapy (n = 272). Our findings suggest that ruxolitinib could reduce the incidence of arterial thrombosis, but a disease-modifying effect could not be demonstrated for ruxolitinib in this patient population.

    Abstract Although hydroxyurea is considered the first-line cytoreductive therapy in high-risk patients with polycythemia vera or essential thrombocythemia, approximately 20-25% of patients develop resistance or intolerance and they need an alternative therapy. Anagrelide is the treatment of choice in patients with essential thrombocythemia intolerant or with resistance to hydroxyurea. Anagrelide is usually well tolerated. Although there is concern about the increased risk of cardiac side effects, in most cases these are mild, and easily manageable. In this paper, the available evidence about the management of patients with myeloproliferative neoplasms, with a special focus on the side effects of drug therapies is reviewed.

    Abstract Hematological control, incidence of complications, and need for cytoreduction were studied in 453 patients with low-risk polycythemia vera (PV) treated with phlebotomies alone. Median hematocrit value decreased from 54% at diagnosis to 45% at 12 months, and adequate hematocrit control over time (< 45%) was observed in 36%, 44%, and 32% of the patients at 6, 12, and 24 months, respectively. More than 5 phlebotomies per year in the maintenance phase were required in 19% of patients. Worsening thrombocytosis, age > 60 years, and microvascular symptoms constituted the main indications for starting cytoreduction. Median duration without initiating cytoreduction was significantly longer in patients younger than 50 years (< 0.0001). The incidence rate of thrombosis under phlebotomies alone was 0.8% per year and the estimated probability of thrombosis at 10 years was 8.5%. The probability of arterial thrombosis was significantly higher in patients with arterial hypertension whereas there was a trend to higher risk of venous thrombosis in cases with high JAK2V617F allele burden. Rates of major bleeding and second primary neoplasm were low. With a median follow-up of 9 years, survival probability at 10 years was 97%, whereas the probability of myelofibrosis at 10 and 20 years was 7% and 20%, respectively. Progression to acute myeloid leukemia was documented in 3 cases (1%). Current management of low-risk PV patients is associated with low rate of thrombosis and long survival. New treatment strategies are needed for improving hematological control and, in the long term, reducing progression to myelofibrosis.
