    The International Prognostic Score (IPS) is the most commonly used risk stratification tool for patients with advanced Hodgkin lymphoma (HL). It incorporates seven clinical parameters independently associated with a poorer outcome: male sex, age, stage IV, hemoglobin level, white blood cell and lymphocyte counts, and albumin level. Since the development of the IPS, there have been significant advances in therapy and supportive care. Recent studies suggest that the IPS is less discriminating due to improved outcomes with ABVD therapy. The aim of the present study was to asses if classic prognostic factors maintain their prognostic meaning at the time of response-adapted treatment based on interim PET scans. We evaluated the prognostic significance of IPS in the 520 advanced stage HL patients enrolled in the PET-guided, HD0801 trial in which PET2-positive patients underwent a more intense treatment with an early stem-cell transplantation after 2 cycles of ABVD. We observed that in these patients, the IPS completely loses its prognostic value together with all the single parameters that contribute to the IPS. Furthermore, neutrophils, monocytes, lymphocytes, and the ratio among them also no longer had any predictive value. We believe that the substantial improvement in survival outcomes in PET2-positive patients treated with early autologous transplantation could explain the complete disappearance of the residual prognostic significance of the IPS

    Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare entity whose neoplastic cells retain a B-cell phenotype with expression of CD20. Radiotherapy is recommended for favorable stage IA disease while for other stages guidelines suggest therapeutic strategies similar to those used for classic HL. The role of rituximab, although quite widespread, is not completely elucidated. We retrospectively analyzed baseline characteristics of 308 consecutive patients with NLPHL diagnosed in 19 Italian centers from 2000 to 2018. With a median follow-up of 8.4 years (interquartile range: 4.5-12.4) for treated patients, median overall survival (OS) was not reached and estimated 5-year OS was 97.8% and 5-year progression-free survival (PFS) was 84.5%. Five-year cumulative incidence of histological transformation was 1.4%, 95% confidence interval (CI), 0.5%-3.8%. After adjusting for lymphocyte count, splenic involvement, bulky disease and B symptoms (fever, drenching night sweats, unintentional loss >10% of body weight within the preceding 6 months), patients with stage II or more showed superior PFS with immunochemotherapy in comparison to chemotherapy alone (hazard ratio = 0.4, 95% CI, 0.2-0.8; P = 0.015). Our data suggest an advantage of the use of rituximab combined with chemotherapy ± radiotherapy in the treatment of stage II-III-IV NLPHL

    Italian real life experience with brentuximab vedotin : results of a large observational study on 234 relapsed/refractory Hodgkin's lymphoma

    A large Italian multicenter observational retrospective study was conducted on the use of brentuximab vedotin (BV) for patients with relapsed Hodgkin's lymphoma (HL) to check if clinical trial results are confirmed even in a real life context. 234 CD30+ HL patients were enrolled. Best response was observed after a median of 4 cycles in 140 patients (59.8%): 74 (31.6%) patients obtained a complete response (CR) and 66 (28.2%) achieved a partial response (PR); overall response rate at the end of the treatment was 48.3% (62 CR and 51 PR). The best response rate was higher in the elderly subset: 14 (50%) CR and 5 (17.8%) PR. Disease free survival was 26.3% at 3 years and progression free survival 31.9% at 4.5 years. Duration of response did not differ for who achieved at least PR and then either did or did not undergo consolidative transplant. Overall, the treatment was well tolerated and no death has been linked to BV-induced toxicity.Our report confirms activity in elderly patients, duration of response unrelated to the consolidation with transplant procedure, the relevance of the CR status at first restaging, and the role of BV as a bridge to transplant for chemorefractory patients

    Context. Temperature is a crucial parameter in circumstellar disk evolution and planet formation because it governs the resistance of the gas to gravitational instability and sets the chemical composition of the planet-forming material. Aims. We set out to determine the gas temperature of the young disk-like structure around the Class 0 protostar IRAS 16293-2422A. Methods. We used Atacama Large Millimeter/submillimeter Array (ALMA) observations of multiple H2CS J = 7 - 6 and J = 10 - 9 lines from the Protostellar Interferometric Line Survey (PILS) to create a temperature map for the inner similar to 200 AU of the disk-like structure. This molecule is a particularly useful temperature probe because transitions between energy levels with different K-a quantum numbers operate only through collisions. Results. Based on the H2CS line ratios, the temperature is between similar to 100-175 K in the inner similar to 150 AU, and drops to similar to 75 K at similar to 200 AU. At the current resolution (0.5 \u27\u27similar to 70 AU), no jump is seen in the temperature at the disk-envelope interface. Conclusions. The temperature structure derived from H2CS is consistent with envelope temperature profiles that constrain the temperature from 1000 AU scales down to similar to 100 AU, but does not follow the temperature rise seen in these profiles at smaller radii. Higher angular resolution observations of optically thin temperature tracers are needed to establish whether cooling by gas-phase water, the presence of a putative disk, or the dust optical depth influences the gas temperature at less than or similar to 100 AU scales. The temperature at 100 AU is higher in IRAS 16293A than in the embedded Class 0/I disk L1527, consistent with the higher luminosity of the former

    Background and Objectives: In adult acute lymphoblastic leukaemia (ALL), unlike in childhood ALL, the percentage of long-term remitters and survivors has not improved significantly over the last decades. In the present analysis, we describe a series of adult ALL patients consecutively treated with the same regimen in order to analyse prognostic factors and treatment outcome as well as to define new risk-oriented strategies. Design and Methods: From 1990 to 1998, 102 newly diagnosed ALL patients were referred to our division, 83 of them were eligible for the present study. Median age was 31 years (range 13-76); 77.1% had B-lineage ALL and 22.9% T-lineage ALL; 36.1% showed associated myeloid markers. All patients received an induction phase treatment, consisting of a 4-week cycle with vincristine, daunorubicin, L-asparaginase and desametasone; the consolidation phase included cyclophosphamide, cytarabine, 6-mercaptopurine and central nervous system (CNS) prophylaxis, followed by three of months maintenance (methotrexate + 6-mercaptopurine), re-induction (4-week cycle with vincristine, adriamicin, desametasone), and 2-year maintenance with methotrexate + 6-mercaptopurine. Results: Complete remission (CR) was achieved in 66 patients (79.5%); 20.5% of patients were resistant. The relapse rate was 60.2%. There were 10 CNS relapses (accounting for 12% of all patients, 15% of all CRs and 20% of all relapses). One patient had an ovarian and 2 had a breast relapse. Eleven patients remained in first continuous CR after chemotherapy. Median overall survival (OS) and disease-free survival (DFS) were 1.8 and 1.0 years, respectively, with a median follow-up of 5.6 years (range 0.3-12.1). Initial white blood cell count 6430 7 109/l, age <35 years, and time to complete remission 6440 days were the most significant prognostic factors for OS (p < 0.05). These three characteristics defined a group of patients with a better prognosis (5-year OS: 58%). They represented, however, only 18% in this series of adult patients. Interpretation and Conclusions: In our cohort, we were able to define a small subgroup of adult ALL patients with a better outcome. However, the majority of patients is at a high risk of failure when treated with standard protocols. There is a need for new, more active regimens for these patients. Copyrigh

    Gene expression in the Andes; relevance to neurology at sea level.

    Chronic mountain sickness (CMS), a maladaptation syndrome to chronic hypoxia, occurs in the Andes. Gene expression differences in Andeans could explain adaptation and maladaptation to hypoxia, both of which are relevant to neurology at sea level.Expression of genes responsive to cellular oxygen concentration, hypoxia-inducible factor-1alpha (HIF-1alpha), three splicing variants of vascular endothelial growth factor (VEGF) and von Hippel-Lindau protein (pVHL) was measured by reverse transcription polymerase chain reaction (RT-PCR) in 12 Cerro de Pasco (CP) (altitude 4338 m) natives and 15 CMS patients in CP. Thirteen high altitude natives living in Lima and five Lima natives were sea level controls. A CMS score (CMS-sc) was assigned clinically. Expression was related to the clinical assessment.High expression of HIF-1alpha and VEGF-121 was found in CMS (P<0.001). Samples from CP had higher expression than those from Lima (P<0.001). Expression of HIF-1alpha and VEGF-121 was related to age (P<0.001); adjusting for age did not abolish the group effect. Higher CMS-sc was related to expression independent of age (P<0.001). VEGF-165 and -189 were expressed only in CMS. Birth altitude had no effect on gene expression. pVHL was not quantifiable.HIF-1alpha and VEGF-121 participate in adaptation to hypoxia. The high levels may explain blood vessel proliferation in Andeans and hold lessons for patients at sea level. VEGF-165 expression suggests that it contributes to preservation of neuronal function in human chronic hypoxia. VHL mutations may mark those destined to develop neural crest tumors which are common in the Andes

    Cerebral vasoreactivity in Andeans and headache at sea level.

    Headache is common in Cerro de Pasco (CP), Peru (altitude 4338 m) and was present in all patients with chronic mountain sickness (CMS) in CP reported here. Forty-seven percent of inhabitants report headache. Twenty-four percent of men have migraine with aura, with an average of 65 attacks a year. We assessed vasoreactivity of the cerebral vessels to CO2 by rebreathing and to NO by the administration of isosorbite dinitrate (IDN), a nitric oxide (NO) donor, using transcranial Doppler ultrasound in the middle cerebral artery (MCA) in natives of CP, some of whom suffered from CMS. We repeated the measurements in Lima (altitude 150 m) in the same subjects within 24 h of arrival. Vasodilatation in the middle cerebral artery supply territory in response to CO2 and NO, both physiologic vasodilators, is defective in Andean natives at altitude and in the same subjects at sea level. Incapacitating migraine can occur with impaired cerebral vasoreactivity to physiologic vasodilators. We propose that susceptibility to migraine might depend in part on gene expression with consequent alterations of endothelial function
