Low-risk HPLLs/ABC score patients with splenic marginal zone lymphoma can be safely managed without treatment: Results from a prospective Spanish study.

The aims of our study were to analyse compliance with the 2014 GELTAMO SMZL Guidelines, in patients with splenic marginal zone lymphoma (SMZL), and to evaluate the outcome according to the HPLLs/ABC-adapted therapeutic strategy. Observational prospective multicenter study of 181 SMZL patients diagnosed between 2014 and 2020. Lymphoma-specific survival (LSS), composite event-free survival (CEFS) and response rates were assessed. 57% of the 168 patients included in the analysis followed the Guidelines. The overall response rate was higher in the rituximab chemotherapy and in the rituximab arms compared with the splenectomy arm (p < 0.001). The 5-year overall survival was 77% and the 5-year LSS of 93%. There were no differences in the 5-year LSS according to the treatment received (p = 0.68). The 5-year CEFS in the overall series was 45%, and there were significant differences between scores A and B (p = 0.036). There were no significant differences when comparing LSS and progression-free survival in patients treated with rituximab or rituximab chemotherapy at diagnosis or after observation. Our data support HPLLs/ABC score as a practical tool for the management of SMZL, observation as the best approach for patients in group A and rituximab as the best treatment for group B.

Evolution of patients with chronic hepatitis C infection with advanced fibrosis or cirrhosis cured with direct-acting antivirals. Long-term follow-up. / Evolución de los pacientes con infección crónica por hepatitis C con fibrosis avanzada o cirrosis curados con antivirales de acción directa. Seguimiento a largo plazo.

AIMS: To analyze laboratory parameters, clinical and fibrosis evolution in F3-F4 patients cured with direct-acting antivirals (DAA). PATIENTS AND METHODS: Unicenteric, observational and prospective study. All F3-F4 hepatitis C patients cured with DAA from 01/11/2014 to 31/08/2019 were included. A basal visit (BV) was performed and at 12 weeks (12w), 1, 2, 3 and 4 years after treatment. Demographic and laboratory variables, fibrosis measured by non-invasive tests, indirect markers of portal hypertension, the presence of esophageal varices, cirrhosis decompensation and hepatoceullar carcinoma were collected. RESULTS: 169 patients were treated: 123 (72.8%) men, age 57.5±12 years; 117 (69.2%) with cirrhosis, 99 (84.6%) ChildA. 96,4% achieved SVR. The study was conducted for a median follow-up of 46.14 (2.89-62.55) months. It was observed a significant increase in platelets [155×103/µL (BV); 163×103/µL (12w)], cholesterol [158mg/dL (BV); 179mg/dL (12w)] and albumin [4.16g/dL (BV); 4.34g/dL (12w)] and a significant decrease in ALT [82UI/L (BV); 23UI/L (12w], AST [69UI/L (BV); 26UI/L (12w)], GGT [118UI/L (BV); 48UI/L (12w)] and bilirrubin [0.9mg/dL (BV); 0.7mg/dL (12w)]. Fibrosis also improved early in follow-up, both by serological methods and Fibroscan [19.9kPa (BV); 14.8kPa (12w; P<.05]. 8.1% of compensated cirrhosis patients had some decompensation. 4.5% developed esophageal varices. Nine patients (5.52%) had de novo hepatocellular carcinoma; 6 (3.68%) had hepatoceullar carcinoma in BV and 40% had a recurrence. During follow-up mortality was 9.2%. CONCLUSIONS: There is an improvement in laboratory parameters and fibrosis measured by non-invasive methods in F3-F4 patients cured with DAA. However, the risk of decompensation and the incidence/recurrence of hepatocellular carcinoma still remain, so there is a need to follow these patients.

Hepatitis B and C screening in hospitalized patients with SARS-CoV-2 infection. / Cribado de infección por virus de la hepatitis B y C en pacientes hospitalizados con infección por SARS-CoV-2.

AIMS: To evaluate the results of a hepatitis B and C screening program in hospitalized COVID-19 patients. METHOD: Transversal prospective study conducted in two Spanish hospitals. Patients admitted from March 1st to December 31st 2020 with a diagnosis of COVID-19 were tested for markers of hepatitis B (HBsAg, anti-HBc) and C (anti-HCV, HCV RNA) infection. RESULTS: In this period, 4662 patients with COVID-19 were admitted to our centers: 56.3% were male, median age was 76 (0-104) years. Data regarding HBV infection was available in 2915 (62.5%) patients; 253 (8.75%) were anti-HBc+ and 11 (0.38%) HBsAg+. From these, 4 patients did not have a previous diagnosis of hepatitis B, 7 received corticosteroids and one received prophylaxis. There was one HBV reactivation. Anti-HCV was available in 2895 (62%) patients; 24 (0.83%) were positive. From these, 13 patients had a previous hepatitis C diagnosis: 10 patients had been treated with SVR, one achieved spontaneous cure and 2 did not receive treatment. From the 11 previously unknown anti-VHC+patients, 10 had a negative HCV RNA. Overall, only 3 (0.10%) patients tested RNA HCV+. However, none received HCV treatment (2 older than 90 years with comorbidities, 1 died from COVID-19). CONCLUSION: Screening of hepatitis C infection in hospitalized COVID-19 patients seems less useful than expected. The low prevalence of active infection after antiviral treatments and the high age of our population limit the detection of potential candidates for treatment. HBV screening should be aimed to prevent reactivation under immunosuppressive treatments.

New prognosis score including absolute lymphocyte/monocyte ratio, red blood cell distribution width and beta-2 microglobulin in patients with diffuse large B-cell lymphoma treated with R-CHOP: Spanish Lymphoma Group Experience (GELTAMO).

The International Prognostic Index (IPI) is the most widely used score for non-Hodgkin lymphoma but lacks the ability to identify a high-risk population in diffuse large B-cell lymphoma (DLBCL). Low absolute lymphocyte count and high monocytes have proved to be unfavourable factors. Red-cell distribution width (RDW) has been associated with inflammation and beta-2 microglobulin (B2M) with tumour load. The retrospective study included 992 patients with DLBCL treated with R-CHOP. In the multivariate analysis, age, Eastern Cooperative Oncology Group performance status (ECOG-PS), stage, bulky mass, B2M, RDW, and lymphocyte/monocyte ratio (LMR) were independently related to progression-free survival (PFS). A new prognosis score was generated with these variables including age categorized into three groups (0, 1, 2 points); ECOG ≥ 3-4 with two; stage III/IV, bulky mass, high B2M, LMR < 2·25 and RDW > 0·96 with one each; for a maximum of 9. This score could improve the discrimination of a very high-risk subgroup with five-year PFS and overall survival (OS) of 19% and 24% versus 45% and 59% of R (revised)-IPI respectively. This score also showed greater predictive ability than IPI. A new score is presented including complete blood cell count variables and B2M, which are readily available in real-life practice without additional tests. Compared to R-IPI, it shows a more precise high-risk assessment and risk discrimination for both PFS and OS.

RELINF: prospective epidemiological registry of lymphoid neoplasms in Spain. A project from the GELTAMO group.

Lymphomas are a large, heterogeneous group of neoplasms with well-defined characteristics, and this heterogeneity highlights the importance of epidemiological data. Knowledge of local epidemiology is essential to optimise resources, design clinical trials, and identify minority entities. Given there are few published epidemiological data on lymphoma in Spain, the Spanish Lymphoma and Autologous Bone Marrow Transplant Group created the RELINF project. The aim of this project is to determine the frequencies and distribution of lymphoid neoplasms in Spain and to analyse survival. We developed an online platform for the prospective collection of data on newly diagnosed cases of lymphoma in Spain between January 2014 and July 2018; 11,400 patients were registered. Diffuse large B cell lymphoma (DLBCL) and follicular lymphoma (FL) were the most frequent lymphomas in our series. Marginal B cell lymphoma frequency was higher than that reported in other studies, representing more than 11% of mature B cell lymphomas. Peripheral T cell lymphoma not otherwise specified (PTCL-NOS) was the most common subtype of T cell lymphoma, and NK/T cell lymphomas were more frequent than expected (5.4% of total). Hodgkin's lymphoma accounted for 12% of lymphoproliferative syndromes. Overall survival was greater than 90% at 2 years for indolent B cell lymphomas, and approximately 60% for DLBCL, somewhat lower than that previously reported. Survival was poor for PTCL-NOS and angioimmunoblastic T cell lymphoma, as expected; however, it was somewhat better than that in other studies for anaplastic large cell anaplastic lymphoma kinase lymphomas. This is the first prospective registry to report the frequencies, distribution, and survival of lymphomas in Spain. The frequencies and survival data we report here are globally consistent with that reported in other Western countries. These updated frequencies and survival statistics are necessary for developing appropriate management strategies for neoplasias in the Spanish population.

Bendamustine as part of conditioning of autologous stem cell transplantation in patients with aggressive lymphoma: a phase 2 study from the GELTAMO group.

We conducted a phase 2 trial to evaluate the safety and efficacy of bendamustine instead of BCNU (carmustine) in the BEAM (BCNU, etoposide, cytarabine and melphalan) regimen (BendaEAM) as conditioning for autologous stem-cell transplantation (ASCT) in patients with aggressive lymphomas. The primary endpoint was 3-year progression-free survival (PFS). Sixty patients (median age 55 [28-71] years) were included. All patients (except one who died early) engrafted after a median of 11 (9-72) and 14 (4-53) days to achieve neutrophil and platelet counts of >0.5 × 109 /l and >20 × 109 /l, respectively. Non-relapse mortality at 100 days and 1 year were 3.3% and 6.7%, respectively. With a median follow-up of 67 (40-77) months, the estimated 3-year PFS and overall survival (OS) were 58% and 75%, respectively. Patients in partial response at study entry had significantly worse PFS and OS than patients who underwent ASCT in complete metabolic remission, and this was the only prognostic factor associated with both PFS (Relative risk [RR], 0.27 [95% confidence interval {CI} [0.12-0.56]) and OS (RR, 0.40 [95% CI 0.17-0.97]) in the multivariate analysis. BendaEAM conditioning is therefore a feasible and effective regimen in patients with aggressive lymphomas. However, patients not in complete metabolic remission at the time of transplant had poorer survival and so should be considered for alternative treatment strategies.

Physcomitrella patens Activates Defense Responses against the Pathogen Colletotrichum gloeosporioides.

The moss Physcomitrella patens is a suitable model plant to analyze the activation of defense mechanisms after pathogen assault. In this study, we show that Colletotrichum gloeosporioides isolated from symptomatic citrus fruit infects P. patens and cause disease symptoms evidenced by browning and maceration of tissues. After C. gloeosporioides infection, P. patens reinforces the cell wall by the incorporation of phenolic compounds and induces the expression of a Dirigent-protein-like encoding gene that could lead to the formation of lignin-like polymers. C. gloeosporioides-inoculated protonemal cells show cytoplasmic collapse, browning of chloroplasts and modifications of the cell wall. Chloroplasts relocate in cells of infected tissues toward the initially infected C. gloeosporioides cells. P. patens also induces the expression of the defense genes PAL and CHS after fungal colonization. P. patens reporter lines harboring the auxin-inducible promoter from soybean (GmGH3) fused to ß-glucuronidase revealed an auxin response in protonemal tissues, cauloids and leaves of C. gloeosporioides-infected moss tissues, indicating the activation of auxin signaling. Thus, P. patens is an interesting plant to gain insight into defense mechanisms that have evolved in primitive land plants to cope with microbial pathogens.

Comparing R-Bendamustine vs. R-CHOP Plus Maintenance Therapy as First-Line Systemic Treatment in Follicular Lymphoma: A Multicenter Retrospective GELTAMO Study.

Rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) and R-bendamustine (R-B) are the most common frontline treatment strategies for advanced-stage follicular lymphoma (FL). After R-CHOP induction therapy, using rituximab for maintenance therapy notably improves outcomes; however, whether this can be achieved by using the same approach after R-B therapy is still being determined. This retrospective analysis compared 476 FL patients from 17 GELTAMO centers who received R-based regimens followed by rituximab maintenance therapy for untreated advanced-stage FL. The complete response rate at the end of induction was higher with R-B and relapses were more frequent with R-CHOP. During induction, cytopenias were significantly more frequent with R-CHOP and so was the use of colony-stimulating factors. During maintenance therapy, R-B showed more neutropenia and infectious toxicity. After a median follow-up of 81 months (95% CI: 77-86), the 6-year rates of progression-free survival (PFS) were 79% (95% CI: 72-86) for R-bendamustine vs. 67% (95% CI: 61-73) for R-CHOP (p = 0.046), and 6-year overall survival (OS) values were 91% (95% CI: 86-96) for R-B vs. 91% (95% CI: 87-94) for R-CHOP (p = 0.49). In conclusion, R-B followed by rituximab maintenance therapy in patients with previously untreated FL resulted in significantly longer PFS than R-CHOP, with older patients also benefiting from this treatment without further toxicity. Adverse events during maintenance were more frequent with R-B without impacting mortality.

Comparative Study of the Effectiveness of Vedolizumab Versus Ustekinumab After Anti-TNF Failure in Crohn's Disease (Versus-CD): Data from the ENEIDA Registry.

BACKGROUND: Both vedolizumab and ustekinumab are approved for the management of Crohn's disease [CD]. Data on which one would be the most beneficial option when anti-tumour necrosis factor [anti-TNF] agents fail are limited. AIMS: To compare the durability, effectiveness, and safety of vedolizumab and ustekinumab after anti-TNF failure or intolerance in CD. METHODS: CD patients from the ENEIDA registry who received vedolizumab or ustekinumab after anti-TNF failure or intolerance were included. Durability and effectiveness were evaluated in both the short and the long term. Effectiveness was defined according to the Harvey-Bradshaw index [HBI]. The safety profile was compared between the two treatments. The propensity score was calculated by the inverse probability weighting method to balance confounder factors. RESULTS: A total of 835 patients from 30 centres were included, 207 treated with vedolizumab and 628 with ustekinumab. Dose intensification was performed in 295 patients. Vedolizumab [vs ustekinumab] was associated with a higher risk of treatment discontinuation (hazard ratio [HR] 2.55, 95% confidence interval [CI]: 2.02-3.21), adjusted by corticosteroids at baseline [HR 1.27; 95% CI: 1.00-1.62], moderate-severe activity in HBI [HR 1.79; 95% CI: 1.20-2.48], and high levels of C-reactive protein at baseline [HR 1.06; 95% CI: 1.02-1.10]. The inverse probability weighting method confirmed these results. Clinical response, remission, and corticosteroid-free clinical remission were higher with ustekinumab than with vedolizumab. Both drugs had a low risk of adverse events with no differences between them. CONCLUSION: In CD patients who have failed anti-TNF agents, ustekinumab seems to be superior to vedolizumab in terms of durability and effectiveness in clinical practice. The safety profile is good and similar for both treatments.

Screening for Prognostic microRNAs Associated with Treatment Failure in Diffuse Large B Cell Lymphoma.

Diffuse large B cell lymphoma (DLBCL) treatment with R-CHOP regimen produces 5-year progression-free survival and overall survival of around 60-70%. Our objective was to discover prognostic biomarkers allowing early detection of the remaining 30-40% with poor long-term outcome. For this purpose, we applied a novel strategy: from a cohort of DLBCL patients, treated with standard therapy, a discovery group of 12 patients with poor prognosis (advanced stage III-IV, R-IPI > 2) was formed, consisting of six chemoresistant (refractory/early relapse < 12 months) and six chemosensitive (complete remission > 3 years) subjects. By using microarray assays, the most differentially expressed miRNAs were defined as an initial set of prognostic miRNA candidates. Their expression was then analyzed in a validation cohort of 68 patients and the three miRNAs with the most significant impact on event-free and overall survival were selected. In the DLBCL cell line U-2932 the transfection with miR-1244 and miR-193b-5p, but not miR-1231, blocked the effect of CHOP on cell viability. A subsequent gene set enrichment analysis in patients revealed the implication of the first two miRNAs in cell cycle control and chemoresistance-related pathways, whereas the last one was involved in immunological processes. In conclusion, this novel strategy identified three promising prognostic markers for DLBCL patients at high risk of failure with standard therapy.

[Ectopic pregnancy on uterine scar from cesarean section] / Embarazo ectópico sobre cicatriz uterina por cesárea.

Ectopic pregnancy is defined as the implantation of the fertilized egg outside the uterine cavity. About 95% of ectopic pregnancies are located in the tube. Non-tubal forms, in particular on the scar of a cesarean section, are a very rare entity whose early diagnosis and treatment are essential to avoid serious complications and preserve fertility.

El embarazo ectópico se define como la implantación del óvulo fecundado fuera de la cavidad uterina. Alrededor del 95% de los embarazos ectópicos se localizan en la trompa. Las formas no tubáricas, en concreto sobre la cicatriz de una cesárea, son una entidad muy poco frecuente cuyo diagnóstico y tratamiento precoz son imprescindibles para evitar complicaciones graves y preservar la fertilidad.

Total Lesion Glycolysis Improves Tumor Burden Evaluation and Risk Assessment at Diagnosis in Hodgkin Lymphoma.

Hodgkin lymphoma (HL) is a hematological malignancy with an excellent prognosis. However, we still need to identify those patients that could experience failed standard frontline chemotherapy. Tumor burden evaluation and standard decisions are based on Ann Arbor (AA) staging, but this approach may be insufficient in predicting outcomes. We aim to study new ways to assess tumor burden through volume-based PET parameters to improve the risk assessment of HL patients. We retrospectively analyzed 101 patients with HL from two hospitals in the Balearic Islands between 2011 and 2018. Higher metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were significantly associated with a higher incidence of III-IV AA stages, B-symptoms, hypoalbuminemia, lymphopenia, and higher IPS. Standardized uptake value (SUVmax) was significantly related to AA stage and hypoalbuminemia. We found that TLG or the combination of SUVmax, TLG, and MTV significantly improved the risk assessment when compared to AA staging. We conclude that TLG is the best single PET/CT-related tumor-load parameter that significantly improves HL risk assessment when compared to AA staging. If confirmed in a larger and validated sample, this information could be used to modify standard frontline therapy and justifies the inclusion of TLG inside an HL prognostic score.

SEGHI Study: Defining the Best Surveillance Strategy in Hodgkin Lymphoma after First-Line Treatment.

The optimal strategy for early surveillance after first complete response is unclear in Hodgkin lymphoma. Thus, we compared the various follow-up strategies in a multicenter study. All the included patients had a negative positron emission tomography/computed tomography at the end of induction therapy. From January 2007 to January 2018, we recruited 640 patients from 15 centers in Spain. Comparing the groups in which serial imaging were performed, the clinical/analytical follow-up group was exposed to significantly fewer imaging tests and less radiation. With a median follow-up of 127 months, progression-free survival at 60 months of the entire series was 88% and the overall survival was 97%. No significant differences in survival or progression-free survival were found among the various surveillance strategies. This study suggests that follow-up approaches with imaging in Hodgkin lymphoma provide no benefits for patient survival, and we believe that clinical/analytical surveillance for this group of patients could be the best course of action.

Severe infections in patients with lymphoproliferative diseases treated with new targeted drugs: A multicentric real-world study.

BACKGROUND: Lymphoid neoplasms treatment has recently been renewed to increase antitumor efficacy and conventional chemotherapies toxicities. Limited data have been published about the infection risk associated with these new drugs, therefore this study analyzes the infectious complications in patients with lymphoproliferative diseases (LPD) treated with monoclonal antibodies (obinutuzumab, ofatumumab, brentuximab, nivolumab, or pembrolizumab), BTK inhibitors (ibrutinib and acalabrutinib), PI3K inhibitors (idelalisib) and BCL2 inhibitors (venetoclax). METHODS: Multicenter retrospective study of 458 LPD patients treated with targeted therapies in real-life setting, in 18 Spanish institutions, from the time of their commercial availability to August 2020. RESULTS: Severe infections incidence was 23% during 17-month median follow-up; cumulative incidence was higher in the first 3-6 months of targeted drug treatment and then decreased. The most frequent etiology was bacterial (54%). Nine (6%) Invasive fungal infections (IFI) were observed, in its majority in chronic lymphocytic leukemia (CLL) patients treated predominantly with ibrutinib. Significant risk factors for severe infection were: severe lymphopenia (p = 0.009, OR 4.7, range 1.3-1.7), combined targeted treatment vs single agent treatment (p = 0.014 OR 2.2 range 1.1-4.2) and previous rituximab (p = 0.03 OR 1.8, range 1.05-3.3). Infection-related mortality was 6%. In 22% of patients with severe infections, definitive discontinuation of the targeted drug was observed. CONCLUSION: A high proportion of patients presented severe infections during follow-up, with non-negligible attributable mortality, but infection incidence is not superior to the one observed during the chemotherapy era. In selected cases with specific risk factors for infection, antimicrobial prophylaxis should be considered.

Prognostic Role of the Red Blood Cell Distribution Width (RDW) in Hodgkin Lymphoma.

The red blood cell distribution width (RDW) is a parameter available from an automated blood count, which measures the degree of heterogeneity of erythrocyte volume and increases in inflammatory conditions. The prognostic role of RDW has been described in different types of cancers. Hodgkin lymphoma (HL) is a hematological malignancy, known to have a proinflammatory background. We aim to study the prognostic role of RDW in HL. We retrospectively analyzed 264 patients with HL from two hospitals in the Balearic Islands between 1990 and 2018. Higher levels of RDW were independently related to anemia, B-symptoms, and low albumin. In age ≥45 years, the presence of lymphopenia and higher RDW were independently associated with worse event-free survival (EFS) and overall survival (OS). Long-term incidence of secondary malignancies was significantly higher in patients with higher RDW, particularly lung cancer. In conclusion, we report for the first time that RDW is a simple, cheap, and easily available prognostic factor in HL that identifies a group with worse EFS, OS, and a higher potential incidence of secondary malignancies. RDW seems to be related to most adverse prognostic factors in HL, making RDW an excellent candidate to be included in prognostic scores for HL.

Cribado de infección por virus de la hepatitis B y C en pacientes hospitalizados con infección por SARS-CoV-2 / Hepatitis B and C screening in hospitalized patients with SARS-CoV-2 infection

Objetivo: Evaluar el resultado del cribado de hepatitis B y C en pacientes ingresados con COVID-19.Pacientes y métodos: Estudio transversal, prospectivo, realizado en dos hospitales españoles de tercer nivel. Se estudiaron marcadores de hepatitis B (HBsAg, anti-HBc) y C (anti-VHC, ARN VHC) a todos los pacientes hospitalizados con COVID-19 del 1 de marzo al 31 de diciembre de 2020.Resultados: En este periodo ingresaron 4662 pacientes con COVID-19: 56,3% fueron varones, la edad mediana fue 76 (0-104) años. Se realizó serología de hepatitis B a 2915 (62,5%) pacientes; 253 (8,75%) presentaban anti-HBc+y 11 (0,38%) HBsAg+. De los 11 pacientes, 4 desconocían el diagnóstico, 7 recibieron esteroides y uno recibió profilaxis. Hubo un caso de reactivación del VHB. Se determinaron anticuerpos anti-VHC a 2895 (62%) pacientes; 24 (0,83%) fueron positivos. De ellos, 13 pacientes estaban diagnosticados: 10 habían recibido tratamiento, uno se había curado espontáneamente y dos no habían sido tratados. De los 11 restantes, 10 tenían ARN VHC indetectable. En total, solo 3 (0,10%) pacientes tenían carga viral detectable. Sin embargo, ninguno recibió tratamiento (2> 90 años con comorbilidades, uno falleció por COVID-19).Conclusiones: El cribado de hepatitis C en pacientes ingresados por COVID-19 en nuestro medio ha mostrado menor utilidad de la esperada. La baja prevalencia de infección activa tras los tratamientos antivirales y la alta edad mediana de nuestra población limitan la detección de potenciales candidatos a tratamiento. El cribado de hepatitis B debería dirigirse a prevenir la reactivación en pacientes que precisen tratamientos inmunosupresores.(AU)

Analysis of the role of intratecal liposomal cytarabine in the prophylaxis and treatment of central nervous system lymphomatosis: The Balearic Lymphoma Group experience.

Central nervous system (CNS) lymphomatosis is a fatal complication of aggressive non-Hodgkin lymphoma (NHL). In lymphoblastic or Burkitt lymphoma, without specific CNS prophylaxis the risk of CNS relapse is 20-30%. DLBCL has a lower risk of relapse (around 5%) but several factors increase its incidence. There is no consensus or trials to conclude which is the best CNS prophylaxis. Best results seem to be associated with the use of intravenous (iv) high-dose methotrexate (HDMTX) but with a significant toxicity. Other options are the administration of intrathecal (IT) MTX, cytarabine or liposomal cytarabine (ITLC). Our aim is to analyze the experience of the centers of the Balearic Lymphoma Group (BLG) about the toxicity and efficacy of ITLC in the prophylaxis and therapy of CNS lymphomatosis. We retrospectively reviewed cases from 2005 to 2015 (n = 58) treated with ITLC. Our toxicity results were: 33% headache, 20% neurological deficits, 11% nausea, 9% dizziness, 4% vomiting, 4% fever, 2% transient blindness and 2% photophobia. In the prophylactic cohort (n = 26) with a median follow-up of 55 months (17-81) only 3 CNS relapses (11%) were observed (testicular DLBCL, Burkitt and plasmablastic lymphoma, with a cumulative incidence of 8%, 14% and 20% respectively). In the treatment cohort (n = 32), CSF complete clearance was obtained in 77% cases. Median OS was 6 months (0-16). Death causes were lymphoma progression (19 patients, 79%), treatment toxicity (2 patients) and non-related (3 patients, 12%). Toxicity profile was good especially when concomitant dexamethasone was administered. In the prophylactic cohort the incidence of CNS relapse in DLBCL group was similar to previously reported for HDMTX and much better than IT MTX. A high number of ITLC injections was associated with better rates of CSF clearance, clinical responses, PFS and lower relapses. Survival is still poor in CNS lymphomatosis and new therapeutic approaches are still needed.

Chemotherapy-induced nausea and vomiting in acute leukemia and stem cell transplant patients: results of a multicenter, observational study.

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate the incidence and severity of chemotherapy-induced nausea and vomiting (CINV) in oncohematology in routine clinical practice, its impact on quality of life, and caregivers' perception of the extent of the problem. DESIGN AND METHODS: This was a multicenter, prospective, observational follow-up study including: (i) acute myeloid leukemia patients treated with moderately to highly emetogenic chemotherapy and (ii) hematopoietic stem cell transplant recipients, without reduced intensity conditioning. No exclusion criteria were applied. All patients received at least one 5-HT3 antagonist for emesis prophylaxis. Patients recorded emetic episodes and rated nausea daily. Quality of life was assessed through a validated functional living Index-Emesis questionnaire. A survey of caregivers' predictions of CINV was made and the predictions then compared with the observed CINV. RESULTS: One hundred consecutive transplant and 77 acute myeloid leukemia patients were studied. Transplant conditioning was the most important risk factor for CINV: complete response occurred in only 20% of transplant patients (vs. 47% for leukemia patients). Among patients with emesis, the mean percentage of days with emesis and the mean (+/-SD) total number of emetic episodes were 61% and 9.4+/-8.9 (transplant recipients), and 53.6% and 6.2+/-7.3 (leukemia patients), respectively. CINV control was lower in the delayed than in the acute phase. Antiemetic rescue therapy was ineffective. CINV had a deleterious effect on quality of life, especially among transplant recipients. Caregivers underestimated the incidence of delayed nausea and emesis in the transplant setting. INTERPRETATION AND CONCLUSIONS: Despite 5-HT3 antagonist prophylaxis, CINV remains a significant problem in oncohematology, especially in the delayed phase and in transplant recipients.
