The ECHELON-2 Trial: 5-year results of a randomized, phase III study of brentuximab vedotin with chemotherapy for CD30-positive peripheral T-cell lymphoma.

BACKGROUND: For patients with peripheral T-cell lymphoma (PTCL), outcomes using frontline treatment with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP-like therapy are typically poor. The ECHELON-2 study demonstrated that brentuximab vedotin plus cyclophosphamide, doxorubicin, and prednisone (A+CHP) exhibited statistically superior progression-free survival (PFS) per independent central review and improvements in overall survival versus CHOP for the frontline treatment of patients with systemic anaplastic large cell lymphoma or other CD30-positive PTCL. PATIENTS AND METHODS: ECHELON-2 is a double-blind, double-dummy, randomized, placebo-controlled, active-comparator phase III study. We present an exploratory update of the ECHELON-2 study, including an analysis of 5-year PFS per investigator in the intent-to-treat analysis group. RESULTS: A total of 452 patients were randomized (1 : 1) to six or eight cycles of A+CHP (N = 226) or CHOP (N = 226). At median follow-up of 47.6 months, 5-year PFS rates were 51.4% [95% confidence interval (CI): 42.8% to 59.4%] with A+CHP versus 43.0% (95% CI: 35.8% to 50.0%) with CHOP (hazard ratio = 0.70; 95% CI: 0.53-0.91), and 5-year overall survival (OS) rates were 70.1% (95% CI: 63.3% to 75.9%) with A+CHP versus 61.0% (95% CI: 54.0% to 67.3%) with CHOP (hazard ratio = 0.72; 95% CI: 0.53-0.99). Both PFS and OS were generally consistent across key subgroups. Peripheral neuropathy was resolved or improved in 72% (84/117) of patients in the A+CHP arm and 78% (97/124) in the CHOP arm. Among patients who relapsed and subsequently received brentuximab vedotin, the objective response rate was 59% with brentuximab vedotin retreatment after A+CHP and 50% with subsequent brentuximab vedotin after CHOP. CONCLUSIONS: In this 5-year update of ECHELON-2, frontline treatment of patients with PTCL with A+CHP continues to provide clinically meaningful improvement in PFS and OS versus CHOP, with a manageable safety profile, including continued resolution or improvement of peripheral neuropathy.

Brentuximab vedotin and ESHAP is highly effective as second-line therapy for Hodgkin lymphoma patients (long-term results of a trial by the Spanish GELTAMO Group).

BACKGROUND: In this work, we assessed the efficacy and safety of brentuximab vedotin (BV) plus ESHAP (BRESHAP) as second-line therapy for Relapsed/Refractory Hodgkin lymphoma (RRHL) to improve the results before autologous stem-cell transplantation (ASCT). PATIENTS AND METHODS: This was a multicenter, open-label, phase I-II trial of patients with RRHL after first-line chemotherapy. Treatment had three 21-day cycles of etoposide, solumedrol, high-dose AraC, and cisplatin. BV was administered at three dose levels (0.9, 1.2, and 1.8 mg/kg) intravenous on day ‒1 to 3 + 3 cohorts of patients. Final BV dose was 1.8 mg/kg. Responding patients proceeded to ASCT, followed by three BV courses (1.8 mg/kg, every 21 days). Main end points for evaluation were maximum tolerable dose and overall and complete response (CR) before ASCT. RESULTS: A total of 66 patients were recruited (median age 36 years; range 18-66): 40 were primary refractory, 16 early relapse and 10 late relapse. There were 39 severe adverse events were reported in 22 patients, most frequently fever (n = 25, 35% neutropenic), including 3 deaths. Grade 3-4 hematological toxicity presented in 28 cases: neutropenia (n = 21), thrombocytopenia (n = 14), and anemia (n = 7). Grade ≥3-4 extrahematological adverse events (≥5%) were non-neutropenic fever (n = 13) and hypomagnesaemia (n = 3). Sixty-four patients underwent stem-cell mobilization; all collected >2×10e6/kg CD34+ cells (median 5.75; range 2.12-33.4). Overall response before transplant was 91% (CI 84% to 98%), including 70% (CRs 95% CI 59% to 81%). 60 patients were transplanted with no failure engraftments. Post-transplant response was CR in 49 patients (82% CI 73% to 91%) and partial responses in six (10% CI 5% to 15%). After a mean follow-up of 27 months, the 30-month time to treatment to failure was 74% (95% CI 68% to 80%), progression-free survival 71% (95% CI 65% to 77%), and overall survival 91% (CI 84% to 98%). CONCLUSION: BRESHAP looks a safe and effective pre-transplant induction regimen, does not jeopardize transplant and allows long-term remissions and survival.

Immunomodulatory Therapy Does Not Increase the Risk of Cancer in Persons With Inflammatory Bowel Disease and a History of Extracolonic Cancers.

OBJECTIVES: Immunosuppressant therapies (IMTs; thiopurines, anti-tumor necrosis factor agents) may influence the immunologic control of cancer and might facilitate the spread and recurrence of cancer. This study assesses the impact of the use of IMTs on the development of incident cancers (recurrent or new) in patients with inflammatory bowel disease (IBD) and a history of malignancy. METHODS: Patients with IBD included in the ENEIDA registry with a history of cancer without being exposed to IMTs were identified and retrospectively reviewed and compared regarding further treatment with IMTs or not by means of a log-rank test. RESULTS: Overall, 520 patients with previous extracolonic cancer naive to IMTs before the diagnosis of cancer were identified. Of these, 146 were subsequently treated with IMTs (exposed), whereas 374 were not (nonexposed). The proportion of patients with incident cancers was similar in both exposed (16%) and nonexposed (18%) patients (P = 0.53); however, there was more than a 10-year difference in the age at index cancer between these 2 groups. Cancer-free survival was 99%, 98%, and 97% at 1, 2, and 5 years in exposed patients, and 97%, 96%, and 92% at 1, 2, and 5 years in non-exposed patients, respectively (P = 0.03). No differences in incident cancer rates were observed between exposed and nonexposed patients when including only those who were exposed within the first 5 years after cancer diagnosis. DISCUSSION: In patients with IBD and a history of cancer not related to immunosuppression, the use of IMTs is not associated with an increased risk of new or recurrent cancers even when IMTs are started early after cancer diagnosis.

Post-operative morbidity and mortality of a cohort of steroid refractory acute severe ulcerative colitis: Nationwide multicenter study of the GETECCU ENEIDA Registry.

BACKGROUND: Despite the increased use of rescue medical therapies for steroid refractory acute severe ulcerative colitis, mortality related to this entity still remains high. We aimed to assess the mortality and morbidity related to colectomy and their predictive factors in steroid refractory acute severe ulcerative colitis, and to evaluate the changes in mortality rates, complications, indications of colectomy, and the use of rescue therapy over time. METHODS: We performed a multicenter observational study of patients with steroid refractory acute severe ulcerative colitis requiring colectomy, admitted to 23 Spanish hospitals included in the ENEIDA registry (GETECCU) from 1989 to 2014. Independent predictive factors of mortality were assessed by binary logistic regression analysis. Mortality along the study was calculated using the age-standardized rate. RESULTS: During the study period, 429 patients underwent colectomy, presenting an overall mortality rate of 6.3% (range, 0-30%). The main causes of death were infections and post-operative complications. Independent predictive factors of mortality were: age ≥50 years (OR 23.34; 95% CI: 6.46-84.311; p < 0.0001), undergoing surgery in a secondary care hospital (OR 3.07; 95% CI: 1.01-9.35; p = 0.047), and in an emergency setting (OR 10.47; 95% CI: 1.26-86.55; p = 0.029). Neither the use of rescue medical treatment nor the type of surgical technique used (laparoscopy vs. open laparotomy) influenced mortality. The proportion of patients undergoing surgery in an emergency setting decreased over time (p < 0.0001), whereas the use of rescue medical therapy prior to colectomy progressively increased (p > 0.001). CONCLUSIONS: The mortality rate related to colectomy in steroid refractory acute severe ulcerative colitis varies greatly among hospitals, reinforcing the need for a continuous audit to achieve quality standards. The increasing use of rescue therapy is not associated with a worse outcome and may contribute to reducing emergency surgical interventions and improve outcomes.

Extracolonic Cancer in Inflammatory Bowel Disease: Data from the GETECCU Eneida Registry.

OBJECTIVES: The objective of this study was (a) To know the prevalence and distribution of extracolonic cancer (EC) in patients with inflammatory bowel disease (IBD); (b) To estimate the incidence rate of EC; (c) To evaluate the association between EC and treatment with immunosuppressants and anti-tumor necrosis factor (TNF) agents. METHODS: This was an observational cohort study. INCLUSION CRITERIA: IBD and inclusion in the ENEIDA Project (a prospectively maintained registry) from GETECCU. EXCLUSION CRITERIA: Patients with EC before the diagnosis of IBD, lack of relevant data for this study, and previous treatment with immunosuppressants other than corticosteroids, thiopurines, methotrexate, or anti-TNF agents. The Kaplan-Meier method was used to evaluate the impact of several variables on the risk of EC, and any differences between survival curves were evaluated using the log-rank test. Stepwise multivariate Cox regression analysis was used to investigate factors potentially associated with the development of EC, including drugs for the treatment of IBD, during follow-up. RESULTS: A total of 11,011 patients met the inclusion criteria and were followed for a median of 98 months. Forty-eight percent of patients (5,303) had been exposed to immunosuppressants or anti-TNF drugs, 45.8% had been exposed to thiopurines, 4.7% to methotrexate, and 21.6% to anti-TNF drugs. The prevalence of EC was 3.6%. In the multivariate analysis, age (HR=1.05, 95% CI=1.04-1.06) and having smoked (hazards ratio (HR)=1.47, 95% confidence interval (CI)=1.10-1.80) were the only variables associated with a higher risk of EC. CONCLUSIONS: Neither immunosuppressants nor anti-TNF drugs seem to increase the risk of EC. Older age and smoking were associated with a higher prevalence of EC.

Long-Term Efficacy and Safety of Cyclosporine in a Cohort of Steroid-Refractory Acute Severe Ulcerative Colitis Patients from the ENEIDA Registry (1989-2013): A Nationwide Multicenter Study.

OBJECTIVES: To determine the efficacy and safety of cyclosporine (CyA) in a large national registry-based population of patients with steroid-refractory (SR) acute severe ulcerative colitis (ASUC) and to establish predictors of efficacy and adverse events. METHODS: Multicenter study of SR-ASUC treated with CyA, based on data from the ENEIDA registry. SR-ASUC patients treated with infliximab (IFX) or sequential rescue therapy (CyA-IFX or IFX-CyA) were used as comparators. RESULTS: Of 740 SR-ASUC patients, 377 received CyA, 131 IFX and 63 sequential rescue therapy. The cumulative colectomy rate was higher in the CyA (24.1%) and sequential therapy (32.7%) than in the IFX group (14.5%; P=0.01) at 3 months and 5 years. There were no differences in early and late colectomy between CyA and IFX in patients treated after 2005. 62% of patients receiving CyA remained colectomy-free in the long term (median 71 months). There were no differences in mortality between CyA (2.4%), IFX (1.5%) and sequential therapy (0%; P=0.771). The proportion of patients with serious adverse events (SAEs) was lower in CyA (15.4%) than in IFX treated patients (26.5%) or sequential therapy (33.4%; P<0.001). This difference in favor of CyA was maintained when only patients treated after 2005 were analyzed. CONCLUSIONS: Treatment with CyA showed a lower rate of SAE and a similar efficacy to that of IFX thereby supporting the use of either CyA or IFX in SR-ASUC. In addition, the risk-benefit of sequential CyA-IFX for CyA non-responders is acceptable.

Comorbidities, not age, are predictive of survival after autologous hematopoietic cell transplantation for relapsed/refractory Hodgkin's lymphoma in patients older than 50 years.

Autologous hematopoietic cell transplantation (AHCT) is the standard of care for young patients with relapsed/refractory (R/R) Hodgkin's lymphoma (HL). However, there is limited experience of its efficacy and feasibility in older patients. The characteristics and outcomes of 121 patients aged ≥50 years (42 of them are ≥60 years old) with R/R HL who underwent AHCT were reviewed. After a median follow-up of 3.1 years, overall survival (OS) and progression-free survival (PFS) at 5 years were 64 and 55 %, respectively, with no differences between 50-59-year-old and ≥60-year-old patients. Hematological and extra-hematological toxicities after AHCT were comparable between the two groups of age. In univariate analysis, poorer OS and PFS were associated with disease status other than complete remission, hematopoietic cell transplantation comorbidity index (HCT-CI) scores >1, and Charlson Comorbidity Index (CCI) scores >1. HCT-CI scores >1 were also associated with a higher risk of grade 3-4 extrahematologic toxicity. In multivariate analysis, HCT-CI and CCI remained significantly associated with OS and PFS after adjustment for disease status. Our data show that AHCT can be performed in selected patients with R/R HL ≥50 years with acceptable outcome and toxicity. Comorbidities appear to impact AHCT outcome more than age.

Prospective study of prognostic factors in asymptomatic patients with B-cell chronic lymphocytic leukemia-like lymphocytosis: the cut-off of 11 × 10(9)/L monoclonal lymphocytes better identifies subgroups with different outcomes.

The arbitrary threshold of 5 × 10(9)/L chronic lymphocytic leukemia (CLL)-like lymphocytes differentiates monoclonal B lymphocytosis (MBL) from CLL. There are no prospective studies that search for the optimal cut-off of monoclonal lymphocytes able to predict outcome and simultaneously analyze the prognostic value of classic, immunophenotypic, and cytogenetic variables in patients with asymptomatic clonal CLL lymphocytosis (ACL), which includes MBL plus Rai 0 CLL patients. From 2003 to 2010, 231 ACL patients were enrolled in this study. Patients with 11q deletion and atypical lymphocyte morphology at diagnosis had shorter progression-free survival (PFS) (p = 0.007 and p = 0.015, respectively) and treatment-free survival (TFS) (p = 0.009 and p = 0.017, respectively). Elevated beta-2 microglobulin (B2M) also correlated with worse TFS (p = 0.002). The optimal threshold of monoclonal lymphocytes independently correlated with survival was 11 × 10(9)/L (p = 0.000 for PFS and p = 0.016 for TFS). As conclusion, monoclonal lymphocytosis higher than 11 × 10(9)/L better identifies two subgroups of patients with different outcomes than the standard cut-off value of 5 × 10(9)/L. Atypical lymphocyte morphology, 11q deletion and elevated B2M had a negative impact on the survival in ACL patients.

Bendamustine as salvage treatment for patients with relapsed or refractory mantle cell lymphoma patients: a retrospective study of the Spanish experience.

Patients with mantle cell lymphoma (MCL) have an adverse outcome after relapse. Bendamustine has demonstrated a good efficacy and toxicity profile in previously reported trials. In this study, we present a retrospective analysis of the Spanish experience in relapsed/refractory MCL treated with bendamustine in combination or alone with the objective of knowing the efficacy and toxicity profile of this treatment in our current clinical practice. Fifty eight patients were registered: 67 % male with median age of 71 years, and 2 is the median number of previous lines. The most frequent bendamustine regimen was bendamustine plus rituximab (83 %). The median number of cycles was 5 (range 1-8). The overall response rate was 84 % with 53 % of complete response/unconfirmed complete response (CR/uCR). Median progression-free survival (PFS) was 16 months (95 % confidence interval (CI) 13.3-18.8), and for patients who achieved CR/uCR, it was 33 months (95 % CI 11.1-54.2). Median overall survival (OS) was 30 months (95 % CI 25.6-34.9). For PFS, only blastoid histology and not achieving CR after bendamustine had a significant negative impact on the univariate and multivariate analyses (p < 0.05). Nevertheless, for OS, only an elevated lactate dehydrogenase (LDH) had negative impact on both, univariate and multivariate analyses (p < 0.05). Only one case of treatment-related mortality in a 79-year-old patient with very bad performance status was reported. In 280 cycles, 12 (4 %) hospitalizations for febrile neutropenia were reported. In our population, bendamustine has been a good salvage treatment with a favorable toxicity profile in a non selected and heavily pretreated population of patients with MCL.

The role of allogeneic stem cell transplantation in Hodgkin's lymphoma.

OPINION STATEMENT: The treatment of patients with classical Hodgkin's lymphoma relapsing after autologous stem cell transplantation represents a clear unmet need. Overall long-term outcome is not the same in these patients and therapeutic options in this setting are very heterogeneous and include salvage CT and/or RT followed or not by a second stem cell transplantation, palliative care, new drugs, or biological agents. Despite the absence of prospective, randomized, clinical trials, allogeneic stem cell transplantation either from a HLA identical sibling or a matched, unrelated donor represents an attractive option for those young patients with chemosensitive disease after being treated with a salvage protocol. The use of reduced intensity conditioning regimens has been able to drastically decrease nonrelapse mortality, although relapse rate remains a significant issue in this setting. More intense conditioning protocols could eventually decrease the relapse rate after the allogeneic procedure and, as indicated by a recent retrospective analysis of the Lymphoma Working Party of the European Group for Blood and Marrow Transplantation, nonrelapse mortality does not represent a major problem nowadays for patients with multiply relapsed Hodgkin's lymphoma. Brentuximab vedotin is an antibody-drug conjugate that selectively delivers monomethyl auristatin E, an antimicrotubule agent, into CD30-expressing cells. Its use has been approved recently for patients with Hodgkin's lymphoma relapsing after autologous stem cell transplantation. As a single dose, brentuximab vedotin is able to achieve an objective response rate of 75 % with 34 % of the patients achieving a complete remission. Its widespread use will most certainly change the treatment paradigm of this subgroup of patients, either avoiding the allogeneic procedure in some patients or by increasing the group of potential candidates to an allogeneic transplant being used as a "bridge to allo." Additional information on long-term outcome of patients being treated with this drug or the development of prospective clinical trials in this setting will most probably give some light to this question we have nowadays.

Safety and effectiveness of direct-acting antiviral drugs in the treatment of hepatitis C in patients with inflammatory bowel disease.

BACKGROUND AND AIMS: Hepatitis C virus (HCV) management in Inflammatory Bowel Disease (IBD) is uncertain. The ECCO guidelines 2021 recommended HCV treatment but warn about the risk of IBD reactivation. We aimed to evaluate 1) the effectiveness and safety of direct-acting antivirals (DAAs) in IBD; 2) the interaction of DAAs with IBD drugs. METHODS: Multicentre study of IBD patients and HCV treated with DAAs. Variables related to liver diseases and IBD, as well as adverse events (AEs) and drug interactions, were recorded. McNemar's test was used to assess differences in the proportion of active IBD during the study period. RESULTS: We included 79 patients with IBD and HCV treated with DAAs from 25,998 IBD patients of the ENEIDA registry. Thirty-one (39.2 %) received immunomodulators/biologics. There were no significant differences in the percentage of active IBD at the beginning (n = 11, 13.9 %) or at the 12-week follow-up after DAAs (n = 15, 19 %) (p = 0.424). Sustained viral response occurred in 96.2 % (n = 76). A total of 8 (10.1 %) AEs occurred and these were unrelated to activity, type of IBD, liver fibrosis, immunosuppressants/biologics, and DAAs. CONCLUSIONS: We demonstrate a high efficacy and safety of DAAs in patients with IBD and HCV irrespective of activity and treatment of IBD.

Safety of thiopurines and anti-TNF-α drugs during pregnancy in patients with inflammatory bowel disease.

OBJECTIVES: The safety of thiopurines and anti-tumor necrosis factor-α (TNF-α) drugs during pregnancy remains controversial, as the experience with these drugs in this situation is limited. Our aim is to assess the safety of thiopurines and anti-TNF-α drugs for the treatment of inflammatory bowel disease (IBD) during pregnancy. METHODS: Retrospective, multicenter study in IBD patients. Pregnancies were classified according to the therapeutic regimens during pregnancy or during the 3 months before the conception: non-exposed group, pregnancies exposed to thiopurines alone (group A), and pregnancies exposed to anti-TNF-α drugs (group B). An unfavorable Global Pregnancy Outcome (GPO) was considered if pregnancy developed with obstetric complications in the mother and in the newborn. RESULTS: A total of 187 pregnancies in the group A, 66 pregnancies in the group B, and 318 pregnancies in the non-exposed group were included. The rate of unfavorable GPO was different among the three groups (31.8% in non-exposed group, 21.9% in group A, and 34.8% in group B), being lower in pregnancies under thiopurines than among non-exposed (P = 0.01). The rate of pregnancy complications was similar among the three groups (27.7% in non-exposed, 20.9% in group A, and 30.3% in group B). The rate of neonatal complications was different among the three groups (23.3% in non-exposed group, 13.9% in group A, and 21.2% in group B), being lower in pregnancies under thiopurines than among non-exposed (P = 0.01). In the multivariate analysis, the treatment with thiopurines (odds ratio = 0.6; 95% confidence interval = 0.4-0.9, P = 0.02) was the only predictor of favorable GPO, whereas maternal age >35 years at conception was the only predictor of unfavorable GPO. The treatment with anti-TNF-α drugs was not associated with an unfavorable GPO. CONCLUSION: The treatment with thiopurines and anti-TNF-α drugs does not seem to increase the risk of complications during pregnancy and does seem to be safe for the newborn.

Risk assessment of Cryptosporidium intake in drinking water treatment plant by a combination of predictive models and event-tree and fault-tree techniques.

Risk-informed decision making permits a more effective water safety management. In this framework, this article introduces the rationale and proposes a new approach to carry out a quantitative risk assessment along the water chain, from river source to tap water, by integrating predictive modelling combined with event-tree and fault-tree techniques. The model developed by this approach could not only account for normal but also for abnormal process conditions in the water treatment plant, as well as assess the real impact of the applied safety controls, such as turbidity control. A sensitivity study was conducted to determine the effect of considering a typical drinking water treatment plant (DWTP), i.e. coagulation, sedimentation and filtration with two turbidity controls (on intake and after filtration) on the risk of infection due to exposure to Cryptosporidium in tap water. The results showed that, with the current effectiveness of turbidity reduction in the DWTP, the first control did not minimise the annual risk of Cryptosporidium infection (3.6E-04) and only limiting turbidity after filtration to below 0.01NTU provided a clear reduction in risk (7.7E-05) at the cost of rejecting 60 % of the water after the control. The lowest risk was found when turbidity reduction was set at 4 logs (8.48E-06), although this means that the effectiveness of turbidity reduction should be greatly improved. It was therefore concluded that supplementing the current treatment with alternative barriers such as UV or ozone disinfection and/or implementing direct control of Cryptosporidium concentration should be considered.

Real-world use of mycophenolate mofetil in inflammatory bowel disease: Results from the ENEIDA registry.

BACKGROUND: Studies to evaluate the use of mycophenolate mofetil (MMF) in inflammatory bowel disease (IBD) are limited after the appearance of biological treatments. AIMS: Our primary objective was to evaluate the effectiveness and safety of MMF in IBD. METHODS: IBD patients who had received MMF were retrieved from the ENEIDA registry. Clinical activity as per the Harvey-Bradshaw Index (HBI), partial Mayo score (pMS), physician global assessment (PGA) and C-reactive protein (CRP) were reviewed at baseline, at 3 and 6 months, and at final follow-up. Adverse events and causes of treatment discontinuation were documented. RESULTS: A total of 83 patients were included (66 Crohn's disease, 17 ulcerative colitis), 90% of whom had previously received other immunosuppressants. In 61% of patients systemic steroids were used at initiation of MMF, and in 27.3% biological agents were co-administered with MMF. Overall clinical effectiveness was observed in 64.7% of the population. At the end of treatment, 45.6% and 19.1% of subjects showed remission and clinical response, respectively. MMF treatment was maintained for a median of 28.9 months (IQR: 20.4-37.5). CONCLUSION: Our study suggests, in the largest cohort to date, that MMF may be an effective alternative to thiopurines and methotrexate in IBD.

Simplified risk-prediction for benchmarking and quality improvement in emergency general surgery. Prospective, multicenter, observational cohort study.

BACKGROUND AND AIMS: Emergency General Surgery (EGS) conditions account for millions of deaths worldwide, yet it is practiced without benchmarking-based quality improvement programs. The aim of this observational, prospective, multicenter, nationwide study was to determine the best benchmark cutoff points in EGS, as a reference to guide improvement measures. METHODS: Over a 6-month period, 38 centers (5% of all public hospitals) attending EGS patients on a 24-h, 7-days a week basis, enrolled consecutive patients requiring an emergent/urgent surgical procedure. Patients were stratified into cohorts of low (i.e., expected morbidity risk <33%), middle and high risk using the novel m-LUCENTUM calculator. RESULTS: A total of 7258 patients were included; age (mean ± SD) was 51.1 ± 21.5 years, 43.2% were female. Benchmark cutoffs in the low-risk cohort (5639 patients, 77.7% of total) were: use of laparoscopy ≥40.9%, length of hospital stays ≤3 days, any complication within 30 days ≤ 17.7%, and 30-day mortality ≤1.1%. The variables with the greatest impact were septicemia on length of hospital stay (21 days; adjusted beta coefficient 16.8; 95% CI: 15.3 to 18.3; P < .001), and respiratory failure on mortality (risk-adjusted population attributable fraction 44.6%, 95% CI 29.6 to 59.6, P < .001). Use of laparoscopy (odds ratio 0.764, 95% CI 0.678 to 0.861; P < .001), and intraoperative blood loss (101-500 mL: odds ratio 2.699, 95% CI 2.152 to 3.380; P < .001; and 500-1000 mL: odds ratio 2.875, 95% CI 1.403 to 5.858; P = .013) were associated with increased morbidity. CONCLUSIONS: This study offers, for the first time, clinically-based benchmark values in EGS and identifies measures for improvement.

A real-life overview of a hematopoietic cell transplant program throughout a four-year period, including prospective registry, exclusion causes and final donor selection.

Traceability of patients who are candidates for Hematopoietic cell transplant (HCT) is crucial to ensure HCT program quality. Continuous knowledge of both a detailed registry from a HCT program and final exclusion causes can contribute to promoting a real-life vision and optimizing patient and donor selection. We analyzed epidemiological data reported in a 4 year-monocentric prospective registry, which included all patients presented as candidates for autologous (Auto) and/or allogeneic (Allo) HCT. A total of 543 patients were considered for HCT: 252 (42.4%) for Allo and 291 (57.6%) for Auto. A total of 98 (38.9%) patients were excluded from AlloHCT due to basal disease progression more commonly (18.2%). Seventy-six (30.2%) patients had an HLA identical sibling, whereas 147 (58.3%) patients had only Haplo. UD research was performed in 106 (42%) cases, significantly more often in myeloid than lymphoid malignancies (57% vs 28.7%, p < 0.001) but 61.3% were finally canceled, due to donor or disease causes in 72.4%. With respect to Auto candidates, a total of 60 (20.6%) patients were finally excluded; progression was the most common cause (12%). Currently, Haplo is the most frequent donor type. The high cancellation rate of UD research should be revised to optimize further donor algorithms.

Liver dysfunction related to hepatitis B and C in patients with inflammatory bowel disease treated with immunosuppressive therapy.

BACKGROUND: There is no information about the frequency of liver dysfunction in patients with inflammatory bowel disease (IBD) treated with immunosuppressants and infected with hepatitis B (HBV) and/or C virus (HCV). AIM: To assess the influence of immunosuppressants on the course of HBV and HCV infection in IBD. METHODS: Patients with IBD with HBV and/or HCV infection from 19 Spanish hospitals were included. Clinical records were reviewed for the type of immunosuppressant used, treatment duration, liver function tests and viral markers before, during and after each immunosuppressant. Logistic and Cox regression analysis were used to identify predictors of outcome. RESULTS: 162 patients were included; 104 had HBV markers (25 HBsAg positive) and 74 had HCV markers (51 HCV-RNA positive), and 16 patients had markers of both infections. Liver dysfunction was observed in 9 of 25 HBsAg positive patients (36%), 6 of whom developed hepatic failure. Liver dysfunction in HCV was observed in 8 of 51 HCV-RNA positive patients (15.7%), and only one developed hepatic failure. The frequency and severity of liver dysfunction was significantly higher in HBV-infected patients than in HCV-infected patients (p=0.045 and p=0.049, respectively). Treatment with ≥2 immunosuppressants was an independent predictor of HBV reactivation (OR 8.75; 95% CI 1.16 to 65.66). The majority of patients without reactivation received only one immunosuppressant for a short period and/or prophylactic antiviral treatment. No definite HBV reactivations were found in anti-HBc positive patients lacking HBsAg. CONCLUSION: Liver dysfunction in patients with IBD treated with immunosuppressants is more frequent and severe in those with HBV than in HCV carriers and is associated with combined immunosuppression.

Allogeneic hematopoietic stem cell transplantation for advanced mycosis fungoides and Sézary syndrome. An updated experience of the Lymphoma Working Party of the European Society for Blood and Marrow Transplantation.

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative treatment option in advanced-stage mycosis fungoides (MF) and Sézary syndrome (SS). This study presents an updated analysis of the initial experience of the Lymphoma Working Party of the European Society for Blood and Marrow Transplantation (EBMT) describing the outcomes after allo-HSCT for MF and SS, with special emphasis on the impact of the use of unrelated donors (URD). METHODS AND PATIENTS: Eligible for this study were patients with advanced-stage MF or SS who underwent a first allo-HSCT from matched HLA-identical related or URD between January/1997 and December/2011. Sixty patients have been previously reported. RESULTS: 113 patients were included [77 MF (68%)]; 61 (54%) were in complete or partial remission, 86 (76%) received reduced-intensity protocols and 44 (39%) an URD allo-HSCT. With a median follow up for surviving patients of 73 months, allo-HSCT resulted in an estimated overall survival (OS) of 38% at 5 years, and a progression-free survival (PFS) of 26% at 5 years. Multivariate analysis demonstrated that advanced-phase disease (complete remission/partial remission >3, primary refractory or relapse/progression in patients that had received 3 or more lines of systemic treatment prior to transplant or the number of treatment lines was not known), a short interval between diagnosis and transplant (<18 months) were independent adverse prognostic factors for PFS; advanced-phase disease and the use of URDs were independent adverse prognostic factors for OS. CONCLUSIONS: This extended series supports that allo-HSCT is able to effectively rescue over one third of the population of patients with advanced-stage MF/SS. High relapse rate is still the major cause of failure and needs to be improved with better strategies before and after transplant. The negative impact of URD is a matter of concern and needs to be further elucidated in future studies.

Endoscopist experience as a risk factor for colonoscopic complications.

AIM: We aimed to determine the incidence of colonic perforation (CP) following colonoscopy and postpolypectomy bleeding (PPB) in a teaching hospital, assessing the influence of endoscopist experience as a risk factor. METHOD: All colonoscopies performed between 1995 and 2008 were reviewed. Demographic data, endoscopic procedure information, incidence of CP and PPB, and endoscopist experience were recorded. RESULTS: In the 14-year period, 25,214 endoscopic colonic procedures were performed, and 3991 patients underwent polypectomy. The overall CP risk was 0.51/1000 procedures; and PPB 14.7/1000. The relative risk (RR) ratio of complications was 2.8/1000 procedures. The RR rate was highest for endoscopists performing less than 591 procedures per year (4.0/1000 [95% CI, 3.7-4.3] vs 2.9/1000 [95% CI, 2.6-3.2]), P < 0.001). CONCLUSION: The complication rate after colonoscopy was comparable to that previously reported. Colonoscopy carried out by a low-volume endoscopist was independently associated with bleeding and perforation.
