RESUMEN

OBJECTIVE: Perfluoroalkyl substances (PFAS) are chemicals widely employed in the industry. Long term consequences of the newborns' contamination by PFAS on thyroid function are of concern. The aim of this study is to assess the potential associations between PFAS contamination measured at birth and thyroid function assessed few months later. PFAS levels were previously determined in cord blood from a cohort of newborns recruited in Liege. METHOD: Parents of the children belonging to the first and the fifth quintiles of exposure to PFAS were contacted in order to measure the thyroid stimulating hormone (TSH) levels in their child few months after birth. Twenty-eight children participated in the study. Moreover, we performed a literature review about associations between pre- or perinatal exposure to persistent organic pollutants and thyroid function during early childhood. RESULT: No significant difference was highlighted between both groups of contamination (Mann-Whitney, p-value = 0.91). Literature review highlighted the critical need of new longitudinal data about this problematic. CONCLUSION: Our results suggest that the PFAS levels at birth are not associated with TSH levels later in life. Large scale studies are required to confirm our results.


Objectif : Notre but est d'étudier les associations potentielles entre contamination par les composés perfluorés (PFC) mesurée à la naissance et fonction thyroïdienne évaluée quelques mois plus tard. Les niveaux de PFC ont été déterminés précédemment dans le sang de cordon de nouveau-nés recrutés à Liège. Méthode : Les parents des enfants appartenant au premier et cinquième quintiles d'exposition aux PFC ont été contactés pour mesurer les niveaux de thyréostimuline (TSH) chez leurs enfants quelques mois après la naissance. Vingt-huit enfants ont été recrutés. De plus, nous avons réalisé une revue de littérature concernant les associations entre exposition pré- ou périnatale aux polluants organiques persistants (POP) et fonction thyroïdienne pendant la petite enfance. Résultat : Aucune différence significative n'a été mise en évidence entre les deux groupes de contamination (Mann-Whitney, p = 0,91). Selon, la revue de la littérature, il est indispensable de disposer de nouvelles données longitudinales relatives à la relation entre contamination par les POP et fonction thyroïdienne. Conclusion : Nos résultats suggèrent que les concentrations de PFC à la naissance ne sont pas associées aux niveaux de TSH au cours de la vie. Des études basées sur de plus grandes cohortes sont requises pour confirmer nos résultats.

RESUMEN

PURPOSE: Malnutrition is a predictor of poor outcomes in patients with cancer. Little is known about the benefit of nutritional support in these patients. The purpose of this study was to assess the impact of home parenteral nutrition (HPN) on quality of life (Qol) in cancer patients. METHODS: We performed an observational prospective study to determine the impact of HPN on Qol in a population of patients with heterogeneous cancer. Physicians, patients and family members had to complete a questionnaire before HPN administration and 28 days after the course of HPN. Qol was evaluated using the self-administered questionnaire FACT-G. RESULTS: We included 767 patients with cancer of whom 437 ended the study. Mean patient age was 63±11.4 years and 60.5% were men. Primary gastrointestinal cancer was reported in 50% of patients and 65.3% were presenting metastases. Malnutrition was reported in 98.3%. After 28 days of HPN intake, significant improvement was observed in the Qol (49.95±5.82 vs. 48.35±5.01 at baseline, p<0.0001). The mean weight, serum albumin and the nutrition risk index had also improved significantly. Most patients (78%) had perceived a positive impact of the HPN. A significant improvement in patient's well-being was perceived also by family members and physicians. CONCLUSIONS: Our data suggest that preventing and correcting malnutrition using HPN in patients with cancer might have a significant benefit on their well-being. Randomized controlled studies are required to confirm this finding.

RESUMEN

Identify prognostic factors for survival and patterns of treatment failure after definitive radiochemotherapy for esophageal cancer. Between 2003 and 2006, 143 patients with squamous cell carcinoma and adenocarcinoma of the esophagus were retrospectively reviewed. Median age was 65 years (42-81). Median radiation dose was 62.5 Gy (38-72) with 1.8-2 Gy fraction. Median follow-up was 20.8 months (2.8-92.4). Three and 5-year local recurrence-free survival rates were 58.3% and 50.9%. In univariate analysis, traversable esophageal stricture was a prognostic factor. Three, 5-year locoregional recurrence-free survival rates were 42.4% and 34.9%. In multivariate analysis, traversable esophageal stricture and stage < IIB were independent prognostic factors. Three and 5-year disease-free survival rates were 30.5% and 25.9%. In multivariate analysis, Nutritional Risk Index (NRI) ≥ 97.5 and performance status (PS) = 0 were independent prognostic factors. Median, 3, and 5-year overall survival rates were 22.1 months, 34.4%, and 19.8%. In multivariate analysis, independent prognostic factors were NRI ≥ 97.5 and PS = 0. Median survival times for the NRI classes (no denutrition, moderate and severe denutrition) were 29.5, 19.7, and 12 months (P = 0.0004), respectively. A major impact of baseline NRI was found in terms of survival; it should be included in future prospective trials.

RESUMEN

White dwarfs represent the endpoint of stellar evolution for stars with initial masses between approximately 0.07 and 8-10, where is the mass of the Sun (more massive stars end their life as either black holes or neutron stars). The theory of stellar evolution predicts that the majority of white dwarfs have a core made of carbon and oxygen, which itself is surrounded by a helium layer and, for approximately 80 per cent of known white dwarfs, by an additional hydrogen layer. All white dwarfs therefore have been traditionally found to belong to one of two categories: those with a hydrogen-rich atmosphere (the DA spectral type) and those with a helium-rich atmosphere (the non-DAs). Here we report the discovery of several white dwarfs with atmospheres primarily composed of carbon, with little or no trace of hydrogen or helium. Our analysis shows that the atmospheric parameters found for these stars do not fit satisfactorily in any of the currently known theories of post-asymptotic giant branch evolution, although these objects might be the cooler counterpart of the unique and extensively studied PG 1159 star H1504+65 (refs 4-7). These stars, together with H1504+65, might accordingly form a new evolutionary sequence that follows the asymptotic giant branch.

RESUMEN

Cambodia, a country of 14 million inhabitants, was devastated during the Khmer Rouge period and thereafter. The resources of treatment are rare: only one radiotherapy department, renovated in 2003, with an old cobalt machine; few surgeons trained to operate on cancer patients; no hematology; no facilities to use intensive chemotherapy; no nuclear medicine department and no palliative care unit. Cervical cancer incidence is one of the highest in the world, while in men liver cancer ranks first (20% of all male cancers). Cancers are seen at stage 3 or 4 for 70% of patients. There is no prevention program - only a vaccination program against hepatitis B for newborns - and no screening program for cervical cancer or breast cancer. In 2010, oncology, recognized as a full specialty, was created to train the future oncologists on site at the University of Phnom Penh. A new National Cancer Center will be built in 2013 with modern facilities for radiotherapy, medical oncology, hematology and nuclear medicine. Cooperation with foreign countries, especially France, and international organizations has been established and is ongoing. Progress is occurring slowly due to the shortage of money for Cambodian institutions and the lay public.

RESUMEN

PURPOSE: Cutaneous adverse events induced by epidermal growth factor receptor (EGFR) inhibitors can hamper the patients' quality of life. The aim of our work was to draft an algorithm for the optimised management of this skin toxicity. METHODS: This algorithm was built in three steps under the responsibility of a steering committee. Step I: a systematic literature analysis (SLA) has been performed. Step II: the collection of information about practices was performed through a questionnaire.These questions were asked during regional meetings to which oncologists, gastro-enterologists, radiotherapists, and dermatologists were invited. Step III: a final meeting was organised involving the bibliography group and the steering committee and regional scientific committees for proposing a final algorithm. RESULTS: Step I: 14 publications were selected to evaluate the use of cyclines as curative or prophylactic treatment of the folliculitis induced by EGFR inhibitors. Nineteen publications were retained for the topical treatment of the folliculitis. Forty-six articles were selected for the management of the cutaneous lesions in link with appendages and 12 for xerosis and pruritus. Step II: 96 delegates attended the seven regional meetings and 67 questionnaires were analysed. Step III: a final algorithm was proposed on the basis of the conclusions of the first two steps and expert opinions present at this final meeting. The different propositions were unanimously approved by the 14 experts who voted. CONCLUSIONS: This multidisciplinary study summarising published data and current practices produced a therapeutic algorithm, which should facilitate the standardised, optimised management of skin toxicity associated with EGFR inhibitors in France.

RESUMEN

This study describes concentrations of Pregnancy Associated Glycoproteins (PAG), progesterone (P4), estrone (E1) and estrone-sulfate (E1S) in American Bison sera. In 2 ranches, mature American Bison were sampled once a year for 2 yr. Subsequent American Bison cows calving days were reported. PAG concentration was determined by Radio-Immuno Assay, whereas P4, E1 and E1S were assayed using Liquid Chromatography and Mass Spectrometry. Concentrations were compared between American Bison bulls (B, n = 7), Nonpregnant cows (NP, n = 32), first (1TP, n = 3), second (2TP, n = 26) and third (3TP, n = 15) trimester of pregnancy. Seven American Bison bulls and 92 cows were sampled, 51 calved during these 2 yr. Calving occurred mostly in spring (74.5%), but also in summer (13.7%) and fall (11.8%). PAG and P4 were higher in 2TP and 3TP than B and NP (P< 0.0001). P4 was non-basal in B and NP. E1 and E1S were correlated (P< 0.0001; r = 0.76) and increased in 2TP and 3TP when compared with B and NP (P< 0.01). Moreover, E1S was higher in 3TP than in 2TP (P< 0.0001) and correlated to pregnancy day (P< 0.0001; r = 0.60). Breeding American Bison in Belgium induces a calving seasonality loss. P4 slowly increases in 1TP and remains steady and high in 2 and 3TP. P4 non-basal and variable concentrations in B or NP disable its use as gestation marker. American Bison produce PAG in the 2 and 3TP, but Estrone-sulfate assay seems to be the best pregnancy marker during the 2 last trimesters as it could help to estimate the gestation period.

RESUMEN

Tidal disruption and subsequent accretion of planetesimals by white dwarfs can reveal the elemental abundances of rocky bodies in exoplanetary systems. Those abundances provide information on the composition of the nebula from which the systems formed, which is analogous to how meteorite abundances inform our understanding of the early Solar System. We report the detection of lithium, sodium, potassium, and calcium in the atmosphere of the white dwarf Gaia DR2 4353607450860305024, which we ascribe to the accretion of a planetesimal. Using model atmospheres, we determine abundance ratios of these elements, and, with the exception of lithium, they are consistent with meteoritic values in the Solar System. We compare the measured lithium abundance with measurements in old stars and with expectations from Big Bang nucleosynthesis.

RESUMEN

Biomarkers are well established for the diagnosis of myocardial infarction, heart failure and cardiac fibrosis. Different papers on cardiac biomarker evolution during exercise have been published in the literature and generally show mild to moderate elevations. However, the mechanism responsible for these elevations, reflecting physiological or even pathophysiological changes, still has to be clearly elucidated. There are also indications of higher cardiac risk in poorly trained athletes than in well-trained athletes. Whether regular repetition of intensive exercise might lead, in the longer term, to fibrosis and heart failure remains to be determined. In this review, we summarized the main research about the effects of intense exercise (in particular, running) on cardiac biomarkers (including troponins, natriuretic peptides, etc.). We found that cardiac fibrosis biomarkers seemed to be the most informative regarding the biological impact of intense physical activity.

RESUMEN

OBJECTIVE: To evaluate the efficacy and toxicity of pegylated liposomal doxorubicin (PLD; Caelyx)-cyclophosphamide combination in older metastatic breast cancer patients. METHODS: A multicenter phase II trial was conducted. Inclusion criteria were age 65-75 years, ECOG 0-1 and left ventricular ejection fraction > or =50%. First-line chemotherapy was given to metastatic breast cancer patients resistant to hormonal therapy. The treatment schedule was PLD 40 mg/m(2) and cyclophosphamide 500 mg/m(2) on day 1 every 4 weeks. Efficacy was the primary endpoint, while response duration and tolerance were the secondary endpoints. RESULTS: Thirty-five patients (median age 71.3 years) were enrolled. No treatment-related death, no congestive heart failure or decrease in left ventricular ejection fraction and no febrile neutropenia were reported. TOXICITY: grade 3 dyspnea was found in 1 patient, neutropenia in 11 patients (7 grade 3, 4 grade 4), grade 3 mucositis in 4 patients, grade 3 hand-foot syndrome in 1 patient and a generalized rash in 1 patient. An objective response (complete and partial response) was achieved in 10 (28.6%) patients and disease control in 24 (69%) with a progression-free survival of 8.8 months and a median overall survival of 20.3 months. CONCLUSION: The PLD-cyclophosphamide combination is moderately active and safe in elderly metastatic breast cancer patients, but cannot be recommended routinely due to myelotoxicity and mucositis hazards.

RESUMEN

BACKGROUND/AIMS: To compare the cost consequences of oral capecitabine and two different intravenous regimens of 5-fluorouracil/folinic acid (de Gramont and Mayo Clinic regimens) as adjuvant therapy in stage III colon cancer in France. METHODS: Clinical efficacy and safety data were taken from published clinical trials. Medical resource use was estimated from published data and expert opinion. Direct costs (drug acquisition, inpatient and home drug administration, laboratory tests, transportation, and management of adverse events) were considered over a time horizon of 46 months (3.8 years). The perspective taken was that of the French Sickness Funds. RESULTS: In patients treated with capecitabine, relapse-free survival was 1.3 months longer than with the Mayo Clinic regimen, which has been shown to be as effective as the de Gramont regimen. In the base case analysis, capecitabine was less costly (3,654 EUR/patient) than the Mayo Clinic (10,481 EUR/ patient) and de Gramont (7,204 EUR/patient) regimens. In the sensitivity analysis, capecitabine remained dominant except when the intravenous regimens were assumed to be administered at home in all patients. CONCLUSIONS: In France, capecitabine is more effective and less costly than both the Mayo Clinic and de Gramont regimens as adjuvant therapy for colon cancer.

RESUMEN

OBJECTIVES: Fetal macrosomia is a common complication of maternal diabetes mellitus and is associated with substantial morbidity, but the precise cellular and molecular mechanisms that induce fetal macrosomia are not well understood. The imprinted genes IGF-II and H19 are crucial for placental development and fetal growth. The term placentas from diabetic pregnancies express more insulin-like growth factor II (IGF-II) than those from normal pregnancies. Deregulation of their imprinting status is observed in the macrosomia-associated syndrome, the Beckwith-Wiedemann syndrome. The aim of this study was to determine whether loss of imprinting hence biallelic expression was also a hallmark of macrosomia in diabetic pregnancies. DESIGN AND METHODS: IGF-II and H19 maternal and paternal expressions were studied in placentas from two groups of type 1 diabetic mothers: one with macrosomic babies and the other with babies of normal weight. Maternal or paternal allele specific expressions were defined by using DNA polymorphic markers of the IGF-II and H19 genes. RFLP analysis was performed on PCR products from genomic DNA of the father, the mother and the child, and on RT-PCR products from placental mRNA. RESULTS: RFLP analysis showed that the IGF-II gene remains paternally expressed and the H19 gene remains maternally expressed in all placentas examined, independently of the birth weight status. CONCLUSIONS: These results suggest that, in contrast with Beckwith-Wiedemann syndrome-associated macrosomia, loss of imprinting for IGF-II or H19 is not a common feature of diabetic pregnancies associated with macrosomia.

RESUMEN

PURPOSE: To evaluate the outcome of patients treated for soft tissue sarcoma using three different post-operative radiotherapy schedules. METHODS AND MATERIALS: Between 1990 and 2003, 89 patients (median age 50.8 years) presenting with soft tissue sarcoma (located to the limbs for 66 of them) underwent post-conservative-surgery radiotherapy. Pathology was liposarcoma in 35 cases and 54 others tumors. Tumors grades (FNCLCC classification) were 1, 2, 3 or unknown in 29, 32, 19 and 9 cases, respectively. Surgery was considered as complete in 68 patients. Irradiation was normofractionated (NF) in 62 cases, hyperfractionated (BF) in 19 cases and hypofractionated (HF) in 8 cases. For all the patients, median delivered dose was 61 Gy [34-76 Gy]. RESULTS: Median follow-up of alive patients was 73,8 months [3-184]. Five-year local control (LC) and overall survival (OS) rates were 85.5 and 71.2% respectively. According to multifactorial analysis, favourable prognostic factors were for local control, complete surgery (P=0.0075) and for overall survival, complete surgery (P=0.0267), grade 1 tumor (P=0.012) and absence of distant recurrence (P=0.0488). There was no statistical evidence of difference for the five-year LC and OS rates between the patients who received NF, BF or HF. There were few complications and there were comparable in the three groups. CONCLUSIONS: This retrospective serie showed similar results for all the schedules. There is no evidence to recommend bifractionation. Hypofractionation should be used only in selected patients with poor performans status.

RESUMEN

The French legislation strictly controls the organization of assisted reproductive techniques (ART). The menopaused women are not allowed access to this kind of medical care. For women who still want to be pregnant, oocyte donation in a foreign country may offer a solution. The mortality and morbidity rates are higher for these women compared to the general population. We report two cases of pregnancy after oocyte donation in women around 45 years of age. The first one was complicated by preeclampsia and gestational diabetes. The second patient suffered from severe postpartum complications that needed intensive care during three weeks. The clinical consequences are discussed, together with legislative and ethical issues.

RESUMEN

Early premature rapture of the membranes (PROM) during pregnancy is associated with a high risk of perinatal morbidity and mortality. Early PROM impairs lung structures and function through 3 mechanisms : 1) oligo-hydramnios ; 2) fetal inflammatory syndrome ; and 3) prematurity. Thus, the related causes of respiratory failure at birth after PROM are: hyaline membrane disease, persistent pulmonary hypertension induced by impaired endothelial function and/or lung hypoplasia, materno-fetal infection, and bronchopulmonary dysplasia resulting at least in part from the fetal inflammatory syndrome. Severity of the respiratory morbidity is largely unpredictable. Even if gestational age at PROM is considered as a prognostic factor, survival without morbidity exist after PROM as early as 18 weeks GA. Better knowledge of the pathophysiology improved the outcome of the preterm infants born after early PROM. Optimal management of the respiratory failure including minimizing barotrauma is required to prevent from bronchopulmonary dysplasia.

RESUMEN

AIM: To measure ketonemia in a control population of pregnant women and in a population of women with gestational diabetes (GDM). To define a normal ketonemia threshold for the controls and to determine whether or not this value could play a role in the clinical management of women with GDM. METHOD: Fifty-six women with a normal OGTT and 49 women with GDM were included and monitored from the 25th to the 37th week of pregnancy. Control subjects agreed to perform glycaemia and ketonemia self-monitoring 3 times a day. In addition, women with GDM were asked to measure their postprandial glycaemia. Glycaemia and ketonemia measurements were performed using Optium meters. Subjects kept a 24-hour food record twice a week. RESULTS: The mean ketonemia was lower in the control group than in the GDM group (0.01+/-0.10 vs. 0.04+/-0.009 mmol/l; P<0.001). Ketonemia values measured before the midday meal and prior to the evening meal were lower for control subjects than for GDM patients (P=0.002 and P=0.005). Fasting ketonemia was unrelated to ketonuria in the GDM group, whereas there was a correlation in the control group (P=0.006). At least one chronic increase in ketonemia levels was observed in 47% of the women with GDM, compared with only 12% of controls. The lowest levels of evening glycaemia correlated with the highest levels of ketonemia; women with GDM reported lower food and carbohydrate intakes than controls (P<0.001). CONCLUSION: This work has enabled the establishment of ketonemia reference standards in non-diabetic pregnant women. If ketonemia does indeed indicate overly restrictive dietary behavior, this parameter could be employed for monitoring adherence to the nutritional recommendations for GDM.

RESUMEN

Q fever, a commonly reported zoonosis worldwide, is caused by infection with Coxiella burnetii, an obligate intracellular bacterium. The infection is often asymptomatic in ruminants, but it can lead to reproductive disorders with bacterial shedding into the environment. Between 2011 and 2013, a study was undertaken in small ruminant flocks in different regions of Algeria. A total of 35 flocks were visited and 227 sera and 267 genital swabs were collected from females after abortions or the lambing period to investigate Q fever infection. Indirect ELISA was used to detect specific antibodies against C. burnetii and real-time PCR for detecting bacterial DNA. Our survey indicated that 58% (95% CI=40-76%) of flocks had at least one positive animal (17 seropositive flocks) and individual seroprevalence was estimated at 14.1% (95% CI=11.8-16.4%) (32 seropositive animals). Bacterial excretion was observed in 21 flocks (60%), and 57 females showed evidence of C. burnetii shedding (21.3%). These results suggest that C. burnetii distribution is high at the flock level and that seropositive and infected (shedder) animals can be found all over the country. Further studies are needed in other regions and on different animal species to better understand the distribution and incidence of Q fever, as well as human exposure, and to develop an adequate prophylaxis program.

RESUMEN

We have conducted a phase I study with autologous monocytes activated ex vivo and administered intraperitoneally in nine patients with peritoneal carcinomatosis. Blood monocytes were collected by leukapheresis and then purified by counterflow elutriation (up to 10(9) cells, with a purity of greater than 90%). Ex vivo activation was obtained by incubating these cells with 1 micrograms liposomal MTP-PE/10(6) monocytes for 18 hours in hydrophobic culture bags at 37 degrees C in 5% carbon dioxide humidified air. The activated monocytes were then infused in the peritoneal cavity once a week for 5 consecutive weeks through an implanted peritoneal infusion system, Port-A-Cath (Pharmacia Deltec, St Paul, MN), on an intrapatient dose-escalating schedule (10(7) to 10(9) monocytes). No severe adverse reactions occurred. Toxicity was mild, the chief acute reactions being fever (27%), chills (13%), and abdominal pain (25%). None of the side effects led to dose reduction. No consistent change in hemostatic function, liver function, or renal function was observed. Significant increases in granulocyte counts, neopterine, and acute phase reactants (fibrinogen, C-reactive protein) occurred in the peripheral blood. In vitro monocyte activation was demonstrated by the relapse of procoagulant activity and monokines (interleukin-1 [IL-1], IL-6, and tumor necrosis factor-alpha [TNF alpha]) in the supernatants of cultured monocytes. Evidence for in vivo monocyte activation was provided by the increase of these monokines in the peritoneal fluids. Kinetic studies with indium-111 (111In)-labeled activated autologous monocytes in five patients suggest that these infused monocytes may remain in the peritoneal cavity for up to 7 days. This locoregional immunotherapeutic approach seems to be encouraging in view of adjuvant therapeutic modality in ovarian cancer patients with minimal residual intraabdominal disease following second-look laparotomy.

RESUMEN

High-dose cytarabine (HDARA-C) is an effective but toxic treatment for acute myeloid leukemia (AML). In order to reduce the incidence of severe complications noted with HDARA-C-containing regimens, we used a combination of intravenous (IV) idarubicin (IDARUB) at optimal dosage and cytarabine (ARA-C) at intermediate dosage. Thirty-five patients aged 23 to 78 years (median, 56) with AML in first relapse received IDARUB, 8 mg/m2/d for five days, and ARA-C, 1 g/m2 every 12 hours for six doses. Of the 35 patients, 21 achieved a complete remission (CR), four had a partial remission (PR), four died in aplasia, and six were nonresponders. The only factor influencing the CR rate was the duration of the first CR (35% for patients relapsing before 16 months v 83% for patients relapsing after 16 months, P = .003). Mucositis was the most significant extrahematologic side effect. Diarrhea, skin toxicity, and hepatic disturbances were rare and mild. There was no cerebellar toxicity, even in 25 patients greater than 50 years of age. This regimen is effective and well tolerated even in elderly patients, and could be used either as induction or consolidation therapy for the treatment of AML.

RESUMEN

In November 1987, the French group GOELAM initiated a randomized study comparing allogeneic bone marrow transplantation (BMT), autologous bone marrow transplantation (ABMT) and intensive consolidation chemotherapy (ICC). The induction treatment was randomized between Idarubicin plus Cytarabine and Zorubicine plus Cytarabine: 223 patients with de novo AML and aged 15-50 years are currently evaluable and 178 of them (80%) have achieved complete remission (CR) with no significant difference between both arms. Forty four patients under 40 years of age and having a HLA identical sibling were assigned to BMT and 38 were actually transplanted. Thirty of the 134 other patients did not receive the planned first course of ICC, 4 patients died during this course, and 21 were excluded before randomisation. Thus, only 64 patients have currently been randomized between the 2nd course of ICC (34 patients) and ABMT (30 patients). ABMT was prepared by the Baltimore regimen and the marrow was unpurged. With a median follow-up time of 29 months, the actuarial risk of relapse at 3 years is 29% for BMT, 38% for ABMT and 53% for ICC. The 3 year disease free survival (DFS) is 51% for BMT, 62% for ABMT and 47% for ICC. These differences are not statistically significant. When intention to treat is considered, there is no difference in the actuarial DFS between the BMT and the non BMT groups. Longer follow-up time and larger number of patients are warranted to demonstrate any significant advantage of one of these approaches.
