RESUMEN

BACKGROUND: Oxaliplatin, a major drug in metastatic colorectal cancer (mCRC), is responsible for cumulative, dose-limiting peripheral neuropathy (PN). Whether the hepatic arterial infusion (HAI) route can limit oxaliplatin-induced PN in comparison with the intravenous (IV) route has not been specifically explored so far. METHODS: We compared the frequency and severity of PN in oxaliplatin-naive patients with mCRC included in trials that evaluated treatment with oxaliplatin administered either by HAI (ACCORD 04, CHOICE, OSCAR, and PACHA-01 trials) or by IV route (FFCD 2000-05 trial). We retrieved anonymized, prospectively collected data from trial databases for the ACCORD 04, CHOICE, and FFCD 2000-05 trials and through a review of Gustave Roussy patients' electronic medical records for PACHA-01 and OSCAR trials. The primary endpoint was the incidence of clinically significant PN (grades 2 to 4) according to the cumulative dose of oxaliplatin received. Secondary endpoints were time to onset of neuropathy as a function of the cumulative dose of oxaliplatin, discontinuation of oxaliplatin for neurotoxicity, and safety. RESULTS: A total of 363 patients were included (IV, 300; HAI, 63). In total, 180 patients in the IV group (60%) and 30 patients in the HAI group (48%) developed clinically significant PN, with no significant difference between the two groups (p = 0.23). No difference was shown in the time to onset of PN either (p = 0.23). CONCLUSION: The administration of oxaliplatin HAI rather than IV in the treatment of mCRC does not reduce the incidence, precocity, and severity of PN.

RESUMEN

PURPOSE: Previous cohort studies have reported plasma TK1 activity (pTKa) as a potential prognostic biomarker in estrogen receptor-positive (ER+) HER2-negative (HER2-) metastatic breast cancer (MBC). In this prospective study, we report here the prognostic impact of pTKa in ER+/HER2- MBC patients treated with endocrine therapy and CDK4/6 inhibitor. EXPERIMENTAL DESIGN: Patients were included into the prospective, ethics committee-approved ALCINA study (NCT02866149). Eligibility criteria were patients with ER+/HER2- MBC treated at Institut Curie with endocrine therapy and palbociclib. Plasma samples were obtained at baseline and after 4 weeks of treatment. pTKa was quantified by the DiviTum® assay (Biovica, Sweden). RESULTS: From May 2016 to August 2018, 103 patients treated with endocrine therapy and palbociclib were included. Patients had received a median of two prior systemic therapies for MBC (range 0-14). Median follow-up was 13.8 months (range 6-31), with median PFS and OS of 9.6 months (95%CI [7.0-11.3]) and 28 months (95%CI [23-not reached]), respectively. Median baseline pTKa was 292 Du/L (range 20-27,312 Du/L, IQR [89-853]). After adjusting for other prognostic factors, baseline pTKa remained an independent prognostic factor for both PFS (HR = 1.3 95%CI [1.1-1.4], p = 0.0005) and OS (HR = 1.3 95%CI [1.2-1.6], p < 0.0001), and 4-week pTKa was associated with OS (HR = 1.6 95%CI [1.3-2], p < 0.0001). That survival prediction was significantly improved by the addition of baseline pTKa to clinicopathological characteristics. Adding pTKa changes at 4 weeks to baseline pTKa did not further increase survival prediction. CONCLUSION: This study demonstrates the clinical validity of pTKa as a new circulating prognostic marker in ER+/HER2- MBC patients treated with endocrine therapy and palbociclib.

RESUMEN

BACKGROUND: Proof of concept studies has reported that circulating endothelial cell (CEC) count may be associated with the outcome of HER2-negative metastatic breast cancer (mBC) patients treated by chemotherapy and the anti-VEGF antibody bevacizumab. We report the results obtained in an independent prospective validation cohort (COMET study, NCT01745757). METHODS: The main baseline criteria were HER2-negative mBC, performance status 0-2 and no prior chemotherapy for metastatic disease. CECs were detected by CellSearch® from 4 ml of blood at baseline and after 4 weeks of weekly paclitaxel and bevacizumab therapy. CEC counts (considered both as a continuous variable and using the previously described 20 CEC/4 ml cutoff) were associated with clinical characteristics and progression-free survival (PFS). RESULTS: CEC count was obtained in 251 patients at baseline and in 207 patients at 4 weeks. Median baseline CEC count was 22 CEC/4 ml (range 0-2231). Baseline CEC counts were associated with performance status (p = 0.02). No statistically significant change in CEC counts was observed between baseline and 4 weeks of therapy. High baseline CEC count was associated with shorter PFS in univariate and multivariate analyses (continuous: p < 0.001; dichotomized: HR 1.52, 95% CI [1.15-2.02], p = 0.004). CEC counts at 4 weeks had no prognostic impact. CONCLUSION: This study confirms that CEC count may be associated with the outcome of mBC patients treated with chemotherapy and bevacizumab. However, discrepancies with previous reports in terms of both the timing of CEC count and the direction of the prognostic impact warrant further clinical investigation.

RESUMEN

BACKGROUND: Microsatellite instability (MSI) has recently emerged as a predictive pan-tumor biomarker of immunotherapy efficacy, stimulating the development of diagnostic tools compatible with large-scale screening of patients. In this context, noninvasive detection of MSI from circulating tumor DNA stands as a promising diagnostic and posttreatment monitoring tool. METHODS: We developed drop-off droplet-digital PCR (ddPCR) assays targeting BAT-26, activin A receptor type 2A (ACVR2A), and defensin beta 105A/B (DEFB105A/B) microsatellite markers. Performances of the assays were measured on reconstitution experiments of various mutant allelic fractions, on 185 tumor samples with known MSI status, and on 72 blood samples collected from 42 patients with advanced colorectal or endometrial cancers before and/or during therapy. RESULTS: The 3 ddPCR assays reached analytical sensitivity <0.1% variant allelic frequency and could reliably detect and quantify MSI in both tumor and body fluid samples. High concordance between MSI status determination by the three-marker ddPCR test and the reference pentaplex method were observed (100% for colorectal tumors and 93% for other tumor types). Moreover, the 3 assays showed correlations with r ≥ 0.99 with other circulating tumor DNA markers and their dynamic during treatment correlated well with clinical response. CONCLUSIONS: This innovative approach for MSI detection provides a noninvasive, cost-effective, and fast diagnostic tool, well suited for large-scale screening of patients that may benefit from immunotherapy agents, as well as for monitoring treatment responses.

RESUMEN

BACKGROUND: The long-term survival of germline retinoblastoma patients is decreased due to the risk of second primary tumors (SPTs) that occur years after the diagnosis of retinoblastoma. This risk is related to genetic predisposition and other factors, such as the treatment of retinoblastoma by external beam radiotherapy (EBRT). PROCEDURE: We studied the incidence, risk factors, and prognosis of specific craniofacial SPTs developed within the margins of radiation field in a cohort of 209 patients with germline retinoblastoma treated with EBRT at our institution between 1977 and 2010. Clinical characteristics, survival, incidence, and histology of craniofacial SPTs were recorded. RESULTS: Fifty-three of the 209 patients developed 60 distinct craniofacial SPTs in irradiated field with a median time from EBRT of 16.9 years (4-35) and a median follow-up of 24.8 years (5.3-40). Osteosarcoma (33.3%) and undifferentiated sarcoma (23.3%) were the more prevalent histological entities. Benign tumors (16.7%) also occurred. The cumulative incidence of craniofacial SPTs reached 32.6% at 35 years after EBRT, and the median survival after diagnosis was five years. In our series, irradiation under 12 months of age, bilateral EBRT, or previous treatment of retinoblastoma with chemotherapy did not significantly increase the risk of craniofacial SPTs. CONCLUSIONS: This work presents a strong argument to avoid EBRT in the management of retinoblastoma and emphasizes the high risk and poor prognosis of specific craniofacial SPTs. This study also points to the question of the need and benefits of special programs for early detection of craniofacial SPTs in survivors of irradiated germline retinoblastoma.

RESUMEN

BACKGROUND: 1p/19q-codeleted anaplastic gliomas have variable clinical behavior. We have recently shown that the common 9p21.3 allelic loss is an independent prognostic factor in this tumor type. The aim of this study is to identify less frequent genomic copy number variations (CNVs) with clinical importance that may shed light on molecular oncogenesis of this tumor type. MATERIALS AND METHODS: A cohort of 197 patients with anaplastic oligodendroglioma was collected as part of the French POLA network. Clinical, pathological, and molecular information was recorded. CNV analysis was performed using single-nucleotide polymorphism arrays. Computational biology and feature selection based on the random forests method were used to identify CNV events associated with overall survival and other clinical-pathological variables. RESULTS: Recurrent chromosomal events were identified in chromosomes 4, 9, and 11. Forty-six focal amplification events and 22 focal deletion events were identified. Twenty-four focal CNV areas were associated with survival, and five of them were significantly associated with survival after multivariable analysis. Nine out of 24 CNV events were validated using an external cohort of The Cancer Genome Atlas. Five of the validated events contain a cancer-related gene or microRNA: CDKN2A deletion, SS18L1 amplification, RHOA/MIR191 copy-neutral loss of heterozygosity, FGFR3 amplification, and ARNT amplification. The CNV profile contributes to better survival prediction compared with clinical-based risk assessment. CONCLUSION: Several recurrent CNV events, detected in anaplastic oligodendroglioma, enable better survival prediction. More importantly, they help in identifying potential genes for understanding oncogenesis and for personalized therapy. IMPLICATIONS FOR PRACTICE: Genomic analysis of 197 anaplastic oligodendroglioma tumors reveals recurrent somatic copy number variation areas that may help in understanding oncogenesis and target identification for precision medicine. A machine learning multivariable model built using this genomic information enables better survival prediction.

RESUMEN

LESSONS LEARNED: Results suggest that the combination of bevacizumab plus temozolomide is active in terms of response rate, survival, performance, quality of life, and cognition in elderly patients with glioblastoma multiforme with poor performance status.Whether this combination is superior to temozolomide alone remains to be demonstrated by a randomized study. BACKGROUND: The optimal treatment of glioblastoma multiforme (GBM) in patients aged ≥70 years with a Karnofsky performance status (KPS) <70 is not established. This clinical trial evaluated the efficacy and safety of upfront temozolomide (TMZ) and bevacizumab (Bev) in patients aged ≥70 years and a KPS <70. MATERIALS AND METHODS: Patients aged ≥70 years with a KPS <70 and biopsy-proven GBM were eligible for this multicenter, prospective, nonrandomized, phase II trial of older patients with impaired performance status. Treatment consisted of TMZ administered at 130-150 mg/m2 per day for 5 days every 4 weeks plus Bev administered at 10 mg/kg every 2 weeks. RESULTS: The trial included 66 patients (median age of 76 years; median KPS of 60). The median overall survival (OS) was 23.9 weeks (95% confidence interval [CI], 19-27.6), and the median progression-free survival (PFS) was 15.3 weeks (95% CI, 12.9-19.3). Twenty-two (33%) patients became transiently capable of self-care (i.e., KPS >70). Cognition and quality of life significantly improved over time during treatment. Grade ≥3 hematological adverse events occurred in 13 (20%) patients, high blood pressure in 16 (24%), venous thromboembolism in 3 (4.5%), cerebral hemorrhage in 2 (3%), and intestinal perforation in 2 (3%). CONCLUSION: This study suggests that TMZ + Bev treatment is active in elderly patients with GBM with low KPS and has an acceptable tolerance level.

RESUMEN

We present new and complete growth charts for 2,598 healthy French children and adolescents with Down syndrome (DS) from 0 to 20 years old, obtained with highly reliable statistical methods. This study is retrospective and addresses data collected over a period of 12 years, monocentric and with a satisfactory representation of the population nationwide. Final occipito-frontal circumference (OFC) is at the fifth percentile compared to WHO charts, with a drop between 12 and 18 months. Final height is at the first percentile compared to WHO charts for girls and boys with two periods of reduced growth velocity: before 36 months and around puberty. We observed no pubertal growth peak for girls. For boys, pubertal growth peak showed to happen earlier and to be less significant than in the general population. When compared to a previous French study with people affected with DS, pubertal growth acceleration begins at a later age for girls and boys; girls in our study are taller at age 15 (+5 cm), but there is no difference for boys at this age. Overweight is more frequent compared to the typical French population. Mean body mass index (BMI) rises rapidly above the 75th percentile of typical French children as early as age 4, with an earlier age for precocious adiposity rebound. The second period for rapid increase of BMI is around 14 years old. When compared to a previous French study with DS, we did not observe any BMI increase, at least up to the age of 14.

RESUMEN

The objectives of this study were to obtain updated neonatal measurements in French newborns with Down Syndrome (DS) according to their gestational age, and to assess the frequency and distribution of congenital anomalies. Data on congenital malformations, birth weight, birth length and birth occipito-frontal circumference (OFC) according to the gestational age was gathered from 1,030 babies, born between 1980 and 2010. The mean gestational age was 38 weeks from the date of the last menstrual period (LMP) (range: 29-42 weeks). Repartition of complications was found to be similar to previous studies, with no difference according to the date of birth. For girls born after 37 weeks, the mean birth weight was 3,012 ± 430 g, the mean birth length was 47.7 ± 2 cm, and the mean birth OFC was 33 ± 1.4 cm. For boys born after 37 weeks, the mean birth weight was 3,103 ± 459, the mean birth length was 48.4 ± 2.2 cm, and the mean birth OFC was 33.2 ± 1.4 cm. We did not find any difference in these measurements when we compared children born before 1997 and after 2007. When compared to the general population (French data and WHO charts), newborns with DS have a more pronounced difference in their birth length and their birth OFC (15-25th) than in their birth weight (25-50th). The shape of the growth curves shows that growth velocity decreases during the last weeks of gestation in all measurements, which suggests that the modal age for delivery could be earlier in DS newborns than in the general population.

RESUMEN

OBJECTIVES: Despite awareness of negative health outcomes associated with smoking, pregnant smokers might reduce their tobacco consumption thinking that a low smoking rate reduces smoking-related negative birth outcomes. We aimed to assess in a clinical sample whether there is a smoking rate that would not impact on birth weight (BW). METHODS: Pregnant smokers ≥18 years, gestational age of 9-20 weeks of amenorrhea, motivated to quit smoking, smoking ≥5 cigarettes/day (cpd) and their newborns (381 singleton, live births) were included in this secondary analysis of a French smoking cessation trial. RESULTS: The mean BW when the mother quit smoking was 3417 g (95 % CI: 3098-3738 g); when smoking >0<5 cpd, 3081g (3003-3159 g); when smoking 5-9 cpd, 3043 g (2930-3157 g); and when smoking ≥10 cpd, 2831 g (2596-3157 g) (p = .006). The corresponding effect sizes ranged from medium to large (Cohen's d for BW: 0.54, 0.57 and 0.85) compared to BW when the mother quit. In the multivariable analysis, adjusted for all significant confounders, when the mother smoked on average >0<5 cpd, the loss in BW was 228 g; when smoking 5-9 cpd, 251 g; and when smoking ≥10 cpd, 262 g (all p ≤ .02) compared to newborns' BW of mothers who stopped smoking since quit date. CONCLUSIONS: Even low cigarette consumption during pregnancy is associated with BW loss. All efforts should be made to help pregnant smokers quit completely during their pregnancy. IMPLICATIONS: As an alternative to quitting smoking, pregnant smokers reduce their smoking rate thinking that this diminishes smoking-related negative health outcomes. No study has established whether low smoking rate (more than 0 but less than 5 cpd) during pregnancy impacts BW compared to abstinence from smoking. Among treatment-seeking pregnant smokers BW of newborns of mothers who smoked even less than 5 cpd was significantly lower than of those whose mothers quit; effect sizes of different consumption levels on BW ranged from moderate (>0<5 cpd) to large (≥10 cpd). Even low smoking rate is associated with reduced BW compared to complete maternal smoking abstinence.

RESUMEN

BACKGROUND: Repetitive transcranial magnetic stimulation has been explored in patients with obsessive-compulsive disorder, but with negative or conflicting results. This randomized double-blind study was designed to assess the efficacy of 1-Hz repetitive transcranial magnetic stimulation over the presupplementary area. METHODS: Forty medication-resistant patients were assigned to 4 weeks of either active or sham repetitive transcranial magnetic stimulation targeting the presupplementary area with the help of a neuronavigation system. RESULTS: According to the Yale-Brown obsessive-compulsive scale, the baseline-week 4 evolution showed no significant differences between groups. Responder rates at week 4 were not different between groups (repetitive transcranial magnetic stimulation 10.5% vs sham 20%; P=.63). CONCLUSION: Low-frequency repetitive transcranial magnetic stimulation applied to the presupplementary area seems ineffective for the treatment of obsessive-compulsive disorder patients, at least in severe and drug-refractory cases such as those included in this study. Further research is required to determine profiles of responder patients and appropriate repetitive transcranial magnetic stimulation parameters for obsessive-compulsive disorder.

RESUMEN

BACKGROUND: Internet-based interventions targeted at the most at-risk gamblers could reduce the treatment gap for addictive disorders. Currently, no clinical trial has included non-treatment-seeking patients who have been recruited directly in their gambling environment. This study was the first exclusively Internet-based randomized controlled trial among non-help-seeking problem gamblers with naturalistic recruitment in their gambling environment. OBJECTIVE: The aim of this study was to assess the efficacy of three modalities of Internet-based psychotherapies with or without guidance, compared to a control condition, among problem gamblers who play online poker. METHODS: All active poker gamblers on the Winamax website were systematically offered screening. All problem poker gamblers identified with a Problem Gambling Severity Index (PGSI) score of ≥ 5 were eligible to be included in the trial. Problem gamblers were randomized into four groups: (1) waiting list (control group), (2) personalized normalized feedback on their gambling status by email, (3) an email containing a self-help book to be downloaded with a Cognitive Behavioral Therapy (CBT) program without guidance, and (4) the same CBT program emailed weekly by a trained psychologist with personalized guidance. Efficacy was assessed based on the change in PGSI between baseline and 6 weeks (end of treatment) or 12 weeks (maintenance) and supported by player account-based gambling data automatically collected at the three time points. RESULTS: All groups met high attrition rates (83%), but the group with guidance had a significantly higher dropout rate than the other three groups, including the control group. Although all groups showed some improvement, with a mean decrease of 1.35 on the PGSI, no significant difference in efficacy between the groups was observed. One-third of the problem gamblers fell below the problem gambling threshold at 6 weeks. CONCLUSIONS: Guidance could have aversively affected problem gamblers who had not sought help. Despite the lack of significant difference in efficacy between groups, this naturalistic trial provides a basis for the development of future Internet-based trials in individuals with gambling disorders. Comorbidities, natural course of illness, and intrinsic motivation seem to be critical issues to consider in future designs. TRIAL REGISTRATION: ANSM 2013-A00794-41.

RESUMEN

Amyotrophic lateral sclerosis is a typically rapidly progressive neurodegenerative disorder affecting motor neurons leading to progressive muscle paralysis and death, usually from respiratory failure, in 3-5 years. Some patients have slow disease progression and prolonged survival, but the underlying mechanisms remain poorly understood. Riluzole, the only approved treatment, only modestly prolongs survival and has no effect on muscle function. In the early phase of the disease, motor neuron loss is initially compensated for by collateral reinnervation, but over time this compensation fails, leading to progressive muscle wasting. The crucial role of muscle histone deacetylase 4 and its regulator microRNA-206 in compensatory reinnervation and disease progression was recently suggested in a mouse model of amyotrophic lateral sclerosis (transgenic mice carrying human mutations in the superoxide dismutase gene). Here, we sought to investigate whether the microRNA-206-histone deacetylase 4 pathway plays a role in muscle compensatory reinnervation in patients with amyotrophic lateral sclerosis and thus contributes to disease outcome differences. We studied muscle reinnervation using high-resolution confocal imaging of neuromuscular junctions in muscle samples obtained from 11 patients with amyotrophic lateral sclerosis, including five long-term survivors. We showed that the proportion of reinnervated neuromuscular junctions was significantly higher in long-term survivors than in patients with rapidly progressive disease. We analysed the expression of muscle candidate genes involved in the reinnervation process and showed that histone deacetylase 4 upregulation was significantly greater in patients with rapidly progressive disease and was negatively correlated with the extent of muscle reinnervation and functional outcome. Conversely, the proposed regulator of histone deacetylase 4, microRNA-206, was upregulated in both patient groups, but did not correlate with disease progression or reinnervation. We conclude that muscle expression of histone deacetylase 4 may be a key factor for muscle reinnervation and disease progression in patients with amyotrophic lateral sclerosis. Specific histone deacetylase 4 inhibitors may then constitute a therapeutic approach to enhancing motor performance and slowing disease progression in amyotrophic lateral sclerosis.

RESUMEN

BACKGROUND: KRAS mutation is the most common molecular alteration in pancreatic adenocarcinoma (PDAC), and around 10% of patients harbor KRAS wild-type tumors (KRASWT). METHODS: A retrospective chart review of clinical/molecular data was performed including all PDAC patients with a determined KRAS status (tumor molecular profiling on tissue or liquid biopsy). RESULTS: 342 patients were included with 54 KRASWT PDAC (16%) compared to 288 patients with KRASm PDAC. Median age was 61 years [IQR:54.0;67.0] and 164 pts (48%) were female. At diagnosis, KRASWT patients (63%) were more frequently diagnosed at a non-metastatic stage compared to KRASm patients (41%) (p = 0.003). Regarding metastatic sites, liver was less frequent in KRASWT (39%, p < 0.0001). Median overall survival (mOS) from initial diagnosis was significantly higher in the KRASWT group compared to KRASm (50.8 months, CI95% [32.0-NR] vs 21.1 months, CI95% [18.9-23.4] (p < 0.004 after adjustment on age, ECOG and stage at diagnosis). In first-line systemic treatment, (mostly FOLFIRINOX) progression-free survival (PFS) was also higher in KRASWT. Based on ESCAT classification, a putative actionable alteration (ESCAT I-III) was identified in 19 (36%) KRASWT pts and 46 (16%) KRASm patients (p < 0.0001) with more alterations in FGFR2, BRAF(V600E), NRTK and more MSI tumors. KRASWT harbored also fewer alterations in TP53, CDKN2A, and SMAD4. 12 KRASWT patients received a molecularly-matched treatment with clinical benefit and improved outcomes compared to KRASm patients. CONCLUSIONS: KRASWT patients display distinct disease characteristics and outcomes with prolonged overall survival. KRASWT patients also harbor more actionable molecular alterations, leading to higher survival rates after receiving molecularly matched treatments.

RESUMEN

INTRODUCTION: Hydroxychloroquine (HCQ) is an important medication for treating systemic lupus erythematosus (SLE). Its blood concentration ([HCQ]) varies widely between patients and is a marker and predictor of SLE flares. This prospective randomised, double-blind, placebo-controlled, multicentre study sought to compare standard and adjusted HCQ dosing schedules that target [HCQ] ≥1000 ng/ml to reduce SLE flares. PATIENTS AND METHODS: [HCQ] was measured in 573 patients with SLE (stable disease and SELENA-SLEDAI≤12) treated with HCQ for at least 6 months. Patients with [HCQ] from 100 to 750 ng/ml were randomised to one of two treatment groups: no daily dose change (group 1) or increased HCQ dose to achieve the target [HCQ] (group 2). The primary end point was the number of patients with flares during 7 months of follow-up. RESULTS: Overall, mean [HCQ] was 918±451 ng/ml. Active SLE was less prevalent in patients with higher [HCQ]. A total of 171 patients were randomised and followed for 7 months. SLE flare rates were similar in the two groups (25% in group 1 vs 27.6% in group 2; p=0.7), but a significant spontaneous increase in [HCQ] in both groups between inclusion and randomisation strongly suggested improved treatment adherence. Patients at the therapeutic target throughout follow-up tended to have fewer flares than those with low [HCQ] (20.5% vs 35.1%, p=0.12). CONCLUSIONS: Although low [HCQ] is associated with higher SLE activity, adapting the HCQ dose did not reduce SLE flares over a 7-month follow-up.

RESUMEN

OBJECTIVE: Subclinical inflammation and radiographic progression have been described in rheumatoid arthritis (RA) patients whose disease is in remission or is showing a low level of activity. The aim of this study was to compare the ability of ultrasonography and magnetic resonance imaging (MRI) to predict relapse and radiographic progression in these patients. METHODS: Patients with RA of short or intermediate duration that was either in remission or exhibiting low levels of activity according to the Disease Activity Score (DAS) were included in the study. Over a period of 1 year, patients underwent clinical and biologic assessments every 3 months and radiographic assessments at baseline and 12 months. Radiographs were graded according to the modified Sharp/van der Heijde score (SHS). At baseline, patients underwent ultrasonography and MRI, which were graded using binary and semiquantitative scoring systems. Relapse was defined as a DAS of ≥2.4, and radiographic progression was defined as an increase in the SHS of ≥1. We tested the association of values by multivariate logistic regression. RESULTS: A total of 85 RA patients with a mean disease duration of 35.3 months were studied. RA was in remission in 47 of these patients, and 38 had low levels of disease activity. At 1 year, 26 of the 85 patients (30.6%) showed disease relapse, and 9 of the 85 patients (10.6%) showed radiographic progression. The baseline PD synovitis count (i.e., the number of joints at baseline for which the power Doppler [PD] signal indicated synovitis) predicted relapse (adjusted odds ratio [OR] 6.3; 95% confidence interval [95% CI] 2.0-20.3), and the baseline PD synovitis grade predicted disease progression (adjusted OR 1.4 [95% CI 1.1-1.9]). MRI was not predictive of outcomes. CONCLUSION: For RA patients whose disease is in remission or who have low levels of disease activity, PD signals on ultrasonography could predict relapse or radiographic progression and identify those whose disease is adequately controlled, which is especially helpful when considering treatment tapering or interruption.

RESUMEN

We analysed the therapeutic outcomes of all consecutive patients with primary central nervous system lymphoma (PCNSL) registered in the prospective French database for PCNSL and treated with intensive chemotherapy (IC) followed by autologous stem cell transplantation (IC-ASCT) between 2011 and November 2019 (271 patients recruited, 266 analysed). In addition, treatment-related complications of thiotepa-based IC-ASCT were analysed from the source files of 85 patients from 3 centers. Patients had received IC-ASCT either in first-line treatment (n = 147) or at relapse (n = 119). The median age at IC-ASCT was 57 years (range: 22-74). IC consisted of thiotepa-BCNU (n = 64), thiotepa-busulfan (n = 24), BCNU-etoposide-cytarabine-melphalan (BEAM, n = 36) and thiotepa-busulfan-cyclophosphamide (n = 142). In multivariate analysis, BEAM and ASCT beyond the first relapse were adverse prognostic factors for relapse risk. The risk of treatment-related mortality was higher for ASCT performed beyond the first relapse and seemed higher for thiotepa-busulfan-cyclophosphamide. Thiotepa-BCNU tends to result in a higher relapse rate than thiotepa-busulfan-cyclophosphamide and thiotepa-busulfan. This study confirms the role of IC-ASCT in first-line treatment and at first-relapse PCNSL (5-year overall survival rates of 80 and 50%, respectively). The benefit/risk ratio of thiotepa-busulfan/thiotepa-busulfan-cyclophosphamide-ASCT could be improved by considering ASCT earlier in the course of the disease and dose adjustment of the IC.
