PurposeTo evaluate maximum tolerated dose and recommended dose (RD) for phase II studies of topotecan (TPT) combined with temozolomide (TMZ) (TOTEM) in children and adolescents with relapsed or refractory solid malignancies.Patients and methodsMulticentre, phase I study with a standard ‘3 + 3’ design in five dose increments. Eligible patients: aged 6 months to 21 years, diagnosis of a solid malignancy failed at least 2 previous lines of therapy. TMZ was administered orally, starting at 100 mg/m2/d, and TPT intravenously over 30 min, starting at 0.75 mg/m2/d over 5 consecutive days every 28 d. A pharmacokinetics analysis was performed on Day 1 and Day 5 of cycle 1.ResultsBetween February and October 2007, 16 patients were treated. The median age was 8.5 years (range, 3–19 years). Dose-limiting toxicity (grade 4 neutropenia and/or thrombocytopenia lasting more than 7 d) during the first cycle occurred in 2 of 3 patients at level 3 (TMZ 150 mg/m2/d and TPT 1.0 mg/m2/d) and was always manageable. Confirmed complete and partial responses were observed in 4 patients (25%), three with metastatic neuroblastoma and one with high-grade glioma. Seven patients had a stable disease. Pharmacokinetic data show a wide inter-individual variability. No significant differences were observed between plasma TMZ and TPT concentrations on Day 1 and Day 5 indicating the absence of pharmacokinetic interaction between the drugs.ConclusionsThe RD for the combination is TMZ 150 mg/m2/d and TPT 0.75 mg/m2/d with dose-limiting haematological toxicity. The observed activity deserves further evaluation in paediatric malignancies. 相似文献

Introduction
Typical medullary breast carcinoma (MBC) has recently been recognized to be part of the basal-like carcinoma spectrum, a feature in agreement with the high rate of TP53 mutations previously reported in MBCs. The present study was therefore designed to identify phenotypic and genetic alterations that distinguish MBCs from basal-like carcinomas (BLC).Methods
Expression levels of estrogen receptor (ER), progesterone receptor (PR), ERBB2, TP53, cytokeratins (KRTs) 5/6, 14, 8/18, epidermal growth factor receptor and KIT, as well as TP53 gene sequence and high-density array comparative genomic hybridization (CGH) profiles, were assessed and compared in a series of 33 MBCs and 26 BLCs.Results
All tumors were negative for ER, PR and ERBB2. KRTs 5/6 were more frequently expressed in MBCs (94%) than in BLCs (56%) (p = 0.0004). TP53 mutations were disclosed in 20/26 MBCs (77%) and 20/24 BLCs (83%). Array CGH analysis showed that a higher number of gains (95 regions) and losses (34 regions) was observed in MBCs than in BLCs (36 regions of gain; 13 regions of losses). In addition, gains of 1q and 8q, and losses of X were found to be common to the two groups, whereas gains of 10p (53% of the cases), 9p (30.8% of the cases) and 16q (25.8% of the cases), and losses of 4p (34.8% of the cases), and amplicons of 1q, 8p, 10p and 12p were the genetic alterations found to characterize MBC.Conclusion
Our study has revealed that MBCs are part of the basal-like group and share common genomic alterations with BLCs, the most frequent being 1q and 8q gains and X losses; however, MBCs are a distinct entity within the basal-like spectrum, characterized by a higher rate of KRT 5/6 expression, a higher rate of gains and losses than BLCs, recurrent 10p, 9p and 16q gains, 4p losses, and 1q, 8p, 10p and 12p amplicons. Our results thus contribute to a better understanding of the heterogeneity in basal-like breast tumors and provide potential diagnostic tools. 相似文献373.

Background
Forced vital capacity (FVC) remains difficult to determine for some patients suffering from amyotrophic lateral sclerosis (ALS) due to the rapid progression of the disease. Arterial blood gas (ABG) parameters could represent a valuable alternative. The aim of this study was therefore to evaluate the correlation between ABG parameters and FVC, along with the prognostic ability of ABG parameters, in a large cohort of ALS patients.Methods
ALS patients (n=302) with FVC and ABG parameters available at diagnosis were included. Correlations between ABG parameters and FVC were evaluated. Cox regression was then carried out to determine the association of each parameter (ABG and clinical data) with survival. Finally, receiver operating characteristic (ROC) curves were built to predict the survival of ALS.Results
Bicarbonates (HCO3−), oxygen partial pressure (pO2), carbon dioxide partial pressure (pCO2), base excess (BE), oxygen saturation and oxyhemoglobin were significantly correlated with FVC both in patients with spinal or bulbar onset. Univariate Cox regression showed that HCO3− and BE were associated with survival but only in spinal forms. ABG parameters predicted the survival of ALS with a similar performance to FVC, HCO3− being the parameter with the highest area under the curve.Conclusions
Our results suggest that there is an interest in conducting a longitudinal evaluation throughout disease progression to confirm the equal performances of FVC and ABG. This study highlights the benefits of performing ABG analysis that could be used as an interesting alternative to FVC when spirometry cannot be performed. 相似文献374.

Background
Tracheobronchial foreign body aspiration is a classic pediatric emergency, and its associated morbidity particularly depends on the anesthetic management, which differs according to the center and the practitioner.Aims
The aim of this study was to evaluate the different anesthetic practices for tracheobronchial foreign body extraction.Methods
A survey was sent via email to the member physicians of the Association des Anesthésistes Réanimateurs Pédiatriques d'Expression Française (ADARPEF). The survey included 28 questions about the organizational and anesthetic management of an evolving clinical case.Results
A total of 151 physicians responded to the survey. Only 13.2% of the respondents reported that their institution had a management protocol, and 21.7% required a computerized tomography scan before the procedure was performed for children who were asymptomatic or mildly symptomatic during the night. There were 56.3% of the respondents who reported that extraction with a rigid bronchoscope is the only procedure usually performed in their institution. Regarding rigid bronchoscopy, 47.0% used combined intravenous-inhalation anesthesia. The objective was to maintain the child on spontaneous ventilation for 63.6% of the respondents, but anesthesia management differed according to the physician's experience.Conclusions
Our study confirms the diversity of practices concerning anesthetic for tracheobronchial foreign body extraction and found reveal differences in practice according to physician experience. 相似文献375.
