Randomized Trial Comparing Cyclophosphamide, Methotrexate, and 5-Fluorouracil (CMF) Regimen with Rotational CMFEV Regimen (E=Epirubicin, V=Vincristine) as Adjuvant Chemotherapy in Moderate Risk Operable Breast Carcinoma

Objectives: The CMFEV (cyclophosphamide, methotrexate, 5-fluorouracil, epirubicin, vincristine) regimen is an innovative schedule, designed by our Group, aimed at administering five partially or totally no cross-resistant cytotoxic agents in breast carcinoma. It was randomly compared to CMF (cyclophosphamide, methotrexate, 5-fluorouracil) as primary treatment in operable disease and demonstrated a short-term significant increase in clinical complete response rate and a long-term significant locoregional relapse-free survival in premenopausal patients. So, it seemed worth comparing this regimen with CMF as adjuvant chemotherapy in moderate risk operable breast carcinoma. Methods: Four hundred and eighty-nine patients with stage I or II moderate risk breast carcinoma were randomized to receive CMF or CMFEV regimen for 6 cycles after surgery. Main end points were overall survival (OS), invasive disease-free survival (IDFS) and recurrence-free interval (RFI), as estimated by Kaplan-Meier analyses and log-rank tests. Results: At a median observation time of 7.3 years (range 5.4 months-10.3 years), no significant differences in OS and IDFS were observed between the two arms. Deaths from breast carcinoma were more frequent with CMF (58.5%) than with CMFEV regimen (41.7%) as well as recurrences from breast carcinoma (58.8% with CMF and 41.2% with CMFEV). These differences were not statistically significant. Conclusion: CMFEV appears more effective than CMF in preventing recurrences from primary disease in patients with moderate risk stage I-II breast carcinoma. The lack of statistical significance of the observed differences was probably due to the limited number of patients enrolled which rendered the study underpowdered.

Asthma severity in childhood and metabolomic profiling of breath condensate

世界最新医学信息文摘 2014年第7期 3-3页

Background Asthma is a heterogeneous disease and its different phenotypes need to be better characterized from a biochemical-inflammatory standpoint. This study aimed to apply the metabolomic approach to exhaled breath condensate (breathomics) to discriminate different asthma phenotypes, with a particular focus on severe asthma in *** In this cross-sectional study, we recruited 42 asthmatic children (age, 8–17 years): 31 with nonsevere asthma (treated with inhaled steroids or not) and 11 with severe asthma. Fifteen healthy children were enrolled as controls. Children performed exhaled nitric oxide measurement, spirometry, exhaled breath condensate (EBC) collection. Condensate samples were analyzed using a metabolomic approach based on mass *** A robust Bidirectional-Orthogonal Projections to Latent Structures-Discriminant Analysis (O2PLS-DA) model was found for discriminating both between severe asthma cases and healthy controls (R2 = 0.93; Q2 = 0.75) and between severe asthma and nonsevere asthma (R2 = 0.84; Q2 = 0.47). The metabolomic data analysis leads to a robust model also when the 3 groups of children were considered altogether (K = 0.80), indicating that each group is characterized by a specific metabolomic profile. Compounds related to retinoic acid, adenosine and vitamin D (Human Metabolome Database) were relevant for the discrimination between *** The metabolomic profiling of EBC could clearly distinguish different biochemical-metabolic profiles in asthmatic children and enabled the severe asthma phenotype to be fully discriminated. The breathomics approach may therefore be suitable for discriminating between different asthma metabolic phenotypes.
