L'avenir de l'Organisation Commune de Marché des fruits et légumes: existe t-il un consentement entre les spécialistes?
[EN] The aim of this article was to identify the main factors that favour and limit the strengthening of producer organizations (POs) in the fruit and vegetables sector, as well as farmers’ adherence to these organizations and the future prospects with a view to the objectives set by the Common Market Organization (CMO) for 2013. The study was based on a Delphi-type questionnaire, applied in two rounds between April and July 2009. The most important results indicated the limited scope of the policies adopted under the CMO in fruit and vegetables and the weakness of the Fruit and Vegetables POs as regards the supply concentration (i.e. the volume traded through these organizations), a prerequisite to increase their bargaining power within the value chain. the single payment scheme, the operational funds and the crisis management funds will still be implemented beyond 2013 as a tool to support this sector.[FR] L’objectif de cet article était d’identifier les facteurs qui favorisent et ceux qui

A logistic model for the detection of circulating tumour cells in human metastatic colorectal cancer
The accuracy in the diagnosis of metastatic colorectal cancer (mCRC) represents one of the challenges in the clinical management of patients. The detection of circulating tumour cells (CTC) is becoming a promising alternative to current detection techniques, as it focuses on one of the players of the metastatic disease and it should provide with more specific and sensitive detection rates. Here, we describe an improved method of detection of CTC from mCRC patients by combining immune-enrichment, optimal purification of RNA from very low cell numbers, and the selection of accurate PCR probes. As a result, we obtained a logistic model that combines GAPDH and VIL1 normalized to CD45 rendering powerful results in the detection of CTC from mCRC patients (AUROC value 0.8599). We further demonstrated the utility of this model at the clinical setting, as a reliable prognosis tool to determine progression-free survival in mCRC patients. Overall, we developed a strategy that ameliorates the specificity and sensitivity in the detection of CTC, resulting in a robust and promising logistic model for the clinical management of metastatic colorectal cancer patients.Ministerio de Sanidad, Consumo y Bienestar Social.

Usefulness of bone turnover markers as predictors of mortality risk, disease progression and skeletal-related events appearance in patients with prostate cancer with bone metastases following treatment with zoledronic acid: TUGAMO study
Owing to the limited validity of clinical data on the treatment of prostate cancer (PCa) and bone metastases,
biochemical markers are a promising tool for predicting survival, disease progression and skeletal-related events (SREs) in these
patients. The aim of this study was to evaluate the predictive capacity of biochemical markers of bone turnover for mortality risk,
disease progression and SREs in patients with PCa and bone metastases undergoing treatment with zoledronic acid (ZA).
Methods: This was an observational, prospective and multicenter study in which ninety-eight patients were included. Patients
were treated with ZA (4mg every 4 weeks for 18 months). Data were collected at baseline and 3, 6, 9, 12, 15 and 18 months after
the beginning of treatment. Serum levels of bone alkaline phosphtase (BALP), aminoterminal propeptide of procollagen type I
(P1NP) and beta-isomer of carboxiterminal telopeptide of collagen I (b-CTX) were analysed at all points in the study. Data on
disease progression, SREs development and survival were recorded.
Results: Cox regression models with clinical data and bone markers showed that the levels of the three markers studied were
predictive of survival time, with b-CTX being especially powerful, in which a lack of normalisation in visit 1 (3 months after the
beginning of treatment) showed a 6.3-times more risk for death than in normalised patients. Levels of these markers were also
predictive for SREs, although in this case BALP and P1NP proved to be better predictors. We did not find any relationship
between bone markers and disease progression.
Conclusion: In patients with PCa and bone metastases treated with ZA, b-CTX and P1NP can be considered suitable predictors for
mortality risk, while BALP and P1NP are appropriate for SREs. The levels of these biomarkers 3 months after the beginning of
treatment are especially importantThis study was supported by Novartis Oncology Spai
Niraparib in patients with metastatic castration-resistant prostate cancer and DNA repair gene defects (GALAHAD): a multicentre, open-label, phase 2 trial
Background
Metastatic castration-resistant prostate cancers are enriched for DNA repair gene defects (DRDs) that can be susceptible to synthetic lethality through inhibition of PARP proteins. We evaluated the anti-tumour activity and safety of the PARP inhibitor niraparib in patients with metastatic castration-resistant prostate cancers and DRDs who progressed on previous treatment with an androgen signalling inhibitor and a taxane.
Methods
In this multicentre, open-label, single-arm, phase 2 study, patients aged at least 18 years with histologically confirmed metastatic castration-resistant prostate cancer (mixed histology accepted, with the exception of the small cell pure phenotype) and DRDs (assessed in blood, tumour tissue, or saliva), with progression on a previous next-generation androgen signalling inhibitor and a taxane per Response Evaluation Criteria in Solid Tumors 1.1 or Prostate Cancer Working Group 3 criteria and an Eastern Cooperative Oncology Group performance status of 0–2, were eligible. Enrolled patients received niraparib 300 mg orally once daily until treatment discontinuation, death, or study termination. For the final study analysis, all patients who received at least one dose of study drug were included in the safety analysis population; patients with germline pathogenic or somatic biallelic pathogenic alterations in BRCA1 or BRCA2 (BRCA cohort) or biallelic alterations in other prespecified DRDs (non-BRCA cohort) were included in the efficacy analysis population. The primary endpoint was objective response rate in patients with BRCA alterations and measurable disease (measurable BRCA cohort). This study is registered with ClinicalTrials.gov, NCT02854436.
Findings
Between Sept 28, 2016, and June 26, 2020, 289 patients were enrolled, of whom 182 (63%) had received three or more systemic therapies for prostate cancer. 223 (77%) of 289 patients were included in the overall efficacy analysis population, which included BRCA (n=142) and non-BRCA (n=81) cohorts. At final analysis, with a median follow-up of 10·0 months (IQR 6·6–13·3), the objective response rate in the measurable BRCA cohort (n=76) was 34·2% (95% CI 23·7–46·0). In the safety analysis population, the most common treatment-emergent adverse events of any grade were nausea (169 [58%] of 289), anaemia (156 [54%]), and vomiting (111 [38%]); the most common grade 3 or worse events were haematological (anaemia in 95 [33%] of 289; thrombocytopenia in 47 [16%]; and neutropenia in 28 [10%]). Of 134 (46%) of 289 patients with at least one serious treatment-emergent adverse event, the most common were also haematological (thrombocytopenia in 17 [6%] and anaemia in 13 [4%]). Two adverse events with fatal outcome (one patient with urosepsis in the BRCA cohort and one patient with sepsis in the non-BRCA cohort) were deemed possibly related to niraparib treatment.
Interpretation
Niraparib is tolerable and shows anti-tumour activity in heavily pretreated patients with metastatic castration-resistant prostate cancer and DRDs, particularly in those with BRCA alterations

Le secteur Espagnol de fruits et légumes et la politique agricole commune: actualité et perspectives dans le cadre de l’organisation commune de marchés
El sector de frutas y hortalizas es uno de los más importantes tanto en la agricultura europea como en la española. Actualmente está en vigor la Organización Común de Mercados (OCM), instrumento fundamental de regulación de los mercados agrarios y que constituye el primer pilar de la Política
Agraria Común. La más reciente reforma de la OCM -ocurrida en 2007- persigue mejorar la competitividad y la orientación al mercado del sector, así como promover el consumo, reforzar la protección medioambiental, incorporar la gestión de crisis y reducir la carga administrativa. Su adopción permitirá -en última instancia- aumentar la concentración de la oferta, lo que teóricamente se traduciría en mayor poder de negociación y, consecuentemente, en mejores
precios e ingresos percibidos por este eslabón de la cadena de valor. En este escenario, a partir de fuentes secundarias de información y de una encuesta Delphi, el presente estudio tiene por objetivos: i) identificar algunos rasgos distintivos del mercado de frutas y hortalizas frescas, tanto a nivel mundial como de la Unión Europea; ii) describir el marco legal y normativo que regula el funcionamiento del sector, especialmente su OCM, las

Identification of an ideal test environment for asparagus evaluation by GGE-biplot analysis
Abstract Asparagus is a perennial crop which remains in production for at least 10 years. Therefore, the appropriate election of cultivars is crucial for asparagus growers. The aim of this work was to determine which environment is most desirable for enhancing asparagus clonal hybrids selection. Thirty four asparagus clonal hybrids and two testers were planted in a complete randomized block design. Total yield was evaluated for each hybrid in four environments conformed by combinations between age of culture and type of production. Data were subjected to an ANOVA and broad sense heritability was calculated for each environment. GGE biplot methodology was also used. The second productive season (for blanched and green production) was the best test environment and the most powerful to discriminate genotypes. Selection in this productive season would reduce time and costs in asparagus cultivars evaluation
