Peripheral T-cell lymphomas (PTCLs) are a group of nonHodgkin lymphomas (NHLs) with heterogeneous clinical presentation, histology, response to treatment and outcome, whose genetic background is still poorly understood. Patients with PTCL are usually treated with CHOP or more intensive regimens, generally with minimal effectiveness, thus highlighting the need for new therapeutic strategies.

Background: it is necessary to find serological markers accessible in clinical practice to prevent the need to perform repeated endoscopies.Objective: to assess the efficacy of eosinophil activity markers in monitoring eosinophilic esophagitis (EoE).Material and methods: thirty patients were included prospectively, all under dietary treatment -diets excluding 6 foods, and allergy test based diet (skin prick test and specific IgE). The variables assessed were demographic parameters, eosinophil cationic protein (ECP) levels (μg/mL), total IgE (KU/L), peripheral blood eosinophils (PBE) (U/mm 3 ), and the maximum peak of eosinophils/hpf in esophageal biopsies. The variation found between these figures was assessed in line with response to dietary treatment.Results: thirty patients (66.7 % males; mean age 33.43 years) were included in the study, 22 responders and 8 non-responders. Ninety percent presented a personal history of atopy. No significant decrease was detected in serum total IgE and ECP after diet in responder and nonresponders. However, the PBE decreased significantly in responders but not in nonresponders, PBE in responders (pre-diet. 397.27 vs. post-diet 276.81, p = 0.024) and non-responders PBE (pre-diet. 460 vs. post-diet 317.5, p = 0.23).Conclusion: serum total IgE and ECP do not act as markers for EoE activity. However PBE may play a role in this regard, bearing in mind that this parameter may be influenced by concomitant atopic conditions.

Predictive biomarkers of trabectedin represents an unmet need in advanced soft-tissue sarcomas (STS). DNA damage repair (DDR) genes, involved in homologous recombination or nucleotide excision repair, had been previously described as biomarkers of trabectedin resistance or sensitivity, respectively. The majority of these studies only focused on specific factors (ERCC1, ERCC5 and BRCA1) and did not evaluate several other DDR-related genes that could have a
