Purpose: Rare cancers represent 22% of all tumors in Europe; however, the quality of the data of rare cancers may not be as good as the quality of data for common cancer. The project surveillance of rare cancers in Europe (RARECARE) had, among others, the objectve of assessing rare cancer data quality in populaton-based cancer registries (CRs). Eight rare cancers were considered: mesothelioma, liver angiosarcoma, sarcomas, tumors of oral cavity, CNS tumors, germ cell tumors, leukemia, and malignant digestve endocrine tumors. Methods: We selected data on 18,000 diagnoses and revised, on the basis of the pathologic and clinical reports (but not on pathologic specimens), unspecified morphology and topography codes originally atributed by CR officers and checked the quality of follow-up of long-term survivors of poor prognosis cancers. Results: A total of 38 CRs contributed from 13 European countries. The majority of unspecified morphology and topography cases were confirmed as unspecified. The few unspecified cases that, after the review, changed to a more specific diagnosis increased the incidence of the common cancer histotypes. For example, 11% of the oral cavity epithelial cancers were reclassified from unspecified to more specific diagnoses: 8% were reclassified as squamous cell carcinoma (commoner) and only 1% as adenocarcinoma (rarer). The revision confirmed the majority of long-term survivors revealing a relatve high proporton of mesothelioma long-term survivors. The majority of appendix carcinoids changed behavior from malignant to borderline lesions. Conclusions: Our study suggests that the problem of poorly specified morphology and topography cases is mainly one of difficulty in reaching a precise diagnosis. The awareness of the importance of data quality for rare cancers should increase among registrars, pathologists, and clinicians. © 2016 Wichtg Publishing.

The present paper describes a case of shoe contact dermatitis from DMF identified by the Poison Control Centre of Milan (PCCM), Italy, in 2009. A 35 year old woman was affected by irritant reactions while wearing shoes contaminated with DMF. Exposure to these shoes was limited to a 8 hour period and was not repeated. In the following days the patient suffered feet blistering and swelling limited to the area in contact with shoe vamp. Topical application of cortisone did not prevent development of bullous eczema. After 20 days from exposure, the lesions were healed but the skin remained red, dry and very sensitive. Chemical analyses of shoes quantified an average concentration of DMF of 383 mg/kg. The patient refused to be patch tested. The observation here reported confirm that DMF should be considered a possible causal agent in shoe contact dermatitis. Documentation of cases exposed to this chemical provide a relevant support to characterize clinical manifestations and to identifying contaminated articles.

mAbs | Year: 2013

Monoclonal antibodies (mAb) have become a mainstay in tumor therapy. Clinical responses to mAb therapy, however, are far from optimal, with many patients presenting native or acquired resistance or suboptimal responses to a mAb therapy. MAbs exert antitumor activity through different mechanisms of action and we propose here a classification of these mechanisms. in many cases mAbs need to interact with immune cells to exert antitumor activity. We summarize evidence showing that interactions between mAbs and immune cells may be inadequate for optimal antitumor activity. This may be due to insufficient tumor accumulation of mAbs or immune cells, or to low-affinity interactions between these components. The possibilities to improve tumor accumulation of mAbs and immune cells, and to improve the affinity of the interactions between these components are reviewed. We also discuss future directions of research that might further improve the therapeutic efficacy of antitumor mAbs. © 2013 Landes Bioscience.


Observational outcome studies represent a valid approach to evaluating comparative treatment effectiveness in real populations. The main objective of outcome research is to underline what works and what does not work in the field of health assistance. In 2004 the Italian Ministry of Health launched the Project "Mattone Misura dell'Outcome" aimed at assessing the introduction of procedures and methods for the systematic evaluation of outcomes in the national health system. A new experience, the PROGRESSI program (PROGRamma ESiti per SIVeAS e LEA), started in 2008 with the aim to further develop the methodologies for outcome evaluation. In this Supplement the final results from four clinical studies named "Sperimentazioni dell'area cardiovascolare del Progetto Mattoni" are presented. These studies started between 2005 and 2007 and their main objectives were to evaluate: --the contribution of information from current informative systems and clinical studies in risk-adjustment methodologies; --the advisability of introducing some clinical items in current informative systems to improve outcome estimates; --the goodness of follow-up procedures from current informative systems; and --the role of disease registries in the validation of comparative evaluation measures. The four studies were designed as voluntary prospective multicentre studies. Results concerning the characteristics of the enrolled populations as well as the risk-adjustment models built using information from current informative systems and/or clinical information are presented. As expected, each study produced specific remarks both in terms of clinical findings and contribution of different informative systems to the risk-adjustment models. In general, models built with information from both current informative systems and clinical information show the best performance. Findings from these analyses will provide the public health system with suitable indications to improve statistical methodologies for outcome estimates.
