ABSTRACT

BACKGROUND: The epidermal growth factor receptor (EGFR) signaling system is frequently unbalanced in human malignancies due to increased ligand production, receptor overexpression, receptor mutations, and/or cross-talk with other receptor systems. For this reason, the EGFR is an attractive target for anticancer therapy. The epidermal growth factor also plays an important role in regulating multiple facets of cutaneous wound healing, including inflammation, wound contraction, proliferation, migration, and angiogenesis. In the Center of Molecular Immunology, a cancer vaccine is produced (CIMAvax® EGF) that blocks the binding of EGF to its receptor. This blockade causes a significant inverse association between the anti-EGF antibody titers and EGF concentration. Around 1,500 patients with non-small cell lung cancer have been treated, showing that this vaccine is safe, immunogenic, increases survival and improves quality of life. Taking into account the therapeutic benefits of CIMAvax® EGF vaccination and the role of EGF-EGFR system in the wound healing process, we decided to conduct a retrospective research with the aim of determining the effect to the CIMAvax® EGF vaccine on the wound healing process in patients undergoing surgical treatment. METHODS: Medical records of 452 vaccinated patients were reviewed and only six patients receiving surgical treatment were identified. Further information about these six patients was obtained from source documents, including medical records and operative reports using an observational list that included different variables. Post-surgical wound healing complications were identified using the National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI-CTC) version 3.0. RESULTS: None of the six patients operated on presented adverse events related to the wound healing, that is to say, no wound dehiscence, wound infection, delayed wound healing, fistula formation, abscess formation or hemorrhage/bleeding associated with surgery during treatment with CIMAvax® EGF occurred. CONCLUSIONS: These results suggest that the use of CIMAvax® EGF does not produce a deleterious effect in the wound healing process.

ABSTRACT

El cáncer constituye un serio problema de salud para la humanidad. La mayoría de los tumores primarios del Sistema Nervioso Central son tumores astrocíticos. En esta revisión se provee información sobre algunos aspectos relacionados con los tumores astrocíticos, que incluyen la clasificación, factores pronóstico, tratamiento habitual, terapia biológica y factores angiogénicos. El glioblastoma multiforme se diagnostica en los pacientes con una mayor frecuencia. El tratamiento estándar en pacientes con tumores astrocíticos comprende la cirugía, seguida de radiación y quimioterapia. Sin embargo, cada vez son más importantes las investigaciones dirigidas a la inmunoterapia y terapia génica como parte de las opciones terapéuticas en estos pacientes(AU)


Cancer is a serious health problem around the world. The majority of primary tumors of the Central Nervous System are of astrocytic lineage. In this review we provide an overview of several aspects related to this type of tumor, that includes classification, prognostic factors, therapy, and angiogenic factors. Glioblastoma Multiforme is diagnosed in patients at a much higher frequency. Standard treatment for patients with astrocytic tumors is surgery followed by radiotherapy and chemotherapy. However, immunotherapy and gene therapy studies are increasing to become other therapeutic options in these patients(AU)

ABSTRACT

El proceso de enseñanza-aprendizaje en el área de la Estadística experimenta una mejoría con las prácticas en los sistemas estadísticos. En algunas ocasiones las carreras universitarias que incluyen asignaturas relacionadas con la Estadística no tienen concebido en su Plan de Estudios prácticas con sistemas Estadísticos, y en otros, estas no son suficientes para desarrollar las habilidades prácticas que requiere esta disciplina. De modo general, las limitaciones materiales condicionan la ausencia total o parcial de actividades prácticas. El creciente desarrollo de las Tecnologías de la Información y la Comunicación (TIC) ha brindado la posibilidad de suplir estas carencias, con el desarrollo de Multimedias Interactivas y Aulas Virtuales. Este proyecto incluye un conjunto de Prácticas de Estadística en soporte Multimedia, que tienen como objetivo preparar al estudiante para obtener el máximo rendimiento en los sistemas estadísticos. Este producto puede ser utilizado como sustituto del Aula real en aquellos casos en que por razones de tiempo, espacio, la práctica real no sea posible(AU)


The process of teaching and learning quality in the area of statistics is determined largely by the good clinical practices. Sometimes university courses that include subjects related to Statistics are not viewed in its practical curriculum statistical system, and in others, these are not sufficient to develop the practical skills required for this discipline. In general, the material constraints condition the total or partial absence of practical activities. The increasing development of Information Technology and Communication (ICT) has provided the possibility of filling these gaps, with the development of Interactive Multimedia and Virtual Classrooms. This project includes a set of Practice of Statistics in multimedia, which aim to prepare the student to obtain maximum performance in statistical systems. This product can be used as a substitute for real classroom in those cases where for reasons of time, space, actual practice is not possible(AU)

ABSTRACT

El Centro de Inmunología Molecular ha venido desarrollando biomoléculas para el tratamiento del cáncer. En la medida que se avanza en el desarrollo de estos productos, se avanza en las fases I, II, III y IV de los ensayos clínicos, lo que trae aparejado un incremento en el número de pacientes a tratar y en el número de hospitales involucrados. Se cuenta con diez productos diferentes, implicados en más de 50 ensayos clínicos, nacionales y multinacionales, con un pronóstico de inclusión de 2 500 pacientes nuevos por año. En este proceso están incluidos alrededor de 30 hospitales en 13 provincias del país. Para mejorar el acceso a la información de ensayos clínicos por parte de los investigadores comprometidos, se creó un sitio Web formado por cuatro secciones fundamentales, relacionadas con los productos y sus indicaciones, buenas prácticas clínicas, la entrada remota de datos y la gerencia de los ensayos clínicos. Todo lo anterior mejora fundamentalmente la calidad de la información brindada a los investigadores clínicos involucrados y redunda en una mayor organización de la compleja actividad de los ensayos clínicos en Cuba


The Molecular Immunology Center has been developing biomolecules for cancer treatment. As the development of such products continues, phases I, II, III and IV of clinical assays also advance, which leads to an increase of the number of patients to be treated and the number of involved hospitals. There are ten different products involved in over 50 national and multinational clinical assays in which 2 500 patients are predicted to be included every year. Approximately 30 hospitals from 13 provinces are included in this process. For the purpose of improving the access of committed researchers to the clinical assay information, a new Website with four sections was devised. Those sections are related to products and their indications, good clinical practice, remote data entry and clinical assay management. All the above-mentioned improves the quality of the information given to involved clinical researchers and results in better organization of the complex activity of clinical assays in Cuba
