Abstract

This study is the continuation and extension of a former investigation done by the author and proposes the use of trace elements in blood serum analyzed by PIXE and IC-MS to establish possible correlations for early diagnosis of melanoma. For comparison, it will also establish trace element reference levels for healthy patients, in a regular case control study. The structure of the serum components will be investigated to identify if the trace elements are free in solution or linked to proteins and/or molecules. Preparation of blood serum samples will be improved, by the addition of Low Temperature Ashing procedures, aiming to reduce the high organic load, which interferes with the trace element analysis, and consequently obtain the reduction of the already low detection limits. This study will be executed in collaboration, and with resources, from the Hospital do Câncer under the supervision of Dr. Mariangela Correa (protocols number 1000/07 from Hospital do Câncer and 20071109143330 from UNIFESP). This project may be associated to a possible future thematic interdisciplinary project "Multi-scale Analysis of Neoplasic Processes" currently under assessment.
