Abstract
Intraoperative detection of colorectal carcinoma with the Neoprobe gamma detector has been useful in surgical decisionmaking regarding resectability by localizing additional tumor not readily identified by palpation or inspection, and in determining surgical resection margins. Tumor labeling has been achieved in 84% of the patients. Occult tumor has been identified in 18% of evaluable patients and changed operative decisions in 43% of patients. New monoclonal antibodies with radiolabels offer hope for more effective agents for imaging, Radioimmunoguided Surgery® and potential therapeutic modalities. Grâce aux anticorps monoclonaux marqués et le détecteur gamma Néoprobe, on a évalué la résecabilité et décelé des formations tumorales non palpables ou déterminé les marges de sécurité après résection des cancers colorectaux chez 84% de nos patients. Une tumeur occulte a été identifiée chez 18% des patients et a fait changer l'attitude thérapeutique chez 43% d'entre eux. L'utilisation des anticorps monoclonaux marqués offre des espoirs nouveaux dans 1'imagerie; la chirurgie radioguidée est une nouvelle voie de modalité thérapeutique. La exploración intraoperatoria con instrumentos como el detector gamma Neoprobe ha sido de utilidad en el proceso de decisión quirúrgica en relación a la resecabilidad, a la detección de tumor adicional no fácilmente detectable mediante la palpación y la inspección, y en la determinación de los márgenes quirúrgicos. La identificación del tumor ha sido posible en 84% de los pacientes. Tumor oculto ha sido detectado en 18% de los pacientes valorables y modificó las decisiones quirúrgicas en 43%. Los nuevos anticuerpos monoclonales radiomarcados ofrecen la esperanza de nuevas posibilidades para imagenología, cirugía radio-inmunodirigida y potenciales modalidades terapéuticas.Keywords
