Detection of Benign and Malignant Thyroid and Breast Tumors by Fourier Transform Infrared Spectrometry

In operation patients, discriminant between benign and malignant thyroid and breast tumors are established by fourier transform infrared spectrometry variables, and pathologic diagnoses are gold standard.
Between Patients and healthy volunteers, discriminant are established among thyroid and breast tumors and healthy tissues.

Galectin 3 Dosage in Diagnosis of Nodular and Multinodular Goiter

Diagnosis Interest of Galectin 3 Dosage in Nodular and Multinodular Goiter Pretreatment

Se and Sp of plasmatic galectin 3 dosage will be established relative to the reference method which is the histological analysis of the specimen (report) asserting the existence of a vesicular lineage tumor, benign (adenoma) or malignant (papillary or follicular).
The threshold giving the best compromise for the values of Se and Sp will be searched graphically. Then the area under the curve and its confidence interval at 95% will be calculated and will be tested against the value 0.5, that is to say an area where the assay has no diagnostic value.
