Caini antrenati pentru diagnosticul cancerului

La congresul international de endocrinologie de la San Diego s-a prezentat un studiu in care cainele Frankie a fost folosit pentru a diagnostica pacientii cu cancer tiroidian.
Of 34 urine samples — 15 with PTC and 19 benign — Frankie's alert matched the final surgical pathology diagnosis in 30 out of 34 cases (88.2% accuracy, two false negatives and two false positives), yielding a sensitivity of 86.6%, specificity of 89.5%, a positive predictive value of 73.3%, and a negative predictive value of 95.3%.
The Kappa coefficient — which accounts for the amount of agreement that could be attributed to chance — was 0.75, indicating "good" agreement, Dr Bodenner said during the press briefing.

Nu e valabil doar pentru cancerul de tiroida.
Dragut, nu? Banuiesc ca metoda de diagnostic ar fi destul de dog-dependent, daca potaia nu e antrenata bine sau daca are o raceala, ai cam pus-o, dar… de ce nu? In plus, daca exista niste compusi volatili care se elimina prin urina si pe care cainele ii poate mirosi, eventual se pot si descoperi vreodata si astfel simplifica diagnosticul cancerului.
