a

This table summarizes the number of tumors detected before surgery by conventional check-up and those visualized by immunoscintigraphy (no tumor site was detected before surgery for patient n° 5).

b

P, physical examination, US, ultrasonography;CT-scan, tomodensitometry.

c

TP, true-positive; TN, true-negative; FP,false-positive; FN, false-negative; ND, not done.

d

Final diagnosis established on pathological examination of surgical samples or of biopsy specimen (patient 7, iliac bone; patient 11), or coelioscopy (patient 11), or selective venous catheterization (patient 7, neck).
