The clinical-radiologic-cytologic triplet was used for diagnostic evaluation in 1708 women over 30 years old with a breast lump. All the lumps were subjected to surgery except for 258 cases in which clinical resolution took place within 1-2 months. Seven-hundred and ninety-three out of 1450 nodules removed were cancers. Sensitivity of the clinical, mammographic and cytologic examinations was 82%, 73% and 68%, respectively. It increased to 95% when they were as sociated. Specificity was 63%, 80% and 97%, respectively. The predictive value of positive results of the triple test was 100%. No patient with malignant cytology was subsequently shown to have benign disease. The systematic use of the triple test in solid breast lumps for the early detection of cancer is recommended as a routine procedure. However, participation of experienced radiologists and pathologists as well as physicians skilled in fine needle puncture is required.

Of about 8500 women with a minimum age of 30 years who had a breast examination at our Ouptatient Clinic from April 1982 to March 1983, we found in 286 cases a clinically evident carcinoma, and in 534 cases an apparently benign or suspect solid lump. All 534 of these cases were subjected to the triplet clinical, mammographic and cytologic diagnostic investigation by needle aspiration within 1 to 4 days. The clinical judgment was based on a method of scoring of the characters of 9 physical features (Clinical Diagnostic Index) in use at our Institute. The results of the examinations were grouped into 5 categories: 1) certain benignancy or negativity of the examination; 2) probable benignancy (excluding the cytologic examination); 3) probable malignancy; 4) certain malignancy; 5) nonevaluability of the examination (excluding the clinical examination). Except for 80 cases with collectively negative examinations which were clearly or completely regressed at the control within 2 months, all the others were subjected to surgery. On the basis of the histologic examination (or if regression occurred), 284 of the 534 lumps examined were found to be benign or nontumoral, whereas the other 250 (47%) were carcinomas. Of the latter, 57% were not more than 20 mm in size, whereas in 67.6% there was no microscopic evidence of axillary metastases. Sensitivity of the clinical, mammographic and cytologic examinations was 0.79, 0.76 and 0.72, respectively; specificity 0.71, 0.75 and 0.94, respectively, and the predictive value for malignancy of the positive response of the three examinations 0.71, 0.75 and 0.93, respectively. The use of the diagnostic triplet demonstrated an overall sensitivity of 0.95, specificity of 0.59, and a predictive value for malignancy of 0.98 and 0.93 for benignancy. These results confirm the usefulness of the systematic use of the diagnostic triplet in solid breast lumps of over thirty aged women for the early detection of cancer.

Sonography has become a helpful adjunct to mammography mainly for a differential diagnosis between simple cysts and solid masses. The authors examined by ultrasound 134 palpable masses in the breast which had been previously evaluated by clinical examination and mammography and then submitted to biopsy or fine needle aspiration. The exact diagnosis of a simple cyst was made in 94.1% of the cases, whereas the diagnosis of fibroadenoma was made in 80% of the cases. Ultrasound examination proved to be useful in patients with dense breasts: in this group, 82.1% of the patients with a histologic diagnosis of benign status had a correct ultrasound diagnosis. In agreement with other authors, we believe that breast sonography has no part in screening programs.
