Physical examination, mammography and fine-needle aspiration cytology were performed in 1498 consecutive cases with a solitary solid lump of the female breast. The intent was to verify the validity of this diagnostic triplet in the accuracy of the preoperative diagnosis of breast cancer. Clinically sure cancers were excluded from the study. The collected data were evaluated in terms of sensitivity, specificity and predictivity of any procedure alone or in combination. In 1138 cases confirmed by histology (514 carcinomas and 669 benign or non-neoplastic lesions), the physical examination and mammography were very sensitive (respectively 96% and 84%) but with a high rate of false-positive reports (respectively 20% and 18%). The cytologic diagnosis was less sensitive (65%), mostly due to many inadequate smears, but highly specific (93%) and predictive for malignancy (99%) when the cytologic report was frankly positive. Any single procedure improved the overall sensitivity, and taken together this triplet appears to be the most effective noninvasive diagnostic combination that provides in a short time with minimal cost and discomfort, a diagnosis of certain malignancy in about 50% of carcinomas with a predictivity close to 100%, when cytology detected malignancy.

We report our preliminary clinical experience with hematoporphyrin derivative (HpD) injection and argon or dye laser irradiation for the treatment of 61 surface neoplastic lesions in 7 patients. Forty-three sites were multiple basal cell carcinoma in 5 patients, and the remaining 18 were cutaneous and subcutaneous recurrent breast carcinoma after mastectomy in the thoracic wall. The patients were selected on the basis of the lack of indication for conventional therapeutic modalities. The selection of irradiation procedures and laser source was based on the thickness of the lesion and extension of the disease. The photochemical reaction between HpD injected i.v. at a dose of 3 mg/kg body weight and the laser beam at a dose of 60 to 120 J/cm2 resulted in 75% favorable responses at the treated sites. Optimal therapeutic effects appeared to be critically dependent on total light dose and tumor infiltration patterns. The phototherapeutic technique proved to be effective in selected cases of neoplastic lesions, especially when conventional treatment modalities were poorly indicated or contraindicated.

From June 1978 to December 1980 at the Istituto Nazionale Tumori of Milano, a fine-needle aspiration biopsy was performed on each of 4834 cases of palpable mammary nodules, the large majority of which were clinically and mammographically suspicious for cancer and only a small part clinically definitely positive. Of these, 1173 underwent surgery at this institution, and 534 (45.5%) had a histologically proven carcinoma. The aspirations were performed by individuals different from those who read the cytologic smears. The aspirations were never repeated, and methods for the retrieval of cells were never applied. Under the circumstances, sensitivity was 0.67, specificity 0.98, and the predictive value for positive results 0.97. The high percentage of inadequate samples (25.5%) influenced the low sensitivity. The few false-positive results occurred exclusively during the first year. Frozen sections can be avoided in those cases (about 50%) with definitely positive cytologic diagnosis by the application of strict criteria. The intrinsic incapability of cytology to yield any information on the extent and the invasiveness of a malignant lesion does not seem to effect its preoperatory conclusiveness.

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.

In the present study we report the long-term results for 120 female patients who underwent mastectomy for breast cancer, from 1955 to 1965, and in whom the first relapse was represented by a skin recurrence or a supraclavicular lymph node metastastis. Eighty-nine patients had been submitted only to local therapy, 11 had also undergone bilateral oophorectomy, and in the remaining 20 hormonal compounds had been administered in addition to local therapy. The disease-free interval between the first and the second relapse, and survival after the treatment of the first relapse were strictly related to the presence and the number of axillary lymph node metastases at the time of the mastectomy (N category). In fact, the median survival was 19.5 months for 63 cases with more than 3 metastatic lymph nodes, 29 months for 24 cases with 1–3 involved lymph nodes, and 59 months for 38 cases without axillary involvement. No significant difference in survival was observed in relation to chronological age and menopausal status of the patients or to the lenght of the disease-free interval. The association of endocrine therapies to local treatment of the recurrences also did not increase the survival rate in these cases. The present data indicate that the prognosis for patients with recurrent breast cancer is mainly related to the N category.
