ABSTRACT
The present paper describes our experience of 47 cases of atypical ductal hyperplasia (ADH) diagnosed at vacuum-assisted biopsy. From June 1999 to December 2003, 47 consecutive diagnoses of non-palpable ADH of the breast were made by 11-gauge vacuum-assisted biopsy (Mammotome). Of these, 17 were subjected to surgical excision and 11 underwent a second Mammotome at the site of the previous vacuum-assisted biopsy. Diagnostic underestimation occurred in only two cases, with a surgical diagnosis of ductal carcinoma in situ. In both patients, aged between 46 and 55 years, the radiological images showed microcalcifications of >20 mm, and the lesions were not completely removed by Mammotome. Despite the obvious limitations of the present study, it can be concluded that the probability of underestimating ADH diagnosis by Mammotome appears to be related to the radiological features of the lesion (>20 mm) and to the adequacy of specimens.

The Authors report their experiences on the treatment of 13 consecutive cases of gastro-intestinal carcinoid tumors observed over the last 11 years. The primary sites were as follows: intestine (5 cases), appendix (3 cases), colon (1 case) and peritoneum (4 cases); only 3 patients presented systemic signs. Ten patients in advanced phase were treated with a chemotherapeutic regimen containing 5-fluorouracil (5-Fu) and streptozotocin (STZ). One case was excluded from the study because of a concomitant gastric carcinoma. Of the 9 evaluable patients, two achieved partial remission (22%) with a duration of 18+ and 66 months respectively; 4 (44.5%) had stable disease for periods ranging from 7 to 40 months and 3 cases progressed. Severe toxicity (thrombocytopenia and diarrhea) occurred in 2 cases and disappeared with the suspension of therapy. The systemic signs disappeared with treatment and did not appear in 2 cases out of 3. The prospective of the employment of new drugs such as alpha-interferon and, above all, somatostatin provides hope that this uncommon disease may have an improved response rate to treatment in the future.
