Our results strongly suggest that in early breast cancer patients with SN micrometastasis, selective SN lymphadenectomy suffices to control locoregional and distant disease, with no significant effects on survival.
Circumscribed to endemic areas throughout tropical countries, filariasis is a rare and unknown disease in Europe. We report four cases of calcified filariasis involving the breast, supporting the diagnosis on the typical mammographic appearance of the calcified worms and the past history of filarial infection. Few reports have been published in the radiology literature about this infrequent manifestation of the parasitation. The purpose of this article is to show the mammographic characteristics of this disease that soon will be seen frequently in developed countries due to the increasing population from the endemic areas.
Our objective was to evaluate our experience with the Advanced Breast Biopsy Instrumentation system (ABBI) in non-palpable breast lesions in a prospective study from July 1998 to November 2000. The ABBI system was included in a protocol for BIRADS 4 non-palpable, small (<15 mm) breast lesions. Digital radiographs of both specimen and biopsy cavity were obtained to validate the procedure. A total of 255 ABBI biopsies were performed in 254 patients. In 251 cases the lesions were successfully removed (98.4%). Mammographic lesions consisted of 176 cases of microcalcifications (69%), 51 cases of architectural distortions (20%) and 28 cases of nodules (11%). Seventy-two carcinomas were diagnosed (28.2%). Affected margins were found in 41 cases (56.9%). Residual tumour was seen in 31 patients (43%). Seventeen borderline results and 33 benign architectural distortions obviated further procedures. The complication rate in 10 cases was as follows: 3 wound infections; 4 haematomas; and 3 vasovagal reactions. The main utility of the ABBI system is to allow a reliable diagnosis in complex lesions, such as small clusters of microcalcifications and especially architectural distortions. Surgery can be avoided for borderline cases if the lesion is completely removed and free margins are obtained in the pathology study. Therapeutic use is controversial and can be applied only in selected cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
