The Cavitron ultrasonic surgical aspirator causes localised ultrasonic tissue fragmentation and has recently been used to remove intracranial tumours. We have examined tissue fragments from 17 operations in which the apparatus was used: in all cases a definitive diagnosis could be made from the material aspirated.

The reactive changes in the axillary lymph nodes of 50 breast cancer patients treated by mastectomy immediately following frozen section diagnosis have been compared with the changes in the nodes of 50 patients whose biopsy preceded mastectomy by between 2 and 5 days. The frequency of sinus histiocytosis was significantly greater in those patients who had been subjected to previous biopsy. This finding suggests that prior breast biopsy may negate the prognostic significance of sinus histiocytosis in breast cancer.
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.
