BACKGROUND The study's aim was to identify technical factors that are predictive of negative margins after breast-conserving surgery (BCS). METHODS This was a retrospective, cohort study of patients who underwent BCS for early-stage cancer from 2000 to 2002. Pathological and specific surgical factors were compared with margin status. Univariate and(More)
BACKGROUND This systematic review examines whether radioguided localization surgery (RGL) (radioguided occult lesion localization - ROLL and radioguided seed localization - RSL) for non-palpable breast cancer lesions produces lower positive margin rates than standard wire-guided localization surgery. METHODS We performed a comprehensive literature review(More)
Elevated vasodilatory response (blushing) to social situations is characteristic of social phobia (SP). A relatively unexplored basis for this phenomenon is alteration in underlying vasodilatory mechanisms. To investigate this possibility, we evaluated the vasodilatory response induced by methyl nicotinate (niacin ester derivative) in 31 generalized SP(More)
BACKGROUND We surveyed Canadian General Surgeons to examine decision-making in early stage breast cancer. METHODS A modified Dillman Method was used for this mail survey of 1443 surgeons. Practice patterns and factors that influence management choices for: preoperative assessment, definition of margin status, surgical techniques and recommendations for(More)
BACKGROUND This study examined the impact of intraoperative digital specimen mammography (IDSM) compared with conventional specimen radiography (CSR) for nonpalpable breast lesions in patients undergoing breast-conserving surgery (BCS). METHODS In this retrospective cohort study, 201 consecutive image-detected nonpalpable breast lesions underwent BCS(More)
BACKGROUND For patients with breast cancer, a negative surgical margin at first breast-conserving surgery (BCS) minimizes the need for reoperation and likely reduces postoperative anxiety. We assessed technical factors, surgeon and hospital case volume and margin status after BCS in early-stage breast cancer. METHODS We performed a retrospective cohort(More)
Although breast conservation surgery (BCS) is commonly performed, several aspects of the procedure remain controversial. We undertook a cross-sectional survey to compare Canadian (CDN) and American (AM) general surgeons' reported BCS practice patterns to better understand the cross-border differences in early-stage breast cancer surgery care. A modified(More)
BACKGROUND The primary study objective was to compare the cosmetic result of radioguided seed localization (RSL) with wire localization (WL). METHODS A subgroup of patients enrolled in a multicentered, randomized trial comparing WL with RSL participated. Frontal photographs were taken 1 and 3 years postsurgery.
