ABSTRACT Ductal lavage (DL) has been proposed as a minimally-invasive, well-tolerated tool for obtaining breast epithelial cells for cytological evaluation of breast cancer risk. We report DL tolerability in BRCA1/2 mutation-positive and -negative women from an IRB-approved research study.
165 BRCA1/2 mutation-positive, 26 mutation-negative and 3 mutation unknown women underwent mammography, breast MRI and DL. Psychological well-being and perceptions of pain were obtained before and after DL, and compared with pain experienced during other screening procedures.
The average anticipated and experienced discomfort rating for DL, 47 and 48 (0-100), were significantly higher (p < 0.01) than the anticipated and experienced discomfort of mammogram (38 and 34), MRI (36 and 25) or nipple aspiration (42 and 27). Women with greater pre-existing emotional distress experienced more DL-related discomfort than they anticipated. Women reporting DL-related pain as worse than expected were nearly three times more likely to refuse subsequent DL than those reporting it as the same or better than expected. Twenty-five percent of participants refused repeat DL at first annual follow-up.
DL was anticipated to be and experienced as more uncomfortable than other procedures used in breast cancer screening. Higher underlying psychological distress was associated with decreased DL tolerability.

    ABSTRACT: Elevated mammographic density (MD) is one of the strongest risk factors for sporadic breast cancer. Epidemiologic evidence suggests that MD is, in part, genetically determined; however, the relationship between MD and BRCA1/2 mutation status is equivocal. We compared MD in unaffected BRCA1/2 mutation carriers enrolled in the U.S. National Cancer Institute's Clinical Genetics Branch's Breast Imaging Study (n = 143) with women at low-to-average breast cancer risk enrolled in the same study (n = 29) or the NCI/National Naval Medical Center's Susceptibility to Breast Cancer Study (n = 90). The latter were BRCA mutation-negative members of mutation-positive families or women with no prior breast cancer, a Pedigree Assessment Tool score <8 (i.e., low risk of a hereditary breast cancer syndrome) and a Gail score <1.67. A single experienced mammographer measured MD using a computer-assisted thresholding method. We collected standard breast cancer risk factor information in both studies. Unadjusted mean percent MD was higher in women with BRCA1/2 mutations compared with women at low-to-average breast cancer risk (37.3% vs. 33.4%; P = 0.04), but these differences disappeared after adjusting for age and body mass index (34.9% vs. 36.3%; P = 0.43). We explored age at menarche, nulliparity, age at first birth, menopausal status, number of breast biopsies, and exposure to exogenous hormonal agents as potential confounders of the MD and BRCA1/2 association. Taking these factors into account did not significantly alter the results of the age/body mass index-adjusted analysis. Our results do not provide support for an independent effect of BRCA1/2 mutation status on mammographic density.

    ABSTRACT: to evaluate painful sensitivity and factors involved in producing papillary fluid suitable for cytological analysis by means of automated collection. we selected 50 asymptomatic women without a personal or family history of breast cancer, outside the pregnancy and childbirth cycle in order to collect papillary fluid by the automated system. We recorded and related to the production of papillary fluid patient age, smoking habit, previous breast surgery, parity, breastfeeding, menopausal status and age at menarche. All material collected was fixed in appropriate place, and sent separately for cytological analysis. The painful sensitivity of the collection procedure was assessed using the Borg Category-Ratio Scale (CR10 Scale). patient age ranged from 22 to 59 years, mean 41.6 ± 8.6 years. Of the 50 patients, 20 (40%) showed no papillary fluid suitable for analysis in the breasts. In those patients from whom appropriate fluid was obtained for analysis of papillary cytology, parity was inversely related to the ability to obtain suitable cell samples with a level of statistical significance of p=0.035, OR=0.0032 (95%CI=0.0001-0.1388). Regarding soreness, the exam was well tolerated. the automated method of fluid collection for analysis of papillary cytology was well tolerated by the women; thus producing analyzable material in 60% of cases, a rate was inversely related to parity.

    ABSTRACT: The study was designed to determine which histological lesions produce cellular atypia in lavage specimens and whether ductoscopy adds useful information for the evaluation of high-risk patients with atypical lavage cytology. We prospectively recruited women ≥35 years at high risk for developing breast cancer. All underwent ductal lavage. Women found to have atypia underwent ductoscopy-directed duct excision (group 1). Women without atypia were observed (group 2). Data included patient demographics, risk assessment, cytologic and histologic findings, and outcomes. Descriptive statistics were utilized for data summary and were compared using Fisher's exact test. We enrolled 102 women; 93 (91%) were Caucasian. Their median age was 49 (range 34-73) years with a median follow-up of 80 (range 5-90) months. Overall, 27 (26%) had atypical lavage cytology (group 1), and 75 (74%) had benign cytology (group 2). Subsequent duct excision in group 1 revealed benign histology in 11 (44%), papillomas in 9 (36%), atypical hyperplasia (AH) in 4 (16%), and ductal carcinoma in situ (DCIS) in 1 (4%). At follow-up, three patients developed breast cancer, including one group 1 patient and two group 2 patients. There were no differences between groups 1 and 2 according to patient demographics, Gail scores, or risk for subsequent breast cancer (P > 0.05). Although 20% of high-risk women with ductal lavage atypia have AH or malignancy on subsequent excision, the majority do not. Atypia identified by ductal lavage is not associated with a higher risk of developing subsequent breast cancer, even in this high-risk population.
