Women's decision making about mammography: a replication of the relationship between stages of adoption and decisional balance.

Abstract: The motivational and cognitive processes of behavior change in the area of screening mammography were investigated. A total of 676 women, 40 to 79 years old, were recruited for telephone interview through random selection from designated census tracts and were asked questions that assessed mammography stage-of-adoption and decisional balance constructs from the trans-theoretical model of behavior change. Two definitions of stage of adoption were used. Analysis of covariance showed that a history of regular screening and an intention to continue having the exam were associated with a more favorable decisional balance. Results replicated a prior investigation and demonstrated the usefulness of stage of adoption and decisional balance as guides for designing stage-matched interventions to increase rates of mammography.

US of mammographically detected clustered microcalcifications.

Abstract: PURPOSE: To determine whether ultrasonography (US) can depict breast masses associated with mammographically detected clustered microcalcifications and whether the visibility at US is different between benign and malignant lesions. MATERIALS AND METHODS: Ninety-four patients with 100 mammographically detected microcalcification clusters prospectively underwent US with a 10- or 12-MHz transducer before mammographically guided presurgical hook-wire localization. The visibility of breast masses at US was correlated with histologic and mammographic findings. RESULTS: Surgical biopsy revealed 62 benign lesions, 30 intraductal cancers, and eight invasive cancers. At US, breast masses associated with microcalcifications were seen in 45 (45%) of 100 cases. US depicted more breast masses associated with malignant (31 [82%] of 38) than with benign (14 [23%] of 62) microcalcifications (P < .001). In malignant microcalcification clusters larger than 10 mm, US depicted associated breast masses in all 25 cases. There w...

Real-time ultrasound, axillary mammography, and clinical examination in the detection of axillary lymph node metastases in breast cancer patients.

Abstract: The axillary node status is important in the prognosis of breast cancer. To evaluate the accuracy of various preoperative examination methods in detecting metastatic axillary lymph nodes, we compared the findings of clinical examination, axillary ultrasonography, and axillary mammography of 41 breast cancer patients who underwent axillary dissection and histological examination. The sensitivity was 72.7% for ultrasonography, 38.9% for axillary mammography, and 32.3% for clinical examination. Ultrasonography provides good information about the axillary nodal status. The specificity can be increased by fine-needle biopsy under ultrasound guidance.

Full-field digital versus screen-film mammography: comparative accuracy in concurrent screening cohorts.

Abstract: OBJECTIVE. The purpose of this study was to compare the diagnostic accuracy of digital mammography with that of screen-film mammography in concurrent cohorts participating in the same population-based screening program.MATERIALS AND METHODS. In a retrospective study covering 2004–2005, we compared digital with screen-film mammography in two concurrent screening cohorts of women 50–69 years old participating in a screening program operated from mobile units. Each cohort had 14,385 participants matched by age and interpreting radiologist from all participants consecutively registered. We compared recall and cancer detection rates.RESULTS. The recall rate was higher for digital mammography (4.56% vs 3.96%, p =0.01), particularly when clustered microcalcifications were the only finding (1.05% vs 0.41%, p =10–6) and for younger women (50–59 vs 60–69 years, 5.12% vs 4.17%, p = 0.009). The higher recall rate for digital mammography was mainly evident at incidence screening. The recall rate due to poor technical ...

Diffuse optical measurement of blood flow in breast tumors

Abstract: Blood flow contrast between tumor and normal tissues in patients with malignant and benign breast cancer was measured by diffuse optical correlation methods. The measurements were carried out with a hand-held optical probe that was manually scanned over the tumor-bearing breast. Increased blood flow was observed in tumor regions relative to healthy tissue, and control subjects did not exhibit significant blood flow heterogeneity. The measurements introduce a new optical contrast for diffuse optical mammography.
