False-negative diagnoses at stereotactic vacuum-assisted needle breast biopsy: long-term follow-up of 1,280 lesions and review of the literature.

Objective: The purpose of this study was to determine retrospectively the frequency and causes of false-negative diagnoses of lesions evaluated with percutaneous stereotactic biopsy performed with vacuum-assisted probes with the patient prone on a biopsy table.

Materials And Methods: The records of 1,152 women (median age, 55 years; range, 31-94 years) with 1,280 lesions consecutively biopsied with 14-gauge (n = 159) or 11-gauge (n = 1,121) vacuum probes were reviewed retrospectively. The histologic diagnoses were malignant (n = 489), high-risk (n = 117), and benign (n = 674) lesions.

Stereotactic histologic biopsy with patients prone: technical feasibility in 98% of mammographically detected lesions.

Objective: The purpose of this retrospective study was to determine which mammographically detected lesions in need of imaging-guided biopsy could undergo prone, stereotactic biopsy.

Materials And Methods: From July 1991 through June 2001, 1687 consecutive patients (age range, 29-94 years; median age, 58 years) with 1894 lesions were referred by clinicians in a multispecialty clinic. The patients underwent stereotactic, prone, histologic biopsy of 1851 lesions (98%) and needle-localized breast biopsy of 43 lesions (2%).

Stereotactic, automated, large-core needle biopsy of nonpalpable breast lesions: false-negative and histologic underestimation rates after long-term follow-up.

Purpose: To determine the rate and causes of false-negative findings and histologic underestimates at stereotactic biopsy of nonpalpable breast lesions.

Materials And Methods: Stereotactic, 14-gauge, automated, large-core needle biopsy (LCNB) was performed in 483 consecutive nonpalpable breast lesions. Excision was advised for the 143 carcinomas, 25 atypical ductal hyperplasia (ADH) lesions, and five radial scars.

Percutaneous removal of benign mammographic lesions: comparison of automated large-core and directional vacuum-assisted stereotactic biopsy techniques.

Objective: The purpose of our study was to evaluate how often histologically benign lesions were completely removed as shown by the initial mammogram after biopsy. We compared three percutaneous biopsy techniques.

Materials And Methods: Retrospective review was performed on 1206 consecutive impalpable breast lesions having percutaneous stereotactic biopsies done on a prone biopsy table using 14-gauge automated large-core needles (n = 721); 14-gauge directional vacuum-assisted probes (n = 192); and 11-gauge directional vacuum-assisted probes (n = 293).

Needle-localized breast biopsy: why do we fail?

Purpose: To determine what factors are associated with unsuccessful needle-localized breast biopsy (NLBB).

Materials And Methods: Findings in 280 consecutive nonpalpable breast lesions in 262 women (age range, 27-87 years; mean age, 55 years) who underwent nonstereotactic, mammographically guided, standardized NLBB were retrospectively analyzed according to mammographic lesion type, lesion size, number of lesions per breast, needle type, proximity of needle to lesion, radiologist, specimen size, surgeon, and histologic findings.

Results: Biopsy failed in seven (2.

Stereotaxic large-core needle biopsy of 450 nonpalpable breast lesions with surgical correlation in lesions with cancer or atypical hyperplasia.

Purpose: To determine whether histologic findings of cancer or atypical hyperplasia at large-core needle biopsy (LCNB) of nonpalpable breast lesions match histologic findings at excision.

Materials And Methods: Stereotaxic LCNB was performed with an automated prone unit, biopsy gun, and 14-gauge cutting needles in 450 nonpalpable breast lesions. Lesions classified as carcinoma or atypical ductal hyperplasia (ADH) at histologic examination after LCNB were excised.

A 7 year experience with low anterior sigmoid resections using the EEA stapler.

The EEA stapler was used in 205 patients over a 7 year period with 19 complications (9 percent) and 1 death (0.5 percent). Meticulous attention to technique and familiarization with the EEA stapler are necessary to achieve such results.

Outpatient adult inguinal hernia repair.

Repair of adult inguinal hernia has been done on an outpatient basis at our surgical facility for the past six years. In 616 consecutive repairs, complications have been remarkably few: one patient was electively admitted to hospital, two hernias have recurred and one patient needed to be catheterized. Patient acceptance has been enthusiastic.

Impact of adjuvant chemotherapy on cosmesis and complications in stages I and II carcinoma of the breast treated by biopsy and radiation therapy.

Cosmesis and complication rates were examined in patients with early stage carcinoma of the breast treated by biopsy and radiation therapy with and without adjuvant chemotherapy in an attempt to determine the effect of chemotherapy upon these parameters. Between April 1, 1975 and June 1, 1980, 51 patients were treated with radiation therapy and adjuvant chemotherapy (XRT + ACT) and 83 patients with radiotherapy alone (XRT). Chemotherapy usually consisted of cytoxan, methotrexate and 5-fluorouracil for 6 or 12 cycles.

Bacteremia following cleft palate repair--a prospective study.

A prospective study of temperature patterns and blood cultures following cleft palate repair suggests that bacteremia in these cases is common. Twenty-seven years without serious complications supports the authors' view that antibiotic therapy is not indicated.

Biopsy and definitive radiation therapy in stages I and II carcinoma of the female breast.

One hundred-twenty patients with Stages I and II carcinoma of the female breast were treated by biopsy followed by definitive radiation therapy without mastectomy. The breast received 4500-5000 cGy (rad) using a 6 MV linear accelerator followed by a supplement to the area of the primary tumor of 2000 cGy (rad) using electrons in 99 patients (83%) and interstitial implantation in 21 patients (17%). Local recurrence was not recorded in the 43 patients with Stage I disease, while three of 77 patients (4%) with Stage II disease suffered a local recurrence.
