Imaging-Guided Core Needle Biopsy of the Breast: Study of Psychological Outcomes

The objective of this study was to evaluate and document pain and psychological distress related to imaging-guided core needle biopsy (CNB) of the breast. This prospective study of 52 consecutive patients undergoing CNB of the breast assessed anxiety, pain, acute stress disorder, and activities of daily living both preprocedure and at 24 hours, 5 days, and 30 days postprocedure. Survey instruments included the State-Trait Anxiety Inventory (STAI), a visual analog pain scale, the SF-36 Physical Functioning Scale, and DSM IV criteria for acute stress disorder. Preprocedure the mean scores for self-reported levels of state and trait anxiety were 47.11 (SD = 13.53) and 37.71 (SD = 11.24), respectively. At 24 hours postprocedure, the mean score for self-reported state anxiety was 38.74 (SD = 17.77), a significant reduction from the preprocedure level reported by patients (p < 0.005). Further reductions in state anxiety levels were reported at 5 and 30 days postprocedure. The mean scores for state anxiety fell within the normal range at 30 days postprocedure (mean 32.75, SD = 10.97). However, at 5 days post-CNB, patients with confirmed malignancies reported significantly more anxiety than patients without malignancies (p = 0.002). This difference was not present at 30 days post-CNB (p = 0.17). Patients reported average pain scores of 2.0 (on a scale of 0-10) during the biopsy. This decreased to 1.3 at 24 hours, 0.3 at 5 days, and 0.2 at 30 days. Reported symptoms of acute stress related to the procedure significantly increased over the period between the 5-day interview and the 30-day interview. One (2%) patient reported avoidance of thoughts about CNB 5 days postprocedure and 5 (12%) patients reported this at 30 days postprocedure (p < 0.05). Patients undergoing CNB reported significant levels of state anxiety which were greatest at the time of biopsy. A significant decrease was observed at 24 hours postprocedure, despite the fact that biopsy results were not available to the patients. Self-reported levels of anxiety for the group, regardless of biopsy results, fell within the normal range by 30 days. Further research and interventions are recommended to address the management of anxiety for patients undergoing CNB.     

Large-Gauge Core Needle Biopsy of the Breast

Abstract: Large-gauge core needle biopsy (LGCNB) of the breast is gaining acceptance as a viable alternative to surgical excision. The procedure can be performed efficiently using ultrasound or stereotactic guidance. We report our experience with 137 LGCNB performed over a 40-month period. One hundred thirty-seven lesions in 125 patients were subjected to LGCNB. Fifty-nine procedures were performed using stereotactic guidance and 78 using ultrasound guidance. Stereotactic procedures utilized a prone table and ultrasound procedures used a freehand technique. All biopsies were performed with a 14-gauge core needle attached to an automated biopsy device. There were 53 malignant and 84 benign diagnoses in this group of 137 LGCNB. Surgical correlation is available in 46 of the 53 malignant cases. There were no false positives, though one lesion was missed at the initial surgical excision but retrieved at reexcision. Of the 84 benign cases, there has been surgical (n = 10) or mammographic follow-up (n = 32) in 42. The mean duration of mammographic follow-up is 13 months (range: 5–36 months). There was one false negative LGCNB. The sensitivity, specificity, positive predictive value, and negative predictive value in this series are 98%, 100%, 100% and 96%, respectively. LGCNB has a high degree of accuracy and is well accepted by patients. There are some persistent difficulties with the technique, such as ensuring compliance with follow-up recommendations among patients with benign results and excluding invasive carcinoma.?     

Efficiency of Core Biopsy for BI-RADS-5 Breast Lesions

Stereotactic biopsy has proven more cost effective for biopsy of lesions associated with moderately suspicious mammograms. Data regarding selection of stereotactic biopsy (CORE) instead of excisional biopsy (EB) as the first diagnostic procedure in patients with nonpalpable breast lesions and highest suspicion breast imaging-reporting and data system (BI-RADS)-5 mammograms are sparse. Records from a regional health system radiology database were screened for mammograms associated with image-guided biopsy. A total of 182 nonpalpable BI-RADS-5 lesions were sampled in 178 patients over 5 years, using CORE or EB. Initial surgical margins, number of surgeries, time from initial procedure to last related surgical procedure, and hospital and professional charges for related admissions were compared using chi-squared, t-test, and Wilcoxon Mann-Whitney tests. A total of 108 CORE and 74 EB were performed as the first diagnostic procedure. Invasive or in situ carcinoma was diagnosed in 156 (86%) of all biopsies, 95 in CORE and 61 in EB groups. Negative margins of the first surgical procedure were more frequent in CORE (n = 70, 74%) versus EB (n = 17, 28%), p < 0.05. Use of CORE was associated with fewer total surgical procedures per lesion (1.29 +/- 0.05 versus 1.8 +/- 0.05, p < 0.05). Time of initial diagnostic procedure to final treatment did not vary significantly according to group (27 +/- 2 days versus 22 +/- 2 days, CORE versus EB). Mean charges including the diagnostic procedure and all subsequent surgeries were not different between CORE and EB groups ($10,500 +/- 300 versus $11,500 +/- 500, p = 0.08). Use of CORE as the first procedure in patients with highly suspicious mammograms is associated with improved pathologic margins and need for fewer surgical procedures than EB, and should be considered the preferred initial diagnostic approach.

Limitations and Complications in the Utilization of Stereotaxic Core Breast Biopsy

Abstract: Stereotaxic core biopsy of the breast is becoming an increasingly utilized tool for the diagnosis of breast disease without surgery. It can increase the speed and decrease the cost and deformity associated with diagnosis. However, some shortcomings in the procedure exist and radiologists and patients should be aware of these.
Lesions that are in thin areas of the breast or close to the skin may be difficult t o biopsy with this technique. Lesions near the chest wall or in the axilla may be inaccessible with some equipment, especially prone tables. Small lesions may be totally removed, making localization of the area for wider surgical excision difficult if they are malignant. Some types of calcifications may be difficult t o sample.
Certain histologies require wider surgical excision when diagnosed with core biopsy. These include ductal atypia and radial scars. Areas of invasion associated with duct carcinoma in situ (DCIS) may be missed on core sampling. Major complications are rare and include bleeding and infection. Minor complications are ecchymosis, pain, and inability t o return t o normal activities for a day or more.     

Preoperative Profiling of Symptomatic Breast Cancer by Diagnostic Core Biopsy

Background Precise preoperative profiling of breast tumors could facilitate fuller consideration of (neo)adjuvant therapies. Methods Diagnostic core biopsy (DCB) accuracy in profiling the primary tumor was prospectively studied in 95 patients with operable breast cancer. The histological type and grade (hematoxylin and eosin staining) and membrane receptor status (semiquantitative immunohistochemistry for estrogen [ER] and progesterone [PR] receptors, as well as Her-2 antigen expression) were assigned by the DCB before surgery. These measures were then compared with those of the definitive surgical specimen available after operation. Results DCB correctly ascribed tumor type and grade and ER, PR, and Her-2 receptor status in most cases (correlating exactly in 97.5%, 77%, 68%, 71%, and 60%, respectively) with at least moderate concordance (weighted κ, >.41). When miscategorized, DCB consistently tended to upscore the receptor stain intensity compared with the surgical specimen (22%, 19%, and 27% had higher ER, PR, and Her-2 categorical scores, respectively). ER H-scores correlated best in specimens that stained strongly (224.4 ± 3 vs. 215.5 ± 5) and were significantly higher on DCB in those that stained either moderately (195.6 ± 8.2 vs. 156.8 ± 5.1; P < .0001) or weakly (157.1 ± 24.8 vs. 81.4 ± 4; P = .02). DCB accurately identified all tumors with clinically important ER and Her-2 expression. Furthermore, it promoted three patients into the therapeutically significant range of ER (n = 1) or Her-2 (n = 2) expression. ER negativity on DCB (n = 25) indicated a high-grade tumor (88%), although 11 (44%) patients also overexpressed Her-2. Significant Her-2 expression (n = 16) on DCB predicted the tumor as being poorly differentiated (80%) and both ER and PR negative (67%). Conclusions DCB accurately profiles clinically relevant measures of primary tumor cell differentiation. It also reliably categorizes patients with regard to (neo)adjuvant therapy before radical surgery is attempted.

Accuracy of 11-Gauge Vacuum-Assisted Core Biopsy of Mammographic Breast Lesions

Background: Image-guided percutaneous biopsy has largely replaced excisional biopsy of mammographic lesions. Vacuum-assisted core biopsy has improved sampling of such lesions. The objectives of this study were to define the accuracy of the vacuum-assisted 11-gauge stereotactic core biopsy in sampling of atypical ductal hyperplasia (ADH) and ductal carcinoma in situ (DCIS) and to define histologic and mammographic features of target lesions, which predict sampling errors.Methods: Between October 1996 and March 2000, 1341 patients underwent stereotactic 11-gauge vacuum-assisted biopsy. Patients with ADH or DCIS were encouraged to undergo excisional biopsy.Results: Surgical excision of 37 ADH lesions revealed 5 missed DCIS lesions and 1 missed invasive cancer. Twelve of 91 DCIS lesions were upstaged to invasive cancer upon excision. The underestimation rate was highest in patients with DCIS when the target lesion for biopsy was a zone of calcifications >1.5 cm. No correlation existed between the histologic features of DCIS lesions diagnosed by stereotactic biopsy and the presence of infiltrating disease on excision.Conclusions: Vacuum-assisted 11-gauge stereotactic core biopsy understages 13.2% and 13.5% of DCIS and ADH lesions, respectively. In patients with DCIS found by stereotactic biopsy, a target zone of calcifications >1.5 cm is associated with a higher underestimation rate of infiltrating disease.     

Histomorphologic Features of Biopsy Sites Following Excisional and Core Needle Biopsies of the Breast

Mammographic studies have documented a number of architectural changes occurring around breast biopsy sites. These changes are well described in the radiological literature, but similar studies do not appear to be present in the pathology literature. We reviewed 100 consecutive mastectomy specimens from women who had undergone prior core needle or excisional biopsies. Multiple sections of the needle tract or excisional biopsy site were reviewed and morphologic findings reported. Hemorrhage, fat necrosis, granulation tissue, necrosis of fibrous tissue, and epithelium along with fibrosis and foreign body type giant cells were common features. Less frequent were areas of synovial metaplasia, atypical spindle cells, atypical duct‐like structures, single atypical cells, squamous metaplasia, proliferations of abnormal blood vessels, and hemosiderin deposition. The misinterpretation of atypical spindle cells, single atypical cells, atypical duct‐like structures and squamous metaplasia could result in the false‐positive diagnosis of residual malignancy. Careful attention to the reactive nature of these changes aids in their distinction from carcinoma.
