Image-Guided Robotic Interventions for Breast Biopsy and Ablative Therapies: Challenges and Opportunities

Abstract Objective Image-guided breast biopsies are safe, efficient, and reliable. However, patients are often anxious about these procedures, particularly those who have never undergone a prior biopsy. Methods This prospective IRB-approved study surveyed 163 patients undergoing their first breast biopsy. Participants provided informed consent and completed a short written survey prior to and immediately after their procedure. Level of anxiety as well as anticipated and actual levels of pain prior to and following the procedure were assessed using a 0–10-point Likert scale. Correlation, bivariate, and regression analyses were performed. Results Regarding the biopsy experience, 133/163 (81.6%) of patients reported it as better than expected. Anxiety decreased significantly from a prebiopsy mean score of 5.52 to a postbiopsy mean score of 2.25 (P < 0.001). Average and greatest pain experienced during the procedure had mean scores of 2.03 and 2.77, respectively, both significantly lower compared to preprocedural expectation (mean 4.53) (P < 0.001). Lower pain scores were reported in US-guided procedures compared to stereotactic- and MRI-guided biopsies (P < 0.001). No significant differences in pain scores were seen in those undergoing single versus multiple biopsies, or when benign, elevated-risk, or malignant lesions were sampled. Positive correlations were seen with prebiopsy anxiety levels and procedural pain as well as with anticipated pain and actual procedural pain. Conclusion Image-guided biopsies are often better tolerated by patients than anticipated. We stress the benefit of conveying this information to patients prior to biopsy, as decreased anxiety correlates with lower levels of pain experienced during the procedure.

Institutional Review

Background: The management of intraductal papilloma without atypia (IDP) in breast needle biopsy remains controversial. This study investigates the upgrade rate of IDP to carcinoma and clinical and radiologic features predictive of an upgrade. Methods: Patients with a diagnosis of IDP on image-guided (mammography, ultrasound, magnetic resonance imaging) core needle or vacuum-assisted biopsy and surgical excision of this lesion at a certified breast center between 2007 and 2017 were included in this institutional review board-approved retrospective study. Appropriate statistical tests were performed to assess clinical and radiologic characteristics associated with an upgrade to malignancy at excision. Results: For 60 women with 62 surgically removed IDPs, the upgrade rate to malignancy was 16.1% (10 upgrades, 4 invasive ductal carcinoma, 6 ductal carcinoma in situ). IDPs with upgrade to carcinoma showed a significantly greater distance to the nipple (63.5 vs. 36.8 mm; p = 0.012). No significant associations were found between upgrade to carcinoma and age, menopausal status, lesion size, microcalcifications, BI-RADS descriptors, initial BI-RADS category, and biopsy modality. Conclusion: The upgrade rate at excision for IDPs diagnosed with needle biopsy was higher than expected according to some guideline recommendations. Observation only might not be appropriate for all patients with IDP, particularly for those with peripheral IDP.

The Impact

We sought to evaluate the impact of needle core size and number of core samples on diagnostic accuracy and upgrade rates for image-guided core needle biopsies of the breast. A total of 234 patients underwent image-guided percutaneous needle biopsies and subsequent surgical excision. Large-core needles (9 gauge or less) were used in 14.5 per cent of cases and the remainder were performed with smaller core needles. More than four core samples were taken in 78.9 per cent of patients. In 71.8 per cent of cases, needle biopsy pathology matched surgical excision pathology. After surgical excision, upgraded pathology was revealed in 10.7 per cent of cases. Of 11 patients (52.4%) with benign needle core pathology who had upgraded final pathology on surgical excision, 10 had a Breast Imaging Recording and Data System score 4 or 5 imaging study. Lesions smaller than 10 mm were more likely to be misdiagnosed ( P = 0.01) or have upgraded pathology ( P = 0.009). Other predictors of upgraded pathology were patient age 50 years or older ( P = 0.03) and taking four or fewer core samples ( P = 0.003). Needle core size did not impact accuracy or upgrade rates. Surgeons should exercise caution when interpreting needle biopsy results with older patients, smaller lesions, and limited sampling. Discordant pathology and imaging still mandate surgical confirmation.
