Breast core-needle biopsy: clinical trial of relaxation technique versus medication versus no intervention for anxiety reduction.

PURPOSE: To evaluate effectiveness of oral anxiolytic medication versus relaxation technique for anxiety reduction in women undergoing breast core-needle biopsy (CNB). MATERIALS AND METHODS: The institutional review board reviewed and approved the study. Informed consent was obtained from 143 consecutive women scheduled for breast CNB. Women were randomized as follows: no anxiety intervention (usual care group), relaxation therapy with an audiotape of classical music and ocean sounds during CNB (relaxation group), and 0.5-mg of alprazolam administered orally 15 minutes before CNB (medication group). Anxiety before, during, and 24 hours after the procedure was assessed with State-Trait Anxiety Inventory and self-reported visual analog scale from 0 (no anxiety) to 10 (worst anxiety). Data analysis was performed with statistical software. Descriptive statistics were computed for all variables. Group differences were determined with analysis of variance. Differences in mean values were assessed with Bonferroni multiple comparison procedure. Categorical demographic differences were assessed with chi(2) statistic. RESULTS: Preprocedural State-Trait Anxiety Inventory scores indicated that women were not inherently anxious: usual care group, score of 44.63; relaxation group, 45.74; and medication group, 49.1. Scores represented significantly elevated anxiety for women in all three groups when compared with the normative value of 35.12 (P < .0001), with no statistically significant differences between the scores of the three groups. Women in medication group reported significant reductions in anxiety (-44%) from levels determined before the procedure to levels determined during the procedure (P = .02) and significant reduction during the procedure when compared with changes in usual care (+15%) and relaxation (-8%) groups (P = .02). Women in all three groups reported significant reduction in anxiety from levels determined before the procedure to levels determined at 24 hours after it (P < .0001). There was no significant difference (P = .95) in 24-hour postprocedural anxiety levels among the three groups. CONCLUSION: Use of oral anxiolytic medication before breast CNB can significantly reduce anxiety women experience during the procedure.

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.
