초록/요약
Purpose: The aim of this study was to investigate any difference of ultrasound findings for palpable and nonpalpable breast cancers. Methods: Two hundred breast cancer patients that had undergone preoperative ultrasound and surgery were enrolled in the study. A total of 126 cancers were palpable, and the remaining 74 cancers were nonpalpable. We compared lesion characteristics using ultrasound images according to the BI-RADS®-Ultrasound guidelines of the American College of Radiology. A crude odds ratio (OR) and 95% confidence interval (CI) were calculated for a comparison of the palpable and nonpalpable breast cancers. Results: Nonpalpable cancers displayed more often an oval shape (OR = 0.35, 95% CI = 0.17 – 0.70), no posterior acoustic features (OR = 0.50, 95% CI = 0.28 – 0.89), and a parallel orientation (OR = 0.50, 95% CI = 0.28 – 0.89). An irregular shape (OR = 2.98, 95% CI = 1.60 – 5.54), a spiculated margin (OR = 2.66, 95% CI = 1.23 – 5.74), and a combined pattern of posterior acoustic features (OR = 7.20, 95% CI = 1.64 – 31.66) were more commonly observed in the palpable cancers. Conclusion: Palpable and nonpalpable breast cancers were found to have different ultrasound characteristics.
