Secondary endpoint
1. The difference in mm between the tumor measured by CEUS and by pathological examination was obtained by measuring the difference between the pathological diameter and the maximum diameter calculated using B-mode. 2. The difference between the diameter found in B-mode compared to the pathological malignant diameter, and the difference in size between the diameter in CEUS measured against the pathological malignant diameter. 3. Pathological findings in the area where the lesion is detected by using CEUS rather than by B-mode. 4. Subgroup analysis for the difference between the pathological malignant diameter and B-mode/CEUS such as at the one-year post-diagnostic point, ER, HER2, lymphatic invasion and nuclear grade. 5. Analysis for the systemic error of length between CEUS/B-mode and pathological diameter. Exploratory endpoint 1. The difference of the maximum diameter in mm between the tumor measured by accumulated images and that found in default images in CEUS. 2. Pathological status (invasive, non-invasive, normal variation) of the parts, which were able to be observed by CEUS, but not B-mode. |

| 主な結果/Results | 各施設の評価において、腫瘍の最大径はB-modeで15 +/- 7 mm、CEUSで19 +/- 8 mm、病理(P)で17+/-9 mmであった。最大径の差についてはPに対するB-modeの差、CEUSの差はそれぞれ、-3+/-7 mm (p<0.0001)、1+/-6 mm (p = 0.0163)であった。中央判定において、腫瘍の最大径はB-modeで16 +/- 7 mm、CEUSで18 +/- 7 mm、病理(P)で17+/-9 mmであった。最大径の差についてはPに対するB-modeの差、CEUSの差はそれぞれ、-2 +/- 8 mm (p = 0.0114)、1 +/- 7 mm (p = 0.1921)であった。 | The mean widths as measured by the participating investigators were 15 +/- 7 mm (B-mode), 19 +/- 8 mm (CEUS), and 17+/-9 mm (P). The difference subtracted P from B-mode was - 3+/-7 mm (p<0.0001), and that from CEUS was 1+/-6 mm (p = 0.0163). The mean widths as measured by the independent reviewers were 16 +/- 7 mm (B-mode) and 18 +/- 7 mm (CEUS). The difference subtracted P from B-mode was - 2 +/- 8 mm (p = 0.0114), while that from CEUS was 1 +/- 7 mm (p = 0.1921). | ||||||

| 参加者背景/Baseline Characteristics | 乳癌に対する手術を施行された症例で、術前検査としてB-mode/CEUSを施行された症例を対象とした。手術時の病理結果から腫瘍径と病変範囲のマッピングがレポートと写真を含む形式で得られ、CEUS/B-modeの画像がデータとして得られていることを条件とした。さらに、B-mode/CEUSが近似した断層面/割面で評価されたことも条件とした。 | The patient eligibility criteria were as follows: breast surgery following a pathological diagnosis, complete data regarding tumor width and surgical specimen mapping including documentation and photos, B-mode and CEUS imaging performed prior to breast surgery, and similar probe angles between the B-mode and CEUS images and the direction of pathological excision. | ||||||
| 参加者の流れ/Participant flow | 2012/8から2017/1までの期間に10施設から得られた912例から、B-mode/CEUS/病理診断が近似した断層面/割面で評価されていない症例などを除外した759例を除外し、153例が登録された。1例がプローブ径を越えた腫瘍径であったため除外となり、152例が解析対象となった。 | The median period for registered in each institution was 19 months (1-38 months) between August 2012 and January 2017 at 10 institutions in Japan. 912 patients were screened who had received B-mode/CEUS and breast surgery with primary breast cancer. The most common recruiting issue was the criteria that only those patients be included who had had similar plane B-mode and CEUS, with corresponding pathological findings in the same direction. Accordingly, 759 patients were excluded, and only 153 were enrolled. After excluding one patient in whom the tumor diameter exceeded the width of the transducer, a final total of 152 patient data sets were analyzed. | ||||||
| 有害事象/Adverse events | なし | None. | ||||||
| 評価項目/Outcome measures | (1)主要評価項目
CEUSにおける最大径と病理組織学的に求められた最大径の差。 (2)副次的評価項目 B-modeにおける長径と病理組織学的に求められた最大径の差。 (3)探索的評価項目 B-modeで視認できずCEUSで造影効果に伴い視認可能となる範囲における病理学的所見 |
The primary endpoint was a comparison of maximum tumor width measured by CEUS and that by P (CEUS-P). The secondary endpoint was a comparison of maximum tumor width measured by B-mode and that by P (B-mode-P). In an additional exploratory analysis, we investigated the presence of pathologically cancerous or non-cancerous lesions in areas that showed enhancement on CEUS (invisible in B-mode) but were not visualized outside the area of visible tumor on B-mode. | ||||||
