Multicenter Prospective Study of Color Doppler Ultrasound for Breast Masses: Utility of Our Color Doppler Method.

The use of color Doppler ultrasound (CD) for distinguishing between benign and malignant breast lesions remains controversial. This study (JABTS BC-04 study) was aimed at confirming the usefulness of our CD diagnostic criteria. We evaluated ultrasound images of 1408 solid breast masses from 16 institutions in Japan (malignant: 839, benign: 569).

Ultrasound Image Classification of Ductal Carcinoma In Situ (DCIS) of the Breast: Analysis of 705 DCIS Lesions.

The Japan Association of Breast and Thyroid Sonology (JABTS) proposed, in 2003, a conceptual classification system for non-mass abnormalities to be applied in addition to the conventional concept of masses, to facilitate detecting ductal carcinoma in situ (DCIS) lesions. The aim of this study was to confirm the utility of this system and to clarify the distribution of these findings in DCIS lesions. Data on 705 surgically treated DCIS lesions from 16 institutions in Japan were retrospectively reviewed.

Sarcoid reaction in the spleen after sigmoid colon cancer resection: a case report.

Background: A sarcoid reaction is a phenomenon characterized by histologically proven granulomatous lesions without evidence of sarcoidosis. This pathology is a benign tumor itself, but several reports have described sarcoid reactions accompanying malignant tumors. Sarcoid reactions occur in various cancers, such as skin, lung, ovary, stomach, and breast cancers.

Esthetic result of rhomboid flap repair after breast-conserving surgery for lower quadrant breast cancer lesion with skin invasion: report of two cases.

Breast-conserving surgery (BCS) has been increasingly performed as a standard operative strategy for patients with breast cancer. The primary purpose of BCS is to acquire both local control and good cosmetic results. An insignificant difference in cancer treatment results has been shown between BCS and total mastectomy.

Chest wall resection in general thoracic surgery.

To clarify the incidence, indications, and efficacy of chest wall resection, a comprehensive review is needed. Chest wall resection was performed in 23 of 162 operations for thoracic disease over a nine-year period. Eight surgeries requiring chest wall resection for benign disease (8/79) were classified as fenestration or thoracoplasty for empyema, or resection of a benign neoplasm.
