RESUMO

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. However, achieving sufficiently cosmetic results can be difficult, particularly in patients with tumors that are large or localized to the lower quadrant. To avoid breast deformities and asymmetries after BCS, immediate reconstruction using autologous tissue has been accepted as the standard option. Rhomboid skin and adipose flap repair is a simple, less invasive procedure than the myocutaneous flap, which has primarily been performed in patients with upper quadrant lesions. We herein report the cases of two patients with lower quadrant breast cancer with skin invasion, who underwent BCS with immediate breast repair using a rhomboid flap. This procedure is therefore worth considering as one of the first options for immediate repair after BCS.

RESUMO

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). Multivariate analysis indicated that vascularity (amount of blood flow), vascular flow pattern ("surrounding marginal flow" or "penetrating flow") and the incident angle of penetrating flow were significant findings for distinguishing between benign and malignant lesions. However, the sensitivity and specificity of B-mode alone did not improve significantly with CD addition (97.6% → 97.9%, 38.3% → 41.5%, respectively). We explored the causes of these negative results and found that age should have been considered when evaluating vascularity. Simulation experiments suggested that specificity is significantly improved when age is taken into consideration (38.3% → 46.0%, p < 0.001) and we thereby improved our diagnostic criteria.

RESUMO

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. All 705 DCIS lesions could be classified according to the JABTS classification system. The most frequent findings were hypo-echoic areas in the mammary gland (48.6%), followed by solid masses (28.0%) and duct abnormalities (10.2%) or mixed masses (8.1%). Distortion (1.3%), clustered microcysts (1.4%) and echogenic foci without a hypo-echoic area (2.5%) were uncommon. These results suggest that the concept of non-mass abnormalities is useful in detecting DCIS lesions.

RESUMO

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. However, only a few published reports have described sarcoid reactions in patients with colorectal cancer. CASE PRESENTATION: A 76-year-old woman underwent laparoscopic sigmoidectomy for sigmoid colon cancer. The postoperative follow-up computed tomography and 18-fluorodeoxyglucose positron emission tomography-computed tomography findings were suspicious for splenic metastasis of the sigmoid colon cancer. The patient then underwent laparoscopic splenectomy. Histopathological examination of the resected lymph nodes and spleen showed a non-caseating epithelioid cell granuloma. The patient was diagnosed with a sarcoid reaction. CONCLUSIONS: To our knowledge, this is the first report of a sarcoid reaction in the spleen and regional lymph nodes after colon cancer resection. The effect of a sarcoid reaction on the prognosis in patients with colorectal cancer has not been fully determined because of the small number of such cases. Further analyses involving a larger number of cases are necessary to evaluate the relationship between sarcoid reactions and prognosis in patients with colorectal cancer. We herein present an extremely rare case of a sarcoid reaction in the spleen and regional lymph nodes.

RESUMO

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. Fifteen patients who underwent chest wall resections for malignant disease (15/83) were classified as contiguous extension of neoplasms of neighboring organs, primary tumor, or local recurrence. The most common procedure in the malignant disease group was resection for contiguous spread of primary lung cancer (n = 7). The survival rate was 50% at 4 years. There were no serious postoperative complications. In some malignant diseases, complete local control with such a procedure may even lead to a long-term survival. This is a safe and an effective procedure for a variety of diseases.
