OBJECTIVE The purpose of this study was to compare the cost-effectiveness of MR lymphangiography-based strategies with that of sentinel lymph node (SLN) biopsy alone in the axillary staging of early breast cancer. MATERIALS AND METHODS A decision-analytic Markov Model was developed to estimate quality-adjusted life expectancy and lifetime costs among 61-year-old women with clinically node-neg...

PURPOSE To retrospectively determine whether a Bayesian network (BN) computer model can accurately predict the probability of breast cancer on the basis of risk factors and mammographic appearance of microcalcifications, to improve the positive predictive value (PPV) of biopsy, with pathologic examination and follow-up as reference standards. MATERIALS AND METHODS The institutional review boa...

desmoid tumor of breast is a rare benign, locally aggressive tumor with a high recurrence rate. it has been associated with scar from previous breast surgery or trauma. especially in breast cancer patients with previous operation history, it may simulate recurrent breast cancer clinically and radiologically. we presented multimodality imaging findings (ultrasound, computed tomography, magnetic ...

Breast cancer after breast augmentation is not rare, but cases of bilateral breast cancer after augmentation are not often reported. A 43-year-old woman attended our hospital because of a mass in her left breast. She had undergone breast augmentation by implants 4 years before at a cosmetic surgery clinic. There were operative scars in her bilateral axilla. A detailed examination revealed bilat...

Sentinel lymph node biopsy is now accepted as the initial approach for women with early stage breast cancer with clinically node-negative disease. We performed a pooled analysis of trials comparing axillary lymph node dissection to sentinel lymph node biopsy in patients with early stage breast cancer and pathologically negative sentinel lymph node analysis. A systematic MEDLINE review identifie...

Imaging-guided percutaneous biopsy techniques have been developed to diagnose the lesions detected in breast cancer screening programs based on mammography. Although traditional fine-needle aspiration cytology continues to be indicated in some cases, in many others it has been supplanted by more modern techniques like core biopsy or vacuum-assisted biopsy guided by ultrasonography, stereotaxy, ...

PURPOSE Metastatic status of internal mammary lymph node (IMLN) has a clinical importance in assessing the stage and prognosis of breast cancer. But, when metastasis of IMLN is suspected; the management is controversial. We retrospectively reviewed 36 breast cancer patients who underwent IMLN biopsy, and investigated the pathologic status of IMLN which suspected metastasis with positron emissio...

OBJECTIVE A major controversial issue in the sentinel node biopsy of the breast is the applicability of sentinel node mapping in patients with the history of previous excisional biopsy of the breast lesions. In the current study, we evaluated the reproducibility of lymphoscintigraphy before and after excisional biopsy of the primary breast lesions using superficial peri-areolar injection of the...

Epidemiological studies using the histological classification of Page for benign breast disease consistently demonstrate a positive association between atypical hyperplasia and the subsequent development of breast cancer. However, atypical hyperplasia is of either lobular or ductal types, and breast cancer risk in relation to type of atypical hyperplasia has not been Studied extensively. Thus, ...
