Leiomyomas are common in the genitourinary and gastrointestinal tracts and less frequent in skin and soft tissue. It is quite uncommon for them to develop in the breast, especially in the breast parenchyma. Only 12 cases of leiomyoma in the breast parenchyma proper apart from the areola have been reported. We present a thirteenth case, the first to be(More)
PURPOSE This research aimed to establish a diagnostic technique for breast cancer using nipple discharge (ND), with the objective of preventive diagnosis. ND has been proposed as a source of secreted proteomes that reflect early pathological changes in the ductal-lobular epithelial microenvironment, and could thus provide breast-specific cancer biomarkers(More)
A prospective randomized study among 3 preoperative modalities, which consisted of intra-arterial infusion chemotherapy (I.A.), systemic chemotherapy (I.V.) and nontreated group, was carried out on 70 patients with advanced breast cancer. The results were as follows. (1) The response rate of primary lesions to I.A. (68.2%) was significantly higher than that(More)
To identify the genetic prognostic markers for breast cancer, we analyzed loss of heterozygosity (LOH) at 11p, 16q, 17p, 17q, and 18q, as well as amplification of theERBB2, INT2, andMYC genes, in 131 patients with breast carcinoma, 49 of whom had lymph node involvement, but none of whom had distant metastases. Among the several chromosome arms tested, LOH(More)
We studied the therapeutic usefulness of low dose 5'-deoxy-5-fluorouridine (5'-DFUR) alone and in combination with medroxyprogesterone acetate (MPA) or tamoxifen (TAM). As first line therapy, 58 patients with advanced and recurrent breast cancer were assigned to receive Regimen A (5'-DFUR 600 mg/body/day daily + TAM 30 mg/body/day daily), Regimen B (5'-DFUR(More)
A comparative study of 5'-DFUR 600 mg/day alone (C-arm) or in combination with TAM 30 mg/day (A-arm) or MPA 600 mg/day (B-arm) was carried out. Thirty-four patients (aged 80 or less) with no prior treatment were evaluable, and the following results were obtained. 1) Patient characteristics were similar in each treatment group and the compliance in all(More)
e11531 Background: Our aim was to define the role of MSKCC nomogram in avoiding conventional axillary dissection of one node-metastasis breast cancer patients. METHODS Between January 2009 to November 2010, clinically axillary node negative consecutive 186 patients underwent sentinel lymph node biopsy using 12 mg Indigo carmine in our institution. (More)
A prospective randomized study was carried out to evaluate the effectiveness of MPA in the treatment of breast cancer by comparing low dose (600 mg/day) with high dose (1,200 mg/day) of MPA. In 35 evaluable cases, the response rate to treatment was 40.0% (8/20) with low dose MPA and 26.7% (4/15) with high dose MPA. There was no significant difference(More)
RATIONALE AND OBJECTIVES The aim of this study was to evaluate the breast cancer diagnostic capability of "dual-side readout" computed radiography-based mammography (DRCRM) with a 50-microm pixel size compared to that of conventional film-screen mammography (FSM). MATERIALS AND METHODS Thirty patients who were scheduled for surgical treatment for breast(More)
Doxorubicin (ADM) and epirubicin (epi-ADM) were tested at a dose of 150mg given intraarterially to 31 patients (ADM 14, epi-ADM 17) with advanced breast cancer. The clinical response rate was 78.6% in ADM (1 CR and 10 PR) and 76.5% in epi-ADM (1 CR and 12 PR). The histological response rate of 57.1% was also obtained in ADM and 56.3% in epi-ADM. No(More)
