UNLABELLED To evaluate the utility of CEA and CA 15.3 for early diagnosis of recurrence, serial serum determinations of both antigens were performed in 1023 patients (follow-up: 1-10 years, mean 6.2 years) with primary breast cancer (CA 15.3 in 533 cases) and no evidence of residual disease (NED) after radical treatment (radical mastectomy or simple(More)
PURPOSE The aim of this study was to evaluate the frequency of false-negative (FN) sentinel node procedures in patients with breast cancer and the subsequent clinical outcome in such patients. METHODS A total of 325 breast cancer patients underwent sentinel lymph node biopsy at our institution between June 1998 and May 2004. A 2-day protocol was used to(More)
PURPOSE Despite the widespread use of sentinel lymph node (SLN) biopsy in breast cancer patients, some controversy exists about the correct management of extra-axillary nodes, especially those located in the internal mammary chain. The aim of this study was to evaluate the incidence of SLNs in this region, calculate the lymphoscintigraphic and surgical(More)
The tumor markers, CEA and CA 15.3, were prospectively studied in the sera of 1057 untreated patients with locoregional breast cancer diagnosed from 1983 to 2001. Abnormal CEA and CA 15.3 serum levels were found in 13% and 18.8% of the patients, respectively. One tumor marker or another was abnormal in 22.8% of the patients. Both tumor markers were(More)
The aim of the study was to evaluate the contribution of preoperative breast magnetic resonance imaging (MRM) as an adjunct to mammography in assessing extent of pure ductal carcinoma in situ (DCIS) and to relate magnetic resonance imaging (MRI) findings to histopathological features. A retrospective analysis was conducted of 86 histologically proven cases(More)
Tumor markers were prospectively (CEA and CA 15.3) or retrospectively (c-erbB-2) studied in the sera of 503 untreated patients with breast cancer diagnosed from 1988 to 2001. Abnormal c-erbB-2 levels (> 15 U/ml) were found in 7%, CEA in 12% and CA 15.3 in 13% of the 503 patients. C-erbB-2 serum levels were only related to c-erbB-2 in tissue, with(More)
To evaluate the utility of c-erbB-2, carcinoembryonic antigen (CEA) and CA 15.3 in the early diagnosis of recurrence, serial serum determinations of these antigens were performed in 200 patients (follow-up 1-4 years, mean 2.2 years) with primary breast cancer and no evidence of residual disease (NED) after radical treatment (radical mastectomy or simple(More)
OBJECTIVE The purpose of our study was to describe the MRI findings of metaplastic carcinoma of the breast and to compare those findings with underlying histopathologic features. CONCLUSION Metaplastic carcinoma of the breast shows high signal intensity on T2-weighted MRI. This finding is related to the necrotic component of the tumor and may be useful(More)
C-erbB-2 serum levels were studied in the sera of 50 healthy subjects, 56 patients with benign breast diseases and 412 patients with breast cancer. Using 15 U/ml as the cut-off, no healthy subjects, patients with benign disease and only 2.4% of patients with no-evidence of disease had serum levels higher than this cut-off point. Abnormal c-erbB-2 levels(More)
