AIMS Various biological parameters are now being evaluated as predictors for the response of chemohormonal therapy for breast cancer. Few studies compare these parameters between the primary lesions and metastatic regional lymph nodes of breast cancer. METHODS Immunohistochemical analyses for epidermal growth factor receptor (EGFR), c-erbB2 and p53(More)
In breast cancer, the rates of positivity for microsatellite instability (MSI), vary greatly in the literature. Using high-resolution fluorescent microsatellite analysis (HFRMA), we studied microsatellite alterations in 75 patients with sporadic breast cancer. In this system, several devices were prepared to improve reproducibility of polymerase chain(More)
In this retrospective study, the relationship between Akt activation and the efficacy of endocrine therapy for metastatic breast cancer was investigated. Thirty-six metastatic breast cancer patients, treated with endocrine therapy, were evaluated for the activation of Akt by an immunohistochemical assessment of the expression of phosphorylated Akt at Ser(More)
Cosmetic factors in the treatment of breast disease have long been neglected despite the fact that patients are highly concerned about the length and extent of the incision. Recent developments in both endoscopy and endoscopic devices have now made it possible to reach breast mass(es) from small incisions in the axilla. We describe the successful(More)
Comparing differential gene expression profiles established by cDNA microarray between normal cells (N), primary carcinoma cells (T), and metastatic carcinoma cells (M) may determine those critical genes directly associated with progression and metastasis of breast cancer. Total RNA was extracted by laser microdissection (LMD) from 20 slices of T, N and M(More)
The early results of 6 patients with a benign breast mass who underwent an endoscopic extirpation via an extra-mammary incision were presented. Under general anesthesia in either a lateral or supine position, a 12-mm and two 5-mm incisions in the infra-mammary line in 2 patients and in the mid-axillary line in the remaining 4 patients were made. The tumors(More)
Sentinel lymph node (SLN) biopsy is being evaluated in breast cancer patients to improve detection of metastases and to guide therapy with minimal morbidity. The aim of this study was to increase the sensitivity of tumor cell detection in SLNs using superior reverse transcription polymerase chain reaction (RT-PCR) for carcinoembryonic antigen (CEA) and(More)
Akt is a serine/threonine kinase that has been demonstrated to play an important role in survival when cells are exposed to different apoptotic stimuli. Recent studies show that aberrant activation of Akt in breast carcinoma is associated with a poor prognosis and resistance to endocrine therapy and chemotherapy. The Akt signaling pathway is currently(More)
The combination effect of docetaxel and capecitabine on tumour response rate and survival was demonstrated recently in metastatic breast cancer patients. This combination was based on an experimental hypothesis that taxane can increase tumour sensitivity to the effect of capecitabine through the upregulation of thymidine phosphorylase (TP), which is(More)
Few surrogate markers are available for predicting the survival benefit from chemotherapy in primary breast cancer. We examined tumor growth kinetics by assessing cytokeratin 18 neo-epitope (CK18NE), an apoptosis marker detected by M30 antibody and Ki-67 antigen, a proliferation marker detected by MIB-1 antibody in 72 primary breast cancer patients who(More)
