In the present study, we determined the frequency and intensity of MRP protein expression by monoclonal antibody immunohistochemistry in a series of 259 resected invasive primary breast carcinomas, and we evaluated MRP immunoreactivity in relation to patient and tumour characteristics, relapse-free (RFS) and overall survival (OS). The immunostaining was(More)
Traditional clinicopathological features do not predict which patients will develop chemotherapy resistance. The TP53 gene is frequently altered in ovarian cancer but its prognostic implications are controversial. Little is known on the impact of TP53-downstream genes on prognosis. Using molecular and immunohistochemical analyses we examined TP53 and its(More)
Paracrine influences from fibroblasts derived from different sources of breast tissue on epithelial breast cancer cell growth in vitro were investigated. Medium conditioned (CM) by fibroblasts derived from tumours, adjacent normal breast tissue, and normal breast tissue obtained from reduction mammoplasty or from skin tissue significantly stimulated the(More)
Most image analysis systems (IAS) use black-and-white cameras. However, true color IASs are considered to be useful for quantification of immunohistologically stained structures. Using a true color IAS, we evaluated two methods of segmentation for quantification of area percentage of staining: one using fixed, preset thresholds and one using thresholds(More)
Epidermal growth factor receptor (EGFR) was studied in ovarian tumours with immunohistochemical (IH) and ligand-binding assay (LBA). Two different monoclonal antibodies (MoAbs: 2E9, EGFR1) with respect to detecting EGFR with different ligand-binding affinities (low, high and low) were used. When comparing the IH data of MoAbs, 2E9 and EGFR1 a significant(More)
The diagnostic value of the presence of anti-neuronal antibodies in serum was examined in 21 patients suspected of paraneoplastic disorders of the nervous system (NS) (group 1) and was compared to three control groups; group 2: 25 patients with a neurological disease, without cancer and no sign of paraneoplastic disorder; group 3: 27 patients with(More)
The prognostic value of EGF-R, IGF-1-R and SS-R, and of cytosolic estrogen-regulated pS2 protein, was studied in patients (pts) with primary breast and advanced ovarian cancer. Ovarian cancer tissues were negative for pS2 (by immunoradiometric assay) IGF-1-R and EGF-R contents (by ligand binding assay, LBA) were of no or moderate prognostic value for breast(More)
Neurologic complications of both the central and peripheral nervous systems occur frequently in patients with primary Sjögren's syndrome (primary SS), but the underlying cause of these complications is unknown. We studied the presence of antineuronal antibodies in relation to neurologic complications in a consecutive series of 45 patients with primary SS.(More)
Lung innervation has been studied in the past by methylene blue staining and silver impregnation and more recently by histochemical methods. These techniques give only a partial picture of the total innervation. We have delineated the innervation of the lung in man and three other mammalian species by immunostaining with antibodies to two new markers of(More)
To evaluate the sensitivity and specificity of immunohistochemical analysis in relation to the standard cytological examination of the cerebrospinal fluid (CSF) in patients with either a solid tumour or a haematological malignancy and possible leptomeningeal disease, 68 CSF-samples derived from 68 patients were examined. The sensitivity of(More)
