Nucleolar organiser regions (NORs), which are important for regulating protein synthesis, were identified in 20 breast carcinomas by means of a silver (Ag) staining technique. Infiltrating neoplasms with metastases in four or more axillary lymph nodes possessed, on average, a greater number of AgNORs per cell nucleus compared with neoplasms without nodal(More)
AIMS To investigate the possible association of human papillomavirus (HPV) with endometrial hyperplasias and neoplasia. Does HPV play any role in the initiation or prognosis of endometrial adenocarcinomas? METHODS Twenty-five endometrial adenocarcinomas of the endometrioid cell type, with and without squamous differentiation, and twenty-four endometrial(More)
BACKGROUND Lymphomatoid papulosis (LyP) is a cutaneous clonal or polyclonal Ki-1 + T-cell lymphoproliferative disorder, morphologically resembling Ki-1 + anaplastic large cell lymphomas (Ki-1 + ALCL) or Hodgkin's disease (HD). Lymphomatoid papulosis usually has a characteristic benign clinical course with remissions and relapses of the cutaneous eruptions.(More)
Lectins are proteins and glycoproteins of non-immune origin which bind specifically to carbohydrate residues, agglutinate cells and/or precipitate complex carbohydrates. Lectin-binding patterns in normal, hyperplastic and neoplastic endometria were studied using four biotinylated lectins (Con A, LCA, e-PHA, l-PHA) and the avidin-biotin-peroxidase technique.(More)
The aim of this study was to investigate the expression of bcl-2 and p53 oncoproteins in a series of transitional cell bladder carcinomas and its relation to traditional prognostic indicators and patients’ survival. Specimens from 59 patients who underwent transurethral resection from March 1992 to February 1997 were included in this study. Tumors were(More)
This study was designed to investigate the prognostic relevance of ovarian tumour angiogenesis in terms of tumour angiogenic activity (TAA) and vascular survival ability (VSA), i.e. the ability of newly formed vessels to survive once incorporated into the main tumour mass. TAA was assessed at the edge of the invading tumour, while VSA was evaluated in inner(More)
Prostate cancer is the leading male malignancy in the Western world. Patients with prostate cancer have an unpredictable clinical course, as three biologically different types of tumor exist. This review summarises some of the recent progress made in understanding the biology of prostate cancer with special reference to the prognostic and predictive role of(More)
