High-risk human papillomavirus (HPV) DNA/RNA testing provides higher sensitivity but lower specificity than cytology for the identification of high-grade cervical intraepithelial neoplasia (CIN). Several new HPV tests are now available for this purpose, and a direct comparison of their properties is needed. Seven tests were evaluated with samples in liquid(More)
Sections of formalin-fixed, paraffin-embedded tissue from 185 primary breast carcinomas were stained immunohistochemically using a polyclonal antibody against the c-erbB-2 oncoprotein. Positive staining, which is known to correlate with gene amplification, was associated with earlier relapse, shorter postrelapse survival, and shorter overall survival. Lymph(More)
Analysis of EGFr and ER was performed on tumour samples from 231 patients with operable breast cancer followed for up to 6 yr after surgery. The median duration of follow-up in patients still alive at the time of analysis was 45 months. Thirty-five percent of patients (82) had tumours greater than 10 fmol/mg 125I-EGF binding (EGFr+) and 47% (109) had(More)
PURPOSE To study the c-erbB-2 oncogene in primary transitional cell bladder cancer. MATERIALS AND METHODS Ninety-five patients with known clinical follow-up and epidermal growth factor receptor (EGFr) status were studied for expression of c-erbB-2 by immunostaining. Possible mechanisms underlying increased staining for c-erbB-2 protein were investigated(More)
We have recently shown that the integrity of the polyamine pathway is essential but not sufficient for expression of the mitogenic effect of estradiol (E2) in the N-nitrosomethylurea-induced rat mammary tumor grown in vitro in the soft agar clonogenic assay. To elucidate the mechanism of E2 action in this system, we tested whether E2 may stimulate tumor(More)
Evidence obtained in human breast cancer cell lines in culture suggests that estradiol stimulates the synthesis of secretory proteins which may, in turn, mediate its mitogenic effect. We questioned whether a similar mechanism could mediate the growth-promoting effect of PRL in the N-nitrosomethylurea-induced rat mammary tumor grown in soft agar, where PRL(More)
This study evaluated the role of polyamines in mediating the effect of ovine prolactin (oPRL) and ovine growth hormone (oGH) on the growth of the N-nitroso-N-methylurea [(NMU) CAS:684-93-5]-induced rat (Sprague-Dawley) mammary cancer cultured in soft agar. oPRL and oGH had a dose-related growth-promoting effect when added to NMU-induced mammary tumors(More)
The expression of cytosolic glutathione S-transferase (GST) isoenzymes has been assessed in a series of 74 primary human breast carcinomas using an immunohistochemical method. GST pi was detected in sections from all 74 tumours; it was expressed by non-epithelial (stromal and inflammatory) cells in 62 tumours (84 per cent), but by tumour epithelium in only(More)
OBJECTIVE To characterize possible endometrial defects in infertile women with isolated PCO morphology. DESIGN Prospective study. SETTING An academic hospital with an IVF unit. PATIENT(S) Women with primary unexplained infertility and isolated PCO, fertile women, and women with infertility secondary to male factor. INTERVENTION(S) Thirty-one women(More)
Infantile myofibromatosis (IM) is a condition characterized by the formation of spindle cell tumors of skin, soft tissue, and viscera. Although small vessel involvement by the process is a frequently identified and indeed diagnostically useful histological finding, involvement of large vessels is not widely reported. Fibromuscular dysplasia (FMD) is a(More)
