Epidermal growth factor receptor (EGFr) and cytosolic (cER) and nuclear (nER) estradiol receptors were quantified in 220 primary breast cancers. The EGFr was significantly more frequent (chi 2 = 5.9; P less than 0.025) and its concentration was significantly higher (P less than 0.001) among ER- tumors than in ER+ tumors. There was a significantly greater(More)
Amplifications of neu and c-myc were evaluated in 218 and 145 breast cancers (BC), respectively. Oncogene amplifications were determined for the most part by Southern blot. An association between the proportion of nodes affected and the intensity of neu amplification in estadiol receptor negative (ER-) BC was found (P = 0.028), which was confirmed by the(More)
The DR-locus controlled B-cell antigens were studied in 163 unrelated Spanish coeliac children and 68 families of this group, nine of them with more than one coeliac patient, to obtain more information about the association between these antigens and coeliac disease. The results show that the most common coeliac phenotypes are DR3/DR7, DR7/DR5, DR3/other(More)
PURPOSE The present report attempts to clarify whether there is a relationship between aromatase activity (ARAC) and estradiol (E2), hormonal receptors, E2 receptor (ER), and epidermal growth factor receptor (EGFR), as well as with tumor stage and histopathology in human breast cancers. MATERIALS AND METHODS We studied 225 breast carcinomas, 67 of which(More)
Ninety-three Spanish children suffering from coeliac disease and 103 control subjects from the same area were screened for the amount of alpha 1-antitrypsin (alpha 1AT) and for any electrophoretic variations in it. In this case-control study no significant differences were detected either in phenotype distribution or amount. The present results indicate(More)
There is a subset of patients with failed ablation of the cavotricuspid isthmus (CTI) using standard catheters and with 10% of the patients having recurrences. The purpose of this study was to compare the cooled and standard ablation with regard to acute successful electrophysiological achievement of bidirectional isthmus block and the subacute anatomic(More)
Four cases of congenital isolated atresia of the left pulmonary veins were observed over a 12-year period. The diagnosis was established through radionuclide pulmonary perfusion studies together with cardiac catheterization and pulmonary arteriography. Both procedures showed an elevated pulmonary pressure wedge and decreased blood flow with late poor(More)
Angiosarcoma of the breast is quite rare, and the development of cutaneous angiosarcoma after segmental mastectomy and radiation therapy is even less common. A cytogenetic analysis of a mammary angiosarcoma arising in a breast after previous irradiation and segmental mastectomy for infiltrating ductal carcinoma revealed multiple clonal rearrangements(More)
