To optimize the prognostic value of DNA flow cytometry in breast cancer the authors calculated several parameters from the DNA histogram, including the DNA index, the size and number of aneuploid peaks as well as S-phase and G2/M-phase cell cycle fractions. Of these, DNA index and S-phase fraction (SPF) proved to be the most valuable prognostic indices. DNA(More)
The prognostic impact of DNA content and S-phase fraction (SPF) of tumour cells was studied in 93 patients with primary breast cancer. Aneuploid DNA content and high SPF were clearly associated with poor differentiation state of tumours and absence of steroid, especially progesterone receptors. Aneuploidy and high SPF tended to become more common with(More)
This prospective study consisted of 32 patients. In each patient, bile was collected during two separate endoscopic retrograde cholangiopancreatographies (ERCP) to study changes in biliary bacteriology and cytology. The mean interval between ERCPs was 20 months (15-29 months). Twenty-three patients had gallstones in the gallbladder, bile ducts, or both.(More)
Nissen fundoplication gives lasting relief from symptoms of gastro-oesophageal reflux and cures endoscopic oesophagitis effectively. The histological effect on the oesophageal mucosa is less clear. We studied the long-term histological effect of Nissen fundoplication on refractory gastro-oesophageal disease with erosive oesophagitis or Barrett's metaplasia(More)
Paraffin-embedded tumor samples from 157 ovarian cancer patients were analyzed by DNA flow cytometry. Tumor ploidy had prognostic significance in both early and advanced ovarian cancer. After adjusting for stage, residual tumor mass, histopathologic type, treatment, and age of patient in a Cox regression analysis, the relative risk of death was two-fold(More)
BACKGROUND The clinical syndrome of primary sclerosing cholangitis (PSC), diagnosed in about 5% of patients with ulcerative colitis (UC), has been shown to be associated with pouchitis after ileal pouch-anal anastomosis. The aim of this study was to ascertain whether UC patients with cholangitis on liver biopsy at proctocolectomy, with or without the(More)
We present a clinicopathological and flow cytometric evaluation of eight primary small cell carcinomas of the esophagus representing 1.5% of all esophageal malignancies diagnosed during a 22-year period (1965-1987) in the Tampere University Central Hospital. The mean age of the patients (four male and four female) was 67 years (range 55-75 years). Five(More)
We analyzed nuclear DNA content and S-phase fraction (SPF) from 157 paraffin-embedded ovarian tumors by flow cytometry and compared the results with the clinicopathological features of the tumors. DNA aneuploidy was more common and mean SPF was higher in advanced than in early-stage tumors (p less than 0.001). DNA aneuploidy was most often (75%) observed in(More)
Absorption of bile acids was investigated using 75Se-homotaurocholate (SeHCAT) in 27 patients with ileoanal anastomosis and J-pouch, 7 patients with conventional ileostomy and 9 non-operated patients with ulcerative colitis. Retention of SeHCAT at seven days was higher in non-operated patients than in patients with ileoanal anastomosis (P less than 0.001)(More)
