Objective To evaluate the use of the pre-operative tumour-associated trypsin inhibitor (TATI) level and residual tumour size at primary surgery as a prognostic indicators for patients with Stage III epithelial ovarian cancer.
Design Retrospective cohort study.
Setting Department of Obstetrics and Gynaecology, University Hospital, Helsinki, Finland.
Participants Ninety-eight women with Stage III ovarian cancer.
Methods TATI was measured by radioimmunoassay from serum samples obtained within one week before surgery. A cutoff value of 22 μg/L was used. Multivariate analysis included pre-operative TATI level, age, histologic grade and histologic type. Mantel-Cox test was used for calculating statistical significance of differences in survival between groups.
Main outcome measures Cumulative five-year survival, pre-operative serum TATI level and residual tumour size.
Results Surgery was optimal (residual tumour size ≤ 2 cm) in 55 patients and suboptimal (residual tumour size > 2 cm) in 43. Pre-operative TATI level ≤ 22 μg/L predicted better prognosis both in patients with optimal and suboptimal surgery compared with patients with pre-operative TATI level > 22 μ/L. Patients with optimal surgery and a pre-operative TATI > 22 μg/L had a twofold relative risk of death compared with those with a pre-operative TATI ≤ 22 μg/L. The cumulative survival was less than three years for patients with suboptimal surgery and pre-operative TATI > 22 μg/L.
Conclusions Pre-operative serum TATI in combination with residual tumour size may be useful in stratifying patients with Stage III ovarian cancer into different categories in randomised treatment trials. 相似文献

Summary. A newly-developed unidirectional force gauge was used to demonstrate that the urethral occlusive forces are unequal around the circumference of the female urethra. In the proximal two-thirds of the urethra significantly greater forces are exerted in the anterior position compared with those exerted in the lateral and posterior positions. By contrast the occlusive forces in the distal third of the urethra are greater in the posterior and lateral positions than in the anterior position. These findings hold true for both women with normal and abnormal urinary control. Rotational variations have previously been reported but have been thought to be artefact due to catheter stiffness; this study shows that rotational variations are genuine and not due to artefact. 相似文献

The effect of amniocentesis and drainage of amniotic fluid on lung development in Macacafascicularis
ALISON HISLOP Research Fellow D. V. I. FAIRWEATHER Professor R. J. BLACKWELL Deputy Chief Physicist SUSAN HOWARD Senior MLSO 《BJOG : an international journal of obstetrics and gynaecology》1984,91(9):835-842
Summary. Amniocentesis and withdrawal of amniotic fluid was performed on pregnant monkeys ( Macaco fascicularis ) at two stages in development, either between 47 and 64, or between 85 and 95 days gestation. After birth the lungs of each infant monkey were studied using precise morphometric techniques, and compared with those in a control group of animals. The lungs after amniocentesis had alveoli of normal maturity but reduced in number and increased in size, features which both reduce the relative area for gas exchange. There was also a reduction in the number of respiratory airways. These changes occurred regardless of the time of amniocentesis, the amount of fluid removed and even if the membranes were simply punctured with no fluid removal. There is some evidence to suggest that similar sublethal effects may be present in human infants after maternal amniocentesis. 相似文献
