Fetal plasma IL-6 concentration is significantly associated with the presence of inflammatory lesions in the extraplacental membranes and umbilical cord. Fetuses with fetal plasma IL-6 > 11 pg/ml had a significantly higher rate of funisitis and/or chorionic vasculitis than fetuses with fetal plasma IL-6 < 11 pg/ml. These findings suggest that funisitis/chorionic vasculitis is the histological manifestation of the fetal inflammatory response syndrome.
Sixty cases of primary breast carcinoma have been studied using a monoclonal antibody, Ki67, which recognizes an antigen expressed by cells in G1, S, G2, and M phases of the cell cycle but not Go. A Ki67 score (positive cells/total tumour cells) was determined, and possible relationships between this index of cellular proliferation and a number of clinical and pathological parameters were investigated. There was a strong positive correlation between the Ki67 score and mitotic index (p less than 0.001), a weak negative correlation with age (p less than 0.02), and weak positive correlations with histological tumour grade (p less than 0.03), tumour necrosis (p less than 0.01), and cellular reaction (p less than 0.01). No relationship was noted between the Ki67 score and tumour size, nodal status, tumour oestrogen receptor levels, or menopausal status. The Ki67 score may prove to be an objective indicator of biological behaviour and thus be of clinical significance, particularly since it is not strongly related to other clinical and pathological parameters used in predicting outcome in breast carcinoma.
Objective To determine the frequency of port-site recurrences following laparoscopic surgical treatment Design Retrospective review of metastatic primary and recurrent gynaecological malignancies.Results Twenty-five women were studied. Twenty-four had metastatic disease at the time of laparoscopic surgery, 22 in association with a primary malignancy (cervix: n = 12, ovary: n = 7, endometrium: n = 3), and two in association with recurrent ovarian cancer; all received pelvic or extended field radiation or chemotherapy after surgery. One woman with Stage IIIC ovarian cancer, disease-free at the completion of neoadjuvant chemotherapy following laparotomy by a general surgeon, was included; she developed scalene node metastases 18 months after definitive laparoscopic surgery. Seventy-one 5 mm trocars and fifty 10 mm trocars (total n = 121) were used for surgery; thirty-one 10 mm trocar sites and forty-four 5 mm sites (total n = 75) received post-operative treatment with chemotherapy (n = 49) or radiation (n = 26). Four women (16%) developed recurrences in association with endometrial (n = 2) and cervical (n = 2) cancer at six trocar sites. All recurrences were associated with abdominopelvic andlor distant metastases, and all occurred at untreated 5 mm trocar sites. The difference in recurrence rates between 5 mm and 10 mm trocar sites (x2 = 6; P < 0.025), and between treated and untreated trocars (x2 = 5 ; P < 0.05) were both statistically significant (McNemar's test), but the effects of treatment and trocar size on the port-site recurrence rate were confounded.Conclusions Port-site recurrences are local manifestations of disseminated disease that result from the enhancement of tumour growth characteristic of healing tissues and can be prevented by appropriate post-operative therapy.of gynaecological malignancies metastatic at the time of surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
