Host-derived MMP-9 expression, most likely in tumor-infiltrating macrophages, appears to play a critical role in angiogenesis and progressive growth of human ovarian tumors in mice.
Pathologic findings and immunohistochemistry are essential in making a diagnosis of LCNEC of the endometrium. Primary debulking and surgical staging is typically performed, but if a diagnosis of LCNEC can be made preoperatively with immunohistochemistry, surgeons should consider neoadjuvant chemotherapy due to its high grade histology and aggressive course. Otherwise adjuvant chemotherapy is usually given. Even with early stage disease, the prognosis seems poor. Due to the rarity of this aggressive malignancy, more data is needed to establish incidence.
Vaginal cuff dehiscence with associated evisceration of intraabdominal contents is a potentially severe complication of hysterectomy. We recommend counseling patients who undergo RA-TLH to abstain from vaginal intercourse for a minimum of 8-12 weeks.
Women with ovarian cancer who participate in clinical trials at this institution have improved survival compared with those who are treated with standard therapies. No other factors examined were associated with treatment completion or survival. Further, participation in clinical research does not vary by age, ethnicity, urban versus rural lifestyle, or cancer stage or histologic subtype. However, disclosure of this information to potential clinical trial participants may represent an ethical conflict and should be carefully considered in light of existing ethical guidelines for human subject research.
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.
