Estrogen-progestin replacement therapy and endometrial cancer.
BACKGROUND It has been known for more than 20 years that estrogen replacement therapy substantially increases a woman's risk of developing endometrial cancer. To reduce this increased risk, progestins have been added to estrogen replacement therapy for between 5 and 15 days (usually 7 or 10 days) per "month" in a sequential fashion (sequential estrogen-progestin replacement therapy) or with eac...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولGrowth inhibition by progestins in a human endometrial cancer cell line with estrogen-independent progesterone receptors.
The presence of estrogen-independent progesterone receptors (PgR) was demonstrated in a subline of a human endometrial cancer cell line, Ishikawa cells, although the original Ishikawa cells contained estrogen-inducible PgR. Scatchard plot analysis of cytoplasmic binding data in our subline (IK-90) revealed a high affinity binding site for R5020 (Kd, 1.0 nM) with maximum binding sites of 158 fmo...
متن کاملRisk of endometrial cancer and estrogen replacement therapy history by CYP17 genotype.
Common variants among genes coding for enzymes in sex steroid biosynthetic pathways may influence the risk of endometrial cancer. We examined the association between endometrial cancer risk and estrogen replacement therapy (ERT) by CYP17 genotype using 51 incident cases and 391 randomly selected controls from a multiethnic cohort in Hawaii and Los Angeles, California. The relative risk of endom...
متن کاملProgestins and progesterone in hormone replacement therapy and the risk of breast cancer.
Controlled studies and most observational studies published over the last 5 years suggest that the addition of synthetic progestins to estrogen in hormone replacement therapy (HRT), particularly in continuous-combined regimen, increases the breast cancer (BC) risk compared to estrogen alone. By contrast, a recent study suggests that the addition of natural progesterone in cyclic regimens does n...
