خانم 69 ساله یائسه ای به دنبال خونریزی شدید واژینال به مدت 70 روز مراجعه کرد. در سونوگرافی بیمار، توده ای به قطر 7 میلی-متر در رحم گزارش گردید. در بررسی های تشخیصی، سطح سرمی بالای ?-hcg بدون وجود شواهدی از حاملگی یافت شد. در آسیب شناسی حین عمل جراحی هیسترکتومی توتال و سالپنگوافورکتومی دو طرفه، سرطان اندومتر شامل دو نوع آدنواسکواموس و پاپیلری سروز گزارش شد که از یافته های بسیار نادراست. به نظر م...
BACKGROUND Anaplastic thyroid carcinoma (ATC) is a rare, aggressive malignancy with a median survival of five months. Multimodality treatment is associated with some improvement in survival, but patients are only infrequently curable. Although β-hCG secretion has been reported in many neoplasms, it has never been described in ATC. The objectives of this study were to report a case of β-hCG-secr...
BACKGROUND Pathological examination combined with tumor markers has become a standard for the diagnosis of intracranial germ cell tumors (ICGCTs), but the current concept of 'secreting germ cell tumors' and three empirically highly specific diagnostic criteria (β-hCG ≥ 50 IU/L or αFP ≥ 10 ng/mL; β-hCG ≥ 100 IU/L or αFP ≥ 50 ng/mL; β-hCG > 50 IU/L or αFP > 25 ng/mL) are not based upon pathology ...
BACKGROUND Gestational trophoblastic neoplasia (GTN) disease is excessive and inappropriate proliferation of trophoblast after termination of the pregnancy. Many attempts have been made to improve follow-up procedures, but no studies have evaluated Human Chorionic Gonadotrophin (HCG) as a post treatment indicator. Thus we aimed to know β-HCG variability in post treatment pregnancies. METHODS ...
OBJECTIVE To determine whether the serum β-human chorionic gonadotropin (hCG) profile following preimplantation genetic diagnosis (PGD) is lower than that of intracytoplasmic sperm injection (ICSI) cycles. METHODS A total of 129 PGD cycles and 1,161 age-matched ICSI cycles, which resulted in pregnancy (serum β-hCG≥5 mIU/mL) on post-ovulation day (POD) 12 were included. We compared the mean se...
Purpose: Trophoblastic cancers (Choriocarcinoma, testicular and ovarian germ cell malignancies) secrete hyperglycosylated hCG and non-trophoblastic cancers secrete hyperglycosylated hCG free βsubunit.Both are structural variants of hCG independent to the hormone hCG. They are autocrines acting on a transforming growth factor β-II (TGF-β-II), receptor not acting on the hormone receptor. Here the...
BACKGROUND Beta (β)-human chorionic gonadotropin (β-HCG) is used to confirm the diagnosis and plan treatment of intracranial germinomas. However, the cutoff values of serum β-HCG in diagnosis of intracranial germinomas reported in the literature are inconsistent. To establish an appropriate cutoff value of serum β-HCG for diagnosis of intracranial germinomas, we retrospectively reviewed the rec...
Objectives We would like to determine the best treatment option depending of ectopic pregnancy situation. METHODS. This is a retrospective and cohort study that registered all women admitted in Obstetrics and Gynecologic “Queen Geraldine” Hospital during June 2003 until 2008. There are admitted 228 women diagnosed with Ectopic Pregnancy that are treated in our Hospital. Results. Unruptured ecto...
این پژوهش با الهام گرفتن از نتایج یک طرح مطالعاتی کاربردی، رویکرد سلسله‌مراتبی جهت پیگیری فرایند توسعه تأمین‌کنندگان و حمایت تصمیمات موجود در هر مراحل آن ارائه می‌کند. ابتدا، زمینه‌های تأمین نیازمند سپس واجد شرایط هریک زمینه‌ها به کمک تصمیم‌گیری چندشاخصه بهترین-بدترین مشخص می‌گردند. معیارهای شناسایی نیز مرور مطالعات پیشین بهره‌گیری نظرات خبرگان حوزه‌ی خرید استخراج‌شده‌اند. درنهایت، مدل ریاضی ...
Overexpression of beta-human chorionic gonadotropin (β-hCG) is frequently associated with germ cell tumours, especially choriocarcinoma. Ectopic secretion of β-hCG by non-small cell lung cancer is exceptional. We present an exceedingly rare case of pulmonary adenocarcinoma that secretes β-hCG. Our patient is a 62-year-old postmenopausal woman, a nonsmoker, who presented with a six-month history...
