  • Gestational trophoblastic disease (GTD) is an unusual disease occurring in pregnancy that originates from abnormal trophoblastic cells and comprises a group of diseases with different properties of invasion, metastasis and recurrence. The GTD group includes hydatidiform moles and gestational trophoblastic neoplasms (GTNs), with GTNs being divided into invasive moles, choriocarcinoma, placental site trophoblastic tumors and epithelioid trophoblastic tumors. The present review focuses on current effective treatments for GTD, including conventional and novel promising direct enzyme prodrug therapies (DEPTs). Conventional therapies, such as chemotherapy and hysterectomy, are currently used in a clinical setting; however, the use of diverse DEPTs, including antibody-DEPT and gene-DEPT is also being attempted to cure GTNs. In addition, gene delivery tools using genetically engineered neural stem cells (NSCs) are presently being examined for the treatment of GTNs. The tumor-tropism of NSCs by chemoattractant factors is a unique characteristic of these cells and can serve as a vehicle to deliver anticancer agents. Previous studies have demonstrated that injection with NSC-expressing suicide genes into xenograft animal models has a significant inhibitory effect on tumor growth. Stem cells can be genetically engineered to express anticancer genes, which migrate to the metastatic sites and selectively target cancer cells, and are considered to effectively target metastatic GTNs. However, the safety issue of stem cell therapy, such as tumorigenesis, remains a challenge. Novel therapies comprising a combination of conventional and novel promising treatments are anticipated to be definitive treatments for metastasized and/or recurrent patients with GTNs.

  • Extrauterine epithelioid trophoblastic tumors constitute an extremely rare gestational trophoblastic disease. We report the case of an extrauterine trophoblastic tumor that was incidentally detected in the left lung. Squamous cell carcinoma was suspected after microscopically examining the specimen obtained upon preoperative needle biopsy. After surgery, the tumor was confirmed by microscopic findings and immunohistochemical features.

  • 임신성 융모상피암은 임신으로 생성되는 영양아 세포에서 기원하는 악성도가 높은 암이다. 이 암은 초기에 폐 전이를 일으키며, 폐 전이는 경계가 명확한 수개의 결절형태로 나타나는 것이 가장 흔하다. 그러나 간혹 고립성 폐전이를 일으켜 진단이 어려울 때가 있다. 저자들은 각각 일측폐의 전체, 동전양 병변, 괴사성 종양의 소견을 보인 세유형을 보고하며 융모성 질환의 발생빈도가 높은 지역에서는 여성의 고립성 폐병변의 감별에서 산부인과 병력과 융모성 성선자극 호르몬 측정의 중요성을 강조한다.

  • Invasion of trophoblasts into maternal uterine tissue is essential for establishing mature feto-maternal circulation. The trophoblast invasion associated with placentation is similar to tumor invasion. In this study, we investigated the role of KAI1, an anti-metastasis factor, at the maternal-fetal interface during placentation. Mouse embryos were obtained from gestational days 5.5 (E5.5) to E13.5. Immunohistochemical analysis revealed that KAI1 was expressed on decidual cells around the track made when a fertilized ovum invaded the endometrium, at days E5.5 and E7.5, and on trophoblast giant cells, along the central maternal artery of the placenta at E9.5. KAI1 in trophoblast giant cells was increased at E11.5, and then decreased at E13.5. Furthermore, KAI1 was upregulated during the forskolin-mediated trophoblastic differentiation of BeWo cells. Collectively, these results indicate that KAI1 is differentially expressed in decidual cells and trophoblasts at the maternal-fetal interface, suggesting that KAI1 prevents trophoblast invasion during placentation.

  • 목적 자궁체부암 출혈에 대한 경카테터 동맥 색전술의 효과와 안전성을 평가하였다. 대상과 방법 20년 동안 자궁체부암 출혈로 경카테터 동맥 색전술(transcatheter arterial embolization; 이하 TAE)을 시행 받은 여섯 명의 환자들의 자료를 후향적으로 수집하였다. 혈관조영술 및 단면 영상 소견, TAE의 세부사항과 임상 경과를 탐구하였으며, TAE의 기술적, 임상적 성공률(technical and clinical success rate)을 각각 계산하였다. 결과 환자군은 자궁내막양 선암종, 육종, 그리고 임신융모종양으로 이루어졌으며, 대부분이 말기 암 환자들이었다. 출혈은 네 명의 환자에서 질출혈로 나타났다. 여섯 명의 환자들에서 일곱 번의 TAE가 시행되었고, 모든 TAE 시술에서 기술적 성공이 달성되었다. 자궁절제술을 받은 두 명의 환자들에서는 골반강 내 재발한 종양의 출혈이 혈변으로 나타났고, 이 환자들에서도 TAE는 기술적 성공을 보였다. 임상적 성공률은 50%로 절반의 환자에서 일주일 이상 출혈 조절이 되었다. 재출혈은 한 명의 환자에서 사망과 직접적으로 연관되었다. 한 명의 환자에서 시술 다음 날 경미한 부작용이 있었다. 결론 TAE는 자궁체부암 출혈에 대한 효과적이고 안전한 방법이며 특히 진행암, 말기암 환자들의 질병 경과 중의 위험한 시기에서 고려될 수 있다.
