Primary non-gestational choriocarcinoma of the uterine cervix: A case report

Background. Primary non-gestational choriocarcinoma of the female genital tract has been described in the ovaries and is very unusual in other genital sites.Case. Primary non-gestational uterine cervical choriocarcinoma was diagnosed in a patient, 32, single, without previous sexual contact nor antecedent pregnancy, admitted to the hospital with irregular vaginal hemorrhaging. Pelvic examination realized under anesthetic revealed a tumor mass occupying the uterine cervix. Metastases investigation was realized and the patient was accepted as FIGO IV: risk factor of 13. She was submitted to intensive chemotherapy and hysterectomy, showing general recovery, but died from drug-resistant disease 12 months later. Histological, immunohistochemical, and molecular genetics studies confirmed non-gestational choriocarcinoma.Conclusion. Primary non-gestational uterine cervical choriocarcinoma may arise from germ cell tumor or epithelial tissue. (c) 2005 Elsevier B.V. All rights reserved.

Primary Pulmonary Choriocarcinoma After Human Chorionic Gonadotropin Normalization Following Hydatidiform Mole A Report of Two Cases

BACKGROUND: Primary pulmonary choriocarcinoma (PPC) is rare and frequently leads to death.CASES: Two young patients presented with previous molar pregnancy and spontaneous serum human chorionic gonadotropin (hCG) normalization. Patient 1 was referred to our center after partial response to chemotherapy. Pulmonary lobectomy was performed, and hCG rapidly declined. During further chemotherapy, liver metastasis was detected by positron emission tomography. Right hepatectomy was performed, and hCG declined for 28 days, but increased again despite chemotherapy. This patient died from hepatic failure 3 years after diagnosis. Patient 2 presented with persistently high hCG, though the affected organ was not identified. Chemotherapy was unsuccessful. Patient reevaluation showed an isolated pulmonary mass. Pulmonary lobectomy was performed; 2 weeks later, hCG was normal and consolidation with 2 cycles of chemotherapy was administered. The patient has been in remission for 24 months. PPC was confirmed by histo pathology and immunohistochemistry in both cases. Gestational origin of the tumor was confirmed by molecular genetic analysis (polymorphic microsatellite markers).CONCLUSION: The possibility of choriocarcinoma cannot be overlooked in young women with an isolated pulmonary mass. Early diagnosis, prompt chemotherapy, and surgical resection in a specialized center improves the prognosis. (J Reprod Med 2010;55:311-316)

Geographical Distribution and Demographic Characteristics of Gestational Trophoblastic Disease

OBJECTIVE: To outline the geographical distribution pattern of gestational trophoblastic disease (GTD) in a referral center in Bahia, Brazil, and determine the demographics of the disease.STUDY DESIGN: We conducted a study of data retrieved from medical records of 140 GTD patients referred to our Trophoblastic Diseases Center in 2002-2007, assessing geographical distribution across health care districts, demographics, referral sources, and previous pregnancy status.RESULTS: The most common GTD types were hydatidiform mole (106, 75.7%), invasive mole (32, 22.9%), choriocarcinoma (1, 0.7%), and placental site trophoblastic tumor (1, 0.7%). GTD incidence was 8.5 in 1,000 deliveries. Most patients originated from the coastal region (East district), which includes the state capital (77.9%). The 20-34 age group predominated (65%). Education level (67.9% attended elementary school only) and employment rate (42.9%) were low. Secondary hospitals were the principal source of referral (84.3%), followed by self-referrals (15.7%). Regarding previous pregnancy status, 42.1% (n = 59) had had term pregnancy, 39.3% (n = 55) no pregnancy, 15% (n = 21) miscarriage, and 0.7% (n = 1) ectopic pregnancy; 4 patients (2.9%) had previous hydatidiform mole.CONCLUSION: GTD predominated in the peak fertility age group and among patients of unfavorable sociodemographic status.

Epidemiological Report on the Treatment of Patients with Gestational Trophoblastic Disease in 10 Brazilian Referral Centers Results After 12 Years Since International FIGO 2000 Consensus

OBJECTIVE: To evaluate treatment of Brazilian patients with gestational trophoblastic disease (GTD).STUDY DESIGN: A retrospective cohort study with analysis of medical reports performed in 10 Brazilian referral centers from January 2000 to December 2011.RESULTS: Of 5,250 patients 3 died (0.06%) at the time of uterine evacuation. Spontaneous remission of GTD (group G1) was observed in 4,103 cases, and 1,144 (21.8%) progressed to gestational trophoblastic neoplasia (GTN) (G2). In G1 2,716 (66.2%) had complete hydatidiform mole (HM) and 1,210, partial HM (29.5%); 3,772 patients (92.7%) recovered as noted in December 2012. In G2, of 1,118 patients treated, initial histopathological results of previous gestation were complete HM (77.5% [n = 886]), partial HM (8.8% [n = 100]), and choriocarcinoma (8.0% [n = 92]); 930 (81.3%) were low-risk, 200 (17.5%) were high-risk GTN, and 14 had placental site trophoblastic tumor (PSTT) (1.2%); cure was achieved in 1,078 cases (96.4%), but 26 patients (2.3%) died (4 low-risk [0.4%], 19 high-risk [9.5%], and 3 PSTT [21.4%]).CONCLUSION: The highest death rates were due to high-risk GTN and PSTT. Patients with molar pregnancy should be referred to a referral center for an early diagnosis and prompt treatment of GTN in order to reduce the morbidity and mortality found in advanced stages.
