Prognostic markers and long-term outcome of placental-site trophoblastic tumours: a retrospective observational study.

Background: Placental-site trophoblastic tumours are a rare form of gestational trophoblastic disease and consequently information about optimum management or prognostic factors is restricted. We aimed to assess the long-term outcome of stage-adapted management by surgery, chemotherapy, or both for patients with the disorder.

Methods: 35 550 women were registered with gestational trophoblastic disease in the UK (1976-2006), of whom 62 were diagnosed with placental-site trophoblastic tumours and included, retrospectively, in the study.

Salvage chemotherapy of relapsed or high-risk gestational trophoblastic neoplasia (GTN) with paclitaxel/cisplatin alternating with paclitaxel/etoposide (TP/TE).

Objectives: To evaluate the efficacy and toxicity of paclitaxel and cisplatin alternating with paclitaxel and etoposide doublet regimen (TP/TE), for salvage of patients with high-risk gestational trophoblastic neoplasia (GTN).

Patients And Methods: Twenty-four patients with GTN received TP/TE. Sixteen had failed previous chemotherapy including six with cisplatin-based regimens (group A) and eight changed to TP/TE because of prior treatment-induced toxic effects (group B).

Management and outcome of healthy women with a persistently elevated beta-hCG.

Purpose: Raised serum beta human chorionic gonadotrophin (beta-hCG) not due to pregnancy can occur as a consequence of (1) gestational trophoblastic neoplasia (GTN), (2) non-gestational trophoblastic tumours, (3) a false-positive beta-hCG, (4) the menopause or (5) a high normal level. Accurate differentiation between these causes is vital to avoid potentially inappropriate investigations and therapies, which may induce infertility or other serious adverse events. Here we report the United Kingdom experience of patients with an elevated beta-hCG of initial uncertain cause and provide a clinical algorithm for the management of such cases.

Value of whole body 18FDG-PET to identify the active site of gestational trophoblastic neoplasia.

Objective: To evaluate the usefulness of positron emission tomography with 18-fluorodeoxyglucose (18FDG-PET) in locating residual or relapsed gestational trophoblastic neoplasia (GTN).

Study Design: The Charing Cross GTN database was screened, and 11 patients who had undergone 18FDG-PET were identified. A retrospective analysis was conducted to determine the value of this investigation as compared with other imaging modalities in clinical care.
