Active clinical trials for "Trophoblastic Neoplasms"

RATIONALE: Collecting and storing samples of blood, urine, and tissue from patients undergoing a donor stem cell transplant to test in the laboratory may help the study of graft-versus-host disease in the future. PURPOSE: This research study is collecting and storing tissue and DNA samples from patients undergoing a donor stem cell transplant.

This laboratory study is collecting tumor tissue and blood samples from patients with gynecologic tumors. Collecting and storing samples of tumor tissue and blood from patients with cancer to study in the laboratory may help in the study of cancer.

Gestational trophoblastic disease comprises a spectrum of diseases with different propensity for local invasion and metastasis, that is, partial and complete hydatidiform mole, choriocarcinoma, and placental site trophoblastic tumor.All trophoblastic tumors produce hCG, and monitoring of therapy is largely based on the determination of hCG in serum. The conformational change of tumor markers during antineoplastic chemotherapy for cancer and its clinical meaning has only been rarely studied. In this study, we will try to understand the conformational change of the tumor marker (hCG) during chemotherapy.

Gestational trophoblastic tumors are characterized by their development from placental tissue and their high invasive and metastatic potential. These are rare tumors (1/50 000 pregnancies) affecting young women for whom conservative fertility treatments are preferred. The therapeutic strategy is based on a chemotherapy whose choice of protocol is based on a clinico-biological score, FIGO score, which includes tumor size, gonadotropic chorionic hormone level used as quantitative tumor marker, number and localization. metastases. A FIGO score ≤6 allows the use of monochemotherapy (methotrexate) with a 5-year survival of approximately 99.7%. Scores of 7 to 12 and ≥13 require multidrug therapy (EMA-CO) and are associated with 5-year survival of 95.1% and 61.6%, respectively. The chemotherapies currently used for the treatment of trophoblastic tumors have been described between the 1950s (methotrexate) and the 1980s (EMA-CO) and have a well documented toxicity regarding the risk of secondary tumors, early menopause or even death by toxicity. . To date, apart from the FIGO score, there is no predictor of resistance to chemotherapy in gestational trophoblastic tumors. However, among patients with a FIGO score ≤6 and receiving methotrexate in the first line, 9 to 46% will have a resistance and require a second line of treatment. Similarly, if the score is ≥7, 10 to 30% of patients receiving EMA-CO will require at least a second line of multidrug therapy. The hypothesis of PrediCTTro study is that tissue samples of gestational choriocarcinoma present a transcriptomic profile associated with the risk of further resistance to single or multiagent chemotherapy. The objective of PrediCTTro is to identify a transcriptomic signature able to predict resistance to single or multiagent chemotherapy.

We will try to use the novel analytical technique -Dual Polarisation Interferometry (DPI),to achieve detection the minimal amount of the human chorionic gonadotropin for early detection and strict monitor of the GTD.
