Study summary

Study of hysteroscopic repeat curettage as the first-line treatment in low-risk postmolar gestational trophoblastic neoplasia compared with the MTX single drug chemotherapy

Read the detailed description

Gestational trophoblastic neoplasia (GTN) is a group of malignant tumors derived from placental trophoblastic cells, most of which are secondary to hydatidiform mole, and 95% of GTN patients present low-risk gestational trophoblastic neoplasia(LR-GTN).In the 1960s and 1970s, with the in-depth study of the disease, it was found that the malignant tumor was highly sensitive to chemotherapy and had ideal tumor marker HCG to guide the treatment and follow-up. Therefore, GTN was the best malignant tumor with the overall cure rate of LR-GTN nearly 100%.MTX single-drug multi-course chemotherapy is the classic treatment of LR-GTN recommended by FIGO, but most patients can develop gastrointestinal, blood and liver toxicity during chemotherapy. In addition, the longer treatment cycle also brings a lot of discomfort to patients.

In recent years, some scholars proposed that the selection of treatment regimen of LR-GTN secondary to hydatidiform pregnancy should consider the toxic and side effects of chemotherapy, the maintenance of patients' physiological functions and quality of life.Retrospective studies abroad have shown that LR-GTN delayed chemotherapy for hydatidiform mole pregnancy only started chemotherapy for LR-GTN at a certain stage of progression, and the results did not change the prognosis of LR-GTN but reduced the rate of chemotherapy.In addition, for some patients with ultra-low risk of LR-GTN in hydatidiform pregnancy undergoing hysteroscopic repeat curettage , the rate of chemotherapy can be reduced, the related costs can be reduced and the quality of life of patients can be improved.

In this non-Inferiority prospective, multicenter, randomized, controlled clinical study, with the routine use of a gleam of MTX single drug treatment scheme for comparison, comparing uterine cavity again emptying delay chemotherapy guided by parallel hysteroscopy surgery clinical curative effect and adverse reaction, which discuss after hydatidiform mole ultra-low dangerous GTN patients with uterine cavity emptying again guided by hysteroscopy surgery as a line of ultra low dangerous GTN patients after hydatidiform mole security and feasibility of the treatment.

  • Unable or unwilling to abide by protocol
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
