Rescue Regimen and High Dose Methotrexate in Management of Presistent Gestational Trophoplastic Neoplasia

September 11, 2017 updated by: Zahraa Magdy, Assiut University

Comparison Between Rescue Regimen and High Dose Methotrexate in the Managment of Presistent Gestational Trophoplastic Neoplasia :( A Randomized Controlled Trial )

Gestational trophoblastic neoplasia (GTN) are malignant lesions that arise from abnormal proliferation of placental trophoblast. The pathologic conditions that make up this entity include invasive partial and complete hydatidiform mole, choriocarcinoma, placental site trophoblastic tumor (PSTT), and epithelioid trophoblastic tumor (ETT). GTN often arises after molar pregnancies but can also occur after any gestation including miscarriages and term pregnancies. In the United States, hydatidiform moles are observed in approximately 1/600 therapeutic abortions and 1/1000-2000 pregnancies . Most cases of GTN are diagnosed when the serum hCG levels plateau or rise in patients being observed after the diagnosis of hydatidiform mole.These malignancies are highly susceptible to chemotherapy and it is often possible to achieve cure while preserving the woman's reproductive function

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

When reporting GTN data, it is useful to use both the FIGO anatomic staging system and prognostic scoring system . A FIGO score of 6 or less indicates low-risk GTN whereas a score of 7 or more identifies high-risk disease.

Table 1- FIGO Anatomical staging of gestational trophoblastic neoplasia:

Stage I Disease confined to the uterus Stage II Disease extends to the outside of the uterus, but is limited to the genital structures Stage III Disease extends to the lungs, with or without genital tract involvement Stage IV All other metastatic sites

RCOG guidelines (No. 38February 2010 ) recommends the use of rescue regimen of alternating methotrexate( MTX) and leucoverin for 8 days (class D). However, several protocols using MTX were described. No prospective randomised controlled trials have been done to compare the efficacy of resue regimen with the ther protocols. In a retrospective study done showed that high dose methotrexate regimen is more effective than the rescue regimen.

In addition, several concerns have been raised towards the use of leucoverin with methotrexate, although reducing the side effects, however, it may increase the resistence to the effect of MTX .

On the other hand, High dose regimen offers a less hospital stay which may be more convenient to the patients, together with the same incidence of side effects.

In our study we are going to compare the efficacy and tolerance of both regimens in patients diagnosed to have low risk PGTN.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
