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
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.
Exclusion Criteria:
In the rescue regimen , we administer MTX in an eight-day treatment regimen consisting of four administrations of MTX given at 1 mg/kg I.M. every other day with folinic acid 0.1 mg/kg I.M,. given on intervening days.
Drug: rescue regimen
In the high dose MTX protocol, the patients will receive 100 mg/m2 intravenous (IV) MTX bolus followed by 200 mg/m2IV MTX infused over 12 hours followed by folinic acid
Drug: high dose methotrxate
In the rescue regimen , we administer MTX in an eight-day treatment regimen consisting of four administrations of TX given at 1 mg/kg I.M. every other day with folinic acid 0.1 mg/kg I.M,. given on intervening days.
In the high dose MTX protocol, the patients will receive 100 mg/m2 intravenous (IV) MTX bolus followed by 200 mg/m2IV MTX infused over 12 hours followed by folinic acid
