ABSTRACT
With the application of chemotherapy,gestational trophoblastic neoplasia (GTN) has been the first of malignant tumors which can be cured by chemotherapy.However,the resistance and relapse still is the difficulty of treatment and the leading cause of death in patients.Approximately 20％ ～ 30％ of GTN tumor will be resistant to,or will relapse after cure.These resistant and relapsed lesions will require salvage therapy,which be treated with multi-agent chemotherapy with or without surgery and/or adjuvant radiation therapy.Various salvage regimens are used worldwide.It is unclear to determine which of the various salvage combinations,if any,was the most effect and the least toxic for the treatment of resistant or relapsed GTN.
ABSTRACT
Tricho-rhinophalangeal syndrome -1 gene(TRPS1),a new GATA family member,is highly prevalent in many tissues .It plays an important role in the regulation of cell proliferation and tissue development . The genetic missing of TRPS1 may lead to Tricho-rhinophalangeal syndrome .In recent years,studies have dem-onstrated that TRPS1 abnormal expression exists in a variety of tumors , and is associated with carcinogenesis , lymph node metastasis,pathological grading and clinical staging .Therefore,TRPS1 is considered as a potential tumor suppressor gene ,its overexpression may be one of mechanisms for carcinogenesis and progression of cancer . This review focuses on the role of TRPS 1 gene in carcinogenesis and progression of carcinoma ,and further to pro-vide a new biomarker for predicting cancer prognosis and therapy .
