Abstract:
OBJECTIVEIn order to get better understanding of placental site trophoblastic tumor (PSTT), we have investigated 4 PSTT cases that diagnosed in our hospital and with literature reviews.
METHODSWe identified 4 patients of PSTT in our choriocarcinoma ward from Jan, 1985 to Dec, 2000 by retrospective analysis.
RESULTSPSTT accounted for 3.1@1000 of all trophoblastic diseases, the ratio of PSTT to choriocarcinoma was 1:138. The average age was 31. Two cases were secondary to hydatidiform mole with paremetrial or pulmonary metastasis respectively. All cases received hysterectomy and multiple chemotherapy. With a follow-up of 29 to 84 months, all patients are survived up to now.
CONCLUSIONSPSTT is a rare gestational trophoblastic tumor. Accurate pathological diagnosis is critical for proper treatment. The diagnosis and monitor are rather difficult because the beta-hCG are non-parallel to the growth and disappearance of the tumor. Operation plays an important role in its treatment, and multiple chemotherapy is helpful.
