Placental site trophoblastic tumor: report of a tertiary center experience
Objective:
To analyze the clinical and pathological characteristics of placental site trophoblastic tumor (PSTT) cases and to discuss the diagnosis, treatment, and prognosis of PSTT.
Materials And Methods:
The clinical and pathological data of eight patients with PSTT at Istanbul Medical Faculty Hospital from 1988 to 2010 were analyzed retrospectively.
Results:
The mean age of the patients was 31 years. The antecedent pregnancy was full-term delivery in most of the patients (6/8, 75%). The mean interval from last pregnancy to diagnosis of PSTT was 35 months (range, six to 192). Serum human chorionic gonadotropin (hCG) levels at the time of diagnosis ranged from 0.1 to 2280 mIU/ml (mean, 614). All patients had Stage 1 disease and ultimately underwent hysterectomy. None of the patients received adjuvant chemotherapy. One patient died of an unknown reason, one month after the surgery. The rest of the patients were alive and without evidence of disease after an average of 3.5 years (range, one to 11) of follow-up.
Conclusion:
Hysterectomy alone can provide long-term survival in early-stage disease.
