  • Title: Reduced systemic toxicity from superselective chemoembolization compared with systemic chemotherapy in patients with high-risk metastatic gestational trophoblastic disease.
    Author: Lang EK.
    Journal: Cardiovasc Intervent Radiol; 1997; 20(4):280-4. PubMed ID: 9211775.
    Abstract:
    PURPOSE: The efficacy of chemoembolization of primary and metastatic gestational trophoblastic neoplasms was studied. METHODS: Six female patients, 19-33 years old, with high-risk trophoblastic disease were subjected to one to five chemoembolizations in 3-week intervals. Three of the patients had metastases to the liver, 2 had local tumor extension to the pelvic wall, and all 5 had failed initial systemic chemotherapy. The sixth patient was treated for a trophoblastic remnant following surgical expression of a tubal pregnancy. For follow-up, beta hCG levels in urine and serum and dynamic or angio-computed tomograms were obtained in biweekly to 6-month intervals. RESULTS: Two of 3 patients with liver metastases are alive and free of disease 6 and 7 years after initial chemoembolization. The third is alive at 3 years but with evidence of recurrent disease. Two patients treated for locally invasive trophoblastic disease died 3 months and 4 years, respectively, after initial chemoembolization. One had a 2 1/2 -year remission. The patient treated for a trophoblastic remnant in the tube is alive and free of disease at 6-year follow-up. Hematologic toxicity occurred in only one. CONCLUSION: Selective chemoembolization in our small series of patients with high-risk trophoblastic disease was equally effective as results reported for multi-drug systemic chemotherapy but had markedly lower renal, liver, and hematologic toxicity.
