Clinical Trial of IV Etoposide and Carboplatin and Cyclophosphamide Combination Chemotherapy Against Persistent or Recurrent Ovarian Cancer as 2nd or More Line Chemotherapy / 대한산부인과학회잡지

ABSTRACT

OBJECTIVE: We evaluated the effects and toxicities and cost effectiveness of iv etoposide-carboplatin- cyclophosphamide (ECC) combination chemotherapy against persistent or recurrent ovarian cancer who were previously heavily treated with one or more lines of chemotherapy which included platinum-paclitaxel- cyclophosphamide-topotecan based regimens. METHODS: Fifteen patients with a persistent or recurrent ovarian cancer, previously received first or more line chemotherapy, had been treated with ECC combination chemotherapy at Konsin Medical Center from September 2000 to October 2002. The ECC (iv etoposide-carboplatin-cyclophosphamide) combination chemotherapy consists of 100 mg/m2 etoposide iv and 500 mg/m2 cyclophosphamide iv in first day and 100 mg/m2 etoposide iv, 450 mg/m2 carboplatin iv in second day and 100 mg/m2 etoposide iv in third (and 4th-5th day if necessary) every 3-4 weeks. The response of patients was evaluated with the tumor marker (serum CA-125) and imaging studies (ultrasonogram, CT, MRI). The toxicities were defined according to the WHO toxicity criteria. RESULTS: The overall response rate by WHO criteria is 47%. In detail, partial response is 47%, Stable disease is 40% and progressive disease is 13%. The serologic CA-125 response rate is 64%, in detail serologic partial response is 64%, and serologic stable disease is 22% and serologic progressive disease is 14%. The median response duration is 9 months (4 to 12 months), the median time to response is 1 month (2 weeks to 2 months) and the median time to progression is 9 month (4 to 12 months). The most common side effect is nausea and vomiting and the bone marrow suppression is proved as a most serious side effect (grade 3 or more-13%). CONCLUSION: The iv etoposide-carboplatin-cyclophosphamide chemotherapy as a 2nd or more lines regimen against persistent or recurrent ovarian cancer is considerable.
