Abstract

We analyzed a series of ovarian carcinomas from patients treated with cisplatin-based chemotherapy for loss of heterozygosity (LOH) to determine the relationship between microsatellite alteration and prognosis. Patients with tumors that had lost alleles at loci 3p14-21, 12qter, or 17p13.3 showed significantly reduced survival compared to patients with tumors that retained both alleles at those loci. The 5-year mortality rates for patients exhibiting allele loss and patients with allele retention were 50 and 41%, respectively, for the 3p14-21 locus (P=0.0023); 57 and 24%, respectively, for 12qter (P=0.0256); and 55 and 40%, respectively, for 17p13.3 (P=0.0489). A statistically significant difference was also observed with respect to fractional allelic loss (FAL), which was a significant indicator for disease recurrence (P=0.0227). The prognosis of patients with high FAL values were significantly worse compared to those with low FAL values (P=0.0306). Our results suggested that LOH at loci 3p14-21, 12qter, or 17p13.3 was a significant predictor of poor survival in ovarian carcinomas treated with cisplatin-based chemotherapy. Furthermore, the association of FAL value with therapy response indicated that ovarian carcinomas with high levels of chromosomal alteration may be more resistant to this type of chemotherapy.
