Objectives

Narrative objectives1

We examine effectiveness and safety of the combination therapy of substitution of antiandrogen or adding antiandrogen to LH-RH analogue with tegafur-uracil as compared to substitution of antiandrogen or adding antiandrogen to LH-RH analogue alone. We also examine clinical significance of mRNA expression levels of key enzymes which are involved with 5-FU metabolism as a predictive factor for this combination therapy.

Results

Fifty-two patients were enrolled in this study. Median age was 77 (47-92) years old. PSA response rate in group B (61.5%) tended to be higher than that in group A (34.6%) (p=0.0950). Group B (15.9 months) had significantly longer median time to PSA progression (TTP) than group A (6.4 months) (p=0.0137). In group B, patients with low TS (81.8%) tended to have higher PSA response rate than those with high TS (46.2%). In addition, among the patients with low TS, group B have shown significantly longer TTP than group A (p=0.0175). There were no severe AEs in both treatment groups.
