Ketoconazole Treatment, PSA Response, and Disease Progression
Parameter | Value |
---|---|
Follow-up time (months): mean ± SD (range); median | 40.1 ± 27.4 (5–129); 31 |
Ketoconazole dose | |
200 mg thrice daily dosage (tid) | 32% (n = 36) |
200 mg tid subsequently increased to 400 mg tid | 40% (n = 46) |
400 mg tid | 28% (n = 32) |
PSA response | |
PSA decrease (%) in the whole group: mean ± SD (range); median | 29 ± 81.5% (−400 to 99.9); 53% |
Patients with PSA decrease ≥50% in the whole group | 54% (n = 61) |
PSA decrease ≥50% in patients with limited vs. extensive disease | 84% (n = 32/38) vs. 36% (n = 27/76), OR 9.1, P < 0.001 |
PSA decrease ≥50% in patients with pretreatment PSADT ≥3 vs. <3 | 62% (n = 31/50) vs. 44% (n = 28/64), OR 0.49, P = 0.01 |
Patients with PSA decrease <50% | 21% (n = 24) |
Patients refractory to treatment | 25% (n = 29) |
Time to progression (months): mean ± SD (range), median | |
Whole group | 12.8 ± 17.1 (1–129), 8 |
In patients with limited vs. extensive disease | 20.2 ± 23.4 (1–129), 14 vs. 9.1 ± 11.3 (1–74), 5 |
In patients with prior response to antiandrogen ≥6 vs. <6 months | 18.8 ± 11 (3–129), 18.5 vs. 6.5 ± 11.9 (1–74), 4 |
In patients with pretreatment PSADT ≥3 vs. <3 months | 17.9 ± 23 (1–129), 12 vs. 8.8 ± 9.4 (1–47), 5 |
