Longitudinal magnetic resonance imaging-based assessment of vascular changes and radiation response in androgen-sensitive prostate carcinoma xenografts under androgen-exposed and androgen-deprived conditions.

Abstract:

:Prostate cancer (PCa) patients receive androgen-deprivation therapy (ADT) to reduce tumor burden. However, complete eradication of PCa is unusual, and recurrent disease is evident within approximately 2 years in high-risk patients. Clinical evidence suggests that combining ADT with radiotherapy improves local control and disease-free survival in these patients compared with radiotherapy alone. We investigated whether vascularization of androgen-sensitive PCa xenografts changed after ADT and whether such therapy affected radiation response. CWR22 xenografts received combinations of ADT by castration (CWR22-cas) and 15 Gy of single-dose irradiation. At a shortest tumor diameter of 8 mm, vascularization was visualized by dynamic contrast-enhanced magnetic resonance imaging before radiation and 1 and 9 days after radiation. Voxel-wise quantitative modeling of contrast enhancement curves extracted the hemodynamic parameter K(trans), reflecting a combination of permeability, density, and blood flow. Tumor volumes and prostate-specific antigen (PSA) were monitored during the experiment. The results showed that K(trans) of CWR22-cas tumors 36±4 days after ADT was 47.1% higher than K(trans) of CWR22 tumors (P = .01). CWR22-cas tumors showed no significant changes in K(trans) after radiation, whereas K(trans) of CWR22 tumors at day 1 decreased compared with pretreatment values (P = .04) before a continuous increase from day 1 to day 9 followed (P = .01). Total PSA in blood correlated positively to tumor volume (r = 0.59, P < .01). In conclusion, androgen-exposed xenografts demonstrated radiation-induced reductions in vascularization and tumor volumes, whereas androgen-deprived xenografts showed increased vascularization and growth inhibition, but no significant additive effect of radiation.
