Abstract:
Objective To investigate MRI characteristics of recurrent prostate cancer after endocrinotherapy.Methods Recurrent prostate cancer after endocrinotherapy was diagnosed clinically in 10 cases.MRI examinations were performed before and after recurrence of tumors.T_2 signal intensity and morphological changes of the prostate,involvement of pelvic tissues,metastasis of bone and lymph metastasiswere analyzed.Results The prostates enlarged in 7 patients after recurrence and maintained the same size in the other three.The pelvictissues,including seminal vesicle,bladder,rectal and obturator internus,were involved in 7 patients after recurrence.Metastasis of bone and lymph node progressed in 7 and 9 patients,respectively,but T_2 signal differences were unremarkable between recurrent regions and otherregions.Conclusion MRI examination can provide sufficient radiologic information in the diagnosis of recurrence of prostate cancer afterendocrinotherapy.
