The Value of Prostate MRI with Endorectal Coil in Detecting Seminal Vesicle Involvement in Patients with Prostate Cancer
BACKGROUND In prostate cancer, detection of seminal vesicle involvement is important because it influences the treatment planning and prognosis of the patients. OBJECTIVES The objective of this study was to determine the value of prostate MRI with endorectal coil in the detection of seminal vesicle involvement in patients with prostate cancer. PATIENTS AND METHODS A total number of 238 biop...
متن کاملSeminal vesicle interfraction displacement and margins in image guided radiotherapy for prostate cancer
BACKGROUND To analyze interfraction motion of seminal vesicles (SV), and its motion relative to rectal and bladder filling. METHODS AND MATERIALS SV and prostate were contoured on 771 daily computed tomography "on rails" scans from 24 prostate cancer patients undergoing radiotherapy. Random and systematic errors for SV centroid displacement were measured relative to the prostate centroid. Mar...
متن کاملThe Role of Endorectal Magnetic Resonance Imaging in Predicting Extraprostatic Extension and Seminal Vesicle Invasion in Clinically Localized Prostate Cancer
PURPOSE We aimed to assess the clinical value of endorectal magnetic resonance imaging (MRI) in predicting extraprostatic extension and seminal vesicle invasion in patients with clinically localized prostate cancer. MATERIALS AND METHODS A total of 54 patients who underwent radical prostatectomy for clinically localized prostate cancer were retrospectively analyzed. The findings of endorectal...
متن کاملOptimal contouring of seminal vesicle for definitive radiotherapy of localized prostate cancer: comparison between EORTC prostate cancer radiotherapy guideline, RTOG0815 protocol and actual anatomy
BACKGROUND Intermediate- to-high-risk prostate cancer can locally invade seminal vesicle (SV). It is recommended that anatomic proximal 1-cm to 2-cm SV be included in the clinical target volume (CTV) for definitive radiotherapy based on pathology studies. However, it remains unclear whether the pathology indicated SV extent is included into the CTV defined by current guidelines. The purpose of ...
متن کاملO-14: Effect of Kisspeptin on Testicular Tissue and Accessory Sex Glands, Seminal Vesicle and Prostate, in Prepubertal Rats
Background: Hypothalamus-derived kisspeptins are critical regulators of reproduction in nearly all mammalian species including the humans. These small peptides mediate their actions through the GnRH loop system. How kisspeptins regulate gonadal maturation in sexually immature male mammals remains elusive. To address this, kisspeptin was administered as subchronic (12 days) twice daily i. p. dos...
