Comparative StudyImmunomagnetic quantification of circulating tumor cells as a prognostic factor of androgen deprivation responsiveness in patients with hormone naive metastatic prostate cancer.
We determined whether circulating tumor cells predict prostate specific antigen failure in patients with metastatic prostate cancer before endocrine therapy and compared their prognostic ability with other clinical factors. ⋯ In this study the presence of 5 or more circulating tumor cells in 7.5 ml blood was associated with androgen deprivation responsiveness in patients with metastatic prostate cancer before endocrine therapy.

Risk factors for recurrent ureteropelvic junction obstruction after open pyeloplasty in a large pediatric cohort.
Recurrent ureteropelvic junction obstruction after open pyeloplasty is a serious complication for which treatment remains challenging. We identified risk factors for persistent obstruction. ⋯ In this series lack of retrograde pyelography and dorsal lumbotomy were independently associated with a higher risk of recurrent ureteropelvic junction obstruction. While retrograde pyelography or a flank approach could not be directly shown to prevent recurrent ureteropelvic junction obstruction, electing to perform retrograde pyelography may be a proxy for better perioperative planning, including the choice of incision, and it may ultimately increase the chances of successful pyeloplasty.
