Comparison of post-implant dosimetrics between intraoperatively built custom-linked seeds and loose seeds by sector analysis at 24 hours and 1 month for localized prostate cancer

A review on permanent implants for prostate brachytherapy with comparison between stranded and loose seeds

A systematic literature review to validate the conclusions with regard to stranded seeds versus loose seeds. Published data for this review were identified by searching the PubMed databases. PD90, PV100, PV150, UD30, and RV100 acquired during the perioperative period and the postoperative period were analyzed by meta-analysis. Based on these studies, in addition to the reduction of migration and displacement, stranded seeds had some dosimetric advantages, especially in dose homogeneity and coverage of target area due to its connection characteristics. We also noticed implanted seeds usually excessive both in stranded seeds group and loose seed group. Intraoperatively built custom links will prolong operation time, with the proficiency of technology, the prolonged time gradually decreases.
