Lymphatic drainage in renal tumours and implications for management

Purpose: Lymphatic drainage from renal tumors is unpredictable and in vivo drainage studies ofprimary lymphatic landing sites may reveal the variability and dynamics of lymphatic connections.The purpose of this study was to investigate the lymphatic drainage pattern from renal tumors in vivo with SPECT/CT imaging after intra-tumoral radiotracer injection.Materials and methods: We conducted a phase II prospective single-arm study to investigate thedistribution of SNs from renal tumors on SPECT/CT imaging. Patients with cT1-3 (
