Comparison of distribution of timing of lymphoscintigraphy by year. Patients were divided into two cohorts (2008–2011 and 2012–2015) and the proportion of patients undergoing lymphoscintigraphy early (<12 h) was compared with late (>12 h). The results show showed a decrease in early lymphoscintigraphy rate from 40.8% to 31.6% in the second cohort (Chi squared test p = 0.002).

Comparison of OS, DSS and nodal relapse rates in early versus late treatment groups. 2A Kaplan Meier survival curve, which shows that there is a reduction in OS of 10.6% (p = 0.01, HR 1.64 [1.13–2.38]) in patients undergoing SLNB > 12 h post Tc-99 m nanocolloid injections. 2B Kaplan Meier survival curve, which shows a significant reduction (p = 0.04) in DSS in patients undergoing SLNB > 12 h post Tc-99 m nanocolloid injections. 2C Kaplan Meier survival curve which does not show any significant difference (p = 0.67) in nodal relapse rates between early versus late treatment groups.

Comparison of OS in treatment groups according to time course. OS is compared between groups patients undergoing Tc99m-nanocolloid injections 6, 9, 12 and 18 h prior to sentinel lymph node biopsy using Kaplan Meier curves. The results show a significant difference (p < 0.003) between patients undergoing early versus late lymphoscintigraphy, with the greatest difference observed at 12 h.
