Correlation between SSTR2 immunoreactivity and Ki-67 labeling index (LI). (a–c) In the foregut NETs, SSTR2 was significantly inversely correlated with Ki-67 LI, especially when using the Volante scores and IRSs (p = 0.0049, ρ = −0.3709 and p = 0.0099, ρ = −0.3418, respectively). (d–f) In the midgut NETs, SSTR2 was positively correlated with Ki-67 LI, although not significantly. (g–i) In the hindgut NETs, SSTR2 was positively correlated with Ki-67 LI, especially when evaluated using the Volante scores and IRSs; the former correlation was significant (p = 0.0044, ρ = 0.3339 and p = 0.0600, ρ = 0.2244, respectively).
