MKI67 and carcinoid tumor: Table 2 shows the relationship between various factors (carcinoid type, size, and mitosis and Ki-67 index) and metastasis at various levels. The sensitivity, specificity, odd ratio, and P value were calculated. As expected there is a statistically significant correlation between metastasis and carcinoid type (P = 0.039) and mitoses ≥2 (P = 0.017) with relatively high specificity.
