Somatostatin receptor scintigraphy in the follow up of neuroendocrine neoplasms of appendix

Figure 1 Receiver operating characteristics analysis shows area under the curve of 0. 850 (95% confidence interval: 0.710-0.990, P < 001). ROC: Receiver operating characteristics; AUC: Area under the curve; CI: Confidence interval.

Figure 2 Liver metastases of carcinoid of appendix revealed with ^99mTc-Tektrotyd.

Figure 3 Liver metastases of carcinoid of appendix revealed with ⁹⁰Y-tetraxetan-tyrosine3-octreotate.

Figure 4 Median progression- free survival in somatostatin receptor scintigraphy. Median progression- free survival in somatostatin receptor scintigraphy positive patients was 52 months (95% confidence interval: 39.7-117.3) while in somatostatin receptor scintigraphy negative patients it was 60 months (95% confidence interval: 42.8-77.1), without statistically significant difference between the two groups (P = 0.434).
