Abstract:
Objective To compare the value of (~99m) Tc-octreotide scintigraphy and planar X-ray mammography in the diagnosis of breast cancer. Methods A total of 32 patients with suspected breast cancer were enrolled into this study. All patients underwent (~99m) Tc-octreotide scintigraphy and planar X-ray mammography. The diagnostic efficiency of (~99m) Tc-octreotide scintigraphy and planar X-ray mammography were compared based on the post-surgery pathology. Results The sensitivity of (~99m) Tc-octreotide scintigraphy and planar X-ray mammography in the diagnosis of breast cancer was 91.67% and 66.67%, the specificity was 100% and 37.50%, the accuracy was 93.75% and 59.38%, respectively. Combining (~99m) Tc-octreotide scintigraphy with planar X-ray mammography, the sensitivity, specificity, accuracy, positive predicting values and negative predicting values for breast cancer was 95.83%, 100%, 96.88%, 82.14% and 47.06%, respectively. Conclusion The diagnostic efficiency of (~99m) Tc-octreotide scintigraphy for breast cancer is superior to planar X-ray mammography. (~99m) Tc-octreotide scintigraphy combined with planar X-ray mammography, the diagnostic efficiency for breast cancer will be further improved.
