Ultrasonographic evaluation of depth-width ratio (D/W) of benign and malignant mammary tumors in dogs.

Tagawa M, Kanai E, Shimbo G, Kano M, Kayanuma H - J. Vet. Med. Sci. (2015)

Bottom Line: Results of ultrasonographic and histopathologic examinations were compared.The D/W of malignant tumors was significantly greater than that of benign tumors, and it had a sensitivity of 56.3% and a specificity of 92.9% for the diagnosis of malignancy when the threshold of D/W was 0.7.In addition, irregular margin, polymorphous shape and heterogeneous internal echographic characteristics were correlated with malignancy.

ABSTRACT
Depth-width ratio (D/W) is the only quantitative item in the criteria recommended by the Japanese Ultrasound Society for the evaluation of breast tumors in humans. However, the usefulness of the D/W has not been evaluated in dogs. Eighty-six mammary masses in 34 female dogs underwent ultrasonographic examination to determine the D/W and other characteristics. Results of ultrasonographic and histopathologic examinations were compared. The D/W of malignant tumors was significantly greater than that of benign tumors, and it had a sensitivity of 56.3% and a specificity of 92.9% for the diagnosis of malignancy when the threshold of D/W was 0.7. In addition, irregular margin, polymorphous shape and heterogeneous internal echographic characteristics were correlated with malignancy.

Mentions: Box plots of the D/W of 86 mammary masses in 34 dogs. The box represents theinterquartile range (i.e., 25–75th percentile range or the middle half of the box). Thehorizontal bar in the box represents the median value. For both box plot, the T-barsrepresent the 5 to 95 percentile range. Outlying data points are represented by blackdots.
