Abstract Objective: To explore the correlation between molybdenum target X-ray and CUES expression in early DCIS and immunohistochemical HER-2 and nm-23 expression. Methods: A total of 80 cases of DCIS patients admitted from January 2018 and January 2020 were retrospective selected as the research object. Expression levels of immunohistochemical HER-2 and nm-23 were detected and image data were collected, which were analyzed with Spearman. Results: Among the 80 patients, there were 36 cases with high expression of HER-2, 44 cases with low expression of HER-2, 38 cases with high expression of nm-23, and 42 cases with low expression of nm-23 by immunohistochemistry. Abnormal vascular distribution, non-centric enhancement, high enhancement, non-uniform enhancement, and PI in the high HER-2 expression group were significantly higher than those in the low HER-2 expression group (P<0.05), and TTP in the high HER-2 expression group was significantly lower than that in the low HER-2 expression group (P<0.05). The proportion of non-radioactive enhancement and TTP in the high expression group of nm-23 were significantly higher than those in the low expression group of nm-23 (P<0.05), while PI was significantly lower than that in the low expression group of nm-23 (P<0.05). High expression of HER-2 was positively correlated with TTP (P<0.05), and negatively correlated with PI (P<0.05). High expression of nm-23 was negatively correlated with TTP (P<0.05), and positively correlated with PI (P<0.05). Conclusion: The characteristics of moly target X-ray and CUES are correlated with the expression levels of immunohistochemical HER-2 and nm-23, and abnormal vascular distribution, enhanced centrality, high enhancement, radial enhancement, high TTP and low PI should be suspected to be high HER-2 expression, while low TTP and high PI should be suspected to be high nm-23 expression.
