ABSTRACT
Objective:
To analyze the ultrasonographic images and clinical characteristics of congenital mesoblastic nephroma (CMN), and to investigate the differential performances with Wilm′s tumor (WT).Methods:
Twenty-one cases of CMN patients confirmed by pathology from December 2008 to December 2019 in Beijing Children′s Hospital, Capital Medical University were collected as the CMN group, and in the same criterion, 51 cases of WT patients were taken as WT group. Ultrasonographic images and clinical characteristics were collected retrospectively, and then the tumor size, site, echo and age were compared and analyzed between the two groups. ROC curve was used to evaluate the differential performance.Results:
The difference analysis showed that except for echo ( P=0.694), there were statistically significant differences in tumor size, site and age between the two groups (all P<0.05). In prenatal, the incidence of CMN was significantly higher than WT (61.9% vs 3.9%, P<0.001), and the specificity was 96.1%. The median age (interquartile range) of CMN after birth was significantly earlier than WT( Z=-4.044, P<0.001). The area under the ROC was 0.949, the best cutoff was 112.5 days, with a sensitivity of 87.5% and a specificity of 93.9%.Conclusions:
It is difficult to distinguish CMN and WT by echo, but the diagnosis performance can be improved through combining tumor size with site, especially age.
