PTPRC and endometrium neoplasm: Table 1 presents the demographic information of the 72 patients who participated in the study. Table 2A shows the histology of the tumors from the patients with endometrial tumors, and Table 2B presents the pathological parameters of the patients. Endometrial CAMLs were identified in 7.5 mL of a patient’s blood sample at the time of surgery. The identification was based on the CD45+/CK 8,18,19+/CD31+/EpCAM+ immunofluorescent stains with the DAPI+ nuclear morphology of macrophages (Figure 1).
