In 23/75 patients without PM, no CD326(+)CD45(-) tumor cells were counted among more than 10000 live cells whereas a small number of CD326(+) cells were detected in the other 52 patients (Figure 2A left panel), and thus their TLRs were calculated as 0-0.22% (median=0.0032%). Here, PTPRC is linked to neoplasm.
