Our data indicated that PCMT1 expression was positively related to the clinical stage of ovarian cancer (P = 0.0386) and metastatic tumor size (P = 0.0466), whereas it was not correlated with patient age (P = 0.7175), primary tumor size (P = 0.7677), or tumor histology type (P = 0.3455) (Table 1). Here, PCMT1 is linked to metastatic neoplasm.
