GPC6 and neoplasm: Significant correlations with post-surgical lymphnodal metastases were further disclosed between gender (p = 0.043), the presence of precancerous lesions (p = 0.003; Figure 4), the occurrence of lymphnodal infiltration at time of surgery (p = 0.001), stromal expression of SDC2 (p = 0.015; Figure 4) and altered GPC6 protein expression in tumour cells (p = 0.01; Table 3).
