As shown in Table 1 and Fig. 4b, CCR3 expression was positively correlated with Gleason score, the size of the undifferentiated component (percentage of tumour classified as Gleason 4 or 5), localization at the peripheral zone of the prostate gland, local extension of the prostate cancer (shown by pT stage), the presence of lymphatic emboli and biochemical recurrence (BCR). This evidence concerns the gene BCR and prostate carcinoma.
