Abstract: Objective

·To investigate the expression and diagnostic value of prostate specific antigen (PSA), tumor abnormal protein (TAP) and colon cancer metastasis related gene 1 (MACC1) in the blood of patients with prostate cancer.

Methods

·One hundred and seven patients with prostate cancer (case group) admitted to Dahua Hospital, Xuhui District, Shanghai, from January 2019 to December 2020 were retrospectively analyzed, and 60 healthy people (control group) who underwent physical examination in the hospital in the same period were selected. The levels of blood PSA, TAP and MACC1 in the two groups, as well as their correlation with Gleason score and T stage, were analyzed. Receiver operating characteristic (ROC) curve was used to evaluate the value of various indexes in the diagnosis of prostate cancer.

Results

·The levels of blood PSA, TAP and MACC1 in the case group were significantly higher than those in the control group (P<0.05). With the increase of Gleason grade, the levels of blood PSA, TAP and MACC1 increased gradually. With the progress of T stage, the levels of blood PSA, TAP and MACC1 increased gradually. The levels of PSA and MACC1 in the patients with lymph node metastasis were significantly higher than those without lymph node metastasis, but the levels of TAP in the patients with lymph node metastasis were significantly lower than those without lymph node metastasis (P<0.05). The analysis results of ROC curve showed that the AUC of PSA in the diagnosis of prostate cancer was 0.764, the sensitivity was 86.12%, the specificity was 88.63%, and the cut-off value was 6.01 μg/L. The AUC of TAP in the diagnosis of prostate cancer was 0.796, the sensitivity was 88.18%, the specificity was 89.58%, and the cut-off value was 135.62 μm2. The AUC of MACC1 in the diagnosis of prostate cancer was 0.873, the sensitivity was 78.46%, the specificity was 80.10%, and the cut-off value was 37.80 pg/mL. The AUC (0.941), sensitivity (93.15%) and specificity (94.08%) of combined detection were higher than those of any single detection (P<0.05). Spearman correlation analysis showed that the blood PSA, TAP and MACC1 levels were positively correlated with Gleason score (r=0.648, 0.513, 0.501; P=0.000), and with T stage (r=0.616, 0.537, 0.542; P=0.000).

Conclusion

·Blood PSA, TAP and MACC1 are closely related to Gleason score and T stage of prostate cancer, which has some value in the diagnosis of prostate cancer, and the combined detection of three items has higher diagnostic value.
