Biomarkers of Prostatic Cancer: An Attempt to Categorize Patients into Prostatic Carcinoma, Benign Prostatic Hyperplasia, or Prostatitis Based on Serum Prostate Specific Antigen, Prostatic Acid Phosphatase, Calcium, and Phosphorus

Table 6

The PSA levels and staging of prostate carcinoma patients.

Age (years)	Number of patients	PSA (ng/mL)	TNM staging	Stage	Gleason score
50–59			T1N0 M0	I-II
60–69			T1N1 M0	II-III
70–79			T3N1 M1	III-IV
			T3NXM1	III-IV
			T2N0 M1	I-II

The table showed the TNM (tumor, lymph nodes, and metastases) staging and Gleason score in patients of various age groups. The level of PSA was also included.
