Summary
Prostate cancer differentiation grade impacts serum tumor marker levels. Higher levels of acid phosphatase (ACP) and prostate specific antigen (PSA) were observed in moderately differentiated tumors, aiding in cancer staging.
Area of Science:
- Urology
- Oncology
- Biochemistry
Background:
- Prostate cancer is a significant health concern.
- Accurate staging is crucial for effective treatment.
- Tumor markers can aid in diagnosis and prognosis.
Purpose of the Study:
- To investigate the relationship between histological differentiation grade of prostate cancer and serum levels of tumor markers.
- To determine if serum acid phosphatase (ACP), prostate specific phosphatase (PAP), and prostate specific antigen (PSA) levels correlate with tumor grade and metastatic status.
Main Methods:
- Serum levels of ACP, PAP, and PSA were measured in 100 prostate cancer patients.
- Patients were categorized into differentiation grades: G1 (well), G2 (moderately), and G3 (poorly differentiated).
- Bone metastases were assessed using scintigraphy.
Main Results:
- In non-metastatic (M0) patients, mean levels of all three markers were slightly higher in the G2 group compared to G1.
- In metastatic (M1) patients, G2 tumors showed significantly higher serum ACP and PAP levels than G3 tumors.
- A trend of higher marker levels in G2 was observed in both M0 and M1 cases.
Conclusions:
- Histological differentiation grade significantly affects serum levels of prostate tumor markers.
- Serum marker levels, particularly ACP and PAP, can provide additional information for staging prostate cancer.
- These findings may enhance clinical practice in managing prostate cancer patients.
