Biochemical markers in human breast cancer

Area of Science:

• Biochemistry
• Oncology
• Medical Diagnostics

Background:

• Breast cancer diagnosis and staging rely on various methods.
• Biochemical markers are individually explored for their potential in breast cancer detection.
• Accurate assessment of metastatic disease and prognosis is crucial for treatment planning.

Purpose of the Study:

• To evaluate the utility of nineteen biochemical parameters as potential tumor index substances for breast cancer.
• To identify which biochemical markers are most effective in detecting overt metastases.
• To assess the predictive value of these markers for disease relapse.

Main Methods:

• Measurement of nineteen biochemical parameters in 51 patients with breast disease, including 42 with active breast cancer.
• Analysis of marker levels in patients with overt metastases and those with poor prognostic indicators.
• Comparison of biochemical detection rates with physical methods for metastases.

Main Results:

• Seven parameters (serum ferritin, C-reactive protein, carcinoembryonic antigen, acid glycoprotein, total alkaline phosphatase, sialyl transferase, urinary hydroxyproline/creatinine ratio) were elevated in over half of patients with overt metastases.
• Biochemical abnormalities showed favorable incidence compared to physical methods for detecting metastases.
• Abnormalities in at least one of the seven markers were found in 7 of 16 patients with poor prognosis but no distant metastases; 3 of these relapsed within a year.

Conclusions:

• Specific biochemical tests demonstrate significant potential in monitoring metastatic breast cancer.
• These markers can help identify patients at high risk for relapse at the time of mastectomy.
• Biochemical monitoring may guide decisions for immediate systemic therapy in addition to local treatment.
