Serum trace elements in diagnosis of breast malignancy

Area of Science:

• Biochemistry
• Oncology
• Analytical Chemistry

Background:

• Breast cancer is a global health concern with increased risk in postmenopausal women.
• The heterogeneity of breast cancer necessitates novel diagnostic approaches.
• Investigating serum trace elements and biomarkers is crucial for early detection.

Purpose of the Study:

• To evaluate the role of serum trace elements (cadmium, cobalt, copper, zinc) in breast cancer diagnosis.
• To identify potential protein biomarkers using gel electrophoresis.
• To compare trace element levels in breast cancer patients versus control groups.

Main Methods:

• Serum trace element levels were quantified using atomic absorption spectrophotometry.
• Protein patterns were analyzed via sodium dodecyl polyacrylamide gel electrophoresis (SDS-PAGE).
• Study included 23 stage III breast cancer patients.

Main Results:

• Significantly lower mean serum levels of cadmium, copper, and cobalt were observed in breast cancer patients compared to controls.
• Zinc levels showed no significant difference in menstruating women but were decreased in premenopausal and postmenopausal patients.
• A decreased copper/zinc ratio and the appearance of specific peptide bands (33, 52, 185 kDa) were noted in patients.

Conclusions:

• Serum trace element levels are significantly altered in breast cancer patients.
• Further research is needed to elucidate the mechanisms behind these trace element alterations.
• Gel electrophoresis shows potential for identifying breast cancer biomarkers for diagnosis and treatment monitoring.
