Serum tumour markers in clinical practice. Some general aspects
1Department of Oncology, University Hospital of Trondheim, Norway.
Summary
Serum tumour markers have limited use in screening but can aid in diagnosis and prognosis for some cancers. Their greatest value lies in assessing therapy effectiveness in advanced diseases, requiring further clinical trials.
Area of Science:
- Oncology
- Clinical Diagnostics
Background:
- Serum tumour markers are widely discussed for clinical applications.
- Their utility is constrained as marker production is not exclusive to malignant cells or phenotypes.
Purpose of the Study:
- To discuss the current role and limitations of serum tumour markers in clinical practice.
- To evaluate their diagnostic, prognostic, and therapeutic assessment value.
Main Methods:
- Review of general aspects of serum tumour markers in clinical practice.
- Analysis of marker production specificity and connection to malignant phenotype.
Main Results:
- Serum tumour markers are unsuitable for cancer screening.
- They offer diagnostic value in specific clinical scenarios and prognostic value in select malignancies.
- The assessment of therapy in advanced disease represents their most significant, yet underexploited, application.
Conclusions:
- Serum tumour markers are not recommended for screening purposes.
- Their diagnostic and prognostic utility is context-dependent.
- Further validation through prospective, randomized clinical trials is essential to determine their true importance, especially in therapy assessment.
