Summary
Serum enzyme analysis is not effective for early colon cancer detection. However, specific enzymes can help monitor disease progression, especially liver metastasis, and aid in understanding colon cancer causes.
Area of Science:
- Biochemistry
- Oncology
- Gastroenterology
Background:
- Serum enzyme levels are generally not useful for diagnosing early colon cancer.
- Certain enzymes show promise in monitoring disease progression, particularly in cases of liver metastasis.
Purpose of the Study:
- To evaluate the utility of enzyme analysis in colon cancer management.
- To explore enzyme patterns in biopsy specimens, feces, and colon washings for diagnostic potential.
- To investigate the etiological factors of colon cancer through enzyme activity.
Main Methods:
- Review of studies examining enzyme patterns in various biological samples (biopsy, feces, washings).
- Analysis of specific enzyme activities including transpeptidase, phosphohexone isosomerase, 5'-nucleotidase, aryl sulfatase, beta-glucuronidase, beta-glucosidase, lactic dehydrogenase, and glucose-6-phosphate dehydrogenase.
- Consideration of technical challenges in human enzyme assays.
Main Results:
- Serum enzymes lack diagnostic value for early colon cancer.
- Specific enzymes (e.g., transpeptidase, phosphohexone isosomerase, 5'-nucleotidase) aid in tracking disease course, especially with liver metastasis.
- Enzyme pattern analysis in biopsy specimens, feces, and washings shows potential for diagnostic tools and etiological research.
Conclusions:
- While serum enzymes are not effective for early diagnosis, specific enzyme markers can monitor colon cancer progression and liver involvement.
- Further research into enzyme patterns in various samples may lead to novel diagnostic tools and a better understanding of colon cancer etiology.
