Squamous Cell Carcinoma Antigen (SCC)

Squamous cell carcinoma antigen (SCC) is a so-called tumor marker.Tumor markers are substances produced naturally in the body by tumors and are detectable in the blood. They can provide an indication of a malignant (malignant) neoplasm and are used as a follow-up test in cancer aftercare.

The procedure

Material needed

  • Blood serum

Preparation of the patient

  • Not necessary

Disruptive factors

  • None known

Normal value

Normal value adults <5 μg/l

Indications

  • Suspected cervical carcinoma (cervical cancer).
  • Suspicion of bronchial carcinoma (lung cancer).
  • Suspicion of other carcinomas such as esophageal carcinoma (esophageal cancer) or malignant (malignant) tumors in the area of the neck
  • Progress and therapy control in the above-mentioned tumors.

Interpretation

Interpretation of increased values

  • Anal canal carcinoma (anal cancer)
  • Bronchial carcinoma (lung cancer; detectable in 5-75% of cases, depending on histology).
  • Neoplasms in the area of the neck
  • Esophageal cancer (cancer of the esophagus; detectable in up to 40% of cases).
  • Cervical carcinoma (cervical cancer; detectable in 40-80% of cases).
  • Renal insufficiency (detectable in 20-70% of cases).
  • Psoriasis (detectable in 80% of cases).
  • Eczema (detectable in 80% of cases).

Interpretation of lowered values

  • No diagnostic significance

Further notes

  • Marker of choice in squamous cell carcinoma of the cervix.
  • Marker of choice in squamous cell carcinoma of the lung (highest sensitivity (percentage of diseased patients in whom the disease is detected by use of the test, i.e., a positive test result occurs) of all markers)
  • Elevated levels may also be detected in benign (benign) diseases of the lung, liver, pancreas, and gastrointestinal tract.
