Overview

Definition

  • Serum tumor Tumor Inflammation markers, usually just referred to as “ tumor Tumor Inflammation markers,” are proteins Proteins Linear polypeptides that are synthesized on ribosomes and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of amino acids determines the shape the polypeptide will take, during protein folding, and the function of the protein. Energy Homeostasis or carbohydrates Carbohydrates A class of organic compounds composed of carbon, hydrogen, and oxygen in a ratio of cn(H2O)n. The largest class of organic compounds, including starch; glycogen; cellulose; polysaccharides; and simple monosaccharides. Basics of Carbohydrates that increase due to cancer.
  • Cellular tumor Tumor Inflammation markers are also used to detect the presence of malignant cells with distinctive genetic changes.
  • Both can usually be measured in circulating cells of different body fluids and in tissues. 

Uses and limitations Limitations Conflict of Interest

Uses:

Baseline level should be established at the time of initial presentation.

  • Evaluating tumor Tumor Inflammation response to therapy (e.g., chemotherapy Chemotherapy Osteosarcoma, radiotherapy, or surgery)
  • Monitoring for tumor Tumor Inflammation recurrence (e.g., carcinoembryonic antigen Antigen Substances that are recognized by the immune system and induce an immune reaction. Vaccination (CEA) with colon Colon The large intestines constitute the last portion of the digestive system. The large intestine consists of the cecum, appendix, colon (with ascending, transverse, descending, and sigmoid segments), rectum, and anal canal. The primary function of the colon is to remove water and compact the stool prior to expulsion from the body via the rectum and anal canal. Colon, Cecum, and Appendix: Anatomy cancer)
  • Determining stage, prognosis Prognosis A prediction of the probable outcome of a disease based on a individual’s condition and the usual course of the disease as seen in similar situations. Non-Hodgkin Lymphomas, and treatment plan for certain malignancies (e.g., hCG pretreatment level included in the International Federation of Gynecology and Obstetrics (FIGO)  staging Staging Methods which attempt to express in replicable terms the extent of the neoplasm in the patient. Grading, Staging, and Metastasis system for choriocarcinoma Choriocarcinoma A malignant metastatic form of trophoblastic tumors. Unlike the hydatidiform mole, choriocarcinoma contains no chorionic villi but rather sheets of undifferentiated cytotrophoblasts and syncytiotrophoblasts (trophoblasts). It is characterized by the large amounts of chorionic gonadotropin produced. Tissue origins can be determined by DNA analyses: placental (fetal) origin or non-placental origin. Gestational Trophoblastic Disease)
  • Screening Screening Preoperative Care for cancer (e.g., prostate-specific antigen Prostate-specific antigen A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.

Limitations Limitations Conflict of Interest:

  • False positives: elevated tumor Tumor Inflammation marker but no cancer
  • False negatives: Tumor Tumor Inflammation marker is not elevated despite the presence of cancer.

Classification

  • Cellular tumor Tumor Inflammation markers
    • Indicate expression of oncogenes Oncogenes Genes whose gain-of-function alterations lead to neoplastic cell transformation. They include, for example, genes for activators or stimulators of cell proliferation such as growth factors, growth factor receptors, protein kinases, signal transducers, nuclear phosphoproteins, and transcription factors. A prefix of ‘v-‘ before oncogene symbols indicates oncogenes captured and transmitted by retroviruses; the prefix ‘c-‘ before the gene symbol of an oncogene indicates it is the cellular homolog (proto-oncogenes) of a v-oncogene. Carcinogenesis
    • Example: carbohydrate antigen Antigen Substances that are recognized by the immune system and induce an immune reaction.

Clinical manifestations include amenorrhea; galactorrhea; impotence; headache; visual disturbances; and cerebrospinal fluid rhinorrhea. Hyperprolactinemia causes an elevation in the normal secretion Secretion Coagulation Studies of prolactin Prolactin A lactogenic hormone secreted by the adenohypophysis.
