| tumor marker | <investigation, oncology> A substance in the body that usually indicates the presence of cancer. These markers are usually specific to certain types of cancer and are usually found in the blood or other tissue samples. Examples are alphafetoprotein (AFP), human chorionic gonadotropin, and lactate dehydrogenase (LDH). They may be indicators of tumour stage and grade as well as useful for monitoring responses to treatment and predicting recurrence. Many chemical groups are represented including hormones, antigens, amino and nucleic acids, enzymes, polyamines, and specific cell membrane proteins and lipids. (18 Jul 2002) |

| linkage marker | A locus at which there is a high probability of heterozygotes (indispensible state for linkage analysis), but in itself perhaps of no clinical interest. See: marker locus. (05 Mar 2000) |
| receptors, cell surface | Cell surface proteins that bind signalling molecules external to the cell with high affinity and convert this extracellular event into one or more intracellular signals that alter the behaviour of the target cell. Cell surface receptors, unlike enzymes, do not chemically alter their ligands. (12 Dec 1998) |
| SP220K cell surface matrix proteinase | <enzyme> Inactive form has guanidinobenzoatase activity; active form has gelatinolytic activity Registry number: EC 3.4.21.- Synonym: sp220k enzyme (26 Jun 1999) |
| T-cell-rich, B-cell lymphoma | <tumour> A B-cell lymphoma in which more than 90% of the cells are of T-cell origin, masking the large cells that form the neoplastic B-cell component. See: adult T-cell lymphoma. (05 Mar 2000) |
| acromial articular surface of clavicle | A small oval facet on the lateral end of the clavicle for articulation with the acromion. Synonym: facies articularis acromialis claviculae, acromial articular facies of clavicle. (05 Mar 2000) |
| anterior part of diaphragmatic surface of liver | The part of the diaphragmatic surface of the liver deep to the costal arches and the xiphoid process. Synonym: pars anterior faciei diaphragmatis hepatis. (05 Mar 2000) |
| anterior surface | The surface of a structure or part of the body that faces forward. Synonym: facies anterior. (05 Mar 2000) |
| anterior surface of arm | Anterior articular surface of dens, the curved articular facet on the anterior aspect of the dens of the axis that articulates with the facet for the dens of the axis anterior arch of the atlas. Synonym: facies articularis anterior dentis. (05 Mar 2000) |
| anterior surface of cornea | The external surface of the cornea. Synonym: facies anterior corneae. (05 Mar 2000) |
| anterior surface of elbow | The area in front of the elbow, including the cubital fossa. Synonym: facies cubitalis anterior, regio cubitalis anterior, anterior cubital region, anterior surface of elbow. (05 Mar 2000) |
| anterior surface of eyelids | anterior surface of eyelids |
| anterior surface of forearm | Synonym: anterior region of forearm. (05 Mar 2000) |
| anterior surface of iris | The anterior surface of the iris of the eye. Synonym: facies anterior iridis. (05 Mar 2000) |
