Collaborative Stage

Collaborative Stage for TNM 7 - Revised 11/12/2010 [ Schema ]

CS Site-Specific Factor 6
Lactate Dehydrogenase (LDH)

Note 1: Lactate dehydrogenase (LDH) is an enzyme that is released into the bloodstream when cells are damaged or destroyed. Cancer cells have a high rate of turnover, leading to an elevated LDH. An elevated LDH is a generic marker of injury to cells and not specific to cancer.
Note: Record the range of LDH value as documented in the patient record at the time of diagnosis.

025	5.1-10 x N (Between 5.1 and 10 times the upper limit of normal for LDH)
030	Greater than 10 x N (Greater than 10 times the upper limit of normal for LDH)
