Are elevated serum levels of type I collagen degradation marker ICTP and tissue inhibitor of metalloproteinase ( TIMP ) 1 associated with poor prognosis in lung cancer?
Our results indicated that ICTP and TIMP-1 are good prognostic markers in lung cancer. The association between serum MMP-9 and ICTP suggests that MMP-9 could play a role in the degradation of the extracellular matrix producing ICTP in this pathological situation.
Suicidal hanging is a relatively rare cause of death for potential organ donors. Because it does not appear to negatively affect outcomes after LTx, it should not be considered per se a contraindication for lung donation. A word of caution is necessary until we gather larger experience with lungs from hanging donors.
