AbstractThe systemic side effects of isolated limb perfusion (ILP) with rhTNF alpha and melphalan are characterised by the induction of a systemic inflammatory response syndrome (SIRS). Procalcitonin (PCT), a serum marker of bacterial sepsis, was investigated with respect to its role in SIRS after TNF-ILP. Serum-PCT was analysed in 24 patients (12 male, 12 female), who treated by ILP for regionally metastasized melanoma (n = 8) or locally advanced soft tissue sarcoma (n = 16). Serum samples were analysed pre- and intraoperatively, and at defined intervals after reperfusion of the limb. In addition to PCT, serum IL-6 and IL-8 were analysed in 11 patients. PCT was significantly elevated over baseline after ILP with a maximum between 8 and 36 hours (p < 0.001). Even 96 hours after reperfusion, PCT was still significantly elevated as compared to baseline levels (p = 0.005). There was no correlation to the systemic leakage rate during the perfusion. IL-6 and IL-8 were also significantly increased after ILP (p = 0.001), but the maximum peaks of both cytokines were reached much earlier than for PCT (IL-8 max. at 1 hour and IL-6 max. at 4 hours after reperfusion). Serum procalcitonin is induced as part of the specific SIRS after ILP with rhTNF alpha and melphalan. It may be induced directly by rhTNF alpha or by different cytokines, as serum peaks of IL-6 and IL-8 are reached well before the peak of PCT. Determination of PCT prior to and after ILP with TNF might be useful to assess patients at risk of developing hyperdynamic shock.
