title: Defective neutrophil mobilization to skin chambers in cancer patients.
abstract: The in vivo migration of neutrophils was evaluated in patients affected by epithelial carcinoma using the quantitative skin-chamber technique. The results demonstrated a significant impairment of the patients' neutrophil migration, which was reduced to approximately 4% of that of the controls. Patients' sera were able to inhibit the chemotactic responsiveness of normal neutrophils in vitro. It is therefore suggested that the defective in vivo migration of neutrophils in cancer patients is related to the presence of humoral cell-directed inhibitory activity. This defect of neutrophil function might contribute to the host-defense impairment of carcinoma patients.
