• Serum levels of circulating immunocomplexes (CIC) were studied in a group of 37 patients with laryngeal carcinoma using two polyethylene glycol—precipitation methods. The preoperative values of this group showed higher levels of CIC when compared with 140 normal controls. No correlation was noted between tumoral stage, oncotype, and serum levels of CIC. Previous studies have shown that the status of several different types of human tumors can be monitored by serial determinations of levels of CIC. We believe that this technique can be used to evaluate the efficacy of therapy and to detect the recurrence of laryngeal carcinoma.
