Intra-arterial lipiodol labeled with iodine 131 ((131)I-lipiodol) can be safely used as adjuvant therapy following curative liver resection for hepatocellular carcinoma (HCC). ⋯ This pilot study failed to demonstrate any clinically significant adverse effect of adjuvant therapy by intra-arterial (131)I-lipiodol after curative liver resection for HCC. Long-term survival compares favorably with those undergoing only surgery and suggests a benefit in lowering tumor recurrence. A randomized, multicenter, prospective trial comparing patients treated with intra-arterial (131)I-lipiodol with a nontreated control group seems appropriate.

A shift in the balance of helper T cells type 1 (T(H)1) toward type 2 (T(H)2) has been suggested as a possible mechanism for impaired immune responses after severe trauma. We suggest that major injuries (polytrauma) induce an alteration in the pattern of T(H)1/T(H)2 cells. ⋯ Patients with multiple injuries have no significant alteration in the ratio of circulating T(H)1/T(H)2 cells. Thus, our results suggest pathomechanisms in posttraumatic T-cell suppression apart from alterations in the T(H)1/T(H)2 pattern.
