Intraarterial adriamycin and lipiodol for inoperable hepatocellular carcinoma: a comparison with intravenous adriamycin

The technique of ‘targeting’ cytotoxic drugs by mixing them v&b the contrast medium lipiodal is now u+dely used in Japan and the Fat East where it has been reported to enhance respa~~e rates in patients with hepatocelbdar carcinoma. In the present study 19 patiettts with this tummtr were treated with iatra-@epatic)artetial adriamycb? (60 mp/m*), at least one course ofwbich was combined with lipiodol (IO-20 ml).

All other patients had B serum bilirubin conmntntion of below 60 ~molll (reference range less than 20 ~mobl), and recaived the full calculated dose of drug. The treatment protocol for those receiving the drug by the imxaanerial route (as ioitially derieed for pharmacakinetic studies) was that each patient would receive two courses of therapy; either adriamydn alone (adm), and then 3 weeks later, adriamycin mixed with lipiodol (adml lip), or vice versa. Four patients subsequently received a third ~wse comprising ad&my&, lipicdol and umgra fir! (adm/lip/uro). This report concerns those 19 patient: who received adriamycin and lipicdol, and excludes four patients who died of progressive disease shortly after their ftrst, ‘adriamycin alone’ treatment, i.e., before receiving the amme combined with lipiodol. A full blocif count, including haemogtobin concentmtion, total white cell cmmt and platelet cmmt, was taken immediately prior to adriamycin administration, and sub. sequently. wherever possible, on dayrl, 14 and 21.

One hundred milligrams of adriamycin was dissolved in 25 ml of normal saline (or urografin, 76%) and mixed thoroughly. When combined with lipiodol the requisite dose (60 mg/m’) was taken up in B sylinge and connected via a tube to a second syringe containing 10 ml (or, when urogmfin was used, 20 ml) of lipiodol. Immediately before administration to the patient, the two agents were extensively mixed by pumping to-and-fro between the syringes at least twenty times. Tbe hepatic artery was selectively catheter&d using the Seldinger technique and conventional rapid sequence films obtafned by injecting nonionic contrast medium. The lipiodolladriamycin mixture was then administered directly into the hepatic artery as a bolus over2 min. ConArmation that the lipiodol bad local&d to the turnour areas was obtained by computed tomography at 1 week (Fig. 1).

Stable disease was defined as a less than 50% decrease in she of the tumour as measured by Cf or less than 50% decrease in serum APP over 4 weeks. Increase in AFP levels, liver size or development of new metastasis was considered to indicate progressive disease. Response was measured from the date of the initial treatment until the time of diseirse progression. Survival time was calculated from the time of diagnosis and survival cwves were calculated using the Kaplan-Meier method (14).

The remaining 14 patients had progressive dik ease with no evidence of response to treatment. There was no significant difference in the survival curves of the two groups (Fig. 2) and the median survival was almost identical (intraarterial group, 3 months (range, l-18); intravenous group, 4 months (rrmge, 1-19)). The survival times of the responders, in both groups were greater than in the non-responders (intraarterial group: responders, 8 and 12 months, “on-responders, media” 2 months (range, I-18); intravenous group: responders 3,13 and 14 months, “on-responders, median

However, without a prospective controlled trial this is difficult to prove, particularly in view of the prolonged SWviva1 reported in patients with small turnours. Okuda et al. (20) reported survival of 90% at 1 year even in the atsence of any f%?abnenf, and it is noteworthy that in the experience of Takayasu et al. (17). on multiple regression analysis. the size of the turnour rather than any method of administration (i.e., with or without lipiodol) was the only factor influencing survival. Some authors have considered

that the use of lip&&l perse causes therapeutic embolisadon of the furnow (10.21) though this has been disputed (22).
