A standard dose of Adriamycin (60 mg m-2) was administered to 30 patients with inoperable hepatocellular carcinoma, 16 of whom were hyperbilirubinaemic (18-37 mumol l-1). The hyperbilirubinaemic patients experienced marked myelosuppression, but only minor symptomatic side-effects. The degree of neutropenia was directly related to the serum bilirubin concentration, but not to any other standard liver test, presence or absence of cirrhosis, or any pharmacokinetic parameter studied including the area under the Adriamycin or adriamycinol concentration-time curve to 48 h or infinity, or the terminal half-life of Adriamycin. The area under the log concentration-time curve was significantly greater for both Adriamycin and adriamycinol in patients who were hyperbilirubinaemic compared to those with normal bilirubin. Whilst hyperbilirubinaemic patients may tolerate a full dose of Adriamycin, we found no evidence that this was associated with a better response rate, which was disappointingly low at only 18%.

The Childrens Cancer Study Group (CCSG) undertook a study (CCG-823F) to test the feasibility of administering continuous infusion doxorubicin (CI DOX) and cisplatin (CDDP) in patients with unresectable or incompletely resected hepatoblastoma (HB) or hepatocellular carcinoma (HCC). Chemotherapy consisted of CI DOX 20 mg/m2/d for days 1 to 4 and CDDP 100 mg/m2 on day 1 followed by a 21-day rest period. Second-look surgery was performed after the administration of four chemotherapy courses. Forty-seven (47) assessable patients were entered on study, 33 with HB and 14 with HCC; of these, 34 (26 HB and eight HCC) completed the initial four courses of chemotherapy. Of the 26 HB patients, 25 were evaluated as responding to chemotherapy before the scheduled second-look procedure and were considered surgically resectable at that time. Surgery was performed on 22 patients; three patients refused the second-look surgery. Nine patients had no evidence of residual malignant disease, seven underwent surgical resection of remaining tumor, four were left with microscopic residual disease, one had a partial resection with gross tumor left behind, and one remained unresectable. Nine HCC patients completed four chemotherapy courses. Eight patients achieved a partial remission and second-look surgery was attempted on seven. Only two had all malignant disease removed at the second procedure. Data from 225 courses of chemotherapy were evaluated for toxicity. Neutropenia (absolute granulocyte count less than 500/mL) was observed in 68 courses, and five of these episodes were associated with sepsis. Severe mucositis was documented in 21 courses, and hypomagnesemia (magnesium less than 1.2 mg) was noted in 30 patients. Two patients developed decreased left ventricular shortening fraction, which resolved when chemotherapy was discontinued. In summary, CI DOX plus CDDP is a well-tolerated and effective regimen in inducing surgical resectability in HB patients who are unresectable at diagnosis and significantly improves survival for this group of patients to 66.6%.

A 63-year-old Japanese woman who was being treated for liver cirrhosis was diagnosed as having hepatocellular carcinoma in the caudate lobe of the liver. Transcatheter hepatic arterial chemoembolization was performed for this lesion, but severe neutropenia occurred. To restore white blood cell (WBC) counts, recombinant human granulocyte colony-stimulating factor (rhG-CSF) was administered (250 micrograms per day during 10 days, intravenously). Subsequently, WBC counts recovered immediately without side effects. This suggests that rhG-CSF could be useful for the treatment of neutropenia after chemoembolization, even in cirrhotic patients.

The toxic effects and tissue uptake of both cisplatin and oxaliplatin--[(1R, 2R)-1,2-cyclohexanediamine-N,N'] [oxalato(2-)-O,O']platinum--were previously shown to vary similarly according to dosing time in mice. A 4-hour infusion of cisplatin resulted in fewer side effects and allowed administration of higher doses at 16 hours than at 4 hours in patients with cancer. We hypothesized that the continuous venous infusion of oxaliplatin for 5 days would be less toxic and would deliver a higher dose to the patient if the drug were infused at a circadian rhythm-modulated rate (peak at 16 hr; schedule B) rather than at a constant rate (schedule A). We tested this hypothesis in a randomized phase I trial. We escalated the dose of oxaliplatin to the patient by 25 mg/m2 per course. Courses were repeated every 3 weeks. An external, multichannel, programmable-in-time pump was used for the infusions. Toxicity was assessable for 94 courses in 23 patients (12 patients with breast carcinoma, nine with hepatocellular carcinoma, and two with cholangiocarcinoma). The incidence of neutropenia of World Health Organization grades II-IV and the incidence of distal paresthesias were 10 or more times higher (P less than .05) with schedule A than with schedule B. In addition, vomiting was 55% higher (P = .15) with schedule A than with schedule B. Furthermore, with schedule B, the mean dose of oxaliplatin (P less than .001) and its maximum tolerated dose (P = .06) could be increased by 15% over those doses with schedule A. An objective response was achieved in two of the 12 patients with previously treated breast cancer. We recommend that the dose of oxaliplatin for phase II trials be 175 mg/m2, delivered according to the circadian rhythm-modulated rate.

In a prospective trial of 75 Chinese patients with histologically proven inoperable hepatocellular carcinoma (HCC), 25 patients were randomised to receive doxorubicin 60-75 mg m-2 intravenously once every 3 weeks, 25 to receive recombinant alpha 2 interferon (rIFN) (Roferon) 9-18 x 10(6) IU m-2 intramuscularly (i.m.) daily and 25 to receive rIFN 25-50 x 10(6) IU m-2 i.m. three times weekly. Patients were switched to the other drug if: (a) there was progressive disease after 12 weeks, (b) unacceptable toxicity developed and (c) they had received a total of 500 mg m-2 of doxorubicin. Six patients had switching over of therapy, three on doxorubicin and three on rIFN. In the remaining 69 patients on single drug therapy, the median survival rate of patients on doxorubicin and rIFN was 4.8 and 8.3 weeks respectively (P = ns.). rIFN induced tumour regression of 25-50% in 12% of patients and of over 50% in 10% of patients. When compared with doxorubicin, rIFN was associated with more tumour regression (P = 0.00199) and less progressive tumours (P = 0.00017). It caused less prolonged and less severe marrow suppression (P = 0.01217), and had significantly less fatal complications than doxorubicin (P = 0.01383). Doxorubicin caused fatal complications due to cardiotoxicity and neutropenia in 25% of patients. rIFN was associated with fatal complications due to dementia and renal failure in 3.8% of patients. In the treatment of inoperable HCC, rIFN is superior to doxorubicin in causing more tumour regression, less serious marrow suppression and less fatal complications.

To assess the efficacy and safety of Adriamycin (Adria Laboratories, Columbus, OH) in inoperable hepatocellular carcinoma (HCC), 60 patients were randomized to receive Adriamycin 60 to 75 mg/m2 at 3-week intervals and 46 patients to receive no antitumor therapy. The median survival rate of the Adriamycin group was 10.6 weeks; that of the group receiving no antitumor therapy was 7.5 weeks (P = 0.036). Adriamycin induced tumor regression of 25% to 50% in 5% of patients and of over 50% in only 3.3% of patients. It caused fatal complications (septicemia and cardiotoxicity) in 25% of patients. The severity of neutropenia leading to septicemia for a particular dose was unpredictable. Four of eight patients who developed cardiotoxicity received less than 500 mg/m2 of Adriamycin. We conclude that Adriamycin is not an ideal drug for the treatment of inoperable HCC.

Twenty-three patients (16 male, seven female) with hepatocellular carcinoma (HCC) were treated by hepatic arterial infusion (HAI) of mitoxantrone every 4 weeks. At each treatment, a catheter was inserted percutaneously into the main hepatic artery via the femoral artery under image intensification. Treatment consisted of a 24-hour continuous HAI of mitoxantrone, 6 mg/m2/d X 3 (eight patients) or 10 mg/m2/d X 3 (14 patients) without heparin. Eight patients had only one infusion, nine patients four infusions, five patients three infusions, two patients two infusions, and one patient five infusions. A partial response was seen in six patients, with a median duration of 20 weeks (range, 18 to 38 weeks). Five patients achieved stable disease, with a median duration of 20 weeks (range, 11 to 42 weeks). The median survival of the overall group was 22 weeks. Survivals of responding, stable, and nonresponding patients were 32 weeks, 24 weeks, and 9 weeks, respectively. Complications of catheter placement included asymptomatic dissection of the hepatic artery (one patient), and asymptomatic thrombosis of the hepatic artery (five patients). Three patients experienced mild nausea and vomiting, and six patients had mild to moderate alopecia. Granulocytopenia was frequent at both dose schedules. The granulocyte nadir was greater than 1,000/microL in 34% of evaluable courses, 500 to 1,000/microL in 32%, and less than 500/microL in 34% of courses. Two patients developed neutropenia-associated fever. A platelet nadir below 100,000/microL was seen after only 10% of courses, and only two patients had platelets below 50,000/microL. Seven patients received doxorubicin after progression on mitoxantrone. Four received systemic doxorubicin, 50 mg/m2, and three HAI of doxorubicin, 25 mg/m2, for three days. Two patients achieved partial response (18 weeks and 32 weeks) to HAI doxorubicin. Mitoxantrone has activity in HCC and is well tolerated when administered by HAI. It is not entirely cross-resistant with doxorubicin.

The association of large granular lymphocyte leukemia (LGL-L) with hepatocellular carcinoma in a 55-year-old patient is described. An increased number of LGL was seen on peripheral blood smears. The immunophenotype was CD3+, CD4-, CD8+, and a study of the TCR gene rearrangement indicated the monoclonal nature of the proliferation. A liver mass was detected on CT scan and an ultrasound-guided fine needle biopsy revealed the presence of hepatocholangiocellular elements. A right hepatectomy was performed. Major neutropenia persisted despite corticosteroids and granulocyte colony-stimulating growth factor (G-CSF) therapy. Methotrexate at 20 mg/week failed to control lymphocytosis after three months of treatment. A new nodule of hepatocarcinoma reappeared twelve months after surgery and a liver resection was performed.

Hepatocellular carcinoma remains a highly chemoresistant neoplasm. In this study of the topoisomerase I inhibitor topotecan a response rate of 13.9% (95% confidence interval 4.7%-29.5%) was obtained utilizing a five consecutive day bolus infusion schedule. There were no complete responses and the median survival was only eight months. Furthermore, treatment with topotecan produced significant toxicity with two-thirds of patients experiencing life-threatening (grade 4) neutropenia. When used in this dose and schedule, topotecan does not appear to be effective for patients with advanced hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a common lethal disease in Asia and there is no effective chemotherapy. Identification of new effective drugs in the treatment of inoperable HCC is urgently need. This is a phase II clinical study to investigate the efficacy, toxicity and pharmacokinetics of paclitaxel in HCC patients. Twenty patients with measurable, unresectable HCC, normal serum bilirubin, normal bone marrow and renal functions were studied. Paclitaxel 175 mg m(-2) was given intravenously over 3 h every 3 weeks. No complete or partial responses were observed. Five patients had stable disease. Major treatment toxicities (grade 3-4) were neutropenia (25%), thrombocytopenia (15%), infection (10%) and allergy (10%). Treatment-related deaths occurred in two patients. The median survival was 12 weeks (range 1-36). Paclitaxel is metabolized by the liver and the pharmacokinetics of paclitaxel in cancer patients with liver involvement or impairment may be important clinically. Pharmacokinetic study was completed in 13 HCC patients. The paclitaxel area under the curve was significantly increased (P < 0.02), clearance decreased (P < 0.02) and treatment-related deaths increased (P = 0.03) in patients with hepatic impairment. In conclusion, paclitaxel in this dose and schedule has no significant anti-cancer effect in HCC patients. Paclitaxel should be used with caution in cancer patients with liver impairment.
