Liver transplantation for the treatment of small hepatocellular carcinomas in patients with cirrhosis.

BACKGROUND: The role of orthotopic liver transplantation in the treatment of patients with cirrhosis and hepatocellular carcinoma is controversial, and determining which patients are likely to have a good outcome after liver transplantation is difficult. METHODS: We studied 48 patients with cirrhosis who had small, unresectable hepatocellular carcinomas and who underwent liver transplantation. In 94 percent of the patients, the cirrhosis was related to infection with hepatitis B virus, hepatitis C virus, or both. The presence of tumor was confirmed by biopsy or serum alpha-fetoprotein assay. The criteria for eligibility for transplantation were the presence of a tumor 5 cm or less in diameter in patients with single hepatocellular carcinomas and no more than three tumor nodules, each 3 cm or less in diameter, in patients with multiple tumors. Thirty-three patients with sufficient hepatic function underwent treatment for the tumor, mainly chemoembolization, before transplantation. After liver transplantation, the patients were followed prospectively for a median of 26 months (range, 9 to 54). No anticancer treatment was given after transplantation. RESULTS: The overall mortality rate was 17 percent. After four years, the actuarial survival rate was 75 percent and the rate of recurrence-free survival was 83 percent. Hepatocellular carcinoma recurred in four patients (8 percent). The overall and recurrence-free survival rates at four years among the 35 patients (73 percent of the total) who met the predetermined criteria for the selection of small hepatocellular carcinomas at pathological review of small hepatocellular carcinomas at pathological review of the explanted liver wer 85 percent and 92 percent, respectively, whereas the rates in the 13 patients (27 percent) whose tumors exceeded these limits were 50 percent and 59 percent, respectively (P=0.01 for overall survival; P=0.002 for recurrence-free survival). In this group of 48 patients with early-stage tumors, tumor-node-metastasis status, the number of tumors, the serum alphafetoprotein concentration, treatment received before transplantation, and 10 other variables were not significantly correlated with survival. CONCLUSIONS: Liver transplantation is an effective treatment for small, unresectable hepatocellular carcinomas in patients with cirrhosis.

Psychosocial adaptation after liver transplantation with particular reference to recipients aware of their cancer.

This study investigated the Psychosocial adjustment in 40 patients who received orthotopic liver transplantation (OLT) for several endstage liver diseases. Twenty patients were grafted because they suffered from liver Cancer as well as cirrhosis. Particular attention was paid to evaluating whether cancer could affect recipients' coping with transplant. Each patient underwent a semi-structured interview to obtain information on their psychosocial life, relationship with the donor, organ acceptance and life expectancy. Interview was performed I year after transplantation. A psychodiagnostic evaluation was also performed using a Minnesota Multiphasic Personality Inventory (MMPI) and a Human Figure Test. Psychosocial adaptation in everyday life following liver transplantation seemed good in most of the patients, whatever the indication for transplantation might be. It can he seen that by replacing the diseased organ a high percentage of oncological patients overcame their fear of cancer.

Risk of HBV reinfection after liver transplantation in HBsAg-positive cirrhosis. Primary hepatocellular carcinoma is not a predictor for HBV recurrence. The European Cooperative Study Group on Liver Cancer and Transplantation.

Two hundred and twenty-eight patients who underwent orthotopic liver transplantation for hepatitis B-related cirrhosis in 11 European Liver Transplant Centers were collected. The male/female ratio was 184/44, with a median age of 41 years (13-66). In 55 patients (24%) hepatocellular carcinoma was associated with liver disease. All cases were stratified for pre-orthotopic liver transplantation viral characteristics: HBV-DNA neg/HBeAg neg: 106 patients (47%), HBV-DNA neg/Delta pos: 80 (35.5%), HBV-DNA pos/HBeAg pos: 28 (12.5%), other 14 (5%). In 49 patients (21.4%) post-orthotopic liver transplantation passive prophylaxis with anti-HBs immunoglobulins was not followed, while in 179 patients the anti-HBs serum titer was kept above 100-200 mU/ml. Overall 5-year actuarial survival of the series was 54%. One hundred and eighty-five patients were evaluable for HBsAg reappearance in the serum at various intervals after orthotopic liver transplantation. Overall 3-year HBV-free survival of these patients was 55%. There was a significant difference in 3-year HBV-free survival between HBV-DNA neg (52%), HBV-DNA pos (13%) and Delta pos (73%) patients (p: 0.03). Sixty-three percent of patients in the prophylaxis group were HBV-free, compared to only 25% of untreated patients (p < 0.001). Three-year HBV-free survival in patients with or without HCC was 44% and 59%, respectively. Cox-multivariate analysis revealed that only post-transplantation prophylaxis (p: 0.003) and pre-transplantation viral activity (p: 0.004) can be considered as independent factors affecting HBV recurrence. Candidates with hepatocellular carcinoma in HBV-cirrhosis should not be excluded from orthotopic liver transplantation, supporting the idea of a higher risk of post-transplantation viral reactivation.

The role of somatostatin analogues in the treatment of gastro-enteropancreatic endocrine tumours.

Neuroendocrine (NE) cells are involved in gastro-enteropancreatic (GEP) neoplasms. Biological markers, such as peptides hypersecreted by biologically active NE tumours, aid in the evaluation of response to treatment. For surgically untreatable NE neoplasms, the therapeutic approach remains undefined. Somatostatin analogues, particularly octreotide, can control the clinical effects of hormone overproduction in NE neoplasms and they have revolutionised individualised treatment, particularly for biologically active tumours. So far, like interferon, octreotide used at standard dosages has failed to control neoplastic growth per se. We gave the somatostatin analogue lanreotide to women with advanced breast cancer and to colorectal carcinoma patients. Results confirmed that inhibition of the production of insulin-like growth factor-1, which plays an important role in neoplastic proliferation, could be obtained using the highest doses. Considering these data, we started a clinical trial of 58 patients affected by NE tumours, treated with two sequential doses (500 and 1,000 micrograms subcutaneously t.i.d.) of octreotide. Long-term disease stabilisation (> 6 months) was achieved in 43% of patients but an objective response in only 3%. Good control of clinical symptoms and markers was obtained in 73 and 77% of cases, respectively. Toxicity was negligible. Somatostatin analogues should be carefully evaluated at high doses for possible anti-proliferative effects. Studies are currently investigating their promising association with interferon.

A phase II trial of dacarbazine, fluorouracil and epirubicin in patients with neuroendocrine tumours. A study by the Italian Trials in Medical Oncology (I.T.M.O.) Group.

BACKGROUND: Previous experiences in the treatment of neuroendocrine tumours have demonstrated some activity of single agents such as adriamycin, fluorouracil (FU), streptozotocin and dacarbazine (DTIC). Opinions concerning the usefulness of polychemotherapy in carcinoid tumours are discordant, whereas better results have been achieved in other endocrine pancreatic neoplasms. Based on this background, we used multidrug chemotherapy with DTIC, FU and epirubicin in the treatment of different neuroendocrine tumours. METHODS: The study involved 38 pts with progressive and measurable disease. The treatment schedule was FU 250 mg/m2 i.v., epirubicin 25 mg/m2 i.v., and DTIC 200 mg/m2 i.v. on days 1, 2 and 3 every 3 weeks. RESULTS: The responses achieved by histologic types were carcinoids 2/20, medullary thyroid carcinoma 1/7, neuroendocrine tumours 1/6; and Merkel cell carcinoma 3/5. The median duration of response was 5 months (range 2-11). Stable disease was observed in 13 cases (34%). Out of the 18 cases in progression, 17 had not responded to previous medical treatment. No symptom control was observed in 4 pts with carcinoid syndrome. Treatment toxicity was moderate and included nausea and vomiting, alopecia, leukopenia and mucositis. CONCLUSIONS: Our results document the moderate efficacy of the regimen in all of the histologic types. The major difference in comparison with previous studies was the lower response rate observed in patients with neuroendocrine tumours.

Combined liver and pancreatic islets transplantation in man using cyclosporin immunosuppression.

We report a 1-year patient and graft survival after combined liver-pancreatic islet transplantation. The patient was affected by a pancreatic neuroendocrine carcinoma with extensive liver metastasis. Native pancreas and total liver removal was undertaken after a good response to chemotherapy, and the patient was still cancer-free 1 year later. Normal liver function and insulin independence was achieved, although islet response to glucose challenge remained delayed. Immunosuppression was maintained with cyclosporin monotherapy.

Chemoembolization of hepatocellular carcinoma in patients who undergo liver transplantation.

PURPOSE: To determine the efficacy of chemoembolization (CHE) for hepatocellular carcinoma (HCC) in patients with a cirrhotic liver. MATERIALS AND METHODS: Twenty-one patients with cirrhosis and 33 HCC nodules received a mean of 2.4 cycles of CHE before orthotopic liver transplantation (OLT). Iodized oil plus doxorubicin (13 patients) or mitoxantrone (eight patients) was injected into the hepatic artery. Twelve (57%) of the patients underwent terminal embolization with gelatin sponge pledgets. After OLT, the percentage of tumor necrosis was assessed in each HCC nodule. RESULTS: Twelve (36%) of 33 HCC nodules responded completely to CHE (necrosis > 90%). Successful treatment was statistically significantly related to nodular diameter greater than 2 cm (P = .03), solitariness (P = .0009), hypervascularity (P = .001), and good retention of iodized oil (P = .05). Seven (33%) of the patients had major complications; no death occurred in association with CHE. All patients survived OLT; in three patients (14%), HCC recurred a median of 21 months after OLT. CONCLUSION: CHE seems to be an effective treatment for HCC in patients with liver cirrhosis who await OLT.

Reappraisal of the role of liver transplantation in the treatment of hepatocellular carcinoma arising in cirrhosis.

Several retrospective analyses have recently shown the advantage of liver transplantation (OLT) for patients with hepatocellular carcinoma (HCC) at early tumor stages. Preliminary results of a prospective series of OLT for unresectable small HCC arising in cirrhosis are reported. Eighteen out of 22 patients (82%) are alive without evidence of HCC recurrence after a median follow-up of 11 months.

Prognostic factors in patients affected by hepatocellular carcinoma treated with systemic chemotherapy: the experience of the National Cancer Institute of Milan.

BACKGROUND: Survival times and overall response rates are generally poor in patients with unresectable hepatocellular carcinoma submitted to systemic chemotherapy. Limited data are reported in the literature concerning the factors influencing survival among this subset of patients but the distribution of these variables may affect the results of clinical trials. PATIENTS AND METHODS: The data on 103 patients undergoing systemic chemotherapy at the Istituto Nazionale Tumori from January 1988 through July 1991 have been analyzed using univariate and Cox multivariate analysis. Forty-eight patients were treated with mitoxantrone alone, 40 with mitoxantrone plus beta-interferon, 11 with fluorouracil plus folinic acid and the remaining four with adriamycin. RESULTS: Median survival time, and 6-month and 12-month survival rates, were 7.1, 55% and 29%, respectively. Lactate dehydrogenase value (P = 0.0009), TNM stage (P = 0.001), vascular invasion (P = 0.001), bilirubin (P = 0.008), Child status (P = 0.01), aspartate amino-transferase (P = 0.02), extent of liver involvement (P = 0.02) and performance status (P = 0.03) were the most significant factors influencing survival in univariate analysis. In the multivariate analysis, aspartate amino-transferase (P = 0.02) and, particularly, TNM stage (p = 0.0009) were confirmed as independent variables correlating with survival. A prognostic index was calculated on the basis of these factors and high- and low-risk groups were identified. Median survival time and 12-month survival were 11.1 months and 43% for the low-risk group, and 4.0 months and 9% for the high-risk group (p = 0.0005). CONCLUSION: The results of this analysis may provide guidance for the design of future therapeutic trials in unresectable hepatocellular carcinoma. In particular, patient stratification should be considered for further clinical trials.
