We report here the long-term toleration of treatment with a highly purified human leukocyte alpha-interferon (Interferon Alfanative) in patients with midgut carcinoid tumours with liver metastases. During an 18-month period, 13 consecutive patients with this diagnosis commenced treatment with a-interferon. Five patients died during the first 2 years of treatment due to tumour progression, and in 2 patients the treatment with a-interferon had to be stopped due to severe adverse effects (mainly joint pain and tiredness). Hence, 6 patients tolerated the treatment for a long-term period (greater than 2 years), and in these patients the treatment has continued for more than 3 years; in 3 of them for more than 4 years. In these 6 patients, adverse effects of mild or moderate degree have been observed in 2 patients: itching and hair loss in one and joint pain and hair loss in another. Except for a significant reduction in the blood number of WBC and thrombocytes (although in no patient did leukocytopenia or thrombocytopenia develop) and the development of hypothyroidism in one patient, no biochemical tests have shown significant changes during the long-term treatment. In these 6 patients, objective tumour regression has been observed in 2 patients, stable disease in 3 patients and progression in 1 patient. We conclude that, of the patients initiated on treatment with a-interferon for midgut carcinoids with liver metastases, only approximately 50% are still on the treatment after 2 years. These patients, on the other hand, may continue for a longer period of time with a low degree of adverse effects.

Sonography revealed multiple echo-poor lesions in the liver of a 51-year-old man with nonspecific symptoms (fatigue, drop in performance, pressure sensation in the upper abdomen), increased blood sedimentation rate (68/110 mm) and evidence of cholestasis (gamma-GT 126 U/l, alkaline phosphatase 444 U/l, leucine-aminopeptidase 64 U/l). Under the diagnosis of liver metastases the primary tumour was looked for. These investigations and a fine-needle biopsy having proved unsuccessful, laparoscopy was performed. The biopsies so obtained showed whitish yellow, tight elastic structures indicating gummas of the liver in tertiary syphilis. Treponema-specific IgM antibodies in serum characterized active syphilis requiring treatment. Administration of antibiotics (penicillin 1 mega U daily i.m.; because of allergy replaced after four days by erythromycin 2 g daily for six weeks) resulted in complete normalization of all biochemical findings and, some time later, regression of the gummas. The patient has now been symptom-free for three years. This case illustrates the need even to-day of including syphilis in the differential diagnosis of unclear space-occupying lesions of the liver.

Malignant carcinoid tumours with the carcinoid syndrome has over the years presented a therapeutic challenge. The patients might not only die from tumour progression but also from symptoms relating to hormone overproduction and the specific cardiac disease, e.g. right heart fibrosis and failure. Surgery has been the treatment of choice in local disease, but when liver metastases have developed other treatment procedures must be considered. Conventional chemotherapy has been of little beneficial value, with response rates of only 10-30%, whereas a new somatostatin analogue, octreotid, is effective in controlling clinical symptoms but not tumour progression. Interferon treatment was introduced in 1982 by our group, and we are now presenting treatment results of 130 patients with histologically verified malignant carcinoid tumours and liver metastases. One hundred and eleven patients were treated with a median dose of 6 mega units (MU) of interferon alpha, five times weekly (dose range 3-9 MU), whereas 29 patients received conventional chemotherapy. Forty-seven out of 111 patients (42%) treated with interferon alpha demonstrated a significant biochemical response and 15% demonstrated more than 50% reduction in tumour size. In another 43 (39%) patients stabilization of the carcinoid disease have been noted, whereas 21 (19%) showed progressive disease. The median duration of response was 34 months. Subjective responses with improvement of diarrhoea, flush and/or bronchoconstriction were noticed in 76 patients (68%). The 19 patients treated with chemotherapy demonstrated only 10% biochemical response, lasting for only 3-5 months. The survival analysis demonstrates a median survival of only 8 months in the group of patients treated with chemotherapy, compared to 80+ months (P less than 0.001) in the groups treated with interferon alpha. Interferon adverse reactions of fatigue, weight loss and anaemia were manageable. Neutralizing interferon antibodies were documented in 5-15% of the patients. Interferon alphas are active in patients with malignant carcinoid tumours. Clinical symptoms are significantly reduced following reduction of circulating hormones. Interferon might also have an impact on survival in this group of patients. The side-effects are moderate and managed by dose adjustments.

Malignant carcinoid tumors with the carcinoid syndrome has over the years presented a therapeutic challenge. Surgery is the treatment of choice in local disease but when liver metastases have developed other treatment procedures must be considered. Conventional chemotherapy has been of little benefit, whereas a new somatostatin analogue octreotide gives a good control of clinical symptoms but not of tumor progression. Interferon treatment was introduced in 1982 by our group and we are now presenting results of medical treatment in 130 patients with histologically verified malignant carcinoid tumors and liver metastases. One hundred and eleven patients were treated with alpha-interferon, whereas 19 patients received conventional chemotherapy. Forty-seven out of 111 patients (42%) treated with alpha-interferon demonstrated a significant biochemical response and 15% also more than 50% reduction of tumor size. In another 43 (39%) patients stabilization of the carcinoid disease was noted whereas 21 (19%) showed progressive disease. The median duration of response was 34 months. Subjective response with improvement of diarrheas, flush and/or bronchoconstriction was noticed in 76 patients (68%). Among the 19 patients treated with conventional chemotherapy only 2 showed biochemical response and it lasted only for 3-5 months. The patients treated with chemotherapy had a median survival of only 8 months compared with 80+ months in the group treated with alpha-interferon. The adverse reactions of alpha-interferon are manageable and consist mainly of fatigue, weight reduction and reduction of blood cell counts. Neutralizing interferon antibodies might occur in patients treated with recombinant alpha-interferons (5-15%).

In a pilot clinical trial, treatment of patients with advanced colorectal carcinoma with the combination of fluorouracil (5FU) and recombinant interferon alfa-2a (IFN) resulted in objective tumor regression in 62% of patients. To confirm these findings in a multiinstitutional setting, a phase II clinical trial was initiated by the Eastern Cooperative Oncology Group (ECOG) in 1989. The treatment regimen was identical to that used in the earlier study: 5FU 750 mg/m2/d for 5 days as a continuous infusion followed by weekly outpatient bolus therapy and IFN 9MU subcutaneously beginning day 1 and administered three times per week. Doses were modified for gastrointestinal, hematologic, and neurologic toxicity and for fatigue, similarly to those used in the previous pilot trial. Thirty-eight patients were registered; 36 are evaluable for response (one lost to follow-up and one with nonmeasurable disease). All patients had metastatic or locally recurrent disease beyond the scope of resection; 31 of 38 had liver metastases, and 20 of 38 had two or more sites of involvement. Eight patients had grade 4 toxicities, including sepsis (nonneutropenic) (one), watery diarrhea (two), and granulocytopenia (six). Grade 3 neurologic toxicities were observed in two (5%) patients and included slurred speech and gait disturbance. Objective response was 42% (95% confidence interval [Cl], 27% to 58%), including one clinical complete responder and 14 partial responders. Among the responding patients, the median time to treatment failure was 8 months. Two patients remain on treatment at 10+ and 16+ months: median survival has not been reached. The results of this multiinstitutional trial suggest that the addition of IFN to 5FU enhances the objective response rates achieved in patients with advanced colorectal carcinoma and that the toxicities of this regimen are acceptable.

Fifteen patients with advanced metastatic adenocarcinomas were treated in a phase-I study with continuous intravenous 24 h infusion of recombinant tumor necrosis factor alpha (TNF-alpha) in order to determine the maximum tolerated dose (MTD) and associated side-effects. Patients received 40-400 micrograms/m2 TNF-alpha once (arm A) or twice (arm B) weekly for a scheduled treatment period of 2 months. The observed systemic side-effects resembled those reported for interferons and included fever, chills, fatigue, headaches, myalgias, thrombocytopenia, prostration, and malaise. Dose-limiting toxicities, resulting in a median MTD of 200 micrograms/m2 for 24 h, were fever, chills, fatigue, myalgias, and thrombocytopenia. Out of 15 patients, 11 showed tumor progression, and 3 sustained in no change for over 2 months of treatment. A minor response was seen in 1 patient with a colorectal carcinoma and liver metastases. To reduce side-effects, patients were treated either with paracetamol or indomethacin. Higher MTDs were observed in patients treated with indomethacin. No detectable plasma TNF-alpha levels or TNF antibodies were measured under therapy (plasma TNF-alpha less than 20 pg/ml). We conclude that TNF-alpha appears to have some antineoplastic activity in patients with adenocarcinomas since 4 patients remained in no change or showed a minor response.

Thirteen patients with ileal carcinoids complicated by liver metastases were treated with human leukocyte interferon (IFN) subcutaneously (s.c.) at doses of 3-6 x 10(6) IU/day 5 days weekly during 12 months. Objective tumour response was obtained in 2 patients, based on reduction in tumour size in one patient and on reduction in tumour markers in the other. Stable disease was noted during the 12-month treatment period in 10 patients. Progressive disease was seen in one patient. This patient exhibited tumour growth, new metastases and increases in tumour markers. Among patients with daily flushing prior to treatment, 50% were free of flush after 12 months of IFN. Adverse effects, including a mild influenza-like syndrome, joint and muscle pains, tiredness and reduction of blood cells were observed but did not necessitate long-term dose reductions. Thus, IFN therapy to midgut carcinoid patients resulted in tumour response or stable disease in 12 out of 13 patients without causing severe side effects.

Both interferon-alpha (IFN-alpha) and alpha-difluoromethylornithine (DFMO) have shown modest activity as single-agent therapy in the treatment of malignant melanoma. Several investigators have demonstrated true synergism in vitro of the combination of DFMO and IFN-alpha against human tumor cells, including melanoma. We have investigated this combination in 17 patients with malignant melanoma in a Phase I trial. Patients were treated with 4 or 6 g/m2/day of oral DFMO in 3 divided doses for 11 days, followed by a 3-day rest period. Concomitant administration of 1.5, 3.0, 6.0 or 9.0 x 10(6) U/m2 IFN-alpha intramuscularly was given. The maximum tolerated dose was 4 g/m2/day of DFMO plus 6 x 10(6) U/m2/day of IFN-alpha. Dose-limiting toxicity occurred in 3 of 3 patients receiving 9 x 10(6) U/m2 IFN-alpha and consisted of leukopenia, fatigue, and weight loss. Other toxicities were mild and included reversible hearing loss, diarrhea, nausea, and vomiting. Three responses were seen, including one partial response (PR) of soft tissue metastases, one PR of lung and liver, and one complete response of liver metastases without clearance of carcinomatous meningitis. A Phase II trial has been initiated based on these encouraging results.

Based upon the in vitro synergistic activity of interferon-beta (IFN-beta) and interferon-gamma (IFN-gamma) observed in melanoma cells, we initiated a Phase II trial using the combination to determine the clinical antitumor efficacy in patients with advanced disease. Fifteen patients with metastatic malignant melanoma were given 2,000 micrograms of recombinant IFN-gamma (rIFN-gamma) (Biogen) intravenously (i.v.) over 10 min, followed by a 10 min i.v. injection of 30 million units of recombinant IFN-beta (rIFN-beta ser) (Triton) 3 x/week. Six patients had skin, soft tissue, nodal, or subcutaneous metastases, 6 had visceral disease only, and 3 had both. Seven patients had received prior treatment, including chemotherapy (6), radiotherapy (3), and/or immunotherapy (3). Side effects included typical IFN constitutional symptoms such as anorexia, fatigue, nausea, and myalgias, but were not dose limiting. The mean drop in the white blood cell count (WBC) following 1 month of therapy, compared to baseline, was 3.3 x 10(3)/mm2 (p = 0.002); the mean increase in SGOT was 24.1 U/l (p less than 0.001). One patient had a dose reduction for Grade III anorexia and fatigue which did not resolve with repeated treatment. One patient with liver metastases had radiographical and clinical stabilization of his disease for 1 year. No responses were seen. The median time to progression was 6 weeks. Two patients' tumors were evaluable in the human tumor colony forming assay (HTCFA) and were markedly sensitive to the antiproliferative effects of IFN combinations. Both patients, however, failed to respond clinically.(ABSTRACT TRUNCATED AT 250 WORDS)

In a phase I trial 34 patients with pancreatic cancer were treated with the murine monoclonal antibody (MAb) BW 494 (BI 51.011) directed against a glycoprotein antigen. The patients received repeated doses of MAb over a time period from 5 to 14 days (highest single dose 100 mg, highest cumulative dose 490 mg). During this treatment serum levels of murine IgG increased to 43.4 micrograms/ml. The serum half life of murine IgG ranged from 2 to 3 days. Repeated injections of MAb BW 494 were normally well-tolerated when given within the first 15 days. Two patients presented with fatigue and a neuritis-like syndrome 2 weeks after the last IgG infusion which had resolved spontaneously by the next day. Severe allergic reactions were observed in 3 patients after repeated injections of the MAb. These 3 patients had high levels of human anti-murine antibodies (HAMA). Four weeks after the first application of MAb BW 494, 17/18 patients presented with HAMA (IgG). It could be demonstrated that the anti-murine response was in part anti-idiotypic. At the moment 16/34 patients are eligible for evaluation of tumor response. There was no complete or partial remission; however, 2 patients responded with minor tumor regression up to 32 weeks documented by reduction of liver metastases and primary tumor in CAT scan. Five additional patients presented with a long period of stable disease after immunotherapy (up to 40 weeks). Nine patients had progressive tumor disease in spite of MAb treatment.
