Biological response modifiers (BRMs) have greatly modified the immunotherapy of tumors. Interleukin-2 (IL-2) has brought about metastasis regression in some cases of malignant tumors, however, when given systemically, it results in high toxicity. More recently, the subcutaneous administration of IL-2 (combined with alpha-interferon, alpha-IFN) seems to be capable of offering the same chances of therapeutic response, but this time with a lower level of toxicity. The Authors report an evaluation of toxicity in 22 patients treated with a combination of IL-2 + alpha-IFN i.m. with or without chemotherapy. The side-effects present in the majority of cases were: fever, diarrhea and asthenia. Approximately 50% of the patients had nausea/vomiting, mucositis, skin rashes, and slight leukopenia. The following side-effects were noted to a much lesser degree, thrombocytopenia, alterations in hepatic and dizziness and cystitis. Only one patient reached 4th degree toxicity, with mucositis, asthenia and skin rash. All the other patients received the treatment without suspensions for toxicity. Biological evaluations will enable us to determine in the future, the cases which can benefit from therapeutic intensification and thus it would seem opportune at this time to use therapy with acceptable toxicity.

Asthenia is a very common symptom of patients with advanced cancer, but its investigation is hindered by a lack of suitable validated measuring instruments. The goal of the present study was to construct and validate a questionnaire for the study of asthenia in cancer patients, as well as to establish correlations with other symptoms and physiological and biochemical parameters. A group of 31 patients with advanced cancer and a control group of 30 healthy volunteers were examined. The proposed questionnaire, based on visual analogue scales, questions with categorical answers and on the hospital anxiety and depression scale was validated by comparing results of the patient and control groups, by the test/retest method and by comparison with the evaluation of an observer. Correlation with various physiological and biochemical parameters was performed. The questionnaire distinguished well among the patients and control groups. VAS of asthenia proved quite stable over a period of 5 days. Correlations of asthenia with lack of appetite, the hospital anxiety and depression scale, weight, heart rate and serum cortisol levels could be established. No significant correlation between asthenia and various serum markers of inflammation and cytokines, including C-reactive protein, tumour necrosis factor, interleukin-1, and interleukin-2 receptors, could be found. The proposed questionnaire for evaluation of asthenia could be validated in a patient sample of limited size and a simplified questionnaire based on visual analogue scales is being developed for further investigations.

The concomitant generation of macrophage-mediated suppressive events, as documented by the increase in neopterin and soluble interleukin-2 (IL-2) receptor (SIL-2R), and the enhanced production of cortisol, would represent the most investigated phenomena responsible for the reduced anticancer efficacy of IL-2 immunotherapy in humans. Based on our preliminary experimental studies suggesting a modulatory role of IL-3 on immune and endocrine effects induced by IL-2, a study was performed to evaluate the influence of IL-3 on biological effects of IL-2 cancer immunotherapy. We have evaluated 12 immunotherapeutic courses with IL-3 plus IL-2, which were performed in 6 patients with metastatic non-small cell lung cancer. The results were compared to those seen in 22 courses with IL-2 alone, carried out in 12 patients with metastatic non-small cell lung cancer. IL-3 was given intravenously at a daily dose of 1 microgram/kg/b.w. at 6 p.m. for 14 consecutive days, starting 7 days before IL-2. IL-2 was given subcutaneously at a dose of 3 million IU twice/daily for 5 days/week for 3 weeks. The increase in serum levels of the specific macrophage marker neopterin, induced by IL-2, was completely blocked by IL-3. The IL-2-induced SIL-2R rise was significantly lower during IL-3 plus IL-2 than under IL-2 alone. The increase in cortisol levels in response to IL-2 was neutralised by IL-3. The increase in lymphocyte, T lymphocyte, natural killer (NK) cell, activated T lymphocyte and eosinophil mean number was significantly higher during IL-3 plus IL-2 than during IL-2 alone. Episodes of fever, asthenia, anorexia, vomiting, anaemia and thrombocytopenia were significantly more frequent in patients receiving IL-2 alone than in those treated with IL-3 and IL-2. This preliminary study would suggest that IL-3 may improve the tolerability of IL-2 immunotherapy and enhance the biological antitumour properties of IL-2 by neutralising cortisol increase and macrophage-mediated suppressive events, with a following potential amplification of Il-2 anticancer efficacy.

Interleukin-2 (IL-2) therapy is associated with serious toxic effects on the cardiopulmonary system. Less frequent toxicity is described in liver and the gastrointestinal system. A case of severe liver toxicity is described in a patient who underwent long-term immunotherapy with IL-2 (4.5 MU/m(2) s.c. daily, 5 days per week for 6 weeks, with 4 weeks of interval) plus interferon-alpha (IFN-alpha) (3 MU s.c. t.i.w., also covering the intervals between IL-2 cycles) for a metastatic renal carcinoma. A review of the literature is provided. The patient tolerated well the immunotherapy scheduled with apparently only a World Health Organization (WHO) G3 anemia and a G2 asthenia and is still alive, with a disease-free survival of 28 months. Notwithstanding a complete absence of liver function test abnormality during all scheduled clinical controls, the patient developed portal hypertension due to liver cirrhosis, which was histologically demonstrated. All common etiologic viral and toxic agents were ruled out. Long-term IL-2 therapy can induce liver cirrhosis. The appearance of liver and spleen enlargement during IL-2 therapy can be considered an indicator of liver damage. Thus, in this setting, closer monitoring is warranted despite normal liver function tests.
