    Notes: Abstract Preliminary studies have suggested that the intracavitary administration of cytokines may represent a new effective palliative therapy of malignant effusions. To define further the therapeutic role of cytokines in the treatment of neoplastic fluid accumulation, 70 cancer patients with pleural, pericardial or peritoneal cytologically proven neoplastic effusions were randomized to receive intracavitary cycles with interleukin-2 (IL-2; 6x106 IU), interferon (IFNα; 2x107 U) or IFNβ (6x106 U) every week for 2 or 3 weeks. A clinical control of fluid accumulation was obtained in 39/70 (56%) patients. In patients with mesothelioma, the response rate was significantly higher with IL-2 than with IFNα or-β, while there was no difference in patients with tumors other than mesothelioma. Moreover, the duration of the period during which drainage was not required was significantly longer in patients treated with Il-2 than in the other groups. Toxicity was low in all patients. According to preliminary data, this study demonstrates that intracavitary administration of cytokines, including IL-2, IFNα and-β, is a new well-tolerated palliative therapy for malignant effusions, with an efficacy substantially comparable to that described with the most commonly used treatments with tetracyclines or cytostatic agents.

    Notes: Abstract  Experimental data have suggested that the pineal hormone melatonin (MLT) may counteract chemotherapy-induced myelosuppression and immunosuppression. In addition, MLT has been shown to inhibit the production of free radicals, which play a part in mediating the toxicity of chemotherapy. A study was therefore performed in an attempt to evaluate the influence of MLT on chemotherapy toxicity. The study involved 80 patients with metastatic solid tumors who were in poor clinical condition (lung cancer: 35; breast cancer: 31; gastrointestinal tract tumors: 14). Lung cancer patients were treated with cisplatin and etoposide, breast cancer patients with mitoxantrone, and gastrointestinal tract tumor patients with 5-fluorouracil plus folates. Patients were randomised to receive chemotherapy alone or chemotherapy plus MLT (20 mg/day p.o. in the evening). Thrombocytopenia was significantly less frequent in patients concomitantly treated with MLT. Malaise and asthenia were also significantly less frequent in patients receiving MLT. Finally, stomatitis and neuropathy were less frequent in the MLT group, albeit without statistically significant differences. Alopecia and vomiting were not influenced by MLT. This pilot study seems to suggest that the concomitant administration of the pineal hormone MLT during chemotherapy may prevent some chemotherapy-induced side-effects, particularly myelosuppression and neuropathy. Evaluation of the impact of MLT on chemotherapy efficacy will be the aim of future clinical investigations.

    Notes: Abstract The inappropriate endogenous secretion of tumour necrosis factor (TNF) could play a role in the pathogenesis of acute respiratory distress syndrome (ARDS), one of the most frequent causes of death in cancer patients. Because of its capacity to inhibit TNF secretion in vitro, pentoxifylline (PTX) could be extremely useful in ARDS therapy. In this study 30 advanced cancer patients with ARDS were randomized to receive either the conventional care or conventional care plus PTX (100 mg i.v. twice a day for 7 days followed by an oral administration of 400 mg three times a day) to evaluate the efficacy of PTX in reducing TNF serum levels and in improving the symptoms of this syndrome. Serum levels of TNF were measured before and after 7 days of therapy. The percentage of patients alive at 7 days was significantly higher in the PTX-treated group than in the controls (12/15 versus 3/15; P〈0.001). The mean survival time was significantly higher in the PTX-treated group than in the controls. A clinical and/or radiological improvement was obtained in 11/15 patients treated with PTX and in only 2/15 patients in the conventional care group (P〈0.01). TNF mean levels significantly decrease in the PTX-treated group. These data confirm in vivo the capacity of PTX to inhibit TNF secretion in patients with ARDS. Moreover PTX therapy may improve the symptoms related to ARDS without particular toxic effects.
