Intracavitary therapy of neoplastic effusions with cytokines: comparison among interferon alpha, beta and interleukin-2.

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; 6 x 10(6) IU), interferon (IFN alpha; 2 x 10(7) U) or IFN beta (6 x 10(6) 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 IFN alpha or -beta, 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, IFN alpha and -beta, 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.

A randomized study of neuroimmunotherapy with low-dose subcutaneous interleukin-2 plus melatonin compared to supportive care alone in patients with untreatable metastatic solid tumour.

Recent advances in our knowledge of psychoneuroimmune interactions involved in the control of tumour growth have shown the possibility of manipulating host anticancer defenses through a neuroimmunotherapeutic strategy. In particular, our previous studies have demonstrated that the concomitant administration of the pineal neurohormone melatonin may amplify the antitumour efficacy of interleukin-2 (IL-2) in humans. On this basis, a study was planned to investigate the influence of neuroimmunotherapy with low-dose IL-2 plus melatonin on survival time and on performance status in untreatable metastatic cancer patients. The study included 100 patients with metastatic solid tumours, for whom no standard therapy was available. They were randomized to receive IL-2 (3 x 10(6) IU/day subcutaneously for 4 weeks) plus melatonin (40 mg/day orally) or supportive care alone. Partial tumour regressions were seen in 9/52 (17%) patients treated with the immunotherapy, and in none of the patients treated with supportive care alone. The percentage of survival at 1 year was significantly higher in patients treated with IL-2 and melatonin than in those receiving the supportive care alone (21/52 versus 5/48, P < 0.005). Moreover, the performance status improved in 22/52 patients of the immunotherapy group and in only 8/48 patients treated with supportive care (P < 0.01). This study shows that cancer neuroimmunotherapy with low-dose IL-2 and the pineal hormone melatonin may prolong survival time and improve the quality of life of patients with metastatic solid tumours who do not respond to conventional therapies.

Vinorelbine as single agent in pretreated patients with advanced breast cancer.

Vinorelbine is a new semisynthetic vinca alkaloid with high activity against breast cancer. In this multicenter clinical study we evaluated the activity and toxicity of vinorelbine as a single agent in 30 advanced breast cancer patients pretreated with anthracycline and/or mitoxantrone (24 with recurrent tumor, 6 with non operable cancers). Vinorelbine was given at a weekly dose of 20 mg/m2 for a minimum of 3 weeks. Treatment was continued until there was disease progression or evidence of serious toxicity. Predominant sites of metastasis were viscera (14 cases), soft tissue (11 cases) and bone (5 cases). A median number of 12 doses of vinorelbine (range 3-34) were administered to each patient. Objective responses were recorded in 11 of them and 15 had minimal responses or stable disease. Four patients showed progression of disease during vinorelbine chemotherapy. The median duration of response was 5 months (2-14). The median survival time was 7 months (2-20+): 9 months for responders and 5 months for those with stable or progressive disease. The most important and dose-limiting toxicity was represented by leukopenia. The compliance of patients was very good and the treatment was well accepted by them all including those with low performance status. In conclusion, this study provides further evidence that a weekly schedule with vinorelbine as a single agent is effective and well-tolerated also in pretreated advanced breast cancer patients.

A randomized study with the pineal hormone melatonin versus supportive care alone in patients with brain metastases due to solid neoplasms.

BACKGROUND: Unresectable brain metastases remain an untreatable disease. Because of its antitumor cytostatic action and its anticonvulsant effect, the pineal hormone melatonin could constitute a new effective agent in the treatment of brain metastases. The current study was performed to evaluate the effect of melatonin on the survival time in patients with brain metastases due to solid neoplasms. METHODS: The study included 50 patients, who were randomized to be treated with supportive care alone (steroids plus anticonvulsant agents) or with supportive care plus melatonin (20 mg/day at 8:00 p.m. orally). RESULTS: The survival at 1 year, free-from-brain-progression period, and mean survival time were significantly higher in patients treated with melatonin than in those who received the supportive care alone. Conversely, steroid-induced metabolic and infective complications were significantly more frequent in patients treated with supportive care alone than in those concomitantly treated with melatonin. CONCLUSIONS: The pineal hormone melatonin may be able to improve the survival time and the quality of life in patients with brain metastases due to solid tumors.

Low-dose interleukin-2 subcutaneous immunotherapy in association with the pineal hormone melatonin as a first-line therapy in locally advanced or metastatic hepatocellular carcinoma.

Experimental studies have showed that hepatocellular carcinoma (HCC) cells are susceptible to cytolysis of interleukin (IL)-2-activated lymphocytes. Moreover, our previous studies demonstrated that the pineal neurohormone melatonin (MLT) may enhance IL-2 efficacy. On this basis, a study was started with low-dose IL-2 (3 million U/day subcutaneously for 6 days/week for 4 weeks) plus MLT (50 mg/day orally every day given in the evening) as a first-line therapy of unresectable HCC. The study included 14 patients. Objective tumour regressions were obtained in 5/14 (36%) patients (one complete response, four partial responses), with a median duration of 7+ months. 6 patients had stable disease, while the other 3 progressed. Toxicity was low in all cases. This study shows that the neuroimmunotherapy with low-dose IL-2 plus MLT is a new well-tolerated and effective therapy of advanced HCC.

A randomised study with subcutaneous low-dose interleukin 2 alone vs interleukin 2 plus the pineal neurohormone melatonin in advanced solid neoplasms other than renal cancer and melanoma.

Our previous experimental studies have shown that the best approach to increase the biological anti-tumour activity of interleukin 2 (IL-2) is not co-administration of another cytokine, but the association with immunomodulating neurohormones, in an attempt to reproduce the physiological links between psychoendocrine and immune systems, which play a fundamental role in the regulation of the immune responses. In particular, the association with the pineal neurohormone melatonin (MLT) has been shown to cause tumour regressions in neoplasms that are generally non-responsive to IL-2 alone. To confirm these preliminary results, a clinical trial was performed in locally advanced or metastatic patients with solid tumours other than renal cell cancer and melanoma. The study included 80 consecutive patients, who were randomised to be treated with IL-2 alone subcutaneously (3 million IU day-1 at 8.00 p.m. 6 days a week for 4 weeks) or IL-2 plus MLT (40 mg day-1 orally at 8.00 p.m. every day starting 7 days before IL-2). A complete response was obtained in 3/41 patients treated with IL-2 plus MLT and in none of the patients receiving IL-2 alone. A partial response was achieved in 8/41 patients treated with IL-2 plus MLT and in only 1/39 patients treated with IL-2 alone. Tumour objective regression rate was significantly higher in patients treated with IL-2 and MLT than in those receiving IL-2 alone (11/41 vs 1/39, P < 0.001). The survival at 1 year was significantly higher in patients treated with IL-2 and MLT than in the IL-2 group (19/41 vs 6/39, P < 0.05). Finally, the mean increase in lymphocyte and eosinophil number was significantly higher in the IL-2 plus MLT group than in patients treated with IL-2 alone; on the contrary, the mean increase in the specific marker of macrophage activation neopterin was significantly higher in patients treated with IL-2 alone. The treatment was well tolerated in both groups of patients. This study shows that the concomitant administration of the pineal hormone MLT may increase the efficacy of low-dose IL-2 subcutaneous therapy.

A randomized study of low-dose interleukin-2 subcutaneous immunotherapy versus interleukin-2 plus interferon-alpha as first line therapy for metastatic renal cell carcinoma.

AIMS AND BACKGROUND: IL-2 given subcutaneously in combination with interferon-alpha 2b (IFN) appears to induce a response rate comparable to that obtained with IL-2 intravenous injection in patients with metastatic renal cell carcinoma (RCC) but with lower toxicity. The role of IFN when combined with IL-2 has however still to be defined. The present study was performed to draw some preliminary conclusions about the effect of IFN in combination with IL-2 in metastatic RCC. METHODS: The study included 30 consecutive patients with metastatic RCC who were randomized to treatment with IL-2 subcutaneous therapy (3 million IU twice/daily for 5 days/week for 6 weeks) or with IL-2 plus IFN (5 million U/m2 subcutaneously thrice weekly). In patients without progressive disease, a second cycle was repeated after a 28-day rest period. RESULTS: No significant difference in partial response rate was found between patients treated with IL-2 alone and those given IL-2 plus IFN (5/15 vs 4/15). Similarly, no difference was seen in the percentage of stable disease (7/15 vs 7/15). Toxicity was higher in patients who received IL-2 plus IFN. Lymphocyte and eosinophil mean increase was higher in patients treated with IL-2 alone than in those treated with IL-2 plus IFN, without however any significant difference. CONCLUSIONS: The present results, which require confirmation in a larger series, indicate that combination with IFN does not increase the efficacy of IL-2 subcutaneous immunotherapy in metastatic RCC but only the toxicity of treatment.

Subcutaneous therapy with low-dose interleukin-2 plus the neurohormone melatonin in metastatic gastric cancer patients with low performance status.

AIMS AND BACKGROUND: Patients with disseminated gastric cancer are generally in very bad clinical conditions, which make them not eligible for potentially active polychemotherapies. This justifies the development of less toxic therapies such as the use of biological response modifiers. Unfortunately, IL-2, one of the most promising cytokines, does not seem to be effective in gastric cancer. Our previous studies have shown that the pineal hormone melatonin (MLT) may amplify IL-2 activity, which becomes biologically effective also at very low doses. Based on these considerations, a pilot study was performed with low-dose subcutaneous IL-2 in combination with MLT in metastatic gastric cancer patients with low performance status. METHODS: The study included 14 patients with metastatic gastric cancer who received IL-2 at a dose of 3 million IU/day at 8.00 p.m. subcutaneously for 6 days/week for 4 weeks. MLT was given orally at a dose of 50 mg/day at 8.00 p.m. every day starting 7 days before IL-2. In patients in whom the disease did not progress, a second cycle was given after a rest period of 21 days. RESULTS: A tumor regression was obtained in 3/14 (21%) patients, complete response in 1 and partial in 2, with a median duration of 13 + months. The disease stabilized in 6/14 (43%) patients and progressed in the remaining 5 (36%). Survival was significantly longer in patients with response or stable disease than in those with progression. Toxicity was low in all cases. CONCLUSIONS: These preliminary results show that the combination on of low-dose subcutaneous IL-2 and the pineal hormone MLT may represent a new well tolerated biotherapy, capable of inducing objective tumor regression also in patients with metastatic gastric cancer and low performance status.

Respiratory distress syndrome in patients with advanced cancer treated with pentoxifylline: a randomized study.

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.

Effects of a preoperative course of interleukin-2 on surgical and immunobiological variables in patients with colorectal cancer: a phase 2 study.

OBJECTIVE: A phase 2 study to evaluate the effects of a short preoperative course of interleukin-2 (IL-2) on the postoperative course of patients with cancer. DESIGN: Open study. SETTING: San Gerardo Hospital, Monza, Italy. SUBJECTS: 16 Consecutive patients with locally advanced colorectal cancer, with or without metastases. INTERVENTION: IL-2 in a dose of 9 x 10(6) IU/m2 twice daily for three days; patients were operated on within 36 hours of the cessation of IL-2 treatment. MAIN OUTCOME MEASURES: Morbidity, mortality, and changes in numbers of lymphocytes, T lymphocytes, natural killer (NK) cells, and CD25 (cluster of determination) positive cells. RESULTS: There was no morbidity or mortality--in particular, there were no infections even in the patients who were at highest risk. The mean numbers of lymphocytes, T lymphocytes, NK cells, and CD25 positive cells increased significantly during the postoperative period. All patients showed evidence of infiltration of lymphocytes or eosinophils (or both) into the tumour tissue. CONCLUSIONS: The results suggest that a three day course of IL-2 preoperatively is well tolerated, stimulates would repair, neutralizes the lymphocytopenia induced by major operation, and induces immune cells to infiltrate the tumour. Randomised studies are needed to confirm these results.

[Immunotherapy with low-dose subcutaneous interleukin-2 in metastatic renal carcinoma].

The intravenous injection of interleukin-2 (IL-2) has appeared to induce tumor regression in metastatic renal cell carcinoma (RCC). IL-2 given subcutaneously has also appeared to be effective when it is administered in association with interferon-alpha (INF), but with a lower toxicity in comparison to the intravenous route of administration. The present study was carried out to evaluate the efficacy of a subcutaneous immunotherapy with IL-2 alone in metastatic RCC. The study included 30 consecutive patients affected by metastatic RCC, 14 of whom had been pretreated with INF plus vinblastine, while the other 16 patients received IL-2 as a first line therapy of their metastatic disease. IL-2 was given subcutaneously at a dose of 3 million IU twice/day for 5 days/week for 6 consecutive weeks, corresponding to one cycle of immunotherapy. No complete response was obtained. A partial response (PR) was achieved in 10/30 (33%) patients (median duration: 7 months, range 5-25), without any significant difference between patients pretreated with IFN and nonpretreated patients (4/14 vs 6/16). Response rate was significantly higher in nephrectomized patients than in those who did not undergo nephrectomy (10/25 vs 0/5; P < 0.01). Moreover, response rate was significantly higher in patients with performance status (PS) greater than 40% than in those with PS lower than 40% (10/23 vs 0/7; P < 0.01). A stable disease (SD) was obtained in 12/30 (40%) patients (median duration 5 months, range 3-13), while the remaining 8/30 (27%) progressed. The increase in lymphocyte and eosinophil mean number was significantly higher in patients with PR or SD than in the progressed ones.(ABSTRACT TRUNCATED AT 250 WORDS)

Neuroimmunotherapy with subcutaneous low-dose interleukin-2 and the pineal hormone melatonin as a second-line treatment in metastatic colorectal carcinoma.

On the basis of our previous preliminary data which showed that the pineal hormone melatonin (MLT) may potentiate IL-2 activity and reduce the dose of IL-2 required to determine an effective host antitumor response, we performed a clinical study with low-dose IL-2 given once/day subcutaneously (3 million IU/day for 6 days/week for 4 weeks) in association with MLT (50 mg/day orally at 8.00 p.m. every day) as a second-line therapy in metastatic colorectal cancer patients pretreated with 5-fluorouracil. Evaluable patients were 13/14, and most of them showed disseminated liver metastases. No objective tumor regression was seen. A stabilization of disease was achieved in 4/13 patients (median duration 5+ months), and the other 9 patients progressed. Mean number of lymphocytes and eosinophils significantly increased during the treatment. Moreover, the mean increase in lymphocyte number was significantly higher in patients with stable disease than in those with progressive disease, whereas there was no difference as regards eosinophils. Serum levels of neopterin and tumor necrosis factor (TNF) significantly increased during therapy, and TNF increase was correlated to the side effects rather than to the control of cancer development. This study shows that neuroimmunotherapy with low-dose interleukin-2 and MLT, even though capable of determining an evident expansion of immune cells involved in host antitumor response, does not seem to be effective in terms of tumor regression in metastatic colon cancer patients pretreated with 5-fluorouracil.

Weekly doxorubicin chemotherapy for breast cancer in pregnancy. A case report.

The simultaneous occurrence of breast cancer and pregnancy is rare. Little data are available about cytostatic treatment in patients with breast cancer during pregnancy. We report on a 31-year-old woman with a 28-week pregnancy and a T3 N+ Mx breast cancer treated with weekly doxorubicin chemotherapy. This was a well tolerated treatment without toxicity or complications for the mother. A partial response of the tumor was observed after 4 treatment courses. A normal baby was delivered. Doxorubicin and its metabolites were not detected in amniotic fluid collected through amniocentesis. Macroscopic and pathologic examinations of the placenta were normal. Although larger experiences are needed, weekly doxorubicin seems to yield satisfactory results without additional risks of fetal distress or malformations when given in women during the second and third trimester of pregnancy.

Intracavitary administration of interleukin-2 as palliative therapy for neoplastic effusions.

Cytokines have recently appeared to be effective in the palliative therapy of neoplastic effusions. The present study was carried out to evaluate the efficacy and the tolerability of an intracavitary injection of IL-2 in patients with neoplastic effusion due to solid tumors. The study included 14 patients with cytologically positive effusion (pleura, 11; peritoneum, 2; pericardium, 1). Tumor histotypes were: mesothelioma, 5; non-small cell lung cancer, 3; breast cancer, 2; ovarian cancer, 2; cervix carcinoma, 1; unknown primary tumor, 1. The efficacy was evaluated according to the criteria of Paladine et al. (Cancer 38: 1903, 1976). An objective response was achieved in 10/14 (71%) patients (4 CR, 6 PR), with a median duration of 4 months (range, 2-8). No important toxicity was seen. This preliminary study showed that low dose IL-2 given intracavitarily is an effective and well-tolerated therapy in patients with neoplastic effusions.

Second line therapy with low-dose subcutaneous interleukin-2 alone in advanced renal cancer patients resistant to interferon-alpha.

Interleukin-2 (IL-2), given subcutaneously with interferon-alpha, induces clinical results similar to those achieved with intravenous administration in advanced renal cancer but with lower toxicity. This study was performed to investigate the efficacy of IL-2 subcutaneous therapy alone in advanced renal cancer patients pretreated with interferon-2 alpha. The study included 13 evaluable patients, 6 of whom had visceral metastasis sites. The cycle consisted of IL-2 at 9 x 10(6) IU/m2 twice daily for 2 days, followed by 1.8 x 10(6) IU/m2 every 12 h for 5 days/week for 6 weeks. Clinical responses were: partial response: 4(31%); stable disease: 7(54%), progressive disease: 2(15%). The median duration of response was 9+ months (range 6(+)-12+). Toxicity was low in all patients, and in particular no important cardiovascular side-effect was seen. The results of this study show that IL-2 subcutaneous therapy alone is an effective and well tolerated treatment in advanced renal cancer patients progressed under interferon-alpha therapy.

Biological and clinical results of a neuroimmunotherapy with interleukin-2 and the pineal hormone melatonin as a first line treatment in advanced non-small cell lung cancer.

The metastatic non-small cell lung cancer (NSCLC) still remains an untreatable disease, and the role played by chemotherapy has yet to be defined. The new immunotherapeutic strategies, such as interferon and IL-2, seem to be also less effective, since they generally determine only a stabilisation of disease. On the basis of previous experimental results suggesting a synergistic action between IL-2 and the pineal neurohormone melatonin (MLT), a study was started to evaluate the clinical efficacy and toxicity of a neuroimmunotherapeutic combination consisting of IL-2 plus MLT as a first line therapy in metastatic NSCLC. The study included 20 patients (adenocarcinoma: 10; epidermoid cell carcinoma: 7; large cell carcinoma: 3). MLT was given orally at a dose of 10 mg day-1 at 8.00 pm every day, starting 7 days before the onset of IL-2 administration. IL-2 was given subcutaneously at a dose of 3 x 10(6) IU m-2 every 12 h for 5 days/week for 4 weeks, corresponding to one cycle of immunotherapy. In responder patients or in those with stable disease, a second cycle was given after a rest-period of 21 days. A partial response was achieved in 4/20 (20%) patients. Ten other patients had a stable disease (50%), whereas the last six patients progressed. Toxicity was low in all cases. This study shows that the neuroimmunotherapeutic therapy with IL-2 and the pineal hormone MLT may represent a new effective and well tolerated treatment in metastatic NSCLC, with results comparable to those obtained with chemotherapy, but with an apparent lower biological toxicity.

Randomized study with the pineal hormone melatonin versus supportive care alone in advanced nonsmall cell lung cancer resistant to a first-line chemotherapy containing cisplatin.

At present, there is no effective medical therapy in metastatic nonsmall cell (NSC) lung cancer patients who progressed under a first-line chemotherapy containing cisplatin. Since recent data have demonstrated the antineoplastic properties and the lack of toxicity of the pineal hormone melatonin (MLT), a randomized study was designed to evaluate the influence of an MLT treatment (10 mg/day orally at 7.00 p.m.) on the survival time at 1 year from the progression under chemotherapy in respect to supportive care alone in a group of metastatic NSC lung cancer patients, who did not respond to a first-line chemotherapy containing cisplatin. The study includes 63 consecutive metastatic NSC lung cancer patients, who were randomized to receive MLT (n = 31) or supportive care alone (n = 32). The percentage of both stabilizations of disease and survival at 1 year was significantly higher in patients treated with MLT than in those treated only with supportive care. No drug-related toxicity was seen in patients treated with MLT, who, on the contrary, showed a significant improvement in performance status. This randomized study shows that the pineal hormone MLT may be successfully administered to prolong the survival time in metastatic NSC lung cancer patients who progressed under a first-line chemotherapy with cisplatin, for whom no other effective therapy is available up to now.

Modulation of macrophage response to interleukin-2 immunotherapy by interleukin-3 in cancer patients.

It has been observed that neopterin, a specific marker of macrophage activation, increases during cancer immunotherapy with IL-2, and this effect is mediated by interferons produced by IL-2-stimulated lymphocytes. Moreover, our previous studies have shown that neopterin rise during IL-2 immunotherapy is associated with an enhanced release of soluble IL-2 receptor (SIL-2R), which may suppress IL-2-dependent immune functions. This finding would suggest that neopterin increase may be related to the generation of suppressive events, which occur during IL-2 immunotherapy. On the basis of the documented modulatory effect of IL-3 on macrophage functions, we have evaluated the influence of IL-3 on neopterin secretion during IL-2 immunotherapy. The study was performed in advanced lung cancer patients. We have investigated 9 immunotherapeutic courses consisting of IL-2 (6M IU/day s.c. for 5 days/week for 3 weeks) plus IL-3 (1 microgram/(kg x day) i.v. for 14 days, starting 7 days before IL-2). The results were compared to those found during 18 courses with IL-2 alone. Mean neopterin levels increased significantly during IL-2 alone, but not in response to IL-3 plus IL-2. SIL-2R rise was significantly higher during IL-2 than during IL-3 plus IL-2. Mean numbers of NK cells and activated lymphocytes increased significantly in both groups of patients, but were significantly lower at the end of the treatment in patients receiving IL-2 alone than in those treated with IL-3 plus IL-2.(ABSTRACT TRUNCATED AT 250 WORDS)
