Abstract
Aims and Background The theraputic role of chemotherapy in advanced non-small cell lung cancer (NSCLC) is controversial because of its potentially detrimental action on host anticancer defenses. On the contrary, IL-2 would seem to prolong survival time by improving the immune status, even though it is generally less effective in determining tumor regression in NSCLC. Our previous studies have suggested the possibility of increasing tumor sensitivity to IL-2 by concomitant administration of immunomodulating neurohormones, such as the pineal hormone melatonin (MLT). On this basis, a study was carried out to evaluate the efficacy of immunotherapy with low-dose IL-2 plus MLT versus chemotherapy in advanced NSCLC. Methods The study included 60 patients with locally advanced or metastatic NSCLC, who were randomized to receive immunotherapy or chemotherapy. The immunotherapy consisted of IL-2 (3 million IU/day subcutaneously for 6 days/week for 4 weeks) and MLT (40 mg/day orally every day, starting 7 days before IL-2); in nonprogressing patients, a second cycle was repeated after a 21-day rest period, then they underwent a maintenance period consisting of one week of therapy every month until progression. Chemotherapy consisted of cisplatin (20 mg/m2) and etoposide (100 mg/m2)/day intravenously for 3 days; cycles of chemotherapy were repeated every 21 days until progression. Results No complete response was obtained. A partial response was achieved in 7/29 patients treated with chemotherapy and in 6/31 patients receiving chemotherapy. The difference was not significant. In contrast, the mean progression-free period and the percentage survival at 1 year was significantly higher in patients treated with immunotherapy than in those treated with chemotherapy. Toxicity was substantially lower in patients receiving immunotherapy than in those given chemotherapy. Conclusions This randomized study showed that immunotherapy with low-dose IL-2 plus MLT is a better tolerated and more effective therapy in terms of survival time than chemotherapy containing cisplatin in patients affected by advanced NSCLC.

Abstract
In order to investigate the production of interleukin-2 (IL-2) in human neoplasms, we determined IL-2 and soluble IL-2 receptors (sIL-2R) in serum from 18 patients with lymphoma and 28 patients with solid tumors, with (15 cases) or without (13 cases) metastases. As controls, 58 healthy subjects were evaluated. Low levels of IL-2 were not observed in patients with lymphoma or limited solid tumor but abnormally low concentrations of IL-2 were seen in 4/15 metastatic solid tumors, associated with abnormally high values of sIL-2R. This preliminary study confirms in vivo the reduced IL-2 production in metastatic solid neoplasms, previously documented in vitro

Abstract
Aims and Background Malignant gliomas remain untreatable as the different therapeutic combinations are generally only palliative. Recent experimental evidence suggests that endogenous opioid peptides are involved in brain tumor growth. The aim of the present study was to evaluate the effect on survival of concomitant administration of the long-acting opioid antagonist naltrexone (NTX) in patients with malignant astrocytomas treated with radiotherapy (RT). Methods 21 patients with high grade malignant gliomas were randomized to receive RT alone or RT plus NTX. The dose of RT was 60 Gy. NTX was given orally at a dose of 100 mg every other day without interruption until disease progression. Results The objective tumor regression rate in patients treated with RT plus NTX was higher than that of those treated with RT alone but not significantly so. On the contrary, the percentage of survivals at 1 year was significantly higher in patients treated with RT plus NTX than in those treated with RT alone (5/10 vs 1/11, P < 0.05). NTX therapy was substantially well tolerated in most patients. Conclusions The finding of longer survival in brain tumor patients treated with RT plus NTX than in those who received RT alone suggests in vivo involvement of endogenous opioid peptides in regulating the growth of malignant astrocytomas.

Abstract
In this study, the authors have analyzed the possible effects of one-year adjuvant treatment with tamoxifen on bone mineral density in postmenopausal breast cancer women. Bone mineral content was studied by photon absorptiometry (I-125), whereas bone balance was analyzed indirectly by serum PTH, osteocalcin, calcitonin, calcium and alkaline phosphatase levels. Bone mineral content and serum bone-related substances were measured before starting treatment and after one year. Results were analyzed using Student's t test for paired data. No difference was found between the two measurements for bone mineral content, PTH, calcitonin, calcium and alkaline phosphatase levels. Measurements at entry and after one year of treatment showed a statistically significant difference ( P < 0.001) only for osteocalcin. In accordance with other authors, we can conclude that treatment with tamoxifen does not cause an increase in menopausal bone resorption. The finding that osteocalcin levels decreased after one year of therapy with tamoxifen is interesting, but further studies are necessary to clarify the role of such levels in predicting a turnover of bone balance towards osteoblastic activity.

Abstract
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.

Abstract
Aims and background In addition to estrogens, prolactin (PRL) and IGF-I have also appeared to stimulate breast cancer growth. The present study was performed to evaluate IGF-I blood levels in operable breast cancer in relation to PRL values and the main prognostic variables. Methods The study included 40 patients, clinical stage T1-3NO-2MO. Venous blood samples were collected before and 7 days after surgery. PRL and IGF-I were measured by radioimmunoassay. The control group consisted of 50 healthy women. Results Mean serum levels of IGF-I were significantly higher in patients than in controls, without any apparent relation to the main prognostic variables, including estrogen receptor and node status. Surgery-induced hyperprolactinemia occurred in 22/40 patients. IGF-I mean concentrations observed in the postoperative period in patients with surgery-induced hyperprolactinemia were significantly lower than those seen in patients showing no postoperative PRL rise. Conclusions The study showed that operable breast cancer may be associated with abnormally high levels of tumor growth factor IGF-I, and that surgery was followed by an IGF-I decline only in patients who showed surgery-induced hyperprolactinemia. Our previous studies have shown that postoperative hyperprolactinemia is a favorable prognostic factors for operable breast cancer. The present study, by showing that a postoperative PRL rise is associated with a fall in IGF-I, would suggest that surgery-induced hyperprolactinemia may determine a lower tumor relapse rate by determining a diminished secretion of breast tumor growth factor IGF-I.

Abstract
Aims and background It is known that the aromatase inhibitors may act by decreasing estrogen levels. Moreover, it is known that estrogens may stimulate the release of prolactin (PRL), which is a growth factor for breast cancer. This phase II study was performed to evaluate the effects of the novel aromatase inhibitor anastrozole on PRL secretion in metastatic breast cancer and the possible influence of PRL pretreatment levels on the efficacy of therapy. Methods The study involved 14 pretreated metastatic breast cancer patients with a poor clinical status. Anastrozole was given orally once a day at 1 mg/day for at least 2 months. To evaluate PRL secretion, venous blood samples were collected before treatment and at 1-monthly intervals during treatment. Results The clinical response consisted of partial response (PR) in 2, stable disease (SD) in 5 and progressive disease (PD) in the remaining 7 patients. Abnormally high pretreatment levels of PRL were seen in 5/14 (36%) patients. Progressing patients showed significantly higher pretreatment levels of PRL than those who achieved PR or SD. None of the patients with high PRL pretreatment levels showed a decline in PRL levels on treatment with anastrozole. Conclusions This preliminary study suggests that anastrozole has no inhibitory effect on PRL secretion in metastatic breast cancer and that the evidence of abnormally elevated concentrations of PRL prior to therapy is generally associated with a lack of efficacy.

Abstract
Mitoxantrone (DHAD), an anthracenedione with antineoplastic properties similar to doxorubicin, was tested for therapeutic efficacy and for immunomodulating action on lymphocyte subsets in 16 metastatic breast cancer patients, 12 of whom had been previously treated with chemotherapy. DHAD was given intravenously at a dose of 14 mg/m1 every 21 days. To evaluate total T lymphocytes (CD3), T helper (CD4), and T suppressor/cytotoxic cells (CD8) and the CD4/CD8 ratio, venous blood samples were drawn before and after the first DHAD cycle. Moreover, in 8/16 patients, B lymphocytes (CD20), T suppressor cells (CD8/CD57), T cytotoxic cells (CD8/CD57), NK (CD16) and IL-2 receptor-expressing cells (CD25) were also measured at the same time. An objective tumor response was achieved in 5/16 (31 %) patients and the response rate was significantly higher in patients pretreated with hormone therapy alone than in those pretreated with chemotherapy. No relation was found between clinical response and changes in the CD4/CD8 ratio. Neither the mean number nor the percentage of CD3, CDA and CD8 cells observed after DHAD were significantly different with respect to those seen before. In contrast, the mean number of T suppressor cells, B lymphocytes and CD25-positive cells was significantly lower after than before DHAD administration, whereas no difference was seen in NK cells. These results confirm in humans the immunomodulating properties of DHAD previously described in experimental conditions. However, the DHAD-induced changes in lymphocyte subsets do not seem to be related to the clinical response in breast cancer.

Abstract
Alterations in size of the pineal body and melatonin secretion have been observed in cancer patients. The present study was carried out to evaluate pineal dimensions in a group of cancer patients and their relation to melatonin blood levels. The study included 70 oncologic patients. As controls, 41 patients with acute or chronic disease other than cancer entered the study. Melatonin serum levels were measured by radioimmunoassay on venous blood samples collected at 9:00 a.m. Pineal size was determined by brain CT scan, by considering the product of the two longest perpendicular diameters, multiplied by the thickness of the stratum. The volume of the pineal body was found to be enlarged in 12/70 (17%) cancer patients, and its mean value was significantly higher than that observed in controls. Melatonin levels were also significantly higher in oncologic patients than In controls. However, there was no correlation between melatonin levels and pineal size in cancer patients. Finally, cancer patients did not show a higher degree of pineal calcifications than controls. The clinical significance of pineal enlargement in cancer patients remains to be understood.

Abstract
Aims Epirubicin is an analogue of doxorubicin with a similar activity but less toxicity. The aim of this study was to evaluate the efficacy and the tolerability of a weekly schedule of epirubicin. Methods Fifty-three patients with metastatic breast cancer, pretreated and/or with a low performance status, were treated with 25 mg/m2/week of the drug. Results Of the 49 evaluable patients, 3 achieved a complete response (6.1 %) and 21 a partial response (42.8 %) with a median duration of 6.3 months. Median survival was significantly higher in responders than in nonresponders: 15.2 vs 6.0 months (P < 0.005). Furthermore, a marked improvement in performance status was observed (ECOG scale). No cardiologic toxicity was observed, and gastrointestinal toxicity was low. Conclusions Epirubicin administered weekly represent a valid alternative to conventional treatments.

Abstract
Aims and background In addition to well-documented endocrine properties of interleukins, hemopoietic growth factors could also exert hormonal activities. In fact, our previous studies have shown that GM-CSF may stimulate cortisol and GH release. In contrast, few data only are available about the possible effects of G-CSF. This study was carried out to investigate endocrine effects of G-CSF in cancer patients. Methods The study included 8 cancer patients who were investigated after G-CSF (0.3 mg subcutaneously) or during saline infusion alone as control by collecting venous samples at zero time and after 2, 4, 6 and 8 h. Serum levels of cortisol, GH, PRL, FSH. LH, TSH and melatonin were measured by the RIA method. Results The circadian rhythm of cortisol was not influenced by G-CSF. No significant differences in mean levels of GH, PRL, FSH or LH were seen after G-CSF and during saline infusion. Both TSH and melatonin decreased after G-CSF, without, however, significant differences with respect to the values seen on saline alone. Conclusions The study showed that G-CSF has no substantial endocrine affects in humans. Therefore, G-CSF would differ from GM-CSF not only for its hemopoietic properties, but also from an endocrine point of view.

Abstract
Aims and background IGF-1 has been proven to be one of the most important growth factors for normal and neoplastic cells. Abnormally high levels of IGF-1 have been observed in cancer patients. Since it has been demonstrated that some growth factors may counteract the action of antitumor cytokines, the presence of increased IGF-1 concentrations could reduce the efficacy of cancer biotherapies with cytokines, such as IL-2. The present study was performed to evaluate the efficacy of IL-2 immunotherapy in relation to the pretreatment levels of IGF-1 in advanced cancer patients. Methods The study included 20 consecutive patients with metastatic renal cell cancer who were treated subcutaneously with IL-2 at 6 million IU/day for 5 days/week for 6 weeks. IGF-1 serum levels were measured by RIA on venous blood samples collected before the immunotherapy, after 3 weeks, and at the end of IL-2 injection. Results Objective tumor regressions were obtained in 5/20 patients, consisting of 1 complete response (CR) and 4 partial responses (PR). Nine patients had stable disease and the last 6 patients progressed. Abnormally high pretreatment levels of IGF-1 were seen in 13/20 patients. The percent of clinical responses (CR + PR) was significantly higher in patients with normal pretreatment concentrations of IGF-1 than in those with elevated levels (4/7 vs 1/13, P < 0.01). No significant changes in mean IGF-1 levels occurred during IL-2 therapy. However, mean IGF-1 levels increased in progressing patients and decreased in those with a response or stable disease, even though none of the differences was statistically significant. Conclusions The study showed that high pretreatment levels of IGF-1 are associated with a reduced efficacy of IL-2 immunotherapy of renal cancer. Further studies are required to establish whether IGF-1 levels simply reflect the extension of disease, or whether they may influence per se the action of IL-2.

Abstract
Aims and Background Beta-interferon (β-IFN) has been proven to influence some IL-2-induced immune effects. On the basis of these experimental data, we evaluated the immunobiologic effects of an association between very low-dose IL-2 and β-IFN in advanced cancer patients. Methods The study was performed in 15 metastatic colon cancer patients, who progressed in response to a first-line chemotherapy with 5-FU plus folates. IL-2 was given subcutaneously at a daily dose of 3 million IU in the evening for 6 days/week for 4 weeks. β-IFN was injected subcutaneously at a dose of 3 million U/day for 7 days before the first IL-2 injection, then thrice/week until the end of IL-2 administration. In nonprogressed patients, a second cycle was given after a 14-day rest period. Results No objective tumor regression was seen. Stable disease was obtained only in 2/15 patients; the other 13 progressed. Toxicity was low in all cases. Natural killer cell and T-activated lymphocyte mean number significantly increased during the immunotherapy. Lymphocyte and eosinophil mean number also increased, without, however, significant differences. IL-2-induced suppressive events, consisting of an increase in T-suppressor cell number, and soluble IL-2 receptor levels were not blocked by β-IFN. Conclusions The study showed that the concomitant administration of β-IFN may determine an improvement in the immune performance in metastatic cancer patients treated with very low-dose IL-2, even though this biologic improvement does not seem to be associated to a control of tumor development. Further studies in patients with less advanced disease are needed to better define the impact of the immune improvement induced by low-dose IL-2 plus β-IFN on the clinical course of the neoplastic disease.

Abstract
Aims and Background It is known that interleukin-2 (IL-2) activated cytotoxic lymphocytes require a cell-cell contact to exert their anticancer action. Therefore, the pronounced fibrosis that generally characterizes the neoplastic mass could counteract the action of cytotoxic lymphocytes. Some preliminary studies have shown that progesterone and its analogs may inhibit fibroblast proliferation. On the basis of such evidence, we have designed a clinical study with or without the progestational agent medroxyprogesterone acetate (MPA) in metastatic renal cancer patients in maintenance therapy with IL-2 following response or stable disease (SD) after two cycles of IL-2 subcutaneous immunotherapy, in an attempt to evaluate the influence of MPA on free-from progression (FPP) period. Methods The study included 30 consecutive patients who were randomized to receive IL-2 alone (3 mllion IU twice/day for 5 days/month subcutaneously) or IL-2 plus low-dose MPA (500 mg orally one day/week) without interruption until disease progression. Results A FPP period longer than 1 year was obtained in 8/14 patients treated with IL-2 plus MPA and in only 3/16 patients treated with IL-2 alone. The difference was statistically significant. On the contrary, no significant difference was seen in the mean number of lymphocytes and eosinophils, which was evaluated monthly. Finally, no hyperglycemic or thromboembolic complications occurred in patients concomitantly treated with MPA. Conclusions This preliminary study would suggest that the concomitant administration of low-dose MPA may prolonge the FFP period in metastatic renal cancer patients under maintenance therapy with IL-2. A longer follow-up will be required to evaluate the influence of MPA on overall survival.

Abstract
Aims and background Preliminary experimental data suggest the involvement of tumor necrosis factor (TNF) in determining endothelial damage related to disseminated intravascular coagulation (DIC). The present study was performed to investigate TNF secretion in DIC occurring in metastatic solid tumor patients and to evaluate the possible therapeutic role of pentoxifylline, which has been proven to have a TNF-lowering activity. Methods The study included 20 metastatic solid tumor patients who showed clinical and laboratory signs of DIC. Pentoxifylline was given orally at a dose of 1200 mg/day for 28 days. Results Abnormally high levels of TNF were found in 13/20 patients, and mean TNF serum levels observed in patients were significantly higher than those seen in a control group of 50 healthy subjects. Fibrinogen plasma concentrations were low in 11 cases. Patients with low fibrinogen values showed significantly higher mean TNF levels than those with normal or elevated concentrations. Pentoxifylline therapy induced a significant decrease in mean TNF concentrations and a significant increase in mean platelet number, which returned to within the normal range in 11/20 patients. An increase in platelets in response to pentoxifylline was more evident in patients with elevated pretreatment TNF values. Conclusions Our results suggest the existence of abnormally high blood levels of TNF in cancer-related DIC, mainly in the presence of low fibrinogen values. Moreover, they indicate that pentoxifylline therapy may determine a decrease in TNF levels in DIC patients, an event associated with an increase in platelet number.

Abstract
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.

Abstract
Intravenous interleukin-2 (IL-2) administration has been shown to influence several hormonal secretions. The present study was carried out to investigate the endocrine effects of subcutaneous therapy with IL-2. Six patients with advanced renal cancer were studied. They were treated subcutaneously with IL-2 according to the schedule proposed by Atzpodien et al. Venous blood samples were collected at O-time and 1, 8 and 12 hours after the first IL-2 pulse of 9 × 106 IU/m2 at 8.00 a.m.; on a separate occasion, samples were collected during a saline infusion only. In each blood sample, serum levels of Cortisol, β-endorphin, GH, PRL, FSH, LH, TSH and the pineal hormone melatonin were measured by RIA. Both Cortisol and β-endorphin significantly increased after IL-2 injection. GH rose but not to a significant extent. PRL, FSH, LH and TSH did not change after IL-2. Finally, melatonin levels markedly decreased after IL-2 injection in the only 2 patients with elevated concentrations of this hormone before the start of immunotherapy. These results suggest that the endocrine effects of subcutaneous IL-2 therapy are similar to those previously described with intravenous administration.

Abstract
Measurements of cell cycle kinetics have been found to correlate with the clinical course of patients with breast cancer. However, the thymidine labeling index and more rapid methods like flow cytometry remain complicated and costly. We assessed cell proliferation of 67 breast carcinomas by an immunoperoxidase procedure using a monoclonal antibody, Ki-67, which reacts with a nuclear antigen in proliferating cells. The percentage of Ki-67 positive cells ranged from 2% to 70 %. Tumors with high mitotic rate, high nuclear grade, high histologic grade, and negative estrogen receptors had statistically higher Ki-67 labeling rates. We found no significant differences between the Ki-67 labeling rate and other clinical (age at diagnosis, menopausal status) or pathologic (necrosis, fibrosis, vascular invasion, lymphatic invasion, cellular reaction, tumor size, lymph node metastases) features assessed. These results parallel previously reported data, and confirm that this immunohistochemical staining of breast carcinoma by Ki-67 monoclonal antibody can be considered a rapid and convenient method for assessing cell cycle kinetics. However, further studies, evaluating the correlation between Ki-67 labeling rate and prognosis are needed to better define the real usefulness of this analysis in clinical practice.

Abstract
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.

Abstract
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.

Abstract
Aims and Background Cardiac toxicity has been observed during IL-2 cancer immunotherapy. Because of its trophic action on the myocardial tissue, the use of L-carnitine has been evaluated during IL-2 therapy in advanced cancer patients with clinically important cardiac diseases. Methods The study included 30 cancer patients, who were randomized to treatment with IL-2 alone or IL-2 plus L-carnitine (1000 mg/day orally). IL-2 was injected subcutaneously at a daily dose of 6 million IU for 5 days/week for 4-6 weeks. Results The percentage of cardiac complications was significantly lower in patients concomitantly treated with L-carnitine than those receiving IL-2 alone (0/15 vs 4/15; P < 0.05), whereas no difference was seen in mean creatine phosphokinase levels on study. Conclusions The results would suggest that L-carnitine may be used successfully to prevent cardiac complications during IL-2 immunotherapy in cancer patients with clinically relevant cardiac disorders. Since cardiac metabolism depends mainly on fatty acid oxidation, the stimulatory role of L-carnitine on fatty acid oxidation could explain at least in part its ability to prevent heart disturbances in response to IL-2 administration.

Abstract
Increased capillary permeability and severe hypotension represent the two major cardiovascular complications of IL-2 immunotherapy. The mechanisms responsible for IL-2 cardiovascular toxicity are still obscure. Since increased vascular permeability and vasodilatation may be also induced by the cardiac hormone atrial natriuretic peptide (ANP), we have evaluated ANP concentrations in relation to mean arterial pressure in one patient with metastatic renal carcinoma, treated with a 24-h intravenous infusion of IL-2 at a dose of 3 × 106 Cetus U/m2/day for 5 days. The results showed that episodes of important hypotension were associated with abnormally high plasma levels of ANP. Owing to its vasodilator activity, exagerated ANP secretion, perhaps due to an inappropriate cardiac endocrine function in response to hemodynamic changes induced by IL-2, may play a role in hypotension, which occurs during IL-2 immunotherapy for cancer.

Abstract
It is known that the pineal gland has some antitumor activity. Melatonin, its most important hormone, has been shown to inhibit tumor growth in vivo and in vitro. Moreover, some investigations have demonstrated an altered melatonin secretion in cancer patients. Despite these interesting data, clinical trials have never been carried out to evaluate the effects of melatonin on human neoplasms. The aim of this study was to draw some preliminary conclusions on melatonin therapy in advanced human neoplasms. Nineteen patients suffering from advanced solid tumors, which did not respond to standard therapies, entered the study. Performance status (PS) was 20 or less in 9 cases, and more than 20 in the other 10. Melatonin was given intramuscularly at a daily dose of 20 mg at 3.00 p.m., followed by a maintenance period with lower doses in patients who had a remission, a stabilization of disease or an improvement in PS. Among patients with a PS higher than 20, a partial response was achieved in one case with cancer of the pancreas; moreover, 5 of 10 had stable disease, but the other 4 cases had a progression; an evident improvement of PS was obtained in 6 of the 10 cases. In contrast, among patients with a very poor PS, 7 of 9 died within the first 2 months of therapy. This preliminary study would suggest that melatonin may be of some value in treating cancer patients in whom standard antitumor therapies have failed, particularly in improving their PS and quality of life.

Abstract
Aims and background Interferon (IFN) ± vinblastine (VNB) has appeared to be effective as first–line therapy of metastatic renal cell cancer. This study was performed to establish the efficacy of IFN plus VNB in metastatic RCC previously treated with interleukin-2 (IL-2). Methods The study included 14 metastatic renal cell cancer patients who did not respond to IL-2 subcutaneous therapy or who relapsed after initial response or stable disease. IFN-alpha 2a was given subcutaneously at 3 million U thrice a week in association with VNB (0.1 mg/kg i.v. every 21 days) until progression or toxicity. Patients were considered as evaluable when they were treated for at least 1 month. Results Evaluable patients were 13/14. No patient had a complete response. Partial response was achieved in 2/13 (15%) patients. Stable disease was seen in 5/13 patients, and the last 6 progressed. Conclusions This study, by showing a tumor response rate comparable to that reported with first-line therapy, suggests that previous IL-2 immunotherapy does not influence negatively the efficacy of IFN + VNB in metastatic renal cell cancer.
