Abstract
It has been shown that low-dose subcutaneous (SC)IL-2 exerts an efficacy similar to that described for the intravenous high-doses in the immunotherapy of metastatic renal cell cancer (RCC). However, it remains to be established which could be the optimal duration of treatment. The most common schedules with subcutaneous IL-2 are generally consisting of 6 weeks of therapy, with an IL-2 dose of about 6 million IU/day. This study was performed to evaluate the efficacy of IL-2 subcutaneous immunotherapy with a duration of 4 weeks only. The study included 13 evaluable metastatic RCC patients. IL-2 has been injected subcutaneously at 6 million IU/day for 6 days/week for 4 weeks, by repeating a second cycle in nonprogressing patients after a 21-day rest period. Objective tumor regressions were achieved in 3/13 (23%) patients consisting of CR in 1 and PR in the other 2. Stable disease was obtained in other 6 patients. This preliminary study would suggest that a shorter dose-matched S.C.IL-2 immunotherapy may have a similar therapeutic efficacy in metastatic RCC. Therefore, the 4-week IL-2 S.C. immunotherapy, instead of the 6-week schedule could become the standard immunotherapeutic schedule, with following decreased cost and toxicity.

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.

Abstract
Several clinical studies have demonstrated the efficacy of subcutaneous immunotherapy with Il-2 alone in metastatic renal cell carcinoma (RCC). In an attempt to better define the clinical parameters which may predict the efficacy of treatment, the present study shows the results obtained with subcutaneous Il-2 alone in 91 evaluable metastatic RCC patients. IL-2 was injected subcutaneously at 3 million IU twice/day for 5 days/week for 6 weeks, corresponding to one immunotherapeutic cycle. In nonprogressing patients, a second cycle was given after 28-day rest period. A complete response (CR) was achieved in 2/91 patients. Moreover, 19/91 patients had a partial response (PR). Therefore, objective response (OR) rate was 21/91 (23%) patients. Stable disease (SD) was achieved in 41 patients, while the remaining 29 patients had a progressive disease (PD). OR rate was significantly higher in patients with a long disease-free survival than in patients with synchronous metastases, in nephrectomized patients than in the non-nephrectomized ones, and in patients with high than in those with low PS. The survival obtained in patients with CR or PA was significantly longer with respect to that found in patients with SD or PD. The toxicity was substantially low in all patients. This study confirms that the subcutaneous immunotherapy with IL-2 alone is an effective and well tolerated therapy of metastatic RCC.

Abstract
Bisphosphonates are potent inhibitors of bone resorption and are commonly used in the treatment of bone metastases. In addition, they seem to influence cytokine secretion. Since the efficacy of IL-2 cancer immunotherapy, in part, depends on endogenous cytokine secretion, bisphosphonates could be effective in modulating IL-2 activity. High pretreatment levels of IL-6 seem to correlate with resistance to IL-2. On this basis, a pilot study was performed to evaluate the in vivo effects of the bisphosphonate, pamidronate, on blood levels of IL-6. The study included 7 patients with bone metastases due to solid tumours. Pamidronate was injected intravenously at 60 mg over 3 h. Venous blood samples were drawn before, at 1-h intervals during pamidronate infusion, then after 1 and 3 days. Mean serum levels of IL-6 significantly decreased during pamidronate infusion, then after 1 and 3 days, IL-6 mean levels still remained lower than control level, but differences were not significant. This preliminary study shows that pamidronate infusion induces a rapid but transient decline in IL-6 blood concentrations, and suggests a possible use of bisphosphonates to modulate the efficacy of IL-2 cancer immunotherapy.

Abstract
Despite the efficacy of IL-2 in the treatment of metastatic renal cell carcinoma (RCC), the prognosis of patients with synchronous metastases still remains poor. Nephrectomy itself, as well as other surgical operations, may further suppress the antitumor immune response. Previous studies suggested that the preoperative injection of IL-2 may neutralize surgery-induced lymphocytopenia in advanced colon cancer. On this basis, a pilot randomized study was performed in an attempt to evaluate the effects of a preoperative administration of IL-2 on postoperative lymphocyte numbers and on the survival in advanced RVV patients with more than 3 synchronous metastases. The study included 20 consecutive patients, who were randomized to receive nephrectomy alone or nephrectomy plus preoperative subcutaneous immunotherapy with IL-2 (18 million IU/day for 3 days). Then, all patients underwent postoperative immunotherapy with IL-2 (6 million IU/day for 5 days/week for 6 weeks). Surgery-induced lymphocytopenia was completely abolished by IL-2 preoperative injection. The frequency of postoperative complications was significantly higher in controls than in patients preoperatively treated with IL-2. On the contrary, significant differences between control and patients preoperatively treated with IL-2 were observed neither in the clinical response to IL-2 immunotherapy, nor in the percent of 1-year survival. The results of this preliminary pilot study would suggest that IL-2 preoperative immunotherapy may neutralize surgery-induced lymphocytopenia and reduce the postoperative complications in RCC patients with synchronous metastases, without, however, influencing their prognosis in terms of survival time.

Abstract
Polychemotherapy represents the only standard medical therapy of metastatic soft tissue sarcomas (STS), whereas the recent biotherapies with cytokines, such as interleukin-2 (IL-2), seem not to have a relevant therapeutic role. The pineal hormone melatonin (MLT), whose immunomodulating activity is well known, would seem to exert a direct cytostatic action on STS cell proliferation. Moreover, MLT has been proven to amplify IL-2 efficacy. On this basis, a pilot phase II study with low-dose IL-2 plus MLT has been performed in untreatable metastatic STS patients. The study included 13 evaluable metastatic STS patients with poor PS, who progressed on at least one previous polychemotherapeutic line. IL-2 was injected subcutaneously at 3 million IU/day for 6 days/week for 4 weeks and MLT was given orally at 40 mg/day in the evening. A partial response was achieved in one patient with leiomyosarcoma. Eight other patients had a stable disease (SD) whereas the remaining 4 patients progressed. A survival longer than 1 year was achieved in 6/13 patients and the percent of 1-year survival was significantly higher in patients with response or SD than in the progressed ones (6/9 vs 0/4). Mean increases in lymphocyte and eosinophil numbers were significantly higher in patients with response or SD than in the progressed ones. These preliminary results would suggest that immunotherapy with low-dose IL-2 plus MLT may have some impact at least on the survival time of untreatable metastatic STS patients with poor clinical conditions.

Abstract
OBJECTIVE Experimental and preliminary clinical studies have suggested that the pineal hormone melatonin (MLT) may stimulate hormone receptor expression on both normal and cancer cells. Moreover, MLT has appeared to inhibit the growth of some cancer cell lines, including prostate cancer, either by exerting a direct cytostatic action, or by decreasing the endogenous production of some tumor growth factors, such as prolactin (PRL) and insulin-like growth factor-1 (IGF-1). On this basis, a study was carried out to evaluate the clinical efficacy of a neuroendocrine combination consisting of the LHRH analogue triptorelin plus MLT in metastatic prostate cancer progressing on triptorelin alone. MATERIAL AND METHODS The study including 14 consecutive metastatic prostate cancer patients with poor clinical conditions (median age: 70.5 years; median PS: 50%), refractory or resistant to a previous therapy with the LHRH analogue triptorelin alone. Triptorelin was injected i.m. at 3.75 mg every 28 days, and MLT was given orally at 20 mg/day in the evening every day until progression, starting 7 days prior to triptorelin. RESULTS AND CONCLUSIONS A decrease in PSA serum levels greater than 50% was obtained in 8/14 (57%) patients. Moreover, PSA mean concentrations significantly decreased on therapy of triptorelin plus MLT. In addition, a normalization of platelet number was obtained in 3/5 patients with persistent thrombocytopenia prior to study. Mean serum levels of both PRL and IGF-1 significantly decreased on therapy. Finally, a survival longer than 1 year was achieved in 9/14 (64%) patients. This preliminary study would suggest that the concomitant administration of the pineal hormone MLT may overcome the clinical resistance to LHRH analogues and improve the clinical conditions in metastatic prostatic cancer patients.

Abstract
Recent experimental studies suggested that hematopoietic cell proliferation and differentiation are under a neuroendocrine control and that they change in relation to the 24-hour period. Moreover, it has been shown that the pineal hormone melatonin (MLT) plays a role in mediating the influence of the psychoendocrine system and of the lighting conditions on the hematopoiesis. Finally, MLT has appeared to regulate hematopoietic cell growth by influencing apoptosis-related mechanisms. In particular, preliminary studies have shown that the pineal hormone MLT may determine some benefits in blood cell disorders, mainly platelet diseases. On this basis, a pilot phase II study of MLT therapy was performed in patients suffering from persistent thrombocytopenia due to different causes. The study included 14 patients, and thrombocytopenia was due to bone metastatic involvement in 5, hypersplenism in 3, myelodysplastic syndrome in 3, DIC in 1, genetic factors in 1, and Werlhof's disease in the last case. MLT was given orally at 20 mg/day in the evening for 2 months. No MLT-related toxicity occurred. A normalization of platelet number was achieved in 8/14 (57%), and platelet mean number significantly increased on MLT therapy. This preliminary study would suggest that MLT may be effective in the treatment of thrombocytopenia due to different reasons, for which no effective standard therapy is available.

Abstract
Several experimental studies have shown that melatonin has an oncostatic action, either by stimulating host antitumor immune defenses or by directly inhibiting the growth of some cancer histotypes, including melanoma. Our previous clinical studies demonstrated that melatonin may induce stabilization of the disease in untreatable metastatic solid tumor patients, and these results have been confirmed by others, at least in patients with metastatic melanoma. On the contrary, at present there are no data related to the possible efficacy of melatonin as an adjuvant endocrine therapy. This study was performed to investigate the impact of melatonin therapy on the disease-free survival (DFS) in melanoma patients surgically treated for regional node recurrence. The study included 30 node-relapsed melanoma patients, who were randomized to receive no treatment or adjuvant therapy of melatonin (20 mg/day orally in the evening) every day until disease progression. After a median follow up of 31 months, the percent of DFS was significantly higher in melatonin-treated individuals than in controls. The DFS curve was also significantly longer in melatonin group than in controls. No melatonin-related toxicity was observed. This preliminary study suggests that an adjuvant endocrine therapy with melatonin may be effective in preventing disease progression in node-relapsed melanoma patients.

Abstract
Preliminary data would suggest that the pineal hormone, melatonin (MLT), may enhance tamoxifen (TMX) anti-tumour efficacy. Both MLT and TMX have been used as single agents in the palliative treatment of metastatic neoplasms, other than the classical hormone-dependent tumours, without, however, any clear efficacy. On this basis, a phase II study with TMX plus MLT has been performed in untreatable metastatic solid tumour patients. The study included 25 metastatic solid tumour patients other than breast cancer and prostate cancer (six unknown primary tumour; four melanoma; four uterine cervix carcinoma; five pancreatic cancer; three hepatocarcinoma; two ovarian cancer; one non-small-cell lung cancer), for whom no other effective standard therapy was available, because of poor clinical conditions, no response to previous chemotherapies and/or chemotherapy-resistant tumours. Both drugs were given orally every day until disease progression (TMX, 20 mg day-1 at noon; MLT, 20 mg day-1 in the evening). Three patients had a partial response (PR) (12%; 95% confidence limits 2-24%) (one cervix carcinoma; one melanoma; one unknown primary tumour). A stable disease (SD) was achieved in 13 other patients, whereas the remaining nine patients progressed. Performance status (PS) improved in 9/25 patients, whose median score increased from 50% to 70%. Finally, a survival longer than 1 year was observed in 7/25 (28%) patients. This phase II study would suggest that the neuroendocrine combination with TMX plus MLT may have some benefit in untreatable metastatic solid tumour patients, either in controlling cancer cell proliferation or improving the PS.

Abstract
It is known that advanced cancer patients may show abnormally low levels of IL-2. The immunotherapy with IL-2 can induce objective tumor regressions, but at present there are no data about the influence of a chronic exogenous IL-2 administration on endogenous secretion of IL-2. This preliminary study was performed to evaluate whether a prolonged IL-2 injection may be able to correct an eventual IL-2 endogenous deficiency in cancer patients. The study included 10 metastatic renal cancer patients, who underwent an immunotherapeutic cycle consisting of IL-2 at 6 million IU/day subcutaneously for 6 days/week for 4 weeks. Serum levels of IL-2 evaluated on venous blood samples collected before and 21 days after the end of IL-2 injection. Before the onset of treatment, abonormally low levels of IL-2 were seen in 6/10 patients. In patients with response or stable disease, mean levels of IL-2 observed 21 days after IL-2 cycle were significantly higher than those seen before therapy, whereas no difference occurred in those who progressed. This preliminary study would suggest that a prolonged subcutaneous injection of low-dose IL-2 may correct an eventual IL-2 endogenous deficiency in advanced cancer patients.

Abstract
Despite the great importance of IL-2 and IL-12 in activating the anticancer immune response in humans, cancer-related physiopathology of their secretion needs to be better investigated. IL-2 blood levels have been proven to decrease in the advanced neoplastic disease, whereas preliminary data would suggest an enhanced secretion of IL-12 in metastatic cancer patients. This study was performed to analyze IL-2 levels in relation to those of IL-12 in metastatic solid neoplasms. The study included 40 untreated metastatic cancer patients. Serum levels of both IL-2 and IL-12 were measured by ELISA. Abnormally low blood levels of IL-2 and elevated values of IL-12 were observed in 16/40 and in 18/40 patients, respectively. Moreover, patients with IL-2 deficiency showed significantly higher mean levels of IL-12 than patients with normal values of IL-2. This preliminary result, by showing an increased secretion of IL-12 in advanced cancer patients with IL-2 endogenous deficiency, would suggest the existance of a possible feedback mechanism operating between macrophage release of IL-12 and T lymphocyte secretion of IL-2.

Abstract
Hypotension is a frequent side-effect of cancer biotherapies with cytokines. Cytokine-induced hypotension would mainly depend on the stimulation of nitric oxide (NO) production, which represents the most effective endogenous vasodilator. Moreover, it has been proven that both biological activity and toxicity of cytokines are influenced by the psychoneuroendocrine system, in particular by the pineal hormone melatonin. To investigate the possible modulatory effect of melatonin on cytokine cardiovascular toxicity, we evaluated the influence of a concomitant melatonin administration on interleukin-2(IL-2)- and tumour-necrosis-factor-alpha(TNF)-induced hypotension in advanced cancer patients. The study included 116 patients with advanced solid tumour, for whom no effective standard anticancer therapy was available, who underwent cancer biotherapy with IL-2 (3 x 10(6) IU/ day s.c. every day, 6 days/week for 4 weeks) or with TNF (0.75 mg/day i.v. for 5 days) as compassionate treatment for their disease. Patients were randomized to be treated with or without a concomitant melatonin administration (40 mg/day orally in the evening, starting 7 days prior to cytokine injection). The occurrence of hypotension was significantly less frequent in patients concomitantly treated by melatonin than in those who received the cytokine alone, during either IL-2: or TNF immunotherapy (IL-2; 11/45 versus 2/46, P < 0.05; TNF: 10/23 versus 1/12, P < 0.01). This study shows that melatonin may prevent hypotension occurring during cancer immunotherapy with IL-2 or TNF. Since the pineal hormone has appeared to inhibit the activity of NO synthase from the endothelial cells, we suggest that melatonin may prevent cytokine-induced hypotension by inhibiting NO production, which plays an essential role in inducing hypotension during IL-2 and TNF biotherapies.

Abstract
It is known that neoplastic cachexia shows metabolic characteristics different from other common causes of malnutrition, and that it is mainly due to an abnormal secretion of TNF, whose levels are often high in patients with advanced neoplasia. Previous clinical studies have suggested that the pineal hormone melatonin (MLT), which plays an essential role in the neuroendocrine regulation of biological systems, may improve the clinical status of advanced cancer patients and inhibit TNF secretion. To investigate the relationship between MLT, TNF and cancer-related weight loss, 100 untreatable metastatic solid tumour patients entered this study to receive either supportive care alone, or supportive care plus MLT (20 mg/day orally in the evening). Patients were observed for 3 months, and were considered evaluable when they were observed for at least 2 months. There were 86 evaluable patients, the other 14 patients having died from rapid progression of disease. The per cent of weight loss greater than 10% was significantly higher in patients treated by supportive care alone than in those concomitantly treated by MLT, with no difference in food intake (P < 0.01). Mean serum levels of TNF progressively increased in the supportive care group, but to levels that were not significantly different from pretreatment values. In contrast, TNF mean concentrations significantly decreased (P < 0.05) in patients concomitantly treated by MLT. These results suggest that the pineal hormone MLT may be effective in the treatment of the neoplastic cachexia by decreasing TNF blood concentrations.

Abstract
It has been demonstrated that surgery may induce immunosuppression. This finding could influence the clinical course of surgically treated cancer patients. Moreover, preliminary experimental studies have shown that a preoperative injection of IL-2, whose importance in generating the antitumor immune response is well known, may neutralize surgery-induced immunosuppression. At present, however, it is still unknown whether preoperative IL-2-induced immune improvement in the postoperative period may influence the prognosis of surgically treated cancer patients. The present study was performed to evaluate the prognostic impact of IL-2 presurgical therapy in advanced colorectal cancer patients. The study included 50 colorectal cancer patients, Dukes' stage D, who were randomized to be treated with or without IL-2 preoperatively (18.10(6) IU/day subcutaneously for 3 consecutive days). After surgery, all patients underwent chemotherapy with 5-FU and folates until disease progression. Postoperative mean numbers of lymphocytes, T lymphocytes, natural killer cells and activated lymphocytes were significantly higher in IL-2-treated patients than in controls. Moreover, the percent of lymphocytic and/or eosinophilic tumor infiltration was significantly higher in IL-2 group than in controls. Finally, both survival curve and the percent of survival at 1 year were significantly greater in patients pretreated with IL-2 than in controls. This clinical trial demonstrates that preoperative IL-2-induced neutralization of postoperative lymphocytopenia is associated with a prolonged survival time in advanced colorectal cancer patients.

Abstract
Despite its well documented unfavourable prognostic significance in several human diseases, including cancer, the cytokinic mechanisms responsible for an increased erythrosedimentation rate (ESR) still remain to be better analyzed and defined. The recent possibility to measure cytokine concentrations in the blood of patients has allowed us to explore the possible relation between ESR values and endogenous cytokine secretions. This preliminary study was performed to evaluate the relationship between ESR values and serum levels of IL-2 and IL-6, which represent the most important cytokines responsible for the activation and the suppression, respectively, of host anticancer immune reaction. The study included 33 consecutive solid tumor patients, 22 of whom showed distant organ metastases. Abnormally high values of ESR were present in 21 patients, including 18/22 metastatic patients and 3/11 nonmetastatic patients. Patients with elevated values of ESR showed significantly higher mean levels of IL-6 and significantly lower mean concentrations of IL-2 with respect to those found in patients with normal ESR values. These results would show that cancer-related increase in ESR values is associated with low levels of IL-2 and high levels of IL-6. Since IL-2 plays an essential role in the anticancer immunity and IL-6 may suppress the antitumor immune defenses, the evidence of low levels of IL-2 and high values of IL-6 in cancer patients with increased ESR values would explain the unfavourable prognostic significance of high ESR values in human neoplasms.

Abstract
The prognosis of brain glioblastoma is still very poor and the median survival time is generally less than 6 months. At present, no chemotherapy has appeared to influence its prognosis. On the other hand, recent advances in brain tumor biology have suggested that brain tumor growth is at least in part under a neuroendocrine control, mainly realized by opioid peptides and pineal substances. On this basis, we evaluated the influence of a concomitant administration of the pineal hormone melatonin (MLT) in patients with glioblastoma treated with radical or adjuvant radiotherapy (RT). The study included 30 patients with glioblastoma, who were randomized to receive RT alone (60 Gy) or RT plus MLT (20 mg/daily orally) until disease progression. Both the survival curve and the percent of survival at 1 year were significantly higher in patients treated with RT plus MLT than in those receiving RT alone (6/14 vs. 1/16). Moreover, RT or steroid therapy-related toxicities were lower in patients concomitantly treated with MLT. This preliminary study suggests that a radioneuroendocrine approach with RT plus the pineal hormone MLT may prolong the survival time and improve the quality of life of patients affected by glioblastoma.

Abstract
Several experiments have suggested that the pineal gland has an antitumor immunomodulatory action. Melatonin (MLT), the best known pineal hormone, has been shown to stimulate anticancer immune defenses during the night, corresponding to the period of its maximum blood levels, whereas it has no effect during the light phase of the day. At present, no study has been performed to investigate possible immunomodulating properties of other pineal indoles, such as 5-methoxytryptophol (5-MTL), whose circadian secretion would be opposite with respect to that of MLT, since it reaches its highest levels during the light phase of the day. In an attempt to analyze possible effects of 5-MTL on anticancer immunity, we have evaluated the action of 5-MTL (1 mg/ day orally at noon for 5 days) in 10 healthy volunteers on the two fundamental suppressive and immunostimulatory cytokines, consisting of IL-6 and IL-2, respectively. Serum levels of IL-2 and IL-6 were measured by an immunoradiometric method. Mean serum concentrations of IL-2 significantly increased on 5-MTL therapy, whereas those of IL-6 significantly decreased in response to 5-MTL. This preliminary study would suggest that the less known pineal indole 5-MTL, as well as MLT, has important immunomodulatory effects on cytokine secretions, including those involved in the antitumor immune response, by further confirming the essential role of the pineal as a central regulation of biological response modifier system. Several pineal alterations have been described in advanced cancer patients. According to the results of this study, the simultaneous administration of MLT during the dark phase and of 5-MTL during the light period of the day could further contribute to correcting pineal functions and to pilot the host anticancer immune reaction in an antitumor direction with respect to MLT alone.

Abstract
It has been demonstrated that breast surgery may induce prolactin (PRL) increase. Because of the potential stimulatory role of PRL on breast cancer cells, its postoperative increase may influence the prognosis of breast cancer patients. This study was performed to evaluate the influence of surgery-induced hyperprolactinemia on recurrence rate in operable breast cancer. The study included 250 consecutive breast cancer patients, clinical stage T1-3 N0-2M0, who were observed for a median follow-up of 72 months. Surgery-induced hyperprolactinemia occurred in 108/250 patients (43%). Irrespectively of node involvement, hormonal receptor, type of surgery and adjuvant therapies, the relapse rate was significantly higher in patients who had no surgery-induced hyperprolactinemia than in those with postoperative PRL increase (64/142 vs. 23/108; p < 0.001). This difference was also significant in relation to node status (N0:22/63 vs. 5/56, p < 0.001; N+:42/79 vs. 18/52, p < 0.05). The present study shows that a surgery-induced rise of PRL, despite its potential stimulation of cancer cell growth, is paradoxically associated with a longer disease-free survival in operable breast carcinoma in both patients with or without axillary node involvement. Moreover, this study suggests that the prognosis of node-negative patients who did not show postoperative hyperprolactinemia tends to be similar to that of patients with node involvement and surgery-induced PRL enhancement. Therefore, the lack of surgery-induced hyperprolactinemia would have to be grouped together with the unfavorable prognostic factors of breast cancer.

Abstract
At present, it is known that there are two main mechanisms responsible for cancer-related immunosuppression, mediated by macrophages and by TH2 lymphocytes. The relation existing between macrophage- and TH2-mediated immunosuppression still remains to be understood. The present study was performed in an attempt to establish which is the correlation existing in cancer patients between IL-10 and neopterin levels, which reflect TH2- and macrophage-mediated suppressive events, respectively. The study included 40 solid tumor patients and 60 healthy subjects as controls. Serum concentrations of neopterin and IL-10 were measured by the RIA method and by an immuno-enzymetric assay, respectively. Because of its possible production both by TH2 and macrophages, serum levels of IL-6 were also determined. Neopterin, IL-10 IL-6 mean concentrations were significantly higher in cancer patients than in controls. Mean values of both neopterin and IL-6 were significantly higher in metastatic patients than in those with locally limited disease. IL-10 mean levels were also significantly higher in patients with metastatic disease. IL-6 levels were significantly correlated with those of neopterin, whereas no correlation was found between neopterin and IL-10 values. This preliminary study would suggest that macrophage- and TH2-mediated immunosuppression may occur independently in solid tumors, and that it becomes more evident with disease progression.
