Abstract
Tumor spread may be favored by a reduced production and/or an enhanced degradation of extracellular matrix components (collagen, fibronectin, laminin). Most tumor cell behavior, from growth to spread, may be regulated by cytokines, the exact roles of which, however, are not yet fully understood. We here evaluate the effects of some cytokines (epidermal growth factor, transforming growth factor-beta 1, interleukin-1 alpha, and interleukin-1 beta) on both cell growth and the production of the aminoterminal peptide of type III procollagen, the urokinase plasminogen activator, and the plasminogen activator inhibitor-1 in neoplastic cell lines originating in the pancreas and colon. Cells were stimulated daily with the above cytokines and the aminoterminal peptide of type III procollagen, urokinase plasminogen activator, and plasminogen activator inhibitor-1 were measured in the conditioned media. Epidermal growth factor stimulated cell growth of both cell lines. Transforming growth factor-beta 1 counteracted cell proliferation and stimulated type III procollagen and plasminogen activator inhibitor-1 production only in the colon cancer cell line. Interleukin-1 alpha slightly stimulated cell growth, but inhibited plasminogen activator inhibitor-1 production in both cell lines; interleukin-1 beta did not affect cell growth, but stimulated plasminogen activator inhibitor-1 production by the colon cancer cell line. Our findings suggest that transforming growth factor-beta 1 and interleukin-1 beta may have an antidiffusive effect. These results confirm that cytokine-producing cells have a potential role in stimulating or counteracting tumor growth and spread and also confirm the pivotal role of host-tumor interactions in determining the outcome of a particular neoplasia.

Abstract
We evaluated levels of insulin-like growth factor-I and interleukin-1 alpha and beta in patients with pancreatic cancer; the role of these substances in tumor spread and in hyperglycemia was also investigated. Thirty pancreatic cancer patients (21 with hyperglycemia) were compared with others with diseases causing hyperglycemia [liver cirrhosis (14 cases, 12 with hyperglycemia), chronic pancreatitis (20 cases, 12 with hyperglycemia), type I diabetes mellitus (13 cases, all hyperglycemic)]. Insulin-like growth factor-I was significantly reduced in patients with liver cirrhosis, probably due to a reduced hepatic capacity for synthesis. It was increased in 6 of 30 pancreatic cancer patients; in these subjects it was correlated with alanine aminotransferase and C-peptide, but not with tumor diameter or the presence of metastases. Interleukin-1 alpha and beta were both elevated in pancreatic cancer patients. The former was high, while the latter was low when liver metastases were present. Neither was related to glucose or C-peptide levels. In summary, insulin-like growth factor-I levels are increased in some pancreatic cancer patients but this does not seem to favor tumor spread; however IGF-I could be involved influencing glucose homeostasis. Interleukin-1 alpha increased, while interleukin-1 beta decreased in pancreatic cancer patients with metastases, suggesting a different involvement of these two substances in pancreatic cancer spread.

Abstract
BACKGROUND Human interleukin-1 beta (hIL-1 beta) injected intratumorally has demonstrated growth inhibition of transplanted subcutaneous tumors in mice, regression of metastatic lesions, resistance to tumor rechallenge, and increased survival. Vaccinia virus (VV) can be genetically engineered to produce cytokines and may be an effective vector for gene therapy of cancer. This study was designed to (a) construct a VV expressing hIL-1 beta, (b) assess tumor cell infection in vitro with this construct, (c) measure hIL-1 beta production, and (d) assess the bioactivity of the secreted cytokine. METHODS The hIL-1 beta gene was amplified from a plasmid clone using polymerase chain reaction (PCR) and then cloned into a homologous recombination (HR) and expression vector, which was used to insert the hIL-1 beta gene into the VV genome. Selection of the recombinant VV (vMJ601hIL-1 beta) was based on inactivation of viral TK and expression of beta-galactosidase. vMJ601hIL-1 beta infectivity and cytokine production was assessed by infecting tumor cell lines and analyzing culture supernatants for hIL-1 beta. Bioactivity of the hIL-1 beta produced was demonstrated using an IL-1 dependent T helper cell line. RESULTS The hIL-1 beta gene was successfully cloned into the VV genome by HR, which was confirmed by PCR. vMJ601hIL-1 beta efficiently infected tumor cells, as shown by increased hIL-1 beta secretion (0 to > 500 ng/ml) and morphologic evidence of viral cytopathic effect. vMJ601hIL-1 beta-infected cells secreted large amounts of hIL-1 beta (mean 772 ng/10(6) cells/24 h). The secreted hIL-1 beta was bioactive (mean bioactivity 6.8 x 10(8) U/mg of hIL-1 beta). CONCLUSIONS (a) hIL-1 beta can be cloned into VV, (b) vMJ601hIL-1 beta retains its infectivity, (c) a large amount of hIL-1 beta is secreted, and (d) the secreted hIL-1 beta is bioactive. Recombinant VV may allow in situ cytokine gene delivery and expression in established tumors.

Abstract
Intraperitoneal (i.p.) treatment of MOPC104E ascitic tumor-bearing BALB/c mice with interleukin-1 (IL-1) followed by a low dose of cyclophosphamide (CPA) resulted in synergistic prolongation of their survival time. This antitumor effect was abolished when administration of CPA preceded that of IL-1. The combined i.p. therapy also eradicated subcutaneous (s.c.) tumors, indicating a systemically operating antitumor mechanism. In Winn assay, splenocytes from MOPC104E-bearing mice treated with the combined therapy completely suppressed the growth of MOPC104E cells, but not that of another syngeneic tumor cell line, RL female-8 cells. This tumor-neutralizing activity was completely abrogated by treatment with anti-asialo-GM1 or anti-Thy1.2 and complement, and reduced by treatment with anti-Lyt2.2 and complement. Treatment of splenocytes with 1-leucine methyl ester (Leu0Me), which depletes natural killer (NK) cells and macrophages in vitro, did not affect the neutralizing activity.

Abstract
The antitumor effects of biological response modifiers (BRMs) in an experimental mouse model, the "double grafted tumor system" were analyzed. Male BALB/c mice received simultaneous inoculations of Meth-A fibrosarcoma cells on the right flank (10(6) cells) and left flank (2 x 10(5) cells) on day 0, and BRMs were injected intratumorally into the right tumor on days 3, 4 and 5. PSK (a protein-bound polysaccharide preparation), interleukin-1 (IL-1) and cepharanthin (CR) cured not only the right, but also the left, non-treated tumor in a double grafted tumor system. OK-432 (a Streptococcus preparation) and BCG and tumor necrosis factor (TNF) cured the right tumor and inhibited the growth of the left tumor. Lentinan (a polysaccharide preparation) and IL-6 inhibited neither the right nor the left tumor. Immunosuppressive acidic protein (IAP) in serum was increased transiently soon after intradermal injection of PSK, CR, OK-432 and TNF in BALB/c mice. Lentinan, however, did not induce IAP. IAP in serum was gradually increased after intradermal inoculation of Meth-A tumor in BALB/c mice. The biochemical difference between PSK-induced IAP (early, inflammatory IAP) and Meth-A-induced IAP (late, tumor-induced IAP) was investigated by crossed affinity immunoelectrophoresis with concanavalin A. IAP of murine serum was separated into 4 peaks. IAP in normal mouse was rich in high-mannose type sugar chain (Peak 3) and contained no hybrid-type sugar chain (Peak 4), which was present in inflammatory and tumor-induced IAP. Inflammatory IAP was rich in biantennary sugar chain (Peak 2) and tumor-induced IAP was rich in tri-tetraantennary sugar chain (Peak 1).

Abstract
The outcome in 31 patients with liver metastases from breast cancer given OK-432-combined adoptive immunotherapy via the hepatic artery was analyzed. Patients received intraarterial OK-432, a streptococcal preparation, followed by the transfer of autologous lymphocytes cultured with autologous tumor extract and interleukin-2 for 9-13 days. Liver lesions were evaluable in 11 of the 12 patients with bone metastasis (group A) and in 16 of the 19 patients without bone metastasis (group B). Complete response (CR) in the liver was attained in 8 patients in group A, but in only 1 in group B (p < 0.01). In group A, radiological features of all metastatic foci of bone improved after CR in the liver. Moreover, the median survival time (MST) of group A (20 months) was longer (p = 0.06) than that of group B patients with extra-hepatic metastasis (n = 12; MST = 6 months), while group B patients with liver metastasis alone (n = 7) showed a MST similar to that of group A. Thus, loco-regional immunotherapy via the hepatic artery was found to be useful in controlling both liver and bone metastasis from breast cancer. Moreover, in breast cancer patients with liver metastasis, bone metastasis appears to be a prognostic factor associated with good response to this immunotherapy.

Abstract
The therapeutic efficacy and toxicity of three biological response modifiers, Corynebacterium parvum (Cp), Chinese blister beetle extract (CBBE), recombinant human IL-1 alpha (rhIL-1 alpha), used alone or in combination with chemotherapy or radiotherapy, were investigated in the intracerebral (ic) rat 9L brain tumor model. Used alone, Cp (2 mg/rat, ip plus 70 micrograms/rat, ic), CBBE (5 microliters of an ethanol extract, ic), or IL-1 alpha (1 microgram/rat, ic or 1 microgram/rat x 3, q 3 d, ic), had no effect on animal survival compared to the untreated or saline treated controls. When combined with chemotherapy or radiotherapy, the three immunotherapeutic agents did not show any additive effects on survival compared to that observed with systemic BCNU (12 mg/kg), local ic bleomycin (0.25 unit), or local radiotherapy (16 Gy). While ic IL-1 alpha did not produce evident toxicity, there was fatal toxicity caused by ic Cp or CBBE treatment in a few animals. The combination of Cp and bleomycin produced severe neurotoxicity, resulting in the early death of animals. This study demonstrates a lack of efficacy of the nonspecific immune adjuvants IL-1 alpha, Cp or CBBE, used either alone or combined with cytotoxic chemotherapy or radiotherapy, in this rat brain tumor model.

Abstract
Local adjuvant therapy of weakly immunogenic tumors protects against primary tumor challenge. However, this form of therapy does not produce long-lasting immunity to the tumor. In this study, local adjuvant therapy combined with systemic IL-1 administration produced not only primary tumor protection, but also long lasting immunity to the tumor. IL-1 and adjuvant protected animals resisted rechallenge with tumor as much as 180 days after initial tumor administration. Resistance to tumor rechallenge was IL-1 dose dependent. IL-1 and adjuvant protected animals also exhibited delayed type hypersensitivity reactions which were tumor-specific. Splenic and lymph node cell populations from IL-1 and adjuvant protected animals mounted tumor-specific lymphoproliferative responses. No such responses were observed in animals which had been administered either IL-1 or adjuvant alone. These results demonstrate that systemic IL-1 functions to augment specific immune protection when administered in conjunction with local adjuvant, resulting in long-lasting tumor immunity.

Abstract
The antitumor effect of PSK, a Coriolus preparation, was analyzed with the double grafted tumor system in which BALB/c mice received intradermal inoculations of syngeneic Meth-A fibrosarcoma in the right (primary tumor, 10(6) cells) and left (distant tumor, 2 x 10(5) cells) flanks. Intratumoral administration of PSK significantly inhibited the growth of not only the right but also the left tumor. PSK also inhibited the growth of a methylcholanthrene-induced fibrosarcoma BAMC-1, and a methylurethane-induced adenocarcinoma Colon 26 in the double grafted tumor system of syngeneic BALB/c mice. However, when the left distant tumor was different from the right Meth-A tumor, the intratumoral administration of PSK in the right tumor was unable to inhibit the growth of the left BAMC-1 or RL male-1 tumor. The PSK-induced immunity, therefore, is tumor-specific and T lymphocytes may play an important role in antitumor memory function. The enhancement of concomitant immunity by PSK treatment was completely impaired by previous intravenous administration of an alkylating agent, cyclophosphamide (CY). The enhancement of sinecomitant immunity by PSK treatment was also impaired by previous CY intravenous administration. The antitumor effect of PSK was suppressed by previous intravenous administration of another alkylating agent, ACNU. It is possible that alkylating agents suppress the function of effector T cells and granulocytes which are very important for the antitumor immune cascade reaction due to PSK treatment. On the other hand, the antitumor effect of PSK was enhanced by previous intravenous administration of an anti-metabolite, 5-fluorouracil.

Abstract
Recombinant human interleukin-1 beta (IL-1 beta) inhibited the growth of not only the right, but also the left non-treated tumor in a double grafted tumor system. Since the antitumor activity of IL-1 beta against the right and left tumors was not seen in nude mice, lymphocytes have a key role in the antitumor effect of intratumoral administration of IL-1 beta. TIL (tumor-infiltrating leukocytes) obtained from left and right side tumors treated with IL-1 beta were examined by Winn assay for their antitumor activity against Meth-A sarcoma in BALB/c mice. TIL from the right side clearly inhibited the growth of admixed Meth-A cells, but control TIL did not. Spleen cells and right and left regional lymph node cells prepared from IL-1-treated mice were examined for Lyt-1, Lyt-2 and L3T4 phenotypes. The number of Lyt-1-positive lymphocytes increased in the spleen and in the right regional lymph nodes after intratumoral administration of IL-1. Isolated tumor cells obtained from the right tumor treated with IL-1 beta and the left side tumor on day 6 were cultured in RPMI 1640 with 10% fetal calf serum for 24 h. The culture supernatants were harvested and tested for the presence of chemotactic activity for neutrophils or macrophages. Significant neutrophil chemotactic factor and macrophage chemotactic factor activities were detected in the culture media from IL-1-treated tumor tissues cultured for 24 h. Neither significant neutrophil nor macrophage chemotactic activity was detected in the media from untreated tumor tissues. These results suggest that intratumoral administration of IL-1 first induces neutrophils and macrophages in the right tumor, then Lyt-1-positive cells in the right regional lymph nodes and in the spleen, and subsequently induces macrophages in the left, non-treated tumor.

Abstract
Macrophages were harvested from home cage control (HCC) mice, and from mice which had been stressed by repeated brief exposures (3-8 min) to cold water at 10-15 degrees C twice daily for 8 or 14 days. Macrophages obtained from mice stressed 8 or 14 days compared to macrophages from HCC mice showed in vitro increased amounts of membrane-bound prothrombinase activity, whereas the thrombin degradation activity was unchanged. Furthermore, macrophages of mice stressed 8 days showed increased release of coagulation factor X/Xa to supernatant in vitro. These findings suggest an increased amount of prothrombinase complex enzymes on the surface of macrophages from mice stressed 8 days, and increased activity of the prothrombinase enzyme in macrophages from mice stressed 14 days. The synthesis of proteoglycans (PG) and glycosaminoglycans (GAG) was increased in macrophages from mice stressed 8 days compared to macrophages from HCC mice and mice stressed 14 days. When macrophages from mice stressed 8 days or HCC mice were stimulated in vitro with phorbol myristate acetate (PMA) and IL-1 or PMA and IL-2, a changed PG/GAG synthesis was observed only in macrophages from the HCC animals. Furthermore, both the tumour cytotoxicity and the released tumour necrosis factor (TNF) were decreased from macrophages from mice stressed 14 days compared to HCC mice. The results suggest that the macrophages of stressed mice have an altered mode of function more complex than a simple general suppression or activation.

Abstract
Mice stressed daily by brief cold water immersions for 1, 8 or 14 days showed changes in immune system function which were dependent on the number of mice per cage, frequency of stress exposures and total number of stress exposures. Changed percentages of spleen B and CD4, but not of CD8 cells were determined when the mice were stressed either once or twice daily. With CD4 cells, increased percentages were seen after stress once daily but a decreased percentage was seen after stress twice daily. Furthermore, the Concanavalin A-stimulated spleen cell mitogenesis was decreased after 1 day of stress in mice stressed once daily as opposed to after 8 and 14 days of stress in mice stressed twice daily. After 14 days of stress, the lipopolysaccharide stimulated mitogenesis was increased if the mice were stressed once daily but decreased if the mice were stressed twice daily. With two mice per cage, we observed a decreased spleen cell mitogenesis after 14 days of stress. With four mice per cage, the spleen cell mitogenesis was decreased after 8 and 14 days of stress. If spleen cell populations from mice stressed twice daily for 8 days were depleted of macrophages and CD4 or CD8 cells, the effect of stress on the mitogenesis was removed from the CD8 cells. Spleen cells of mice stressed for 14 days showed a decreased mitogenesis when depleted of adherent cells and reconstituted with adherent cells from control mice. Furthermore, the adherent cells from these mice had decreased ability to support mitogenesis of adherent cell-depleted spleen cells from control mice as well as a decreased IL-1 production.

Abstract
The antitumor effect of PSK, a Coriolus preparation, at a distant site was analyzed with the use of a double grafted tumor system in which male BALB/c mice received simultaneous intradermal inoculations of Meth-A tumor in the right (10(6) cells) and the left (2 x 10(5) cells) flanks and were then injected with PSK in the right tumor on the third day thereafter. The antitumor effect of intratumoral administration of PSK in the right tumor on days 3, 4 and 5 was compared with the effect of surgical resection of the right tumor on day 5. Three out of 8 mice given PSK intratumorally became tumor-free whereas no mouse tumor-free in the left flank was found among the surgically resected mice. As regards sinecomitant immunity, tumor inoculation into the right flank followed by intra-tumoral administration of PSK on days 3 and 5 and surgical excision of the primary tumor on day 6 resulted in complete rejection of a tumor challenge in the left flank on day 21. The combination of presurgical intratumoral injections of PSK (more than 2 times) and postoperative oral administration of PSK appeared to be most effective in eradicating secondary tumors. Isolated TILs (tumor-infiltrating lymphocytes), obtained from the right tumor (treated with PSK) and the left tumor on day 10 in the double grafted tumor system were cultured in RPMI1640 with 10% fetal calf serum for 24 h. The culture supernatants were harvested and tested for the presence of chemotactic activity for neutrophils or macrophages. Significant neutrophil chemotactic factor (NCF) and macrophage chemotactic factor (MCF) activities were detected in the culture media from PSK-treated TILs that had been cultured for 24 h. Neither significant neutrophil nor macrophage chemotactic activity was detected in the media from untreated TILs. NCF and MCF activities were also detected in the culture supernatant from PSK-treated tumor tissue on day 6. PSK-induced NCF in the murine tumor was neutralized by treatment with anti-human IL-8 IgG, and might be murine IL-8-like factor. Therefore, neutrophil and macrophage infiltrations of tumors following intratumoral injections of PSK are probably mediated by inductions of IL-8-like factor and MCF.

Abstract
Antitumor activity of recombinant human interleukin 1 alpha (IL-1) against seven human non-Hodgkin lymphomas grown in athymic nude mice was studied. Growth of the lymphomas was markedly inhibited after an injection of 0.4 mg/kg IL-1. The growth inhibition of Burkitt lymphoma was found to be dose-dependent up to 0.4 mg/kg, reaching a plateau thereafter. The loss of colony-forming ability of the cells and the loss of cell viability showed the same type of dose-dependence and progressed during 24 h following an injection of IL-1. In accordance with these observations, histopathologic examination revealed progressively spreading coagulative necrosis without bleeding. Little infiltration of inflammatory cells into the tumor tissue was observed. IL-1 growth inhibition of T lymphoma in beige nude mice having low natural killer activity was similar to that in nude mice. These findings suggested that the antitumor effects might not be produced through cell-mediated antitumor actions. Immunocytological examination with anti-IL-1 antibody revealed that administered IL-1 was bound to the lymphoma cells, suggesting that IL-1 receptor is probably expressed on these cells in vivo. The antitumor action of IL-1 on the lymphomas may be exerted directly through the IL-1 receptor.

Abstract
In order to investigate the antitumor effect of recombinant human interleukin-1 beta (IL-1 beta) alone and in combination with natural human tumor necrosis factor-alpha (nHuTNF-alpha), we used female BDF1 mice bearing Lewis lung carcinoma (3LL). IL-1 beta showed an antiproliferative effect against pulmonary metastatic tumors of 3LL in a dose-dependent manner. We observed 19.6 +/- 6.6, 18.6 +/- 5.3, 14.1 +/- 4.4 and 13.0 +/- 6.0 metastatic tumors at doses of 0.5, 1.0, 2.5 and 5.0 micrograms IL-1 beta/mouse/day by daily intravenous administration (the number of metastatic tumors of the control group was 26.3 +/- 8.2). Similar results were obtained by intraperitoneal administration, but in this case, mice showed a marked decrease of body weight. When IL-1 beta was administered in combination with nHuTNF-alpha, pulmonary metastatic tumors decreased much more than when IL-1 beta was administered alone. When the control group had 18.6 +/- 12.7 metastatic tumors, the nHuTNF-alpha group had 12.3 +/- 3.9 and the IL-1 beta group had 12.8 +/- 8.0, the group which was administered both cytokines had a significantly decreased number of 5.6 +/- 3.3 metastatic tumors. This antiproliferative effect of IL-1 beta in combination with nHuTNF-alpha was reduced by the intravenous administration of anti-asialo GM1 antibody and carrageenan. The number of metastatic tumors was increased from 8.9 +/- 8.0 to 18.8 +/- 11.4 by anti-asialo GM1 antibody and from 9.5 +/- 6.8 to 28.0 +/- 12.3 by carrageenan. It was suggested that asialo GM1-positive cells and macrophage were two of the most important effectors of the antiproliferative effect of IL-1 beta and TNF-alpha.

Abstract
In vivo administration of rHuIL-1 beta selectively enhanced the recovery from granulocytopenia and thrombocytopenia caused by sublethal irradiation or 5-FU treatment. Granulopoiesis and thrombopoiesis were stimulated by rHuIL-1 beta in a dose-dependent manner at doses ranging from 0.1 to 100 micrograms/kg. In this study, we have observed IL-1 to induce at least two distinct types of hematopoietic growth factors in vivo, namely GM-CSF and a thrombopoietin-like factor. Various kinds of CSFs alone did not stimulate colony formation of primitive hematopoietic progenitor cells obtained from 5-FU treated mice. However, the pretreatment of primitive hematopoietic progenitor cells with IL-1 in vitro or in vivo for 5 days accelerated the recovery of a cell population which respond to several types of CSFs. These data suggest that IL-1 may be useful clinically to enhance the recovery of granulocytes and platelets in myelosuppressed patients. In addition, we observed that rHuIL-1 beta is directly cytostatic for certain tumor cells in vitro. Intratumoral or subcutaneous injection of rHuIL-1 beta caused regression of a subcutaneous murine sarcoma by augmenting host antitumor responses. Together with the profound effects on hematopoiesis, these results point to potentially important uses of IL-1 beta in treatment of disease.
