Abstract
Cancer morbimortality is still a great concern despite advances in research and therapies. Histamine and its receptors' ligands can modulate different biological responses according to the cell type and the receptor subtype involved. Besides the wide variety of histamine functions in normal tissues, diverse roles in the acquisition of hallmarks of cancer such as sustained proliferative signaling, resistance to cell death, angiogenesis, metastasis, altered immunity and modified microenvironment have been described. This review summarizes the present knowledge of the various roles of histamine H2 receptor (H2R) ligands in neoplasias. A bioinformatic analysis of human tumors showed dissimilar results in the expression of the H2R gene according to tumor type when comparing malignant versus normal tissues. As well, the relationship between patients' survival parameters and H2R gene expression levels also varied, signaling important divergences in the role of H2R in neoplastic progression in different cancer types. Revised experimental evidence showed multiple effects of H2R antihistamines on several of the cited hallmarks of cancer. Interventional and retrospective clinical studies evaluated different H2R antihistamines in cancer patients with two main adjuvant uses: improving antitumor efficacy (which includes regulation of immune response) and preventing toxic adverse effects produced by chemo or radiotherapy. While there is a long path to go, research on H2R antihistamines may provide new opportunities for developing more refined combination therapeutic strategies for certain cancer types to improve patients' survival and health-related quality of life.

Abstract
Histamine receptor 2 (H2R) blockade is commonly used in patients with gastric, duodenal ulcers or gastroesophageal reflux disease. Beyond the gastrointestinal tract, H2R is expressed by multiple immune cells, yet little is known about the immunomodulatory effects of such treatment. Clinical reports have associated H2R blockade with leukopenia, neutropenia, and myelosuppression, and has been shown to provide clinical benefit in certain cancer settings. To systematically assess effects of H2R blockade on key immune parameters, a single-center, single-arm clinical study was conducted in 29 healthy subjects. Subjects received daily high dose ranitidine for 6 weeks. Peripheral blood immunophenotyping and mediator analysis were performed at baseline, 3 and 6 weeks into treatment, and 12 weeks after treatment cessation. Ranitidine was well-tolerated, and no drug related adverse events were observed. Ranitidine had no effect on number of neutrophils, basophils or eosinophils. However, ranitidine decreased numbers of B cells and IL-2Rα (CD25) expressing T cells that remained lower even after treatment cessation. Reduced serum levels of IL-2 were also observed and remained low after treatment. These observations highlight a previously unrecognised immunomodulatory sustained impact of H2R blockade. Therefore, the immune impacts of H2R blockade may require greater consideration in the context of vaccination and immunotherapy.

Abstract
A recent randomized trial suggests that there may be an advantage in terms of survival with the combination of histamine and subcutaneous interleukin-2 (IL-2), compared to IL-2 alone. It has been postulated, then, that antihistamines may actually be antagonistic to IL-2 and, therefore, interfere with its antitumor activity. Because antihistamines such as cimetidine and ranitidine are commonly used as prophylaxis against gastrointestinal toxicity commonly seen with IL-2, and, because antihistamines may increase natural killer cell activity, it is reasonable to examine the response rate for this combination. An OVID Medline literature search between 1985 and 2003 was done. Continuous infusion (CIV) interleukin- 2 was used as the reference therapy because of the relatively constant IL-2 levels generated by this approach. Included studies were those in which either cimetidine, ranitidine, or famotidine were regularly scheduled and administered concurrently with IL-2, typically for gastrointestinal ulcer prophylaxis. Six (6) studies were identified. A total of 21 patients responded to therapy. Total response rate was 11%, with a 95% Confidence Interval: 7-17%. Four (4) complete responses were noted. Complete response rate was 2%, with a 95% Confidence Interval: 1-6%. These response rates are consistent with previously noted IL-2 response rates. In this retrospective review of CIV IL-2 and antihistamines, this combination appears to be active in melanoma. There appears to be no deleterious effect of routine antihistamine on the CIV IL-2 response rate.

Abstract
Clinical application of interleukin (IL)-2-based immunotherapy of cancer has been limited by a major side-effect known as 'capillary leak syndrome', resulting from nitric oxide (NO) overproduction. A galactoside-specific lectin from Viscum album L. (VAA) has been reported to induce certain lymphokines and upregulate IL-2 receptors on lymphocytes. Present study was, therefore, designed to compare the effects of combination therapy with IL-2 (10(4) Cetus units/mouse, intraperitoneal (i.p). every 8 h, given as 5 day rounds per week, for one or two rounds) and VAA (1 ng/kg subcutaneous (s.c.), biweekly) with those of IL-2 or VAA therapy alone in C3H/HeJ female mice bearing s.c. transplants of a highly metastatic C3L5 mammary adenocarcinoma. IL-2 therapy alone reduced tumour growth and metastasis, but caused significant water retention indicative of capillary leakage in the kidneys after both rounds of therapy, whereas pleural effusion was only evident after the first round and not the second round. A sharp rise in the systemic NO levels after the first round, followed by a decline after the second round of IL-2 therapy suggested a causal relationship of increased NO levels to pleural effusion. A strong immunostaining for nitrotyrosine (a marker for the production of peroxynitrite) was noted in the renal tubules at the end of both rounds of therapy suggestive of a causal association of this toxic NO-metabolite with capillary leakage in the kidneys. Addition of VAA to IL-2 therapy had no effect on any of the above parameters. Unexpectedly, however, VAA therapy alone stimulated tumour growth as well as lung metastases. NO induction in the C3L5 cells by VAA was excluded as a possible reason for this stimulation. Present results suggest the need for exercising caution in the use of VAA as an immunoadjuvant in human cancer therapy.

Abstract
As a result of preclinical data demonstrating the antitumour and antimetastatic efficiency of indomethacin in murine models, and the clinical observation of occasional tumour regression in patients with advanced melanoma treated with indomethacin together with ranitidine, a Phase II study was performed of prolonged administration of these two oral agents in combination. Seventeen patients were entered into the study and commenced on indomethacin 50 mg three times daily; the dose was escalated to a maximum of 75 mg three times daily in patients who tolerated the starting dose. Ranitidine was administered concurrently at a dose of 150 mg twice daily. One patient with uveal melanoma metastatic to the liver achieved a partial response, with slow shrinkage of a biopsy-proved liver metastasis (objective response rate 6 percent; 95 percent CI0-29). Another patient demonstrated a minor response in pelvic lymph nodes. The combination of indomethacin and ranitidine has negligible activity in advanced malignant melanoma; a response may require months to be achieved.

Abstract
Previous clinical studies have demonstrated a dose-response relationship between enhancement of certain immune parameters and interleukin-2 (IL-2) dose in trials with low dosages of the cytokine. This has not been demonstrated for high-dose (greater than 18 x 10(6) IU/m2 per day) IL-2. We completed phase II trials of sustained administration of indomethacin and ranitidine with IL-2 given as a continuous infusion over 5 days for three courses. Peripheral blood mononuclear cells, both fresh and cultured in vitro with IL-2 or IL-2 and indomethacin, were tested for tumoricidal function against K562 and Daudi targets; these results were then correlated with actual delivered dose and mean infusion rate per course. Similar correlations were calculated between delivered dose or infusion rate and absolute and proportional counts of lymphocyte subsets as determined by flow cytometry. No enhancement of in vitro tumoricidal function with either increasing delivered dose or increasing infusion rate was seen. No consistent pattern of correlation was found between the absolute counts of lymphocyte subsets after each course of IL-2 with delivered dose or infusion rate. The percent rise in absolute counts of selected T- and NK-cell subsets at the end of course 1 compared with baseline values correlated positively with infusion rate; however, a similar correlated between the infusion rate and an increase in lymphocyte tumoricidal function was lacking. Little evidence was found for improved tumoricidal function of mononuclear cells or consistent enhancement of lymphocyte subset counts in patients able to tolerate doses of IL-2 beyond 18 x 10(6) IU/m2 per day in a 5-day continuous infusion schedule.

Abstract
T-cell adjuvancy involves the use of agents to stimulate preferentially delayed type hypersensitivity (DTH). Traditional adjuvants like Alum, Freunds, muramyl peptides, and endotoxins are not selective. Natural infection (e.g. vaccinia) may yield selective DTH. Low dose cyclophosphamide (CY) with mycobacteria was the first experimental T-cell adjuvant. New adjuvant formulations (ISCOMS, MAPS, etc.) with synthetic T-cell epitopes offer improved formulations. Upregulation of TH-1 helper cells and their actions with interleukins like IL-2, IL-12, and gamma IFN or antibodies to IL-4 and IL-10 may augment potently pathogen and tumor resistance. Similarly, transfection of tumor target cells with genes for IL-2, IL-12, gamma IFN, etc., offers novel vaccine treatment approaches. Finally, "thymomimetic" peptides like thymosin alpha 1 or drugs like levamisole or isoprinosine alone or in conjunction with interleukins may augment TH-1 and DTH responses. These approaches are seeing increasing emphasis in new treatment strategies for cancer and infections like HIV.

Abstract
Histamine type-2 receptor antagonists (H-2RA) have been used chronically to prevent dyspepsia in cancer patients subjected to immunotherapy with chronic indomethacin (Indo) and intermittent IL-2 in our cancer centre. We tested the effects of these agents during immunotherapy of C3H/HeJ mice transplanted s.c. with 5 x 10(5) C3L5 mammary adenocarcinoma cells. Tumor-transplanted mice were divided into groups receiving: (1) Indo (14 micrograms/ml); (2) H-2RA, i.e. (a) ranitidine at 28.6 micrograms/ml (Ran-lo) or 143 micrograms/ml (Ran-hi), or (b) famotidine (Fam) at 4.3 micrograms/ml, or (c) cimetidine (Cim) at 107 micrograms/ml, all in the drinking water on days 5-24; (3) IL-2 (1.5 x 10(3) Cetus U i.p. every 8 h on days 10-14 and 20-24); (4) combinations of H-2RA + Indo; or (5) combinations of H-2RA + Indo + IL-2. Animals were killed on day 24 for examination of primary s.c. tumor growth, secondary lung metastasis and splenocyte cytotoxicity against YAC-1 lymphoma cells (51Cr release assay). Results revealed: (1) primary tumor growth was reduced in mice treated with Fam + Indo, Indo + IL-2 and any of the H-2RA + Indo + IL-2 (no difference observed within the last two groups); (2) lung metastases decreased in mice treated with IL-2 alone, Indo + IL-2, and Indo + IL-2 + Ran-hi; (3) splenic cytotoxicity was suppressed in tumor-bearing controls, with partial restoration seen in Ran (both doses), Ran-lo + Indo, Ran-lo + Indo + IL-2, and Cim + Indo + IL-2 treated groups. Nearly complete restoration was seen in Cim, Cim + Indo, Indo + IL-2, Ran-hi + Indo + IL-2, and Fam + Indo + IL-2 groups. Thus, addition of H-2RA did not alter the overall therapeutic efficacy of the standard Indo + IL-2 tumor immunotherapy.

Abstract
Experimental work in murine models has shown that, during the development of tumors, prostaglandin E2 produced by host macrophages inactivates natural killer cells and suppresses lymphokine-activated killer (LAK) cell development. Chronic indomethacin therapy when combined with interleukin-2 (IL-2) can totally eradicate experimental lung metastases in these models. A phase II trial was performed to study the clinical efficacy of chronic indomethacin and intermittent IL-2 therapy in patients with advanced renal cell carcinoma. Patients were placed on indomethacin and ranitidine orally at least one week prior to commencing therapy with IL-2. IL-2 was given by continuous infusion for three courses, each consisting of 5 days of treatment with 6 days of rest. Initial dose of IL-2 was 18.0 x 10(6) IU/m2/day for the first course with escalation to 27.0 x 10(6) IU/m2/day for the second and 36.0 x 10(6) IU/m2/day for the third course, if toxicity allowed. Patients were admitted to a general oncology ward for therapy with IL-2, and vasopressor agents were not used. Thirty-two patients were eligible, with 7 patients withdrawing early from the study. Twenty-five patients went on to receive at least one course of IL-2. Two complete and three partial responses were seen for an objective response rate of 5/25 (20%) for eligible and treated patients or 5/32 (16%) for all patients entered onto the study, regardless of treatment status. The response rate to this regimen is comparable with other high dose IL-2 regimens in renal cell carcinoma, including those employing adoptive therapy with lymphokine-activated killer cells.
