Abstract
Non-melanoma skin cancers are a common reality worldwide. The principal cause that determines the occurrence of these diseases is the exposition of the sun, which principally causes an alteration in the immune system. Therefore, it is possible that other forms of innate or acquired alterations of the immune system could favor the occurrence of non-melanoma skin cancers. For example, several studies have demonstrated that immunosenescence creates an immunosuppressive state that encourages the development of malignances, and new discoveries have noted the importance of T cells and in particular of T regulatory cells (Treg) and T receptor CD28 in this mechanism. Similar results are obtained analyzing the effect of immunosuppressive drugs. The importance of the immune system and its alteration in the genesis of non-melanoma skin cancers is fundamental for the creation of a new therapeutic and less invasive approach.

Abstract
The increased incidence of malignancies in elderly patients living in industrialized countries has led to both identify the causes that alter the normal homeostatic balance in elderly and designate the specific treatments. The progressive decline of the immune system (immunosenescence) involving cellular and molecular alterations impact both innate and adaptive immunity. The immunosenescence leads to increased incidence of infectious diseases morbidity and mortality as well as heightened rates of other immune disorders such as autoimmunity, cancer, and inflammatory conditions. Here, we summarize the knowledge on the major changes in the immune system associated with aging in primary lymphoid organs as well as a description of molecular mechanisms, and the impact on cancer development.

Abstract
INTRODUCTION During aging, dysregulated immune functions occur contributing to increased susceptibility to morbidity and mortality. However, these dysregulations are normally counterbalanced by continuous adaptation of the body to the deteriorative changes occurring over time. These adaptive changes well occur in healthy centenarians. DISCUSSION Both innate (natural) and adaptive (acquired) immune responses decline with advancing age. Natural killer (NK) and natural killer T (NKT) cell cytotoxicity, representing one of best models of innate immune response, decreases in aging as well as interferon-gamma (IFN-gamma) production by both activated types of cells. Both NK and NKT cell cytotoxicity and IFN-gamma production increase in very old age with respect to normal aging, especially by NKT cells bearing TCRgammadelta. The role played by zinc and metallothioneins (MT) is crucial because this affects NK and NKT cell development, maturation, and functions. In particular, some MT polymorphisms are involved in maintaining innate immune response and intracellular zinc ion availability in aging with thus a role of MT genetic background to escape some age-related diseases with subsequent healthy aging and longevity.

Abstract
While tumour incidence is known to augment with age, paradoxically tumour growth and metastasis were often found to proceed at a slower rate at late ages. This age-related biological behaviour of tumours actually imposes a differential therapeutic approach to the old cancer patient. Several mechanisms of the age-related reduced tumour progression have been demonstrated: decreased tumour cell proliferation, increased apoptotic cell death, decreased angiogenesis and anti-tumoural immune response changes. We postulated that it might be possible to design age-adjusted treatment modalities based on the mechanisms responsible for the reduced tumour progression rate in the aged. Based on these mechanisms, we compared the effect of different treatments (apoptosis-inducing agents, Hydrocortisone and Adriamycin, anti-angiogenic agent, TNP-470, and immunomodulators-Levamisole and BCG) on two experimental tumours (B16 melanoma and AKR lymphoma) growing in young and old mice. Most treatments showed, in both tumours, a higher inhibitory effect on tumours growing in old mice than on those developing in young ones, to our knowledge, a feature not described before for anti-tumoural agents. We suggest that designing ageing conditions in tumours of young patients might possibly alleviate neoplastic aggressiveness in these patients as well.

Abstract
Over the last few years there has been a growing interest in geriatric oncology, mainly because of the evidence that advanced age is the greatest risk factor for the development of cancer and that, since the elderly population is rapidly expanding, so too will the number of cancer patients. This forecast necessitates the development of new and more specific strategies for the prevention and cure of cancer in the elderly and as a result an ever-increasing need for oncologists, geriatricians and researchers to work closely together. The increased incidence of cancer in elderly people has been related to the age-associated changes occurring in the immune system, the so-called immunosenescence. This phenomenon is best characterised by a remodelling of the immune system, which appears early on and progresses throughout a person's life and mainly involves a decrease in cellular functions. This review aims to provide a rationale for the development of specific immunotherapeutic and immunopreventive regimens for the elderly. We also include a discussion on the influence that immunosenescence has on the growth of tumours and the effectiveness of immunogene therapy and cancer vaccination following a brief analysis of the age-related alterations of the cell populations involved in antitumour immunity.

Abstract
While tumor incidence increases with age, tumor growth and metastasis often proceed at a slower rate in aged organisms. The mechanisms underlying this age-related reduced tumor development may suggest therapeutic modalities appropriate for the aged. Decreased tumor aggressiveness in the old was shown to be related to altered immune response. Consequently, the aim of the present study was to assess whether cancer immunotherapy has an age-dependent effect. Only a few studies have compared cancer immunotherapy efficiency as a function of age, most showing lower inhibition in older animals. In the present study, we tested the effect of two immunomodulators, levamisole and BCG, on two tumors, B16 melanoma and AKR lymphoma, in mice of different ages. We demonstrated a higher efficiency of immunotherapy in aged as compared to young mice, particularly at low immunomodulator doses. While decreased T cell function during aging is apparently established, nonspecific immunity is more preserved or even enhanced in later life. We found an increased number of macrophages in tumors of old compared to young mice and an increase in MAC-1+ cells in old levamisole-treated compared to non-treated mice. The stronger therapeutic effect of this immunomodulator in old mice might thus be due to an increased macrophage-mediated anti-tumoral effect.

Abstract
Immunosenescence is defined as the state of dysregulated immune function that contributes to the increased susceptibility to infection, cancer and autoimmune diseases observed in old organisms, including humans. However, dysregulations in the immune functions are normally counterbalanced by continuous adaptation of the body to the deteriorations that occur over time. These adaptive changes are likely to occur in healthy human centenarians. Both innate (natural) and adaptive (acquired) immune responses decline with advancing age. Natural killer (NK) and natural killer T (NKT) cells represent the best model to describe innate and adaptive immune response in aging. NK and NKT cell cytotoxicity decreases in aging as well as interferon-gamma (IFN-gamma) production by both activated cell types. Their innate and acquired immune responses are preserved in very old age. However, NKT cells bearing T-cell receptor (TCR) gammadelta also display an increased cytotoxicity and IFN-gamma production in very old age. This fact suggests that NKT cells bearing TCRgammadelta are more involved in maintaining innate and adaptive immune response in aging leading to successful aging. The role played by the neuroendocrine-immune network and by nutritional factors, such as zinc, in maintaining NK and NKT cell functions in aging is discussed.

Abstract
Numerous studies have demonstrated the efficacy of cytokine gene-engineered tumor cells to induce tumor rejection and specific memory acquisition into syngeneic immunocompetent mice by activation of host-dependent antitumor responses. A progressive immune dysfunction, mainly involving thymus-dependent specific immunity, occurs during aging. In this study we evaluated whether the injection of IL-2 gene-transfected tumor cells in old mice causes an immune activation which results in tumor rejection and induction of specific immune memory as occurs in young animals. Young and old mice were inoculated with syngeneic parental mammary adenocarcinoma cells (TS/A p.c.) or with TS/A cells engineered to release IL-2 (TS/A-IL2). Three clones of TS/A-IL-2 cells were used producing low (30 U, B1.30), intermediate (3600 U, B6.3600), or high (6000 U, B4.6000) IL-2. While the B1.30 clone grew in 100% of mice, the B6.3600 and B4.6000 clones were promptly rejected in both young and old animals. In young mice, rejection was associated with a large neutrophil and macrophage infiltration, with a minor number of CD4+ and CD8+ lymphocytes. In old mice, neutrophils and macrophages were the main cells involved in tumor rejection whereas both CD4+ and CD8+ lymphocytes were scarcely present in tumoral infiltrate. A lower number of apoptotic tumor cells was found in TS/A-IL2-challenged old mice in comparison with young animals. To test whether the injection of TS/A-IL2 cells induced a specific immune memory, mice with no tumors after the challenge with B6.3600 and B4.6000 clones received a lethal challenge of TS/A p.c. 90% and 30% of young mice previously injected with B4.6000 or B6.3600 clones, respectively, rejected TS/A p.c. In old mice, B4.6000 cells did not confer protection, whereas only 10% of mice which received B6.3600 cells were able to reject TS/A p.c. Neither the graft of a young thymus or the adoptive transfer of young T lymphocytes to old mice induced specific immune memory for TS/A p.c. in old animals. These data suggest the necessity to refine antitumor vaccination procedures in aging.

Abstract
BACKGROUND The aim of the current study was to evaluate the in vitro effect of IL-12 on the natural cytotoxicity of peripheral blood mononuclear cells (PBMCs) obtained from patients who underwent adjuvant-based cisplatin polychemotherapy for advanced ovarian carcinoma. The authors also investigated amifostine, a cytoprotective agent that appears to protect against chemotherapy damage to healthy tissues, to determine its effects on natural immune function. METHODS Twenty-one women with advanced ovarian serous cystoadenocarcinoma who underwent adjuvant cisplatin-based polychemotherapy were included in the study, and 20 normal volunteer women matched for age served as controls. Six of the 21 women who underwent polychemotherapy received 1:3 amifostine pretreatment. Blood samples were obtained immediately before the first cycle of cisplatin-based polychemotherapy and within 24 hours after the completion of polychemotherapy infusion to evaluate the natural cytotoxic activity of PBMCs against the K562 cell line and the in vitro responsiveness of cytotoxic cells to interleukin-12 (IL-12). RESULTS The in vivo administration of cisplatin-based polychemotherapy significantly reduced the natural killer cytotoxicity of PBMCs toward undetectable levels (2.2+/-3.1 vs. 9.2+/-7.0 lytic units, respectively, after and before cisplatin; P < 0.01), and the in vitro exposure to IL-12 did not increase the cytolytic activity of PBMCs (1.9+/-2.1 lytic units). PBMCs from the 6 patients who received random amifostine pretreatment were shown to have retained natural killer cytotoxicity after in vivo administration of cisplatin polychemotherapy (9.7+/-6.7 vs. 9.6+/-6.0 lytic units, respectively, after and before cisplatin; P = 0.9), and the incubation with IL-12 increased cytotoxic activity (13.4+/-6.9 lytic units) toward the levels observed in PBMCs of controls (14.0+/-4.6 lytic units). CONCLUSIONS These data suggest that cisplatin-based polychemotherapy reduces the natural cytotoxicity of PBMCs in patients with advanced ovarian carcinoma as well as their in vitro responsiveness to IL-12 incubation. Amifostine demonstrated a protective effect on natural killer cell cytotoxicity and responsiveness to IL-12 in this small cohort of patients.
