The newer and potent immunosuppressive agents have successfully reduced the risk of rejection after kidney transplantation, but the development of cardiovascular diseases, infections, and malignancy is major factors limiting their success. Posttransplantation malignancy is the second most common cause of death in renal transplant recipients after cardiovascular disease; it is expected that mortality due to malignancy may become the most common cause of death within the next two decades. This study is designed to evaluate the incidence, risk factors, and types of malignancies occurring after renal transplantation and their impact on patient and graft survival...

Cutaneous squamous cell carcinoma (cSCC) is the most common metastatic skin cancer. Inflammation is a typical feature in cSCC progression. Analysis of the expression of inflammasome components in cSCC cell lines and normal human epidermal keratinocytes revealed upregulation of the expression of AIM2 mRNA and protein in cSCC cells. Elevated levels of AIM2 mRNA were noted in cSCCs in vivo compared with normal skin. Strong and moderate tumor cell specific expression of AIM2 was detected with immunohistochemistry (IHC) in sporadic human cSCCs in vivo, whereas expression of AIM2 was moderate in cSCC in situ (cSCCIS) and low or absent in actinic keratosis (AK) and normal skin...

The effects of immunodepression on several disease states have constituted an important area of research, leading to the identification of relevant associations between immunodepression and a vast set of comorbidities, including infectious diseases, cardiovascular diseases and cancer. Research on the effects of immunodepression has mostly been conducted in individuals under immunodepression by the human immunodeficiency virus and transplant recipients under pharmacological immunosuppression, due to the difficulties in obtaining relevant samples sizes in other contexts of immunodepression...

Unlike in Western countries, chronic lymphocytic leukemia (CLL) is a rare lymphoid malignancy in Japan, and its clinical features remain to be elucidated in the Japanese population. Therefore, we retrospectively analyzed 29 Japanese CLL patients newly diagnosed at our institute. Seventeen (59%) were male, and their median age was 62 years. With a median follow-up period from diagnosis of 69 months (range, 3-170 months), 9 patients received some form of treatment for CLL. Three patients died of disease progression with or without infection (n=2) or skin cancer (n=1)...

Nicotinamide is the precursor of nicotinamide adenine dinucleotide (NAD+), an essential cofactor for adenosine triphosphate (ATP) production. It has recently been reported to be effective in reducing the rates of new non-melanoma skin cancers (NMSCs) and actinic keratosis (AKs). We studied the efficacy of oral nicotinamide as treatment for AKs in transplant recipients. We recruited 38 transplant (eight liver and 30 kidney) patients with single or multiple AKs. Nineteen patients were randomly assigned to Group 1 and took nicotinamide 500 mg/daily (cases); the other 19 patients were randomly assigned to Group 2 without nicotinamide (controls)...

The risk of cancer is significantly increased in patients undergoing renal transplant surgery than in the general population. In particular, skin cancer is the most commonly occurring cancer in these patients.A 34-year-old man underwent living renal transplantation for focal segmental glomerulosclerosis. After 18 months, he developed a lesion on the nasal dorsum, approximately 1 cm in size, and the lesion rapidly expanded to cover the entire dorsum.Owing to its rapid expansion, the lesion was suspected to be a malignant tumor and wide excision was planned...

Renal transplantation is the most frequently performed transplant procedure. Immunosuppressive therapies have dramatically increased survival rates in transplant recipients but are associated with an increased risk of skin cancers. Recent changes in immunosuppressive strategies have been adopted with the aim of reducing this challenging adverse effect. Despite these new strategies, cutaneous malignancies tend to be numerous, aggressive and associated with a higher risk of local and distant dissemination than in the non-transplant population...

BACKGROUND: The first human lung transplantation was performed by James Hardy in 1963 due to lung cancer. Currently, malignancy has its importance in the follow-up of transplanted patients because cancer risk is higher in this population and the main risk factor for this augmentation is immunosuppression. The most common types of cancer are non-melanoma skin cancer and post-transplantation lymphoproliferative diseases. The objective of this study is to measure the cancer incidence and its related mortality in lung-transplanted patients of a Brazilian institution...

BACKGROUND: Chronic immunosuppression promotes Nonmelanocytic Squamous Cell Carcinoma (SCC) after kidney transplantation. Adaptive and innate immunity play a key role controlling tumor growth and are influenced by different immunosuppressive agents. We hypothesized that functional impairment of tumor-specific T cell responses due to CNI could contribute to SCC development, whereas conversion to mTOR-i could recover this protective immune response. METHODS: Peripheral tumor-specific T cell responses against main SCC-derived antigens using the IFN-γ ELISPOT assay and intratumor and circulating immune phenotypes (CD4+T, CD8+T, CD20+B, CD56+NK, FOXP3+Tregs) were explored in a cross-sectional analysis in 59 kidney transplant patients with SCC on CNI (KT-CNI-SCC) or mTOR-i (KT-mTORi-SCC), 25 nontransplants developing SCC (NoKT-SCC) and 6 healthy controls...

It is estimated that solid organ transplant recipients have a two- to fourfold greater overall risk of malignancy than the general population. Some of the most common malignancies after transplant include skin cancers and posttransplant lymphoproliferative disorder. In addition to known risk factors such as environmental exposures, genetics, and infection with oncogenic viruses, immunosuppression plays a large role in the development of cancer through the loss of the immunosurveillance process. The purpose of this article is to explain the role of immunosuppression in cancer and to review the classes of chemotherapeutics...

Merkel cell carcinoma (MCC) is an aggressive skin cancer entity that frequently leads to rapid death due to its high propensity to metastasize. The etiology of most MCC cases is linked to Merkel cell polyomavirus (MCPyV), a virus which is monoclonally integrated in up to 95% of tumors. While there are presently no animal models to study the role of authentic MCPyV infection on transformation, tumorigenesis or metastasis formation, xenograft mouse models employing engrafted MCC-derived cell lines (MCCL) represent a promising approach to study certain aspects of MCC pathogenesis...

Cancer risk is increased substantially in adult kidney transplant recipients, but the long-term risk of cancer in childhood recipients is unclear. Using the Australian and New Zealand Dialysis and Transplant Registry, the authors compared overall and site-specific incidences of cancer after transplantation in childhood recipients with population-based data by using standardized incidence ratios (SIRs). Among 1734 childhood recipients (median age 14 years, 57% male, 85% white), 289 (16.7%) developed cancer (196 nonmelanoma skin cancers, 143 nonskin cancers) over a median follow-up of 13...

There is a known increased risk of skin cancer in the adult population after hematopoietic stem cell transplantation (HSCT). However, late dermatologic effects that children may experience after HSCT have not been well described. The primary objective of this study was to characterize nevi and skin cancers affecting children after allogeneic HSCT. A cross-sectional cohort study of 85 pediatric HSCT recipients and 85 controls matched for age, sex and skin phototype was performed at a single institution. All participants underwent a full skin examination...
