BACKGROUND: Organ transplant recipients have an up to 250-times higher risk to develop skin cancer. This article evaluated the utilisation of skin cancer screening and the treatment costs for skin cancer in organ transplant recipients. Patients of the health insurance AOK Bremen/Bremerhaven had been identified and the need for skin cancer prevention trainings was derived. METHODS: The number of organ transplant recipients (ICD code Z94.0-4) with and without any history of skin cancer (ICD code C43/C44), the utilisation of dermatologic health care services, and the costs for treatments with the diagnosis Z94...

The case is presented of a post-lung transplant patient, ASA III, proposed for orchiectomy due to testicular cancer. A combination of iliohypogastric (ILH), ilioinguinal (ILI) and genitofemoral (GF) nerve block together with sedation was used as anaesthetic technique. The inguinal area received sensory innervation mainly from ILI, ILH and GF nerves. The genital branch of the GF nerve supplies innervation to skin of the anterosuperior portion of the scrotum. When performing the echo-guided block of GF nerve, it is necessary to identify the spermatic cord, and administer the local anaesthetic on the inside and periphery of the cord...

BACKGROUND: The role of sun exposure in the development of melanoma and non-melanoma skin cancers is known; however, there are limited data on the contribution of pre-transplantation total sun burden (TSB) to the increased skin cancer risk in organ transplant recipients (OTRs). The importance of patient education about sun-safe behaviours is understood, but educations are often unsuccessful in OTRs. METHODS: A questionnaire-based cross-sectional study was performed with kidney transplant patients at a single academic centre to assess the pre- and post-transplant sun-exposure, sun-protection habits and skin cancers...

Sclerodermatous graft-versus-host disease is a subtype of cutaneous chronic graft-versus-host disease that is characterized by sclerosis of the skin and subcutaneous tissue, resulting in debilitating contractures, among other life-threatening complications. Children with sclerodermatous graft-versus-host disease are at high risk of developing nonmelanoma skin cancer because of several risk factors, including young age at transplantation, prolonged immunosuppression, and exposure to photosensitizing antimicrobial prophylaxis such as voriconazole...

Infections with cutaneous papillomaviruses have been linked to cutaneous squamous cell carcinomas that arise in patients who suffer from a rare genetic disorder, epidermodysplasia verruciformis, or those who have experienced long-term, systemic immunosuppression following organ transplantation. The E6 proteins of the prototypical cutaneous human papillomavirus (HPV) 5 and HPV8 inhibit TGF-β and NOTCH signaling. The Mus musculus papillomavirus 1, MmuPV1, infects laboratory mouse strains and causes cutaneous skin warts that can progress to squamous cell carcinomas...

Merkel cell carcinoma (MCC) is a rare but aggressive skin cancer with frequent metastasis and death. MCC has a mortality rate of 30%, making it more lethal than malignant melanoma, and incidence of MCC has increased almost fourfold over the past 20 years in the USA. MCC has long been considered to be an immunogenic cancer because it occurs more frequently in immunosuppressed patients from organ transplant and HIV infection than in those with immunocompetent. Chronic UV light exposure and clonal integration of Merkel cell polyomavirus (MCPyV) are two major causative factors of MCC...

Chronic graft-versus-host disease (cGVHD) is characterized as autoimmune-like fibrosis and antibody production mediated by pathogenic T-cells and B-cells. MicroRNA (miR)-17-92 influences the survival, differentiation and function of lymphocytes in cancer, infections and autoimmunity. To determine whether miR-17-92 regulates T- and B-cell responses in cGVHD, we generated mice conditionally deficient for miR-17-92 in T-cells, B-cells, or both. Using murine models of allogeneic bone marrow transplantation (allo-BMT), we demonstrate that expression of miR-17-92 in donor T- and B-cells is essential for the induction of both scleroderma and bronchiolitis obliterans in cGVHD...

Many malignancies that occur in high excess in kidney transplant recipients (KTRs) are due to viruses that thrive in the setting of immunosuppression. Keratinocyte carcinoma (KC), the most frequently occurring cancer type in KTR, has been associated with skin infection by human papillomavirus (HPV) from the beta genus. In this report, we extend our previous investigation aimed at identifying the presence of active β-HPV infection in skin tumors from KTRs through detection of viral protein expression. Using a combination of antibodies raised against the E4 and L1 proteins of the β-genotypes, we were able to visualize infection in five tumors [one keratoacanthoma (KA), three actinic keratoses (AKs), and one seborrheic keratoses (SKs)] that were all removed from two patients who had been both transplanted twice, had developed multiple KCs, and presented with a long history of immunosuppression (>30 years)...

Second malignancies are a rare but well-defined late complication after autologous and allogeneic hematopoietic stem-cell transplantation (SCT). Solid malignancies occur in up to 15% of patients 15 years after SCT with myeloablative conditioning, with no plateau in the incidence rates. They are responsible for 5-10% of late deaths after SCT. The incidence is increased with advanced age at SCT. The major risk factors are the use of total body irradiation, which is associated with adenocarcinomas and with chronic graft-versus-host disease which is associated with squamous cell cancers...

Photodynamic therapy (PDT), using topically administered photosensitizing agents, is widely approved as a treatment for certain nonmelanoma skin cancers. As a tissue-sparing non-surgical modality, there is great potential for PDT to enhance the choice of therapies available to treat, and potentially prevent, skin cancer. Treatment-specific guidelines have assessed the evidence for various photosensitizing agents and light sources, dosimetry, and evaluate reported adverse effects. Discomfort is frequently experienced during treatment but no analgesia was required in most pivotal lesion-directed studies...

Importance: Squamous cell carcinoma (SCC) is the most common skin cancer diagnosed in solid organ transplant recipients (OTRs) and confers significant mortality. The development of SCC in the genital region is elevated in nonwhite OTRs. Viral induction, specifically human papillomavirus (HPV), is hypothesized to play a role in the pathophysiology of these lesions. Objective: To assess the prevalence and types of genital lesions observed in OTRs. Design, Setting, and Participants: This retrospective review included 496 OTRs who underwent full skin examination from November 1, 2011, to April 28, 2017, at an academic referral center...

PURPOSE: Non-melanoma skin cancer (NMSC) is the most common de novo malignancy in liver transplant (LT) recipients; it behaves more aggressively and it increases mortality. We used decision tree analysis to develop a tool to stratify and quantify risk of NMSC in LT recipients. METHODS: We performed Cox regression analysis to identify which predictive variables to enter into the decision tree analysis. Data were from the Organ Procurement Transplant Network (OPTN) STAR files of September 2016 (n = 102984)...

De-novo malignancies carry an incidence ranging between 3%-26% after transplant and account for the second highest cause of post-transplant mortality behind cardiovascular disease. While the majority of de-novo malignancies after transplant usually consist of skin cancers, there has been an increasing rate of solid tumor cancers over the last 15 years. Although, recurrence of hepatocellular carcinoma (HCC) is well understood among patients transplanted for HCC, there are increasing reports of de-novo HCC in those transplanted for a non-HCC indication...
