Sachedina D, Gibson F, Xia E, Walia A, Behara L, Fazelpour S, Mullins H, Francis J, Sahni D. Skin cancer in renal transplant recipients: outcomes from a safety net hospital in Boston. Int J Dermatol 2024; 63:1048-1055. [PMID: 38328999 DOI: 10.1111/ijd.17061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Revised: 01/10/2024] [Accepted: 01/12/2024] [Indexed: 02/09/2024]
Abstract
BACKGROUND Renal transplant recipients (RTRs) are prone to skin cancer due to the immunosuppression required to maintain graft function. Existing studies of skin cancer in RTRs focus on patients with Fitzpatrick skin types I-II, with limited documentation of incidence in skin types III-VI. This study seeks to better characterize skin cancers in RTRs with skin types III-VI. PRIMARY AIMS Compare the incidence of skin cancer in RTRs of skin types I-II with skin types III-VI. SECONDARY AIMS Explore the association between the development of skin cancer and other contributing factors in RTRs of skin types I-VI. METHODS Retrospective chart review of RTRs at a single institution between January 1, 2000 and December 31, 2022. Patients were followed from the date of transplant to the last clinical follow-up or death. 777 RTRs were included in the study, including 245 patients with Fitzpatrick skin types I-II and 532 with skin types III-VI. A total of 48 patients developed NMSCs, 2 patients developed melanoma, and 3 patients developed Kaposi sarcoma. RESULTS AND CONCLUSIONS There is a higher incidence of skin cancer in RTRs with Fitzpatrick skin types III-VI compared to the reported incidence among non-transplant recipients of the same skin types, but the incidence remains considerably lower compared to RTR of skin types I-II.

Abstract
BACKGROUND Human herpes virus 8 (HHV-8) or Kaposi sarcoma herpesvirus (KSHV) is an opportunistic oncovirus that causes multiple pathologic entities. METHODS We present a case of fatal HHV-8-associated multisystem illness with disseminated Kaposi sarcoma and HHV8-associated lymphoproliferative disorder with systemic inflammation. We conducted a narrative review of the literature on HHV-8 in transplantation with a goal of illuminating the spectrum of HHV-8-associated diseases in this vulnerable population, modes of disease transmission, and the potential role for donor and recipient screening. RESULTS HHV-8-associated KS, primary effusion lymphoma (PEL), multicentric Castleman disease (MCD), and KSHV inflammatory cytokine disorder (KICS) may affect transplant recipients; with the exception of KS, these conditions are rare but carry high morbidity and mortality. CONCLUSION HHV-8-associated diseases have diverse and protean manifestations in transplant recipients, with potentially fatal outcomes. HHV-8 seroprevalence among organ donors and the magnitude of risk for donor-derived HHV-8 infection or clinically significant disease remain unknown and require further study.

Immunosuppression and cancer risk in kidney transplant recipients: A retrospective cohort study. Int J Cancer 2024; 154:2043-2053. [PMID: 38345158 DOI: 10.1002/ijc.34875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 01/05/2024] [Accepted: 01/11/2024] [Indexed: 04/14/2024]
Abstract
We assessed whether contemporary immunosuppression agents were associated with cancer among kidney transplant recipients (KTR), and if this association varied by age and sex. We studied a retrospective province-wide cohort of primary KTR (1997-2016). Employing multivariable Cox models, we estimated associations of cumulative doses of prednisone, mycophenolate and tacrolimus administered over the past 10 years, lagged by 2 years, with the incidence of primary malignant neoplasms (PMN). We assessed interactions with age and sex. To assess the impact of exposure recency, we used weighted cumulative exposure (WCE) modeling. Among 1064 KTR, 108 (10.2%) developed PMN over median follow-up of 73 months (interquartile range: 32-120). Adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) of 0.96 (0.64-1.43), 1.34 (0.96-1.86), and 1.06 (0.88-1.29) were estimated for cumulative daily doses of prednisone (5 mg), mycophenolate (1000 mg), and tacrolimus (2 mg) administered continuously over the past 10 years, respectively. PMN risk associated with cumulative tacrolimus exposure was modified by age (interaction p = .035) and was more pronounced in 15-year and 30-year-old KTR (aHRs of 1.57 [1.08-2.28] and 1.31 [1.03-1.66], respectively) in comparison to older KTR. PMN risk increase associated with higher cumulative mycophenolate dose was more pronounced in females (aHR = 1.86 [1.15-3.00]) than in males (aHR = 1.16 [0.74-1.81]; interaction p = .131). WCE analyses suggested increased PMN risk the higher the mycophenolate doses taken 5-10 years ago. A trend toward increased PMN risk with long-term mycophenolate exposure, particularly in females, and more pronounced risk with long-term tacrolimus exposure in younger KTR, identify opportunities for tailored immunosuppression to mitigate cancer risk.

Abstract
Chemokines play a key role in cancer processes, with CXCL1 being a well-studied example. Due to the lack of a complete summary of CXCL1's role in cancer in the literature, in this study, we examine the significance of CXCL1 in various cancers such as bladder, glioblastoma, hemangioendothelioma, leukemias, Kaposi's sarcoma, lung, osteosarcoma, renal, and skin cancers (malignant melanoma, basal cell carcinoma, and squamous cell carcinoma), along with thyroid cancer. We focus on understanding how CXCL1 is involved in the cancer processes of these specific types of tumors. We look at how CXCL1 affects cancer cells, including their proliferation, migration, EMT, and metastasis. We also explore how CXCL1 influences other cells connected to tumors, like promoting angiogenesis, recruiting neutrophils, and affecting immune cell functions. Additionally, we discuss the clinical aspects by exploring how CXCL1 levels relate to cancer staging, lymph node metastasis, patient outcomes, chemoresistance, and radioresistance.

Abstract
Kaposi's sarcoma (KS) is a rare angioproliferative tumor classified in four different clinical-epidemiological forms. The diagnosis is based on histopathological and immunohistochemical analyses. The treatment is heterogeneous and includes several local and systemic therapeutic strategies. Methods: This is a retrospective cohort study including 86 KS patients treated between 1993 and 2022 at the University Hospital of Padua (AOPD) and at the Veneto Institute of Oncology (IOV). The data were extracted from an electronic database. Survival curves were generated using the Kaplan-Meier method, and Cox regression models were employed to explore associations with overall and disease-free survival. The male sex (89.53%), classical variant (43.02%), and cutaneous involvement (77.9%) were predominant. More than 61.6% of patients received a single treatment. Surgery, antiretroviral therapy, and chemotherapy were the mostly adopted approaches. A persistent response was observed in approximately 65% of patients, with a 22% relapse rate (at least 2 years). The overall survival ranges from 90 to 70% at 2 to 10 years after the diagnosis. Iatrogenic KS demonstrated a higher mortality (52.9%). This study reflects our experience in the management of KS. Comorbidities are very frequent, and treatments are heterogeneous. A multidisciplinary approach involving multiple referral specialists is essential for the appropriate management of this disease during diagnosis, treatment, and follow-up.

Abstract
We aimed to summarize the cancer risk among patients with indication of group I pharmaceuticals as stated in monographs presented by the International Agency for Research on Cancer working groups. Following the PRISMA guidelines, a comprehensive literature search was conducted using the PubMed database. Pharmaceuticals with few studies on cancer risk were identified in systematic reviews; those with two or more studies were subjected to meta-analysis. For the meta-analysis, a random-effects model was used to calculate the summary relative risks (SRRs) and 95% confidence intervals (95% CIs). Heterogeneity across studies was presented using the Higgins I square value from Cochran's Q test. Among the 12 group I pharmaceuticals selected, three involved a single study [etoposide, thiotepa, and mustargen + oncovin + procarbazine + prednisone (MOPP)], seven had two or more studies [busulfan, cyclosporine, azathioprine, cyclophosphamide, methoxsalen + ultraviolet (UV) radiation therapy, melphalan, and chlorambucil], and two did not have any studies [etoposide + bleomycin + cisplatin and treosulfan]. Cyclosporine and azathioprine reported increased skin cancer risk (SRR = 1.32, 95% CI 1.07-1.62; SRR = 1.56, 95% CI 1.25-1.93) compared to non-use. Cyclophosphamide increased bladder and hematologic cancer risk (SRR = 2.87, 95% CI 1.32-6.23; SRR = 2.43, 95% CI 1.65-3.58). Busulfan increased hematologic cancer risk (SRR = 6.71, 95% CI 2.49-18.08); melphalan was associated with hematologic cancer (SRR = 4.43, 95% CI 1.30-15.15). In the systematic review, methoxsalen + UV and MOPP were associated with an increased risk of skin and lung cancer, respectively. Our results can enhance persistent surveillance of group I pharmaceutical use, establish novel clinical strategies for patients with indications, and provide evidence for re-categorizing current group I pharmaceuticals into other groups.

Abstract
Kaposi's sarcoma (KS) is a malignancy that commonly appears as lesions on the skin or mucosal surfaces but can also develop in other organs. This cancer is usually caused by the human herpesvirus 8 (HHV-8), recently known as Kaposi's sarcoma-associated herpesvirus (KSHV). KS is rare in the general population but can develop in kidney transplant recipients with varying incidence due to immunocompromised status from immunosuppression. The main aim of the present systematic review was to identify the prevalence and treatment of KS in kidney transplant patients. PubMed, Cochrane Library, and Google Scholar databases were searched for studies until October 2023. Full-text studies with similar research objectives were included, while non-English articles, reviews, case reports, ongoing clinical trials, and studies evaluating KS in HIV patients or after other solid organ transplants were excluded. All studies were observational; therefore, methodological quality was assessed using the Newcastle-Ottawa Scale. The statistical analyses were performed with the Comprehensive Meta-Analysis (CMA) software (Biostat, Inc. Englewood, NJ). The pooled analysis from the 15 studies included showed that KS develops in 1.5% of kidney transplant recipients and is more prevalent in African (1.7%) and Middle Eastern (1.7%) recipients than in Western recipients (0.07%). KS was also significantly more prevalent among male recipients than female recipients (OR: 2.36; p < 0.0001). Additionally, cyclosporine-based immunosuppression accounts for most KS incidences (79.6%) compared to azathioprine-based immunosuppression (28.2%). Furthermore, reduction or withdrawal of immunosuppression alone resulted in 47.8% KS complete remissions. Post-kidney transplantation KS is more frequent among males and patients of Middle Eastern and African origin. However, the gender difference may be attributed to most patients undergoing kidney transplants being male. Therefore, if gender balance is considered in future studies, then the difference might be insignificant. Based on our results, we can concur that the mainstay treatment for post-transplant KS is reduction or withdrawal of immunosuppression. However, the patients should be closely monitored to avoid KS recurrence and kidney rejection. Furthermore, there is an increased risk for KS with the use of cyclosporine-based immunosuppression. However, this does not mean that the withdrawal of this immunosuppression agent might result in improved KS outcomes because the withdrawal of azathioprine with or without cyclosporine reduction has also led to improved outcomes.

Abstract
Modern immunosuppression has led to a decrease in rejection rates and improved survival rates after solid organ transplantation. Increasing the potency of immunosuppression promotes post-transplant viral infections and associated cancers by impairing immune response against viruses and cancer immunoediting. This review reflects the magnitude, etiology and immunological characteristics of various virus-related post-transplant malignancies, emphasizing the need for future research. A multidisciplinary and strategic approach may serve best but overall literature evidence targeting it is sparse. However, the authors attempted to provide a more detailed update of the literature consensus for the prevention, diagnosis, management and surveillance of post-transplant viral infections and associated malignancies, with a focus on the current role of adoptive immunotherapy and the way forward. In order to achieve long-term patient and graft survival as well as superior post-transplant outcomes, collaborative research on holistic care of organ recipients is imperative.

[PMID: 37734800 DOI: 10.1016/s2214-109x(23)00349-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Revised: 06/29/2023] [Accepted: 07/13/2023] [Indexed: 09/23/2023]
Abstract
BACKGROUND Kaposi sarcoma is a rare, possibly angioproliferative, tumour. Kaposi sarcoma is one of the most common cancers in people living with HIV and poses a serious public health challenge in regions with high HIV burden. We aim to describe global patterns and population-wide trends in the burden of Kaposi sarcoma. METHODS In this population-based study, the incidence and mortality estimates of Kaposi sarcoma from 185 countries and regions in 2020 were extracted from the GLOBOCAN 2020 database. The time trends in Kaposi sarcoma incidence were evaluated using the cancer registry data from Cancer Incidence in Five Continents plus from 1998 to 2012. We did not apply any inclusion or exclusion criteria to the data used in this study. Joinpoint regression was used to evaluate the average annual percentage change (AAPC) to quantify trends in the age-standardised incidence rate (ASIR) of Kaposi sarcoma. Correlation analysis was used to evaluate the relationship between the ASIR or age-standardised mortality rate (ASMR) and Human Development Index (HDI). FINDINGS In 2020, the global estimated ASIR of Kaposi sarcoma was 0·39 (per 100 000 people), with an estimated 34 270 newly diagnosed cases (23 413 males and 10 857 females). An estimated 15 086 Kaposi sarcoma deaths were reported (9929 males and 5157 females), corresponding to an ASMR of 0·18 (per 100 000 people). In 2020, Africa accounted for 73·0% (25 010 of 34 270) of the incidence and 86·6% (13 066 of 15 086) of the deaths from Kaposi sarcoma worldwide. There was a significant correlation between the ASIR or ASMR and HDI. The incidence of Kaposi sarcoma increased in males in both Türkiye and the Netherlands. The AAPC was 11·5% (95% CI 3·2-20·4) for males in Türkiye and 2·5% (1·1-3·9) for males in the Netherlands from 1998 to 2012. The incidence of Kaposi sarcoma decreased in White Americans, Israel, Uganda, Costa Rica, Colombia, Canada, and Denmark, from 1998 to 2012. INTERPRETATION Kaposi sarcoma is a relatively rare cancer worldwide but is endemic in some countries in southern and eastern Africa. Addressing disparities in health-care resource allocation and improving HIV/AIDS care across different HDI regions might contribute to the prevention of Kaposi sarcoma.

Abstract
Cutaneous vascular tumors constitute a heterogeneous group of entities that share overlapping morphologic and immunohistochemical features, which can be diagnostically challenging for pathologists and dermatopathologists. Our understanding and knowledge of vascular neoplasms have improved over time, resulting in both a refinement of their classification by the International Society for the Study of Vascular Anomalies (ISSVA) and an improvement in the accurate diagnosis and clinical management of vascular neoplasms. This review article aims to summarize the updated clinical, histopathological, and immunohistochemical characteristics of cutaneous vascular tumors, as well as to highlight their associated genetic mutations. Such entities include infantile hemangioma, congenital hemangioma, tufted angioma, spindle cell hemangioma, epithelioid hemangioma, pyogenic granuloma, Kaposiform hemangioendothelioma, retiform hemangioendothelioma, pseudomyogenic hemangioendothelioma, Kaposi sarcoma, angiosarcoma, and epithelioid hemangioendothelioma.

J Invest Dermatol 2023; 143:588-595.e3. [PMID: 36216206 PMCID: PMC10038815 DOI: 10.1016/j.jid.2022.09.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 09/02/2022] [Accepted: 09/13/2022] [Indexed: 11/06/2022]
Abstract
Antiretroviral therapy may alter susceptibility to nonkeratinocyte skin cancers (NKSCs) by improving immunity in people living with HIV. Using linked data from HIV and cancer registries in 12 states/regions in the United States during the antiretroviral therapy era (1996‒2018), we calculated standardized incidence ratios for 27 NKSCs, comparing incidence with that of the general population. Risk factors for NKSCs were evaluated using Poisson regression. There were 2,743 NKSCs diagnosed in 585,706 people living with HIV followed for 4,575,794 person-years. Kaposi sarcoma was the most common cancer (82%), followed by melanoma (12%) and cutaneous lymphoma (2.6%). Incidence was elevated for virus-related NKSCs: Kaposi sarcoma (standardized incidence ratio = 147, 95% confidence interval = 141‒153), diffuse large B-cell lymphoma (standardized incidence ratio = 5.19, 95% confidence interval = 3.13‒8.11), and Merkel cell carcinoma (standardized incidence ratio = 3.15, 95% confidence interval = 1.93‒4.87); elevated incidence for diffuse large B-cell lymphoma and Merkel cell carcinoma was observed only among people living with HIV with a previously acquired immunodeficiency syndrome diagnosis. Kaposi sarcoma risk was highest among men who have sex with men. Incidence was not increased for melanoma, adnexal carcinomas, and sarcomas. Melanoma and Merkel cell carcinoma arose disproportionately on sun-exposed skin, supporting a role for UVR in their development. In conclusion, risk for most NKSCs was similar to that of the general population during the antiretroviral therapy era, suggesting that people living with HIV without NKSC risk factors may not require intensive skin surveillance.

Variation in Post-Transplant Cancer Incidence among Italian Kidney Transplant Recipients over a 25-Year Period. Cancers (Basel) 2023; 15:cancers15041347.

Abstract
This cohort study examined 25-year variations in cancer incidence among 11,418 Italian recipients of kidney transplantation (KT) from 17 Italian centers. Cancer incidence was examined over three periods (1997-2004; 2005-2012; and 2013-2021) by internal (Incidence rate ratio-IRR) and external (standardized incidence ratios-SIR) comparisons. Poisson regression was used to assess trends. Overall, 1646 post-transplant cancers were diagnosed, with incidence rates/1000 person-years ranging from 15.5 in 1997-2004 to 21.0 in 2013-2021. Adjusted IRRs showed a significant reduction in incidence rates across periods for all cancers combined after exclusion of nonmelanoma skin cancers (IRR = 0.90, 95% confidence interval-CI: 0.76-1.07 in 2005-2012; IRR = 0.72, 95% CI: 0.60-0.87 in 2013-2021 vs. 1997-2004; Ptrend < 0.01). In site-specific analyses, however, significant changes in incidence rates were observed only for Kaposi's sarcoma (KS; IRR = 0.37, 95% CI: 0.24-0.57 in 2005-2012; IRR = 0.09, 95% CI: 0.04-0.18 in 2013-2021; Ptrend < 0.01). As compared to the general population, the overall post-transplant cancer risk in KT recipients was elevated, with a decreasing magnitude over time (SIR = 2.54, 95% CI: 2.26-2.85 in 1997-2004; SIR = 1.99, 95% CI: 1.83-2.16 in 2013-2021; Ptrend < 0.01). A decline in SIRs was observed specifically for non-Hodgkin lymphoma and KS, though only the KS trend retained statistical significance after adjustment. In conclusion, apart from KS, no changes in the incidence of other cancers over time were observed among Italian KT recipients.

Abstract
One of the main causes of post-transplant-associated morbidity and mortality is cancer. The aims of the project were to study the neoplastic risk within the kidney transplant population and identify the determinants of this risk. A cohort of 462 renal transplant patients from 2010 to 2020 was considered. The expected incidence rates of post-transplant cancer development in the referenced population, the standardized incidence ratios (SIR) taking the Italian population as a comparison, and the absolute risk and the attributable fraction were extrapolated from these cohorts of patients. Kidney transplant recipients had an overall cancer risk of approximately three times that of the local population (SIR 2.8). A significantly increased number of cases were observed for Kaposi's sarcoma (KS) (SIR 195) and hematological cancers (SIR 6.8). In the first 3 years post-transplant, the risk to develop either KS or hematological cancers was four times higher than in the following years; in all cases of KS, the diagnosis was within 2 years from the transplant. Post-transplant immunosuppression represents the cause of 99% of cases of KS and 85% of cases of lymphomas, while only 39% is represented by solid tumors. Data related to the incidence, the percentages attributable to post-transplant immunosuppression, and the time of onset of neoplasms, particularly for KS and hematological tumors could help improve the management for the follow-up in these patients.

Abstract
Kaposi sarcoma is relatively common after solid organ transplantation, but very rare after hematopoietic stem cell transplant (HSCT). Here we are reporting a rare case of Kaposi sarcoma in a child after HSCT. An 11-year-old boy with Fanconi anemia was treated by haploidentical HSCT from his father. Three weeks after transplantation, the patient developed severe graft-versus-host disease (GVHD) which was treated by immunosuppressive therapy and extracorporeal photopheresis. Approximately 6.5 months after HSCT, the patient had asymptomatic nodular skin lesions over the scalp, chest, and face. Histopathological examination showed typical findings of Kaposi sarcoma. Later, additional lesions in the liver and oral cavity were confirmed. Liver biopsy was positive for HHV-8 antibodies. The patient was continued on Sirolimus which was already being used for the treatment of GVHD. Cutaneous lesions were also treated with topical timolol 0.5% ophthalmic solution. Within six months, cutaneous and mucous membrane lesions were completely resolved. Follow-up abdominal ultrasound and MRI showed the disappearance of the hepatic lesion.

Abstract
Posttransplant malignancies, particularly recurrent and de novo, in solid organs including kidney transplant recipients (KTRs) are a significant complication associated with substantial mortality, largely attributed to long-term immunosuppression necessary to maintain allograft tolerance. Older age at transplantation and oncogenic virus infection along with pretransplant malignancies are among the main factors contributing to the risk of cancer in this population. As the mean age of transplant candidates rises, the rate of transplant recipients with pretransplant malignancies also increases. The eligibility criteria for transplantation in patients with prior cancer have recently changed. The overall risk of posttransplant malignancies is at least double after transplantation including KTRs relative to the general population, most pronounced for skin cancers associated with UV radiation and virally-mediated tumors. The risk of renal cell carcinoma is specifically increased in the kidney transplant population. The therapy of cancer in transplant patients is associated with risk of higher toxicity, and graft rejection and/or impairment, which poses a unique challenge in the management. Reduction of immunosuppression and the use of mTOR inhibitors are common after cancer diagnosis, although optimal immunosuppression for transplant recipients with cancer remains undefined. Suboptimal cancer treatment contributing to a worse prognosis has been reported for malignancies in this population. In this article, we focus on the prevalence and outcomes of posttransplant malignancies, cancer therapy including a short overview of immunotherapy, cancer screening and prevention strategies, and immunosuppression as a cancer risk factor. The 2020/2021 recommendations of the Kidney Diseases Improving Global Outcome (KDIGO) and American Society of Transplantation (AST) for transplant candidates with a history of cancer are presented.

Abstract
Kaposi's sarcoma is an angioproliferative tumor caused by human herpesvirus 8 in the context of immunodeficiency, such as that induced by HIV infection or immunosuppressive therapy. Its incidence has dramatically fallen in patients living with HIV (PLHIV) since the introduction of potent antiretroviral combinations 25 years ago due to the restoration of immunity and better control of HIV replication. However, KS is still one of the most frequently occurring cancers in PLHIV, in particular in men who have sex with men and in sub-Saharan Africa, where it is still endemic. Even in the context of restored immunity, the risk of KS is still more than 30 times higher in PLHIV than in the general population. Recent evidence indicates that early initiation of antiretroviral treatment, which is recommended by current guidelines, may reduce the risk of KS but it needs to be accompanied by early access to care. This review mainly focuses on the recent epidemiological features of KS in the context of HIV infection.

It is well known that solid-organ transplant recipients (SOTRs) have a 65- to 100-fold increase in the risk of developing skin cancer, namely, nonmelanoma skin cancers (NMSCs) such as cutaneous squamous cell carcinoma (cSCC) and basal cell carcinoma (BCC). In addition, these patients are also at increased risk for development of melanoma as well as other less common cutaneous malignancies (Merkel's cell carcinoma, Kaposi's sarcoma). SOTRs with NMSC (namely cSCC) are also at significantly increased risk of poor clinical outcomes including local recurrence, nodal and distant metastasis, and disease-specific death relative to patients who are not immunosuppressed. Increased surveillance and monitoring in patients at risk of aggressive disease and poor outcomes who are on immunosuppression is essential in patients with lung transplants given the high degree of immunosuppression. Increased awareness of risks, treatments, and management allows for improved outcomes in these patients. This article will provide an overview of the risk factors for the development of cutaneous malignancies in organ transplant recipients as well as a detailed discussion of various immunosuppressant and prophylactic medications used in this patient population that contribute to the risk of developing cutaneous malignancies, with an emphasis on NMSC (cSCC and BCC) in lung transplant recipients. Finally, this article includes a discussion on the clinical and dermatologic management of this high-risk immunosuppressed population including a review of topical and systemic agents for field therapy of actinic damage and chemoprevention of keratinocyte carcinomas. In addition, indications for additional treatment and preventive measures such as adjuvant radiation treatment after surgical management of cutaneous malignancies and potential modification of immunosuppressive medication regimens are discussed.

Abstract
Kaposi sarcoma (KS) following kidney transplantation can result from recipient reactivation of latent human herpesvirus 8 (HHV-8) infection or activation of donor-acquired HHV-8 infection. Post-transplant KS typically manifests with cutaneous pathology, but rare cases of renal allograft involvement have been reported. We describe two cases of donor-derived HHV-8 infection in two hepatitis C (HCV) viremia-negative transplant recipients who each received a kidney from a donor with HCV viremia. One recipient did not develop KS while the other presented with acute kidney injury caused by extensive KS infiltration of the renal parenchyma and metastatic disease. This report reviews the literature for cases of KS involving the renal allograft and highlights an unexpected consequence of deliberate HCV-positive organ transplantation.

Abstract
Human herpesvirus-8 (HHV-8) infection is associated with neoplastic and non-neoplastic diseases in immunocompromised patients. Kaposi sarcoma (KS) is a common malignancy reported in solid organ transplant recipients (SOTR). Kaposi sarcoma inflammatory cytokine syndrome (KICS), initially described in HIV patients, is characterized by high viral loads, elevated levels of cytokines, cytopenia, high fever, organ failure, and poor outcome. We report the case of a 54-year-old patient who developed simultaneous occurrence of KS of lymph nodes and KICS as a complication of primary donor-transmitted HHV-8 infection, after heart transplantation (HT). The diagnosis, management, and prognosis of this condition are unclear and needs a multidisciplinary approach.

Abstract
Question What is the association between voriconazole, an antifungal used to treat aspergillosis infections, and the risk of keratinocyte carcinomas among recipients of lung transplants? Findings In a population-based cohort study of 9599 non-Hispanic white recipients of 9793 lung transplants in the United States (2007-2016) with linkage to pharmacy claims, increasing cumulative voriconazole exposure was associated with an increased risk of cutaneous squamous cell carcinoma. Meaning These findings suggest that physicians caring for lung transplant recipients at high risk for aggressive keratinocyte carcinomas should limit voriconazole exposure when possible and encourage skin protection behaviors and more frequent cancer screenings. Importance The antifungal medication voriconazole is used to prevent and treat aspergillosis, a major cause of mortality among recipients of lung transplants (hereinafter referred to as lung recipients). Small studies suggest that voriconazole increases risk of cutaneous squamous cell carcinoma (SCC). Objective To examine associations of voriconazole and other antifungal medications with risk of keratinocyte carcinomas (SCC and cutaneous basal cell carcinoma [BCC]) in lung recipients. Design, Setting, and Participants This population-based cohort study included non-Hispanic white patients (n = 9599) who underwent lung transplant in the United States from January 1, 2007, to December 31, 2016, identified through the national Scientific Registry of Transplant Recipients with data linkable to pharmacy claims. Data were analyzed from March 1, 2018, to February 13, 2019. Exposures Antifungal medication use, including voriconazole, itraconazole, posaconazole, and other antifungals, was ascertained from pharmacy claims and treated as a time-varying exposure (assessed every 30 days). Cumulative antifungal exposure was calculated as the total number of exposed months. Main Outcomes and Measures Primary outcomes were the first SCC or BCC reported to the transplant registry by transplant centers. Follow-up began at transplant and ended at SCC or BCC diagnosis, transplant failure or retransplant, death, loss to follow-up, or December 31, 2016. Cox proportional hazards regression models were used to estimate adjusted hazard ratios (AHRs) for each antifungal medication. Results Among the 9793 lung transplants in 9599 recipients included in the analysis, median age at transplant was 59 (interquartile range [IQR], 48-65) years, 5824 (59.5%) were male, and 5721 (58.4%) reported ever smoking. During a median follow-up of 3.0 (IQR, 1.4-5.0) years after transplant, 1031 SCCs (incidence, 322 per 10 000 person-years) and 347 BCCs (incidence, 101 per 10 000 person-years) were reported. Compared with lung recipients with no observed voriconazole use, those with 1 to 3 months of voriconazole use experienced increased AHR for SCC of 1.09 (95% CI, 0.90-1.31); 4 to 7 months, 1.42 (95% CI, 1.16-1.73); 8 to 15 months, 2.04 (95% CI, 1.67-2.50); and more than 15 months, 3.05 (95% CI, 2.37-3.91). Ever itraconazole exposure was associated with increased SCC risk (AHR, 1.20; 95% CI, 1.00-1.45). For BCC, risk was not associated with voriconazole use but was increased with itraconazole use (AHR, 1.74; 95% CI, 1.27-2.37) or posaconazole use (AHR, 1.55; 95% CI, 1.00-2.41). Conclusions and Relevance In this study, voriconazole use was associated with increased SCC risk among lung recipients, especially after prolonged exposure. Further research evaluating the risk-benefit ratio of shorter courses or alternative medications in transplant recipients at high risk for SCC should be considered.

Abstract
Kaposi sarcoma (KS) can develop following organ transplantation through reactivation of recipient human herpesvirus 8 (HHV-8) infection or through donor-derived HHV-8 transmission. We describe 6 cases of donor-derived HHV-8 infection and KS investigated from July 2018 to January 2020. Organs from 6 donors, retrospectively identified as HHV-8-positive, with a history of drug use disorder, were transplanted into 22 recipients. Four of 6 donors had risk factors for HHV-8 infection reported in donor history questionnaires. Fourteen of 22 organ recipients (64%) had evidence of posttransplant HHV-8 infection. Lung recipients were particularly susceptible to KS. Four of the 6 recipients who developed KS died from KS or associated complications. The US opioid crisis has resulted in an increasing number and proportion of organ donors with substance use disorder, and particularly injection drug use history, which may increase the risk of HHV-8 transmission to recipients. Better awareness of the risk of posttransplant KS for recipients of organs from donors with HHV-8 infection risk could be useful for recipient management. Testing donors and recipients for HHV-8 is currently challenging with no validated commercial serology kits available. Limited HHV-8 antibody testing is available through some US reference laboratories and the Centers for Disease Control and Prevention.

Abstract
Introduction: Lung transplant recipients are at the highest risk of infectious complications among all solid-organ transplant (SOT) recipients. In the current era, many standardized protocols in terms of diagnostic algorithms, prophylaxis, and therapeutic strategies have improved the management of the most common infectious complications. Conversely, diagnosis of rare infections can be particularly challenging and this can delay appropriate treatment.Areas covered: This article will review the epidemiology, clinical presentation, diagnostic and therapeutic management of certain rarely reported viral, fungal, bacterial and parasitic infections in lung transplant recipients.Expert opinion: Once the most frequent infections are excluded, clinical suspicion combined with molecular diagnostic methods such as targeted and broad-spectrum PCRs can allow diagnosis of a rare infection. A multidisciplinary team, including transplant pulmonologists, transplant infectious diseases specialists, microbiologists and pathologists is essential for prompt diagnosis and optimal therapeutic management.

Abstract
Kaposi sarcoma (KS) is a vascular neoplasm caused by human herpesvirus-8 (HHV-8) infection. KS is most often seen in individuals with acquired immunodeficiency syndrome but can occur in patients who are on immunosuppressive therapy. While the skin and oral mucosa are the typical sites for KS, lesions of the tonsil are quite rare with only a few reported cases. Here, we present a case of tonsillar KS occurring in a renal transplant patient. He presented with dysphagia, odynophagia, and weight loss. Oral examination revealed tonsillar hypertrophy with purple discoloration. Imaging revealed diffuse enlargement of Waldeyer's ring with enlarged right cervical lymph nodes, worrisome for post-transplant lymphoproliferative disorder. Microscopic examination of the tonsillectomy specimen showed a vascular proliferation positive for HHV-8, consistent with KS. The patient was subsequently treated with immunosuppression reduction and the addition of sirolimus, which resulted in complete resolution of oropharyngeal and cervical lesions.

Abstract
PURPOSE OF REVIEW This review is a brief overview of current guidelines on screening donors and candidates for bacterial, fungal, parasitic and viral infections prior to solid organ transplantation. The pretransplant period is an important time to evaluate infection exposure risk based on social history as well as to offer vaccinations. RECENT FINDINGS One of the major changes in the past few years has been increased utilization of increased Public Health Service risk, HIV positive, and hepatitis C-positive donors. There has also been increased attention to donor and recipient risks for geographically associated infections, such as endemic fungal infections and flaviviruses. SUMMARY Screening for donors and candidates prior to organ transplantation can identify and address infection risks. Diagnosing infections in a timely manner can help guide treatment and additional testing. Use of necessary prophylactic treatment in organ recipients can prevent reactivation of latent infections and improve posttransplant outcomes.

Abstract
Skin cancers are among the rarely seen complications after solid-organ transplant. Kaposi sarcoma invasion to an allograft is an uncommon condition. In this study, we present a case of Kaposi sarcoma in a 58-year-old patient diagnosed at 8 months after bilateral sequential lung transplant due to chronic obstructive pulmonary disease. Kaposi sarcoma showed rapid progression despite immunosuppressive drug modification, resulting in lung involvement and respiratory failure. Rapid and complete improvement was achieved with rapid diagnosis and aggressive treatment that included combined chemotherapy after surgery. The patient presented with no complications from Kaposi sarcoma at month 26 after transplant.

Abstract
Kaposi sarcoma (KS) is the most common tumor in patients with human immunodeficiency virus (HIV), and its frequency is increasing after organ transplantation in HIV-negative patients. A 28-year-old woman had preemptive kidney transplantation from her 48-year-old mother. In the postoperative ninth month, an exophytic mass was found in the upper medial conjunctiva of the right eye. The lesion was excised under local anesthesia, and cryotherapy was applied to the surgical area. The biopsy result was reported as KS. Treatment with tacrolimus was switched to everolimus (EVO), but EVO was discontinued because of pneumonitis. The patient was followed without any recurrences after the excision of the conjunctival lesion. No local or systemic recurrence was observed in the 14th month after surgical excision and local cryotherapy. Local treatment and the reduction of immunosuppressive therapy may be effective in the treatment of conjunctival KS.

Abstract
Kaposi Sarcoma (KS) is driven by human herpes virus 8 causing vascular proliferation which is induced by loss of immune function most often due to HIV or immunosuppressants. KS occurs with increased incidence in kidney transplant recipients, but rarely is disseminated. We report a 64-year-old male who developed severely disseminated KS 5 months after ABO-incompatible kidney-transplantation. No guidelines for chemotherapy exist in this case and reduced kidney function and impaired immune system complicates the use of systemic chemotherapy in kidney transplant recipients. A combination of paclitaxel and gemcitabine followed by two days of hemodialysis treatment was chosen since paclitaxel can be given in full dose independently of kidney function and gemcitabine is metabolised to 2′,2′-difluorodeoxyuridine which is found to be highly dialysable. The present treatment was well tolerated by the patient with one episode of leukopenia and elevated alanine transaminase during treatment which resolved. There were no serious adverse events and the patient obtained a complete remission verified by Positron Emission Tomography CT after ending chemotherapy and at one-year follow up.

Abstract
The advent in the last several years of effective immunotherapy for cancer has renewed interest in the role of the immune system in controlling cancer. The idea that the immune system can help control cancer has a long history. Solid organ transplant recipients (SOTRs) as well as human immunodeficiency virus (HIV)-infected people are affected by cell-mediated immune dysfunction. Epidemiologic studies of these populations reveal a pattern characterized by a strongly increased incidence of virus-related cancers (eg, Kaposi sarcoma, non-Hodgkin lymphoma, and anogenital cancers). In addition, recent epidemiologic studies have evaluated cancer-specific mortality among SOTRs and HIV-infected people following a cancer diagnosis. For a wider range of cancers-not limited to those caused by viruses, and including melanoma and cancers of the colorectum, lung, and breast- these immunosuppressed cancer patients have higher cancer-specific mortality than other cancer patients. This latter group of cancers somewhat mirrors those for which immunotherapy with checkpoint inhibitors is approved. These epidemiologic observations suggest that there are 2 distinct immune selection processes in humans: immunosurveillance directed against premalignant cells before cancer diagnosis (most relevant for preventing virus-related cancers), and "immunocontainment" directed against established cancers. These processes thus appear relevant for different groups of malignancies and may have different mechanisms.

Abstract
Kaposi sarcoma (KS) is an angioproliferative mesenchymal neoplasm caused by Kaposi sarcoma-related herpesvirus. This review outlines our current understanding of the epidemiology, pathogenesis, clinical presentation, and staging for this disease. Recent research has informed a more comprehensive understanding of the epidemiology of KS in the post-antiretroviral therapy era, and highlights the continued need to better characterize the African endemic subtype. Advances in clinical oncology, including checkpoint inhibitors and new skin-directed therapies, have translated into exciting new developments for the future of KS treatment options.

Abstract
In areas of the world where human herpesvirus 8 (HHV-8) is endemic, Kaposi sarcoma (KS) is a common SOT-associated cancer. In the United States, where the virus is not prevalent, PTKS is rare, and there is little literature on pediatric PTKS. We present a North American female who underwent deceased donor, left lateral segment liver transplant for biliary atresia at age 11 months. The donor was a male with no known history of KS, originally from an HHV-8-endemic country. Three months after transplantation, the patient developed liver nodules and portal vein thrombosis. Analysis of needle biopsy established the diagnosis of KS and confirmed that the transformed cells were donor-derived. HHV-8 viremia was detected, and ganciclovir dosing (which had been started prophylactically) was increased. Immunosuppression was changed from tacrolimus to sirolimus. After further disease progression, 8 cycles of paclitaxel were administered. Under this treatment, her nodules regressed, HHV-8 viremia resolved, and she had marked clinic improvement. Notably, the adult recipient of the right liver lobe from the same donor also developed PTKS. This is one of few pediatric PTKS cases described in the literature. It contributes to the mechanistic understanding of PTKS development, illustrating the risk posed by donors from HHV-8-endemic countries, as well as the potential for strong PTKS correlation between multiple recipients of organs from a single shared donor.

Abstract
These updated guidelines from the Infectious Diseases Community of Practice of the American Society of Transplantation review the diagnosis, prevention, and management of HHV-6A, HHV-6B, HHV-7, and HHV-8 in the pre- and post-transplant period. The majority of HHV-6 (A and B) and HHV-7 infections in transplant recipients are asymptomatic; symptomatic disease is reported infrequently across organs. Routine screening for HHV-6 and 7 DNAemia is not recommended in asymptomatic patients, nor is prophylaxis or preemptive therapy. Detection of viral nucleic acid by quantitative PCR in blood or CSF is the preferred method for diagnosis of HHV-6 and HHV-7 infection. The possibility of chromosomally integrated HHV-6 DNA should be considered in individuals with persistently high viral loads. Antiviral therapy should be initiated for HHV-6 encephalitis and should be considered for other manifestations of disease. HHV-8 causes Kaposi's sarcoma, primary effusion lymphoma, and multicentric Castleman disease and is also associated with hemophagocytic syndrome and bone marrow failure. HHV-8 screening and monitoring may be indicated to prevent disease. Treatment of HHV-8 related disease centers on reduction of immunosuppression and conversion to sirolimus, while chemotherapy may be needed for unresponsive disease. The role of antiviral therapy for HHV-8 infection has not yet been defined.

Abstract
BACKGROUND: Kaposi’s sarcoma was first described in 1872 by Moritz Kaposi. To date, it is considered a malignant disease is originating from the endothelial cells of the lymphatic vessels believed to be infected with HHV-8. The current classification defines four major epidemiological forms of Kaposi’s sarcoma: classical, endemic, AIDS-associated, and iatrogenic. CASE REPORT: A 90-year-old male is presented with multiple plaques- and tumour-shaped brown-violet formations located on an erythematous-livid base in the area of both feet and both shanks. Two samples were taken from the lesions on the skin of the shanks, with histopathological examination and the subsequent immunohistochemistry showing Kaposi’s sarcoma. CONCLUSIONS: Kaposi sarcoma is a disease that causes difficulties both in diagnostic and therapeutic respect. The only sure way to determine the correct diagnosis is immunohistochemical staining with the anti-HHV8 antibody. Despite the wide range of systematic and local treatment options, there is still no unified algorithm and a unified strategy for the treatment of Kaposi’s sarcoma.
