Abstract
With the rising prevalence of organ transplantation, clinicians must be aware of the many potential complications that may arise. One such complication is post-transplantation melanoma. Herein, we present a case of advanced metastatic melanoma following orthotopic liver transplantation (OLT). This is a 54-year-old cirrhotic male who underwent OLT that was complicated by metastatic melanoma. Despite adherence to yearly screening guidelines and timely radiation and immunotherapy, the disease course was rapidly progressive and fatal. This case aims to highlight the risk of post-transplantation melanoma and the potential need for screening modifications to identify melanoma earlier in its development. The association between organ transplantation and melanoma is well-reported, but the underlying risks and mechanisms remain incompletely understood. One potential risk factor is post-transplant immunosuppressive therapy, which may result in fatally aggressive melanoma. Understanding the potential mortality risks in transplant patients, modifications to peri-transplant screening guidelines, and immunosuppressive therapy may be lifesaving.

Abstract
The European Society for Medical Oncology experts have identified the main components of the long-term management of oncological patients. These include early diagnosis through population screening and periodic control of already diagnosed patients to identify relapses, recurrences, and other associated neoplasms. There are no generally accepted international guidelines for the long-term monitoring of patients with skin neoplasms (nonmelanoma skin cancer, malignant melanoma, precancerous-high-risk skin lesions). Still, depending on the experience of the attending physician and based on the data from the literature, one can establish monitoring intervals to supervise these high-risk population groups, educate the patient and monitor the general population.

Abstract
OBJECTIVES Our main objective was to investigate donor-transmitted epithelial cancers of all origins in comparison with breast cancers, with analysis of the carcinological outcome of recipients. Our secondary objective was to define medical check-up to be performed before any organ procurement from a donor with a history of breast cancer. METHODOLOGY We performed a systematic review of the literature up to June 1st 2022 by including all original articles (including clinical cases) reporting cases of epithelial cancer transmitted from donor to recipient, followed by a meta-analysis of epidemiological and survival data. RESULTS In total, we included 52 articles (31 clinical cases and 21 cohort studies), representing 91,388 donors, 236,142 recipients, and 2591 cases of transmitted cancer. The risk of transmitted cancer was significantly higher with a history of breast cancer compared with a history of other cancer (RR=9.48 P=0.0025). In clinical cases, the pre-donation check-up was specified in only 33.3% of publications. The time between transplantation and cancer occurrence was longer in cases of breast cancer transmission compared to other epithelial cancers: 1435.8 days versus 297.6 (P<0.001). CONCLUSION Organ donation from a person previously treated for breast cancer or having a risk of occult breast cancer is possible in some situations but requires an adapted pre-donation assessment, the respect of good practice guidelines and an expert opinion in complex situations.

Metastatic Donor-derived Malignancies Following Simultaneous Pancreas-kidney Transplant: Three Case Reports and Management Strategies. Transplant Direct 2020; 7:e636.

Abstract
Stopping immunosuppression in a transplant patient with donor-derived malignancy offers the theoretical benefit that reconstitution of the patient's immune system will allow "rejection" of the malignancy, as the malignancy also originates from allogeneic tissue. However, this option exists with the caveat that the patient's allograft(s) will likely be rejected too. In simultaneous pancreas-kidney (SPK) recipients, the normal continued functioning and possible absence of malignancy in either the unaffected kidney or pancreas further complicate this decision. Methods The charts of 3 patients with donor-derived metastatic malignancies after SPK were retrospectively reviewed in detail. We provide treatment and management recommendations based on successful outcomes and a review of the existing literature. Results Consistent with a broad review of the literature, in all 3 cases, complete immunosuppression cessation, removal of both grafts, and in 1 case treatment with an immune checkpoint inhibitor to augment the immune response was successful. One patient is doing well 1 year after successfully undergoing kidney retransplantation, while a second patient is active on the waitlist for SPK retransplantation after no evidence of metastatic disease for 2 years. Conclusion The successful management of metastatic donor-derived malignancies requires allograft removal, immunosuppression cessation, and adjuvant therapy that includes occasional use of checkpoint inhibitors to augment the immune response.

Abstract
OPINION STATEMENT Global organ scarcity remains a severe obstacle because of the rapid growth in the number of patients on the transplant waiting list. Transplant centres strive to raise the number of donors by proposing more mild criteria for donor selection, among them donors with a history of malignancy and older age. Recipients are at hazard of acquiring tumour that existed in the donor at the time of transplantation with the most common cancers been renal cell carcinoma (57%), melanoma (10%), and choriocarcinoma (9%). Tumour origin can be established by PCR-based DNA analysis for microsatellite markers, HLA typing, immunohistochemistry, or fluorescent in situ hybridisation. The general recommendation for treatment of donor-related melanoma is a cessation of immunosuppression therapy to allow rejection of the allograft and its immediate removal. In non-renal transplant patients with life-sustaining organs or if allograft removal is denied, reduction of immunosuppression, chemoradiation therapy, and urgent retransplantation are the only potential strategies. Checkpoint inhibitors were reported to be effective in several cases of donor-transmitted melanoma and now emerge as an innovative option to standard chemotherapy and the potential for cure.

Can chimerism explain breast/ovarian cancers in BRCA non-carriers from BRCA-positive families? PLoS One 2018; 13:e0195497.

Abstract
Hereditary breast and ovarian cancer syndrome (HBOC) is most frequently caused by mutations in BRCA1 or BRCA2 (in short, BRCA) genes. The incidence of hereditary breast and ovarian cancer in relatives of BRCA mutation carriers who test negative for the familial mutation (non-carriers) may be increased. However, the data is controversial, and at this time, these individuals are recommended the same cancer surveillance as general population. One possible explanation for BRCA phenocopies (close relatives of BRCA carriers who have developed cancer consistent with HBOC but tested negative for a familial mutation) is natural chimerism where lack of detectable mutation in blood may not rule out the presence of the mutation in the other tissues. To test this hypothesis, archival tumor tissue from eleven BRCA phenocopies was investigated. DNA from the tumor tissue was analyzed using sequence-specific PCR, capillary electrophoresis, and pyrosequencing. The familial mutations were originally detected in the patients’ first-degree relatives by commercial testing. The same testing detected no mutations in the blood of the patients under study. The test methods targeted only the known familial mutation in the tumor tissue. Tumor diagnoses included breast, ovarian, endometrial and primary peritoneal carcinoma. None of the familial mutations were found in the tumor samples tested. These results do not support, but do not completely exclude, the possibility of chimerism in these patients. Further studies with comprehensive sequence analysis in a larger patient group are warranted as a chimeric state would further refine the predictive value of genetic testing to include BRCA phenocopies.

Abstract
The relatively high DNA mutational burden in melanoma allows for the creation of potentially "foreign," immune-stimulating neoantigens, and leads to its exceptional immunogenicity. Brisk tumor-infiltrating lymphocytes, a marker of immune editing, confer improved overall survival in melanoma, possibly due to reduced sentinel lymph node spread. Meanwhile, T-cell-stimulating drugs, so-called T-cell checkpoint inhibitors, which reverse peripheral tolerance-dependent tumor escape, have demonstrated unparalleled clinical success in metastatic melanoma. Markers to predict response to immunotherapy are currently imperfect, and the subject of intense research, which will guide the future of ancillary pathologic testing in this setting.

Abstract
In the ever-aging population of the world, the field of geriatrics continues to grow in importance. As human beings age, the skin undergoes a unique array of changes that predispose it to a specific set of dermatoses, infections, and neoplasms. Some of these physiologic alterations are comparable to the changes that happen in immunosuppressed individuals. Given the importance of immunosuppressive medications in treatment of many common skin conditions, we have reviewed the current literature to assist the practicing clinician in using immunosuppressive medications in the geriatric population.

Abstract
Tumor reductive therapy is to reduce tumor burden through direct killing of tumor cells. So far, there is no report on the connection between antitumor immunity and tumor reductive therapies. In the last few years, a new category of cancer treatment, immunotherapy, emerged and they are categorized separately from classic cytotoxic treatments (chemo and radiation therapy). The most prominent examples include cellular therapies (LAK and CAR-T) and immune checkpoint inhibitors (anti-PD-1 and CTLA-4). Recent advances in clinical immunotherapy and our understanding of the mechanism behind them revealed that these therapies have a closer relationship with classic cancer treatments than we thought. In many cases, the effectiveness of classic therapies is heavily influenced by the status of the underlying antitumor-immunity. On the other hand, immunotherapies have shown better outcome when combined with tumor reductive therapies, not only due to the combined effects of tumor killing by each therapy but also because of a synergy between the two. Many clinical observations can be explained once we start to look at these classic therapies from an immunity standpoint. We have seen their direct effect on tumor antigen in vivo that they impact antitumor immunity more than we have realized. In turn, antitumor immunity contributes to tumor control and destruction as well. This review will take the immunological view of the classic therapies and summarize historical as well as recent findings in animal and clinical studies to make the argument that most of the cancer treatments exert their ultimate efficacy through antitumor immunity.

Abstract
Characterizing the interaction of cancer cells with the host adaptive immune system is critical for understanding tumor immunology and the modus operandi of immunotherapeutic interventions to treat cancer. As the key cellular effectors of adaptive immunity, T cells are endowed with specialized receptors (the T cell receptor; TCR), to recognize and to eliminate cancer cells. The diversity of the TCR repertoire results from specialized genetic diversification mechanisms that generate an incredible variability allowing recognizing extensive collections of antigens. Based on the attainment and function of the TCR, the TCR repertoire is a mirror of the human immune response, and the dynamic changes of its usage can be assumed as a promising biomarker to monitor immunomodulatory therapies. Recent advances in multiplexed PCR amplification and massive parallel sequencing technologies have facilitated the characterization of TCR repertoires at high resolution even when only biomaterial of limited quantity and quality, such as formalin-fixed paraffin-embedded (FFPE) archived tissues, is available. Here, we review the concept framework and current experimental approaches to characterize the TCR repertoire usage in cancer including inherent technical and biological challenges.

Abstract
According to the European Union Tissues and Cells Directives donation of tissue is contraindicated in the presence of or a previous history of malignant disease, with the exception of cutaneous basal cell carcinoma. Skin cancer is the most common cancer. Due to ultraviolet light exposure and increasing life expectancy an increasing prevalence of malignant or premalignant skin lesions is observed, which may result in a decline of the availability of skin for transplantation. A risk assessment based on published studies and expert opinion was performed in order to investigate the risk of transmitting malignant or premalignant skin lesions through tissue transplantation, and more particular through skin transplantation. The scarcity of data concerning cancer transmission in tissue transplantation was challenging. Circumstantial evidence, available for organ transplantation, was used to develop the following policy proposal for skin transplantation and cutaneous tumours. Malignant melanoma is an absolute contraindication for the donation of skin and also of other tissues, whereas, non-lesional skin and other tissues of a donor with non-melanoma skin cancer (basal cell and squamous cell carcinoma) or with a premalignant skin lesion can be considered for transplantation. The above mentioned protocol proposal might serve as a prototype for analogous protocols for non-cutaneous malignancies.

Abstract
Cancers in solid organ recipients may be classified as donor transmitted, donor derived, de novo or recurrent. The risk of donor-transmitted cancer is very low and can be reduced by careful screening of the donor but cannot be abolished and, in the United Kingdom series is less than 0.03%. For donors with a known history of cancer, the risks will depend on the nature of the cancer, the interventions given and the interval between diagnosis and organ donation. The risks of cancer transmission must be balanced against the risks of death awaiting a new graft and strict adherence to current guidelines may result increased patient death. Organs from selected patients, even with high-grade central nervous system (CNS) malignancy and after a shunt, can, in some circumstances, be considered. Of potential donors with non-CNS cancers, whether organs may be safely used again depends on the nature of the cancer, the treatment and interval. Data are scarce about the most appropriate treatment when donor transmitted cancer is diagnosed: sometimes substitution of agents and reduction of the immunosuppressive load may be adequate and the impact of graft removal should be considered but not always indicated. Liver allograft recipients are at increased risk of some de novo cancers, especially those grafted for alcohol-related liver disease and hepatitis C virus infection. The risk of lymphoproliferative disease and cancers of the skin, upper airway and bowel are increased but not breast. Recipients should be advised to avoid risk behavior and monitored appropriately.

Abstract
Cancer is now the most severe complication in the long term in transplant recipients. As most solid-organ or hematopoietic stem-cell transplantations are allogeneic, chimerism studies can be performed on cancers occurring in recipients. We summarize here the different methods used to study chimerism in cancers developing in allogeneic-transplant recipients, analyze their respective advantages and report the main results obtained from these studies. Chimerism analyses of cancers in transplant recipients require methods suited to tissue samples. In the case of gender-mismatched transplantation, the XY chromosomes can be explored using fluorescent in situ hybridization on whole-tissue sections or Y-sequence-specific PCR after the laser microdissection of tumor cells. For cancers occurring after gender-matched transplantation, laser microdissection of tumor cells enables studies of microsatellite markers and high-resolution melting analysis of mitochondrial DNA on genes with marked polymorphism, provided these are different in the donor and the recipient. The results of different studies address the cancers that develop in both recipients and in transplants. The presence of chimeric cells in these two types of cancer implies an exchange of progenitor/stem-cells between transplant and recipient, and the plasticity of these progenitor/stem-cells contributes to epithelial cancers. The presence of chimeric cells in concomitant cancers and preneoplastic lesions implies that the oncogenesis of these cancers progresses through a multistep process.

Abstract
Neoplasms in children after organ transplantation are related to the type and intensity of immunosuppression and the donor-recipient serostatus, especially in relation to the Epstein-Barr virus. The patient was a two-yr-old female child with biliary atresia who underwent a liver transplantation from a female cadaver donor. Two adults received kidney transplants from the same donor. Nine months after transplantation, one of the adult recipients developed an urothelial tumor in the kidney graft. Imaging tests were repeated monthly in the liver-transplanted child and revealed no abnormalities. However, one yr and two months after the transplantation, the patient developed episodes of fever. At that time, imaging and liver biopsy showed a clear cell tumor of urothelial origin in the graft and the disease was limited to the liver. The patient underwent liver retransplantation, and she is currently free of tumor recurrence. Although rare, the occurrence of tumors in the post-transplant period from cadaver donors, without previously diagnosed tumors, is one of the many problems encountered in the complex world of organ transplantation.

Abstract
Several criteria are used to differentiate between standard and extended allograft donors. These criteria include deceased after cardiac death, advanced donor age, steatosis, previous malignancy in the donor, hepatitis C virus-positive allografts, human T-cell lymphotropic virus-positive allografts, active infections in the donor, high-risk donors, split liver transplantations, and living donor liver transplantations. Review of the literature can lead each practitioner to incorporate extended criteria donors into their transplant program, thereby individualizing the use of these allografts, increasing the donor pool, and decreasing overall waitlist mortality.

Abstract
Over the past several decades, there has been increasing interest in understanding the roles of the immune system in the development and progression of cancer. The importance of the immune system in human skin cancer has been long recognized based primarily upon the increased incidence of skin cancers in organ transplant recipients and mechanisms of ultraviolet (UV) radiation-mediated immunomodulation. In this review, we integrate multiple lines of evidence highlighting the roles of the immune system in skin cancer. First, we discuss the concepts of cancer immunosurveillance and immunoediting as they might relate to human skin cancers. We then describe the clinical and molecular mechanisms of skin cancer development and progression in the contexts of therapeutic immunosuppression in organ transplant recipients, viral oncogenesis, and UV radiation-induced immunomodulation with a primary focus on basal cell carcinoma and squamous cell carcinoma. The clinical evidence supporting expanding roles for immunotherapy is also described. Finally, we discuss recent research examining the functions of particular immune cell subsets in skin cancer and how they might contribute to both antitumour and protumour effects. A better understanding of the biological mechanisms of cancer immunosurveillance holds the promise of enabling better therapies.

Abstract
Abstract
Malignant diseases are considered as great challenges in clinical transplantation. It is well known that the incidence of malignancy is higher in the transplanted population if compared with the normal population. It is important to distinguish between neoplastic diseases originating from pre-existing lesions in the transplanted organs and de novo graft tumours. Post-transplant malignancy of donor origin is a rare complication of organ transplantation, most likely transmitted as micrometastases within the parenchyma of the donor organ or from circulating tumour cells contained within the organ. Malignant melanoma, although its incidence is rather low, is one of the most common donor-derived tumour inadvertently transplanted, comprising 28% of donor transmitted tumours. Malignant melanoma in the graft without dermatological localisation is extremely rare. We report a case of de novo melanoma occurring in the allograft, where transmission from the donor was excluded by DNA (desoxyribonucleic acid) investigation. We did not find any data in the literature where a malignant melanoma occurred after transplantation in the transplanted kidney without any skin lesions and the donor origin was excluded. We draw attention to the importance of the DNA typing in case of tumours occurring in immunosuppressed patients.
