Abstract
Posttransplant lymphoproliferative disorder is a group of heterogenous disorders that occur after solid-organ transplant. The overall incidence is between 1% and 20%. In orthotopic liver transplant recipients, the reported incidence ranges from 2% to 10%, while the incidence is greater in children (9.7%-11%) and lesser in adults (1.7%-3%). The following treatment options are considered for patients with posttransplant lymphoproliferative disorder: reduction of immunosuppression, single-agent rituximab, rituximab and chemotherapy, surgery and radiation, antivirals targeted at the Epstein-Barr virus, and cytotoxic T-lymphocytes targeting the Epstein-Barr virus. This report describes a 61-year-old man who presented after an orthotopic liver transplant with a large periportal soft tissue mass that was shown on biopsy to be a monomorphic, CD20+, diffuse, large B-cell lymphoma, nongerminal center type. He was treated with reduced immunosuppression, followed by single-agent rituximab, then with an anthracycline-based chemotherapy regimen: rituximab, etoposide, prednisone, vincristine, doxorubicin, and then a platinum-based salvage chemotherapy with rituximab, dexamethasone, cytarabine, and cisplatin with a good response.

Abstract
Post-transplant lymphoproliferative disease (PTLD) is the most frequent malignant complication of transplantation in childhood. Even with modern post-transplant immunosuppressive strategies, 1-2% of all kidney transplant recipients will develop PTLD within the first 5 years after transplantation, and the risk remains high even thereafter as long as immunosuppression is required. In addition to PTLD, adult kidney transplant recipients have an increased incidence of other immunosuppression-related malignancies, such as non-melanoma skin cancer or Kaposi's sarcoma. It is foreseeable that pediatric transplant recipients will face similar complications during their adult life. Not only immunosuppression but also other risk factors have been identified for some of these malignancies. Strategies addressing these risk factors during childhood may contribute to life-long cancer prevention. Furthermore, early recognition and regular screening may facilitate early diagnosis and treatment, thereby reducing transplant-related morbidity. In this review we focus on malignant complications after renal transplantation and discuss known risk factors. We also review current screening strategies for malignancies during post-transplant follow-up.

Abstract
Organ transplantation is an increasingly used medical procedure for treating otherwise fatal end-stage organ diseases, and a large number of anti-rejection drugs have been developed to prolong long-term survival of both the individual and the transplanted organ. However, the prolonged use of immunosuppressive drugs is well known to increase the risk of opportunistic diseases, particularly infections and virus-related malignancies. Although transplant recipients experience a nearly twofold elevated risk for all types of de novo cancers, persistent infections with oncogenic viruses are associated with up to hundredfold increased risks. Women of the reproductive age are growing in number among the recipients of solid-organ transplants, but specific data on cancer outcomes are lacking. This article updates evidences linking iatrogenic immunosuppression, persistent infections with oncogenic viruses, other risk factors and post-transplant malignancies. Epidemiological aspects, tumourigenesis related to oncogenic viruses, clinical implications, as well as primary and secondary prevention issues are discussed to offer clinicians and researchers alike an update of an increasingly important topic.

Abstract
Post-transplantation lymphoproliferative disorders (PTLD) are associated with poor patient and graft survival. The risk of rejection and subsequent graft loss are increased by the reduction of immunosuppression therapy, the cornerstone of PTLD treatment. This multicentre, retrospective, nonrandomized cohort study includes 104 adults who developed PTLD after renal or simultaneous renal/pancreatic transplantation between 1990 and 2007. It examines the effect of calcineurin inhibitor (CNI) withdrawal on long-term graft and patient survival. At 10 years postonset of PTLD, the Kaplan-Meier graft loss rate was 43.9% and graft loss or death with functioning graft was 64.4%. Cox multivariate analysis determined risk factors of graft loss as PTLD stage greater than I-II and CNI withdrawal, and for graft loss and mortality, these remained risk factors along with age over 60 years. Type and location of PTLD, year of diagnosis, and chemotherapy regime were not independent risk factors. Multivariate analysis determined CNI withdrawal as the most important risk factor for graft loss (HR = 3.07, CI 95%: 1.04-9.09; P = 0.04) and death (HR: 4.00, CI 95%: 1.77-9.04; P < 0.001). While long-term stable renal function after definitive CNI withdrawal for PTLD has been reported, this review determined that withdrawal is associated with reduced graft and patient survival.

Abstract
BACKGROUND Posttransplant lymphoproliferative disorder (PTLD) is a life-threatening complication of organ transplantation that results from immunosuppression therapy. Most cases of PTLD derive from the B-cell lineage. T-cell PTLD, particularly natural killer (NK)/T-cell PTLD, is quite rare; only a few cases have been described. CASE REPORT A 42-year-old woman received a living-related renal allograft from her father. Sixteen years after transplantation, the patient presented with a 1-week history of low-grade fever and epigastralgia. Computed tomography revealed intestinal masses and a right upper lung lobe mass. Gallium scintigraphy showed uptake in the abdominal mass. Epstein-Barr virus-related antibody was not detected in the patient's serum sample. We performed extirpation of the jejunum and ileum tumors. The pathologic findings showed that these 2 tumors were NK/T-cell lymphoma. After the operation, the lung mass rapidly enlarged, and right upper lobectomy was performed. The right upper lung lobe tumor showed the same histopathologic findings as the small bowel tumor. The final histologic diagnosis was established as multiple extranodal NK/T cell type PTLD of the small bowel and right upper lung lobe. CONCLUSIONS After reduction of the immunosuppressive agent, no recurrence of PTLD has been observed for the past 9 years.

Abstract
Epstein-Barr virus (EBV) DNAemia in the first year posttransplantation has been studied extensively. There is a paucity of information on prevalence and sequelae of EBV infection in adult renal transplantation beyond the first year. This single-center study examines the relationship between EBV DNAemia and demographic, immunosuppressive, hematologic and infection-related parameters in 499 renal transplant recipients between 1 month and 33 years posttransplant. Participants were tested repeatedly for EBV DNAemia detection over 12 months and clinical progress followed for 3 years. Prevalence of DNAemia at recruitment increased significantly with time from transplant. In multivariate adjusted analyses, variables associated with DNAemia included EBV seronegative status at transplant (p = 0.045), non-White ethnicity (p = 0.014) and previous posttransplant lymphoproliferative disease (PTLD) diagnosis (p = 0.006), while low DNAemia rates were associated with mycophenolate mofetil use (p < 0.0001) and EBV viral capsid antigen positive Epstein-Barr nuclear antigen-1 positive serostatus at transplant (p = 0.044). Patient and graft survival, rate of kidney function decline and patient reported symptoms were not significantly different between EBV DNAemia positive and negative groups. EBV DNAemia is common posttransplant and increases with time from transplantation, but EBV DNAemia detection in low-risk (seropositive) patients has poor specificity as a biomarker for future PTLD risk.

Abstract
BACKGROUND Epstein-Barr virus (EBV) plays a major role in the development of post-transplant lymphoproliferative disorder (PTLD), but there is an increasing awareness of EBV-negative PTLD. The clinical presentation of EBV-negative PTLD has not been as well characterised as EBV-positive cases. Further, there is limited knowledge on the clinical importance of diffuse large B-cell lymphoma (DLBCL) cell of origin subtype post-transplant. MATERIALS AND METHODS We studied the role of EBV, hepatitis C (HCV) and DLBCL subtype in clinical presentation and survival in 135 post-transplant lymphomas diagnosed 1980-2006 in a population-based cohort of 10 010 Swedish solid organ transplant recipients. The lymphomas were re-evaluated according to WHO 2008, examined for EBV, and clinical data were collected from medical records. RESULTS Lymphoma incidence rate was 159/100 000 person-years and is also reported by lymphoma subtype. EBV-negative lymphomas constituted 48% and were associated with HCV infection (p = 0.02), bone marrow involvement (p < 0.001), and T-cell phenotype (p = 0.002). Among DLBCL, 78% were of non-germinal centre subtype, which was associated with EBV-positivity (69%, p = 0.001), early occurrence (p = 0.03), heart/liver/lung/pancreas recipients (p = 0.02), anti-T-cell globulin (p = 0.001), and tacrolimus treatment (p = 0.02). DLBCL subtypes had similar overall survival. Five-year overall survival was 42% in all treated patients. Independent poor prognostic factors were older age, B symptoms, ECOG 2-4, kidney/pancreas/heart recipients, T-cell lymphoma, and HCV-infection. CONCLUSIONS With long follow-up, a large part of PTLD is EBV-negative, due to a high proportion of T-cell lymphomas and low of polymorphic PTLD. EBV-negative PTLD have a different clinical presentation. HCV may play an aetiological role in late-onset PTLD and was revealed as a new prognostic factor for inferior survival that needs to be confirmed in larger studies. The heavier immunosuppression in non-kidney transplantations seems to play a role in the development of non-germinal centre DLBCL. DLBCL cell of origin subtype lacks prognostic importance in the transplant setting.

Abstract
Post-transplant lymphoproliferative diseases (PTLD) are heterogeneous lymphoid disorders ranging from indolent polyclonal proliferations to aggressive lymphomas that complicate solid organ or hematopoietic transplantation. Risk factors for PTLD include viral infections, degree of immunosuppression, recipient age and race, allograft type, and host genetic variations. Clinically, extra-nodal disease is common including 10-15 % presenting with central nervous system (CNS) disease. Most PTLD cases are B cell (5-10 % T/NK cell or Hodgkin lymphoma), while over one-third are EBV-negative. World Health Organization (WHO) diagnostic categories are: early lesions, polymorphic, and monomorphic PTLD; although in practice, a clear separation is not always possible. Therapeutically, reduction in immunosuppression remains a mainstay, and recent data has documented the importance of rituximab +/- combination chemotherapy. Therapy for primary CNS PTLD should be managed according to immunocompetent CNS paradigms. Finally, novel treatment strategies for PTLD have emerged, including adoptive immunotherapy and rational targeted therapeutics (e.g., anti-CD30 based therapy and downstream signaling pathways of latent membrane protein-2A).

Abstract
Three cases of Epstein-Barr virus (EBV)-negative post-transplant lymphoproliferative disease that occurred 6 to 8 years after renal transplantation are reported. The patients respectively had gastric mucosa-associated lymphoid tissue lymphoma, gastric diffuse large B-cell lymphoma, and atypical Burkitt lymphoma. Absence of EBV in the tissue samples was demonstrated by both in situ hybridization for EBV early RNA and polymerase chain reaction for EBV DNA. Patients were treated with reduction in immunosuppression and combined chemotherapy plus an anti-CD20 monoclonal antibody, rituximab. Despite the reduction in immunosuppression, patients had stable renal functions without loss of graft functions. The patient with atypical Burkitt lymphoma had an abnormal karyotype, did not respond to treatment completely, and died due to disease progression. The other patients are still alive and in remission 5 and 3 years after diagnosis, respectively. EBV-negative post-transplant lymphoproliferative diseases are usually late-onset and are reported to have poor prognosis. Thus, reduction in immunosuppression is usually not sufficient for treatment and more aggressive approaches like rituximab with combined chemotherapy are required.

Abstract
INTRODUCTION Among possible complications of transplantation the post-transplant lymphoproliferative disease due to immunosuppressive therapy is of paramount importance. In most cases the direct modulating effect of Epstein-Barr virus on immune cells can be documented. AIM The aim of the authors was to evaluate the incidence os post-transplant lymphoproliferative diseases in pediatric transplant patients in Hungary. METHOD The study group included kidney, liver and lung transplant children followed up at the 1st Department of Pediatrics, Semmelweis University, Budapest and stem cell transplant children at Szent László Hospital, Budapest. Data were collected from 78 kidney, 109 liver and 17 lung transplant children as well as from 243 children who underwent allogenic stem cell transplantation. RESULTS Between 1998 and 2012, 13 children developed post-transplant lymphoproliferative disorder (8 solid organ transplanted and 5 stem cell transplanted children). The diagnosis was based on histological findings in all cases. Mortality was 3 out of the 8 solid organ transplant children and 4 out of the 5 stem cell transplant children. The highest incidence was observed among lung transplant children (17.6%). CONCLUSIONS These data indicate that post-transplant lymphoproliferative disease is a rare but devastating complication of transplantation in children. The most important therapeutic approaches are reduction of immunosuppressive therapy, chemotherapy and rituximab. Early diagnosis may improve clinical outcome and, therefore, routine polymerase chain reaction screening for Epstein-Barr virus of high risk patients is recommended.

Abstract
BACKGROUND Primary central nervous system (PCNS) post-transplant lymphoproliferative disorder (PTLD) is a rare complication of solid organ transplantation and is typically an Epstein-Barr virus (EBV)-induced B-cell CD20+ lymphoma. The modalities of treatment include reduction in immunosuppression, cranial radiotherapy (CRT), intravenous and intrathecal rituximab when CD20 is expressed on B-lymphocytes and PTLD cells, and chemotherapy. CASE-DIAGNOSIS/TREATMENT We report the successful treatment of EBV-driven PCNS PTLD by reduction in immunosuppression (RI), CRT, and intravenous rituximab. Our patient was an 11-year-old boy with a living-related renal transplant for end-stage renal failure (ESRF) secondary to posterior urethral valves (PUV) and bilateral renal dysplasia (BRD) and on triple immunosuppression with prednisolone, tacrolimus, and azathioprine who had a rising EBV load, which was managed with reduction in tacrolimus dose, withdrawal of azathioprine, and introduction of mycophenolate mofetil (MMF). CONCLUSIONS The patient presented 7 years post-transplant with a seizure and abnormal neurology secondary to polymorphous hyperplastic lesions in the brain, which responded to rituximab and CRT.

Abstract
Patients after solid organ transplantation (SOT) carry a substantially increased risk to develop malignant lymphomas. This is in part due to the immunosuppression required to maintain the function of the organ graft. Depending on the transplanted organ, up to 15% of pediatric transplant recipients acquire posttransplant lymphoproliferative disease (PTLD), and eventually 20% of those succumb to the disease. Early diagnosis of PTLD is often hampered by the unspecific symptoms and the difficult differential diagnosis, which includes atypical infections as well as graft rejection. Treatment of PTLD is limited by the high vulnerability towards antineoplastic chemotherapy in transplanted children. However, new treatment strategies and especially the introduction of the monoclonal anti-CD20 antibody rituximab have dramatically improved outcomes of PTLD. This review discusses risk factors for the development of PTLD in children, summarizes current approaches to therapy, and gives an outlook on developing new treatment modalities like targeted therapy with virus-specific T cells. Finally, monitoring strategies are evaluated.

Abstract
We performed a multicenter, International analysis of solid organ transplant (SOT)-related primary central nervous system (PCNS) posttransplant lymphoproliferative disease (PTLD). Among 84 PCNS PTLD patients, median time of SOT-to-PTLD was 54 months, 79% had kidney SOT, histology was monomorphic in 83% and tumor was EBV+ in 94%. Further, 33% had deep brain involvement, 10% had CSF involvement, while none had ocular disease. Immunosuppression was reduced in 93%; additional first-line therapy included high-dose methotrexate (48%), high-dose cytarabine (33%), brain radiation (24%) and/or rituximab (44%). The overall response rate was 60%, while treatment-related mortality was 13%. With 42-month median follow-up, three-year progression-free survival (PFS) and overall survival (OS) were 32% and 43%, respectively. There was a trend on univariable analysis for improved PFS for patients who received rituximab and/or high-dose cytarabine. On multivariable Cox regression, poor performance status predicted inferior PFS (HR 2.61, 95% CI 1.32-5.17, p = 0.006), while increased LDH portended inferior OS (HR 4.16, 95% CI 1.29-13.46, p = 0.02). Moreover, lack of response to first-line therapy was the most dominant prognostic factor on multivariable analysis (HR 8.70, 95% CI 2.56-29.57, p = 0.0005). Altogether, PCNS PTLD appears to represent a distinct clinicopathologic entity within the PTLD spectrum that is associated with renal SOT, occurs late, is monomorphic and retains EBV positivity.

Abstract
Post-transplantation lymphoproliferative disorders (PTLD) are the second most frequent malignancies after solid organ transplantation and cover a wide spectrum ranging from polyclonal early lesions to monomorphic lymphoma. Available treatment modalities include immunosuppression reduction, immunotherapy with anti-B-cell monoclonal antibodies, chemotherapy, antiviral therapy, cytotoxic T-cell therapy as well as surgery and irradiation. Owing to the small number of cases and the heterogeneity of PTLD, current treatment strategies are mostly based on case reports and small, often retrospective studies. Moreover, many studies on the treatment of PTLD have involved a combination of different treatment options, complicating the evaluation of individual treatment components. However, there has been significant progress over the last few years. Three prospective phase II trials on the efficacy of rituximab monotherapy have shown significant complete remission rates without any relevant toxicity. A prospective, multicenter, international phase II trial evaluating sequential treatment with rituximab and CHOP-based chemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisone) is ongoing and preliminary results have been promising. Cytotoxic T-cell therapy targeting Epstein-Barr virus (EBV)-infected B cells has shown low toxicity and high efficacy in a phase II trial and will be a future therapeutic option at specialized centers. Here, we review the currently available data on the different treatment modalities with a focus on PTLD following solid organ transplantation in adult patients.

Abstract
PURPOSE Post-transplantation lymphoproliferative disorder (PTLD) is associated with significant mortality in kidney transplant recipients. We conducted a prospective survey of the occurrence of PTLD in a French nationwide population of adult kidney recipients over 10 years. PATIENTS AND METHODS A French registry was established to cover a nationwide population of transplant recipients and prospectively enroll all adult kidney recipients who developed PTLD between January 1, 1998, and December 31, 2007. Five hundred patient cases of PTLD were referred to the French registry. The prognostic factors for PTLD were investigated using Kaplan-Meier and Cox analyses. RESULTS Patients with PTLD had a 5-year survival rate of 53% and 10-year survival rate of 45%. Multivariable analyses revealed that age > 55 years, serum creatinine level > 133 μmol/L, elevated lactate dehydrogenase levels, disseminated lymphoma, brain localization, invasion of serous membranes, monomorphic PTLD, and T-cell PTLD were independent prognostic indicators of poor survival. Considering five variables at diagnosis (age, serum creatinine, lactate dehydrogenase, PTLD localization, and histology), we constructed a prognostic score that classified patients with PTLD as being at low, moderate, high, or very high risk for death. The 10-year survival rate was 85% for low-, 80% for moderate-, 56% for high-, and 0% for very high-risk recipients. CONCLUSION This nationwide study highlights the prognostic factors for PTLD and enables the development of a new prognostic score. After validation in an independent cohort, the use of this score should allow treatment strategies to be better tailored to individual patients in the future.

Abstract
The gut is the most common extranodal site where lymphomas arise. Although all histological lymphoma types may develop in the gut, small and large B-cell lymphomas predominate. The sometimes unexpected finding of a lymphoid lesion in an endoscopic biopsy of the gut may challenge both the clinician (who is not always familiar with lymphoma pathogenesis) and the pathologist (who will often be hampered in his/her diagnostic skill by the limited amount of available tissue). Moreover, the past 2 decades have spawned an avalanche of new data that encompasses both the function of the reactive B-cell as well as the pathogenic pathways that lead to its neoplastic counterpart, the B-cell lymphoma. Therefore, this review aims to offer clinicians an overview of B-cell lymphomas in the gut, and their pertinent molecular features that have led to new insights regarding lymphomagenesis. It addresses the question as how to incorporate all presently available information on normal and neoplastic B-cell differentiation, and how this knowledge can be applied in daily clinical practice (e.g., diagnostic tools, prognostic biomarkers or therapeutic targets) to optimalise the managment of this heterogeneous group of neoplasms.

Abstract
BACKGROUND Late-onset post-transplantation lymphoproliferative disorders (PTLDs) occur 1 year after transplantation and are associated with poor prognosis. Initial treatment usually involves a reduction in immunosuppressive treatment. While early-onset PTLDs have a good prognosis following RI, this approach is generally inadequate for late-onset PTLDs. We assessed the specific outcome of late-onset PTLDs after kidney transplantation during the past three decades. METHODS We reviewed the clinical and biological data of 52 kidney transplant recipients who developed late-onset PTLDs at our centre between 1980 and 2010. We compared clinical features, long-term outcome and renal prognosis of late-onset PTLDs both before and after the era of rituximab. RESULTS Before 2000, 38% of the patients underwent surgery and 76% received chemotherapy either immediately or after surgery. After 2000, rituximab was administrated to 70% of the patients either alone (23%) or in combination with chemotherapy (77%). Chemotherapy alone was administrated in 26% of the cases. Before and after 2000, complete remission was achieved in 38 and 87% of the cases, respectively (P = 0.0005). The 5-year overall survival (OS) was 33.3 and 69% (P = 0.003), and 5-year disease-free survival was 37.5 and 80%, respectively (P = 0.19). Renal function was preserved in 70% of the cases at the end of the follow-up. CONCLUSIONS This study shows an increase in OS and low graft loss for patients with late-onset PTLDs during the last decade, which may be attributed to multiple changes in clinical practice, including a more standardized treatment and the use of rituximab in combination with chemotherapy.

Abstract
Recipients of liver transplantation (LT) have a higher overall risk (2-3 times on average) of developing de novo malignancies than the general population, with standardized incidence ratios ranging from 1.0 for breast and prostate cancers to 3-4 for colon cancer and up to 12 for esophageal and oropharyngeal cancers. Aside from immunosuppression, other identified risk factors for de novo malignancies include the patient's age, a history of alcoholic liver disease or primary sclerosing cholangitis, smoking, and viral infections with oncogenic potential. Despite outcome studies showing that de novo malignancies are major causes of mortality and morbidity after LT, there are no guidelines for cancer surveillance protocols or immunosuppression protocols to lower the incidence of de novo cancers. Patient education, particularly for smoking cessation and excess sun avoidance, and regular clinical follow-up remain the standard of care. Further research in epidemiology, risk factors, and the effectiveness of screening and management protocols is needed to develop evidence-based guidelines for the prevention and treatment of de novo malignancies.

Abstract
BACKGROUND Posttransplant lymphoproliferative disorder (PTLD) is a well-established complication of immunosuppression. The involvement of the gastrointestinal (GI) tract occurs in 25% of all cases of PTLD. Fortunately, surgical intervention is seldom required. We report our experience of surgical treatment of complicated GI-PTLD after liver transplantation (LTx). METHODS A retrospective analysis of 5677 adult patients who underwent LTx between 1983 and 2009 was conducted. RESULTS Thirty-six patients presented with GI-PTLD. Sixteen patients presented with complications associated with GI-PTLD requiring emergency surgery. The average (SD) time from LTx to GI surgery was 7.9 (5.8) years (range, 4 months to 17 years). Indications for surgical intervention were small bowel obstruction (seven cases), perforation (six cases), and GI bleeding (three cases). Most GI-PTLD occurred in the small bowel or right colon (81%). In addition to the surgery, treatment of PTLD consisted of reduction of immunosuppression, use of rituximab (n=10), and systemic chemotherapy (n=7). Overall mortality was 69%, with most of the deaths occurring within 8 months after emergency laparotomy. GI bleeding and perforation were associated with higher mortality (>66%). Despite higher early mortality in the surgical group, no differences on long-term outcome were observed between patients with GI-PTLD who required surgery and those who did not (P=0.371). CONCLUSIONS In summary, GI-PTLD requiring surgical intervention is an extremely rare condition with high early mortality. Most of the cases are monoclonal, present a late onset, and involve the lower GI tract. Intestinal obstruction is the main indication for surgical intervention and is associated with better prognosis.

Abstract
OPINION STATEMENT Post transplant lymphoproliferative disorder (PTLD) is a heterogeneous disease that may occur in recipients of solid organ transplants (SOT) and hematopoietic stem cell transplant. The risk of lymphoma is increased 20-120% compared with the general population with risk dependent in part on level of immune suppression. In addition, recent data have emerged, including HLA and cytokine gene polymorphisms, regarding genetic susceptibility to PTLD. Based on morphologic, immunophenotypic, and molecular criteria, PLTD are classified into 4 pathologic categories: early lesions, polymorphic, monomorphic, and classical Hodgkin lymphoma. Evaluation by expert hematopathology is critical in establishing the diagnosis. The aim of therapy for most patients is cure with the concurrent goal of preservation of allograft function. Given the pathologic and clinical heterogeneity of PTLD, treatment is often individualized. A mainstay of therapy remains reduction of immune suppression (RI) with the level of reduction being dependent on several factors (e.g., history of rejection, current dosing, and type of allograft). Outside of early lesions and/or low tumor burden, however, RI alone is associated with cure in a minority of subjects. We approach most newly-diagnosed polymorphic and monomorphic PTLDs similarly using frontline single-agent rituximab (4 weeks followed by abbreviated maintenance) in conjunction with RI. Frontline combination chemotherapy may be warranted for patients with high tumor burden in need of prompt response or following failure of RI and/or rituximab. Due to chemotherapy-related complications in PTLD, especially infectious, we advocate comprehensive supportive care measures. Surgery or radiation may be considered for select patients with early-stage disease. For PTLD subjects with primary CNS lymphoma, we utilize therapeutic paradigms similar to immunocompetent CNS lymphoma using high-dose methotrexate-based therapy with concurrent rituximab therapy and sequential high-dose cytarabine. Finally, novel therapeutic strategies, especially adoptive immunotherapy, should continued to be explored.

Abstract
De novo malignancies represent an increasing concern in the transplant population, particularly as long-term graft and patient survival improves. EBV-associated B-cell lymphoma in the setting of PTLD is the leading malignancy in children following solid organ transplantation. Therapeutic strategies can be categorized as pharmacologic, biologic, and cell-based but the variable efficacy of these approaches and the complexity of PTLD suggest that new treatment options are warranted. Here, we review current therapeutic strategies for treatment of PTLD. We also describe the life cycle of EBV, addressing the viral mechanisms that contribute to the genesis and persistence of EBV+ B-cell lymphomas. Specifically, we focus on the oncogenic signaling pathways activated by the EBV LMP1 and LMP2a to understand the underlying mechanisms and mediators of lymphomagenesis with the goal of identifying novel, rational therapeutic targets for the treatment of EBV-associated malignancies.

Abstract
We report a case of a 67-year-old man who experienced allograft dysfunction following a renal transplantation from a donation after cardiac death. The postoperative course was initially complicated by episodes of E. coli urinary sepsis causing pyrexia and a raised creatinine level. Ultrasound scanning 5 weeks posttransplant revealed mild hydronephrosis with several parenchymal cystic areas measuring up to 2 cm with appearances suggestive of fungal balls. Aspirated fluid again grew Escherichia coli, and this was treated with the appropriate antimicrobial therapy. The patient continued to have episodes of culture-negative sepsis; therefore, a computed tomography scan was performed 6 months posttransplant, which revealed multiple lesions in the renal cortex as well as liver and spleen. Subsequent biopsy revealed an Epstein-Barr virus-driven lymphoproliferation consistent with a polymorphic posttransplantation lymphoproliferative disorder (PTLD). This rare case of PTLD presenting as multiple renal, hepatic and splenic lesions emphasizes the need for a high index of clinical suspicion for this condition. Abnormal para-renal allograft masses should be biopsied to allow swift and effective management of a disease that can disseminate and become significantly more challenging to manage.

Abstract
BACKGROUND Post-transplant lymphoproliferative disorder (PTLD) is a complication of organ transplantation. The risk of developing PTLD varies depending on a number of factors, including the organ transplanted and the degree of immunosuppression used. METHODS We report a retrospective analysis of 35 patients with PTLD treated at our center after lung transplantation. Of 705 patients who received allografts, 34 (4.8%) developed PTLD. One patient underwent transplantation elsewhere and was treated at our center. RESULTS PTLD involved the allograft in 49% of our patients and the gastrointestinal (GI) tract lumen in 23%. Histologically, 39% of tumors were monomorphic and 48% polymorphic. The time to presentation defined the location and histology of disease. Of 17 patients diagnosed within 11 months of transplantation, PTLD involved the allograft in 12 (71%) and the GI tract in 1 (p = 0.01). This "early" PTLD was 85% polymorphic (p = 0.006). Conversely, of the 18 patients diagnosed more than 11 months after transplant, the lung was involved in 5 (28%) and the GI tract in 7 (39%; p = 0.01). "Late" PTLD was 71% monomorphic (p = 0.006). Median overall survival after diagnosis was 18.57 months. Overall survival did not differ between all lung transplant recipients and those who developed PTLD. CONCLUSIONS PTLD is an uncommon complication after lung transplantation, and its incidence declined remarkably in the era of modern immunosuppression. We report several factors that are important for predisposition toward, progression of, and treatment of PTLD after lung transplantation.

Abstract
Post-transplantation lymphoproliferative disorder (PTLD) with plasmacellular differentiation has been reported as a rare subtype of monomorphic B-cell post-transplant lympho-proliferation with histological and immunophenotypical features of plasmacytoma in the non-transplant population. Here we present clinical, laboratory and histopathological features, treatment and outcome of 8 patients from the German prospective PTLD registry. Clinically, extranodal manifestations were common while osteolytic lesions were rare and none of the patients had bone marrow involvement. Immunohistochemistry showed light chain restriction and expression of CD138 without CD20 expression in all samples. An association with Epstein-Barr virus was found in 3 out of 8 cases. We suggest that the Ann Arbor classification is most useful for this disease entity and report a generally good response to treatment including reduction of immuno-suppression, surgery and irradiation in localized disease and systemic chemotherapy analogous to plasmacell myeloma in advanced disease.

Abstract
Posttransplant lymphoproliferative disorders (PTLD) are a life-threatening complication following solid organ transplantation. Many posttransplant lymphomas develop from the uncontrolled proliferation of Epstein-Barr virus (EBV)-infected B-cells, whereas EBV-negative PTLDs were increasingly recognized within the past decade. Major risk factors for the development of PTLDs after liver transplantation are immunosuppressive therapy and the type of underlying disease: viral hepatitis, autoimmune liver disease, or alcoholic liver cirrhosis contribute to an increased risk for PTLD. Therapeutic regimens include reduction of immunosuppression, the anti-CD20 antibody rituximab, and chemotherapy, as well as new approaches using interferon-α and anti-interleukin-6 antibodies. Despite the different therapeutic regimens, mortality from PTLD remains high. Therefore, it is of major importance to identify patients at risk at an early stage of the disease. In this review, risk factors for PTLD development after liver transplantation, clinical presentation, diagnosis, and therapy are discussed.

Abstract
Patients who undergo Epstein-Barr virus (EBV) seromismatch (D+/R-) transplants have a higher risk for the development of post-transplant lymphoproliferative disorder (PTLD). Adult renal transplant recipients at a single institution were prospectively monitored for EBV during the first year post-transplant. Over a 2-year period, 34 patients (7.78%) were identified as being EBV D+/R-recipients. Patients who developed symptoms or had persistent viremia were pre-emptively administered rituximab. Six recipients were discharged without monitoring on the protocol. Of those six, three (50%) developed PTLD and all three lost their grafts. Twenty (60.6%) of the 34 recipients developed viremia during the first year post-transplant. Of the recipients who became viremic, six (30%) received rituximab. None of the six who received rituximab-developed PTLD. We found that recipients who were not monitored on the protocol were more likely to have PTLD and graft loss compared to those who were (p = 0.008). Post-transplant monitoring of adults who undergo EBV D+/R-kidney transplants for viremia and symptoms associated with EBV infection may prompt intervention which reduces the incidence of PTLD within the first year. Use of rituximab in preventing PTLD among patients with primary EBV infection requires further prospective study to determine its overall safety and efficacy.

Abstract
The herpes viruses are responsible for a wide range of diseases in patients following transplant, resulting from direct viral effects and indirect effects, including tumor promotion. Effective treatments and prophylaxis exist for the neurotropic herpes viruses HSV-1, HSV-2, varicella zoster virus, and possibly HHV-6. Antivirals seem to be less effective at prevention of the tumor-promoting effects of Epstein-Barr virus and HHV-8. Reduction in immunosuppression is the cornerstone to treatment of many diseases associated with herpes virus infections.

Abstract
Lymphoma is an increasingly recognized complication of tumor necrosis factor (TNF) inhibition for the treatment of autoimmune and inflammatory disease; the majority of these cases are non-Hodgkin lymphomas (NHL). The impact of withdrawing TNF inhibition therapy in cases of lymphoma is not well described. A woman with Crohn's disease (CD) was diagnosed with Hodgkin lymphoma (HL) and subsequently went into remission with standard chemotherapy. Her CD later worsened, requiring initiation of adalimumab, a TNF inhibitor. Ten months later, she was found to have recurrence of HL. When she opted against additional treatment for the lymphoma, the TNF inhibitor was discontinued. Three months later, the measurable sites of disease had completely regressed. It can be concluded that HL is a potential complication of treatment with TNF inhibitors. Withdrawal of immunosuppression may be a consideration for patients treated for lymphoproliferative disorders including HL. Maintenance of an intact immune system may be important for prevention of lymphoma relapse. Further understanding of this complex interaction will help clinicians determine in which patients these agents have a favorable risk-benefit ratio.

Abstract
Epstein-Barr virus (EBV) is a gammaherpesvirus that infects a large fraction of the human population. Primary infection is often asymptomatic but results in lifelong infection, which is kept in check by the host immune system. In some cases, primary infection can result in infectious mononucleosis. Furthermore, when host-virus balance is not achieved, the virus can drive potentially lethal lymphoproliferation and lymphomagenesis. In this review, we describe the biology of EBV and the host immune response. We review the diagnosis of EBV infection and discuss the characteristics and pathogenesis of infectious mononucleosis. These topics are approached in the context of developing therapeutic and preventative strategies.

Abstract
Post-transplant lymphoproliferative disorder (PTLD) has been associated with high mortality, but recent anecdotal survival appeared better. From 1988 to 2010, the NAPRTCS registry had 235 registered PTLD cases. We sent a special 25-point questionnaire study to the NAPRTCS centers with the most recent 150 cases to obtain additional follow-up data not collected in the master registry, our objective being to determine the recent outcomes after PTLD and determine prognostic factors. We received 92 completed responses, in which only 12 (13%) deaths were reported, 2 from nonmedical causes, 10 with a functioning graft. Kaplan-Meier-calculated patient survival was 90.6% at 1 year and 87.4% at 3, 4 and 5 years post-PTLD. Graft survival post-PTLD was 81.8% at 1 year, 68.0% at 3 years and 65.0% at 5 years. Seven patients received a retransplant after PTLD, with no PTLD recurrence reported. Using all 235 PTLD cases, the covariates associated with better patient survival were more recent year of PTLD diagnosis (adjusted hazard ratio AHR 0.86, p < 0.001), and with worse survival were late PTLD (AHR 1.98, p = 0.0176) and patient age above 13 at PTLD (AHR 3.43, p value 0.022). In children with kidney transplants, patient survival has improved with more recent PTLDs.

Abstract
Malignancy is an important complication of thoracic organ transplantation and is associated with significant morbidity and mortality. Lung transplant recipients are at greater risk for cancer than immunocompetent persons, with cancer-specific incidence rates up to 60-fold higher than the general population. The increased risk for cancer is attributed to neoplastic properties of immunosuppressive medications, oncogenic viruses, and cancer-specific risk factors. This article addresses the epidemiology, presentation, and treatment of the most common malignancies after lung transplantation, including skin cancer, posttransplant lymphoproliferative disorder, and bronchogenic carcinoma.

Abstract
Development of secondary malignancies is a well-known complication of solid organ transplant, with skin cancer and lymphoproliferative disorders being most frequently observed. Posttransplant lymphoproliferative disorders, caused by diminished immune surveillance, represent a broad spectrum of pathological and clinical disorders, ranging from benign conditions to very aggressive lymphomas. Here we review treatment options for adult patients experiencing posttransplant lymphoproliferative disorders following solid organ transplant.

Abstract
Post-transplantation lymphoproliferative disorders (PTLD) are a heterogenous group of abnormal lymphoid proliferations that occur after solid organ transplant (SOT) or hematopoietic transplantation. PTLDs consist of a disease spectrum ranging from hyperplasia to aggressive lymphomas with 60-70% being Epstein-Barr virus positive. The majority of cases are B-cell, although 10-15% are of T-cell origin or rarely Hodgkin lymphoma. Recent SOT series suggest PTLD occurs at a median of 36-40 months after transplant. Clinically, extra-nodal disease is common (up to 75-85%) including CNS involvement, which is seen in 10-15% of all cases. Since the first report over 40 years ago, PTLD has remained one of the most morbid complications associated with SOT. However, recent data suggests improved survival in the modern era, especially with the integration of early rituximab-based therapy. These studies utilized first line rituximab (+/- chemotherapy) together with reduced immune suppression (RI) for monomorphic and polymorphic PTLD. It will be critical in future studies to determine which PTLDs are most amenable to initial therapy with RI alone, versus RI/rituximab, versus RI/rituximab/chemotherapy. Additionally, novel therapeutics, such as adoptive immunotherapy, should continue to be explored.

Abstract
Reduction of immunosuppression (RI) is commonly used to treat posttransplant lymphoproliferative disorder (PTLD) in solid organ transplant recipients. We investigated the efficacy, safety and predictors of response to RI in adult patients with PTLD. Sixty-seven patients were managed with RI alone and 30 patients were treated with surgical excision followed by adjuvant RI. The response rate to RI alone was 45% (complete response-37%, partial response-8%). The relapse rate in complete responders was 17%. Adjuvant RI resulted in a 27% relapse rate. The acute rejection rate following RI-containing strategies was 32% and a second transplant was feasible without relapse of PTLD. The median survival was 44 months in patients treated with RI alone and 9.5 months in patients who remained on full immunosuppression (p = 0.07). Bulky disease, advanced stage and older age predicted lack of response to RI. Survival analysis demonstrated predictors of poor outcome-age, dyspnea, B symptoms, LDH level, hepatitis C, bone marrow and liver involvement. Patients with none or one of these factors had a 3-year overall survival of 100% and 79%, respectively. These findings support the use of RI alone in low-risk PTLD and suggest factors that predict response and survival.

Abstract
EBV is associated with various malignancies in patients with acquired or induced immune impairment. EBV-SMT is very uncommon in immunocompromised patients, and a kidney localization has been described only anecdotally. We report the case of a 17-yr-old kidney transplant recipient diagnosed as having an EBV-SMT inside the renal graft, which was successfully managed by minimizing isolated immunosuppression.

Abstract
PTLD is a major complication after transplantation. Treatment options for PTLD are not standardized, usually sequential, starting with reduction in immunosuppression. Recently, we have used a dual combination of rituximab and reduced dose chemotherapy (R/C) directly after failed RI. We retrospectively identified 30 pediatric PTLD cases across four organ systems at our center from 1995 to 2008. We assessed recent outcomes of PTLD in children, comparing the responses to different regimens. Two-yr failure-free survival was best in renal and heart recipients (80-88%), followed by liver (57%) and lung (0%). Of note, two patients were Epstein-Barr peripheral blood viral load low positive but tumor EBER negative. Three patients had no detectable viral load but were EBER positive. The R/C regimen (n = 8) had the highest CR rate (100%), low recurrence (12%) and lowest mortality (12%). Interferon (n = 4) had 75% CR, 33% recurrence and 25% mortality. Rituximab/prednisone (n = 5) had 80% CR, 50% recurrence and 20% mortality. Other chemotherapy (n = 7, including all 4 T-cell PTLDs) had 57% CR, 0% recurrence and 14% mortality. Direct dual R/C combination therapy after failed RI is effective and offers another treatment option for B-cell PTLD.
