Recurrence of Renal Cell Cancer After Renal Transplantation in a Multicenter French Cohort

Background Renal cancer accounts for 3% of adult malignancies; renal cell carcinoma (RCC) represents 80% of all renal cancers, and is characterized by late recurrences. Recurrences after kidney transplantation are associated with a high mortality rate. We aimed to determine if recurrences are linked to tumor characteristics and to delays between diagnosis and transplantation. Methods We retrospectively analyzed data from French kidney-transplanted patients with medical histories of pretransplant renal cancer, focusing on the most common histological subtypes: clear cell and papillary cancers. Characteristics of the tumors, patients, and kidney transplantations were documented, and posttransplant patient survival was analyzed. Results Of 143 patients, 13 experienced cancer recurrence after kidney transplantation. The mean delay in recurrence was 3 ± 2.3 years posttransplantation, and the cumulative incidences of recurrence were 7.7% at 5 years and 14.9% at 10 years. The risk of recurrence was higher in patients with clear cell RCC (13% vs 0%, P = 0.015). There was no correlation between posttransplant recurrence and the interval before transplantation. Factors associated with a higher risk of cancer recurrence were histological clear cell RCC (P = 0.025), tumor stage pT2 (P = 0.002), and Fuhrman grade IV (P

We describe the clinicopathologic features of BKPyV-associated urologic carcinomas in a single-institution cohort. RESULTS: Among 4,772 kidney recipients during 1994 to 2014, 26 (0.5%) and 26 (0.5%) developed posttransplantation urothelial carcinomas (UCs) and renal cell carcinomas (RCCs), respectively, as of 2017. Six (27%) UCs but none of the RCCs expressed large T antigen (TAg). TAg-expressing UCs were high grade with p16 and p53 overexpression (P

Discussion MDSCs violently emerge in pathological conditions in an attempt to limit potentially harmful immune and inflammatory responses. Mechanisms supporting their expansion and survival are deeply investigated in cancer, in the perspective to reactivate specific antitumor responses and prevent their contribution to disease evolution. These findings will likely contribute to improve the targeting of MDSCs in anticancer immunotherapies, either alone or in combination with immune checkpoint inhibitors. New evidence indicates that the expansion of myeloid cell differentiation in pathology is subject to fine-tuning, as its...

The authors report 27 patients rendered surgically (N  = 23) or functionally (N = 4) anephric after kidney cancer operations. Sixteen patients had renal cell carcinoma (RCC, histologic subtype not specified) and 9 transitional cell carcinoma. No partial nephrectomies were done in the 7 T1 patients (5 due to severe preexisting chronic kidney dis ease (CKD) and 2 due to anatomic complexity). Only 4 patients underwent renal transplantation, all T1a RCC (

We present a case of a 22-year-old man with history of allogenic renal transplantation on immunosuppression, who underwent 18F-FDG-PET/CT to characterize a lesion in the transplanted kidney on ultrasonogram and contrast-enhanced computed tomography imaging. PET/CT revealed FDG avid lesion in the transplanted kidney and mural thickening involving the distal ileum, ileocecal junction, and ileocolic lymph nodes. Subsequent histopathological examination from the renal lesion revealed renal cell carcinoma in the transplanted kidney. Additionally, endoscopic biopsy from the ileal thickening revealed granulomatous inflammation, s...

ConclusionsThe role of the microbiome in genitourinary cancer is an emerging field that merits further studies. Translating microbiome research into clinical action will require incorporation of microbiome surveillance into ongoing and future clinical trials as well as expansion of studies to include metagenomic sequencing and metabolomics.Patient summaryThis review covers recent evidence that microbial populations that reside in the genitourinary tract—and were previously not known to exist—may influence the development of genitourinary malignancies including bladder, kidney, and prostate cancers. Furthermore,...

rta C Abstract Due to the increasing occurrence of renal cell carcinoma (RCC) in the general population and the high prevalence of chronic kidney disease among cancer patients, many people with a previous RCC may eventually require renal replacement therapy including kidney transplantation. They should accordingly be evaluated to assess their life expectancy and the risk that the chronic immunosuppressive therapy needed after grafting might impair their long-term outcome. Current guidelines on listing patients for renal transplantation suggest that no delay is required for subjects with small or incidentally disco...

We report that the disruption of excitation-contraction coupling contributes to impaired force generation in the mouse model of Sod1 deficiency. Briefly, we found a significant reduction in sarcoplasmic reticulum Ca2+ ATPase (SERCA) activity as well as reduced expression of proteins involved in calcium release and force generation. Another potential factor involved in EC uncoupling in Sod1-/- mice is oxidative damage to proteins involved in the contractile response. In summary, this study provides strong support for the coupling between increased oxidative stress and disruption of cellular excitation contraction mac...

Abstract Acute kidney injury (AKI) is a common complication in cancer patients and occurs in up to 30% of patients during their disease course. Multiple myeloma, leukemia/lymphoma, renal cell carcinoma, and hematopoietic stem cell transplantation are commonly associated with the development of AKI. Drugs used to treat various malignancies are also a common and notable cause of AKI in this population. Nephrology consultation is important to ensure proper and rapid diagnosis, as well as appropriate therapy and follow-up. In particular, knowledge of the nephrotoxicity of the various anticancer regimens employed is cr...

B. Tchounwou Kidney cancer ranks among the top 10 cancers in the United States. Although it affects both male and female populations, it is more common in males. The prevalence rate of renal cell carcinoma (RCC), which represents about 85% of kidney cancers, has been increasing gradually in many developed countries. Family history has been considered as one of the most relevant risk factors for kidney cancer, although most forms of an inherited predisposition for RCC only account for less than four percent. Lifestyle and other factors such as occupational exposure, high blood pressure, poor diet, and heavy cigarette s...
