The incidence of cancer recurrence and new cancer following commencement of dialysis in patients with prior cancers. Clin Kidney J 2022; 15:1770-1781. [PMID: 36003660 PMCID: PMC9394713 DOI: 10.1093/ckj/sfac124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Indexed: 11/17/2022] Open
Abstract
Background Patients with kidney failure have a higher cancer risk compared with the age-matched general population. However, the outcomes of incident dialysis patients with a prior cancer history are unknown. Methods Using Australia and New Zealand Dialysis and Transplant Registry data (2000–2019), the outcomes and survival probabilities of incident dialysis patients with prior cancers and having experienced a cancer recurrence or having developed a new cancer after dialysis commencement were described. Results Of 4912 patients with prior cancers before dialysis commencement, 323 (7%) and 343 (7%) patients experienced cancer recurrence or developed new cancers after dialysis initiation, respectively. The median time from dialysis commencement to cancer recurrence was 1.2 years [interquartile range (IQR) 0.5–2.8] and was 2.0 years (IQR 0.7–4.0) for new cancer occurrence. Of those with cancer recurrence, 80% presented with metastatic disease and one in two patients died from cancer, with a median time from cancer recurrence to death of 0.5 years (IQR 0.2–1.7). Of those who developed new cancer, urinary tract and respiratory cancers were the most frequent cancer types, with a median time from new cancer diagnosis to death of 1.3 years (IQR 0.4–3.1). The 3-year survival probabilities on dialysis following cancer recurrence and new cancer were 19% [95% confidence interval (CI) 15–24] and 41% (35–47), respectively. Conclusion Among incident dialysis patients with a prior cancer history, 14% experienced cancer recurrence or developed a new cancer. Patients who experienced cancer recurrence or developed new cancer have poor outcomes, with ˂50% surviving beyond 3 years. These findings suggest the need to have a greater understanding of the characteristics, cancer screening, treatment responses and reasons for commencing dialysis in patients with kidney failure and prior cancer history, which may help in the shared clinical decision-making process when considering dialysis for these patients.

[PMID: 28371054 DOI: 10.1111/ajt.14289] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2016] [Revised: 03/10/2017] [Accepted: 03/18/2017] [Indexed: 01/25/2023]
Abstract
Cancer risk is increased substantially in adult kidney transplant recipients, but the long-term risk of cancer in childhood recipients is unclear. Using the Australian and New Zealand Dialysis and Transplant Registry, the authors compared overall and site-specific incidences of cancer after transplantation in childhood recipients with population-based data by using standardized incidence ratios (SIRs). Among 1734 childhood recipients (median age 14 years, 57% male, 85% white), 289 (16.7%) developed cancer (196 nonmelanoma skin cancers, 143 nonskin cancers) over a median follow-up of 13.4 years. The 25-year cumulative incidences of any cancer were 27% (95% confidence intervals 24-30%), 20% (17-23%) for nonmelanoma skin cancer, and 14% (12-17%) for nonskin cancer (including melanoma). The SIR for nonskin cancer was 8.23 (95% CI 6.92-9.73), with the highest risk for posttransplant lymphoproliferative disease (SIR 45.80, 95% CI 32.71-62.44) and cervical cancer (29.4, 95% CI 17.5-46.5). Increasing age at transplantation (adjusted hazard ratio [aHR] per year 1.10, 95% CI 1.06-1.14), white race (aHR 3.36, 95% CI 1.61-6.79), and having a functioning transplant (aHR 2.27, 95% CI 1.47-3.71) were risk factors for cancer. Cancer risk, particularly for virus-related cancers, is increased substantially after kidney transplantation during childhood.

[PMID: 29100424 PMCID: PMC5652814 DOI: 10.18632/oncotarget.20781] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2017] [Accepted: 07/30/2017] [Indexed: 12/15/2022] Open
Abstract
The excess risk for cancer in kidney transplant recipients is substantial, but the allograft and patient survivals after cancer development are under-studied. This is a population-based cohort study of all primary live and deceased donor kidney transplant recipients in Australia and New Zealand between 1990-2012. The risks of overall graft loss and death with a functioning graft in kidney transplant recipients with and without incident cancer were determined using adjusted Cox regression analysis, with incident cancer considered as a time-varying covariate in the models. In those with incident cancer, types and cancer stage at diagnoses were reported. Of 12,545 transplant recipients followed for a median of 6.9 years (91,380 patient-years), 1184 (9.4%) developed incident cancers at a median of 5.8 years post-transplant. Digestive, kidney and urinary tract cancers were the most common cancer types, although digestive and respiratory tract cancers were more aggressive, with 40% reported as advanced cancers at time of cancer diagnosis. Cancer-related deaths accounted for approximately 80% of recipients with a prior cancer history. Compared with recipients with no prior cancer, the adjusted hazard ratios (HR) for overall graft loss and death with functioning graft were 4.34 (95%CI 3.90, 4.82; p<0.001) and 9.53 (95%CI 8.30, 10.95; <0.001) among those with a prior cancer. Incident cancer after kidney transplantation is a significant risk factor for death with a functioning graft, with the majority of deaths attributed to cancer. A greater understanding of the barriers to screening and treatment approaches following cancer diagnosis may lead to improve survival in kidney transplant recipients with cancer.

Abstract
Malignancy is the second most common single cause of death observed in organ transplant recipients. The excess cancer risk is related to intensity and duration of immunosuppressive therapy and inversely to recipient age. Immunodeficiency and (chronic/oncogenic) viral infections together constitute a major risk. Nonmelanoma skin cancer, Kaposi sarcoma, and posttransplant lymphoproliferative disease have standardized incidence ratios exceeding 10- or 50-fold. The mammalian target of rapamycin (mTOR) inhibitors, sirolimus and everolimus, are increasingly used after organ transplantation with potential advantages in virus-associated posttransplant malignancies as well as anti-cancer properties. Despite a seemingly clear mechanism of action and solid rationale for their use in cancer therapy, mTORis have met only modest success rates in clinical trials with advanced malignancies except for specific tumors, such as Kaposi sarcoma and mantle cell lymphoma. Because mTORis are primarily cytostatic, not cytotoxic, the observed clinical efficacy is a reflection of disease stabilization rather than tumor regression. Nonmelanoma skin cancers, in particular cutaneous squamous cell carcinoma, have the highest standardized incidence ratios in transplant recipients. Recent meta-analyses and randomized trials on secondary prevention of squamous cell carcinoma observed a reduction in cumulative tumor load, suggesting most benefit to be gained by early conversion to an mTOR inhibitor-based maintenance regime. There is ongoing debate on the mechanisms involved including withdrawal of the carcinogenic effects of calcineurin inhibitors and/or their impact on chronic (oncogenic) viral infections. At present, there is, however, insufficient evidence for the primary use of mTORis as protective agents against most other cancer types.
