Wilms tumor is the most common renal tumor of childhood. However, other epithelial, mesenchymal, and neuroectodermal neoplasms may also arise in the kidney during childhood, several of which show specific age distributions; in the 1st year of life, mesoblastic nephroma and rhabdoid tumor are more common, whereas renal cell carcinoma, primitive neuroectodermal tumor, and anaplastic Wilms tumors are relatively more frequent in older children and adolescents. The aim of this study is to describe the spectrum of renal tumors in children aged clinical trials of renal tumors in childhood. There were 67 (4.6%) tumors in children aged 10-16 years: 50 Wilms tumors (74.6%), 10 (14.9%) renal cell carcinomas, 3 (4.5%) renal medullary carcinomas, 2 (3%) primitive neuroectodermal tumors, 1 clear cell sarcoma of kidney, and 1 desmoplastic small round cell tumor. Fourteen percent of the Wilms tumors in this age group had diffuse anaplasia. Among the 10 renal cell carcinomas, 4 were associated with t(Xp-11.2), 3 were of papillary type II, 1 was papillary type I, 1 was clear cell type, and 1 was unclassified. Five-year overall survival for Wilms tumor was 63% (43% for anaplastic tumors), significantly lower than reported overall survival for all pediatric Wilms tumors. Only 40% of patients with renal cell carcinoma survived, and all patients with other tumors died.

Incidence Survival A B S T R A C T More than 5000 cases of malignant renal tumour diagnosed in children under the age of 15 years during the period 1978-1997 in Europe, were extracted from the database of the Automated Childhood Cancer Information System (ACCIS). In 1988-1997 the age-standardised incidence rate of childhood renal tumours in Europe was 8.8 per million, with significant differences between regions. Wilms' tumour (WT, M-8960) accounted for 93% of renal tumours and about 7% were bilateral. The incidence rates of WT increased over the 20 years, by 0.7% per year. European 5-year survival for children diagnosed with WT in 1988-1997 was 85%, ranging from 73% in the East to 91% in the North. Patients in the age group 0-3 years at diagnosis had a more favourable prognosis (5-year survival 87%) than those diagnosed later (81%), P < 0.0001. Patients with unilateral WT (n = 2085) had better 5-year survival (85%) than 154 patients with bilateral tumours (76%), P = 0.003. Five-year survival for 64 patients with clear cell sarcoma of kidney was 68%, for 43 patients with rhabdoid tumour of kidney it was 23%, and for 56 patients with renal cell carcinoma it was 87%. For combined European data, 5-year survival for WT increased from 73% in 1978-1982 to 87% in 1993-1997 and the increase was significant in three out of five regions (East, North and West). Further development and exploitation of the ACCIS database will benefit clinical management and aetiological studies.
Characteristics and Outcome of Children with Renal Cell Carcinoma: A Narrative Review
Cancers, 2020
Pediatric renal cell carcinoma (RCC) is a rare type of kidney cancer, most commonly occurring in teenagers and young adolescents. Few relatively large series of pediatric RCC have been reported. Knowledge of clinical characteristics, outcome and treatment strategies are often based on the more frequently occurring adult types of RCC. However, published pediatric data suggest that clinical, molecular and histological characteristics of pediatric RCC differ from adult RCC. This paper summarizes reported series consisting of ≥10 RCC pediatric patients in order to create an up-to-date overview of the clinical and histopathological characteristics, treatment and outcome of pediatric RCC patients.

Around 6% of all childhood malignancies represent renal tumors, of which a majority includes Wilms tumor (WT). Although survival rates have improved over the last decades, specific patients are still at risk for adverse outcome. In the Netherlands, since 2015, pediatric oncology care for renal tumors has been centralized in the Princess Má xima Center for Pediatric Oncology. Here, we describe experiences of the first 5 years of centralized care and explore whether this influences the epidemiological landscape by comparing data with the Netherlands Cancer Registry (NCR). We identified all patients <19 years with a renal mass diagnosed between 01-01-2015 and 31-12-2019 in the Princess Má xima Center. Epidemiology, characteristics and management were analyzed. We identified 164 patients (including 1 patient who refused consent for registration), in our center with a suspicion of a renal tumor. The remaining 163 cases included WT (n = 118)/cystic partially differentiated nephroblastoma (n = 2)/nephrogenic rests only (n = 6) and non-WT (n = 37). In this period, the NCR included 138 children, 1 17-year-old patient was not referred to the Princess Má xima Center. Central radiology review (before starting treatment) was performed in 121/163 patients, and central pathology review in 148/152 patients that underwent surgery. Treatment stratification, according to SIOP/EpSSG protocols was pursued based on multidisciplinary consensus. Preoperative chemotherapy was administered in 133 patients, whereas 19 patients underwent upfront surgery. Surgery was performed in 152 patients, and from 133 biomaterial was stored. Centralization of care for children with renal tumors led to referral of all but 1 new renal tumor cases in the Netherlands, and leads to referral of very rare subtypes not registered in the NCR, that benefit from high quality diagnostics and
Renal Cell Carcinoma in Children: Experience of a Single Center

Objective: To evaluate the clinical features and outcome of children withrenal cell carcinoma (RCC). Patients and Methods: Eleven patients with RCC who were diagnosed between 1972 and 2004 were retrospectively analyzed. Clinical features, histopathology, treatment regimens and outcomes of the patients were evaluated. Results: The male/female ratio was 3:8, with a median age of 10 years. The stage distribution was as follows: 3 patients in stage I, 1 patient in stage II, 3 patients in stage IIIb, and 4 patients in stage IV. Five of 7 patients with stage II-IV received an actinomycin D-based regimen, one received a cisplatin-based regimen, and the other was given 5-fluorouracil (5-FU). In the last patient, interferon-α was given in combination with 5-FU; 1 of the patients on the actinomycin D regimen received interferon-α as well. All of the stage I patients are alive without disease. Three patients with stage IIIb, stage IV and stage II disease are alive without disease 8, 14 and 26 ...
