Abstract

Background: Rhabdoid kidney tumors are a rare infant entity. We present a case series of 10 patients with this diagnosis in a period of 19 years at the National Cancer Institute of Peru.
Methods and Results: Descriptive and retrospective study. We analyzed patients with rhabdoid kidney tumor in the Department of Urological Surgery of the National Cancer Institute (Instituto Nacional de Enfermedades Neoplasicas: INEN) in Lima-Peru, from January 2000 to December 2019. The results: 10 cases were reported with anatomopathological diagnosis of Rhabdoid kidney tumor.
According to clinical characteristics: Seven male patients (70%) and three females (30%), the proportion of population related to age group was: Seven infants (between 1 to 23 months) (70%), two preschool (between 24 to 71 months) (20%), one child (between 6 to 12 years) (10%). About symptoms six patients present hematuria (60%), three patients with palpable tumor mass (30%) and one patient with fever (10%). Paraneoplastic hypercalcemia was infrequent with two cases (20%). According to surgical characteristics: Left kidney was the most frequent presentation in six cases (60%). Average tumor size was 10 cm. Of the ten patients, surgical treatment was made in nine patients (90%), of which seven (70%) had primary surgery, two (20%) had surgery post neoadjuvant treatment and one case did not have surgical treatment (due to progressive disease). R0 in seven cases (70%) and R1 in two cases (20%). Related to multimodal treatment, at the chemotherapy arm, eight patients (80%) received systemic chemotherapy; three of them (30%) had neoadjuvant therapy, two of them had complementary surgery (of these two patients, one had complementary adjuvant chemotherapy and the other one surgical management post neoadjuvant treatment without adjuvant treatment); the other one patient did not have surgical management in relation of progressive disease. The remaining five patients (50%) had adjuvant treatment posterior primary surgical management. One patient had adjuvant
radiotherapy (10%) and one patient (10%) had surgical management without complementary treatment. Prevalent clinical stage was III in five cases (50%), and medial global survival of seven months.
Conclusion: This entity is predominantly in young children, most of cases with advanced stage disease and poor survival even if the diagnosis is on early stage.
