Objectives

Narrative objectives1

This trial is part of the third generation of clinical trials run by the JWiTS group. Wilms tumor (nephroblastoma) is the most common malignant renal neoplasm in children but the incidence is rare (approximately one by several ten thousands children per year). Therefore, 40-50 cases were registered to JWiTS a year. To identify the new effective regimen, nationwide clinical trials are needed. JWiTS was launched at 1996 and have performed JWiTS 1 and JWiTS 2 protocol studies. In these studies, multimodal therapy using actinomycin D, vincristine, and/or doxorubicin and radiation therapy was effective, and overall survival of the patients was improved to nearly 90 %. About 5-10 % of the Wilms tumors are arise bilaterally, and classified as stage V. In the previous studies, the survival of the bilateral cases was improved to around 90%. However in terms of renal preservation, nephrectomy was performed in two thirds of the patients. These results were not satisfactory, therefore new study protocol to improve the renal preservation is necessary to create.
In this protocol, chemotherapy is performed first without tumor biopsy to reduce the tumor size. After chemotherapy, nephron-sparing tumor resection will be performed. To identify the resectability, evaluation of the CT images after chemotherapy will be performed by the specialized JWiTS radiologists. The protocol study was opened in 2014, and national-wide multi-center clinical trial is now undergoing.

Interventions/Control_1

Chemotherapy regimen DD-4A using actinomycin D (ACD), vincristine (VCR) and are administered for 6 or 12 weeks.
ACD iv for 0.045 mg/kg on week 1, 7, 13, 19 and 25.
VCR iv for 0.05mg/kg is started at week 2 and continued every week.
DOX iv for 1.5mg/kg on Week 4 and 10, and 1.0mg/kg on week 16 and 22.
The tumor size is measured by image analysis at week 6 and 12.
If nephron sparing surgery is possible, the tumor will be completely resected and post-operative chemotherapy and/or radiotherapy will be performed according to the operational findings and pathological diagnosis.
