Because of the relative rarity of this tumor, all patients with clear cell sarcoma of the kidney should be considered for entry into a clinical trial. Treatment planning by a multidisciplinary team of cancer specialists (pediatric surgeon or pediatric urologist, pediatric radiation oncologist, and pediatric oncologist) with experience treating renal tumors is required to determine and implement optimum treatment.
Cancer prevention is action taken to lower the chance of getting cancer. By preventing cancer, the number of new cases of cancer in a group or population is lowered. Hopefully, this will lower the number of deaths caused by cancer.
To prevent new cancers from starting, scientists look at risk factors and protective factors. Anything that increases your chance of developing cancer is called a cancer risk factor; anything that decreases your chance of developing cancer is called a cancer protective...
The approach for treating clear cell sarcoma of the kidney is different from Wilms tumor since the OS of children with clear cell sarcoma of the kidney remains lower than for patients with favorable histology Wilms tumor. In the National Wilms Tumor Study-3 (NWTS-3), the addition of doxorubicin to the combination of vincristine, dactinomycin, and radiation therapy resulted in an improvement in disease-free survival for patients with clear cell sarcoma of the kidney. The National Wilms Tumor Study-4 (NWTS-4) showed that patients treated with vincristine, doxorubicin, and dactinomycin for 15 months had an improved relapse-free survival compared with patients treated for 6 months (88% vs. 61% at 8 years). In the National Wilms Tumor Study-5 (COG-Q9401) trial, children with stages I to IV clear cell sarcoma of the kidney were treated with a new chemotherapeutic regimen combining vincristine, doxorubicin, cyclophosphamide, and etoposide in an attempt to further improve the survival of these high-risk groups. All patients received radiation therapy to the tumor bed. With this treatment, the 5-year EFS was approximately 79% and OS was approximately 89%. Stage I patients had 100% 5-year EFS and OS. Stage II patients had a 5-year EFS of approximately 87% and OS of approximately 97%. Stage III patients had an approximately 74% 5-year EFS and an approximately 87% 5-year OS. Stage IV patients had a 5-year EFS of approximately 36% and 5-year OS of 45%. Clear cell sarcoma of the kidney has been characterized by late relapses; however, in NWTS-5, most relapses occurred within 3 years. In NWTS-5, the most common site of recurrence was the brain, which has been successfully treated with combination chemotherapy, surgery, and radiation therapy.[Level of evidence: 2A]
