What is the typical post-surgical adjuvant therapy for Wilms tumor if the tumor extends beyond the renal capsule or has pulmonary metastases?

• A. Radiation therapy
• B. Antibiotics
• C. Immunotherapy
• D. Anticoagulation

Answer: (A)

In Wilms tumor, when the cancer extends beyond the kidney or there are lung metastases, adding radiation therapy after surgery is a standard way to achieve better local and regional control and to address microscopic disease that chemotherapy alone might miss. Radiation targets the area around the tumor bed to sterilize residual cancer cells in the abdomen, and in cases with pulmonary spread, whole-lung irradiation can be used in conjunction with multi-agent chemotherapy (typically including vincristine, actinomycin D, and doxorubicin). The other options—antibiotics, immunotherapy, or anticoagulation—do not address residual tumor cells or metastatic disease in this context.
