Information
- WILMS' TUMOR (NEPHROBLASTOMA)
- Introduction: Wilms' tumor, a malignant tumor of the kidney, is the most common form of renal cancer in children. Peak incidence occurs at 3 years of age, with a slightly higher incidence in boys than girls. Ninety percent of the cases occur unilaterally; the treatment of choice is nephrectomy (and adrenalectomy) followed by chemotherapy and radiation.
- Assessment:
- Most common sign: abdominal mass (firm, nontender).
- Most often first found by parent changing diaper; felt as a mass over the kidney area.
- Intravenous pyelogram (IVP), abdominal ultrasound, and CT confirm the diagnosis.
- Metastasis occurs most frequently to the lungs: pain in chest, cough, dyspnea.
- Analysis/nursing diagnosis: altered urinary elimination (other diagnoses depend on stage of tumor and presence of metastasissimilar to adult with cancer).
- Nursing care plan/implementation:
- Goal: promote normal urinary function.
- Inform family that surgery is scheduled as soon as possible after confirmed diagnosis (within 2448 hours).
- Explain to family that the preferred surgical approach is nephrectomy (and adrenalectomy).
- Preoperative: do not palpate abdomen because the tumor is highly friable, and palpation increases the risk of metastasis.
- Postoperative nursing care: similar to care of adult with nephrectomy (see Chapter 6. Physiological Integrity).
Postoperative care also includes long-term radiation therapy and chemotherapy (actinomycin D, vincristine, Adriamycin; see Chapter 6. Physiological Integrity and Chapter 8. Physiological Integrity).
- Goal: discharge teaching to prepare parents to care for child at home.
- Teach parents need for long-term follow-up care with specialists: oncologist, urologist.
- Answer questions regarding prognosis, offering realistic hope.
- Children with localized tumor: 90% survival rate.
- Children with metastasis: 50% survival rate.
- Evaluation/outcome criteria:
- Child is able to maintain normal urinary elimination.
- Parents verbalize their understanding of home care for the child.
