|
The first case of Wilms´ tumor was described by thomas rahce in 1814, and the classic paper regarding this type of tumor was-described by wilms in 1899.
Wilms´ tumor is the most common Abdomohial mass in childhood. And the majority of Patients with wilms´ tumor are first seen because of abdomohal mass. Every abdominal mass in an infant or child should be considered as malignant tumor until histologically proved otherwise.
The discovery of an abdominal mass necessitates. Immediate investigation of its nature. X-ray examination should be performed immediately.
A plain film of the, abdomen, an intravenous pyelogram, and a chest film are usually necessary for investigation. There are five methods oftherapy commonly used for the treatment of patients with wilms tumor. They are
1) Nephrectomy alone
2) Radiation alone
3) Preoperative roentgen therapy plus nephrectomy
4) Nephrectomy followed by postoperative roentgen therapy
5) Preoperative roentgen therapy followed by nephrectomy and subsepueht postoperative rdehtgeh therapy.
Early Radical nephrectomy is the basic method of therapy for wilms tumor. Conventional roentgen therapy can usually decrease the size of the tumor mass when used preoperatively and increase the survival rate significantly when used postooeratively.
The method of hephrectomy plus postoperative radiation has been the most popular one in recent years. Gross and heuhauser reported an over all 2-year survival rate of 47.3% in 38 patients treated by this method.
In 1955 collins proposed the prognostic criterion of a "period of risk" Following therapy. Application of this "period of risk" principle to each patient provides the most accurate evaluation of the prognosis.
