Ultrasound in renal carcinoma: an essential in follow-up.
A total of 115 patients underwent radical nephrectomy for renal carcinoma in this hospital between 1983 and 1990. Follow-up was available in 113 cases (mean 27 months, range 0-93). The overall actuarial survival was 66% at 2 years and 53% at 5 years. Fifty-three patients have been followed up with annual abdominal ultrasound over the last 2 years. Abnormal ultrasound scans were reported in 6 patients (11%) on follow-up. Two had para-aortic lymph node recurrence amenable to further surgery. One patient developed a metachronous tumour and a partial nephrectomy was carried out. Three patients had local recurrence not amenable to further surgery. Ultrasound and computed tomography have found an invaluable place in the pre-operative diagnosis and staging of renal carcinoma. Sixteen of 113 tumours were diagnosed by ultrasound or intravenous urography carried out for some other purpose; 8 were less than 5 cm in diameter and 12 were T category N0M0V0. The 2-year survival rate in this group was 85% (mean 30 months, range 19-67). We consider the routine follow-up of renal carcinoma with clinical examination and annual chest X-ray to be inadequate. The application of ultrasound in the follow-up of these patients has provided a valuable adjunct to our clinical practice. It has allowed the prompt diagnosis of lymph node recurrence or metachronous tumour amenable to secondary surgery with the potential for improved survival in this group of patients. We consider this to be the logical extension of the value of ultrasound in the pre-operative diagnosis of renal carcinoma.
