Abstract
A total of 96 cases of renal carcinoma with distant metastasis at the time of diagnosis was studied. The patients were classified into 4 groups: Group O (16) in whom nephrectomy was not performed, Group A (51) who died due to carcinoma within 1 year of nephrectomy, Group B (25) who died due to carcinoma 1 to 3 years after nephrectomy, and Group C (4) who survived for 3 years or more after nephrectomy. Six clinical measurements were evaluated: haemoglobin, ESR, alpha 2 globulin, temperature, weight and C reactive protein. In addition, performance status, the number of organs with metastases, number of metastatic lesions and tumour growth rate were measured. The results showed that in patients surviving for 1 year or more after nephrectomy, there was an abnormality in the results of 3 or less of the 6 clinical measurements, performance was 0 or 1, and the carcinoma had metastasised to only one organ. In addition, it was found that the growth of metastatic lesions in patients who survived for 3 years or more was much slower than in the other patients. Nephrectomy was found to be effective in only 27% of our cases and we consider that careful deliberation should be made pre-operatively as to whether nephrectomy is really necessary in patients with metastasis. The decision should be made on the basis of the results obtained in the 6 clinical measurements given above.
