206 patients underwent nephrectomy for renal cell carcinoma during the years, 18 of them were found to be a spindle cell type. The average patient age was 58.4 years (range 41 to 75 years).
Their symptoms included gross hematuria in 11 patients, palpable mass in 4, flank pain in 1, general fatigue in 1 and symptom related to skinmetastasis in 1. Of the tumors 13 were in the left kidney and 5 were in the right kidney.
Of the patients 4 had stage IV disease, 4 stage III, 3 stage II and 7 stage I.
Of 13 patients of spindle cell type 5 were found to have an angiographic hypovascular neoplasm.
The grade of spindle cell type tumors was generally high and showed a poorly demarcated margin. The survival rate 1, 3 and 5 years of the spindle cell type tumors were 54.3%, 47.5% and 38.0%, respectively. In particular, patients with spindle cell type alone all died within 1 year after operation.
