title: [A clinical study of renal pelvic and ureteral cancer associated with bladder cancer].
abstract: We reviewed 45 cases of transitional cell carcinoma of the renal pelvis and ureter with reference to the coexistence or subsequent development of bladder cancer. Bladder cancer was associated with an upper urinary tract neoplasm in 26 of the 45 cases. The 5-year survival rate for coexistence of bladder cancer was 56% and that for subsequent bladder cancer was 65.6%. The 5-year survival rate for 19 cases unrelated with bladder cancer was 46.7%. Therefore, there was no significant difference among the three groups. As to degree of the malignancy of the renal pelvis and ureter, the 5-year survival rate was 73.7% for G1 and G2 and 26.2% for G3. As to the depth of invasion, of the renal pelvis and ureter the 5-year survival rate was 71.8% and 31.1% in the patients with stage of T1, T2 and T3, T4. The prognosis of cancer of the upper urinary tract depended on the degree of the malignancy, and the depth of invasion. Ninety two percent of subsequent bladder cancer was detected within 2 years after resection of the primary cancer.
