Hypertension in long-term survivors of childhood renal cancers.
The prevalence of hypertension was investigated in 119 adults who have survived for up to 53 years following the diagnosis of renal cancer in childhood (Wilms' tumor, 116 patients; renal carcinoma, three patients). Twenty-four (20%) have developed definite or borderline hypertension, as compared with 18.1 cases expected based on US population rates (relative risk [RR], 1.3; 95% confidence interval [CI], 0.9 to 2.0; P = .20). This nonsignificant excess is due to the heightened prevalence of definite hypertension among one subgroup of male patients. The findings are not explained by cigarette smoking, obesity, age, and stage at diagnosis of Wilms' tumor, or family history of hypertension. A case-comparison analysis within the cohort showed no consistent hypertensive effect associated with radiation therapy dose, radiotherapy concurrent with dactinomycin chemotherapy, or extent of renal surgery. Hypertension is not a common late complication of Wilms' tumor in our patients.
