Cardiovascular comorbidities for prediction of progression-free survival in patients with metastatic renal cell carcinoma treated with sorafenib.

ABSTRACT

BACKGROUND/AIMS: The purpose of the present study was to determine the relationship between iatrogenic arterial hypertension or baseline cardiovascular comorbidities and outcomes in metastatic renal cell cancer (mRCC) patients treated with sorafenib. METHODS: The study included 148 mRCC patients treated with sorafenib, 63 patients (43%) had preexisting hypertension, 18 patients (12%) coronary artery disease, and 15 patients (10%) mild heart failure. Resting blood pressure (BP) was monitored by clinic and home measurements. Sorafenib-induced hypertension was defined as systolic BP ≥140 and/or diastolic BP ≥90 mm Hg during the first month of treatment. RESULTS: Preexisting cardiovascular comorbidities were not associated with worsening prognosis of patients with mRCC treated with sorafenib. During the first month of treatment, sorafenib-induced hypertension was diagnosed in 76 patients (51.4%), and these patients had a significantly longer PFS (p < 0.00001) and a significantly lower overall mortality risk (p = 0.038). Patients with preexisting and sorafenib-induced hypertension had the longest PFS (p < 0.00001). CONCLUSIONS: Sorafenib-induced hypertension is a positive predictive factor in mRCC patients treated with sorafenib, especially in patients with a history of hypertension.
