Abstract:
Background:Several studies suggested that hypertension is positively related to cancer incidence and mortality. In this study, we investigated the association between perioperative blood pressure (BP) and long?term survival out?comes in patients with rectal cancer. Methods:This study included a cohort of 358 patients with stages I–III rectal cancer who underwent a curative resection between June 2007 and June 2011. Both pre? and postoperative BPs were measured, by which patients were grouped (low BP: <120/80mmHg; high BP:≥120/80mmHg). The survival outcomes were compared between these two groups. The primary endpoints were disease?free survival (DFS) and cancer?speciifc survival (CSS). Results:Univariate analysis showed that patients with high preoperative systolic BP had lower 3?year DFS (67.2% vs. 82.1%,P=0.041) and CSS rates (81.9% vs. 94.8%,P=0.003) than patients with low preoperative systolic BP, and the associations remained signiifcant in the Cox multivariate analysis, with the adjusted hazard ratios equal to 1.97 [95%conifdence interval (CI)=1.08–3.60,P=0.028] and 2.85 (95% CI=1.00–8.25,P=0.050), respectively. Similarly, in postoperative evaluation, patients with high systolic BP had signiifcantly lower 3?year CSS rates than those with low systolic BP (78.3% vs. 88.9%,P=0.032) in univariate analysis. Moreover, high pre? and/or postoperative systolic BP presented as risk factors for CSS in the subgroups of patients who did not have a history of hypertension, with and/or without perioperative administration of antihypertensive drugs. Conclusions:High preoperative systolic BP was an independent risk factor for both CSS and DFS rates, and high postoperative systolic BP was signiifcantly associated with a low CSS rate in rectal cancer patients. Additionally, our results suggest that rectal cancer patients may get survival beneift from BP control in perioperative care. However, further studies should be conducted to determine the association between BP and CSS and targets of BP control.
