Angiotensin II receptor blockers and oral squamous cell carcinoma survival: A propensity-score-matched cohort study.

ABSTRACT:

Objectives

Angiotensin II receptor blockers (ARBs) improve the survival rates of patients with various cancers. However, it remains unclear whether ARBs confer a survival benefit on patients with oral squamous cell carcinoma (OSCC). Here, we assessed the associations between ARB use and survival in patients with OSCC of different stages.

Materials and methods

This was a 10-year retrospective cohort study of OSCC patients. We enrolled 7,558 patients diagnosed with oral cancer between January 2007 and December 2017 whose details had been entered into the Chang Gung Research Database. Seven hundred and fourteen patients were recruited from the Chang Gung Research Database after performing 1:1 propensity score-matching between ARB users and non-users. Cox's regression models with adjusted covariates were employed to detect factors influencing the survival rates of patients with OSCC.

Results

Kaplan-Meier analysis revealed that the overall survival (OS) rate of 180-day ARB users increased (p = 0.038). Cox's regression models indicated that ARB use, younger patients, early-stage OSCC, and patients without diabetes mellitus were independently prognostic of improved OS. Increased OS was more prominent in 180-day ARB users in stage III, Iva, and IVb categories.

Conclusions

ARB use for more than 180 days is associated with an increased survival rate and is a positive, independent prognostic factor in patients with OSCC. A further two-arm study should be conducted to confirm the clinical usefulness of ARBs in OSCC patients.

Project description:BackgroundAt present, the primary treatment of esophageal cancer is surgery-based comprehensive treatment, including adjuvant therapy such as chemotherapy and/or radiotherapy. However, the role of adjuvant therapy for esophageal squamous cell carcinoma (ESCC) with pathologically node-negative (pN0) disease is controversial. This study aimed to evaluate the impact of postoperative adjuvant therapy on survival in patients with pN0 ESCC.MethodsPatients with ESCC who underwent R0 esophagectomy in the Department of Thoracic Surgery of Sichuan Cancer Hospital from January 2008 to December 2013 were enrolled. Patients were divided into two groups: a surgery alone (Group S) group or a surgery + adjuvant therapy (Group S + A) group. The primary outcomes were overall survival (OS) and disease-free survival (DFS), and every consecutive case was followed up until death or the last follow-up.ResultsA total of 387 patients with ESCC patients who had pN0 were enrolled in the study. After propensity score matching (PSM), each group consisted of 150 patients. In the overall cohort, the 5-year OS (75.6% vs. 69.7%; P=0.004) and 5-year DFS (64.9% vs. 48.2%; P=0.003) rates were higher in Group S + A than in Group S. In the matched samples, the same outcomes were observed (5-year OS: 75.6% vs. 69.7%, P=0.026; 5-year DFS: 67.6% vs. 69.6%, P=0.036). Multivariate regression analysis indicated that postoperative chemotherapy was associated with longer OS [hazard ratio (HR): 0.622, 95% confidence interval (CI): 0.416-0.928; P=0.02] and DFS (HR: 0.571, 95% CI: 0.390-0.836; P=0.004); in contrast, T3 stage tumors (HR: 1.953, 95% CI: 1.238-3.082; P=0.004) and <15 lymph node dissections (HR: 1.81; 95% CI: 1.238-2.648; P = 0.002) were found to be independent risk factors for pN0 ESCC.ConclusionsAdjuvant therapy, especially chemotherapy, prolonged OS and DFS for patients with ESCC who had pN0 disease. Fewer lymph node dissections and T3 stage tumors were independent risk factors for OS and DFS.
