Effective Reduction of Gastric Cancer Risk With Regular Use of Nonsteroidal Anti-Inflammatory Drugs in Helicobacter Pylori–Infected Patients

Purpose Nonsteroidal anti-inflammatory drugs (NSAIDs) play protective roles in gastric carcinogenesis. However, the interaction between NSAIDs and Helicobacter pylori (H pylori) infection and the number needed to treat to prevent gastric cancer remains unclear. Patients and Methods We conducted a nationwide retrospective cohort study based on data from the Taiwan National Health Insurance Database. Hospitalized patients with a primary diagnosis of peptic ulcer disease were selected. Overall, 52,161 patients were divided into non-NSAID user and regular NSAID user cohorts. Standardized incidence ratios (SIRs), cumulative incidences, and hazard ratios (HRs) were calculated. Results Patients with peptic ulcers who never used NSAIDs had higher risk of gastric cancer compared with the general population (SIR, 2.11; 95% CI, 2.07 to 2.15), but regular NSAID use conferred lower risk (SIR, 0.79; 95% CI, 0.77 to 0.81). The protective role of NSAID use was observed in patients with gastric ulcer, but not in patients with non–H pylori-associated duodenal ulcer. On multivariate analysis, regular NSAID use was an independent protective factor for gastric cancer development (HR, 0.79 for each incremental year; P < .001), especially in H pylori-associated patients (HR, 0.52 for each incremental year; P < .001). Among patients with H pylori-infected gastric ulcers, the NNT to prevent a gastric cancer was 50. Conclusion Regular NSAID use may be a feasible way to prevent gastric cancer, at least in patients with gastric ulcers, and especially in H pylori-infected subjects.

Impact of NSAIDs Prior Authorization Policy on Patients' QoL

BACKGROUND: In 1996, the West Virginia Medicaid program targeted nonsteroidal antiinflammatory drugs (NSAIDs) for prior authorization (PA) to ensure cost-effective and appropriate utilization. PA guidelines required that patients must have tried and failed treatment with 2 different classes of generic NSAIDs before a brand-name NSAID could be approved. OBJECTIVE: To evaluate the impact of the requirement of PA for branded NSAIDs on the health-related quality of life (HRQoL) of patients who are chronic users of NSAIDs. DESIGN: Pre- and postintervention quasiexperimental design was used for this study. The sample consisted of continuously eligible Medicaid recipients who were <65 years old and who were diagnosed with rheumatoid arthritis, osteoarthritis, spondylitis, or chronic pain syndromes. Data were collected through a mail survey using the abbreviated version of the Arthritis Impact Measurement Scales. RESULTS: A total of 181 (37.1%) completed surveys were received, 110 (39.2%) from the branded-NSAID user group and 71 (32.7%) from the generic-NSAID user group. Patients who were restricted to generic NSAIDs did not report deterioration in any of the HRQoL domains measured, including mobility, walking and bending, hand and finger function, self care, household activities, social activities, and tension. CONCLUSIONS: The requirement of PA for the use of branded NSAIDs did not compromise patients' HRQoL at 8 weeks follow-up.
