Risk of high-grade cervical dysplasia and cervical cancer in women with systemic inflammatory diseases: a population-based cohort study.

ABSTRACT: Previous studies have suggested a potential risk of cervical cancer in patients with systemic inflammatory diseases (SID) such as inflammatory bowel disease (IBD) and systemic lupus erythematosus (SLE).To assess the risk of high-grade cervical dysplasia, a surrogate endpoint for cervical cancer and cervical cancer, in women with SID, including IBD, psoriasis, rheumatoid arthritis (RA) or SLE, compared with the risk in women without SID.Using US insurance data (2001-2012), we conducted a cohort study of 133,333 women with SID, based on two or more diagnoses and one or more dispensed prescription for disease-specific treatment, and 533,332 women without SID. High-grade cervical dysplasia and cervical cancer was defined by a validated algorithm with a positive predictive value of ?81%.Over the mean follow-up of 2.1?years, the crude incidence rate of high-grade cervical dysplasia and cervical cancer per 100,000 person-years was the highest at 141.1 in SLE and the lowest at 82.2 in psoriasis among women with SID, and 73.4 in women without SID. The multivariable HR adjusted for potential confounders was 1.07 (95% CI 0.79 to 1.45) in IBD, 0.96 (95% CI 0.73 to 1.27) in psoriasis, 1.49 (95% CI 1.11 to 2.00) in RA and 1.53 (95% CI 1.07 to 2.19) in SLE. Multivariable HRs were increased, but not statistically significant, in IBD, RA and SLE with baseline use of systemic immunosuppressive drugs or steroids.The risk of high-grade cervical dysplasia and cervical cancer was 1.5 times higher in women with RA and SLE than in those without SID. The risk may be increased in IBD with use of systemic immunosuppressive drugs or steroids.

Project description:OBJECTIVE:Recent research showed an increased risk of high-grade cervical dysplasia and cervical cancer associated with rheumatoid arthritis (RA). The purpose of this study was to examine whether this risk was associated with the use of biologic versus nonbiologic disease-modifying antirheumatic drugs (DMARDs). METHODS:We identified RA patients in the US Medicaid and commercial insurance databases (for the years 2000-2012) who were starting treatment with either a biologic or a nonbiologic DMARD. High-grade cervical dysplasia or cervical cancer was identified with a validated claims-based algorithm, and we assessed utilization of gynecologic procedures. To control for potential confounders, those starting therapy with a biologic DMARD were matched 1:1 to those starting therapy with a nonbiologic DMARD according to the propensity score (PS). Hazard ratios (HRs) and rate ratios (RRs) in the PS-matched Medicaid and commercial insurance cohorts were pooled by an inverse variance-weighted fixed-effects model. RESULTS:We included 14,729 pairs of patients initiating biologic and nonbiologic DMARDs from the Medicaid cohort and 7,538 pairs from the commercial insurance cohort. During 73,389 person-years of active treatment with either biologic or nonbiologic DMARDs, 95 cases of high-grade cervical dysplasia or cervical cancer occurred in the 2 cohorts. The HR for high-grade cervical dysplasia or cervical cancer associated with biologic DMARD use was 1.25 (95% confidence interval [95% CI] 0.78-2.01) in the Medicaid cohort and 1.63 (95% CI 0.62-4.27) in the commercial insurance cohort, with a pooled HR of 1.32 (95% CI 0.86-2.01). The rate of gynecologic procedures involving the uterine cervix was not different between the 2 groups (pooled RR 0.96 [95% CI 0.90-1.02]). CONCLUSION:Among women with RA, initiation of therapy with a biologic DMARD was associated with a numerically significant, but not statistically significant, increase in the risk of high-grade cervical dysplasia or cervical cancer as compared to initiation of a nonbiologic DMARD.

Project description:BackgroundThe progression rate and predictors of anal dysplastic lesions to squamous cell carcinoma of the anus remain unclear. Characterizing these parameters may help refine anal cancer screening guidelines.ObjectiveThis study aimed to determine the rate of progression of high-grade anal dysplasia to invasive carcinoma in HIV-infected persons.DesignUsing the Surveillance, Epidemiology, and End Results database linked to Medicare claims from 2000 to 2011, we identified HIV-infected subjects with incident anal intraepithelial neoplasia III. To estimate the rate of progression of anal intraepithelial neoplasia III to invasive cancer, we calculated the cumulative incidence of anal cancer in this cohort. We then fitted Poisson models to evaluate the potential risk factors for incident anal cancer.SettingsThis is a population-based study.PatientsIncluded were 592 HIV-infected subjects with incident anal intraepithelial neoplasia III.Main outcome measuresThe primary outcome measured was incident squamous cell carcinoma of the anus.ResultsStudy subjects were largely male (95%) with a median age of 45.7 years. Within the median follow-up period of 69 months, 33 subjects progressed to anal cancer. The incidence of anal cancer was 1.2% (95% CI, 0.7%-2.5%) and 5.7% (95% CI, 4.0%-8.1%) at 1 and 5 years, following a diagnosis of anal intraepithelial neoplasia III. Risk of progression did not differ by anal intraepithelial neoplasia III treatment status. On unadjusted analysis, black race (p = 0.02) and a history of anogenital condylomata (p = 0.03) were associated with an increased risk of anal cancer incidence, whereas prior anal cytology screening was associated with a decreased risk (p = 0.04).LimitationsThe identification of some incident cancer episodes used surrogate measures.ConclusionsIn our population-based cohort of HIV-infected subjects with long-term follow-up, the risk of progression from anal intraepithelial neoplasia III to anal squamous cell carcinoma was higher than reported in other studies and was not associated with the receipt of anal intraepithelial neoplasia III treatment.
