Disparities in the Use of Breast-Conserving Therapy Among Patients With Early-Stage Breast Cancer.

ABSTRACT: Although breast-conserving therapy (BCT) is an accepted modality for treatment of early-stage breast cancer, many women continue to undergo mastectomy. Detailing the factors associated with choice of BCT may assist with overcoming barriers in the use of this treatment modality.To conduct a population-based examination of the factors that influence the use of BCT.Using the National Cancer Data Base, we examined the surgical choices of women with stage T1 or T2 breast cancer treated between 1998 and 2011. Logistic regression analysis conducted between September 19, 2013, and August 26, 2014, was used to assess the multivariate association between patient and facility variables and the probability of undergoing BCT.Factors associated with the use of BCT.A cohort of 727,927 women was identified in the National Cancer Data Base. Use of BCT, determined using odds ratio (OR) and 95% CI, was greater in patients aged 52 to 61 years compared with younger patients (1.14; 1.12-1.15) and in those with the highest educational level (1.16; 1.14-1.19). Rates of BCT were lower in patients without insurance compared with those with private insurance (0.75; 0.72-0.78) and in those with the lowest median income (0.92; 0.90-0.94). Academic cancer programs, US Northeast location, and residence within 27.8 km of a treatment facility were associated with greater BCT rates than were community cancer programs (1.13; 1.11-1.15), Southern location (1.50; 1.48-1.52), and residence farther from a treatment facility (1.25; 1.23-1.27). When comparing BCT use in 1998 with use in 2011, increases were seen across age groups (from 48.2% to 59.7%), in community cancer programs (48.4% in 1998 vs 58.8% in 2011), and in facilities located in the South (45.1% in 1998 vs 55.3% in 2011).Although the use of BCT has increased during the past 14 years, nonclinical factors, including socioeconomic demographics, insurance, and travel distance to the treatment facility, persist as key barriers to receipt of BCT. Interventions that address these barriers may facilitate further uptake of BCT.

Project description:IntroductionThis study examined the patterns of prolonged opioid use and the factors associated with higher risk of prolonged opioid use among opioid-naïve working-age patients with early-stage breast cancer.MethodsUsing MarketScan data, the study identified 23,440 opioid-naïve patients who received surgery for breast cancer between January 2000 and December 2014 and filled at least one opioid prescription attributable to surgery. Prolonged opioid use was defined as one or more prescriptions for opioids within 90 to 180 days after surgery and defined extra-prolonged opioid use as one or more opioid prescriptions between 181 and 365 days after surgery. Multivariable logistic regressions were performed to ascertain factors associated with prolonged and extra-prolonged use of opioids.FindingsOf the 23,440 patients, 4,233 (18%) had prolonged opioid use, and 2,052 (9%) had extra-prolonged opioid use. Patients who received mastectomy plus reconstruction had the highest rate of prolonged opioid use (38%) followed by mastectomy alone (15%). A multivariable logistic regression confirmed that patients with mastectomy and reconstruction had the highest odds ratio of prolonged opioid use compared to lumpectomy and whole breast irradiation (adjusted odds ratio, 5.6; 95% confidence interval, 5.1-6.1). Mean daily opioid dose was consistently high without any obvious dosage reduction among patients with opioid use.InterpretationThis large observational study showed a high rate of prolonged opioid use among patients who received surgery for early-stage breast cancer and found significant difference in prolonged opioid use by treatment type.Implications for practiceThis large observational study found a high rate of prolonged opioid use among working-age patients with early-stage breast cancer who received curative surgery, especially among patients who received mastectomy. Among patients with opioid use, the mean daily opioid dose was consistently high without any obvious dosage tapering. This study highlights the need to emphasize appropriate opioid therapy and potential dosage reduction or discontinuation among patients with early-stage breast cancer who received surgical interventions.
