Regional Market Competition and the Use of Immediate Breast Reconstruction After Mastectomy.

ABSTRACT:

Background

Prior work has shown that the competitiveness of the market in which hospitals operate is associated with use of surgical procedures. This study examined the association between regional market competition and use of breast reconstruction for women with breast cancer and ductal carcinoma in situ undergoing mastectomy.

Methods

Women who underwent mastectomy from 2010 to 2011 recorded in the National Inpatient Sample were selected. The competitive market environment for each hospital in which patients were treated was estimated using the Herfindahl-Hirschman Index. Multivariable models were developed to examine the association between regional market competition and breast reconstruction, with adjustment for other clinical, demographic, and structural variables.

Results

Immediate breast reconstruction was performed for 9902 (45%) of 22,011 women. The rate of immediate breast reconstruction was 34.5% at hospitals in non-competitive markets, 49% at hospitals in moderately competitive markets, and 56.4% at hospitals in highly competitive markets (P < 0.0001). In a multivariable model, women in moderately competitive markets were 24% (risk ratio [RR] 1.24; 95% confidence interval [CI] 1.10-1.41) more likely to undergo immediate breast reconstruction than women in noncompetitive markets, whereas those in competitive markets were 25% (RR 1.25; 95% CI 1.11-1.41) more likely to have reconstruction. Later year of treatment, higher census tract income level, and residence in an urban area were associated with an increased likelihood of reconstruction (P < 0.05 for all). In contrast, older age, non-white race, and non-commercial insurance were associated with a lower likelihood of reconstruction (P < 0.05 for all).

Conclusion

Patients who undergo mastectomy at hospitals in competitive markets are more likely to undergo immediate breast reconstruction.

Project description:IntroductionThis study compares the perioperative results, aesthetic outcome and oncologic safety of single-port insufflation endoscopic nipple-sparing subcutaneous mastectomy combined with immediate reconstruction using prosthesis implantation (SIE-NSM-IRPI) with those of conventional open-nipple and areola-sparing subcutaneous mastectomy combined with immediate reconstruction using prosthesis implantation (C-NSM-IRPI).MethodsIn this retrospective cohort study, 64 early-stage breast cancer patients were divided into SIE-NSM-IRPI (n = 38) and C-NSM-IRPI (n = 26) groups. Perioperative results (operation time, intraoperative blood loss, incision length, drainage duration, and recent complications) were then compared between the two groups. Differences in satisfaction with the breasts, psychosocial well-being, physical well-being (chest) and sexual well-being were analyzed according to the BREAST-Q scale, and survival outcomes were also compared.ResultsThe median follow-up time was 51.5 months. The incision length of SIE-NSM-IRPI was shorter than that of C-NSM-IRPI (P < 0.001). SIE-NSM-IRPI achieved the same detection rate and median number of sentinel lymph nodes as C-NSM-IRPI (3.00vs. 4.00, P = 0.780). The incidence of prosthesis removal due to infection or prosthesis exposure in the SIE-NSM-IRPI group was lower than that in the C-NSM-IRPI group (P = 0.015). Satisfaction with breasts (82.00vs.59.00, P < 0.001), psychosocial well-being (93.00vs.77.00, P = 0.001) and physical well-being (chest) (89.00vs.82.00, P < 0.001) scores were higher in the SIE-NSM-IRPI group. There were no significant differences between the two groups in disease-free survival (hazard ratio = 0.829, 95% confidence interval = 0.182-3.779) and overall survival (hazard ratio = 1.919, 95% confidence interval = 0.169-21.842).ConclusionIn this selected cohort of patients with early breast cancer, SIE-NSM-IRPI was comparable to C-NSM-IRPI, considering oncologic safety and detection of sentinel lymph nodes. It had a lower incidence of prosthesis removal, shorter incision length, and was associated with better patient satisfaction with the breasts. More random clinical trials of this novel approach in a larger cohort of Chinese patients with an extended follow-up period are needed in the future.

Project description:Purpose The goals of immediate postmastectomy breast reconstruction are to minimize deformity and optimize quality of life as perceived by patients. We prospectively evaluated patient-reported outcomes (PROs) in women undergoing immediate implant-based or autologous reconstruction. Methods Women undergoing immediate postmastectomy reconstruction for invasive cancer and/or carcinoma in situ were enrolled at 11 sites. Women underwent implant-based or autologous tissue reconstruction. Patients completed the BREAST-Q, a condition-specific PRO measure for breast surgery patients, and Patient-Reported Outcomes Measurement Information System-29, a generic PRO measure, before and 1 year after surgery. Mean changes in PRO scores were summarized. Mixed-effects regression models were used to compare PRO scores across procedure types. Results In total, 1,632 patients (n = 1,139 implant, n = 493 autologous) were included; 1,183 (72.5%) responded to 1-year questionnaires. After analysis was controlled for baseline values, patients who underwent autologous reconstruction had greater satisfaction with their breasts than those who underwent implant-based reconstruction (difference, 6.3; P < .001), greater sexual well-being (difference, 4.5; P = .003), and greater psychosocial well-being (difference, 3.7; P = .02) at 1 year. Patients in the autologous reconstruction group had improved satisfaction with breasts (difference, 8.0; P = .002) and psychosocial well-being (difference, 4.6; P = .047) compared with preoperative baseline. Physical well-being of the chest was not fully restored in either the implant group (difference, -3.8; P = .001) or autologous group (-2.2; P = .04), nor was physical well-being of the abdomen in patients who underwent autologous reconstruction (-13.4; P < .001). Anxiety and depression were mitigated at 1 year in both groups. Compared with their baseline reports, patients who underwent implant reconstruction had decreased fatigue (difference, -1.4; P = .035), whereas patients who underwent autologous reconstruction had increased pain interference (difference, 2.0; P = .006). Conclusion At 1 year after mastectomy, patients who underwent autologous reconstruction were more satisfied with their breasts and had greater psychosocial and sexual well-being than those who underwent implant reconstruction. Although satisfaction with breasts was equal to or greater than baseline levels, physical well-being was not fully restored. This information can help patients better understand expected outcomes and may guide innovations to improve outcomes.
