Investigational vertebroplasty safety and efficacy trial (INVEST): patient-reported outcomes through 1 year.

ABSTRACT: To evaluate 1-year outcomes of the Investigational Vertebroplasty Safety and Efficacy Trial (INVEST), a blinded, randomized, controlled trial to investigate the effectiveness of percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fractures.Patients were enrolled at 11 sites in the United States, the United Kingdom, and Australia by using an institutional review board-approved protocol and HIPAA compliance, and all patients provided written informed consent. Patients were randomized to undergo vertebroplasty or a control procedure. After 1 month, patients were allowed to cross over and undergo the alternate procedure. Coprimary outcomes were patient-reported function, measured with the modified Roland-Morris Disability Questionnaire (RDQ), and pain (on a scale of one to 10) at 1 year. Intention-to-treat (ITT) and as-treated (AT) analyses were used to compare outcomes.One hundred thirty-one participants (68 in the vertebroplasty group and 63 in the control group) were included in the analyses. Patients in both groups showed improvements in pain and function at 1 year. In ITT analyses, patients randomized to vertebroplasty did not differ from control subjects in terms of RDQ results (difference, 1.37 points; 95% confidence interval [CI]: -0.88, 3.62; P = .231) but reported lower levels of pain (difference, 1.02 points; 95% CI: 0.04, 2.01; P = .042). Eleven of 68 patients who underwent vertebroplasty (16%) and 38 of 63 control subjects (60%) crossed over and elected to undergo the alternate procedure (P < .001). In AT analyses, patients treated with vertebroplasty did not differ from control subjects in terms of RDQ results (difference, 0.66 points; 95% CI: -1.98, 3.30; P = .625) or pain (difference, 0.85 points; 95% CI: -0.35, 2.05; P = .166).Vertebroplasty may provide a modest reduction in pain at 1 year compared with a control procedure; however, no difference in functional disability was observed. Clinical trial registration no. NCT00068822.

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.
