e18506 Background: Inotuzumab Ozogamicin (InO), an anti-CD22 antibody-calicheamicin conjugate, has demonstrated superior clinical activity versus standard of care (SOC; intensive chemotherapy), including clinically meaningful improvement in overall survival (OS), high rates of complete remission (CR) and stem cell transplantation (SCT), and favorable patient-reported outcomes for R/R ALL in the phase 3 INO-VATE trial. Quality of life is an important consideration for R/R ALL patients in both short- and long-term survival. This study aimed to estimate mean overall survival adjusted for QoL (QALY) for patients treated with InO v SOC. Methods: A Markov model was developed with five health states - No CR, CR, post-SCT, progression, and death. Transition probabilities between health states and mortality rates were based on the InO-VATE trial. These rates were extrapolated to a lifetime horizon using parametric survival curves fitted to available OS data, and published literature for survival after SCT. Utilities (QoL valuations) for each health state were based on the patient-reported EQ-5D scores collected in the InO-VATE trial and a literature review. Adverse events experienced during and after treatments, including as a result of subsequent SCT, were taken into account in overall QoL. Outcomes were discounted at 1.5% and half-cycle corrected. Results: The estimated mean LY and QALY in each health state for InO and SOC and their differences are shown in Table. Most gains in LY and QALY for InO over SOC were from Post-SCT. Conclusions: This analysis taking into account both quantity and quality of life estimates InO offers an average of nearly 2 more years of QALY compared to SOC in R/R ALL, based on higher CR and SCT rates and better QOL. This is mainly driven by long-term gains of SCT. This can help inform patients, physicians and payers in decision making. [Table: see text]
involvement of more experienced residents was significantly associated with longer operative times across all increasing time intervals as compared to <2 hours (2 -<4 hours RRR 4.1, p¼0.007; 4 -<6 hours RRR 6.4, p¼0.001; >6 hours RRR 4.5, p¼0.024). Resident participation was not associated with LOS or 30-day readmissions, reoperations, or complications.CONCLUSIONS: Operative participation of a resident late in training in minimally invasive sacrocolpopexy results in a longer operative time. However, length of stay and all 30-day perioperative outcomes are not affected by resident involvement. For minimally invasive sacrocolpopexy, the educational benefit of surgical training does not adversely affect patient outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
