RESUMO
BACKGROUND: Real-world data regarding patient characteristics, adjuvant treatment patterns, and long-term survival outcomes are needed to better understand unmet needs among patients with completely resected early-stage non-small cell lung cancer (NSCLC). METHODS: Electronic medical records from the U.S.-based ConcertAI Patient360™ database were analyzed in patients with stage IB-IIIA NSCLC who underwent complete resection prior to March 1, 2016. Patients were followed until death or July 1, 2021. This study evaluated adjuvant chemotherapy use, and overall survival (OS) and real-world disease-free survival (rwDFS) outcomes using the Kaplan-Meier method. The correlation between OS and rwDFS was assessed using the Kendall rank test. Among patients who did not recur 5 years following surgery, landmark analyses of OS and rwDFS were conducted to understand the subsequent survival impact of remaining disease-free for at least 5 years. RESULTS: Data from 441 patients with completely resected stage IB-IIIA NSCLC were included. About 35% of patients received adjuvant chemotherapy post-resection. Median OS and rwDFS from resection were 83.1 months and 42.4 months, respectively. The 5-year OS and rwDFS rates were 65.7% and 42.1%, respectively. OS and rwDFS were positively correlated (Kendall rank correlation coefficient = 0.67; p < 0.0001). Among patients without recurrence within 5 years after resection, the subsequent 5-year OS and rwDFS survival rates were 52.9% and 36.6%, respectively. CONCLUSIONS: Use of adjuvant chemotherapy was low, and the overall 5-year OS rate remained low despite all patients having undergone complete resection. Patients who remained non-recurrent over time had favorable subsequent long-term survival.

Aim: Real-world data on outcomes for early-stage non-small-cell lung cancer (NSCLC) are needed to better understand the benefits of new therapies. Methods: In this retrospective study using the ConcertAI Patient360™ database, overall survival and healthcare resource utilization were compared among patients with recurrent and non-recurrent completely resected stage IB-IIIA NSCLC. Results: Recurrence was associated with a shorter median overall survival compared with non-recurrence (31.5 months vs 75.6 months, respectively), lower survival probability 5-years post-resection, and higher healthcare resource utilization. Patients with late recurrence had a longer restricted mean survival time versus patients with early recurrence. Conclusion: Results from this real-world study highlight the potential value of preventing or delaying recurrence in patients with early-stage NSCLC.
This study looked at how people with early-stage non-small-cell lung cancer did after surgery to completely remove the disease. It compared two groups of patients: those whose disease came back after surgery and those whose disease did not come back after surgery. The group of people whose disease came back after surgery did not live as long as those whose disease did not come back after surgery (31.5 months vs 75.6 months). Patients whose disease came back had a lower chance of living at least 5 years after surgery and they had more hospital visits and doctor's office visits. In addition, those whose disease came back within 1 year did not live as long as those whose disease came back between 1 and 5 years after surgery. Preventing or delaying the return of disease after surgery is important for improving the lives of patients with early-stage non-small-cell lung cancer.

PURPOSE: This study evaluated the relative improvements in mortality data capture of adding different external data to enriched electronic medical records (EMRs) for patients with melanoma. METHODS: An enriched EMR database, containing structured and unstructured data, was used to evaluate the incremental mortality data capture of the following external data sources: Social Security Administration (SSA), public obituary, and an administrative open-claims database for the claims data set. Overall survival (OS) was assessed for each data set and the composite data set using the Kaplan-Meier method. RESULTS: A total of 3,882 patients were included in the study. The enriched EMR data set identified 1,085 patients with a death record. The SSA data set identified 213 patients (73 unique when combined with enriched EMR) with a death record, while the obituary data set identified 1,127 patients (241 unique). The administrative claims data set identified 378 patients (73 unique) with a death record; however, all these unique patients were already accounted for in the combined SSA and obituary data set. The composite data set yielded a median OS of 13.39 years, about 4 years shorter than the enriched EMR data set alone (17.63 years). CONCLUSION: When the enriched EMR data set was augmented with one external data set, the obituary data set provided the most additional value, followed by claims, and then SSA. The augmentation of all the data sources had a significant impact on the OS results compared with enriched EMR alone.

Aim: The objective was to estimate the cost of care associated with two negative pressure wound therapy (NPWT) technologies used to treat patients admitted to the hospital with moderate-to-severe foot infections. Materials & methods: A decision tree simulation model was developed to estimate the hospital costs associated with two different NPWT technologies: Cardinal Health™ PRO (NPWT-C) and V.A.C. ULTA™ (NPWT-K). Clinical data were obtained from a previously completed single-site prospective trial. One-way and probabilistic sensitivity analyses were performed to gauge the robustness of the results. Results: The total expected per-patient costs were US$41,206 (SD: US$8,194) for NPWT-C and US$44,439 (SD: US$8,963) for NPWT-K. Conclusion: This study found that NPWT-C was expected to minimize the total costs over the episode of treatment. Larger and more clinically diverse studies are recommended to confirm these findings.
