This study investigates the real-world performance of immunotherapies in the treatment of patients with aNSCLC.
Immunotherapy-Treated Non-Small Cell Lung Cancer Patients With Sensitizing Gene Alterations: A Real World Survival Analysis
September 2021
Mutation-specific tyrosine kinase inhibitors (TKIs) have demonstrated efficacy among patients (pts) with advanced non-small cell lung cancer (aNSCLC) with sensitizing gene alterations (GA). It is unclear how effective immune checkpoint inhibitor (ICI) therapy is among NSCLC pts with sensitizing GA, particularly after TKI failure or resistance.
Customizable Natural Language Processing Biomarker Extraction Tool
August 2021
Natural language processing (NLP) in pathology reports to extract biomarker information is an ongoing area of research. MetaMap is a natural language processing tool developed and funded by the National Library of Medicine to map biomedical text to the Unified Medical Language System Metathesaurus by applying specific tags to clinically relevant terms. Although results are useful without additional postprocessing, these tags lack important contextual information.
Rapid real-world data analysis of patients with cancer, with and without COVID-19, across distinct health systems
May 2021
The understanding of the impact of COVID-19 in patients with cancer is evolving, with need for rapid analysis.
Genomic markers associated with hyperprogression in patients with lung cancer treated with immune checkpoint inhibitors
May 2021
Immune checkpoint inhibitor (ICI) therapy has become a mainstay of non-small cell lung cancer (NSCLC) treatment. However, not all patients (pts) benefit with a subset paradoxically experiencing accelerated tumor growth while on ICI. Hyperprogression (HP) refers to accelerated tumor growth on ICI with worsening clinical status. Various gene alterations may be associated with HP including MDM2/MDM4 amplifications, EGFR alterations, and STK11/LKB1 mutations. Kato et al. (doi: 10.1158/1078-0432.CCR-16-3133) showed HP in 6/6 pts with MDM2/MDM4 amplification and in 2/10 pts with EGFR alterations. This report describes HP in pts with NSCLC treated with ICIs in a large health system.
Evaluating real-world overall survival (rwOS) across oncology data sources: Friends of Cancer Research non-small cell lung cancer pilot study
May 2021
Friends of Cancer Research (FOCR), the United States Food and Drug Administration (FDA), ASCO and five data partners, including Syapse, used electronic health record-sourced datasets to conduct parallel analyses in RWD. The study assessed estimates of real-world overall survival among patients taking platinum doublet chemotherapy (chemo) or pembrolizumab in combination with chemo (IO+chemo) in first-line treatment for metastatic non-small cell lung cancer (mNSCLC). A range of observed results highlights the complexity of RWD, including differences in sample size, underlying patient variability across datasets, and missing covariate data. The harmonization process and observed results underscore the importance of a well-articulated research question and a pre-specified analytic plan to guide data harmonization, standardization, and analysis.
The real-word evidence of first-line treatment of pembrolizumab in advanced NSCLC
May 2021
For advanced NSCLC, evidence from clinical trials indicates the superiority of pembrolizumab (P) than chemotherapy (C) in PD-L1 positive patients and superiority of P+C than C among PD-L1 unselected patients. Meta-analysis from different clinical trials stated P+C failed to improve overall survival (OS) or progression-free survival (PFS) compared with P alone. This study, developed in partnership with Henry Ford Health System, used real-world data of PD-L1+ patients with advanced NSCLC to compare treatment effect of P with P+C, finding that, among patients with PD-L1+ advanced NSCLC, there is no significant difference in rwOS for patients with 1L treatment of P+C or P alone.
Feasibility of RECIST-based real-world tumor response assessment in metastatic non-small cell lung cancer patients
May 2021
Treatment response to anti-cancer therapies for advanced lung cancer is usually assessed according to the Response Evaluation Criteria in Solid Tumors (RECIST), which is not generally applied in real-world settings. With real-world evidence increasingly being used to support promising treatment, this study, developed in partnership with Advocate Aurora Health, evaluated the feasibility of assessing real-world lung cancer response by RECIST-based measurement of lesions on archived radiologic films and assessed its concordance with treatment response based on oncologist narratives in electronic health record (EHR). This study is an important step in demonstrating the potential to approximate real-world RECIST-based treatment response using EHR abstraction of oncologists’ documentation.
Myocarditis as a rare, yet serious adverse event associated with immune checkpoint inhibitors in patients with non-small cell lung cancer: Case series from a large community-based cancer center
May 2021
Patients (pts) with lung cancer and other cancers treated with immune checkpoint inhibitors (ICI) may experience immune related adverse events (irAE). These can present with variable severity and with single- or multi-organ involvement including pneumonitis, colitis, hepatitis, and myocarditis/pericarditis. The incidence of myocarditis has been reported between 0.06% and 2.4% and is associated with a high mortality (25% to 50%). This retrospective review of real-world data (RWD) investigates myocarditis as a high-grade adverse event in pts with lung cancer treated with ICIs.
Validation of a Mortality Composite Score in the Real-World Setting: Overcoming Source-Specific Disparities and Biases
April 2021
This study tested whether a composite mortality score could overcome gaps and potential biases in individual real-world mortality data sources. Complete and accurate mortality data are necessary to calculate important outcomes in oncology, including overall survival. However, in the United States, there is not a single complete and broadly applicable mortality data source. It is further likely that available data sources are biased in their coverage of sex, race, age, and socioeconomic status (SES).

This retrospective single-arm study described real-world treatment patterns and clinical outcomes of patients with hormone receptor–positive/human epidermal growth factor receptor 2–negative (HR+/HER2–) A/MBC who received PAL+AI as first-line (1L) therapy in US practices.
Considerations for Use of Real-World Evidence in Oncology
October 2020
Informed by several pilot projects leveraging a common protocol (established in the RWE 1.0 Pilot Project and expanded upon in subsequent pilots, described below) among multiple real-world data partners, US and international populations, and oncology-specific disease settings, Friends of Cancer Research (Friends) and collaborators identified implications of dataset specifics and patient characteristics on real-world endpoints and recommendations for developing a RWE framework to encourage and guide future RWE studies that leverage multiple data sources to answer a single question through a harmonized protocol.
Using Real-World Data (RWD) from an integrated platform for rapid analysis of patients with cancer with and without COVID-19 across distinct health systems
July 2020
Reports suggest worsened outcomes in patients with cancer and COVID-19, varying by geography and local peak dynamics. Cancer in patients diagnosed with COVID-19 associated with increased risk of severe events with even greater risk among patients with metastatic disease and those with recent treatment1 and higher incidence of COVID-19 reported among Black Americans.
Overall survival in high and very high PD-L1 expressing patients with advanced non-small cell lung cancer treated with immune checkpoint inhibitors in a real-world data setting
May 2020
Clinical trials show improved survival for advanced non-small cell lung cancer (aNSCLC) patients whose tumors are positive for PD-L1 expression when treated with immune checkpoint inhibitors (ICI), including pembrolizumab (Pb) and nivolumab (Nb). It is unclear whether relatively higher PD-L1 expression by tumor proportion score (TPS) is associated with better response to treatment, and whether this can be generalized to a real-world setting.
Outcomes in patients with advanced non-small cell lung cancer (aNSCLC) and high PD-L1 expression treated with immune checkpoint inhibitor monotherapy: An FDA-pooled analysis
May 2020
Higher PD-L1 score ≥ 50% predicts for greater benefit to immune checkpoint inhibitor (ICI) therapy in first line (1L) treatment of aNSCLC. It has recently been reported that PD-L1 score ≥ 90% predicts for even greater benefit to 1L ICI monotherapy (Aguilar et al., 2019). We examined pooled clinical trial databases to examine the relationship between high PD-L1 expression across multiple ICI monotherapies in 1L and second line (2L) treatment of aNSCLC.
Molecular alterations with hyperprogression in lung cancer patients treated with immune checkpoint inhibitors in a large health system
May 2020
Immune checkpoint inhibitor (ICI) therapy has become a mainstay of lung cancer treatment. However, not all NSCLC patients (pts) benefit, a subset paradoxically experiences accelerated tumor growth while on immunotherapy. Hyperprogression (HP) refers to accelerated tumor growth on ICI with worsening clinical status.
