e13010 Background: Identification of oncogenic driver mutations (ODM) and targeted therapies have increased the number of treatment options for patients (pts) with non-squamous non-small cell lung cancer (ns-NSCLC). Different methods exist to detect ODM and there is no standard approach. This study examines the changes in detection of ODM over a 2-year period before and after implementing reflexive genomic testing using next generation sequencing (NGS) in January 2015. Methods: We retrospectively reviewed ns-NSCLC cases (stages I-IV) in 2014 and 2015 using the UVA Cancer Registry. We identified pts with pathologically-confirmed ns-NSCLC and reviewed any genotyping - single gene pyrosequencing, NGS, or FISH for gene rearrangements - within 90 days of pathologic confirmation. Comprehensive genomic profiling (CGP) was defined as both NGS and ALK/ROS1 FISH. Chi-square analyses were generated using SAS 9.4. Results: A total of 360 pts were included. 60% had genotyping while 19% underwent CGP. Mutations are summarized in the table below. From 2014 to 2015, genotyping increased from 50% to 69% (p<0.001), with CGP increasing from 2% to 48% of testing performed (p<0.001). Detection of oncogene driver mutations increased from 28% to 46% (p=0.009). Doubletons (pts with 2 driver mutations) increased from 0% to 5% (p=0.036). Conclusions: Reflexive CGP significantly increased the rate of detection of ODM at our center with results similar to previous studies. Previous studies detected low rates of doubleton mutations, perhaps due to lack of uniform NGS testing. Utilization of NGS may increase detection of doubleton mutations, for which further study is necessary to evaluate efficacy of targeted therapies. For centers without reflexive CGP, implementing this approach is likely to increase rates of ODM detection and expand treatment options. [Table: see text]

Oncology Treatment

Biliary tract cancers (BTCs) are poor prognosis malignancies with limited treatment options. Capecitabine has recently emerged as an effective agent in the adjuvant setting; however, treatment of advanced disease is still limited to first-line cisplatin and gemcitabine chemotherapy. Recent global efforts in genomic profiling and molecular subtyping of BTCs have uncovered a wealth of genomic aberrations which may carry prognostic significance and/or predict response to treatment, and several targeted agents have shown promising results in clinical trials. As such, the uptake of comprehensive genomic profiling for patients with BTCs and the expansion of basket trials to include these patients are growing. This review describes the currently approved systemic therapies for BTCs and provides insight into the emerging targeted and immunotherapeutic agents, as well as conventional chemotherapeutic regimes, currently being investigated in clinical trials.

e13668 Background: There are over 100 FDA approved targeted therapies across 15 cancer types, offering improved outcomes over existing therapies. However, many of these require genetic testing, for example, advanced non-small cell lung cancer (aNSCLC) patients have over 15 targeted therapies requiring a DNA-based test. Doing multiple tests can exhaust sample, while increasing cost and turn-around time. NGS panels, often with hundreds of genes, can address some of these issues. Here we asked across aNSCLC patients if the use of NGS panels has increased over the last 3 years in community oncology practices. Methods: The Integra Connect database, which includes electronic medical record (EMR) and claims data on over 1,000,000 US cancer patients, was queried across five community oncology practices to identify aNSCLC patients (stage IIIB or IV) treated between January 2017 and January 2020. Manual chart review abstracted tumor type, stage, treatment, and testing. Patients tested for all 7 NCCN recommended genes (EGFR, ALK, ROS1, BRAF, MET, RET, ERBB2) were grouped as “NGS Panel”, patients with less genes as “Single Gene/Small Panel”, and patients with no evidence of testing as “No Test”. A Chi-Square test was used to compare actionable results between patients with NGS panels versus small panels. Results: 1,007 aNSCLC patients were analyzed and showed a doubling of the use of broad-based NGS testing from 13% in 2017 to 26% in 2019 across over 100 oncologists (table). 23% of patients had actionable results when tested on broad-based panels versus 17% using single gene or small panels (p = .048). Targeted therapies were used in 17% of broad-based tested patients, versus 15% in patients tested for single genes or small panels. Conclusions: We see an uptake of broad-based NGS testing in community oncology, which can lead to more actionable results and better utilization of targeted therapies for those patients. However, this seems to be caused by providers shifting from small panels to large panels, rather than an overall increase in testing, as we do not see the percentage of untested patients decrease.

Comprehensive Genomic Profiling

Abstract Background With the identification of new targetable drivers and the recent emergence of novel targeted drugs, using comprehensive genomic profiling in lieu of the routine testing for classic drivers in the clinical care for advanced NSCLC has been increasingly advocated. However, the key assumption justifying this practice, that comprehensive genomic profiling could lead to effective anticancer therapies and improve patient outcomes, remains unproved. Methods Comprehensive genomic profiling was prospectively applied in 1564 advanced NSCLC patients to identify potentially actionable genomic alterations. Patients were assigned to genotype-matched targeted therapies or nonmatched therapies based on the profiling results. Its utility in directing treatments was determined by the proportion of patients receiving genotype-matched targeted therapies and the proportion of patients being enrolled into genotype-matched clinical trials. Its impacts on patient outcomes were assessed by comparing progression-free survival (PFS) and overall survival (OS) between patients who received a genotype-matched and nonmatched therapy. Results From October 2016 to October 2019, tumor genomic profiles were established in 1166 patients, leading to a matched targeted therapy in 37.7% (n = 440) and a genotype-matched trial enrollment in 20.9% of patients (n = 244). Potentially actionable alterations were detected in 781 patients (67.0%). For these patients, a genomic profiling-directed matched therapy significantly improved PFS (9.0 months vs 4.9 months, P < 0.001) and OS (3.9 years vs 2.5 years, P < 0.001) compared with a nonmatched therapy. Excluding patients with standard targeted therapies, genomic profiling led to a matched targeted therapy in 16.7% (n = 24) and a matched trial enrollment in 11.2% (n = 16) of patients. No PFS (4.7 months vs 4.6 months, P = 0.530) or OS (1.9 years vs 2.4 years, P = 0.238) benefit was observed with the use of genotype-matched targeted therapies in this population. Conclusions Comprehensive genomic profiling is of clinical utility in assisting treatment selection, facilitating clinical trial enrollment, and improving patient outcomes in advanced NSCLC. However, for patients carrying alterations without standard-of-care targeted drugs, the interpretation of genomic profiling results should be careful given the low likelihood of benefit from the investigational or off-label use of targeted therapies in this population in the current treatment landscape.

<p><strong>Objective.</strong> We report a female patient diagnosed with a leiomyosarcoma and who harbored a druggable target as identified by comprehensive genomic profiling in the course of clinical care.</p><p><strong>Case Report.</strong> The patient progressed five years after curative intent surgery and adjuvant treatment. After failure of multiple lines of chemotherapy,she was enrolled in a trial of an ALK inhibitor based on comprehensive genomic profiling (CGP) identifying an TNS1-ALK fusion.</p><p><strong>Conclusion. </strong>In this case, identification of the ALK kinase fusion permitted enrollment in a matched mechanism driven clinical trial after exhausting standard of care treatment options. CGP raises the possibility of uterine inflammatory myofibroblastic tumor as an alternative diagnosisto leiomyosarcoma, highlighting the complementary role of CGP beyond immunohistochemical analyses.</p>
