Natl Acad. Recently, with the identification of new targetable drivers and the emergence of effective targeted therapies, broadly applying comprehensive genomic profiling in the clinical care for advanced NSCLC in lieu of the routine testing for classic drivers has been advocated [1, 3,4,5]. Further, a high tumor mutation burden (TMB) serves as a biomarker of the tumor response to PD-1/PD-L1 targeted-immunotherapy15,16. The sponsors had no role in the design and conduct of the study; collection, management, analysis, and interpretation of the data; preparation, review, or approval of the manuscript; and decision to submit the manuscript for publication. The log fold-change in the expression level of each gene between the epithelial and sarcomatoid components was evaluated using the Wald test, and differences with q<0.05 indicate a significant difference.

How clinically useful is comprehensive genomic profiling for patients with non-small cell lung cancer? b KaplanMeier analysis of RFS of 25 patients according to the average RNA level of each gene demonstrated that strong expression of four genes was associated with shorter RFS (p<0.05).

Nevertheless, the clinical implication of this practice, especially its impact on patient outcomes, remains unknown in advanced NSCLC. https://doi.org/10.1200/PO.17.00011:PO.17.00011. Patients carrying two or more actionable alterations were classified based on the alteration with the highest actionability level. Total RNA was isolated from 12 fresh-frozen tissue samples of 12 patients using RNA-Bee (Tel-Test, Gainesville, FL, USA) and purified using an RNeasy Mini Kit (Qiagen). Onc. Clin Cancer Res.

Pulmonary pleomorphic carcinoma (PPC) is a rare subtype of non-small cell lung cancer (NSCLC) that accounts for 0.41.6% of malignant lung tumors1,2. Nat. Rev. When we used IHC to determine the levels of PD-L1 among 56 FFPE specimens compared with those of CD274 mRNA from the RNA-seq dataset, we found a significant correlation with the latter (Pearson correlation coefficient r=0.63; p<0.001) (Fig. Nov 12, 2021 Matthew Gavidia A discussion at the National Comprehensive Cancer Network 2021 Virtual Congress: Biomarkers in Solid Tumors addressed the advantages and considerations for broad. https://doi.org/10.1186/s12916-021-02089-z, DOI: https://doi.org/10.1186/s12916-021-02089-z. Overall, comprehensive genomic profiling led to a matched targeted therapy in 37.7% (440/1166) of patients and a matched clinical trial enrollment in 20.9% (244/1166) of patients. Comprehensive genomic profiling was prospectively applied in 1564 advanced NSCLC patients to identify potentially actionable genomic alterations. In contrast, high expression of the other 11 genes correlated with longer RFS (Supplementary Fig. c Average numbers of nonsynonymous mutations in primary and metastatic tumors, revealing more in metastatic tumors relative to primary tumors. 366, 24432454 (2012). 2017;(1):116.

However, for patients with level 34 alterations as their highest actionable targets, no marked clinical advantage was observed with the investigational or off-label use of genotype-matched targeted therapies. Forty-nine patients underwent surgical resection, and 44 (90%) underwent lobectomy. PubMed Central Moreover, the private alterations in ASPM and ARID2, whose functions are to regulate the cell cycle31,32, may partly explain the enrichment of a gene set related to the cell cycle in the sarcomatoid component.

Potentially actionable alterations were detected in 781 patients (67.0%). b Gene Set Enrichment Analysis revealed that the SHEDDEN_LUNG_CANCER_POOR_SURVIVAL_A6 set was significantly enriched in the sarcomatoid group, whereas the SHEDDEN_LUNG_CANCER_GOOD_SURVIVAL_A4 set was enriched in the epithelial group. FASEB J. J. Med. 34, 794802 (2016). This percentage was comparable with the Caucasian population, where previous studies reported a 64% and an 86.9%, respectively [20, 21]. Among patients with potentially actionable alterations identified by comprehensive genomic profiling, 244 patients were enrolled into associated trials testing a matched targeted therapy, 196 received a matched targeted therapy off trial, and 215 received a nonmatched therapy (Fig. In the meantime, to ensure continued support, we are displaying the site without styles 2019; 25:5015-5026.

India while may harbour one third of world new lung cancer case, the understanding of comprehensive molecular landscape of lung cancer in India is poor. The study is summarized in Supplementary Fig. M.N., S.K. With regard to the timing of genomic profiling, we noticed that matched targeted therapies directed by frontline genomic profiling demonstrated a greater impact on extending PFS (HR = 0.26 [95% CI, 0.170.39], P < 0.001) and OS (HR = 0.09 [95% CI, 0.060.15], P < 0.001) compared with the genomic profiling-directed targeted therapies in subsequent lines of treatment (PFS: HR = 0.54 [95% CI, 0.450.66], P < 0.001; OS: HR = 0.30 [95% CI, 0.230.37], P < 0.001). A research team at Taipei Veterans General Hospital (VGH-TPE), led by Chi-Cheng Huang, MD, PhD, has shown that comprehensive genomic profiling (CGP) can yield valuable information to help treat triple-negative breast cancer patients.

Comprehensive genomic profiling of small cell lung cancer in Chinese patients and the implications for therapeutic potential In this study, we characterized the genomic alterations profile of Chinese SCLC patients. From October 2016 to October 2019, comprehensive genomic profiling was applied to a total of 1564 patients (2094 samples). For patients carrying two or more actionable alterations, the decision was made according to the alteration with the highest actionability level. Surg. Mutations within members of the RAS gene family were particularly frequent (16/49, 33%), suggesting that therapies targeting the RAS pathway may be effective for PPC.

Secondly, limited by the drug approval status and innovative drug availability in China, the latest FDA-approved drugs targeting alterations in BRAF, MET, RET, and NTRK were not available to most patients in this study. Nevertheless, no PFS or OS improvement was observed with the use of a genomic profiling-directed targeted therapy in patients carrying level 34 alterations compared with a nonmatched therapy (PFS 4.7months vs 4.6months, log-rank P = 0.530; Cox model HR = 0.86 [95% CI, 0.541.37], P = 0.533; OS 1.9years vs 2.4years, log-rank P = 0.238; Cox model HR = 1.35 [95% CI, 0.822.20], P = 0.240; Fig. 1a). These data suggest the utility of comprehensive genomic profiling in increasing patient access to targeted treatments and facilitating clinical development of innovative drugs targeting less common oncogenic drivers [1]. T.U., S.K., A.U., T.H. Using the cut-off thresholds 1% and 50%, according to previous studies20,21, we found that the level of CD274 mRNA was significantly upregulated in the high PD-L1 expression group (50%) (p<0.05, Fig. Mol. and H.M. developed the methodology. 24, 619633 (2018).

Meanwhile, the proportion of never smokers in our cohort was also higher than the usual NSCLC patient population [22], reflecting that patients with less tobacco exposure might be more likely and more willing to use comprehensive genomic profiling. Tumor genomic profiles were established in 1968 samples from 1166 patients (74.6%, Fig. Clin. d Individual mutations detected in primary and metastatic tumors.

In contrast to the intratumoral heterogeneity in PD-L1 expression, we found that both components had similar TMBs, and thus a TMB score in a portion of a tumor likely represents the TMB of the entire tumor.

Correspondence to P values were deemed statistically significant at two-sided P <0.05. High expression of CAPN14, LIN7A, LNX1, or PDGFRA significantly correlated with shorter RFS (p<0.05, Fig. 5g). Notably, several alterations occur only in the metastatic tumors of PPC, which may be acquired during disease progression.

The median primary lesion diameter was 4.6cm (range, 1.510.3cm). Many PPCs comprise an admixture of sarcomatoid (spindle or giant cell elements or both) and epithelial components (adenocarcinoma, squamous cell carcinoma, or undifferentiated NSCLC).
