ABSTRACT

Aim: To describe real-world biomarker testing, treatment and survival in stage IA-IIIC non-small-cell lung cancer (NSCLC). Methods: Electronic records of USA-based patients in the CancerLinQ Discovery® database with stage IA-IIIC NSCLC (diagnosed between 2014 and 2018) were screened; a curated cohort of 14,452 records was identified for further analysis. Results: Of 3121 (21.6%) patients who had EGFR testing, 493 (15.8%) were EGFR-mutation positive. Of 974 patients who underwent surgical resection, 513 (52.7%) received adjuvant therapy. A quarter of patients with EGFR-mutation positive NSCLC received targeted adjuvant therapy. Conclusion: Approximately a fifth of patients underwent EGFR testing; biomarker testing is important to ensure optimal outcomes for patients with stage I-III NSCLC.


A study investigating how many patients with early-stage non-small-cell lung cancer (NSCLC) had mutations in a protein called EGFR and which treatments they received in routine clinical practice: The treatment recommended by medical experts for stage IA­IIIA non-small-cell lung cancer (NSCLC) is surgical removal of the growth (tumor). Patients with stage II or III, and some with stage IB disease, are recommended to receive treatment with medications such as chemotherapy or oral cancer treatments after surgery (adjuvant treatment). In some lung cancers, there are mutations in a protein called EGFR. Osimertinib, a drug that blocks the activity of mutated EGFR on cancer cells, reducing their growth and spread, is recommended as an adjuvant treatment for patients with EGFR-mutated, stage IB­IIIA NSCLC. This study aimed to understand how many patients with stage I­III NSCLC have tumors with EGFR mutations, and which treatments patients received in everyday clinical practice, before new medicines such as osimertinib (that treat EGFR-mutated NSCLC) were recommended. We looked at anonymous data from 14,452 patients with stage I­III NSCLC treated at cancer clinics in the USA between 2014 and 2018. We found that 3121 (21.6%) patients had an EGFR mutation test and 493 (15.8%) had EGFR-mutation positive NSCLC. Of patients who had surgery to remove the tumor, 55% received adjuvant therapy (treatment after surgery). It is important to perform EGFR mutation testing in patients with stage IB­IIIA NSCLC so that patients with EGFR-mutation positive NSCLC can receive appropriate treatment.

ABSTRACT

INTRODUCTION: Tyrosine kinase inhibitors and immune checkpoint inhibitors (ICIs), each requiring testing for precision biomarkers, have recently been approved in the adjuvant setting. We assessed the potential value of multigene testing in early lung adenocarcinoma (LUAD). METHODS: Using a real-world clinicogenomic database linking deidentified electronic health record-derived clinical data to genomic data, we selected patients with LUAD who underwent tissue comprehensive genomic profiling (CGP). Using a probabilistic decision tree, we estimated the cost implications of the avoidance of adjuvant ICI in patients with programmed death-ligand 1-positive (PD-L1+) LUAD and an ALK, ROS1 or RET driver. RESULTS: The CGP was performed on a specimen collected before advanced disease in 20% (1320 of 6697) of cases and ordered before advanced diagnosis for 12.6% (847 of 6697) of patients. The prevalence of driver alterations in early and advanced-stage specimens was similar, though KRAS mutations were enriched in early disease and drivers including ALK rearrangements in advanced disease. Patients who had CGP results obtained before versus after recurrence had less time between recurrence and the start of any first-line treatment (median 3.6 versus 6 wk, p < 0.001). Through avoidance of ICI in programmed death-ligand 1-positive early LUAD with an ALK, ROS1 or RET driver, we estimated that the universal CGP could reduce expected costs by $1597.23 per patient relative to EGFR single-gene testing. CONCLUSIONS: The CGP can identify driver alterations and accelerate the start of first-line therapy at recurrence. It may also represent a cost-effective approach for avoiding futile adjuvant ICI in patients with drivers that have historically lacked activity with ICI in metastatic disease.

ABSTRACT

Despite remarkable treatment advancements in patients with advanced non-small cell lung cancer (NSCLC), recurrence rates for those with resectable, early-stage disease remains high. Immune checkpoint inhibitors and targeted therapies are 2 promising treatment modalities that may improve survival outcomes for patients with resected NSCLC when moved from the advanced stage to the curable setting. There are many clinical studies that have evaluated or are currently evaluating immunotherapy or targeted therapy in the perioperative setting, and recent trials such as CheckMate 816, ADAURA, and IMpower010 have led to new approvals and demonstrated the promise of this approach. This review discusses recent and ongoing neoadjuvant and adjuvant systemic therapy trials in NSCLC, and where the field may be going in the near future.

ABSTRACT

Surgery is the best option for patients with early stage non-small cell lung cancer (NSCLC). However, the rate of local and metastatic recurrences following surgery alone is high, especially in NSCLC patients with N2 lymph node involvement. A recent American study showed that 60% of lung cancers are diagnosed in an advanced stage, and less than 20% are diagnosed in an early, resectable stage. The same study reported the 5 year survival of patients with stage IV NSCLC was 6% compared to 50% in patients with resectable NSCLC depending by stage. The addition of adjuvant or neoadjuvant chemotherapy only improves 5 year survival by 5%-10%. Recently, immunotherapy with or without chemotherapy and novel targeted therapies have yielded excellent results, in terms of both progression-free survival and overall survival, in advanced NSCLC. Published studies have shown a benefit in using immunotherapy and targeted therapy in both the adjuvant and neoadjuvant settings with many further studies still ongoing. Here we review the published data on immunotherapy and targeted therapy in the adjuvant and neoadjuvant settings in patients with operable NSCLC.
