New Assay Predicts NSCLC Chemo Benefit

Biomarker Testing Revolutionizes Early-Stage Lung Cancer Treatment

In a major breakthrough, new research reveals that biomarker testing is dramatically improving outcomes for patients with early-stage nonsquamous non-small cell lung cancer (NSCLC). the study, presented at the American Society of Clinical Oncology (ASCO), demonstrates that identifying adn treating patients who benefit from chemotherapy after surgery – even when conventional guidelines wouldn’t suggest it – significantly reduces the risk of disease recurrence.

Landmark Study Shows 78% Reduction in Cancer Recurrence

the AIM-HIGH study (NCT01817192) showed a remarkable 78% reduction in disease recurrence among patients who received chemotherapy guided by biomarker testing, compared to those who didn’t. This highlights the increasing importance of precision medicine in tailoring treatments to individual patient needs.

David Spigel, Md, Chief Scientific officer At Sarah Cannon Research Institute, presented the findings, emphasizing how a 14-gene molecular assay was used to identify high-risk patients with stage IA-IIA NSCLC who would benefit from adjuvant chemotherapy.

“Adjuvant therapy,although used commonly in the treatment of non-small cell lung cancer,is not recommended for stage IA disease,and is often deferred in stages IB and stage II,” Spigel explained. Molecular testing offers a way to identify patients with high-risk features beyond what is visible in the tumor.

Unprecedented Disease-Free Survival Rates

The results were striking: at 24 months, disease-free survival (DFS) was 96% (95% CI, 0.92-1.00) for those who received adjuvant chemotherapy, compared to 79% (95% CI, 0.70-0.90) in the observation group. The median DFS was not reached in either arm.

“This Is The First Prospective, Randomized Trial To Show Improvement In DFS With A molecular-Risk Discriminator In Stage IA Through Stage IIA Nonsquamous Non-small Cell Lung Cancer,” Spigel stated. he added that using this 14-gene assay to pinpoint who should have adjuvant therapy “May Substantially Reduce Rates Of Early Recurrence And Death.”

Lung cancer remains the deadliest cancer in the U.S., with an estimated 238,340 new cases and 127,070 deaths projected for 2024. This breakthrough offers new hope for improving survival rates,especially since screening is leading to earlier detection.

The National cancer Institute estimates that approximately 70,000 of these new cases are diagnosed as stage I or II NSCLC, with about 70% being nonsquamous.

Clinicians consider factors like cancer stage and tumor size to determine the best course of action after surgery. However, with 5-year DFS rates hovering around 65%, better methods were needed to identify patients who would benefit from additional treatment.

Biomarker testing provides a crucial tool for identifying these patients, revealing changes in genes, proteins, and other markers that indicate higher risk.

Study Methodology and Results

The AIM-HIGH study utilized RiskReveal, a 14-gene expression profile, to identify patients at stage IA-IIA with nonsquamous NSCLC who could benefit from adjuvant therapy. Of the 194 patients evaluable in the interim analysis, 87 were randomized to receive therapy, and 107 were placed in an observation group.

After a median follow-up of approximately 19 months,the hazard ratio for disease recurrence or death in the chemotherapy arm was 0.22 (95% CI, 0.06-0.76; P = .0087), demonstrating a important benefit from adjuvant chemotherapy.

Charu agrawal, Md, Leslye M. Heisler Professor Of Lung Cancer Excellence At Penn Medicine, agreed that there is a need to find patients who aren’t receiving adjuvant therapy, “yet we know that they are high risk.”

“These Early Interim Results From This Very Promising, Prospective Randomized Study Will Help Us lay The Foundation For Precision Therapy In Early-Stage Non-Small Cell Lung Cancer,” She said, adding that along with traditional assays, clinicians would have help from artificial intelligence solutions to better stratify patients.

“In The Future, we May Even Be Able To Add Personalized Vaccines After We Identify High-Risk Disease,” Agrawal Concluded.

The Future of Lung Cancer Treatment

The integration of biomarker testing represents a significant step toward personalized medicine in lung cancer treatment. By identifying specific genetic and molecular characteristics of a patient’s tumor, oncologists can tailor treatment plans to maximize effectiveness and minimize needless side effects.

According to a Lung Cancer Research Foundation report in December 2023, ongoing research is exploring new biomarkers and refining existing assays to further improve the accuracy and predictive power of these tests.

This personalized approach extends beyond chemotherapy, possibly paving the way for targeted therapies and even personalized vaccines designed to address the unique characteristics of each patient’s cancer.

Did You Know? Liquid biopsies, a type of biomarker testing, can detect cancer-related material in a blood sample, offering a less invasive way to monitor treatment response and detect recurrence.
