Genomic Testing

Discussing How to Bring Next-Generation Sequencing to Community Practices

June 01, 2020

Jennifer Marie Suga, MD, discusses implementing a genomic oncology program at Kaiser Permanente Northern California through large-scale genomic next generation sequencing testing of patients with advanced cancers in the community setting.

Peripheral Biomarker of Response to Immunotherapy Emerges

March 17, 2020

In an interview with Targeted Oncology, Carl Morrison, MD, DVM, senior vice president Roswell Park Comprehensive Cancer Center, discussed the rationale for evaluating the Ion Torrent-based approach to predicting response to immunotherapy. He highlighted the importance of this in the clinical setting and advances are necessary to further validate this as a biomarker of response.

ESMO Collaborative Group Sets Standard for Defining MSI and Implementing Testing

March 11, 2020

Microsatellite instability has been an FDA-indicated biomarker for immunotherapy since 2017, when the PD-1 inhibitor pembrolizumab was approved for patients with solid tumors found to be mismatch repair deficient or MSI high. Other approvals since then, such as for the combination of ipilimumab and nivolumab in patients with MSI-H/dMMR metastatic colorectal can­cer, have established the relevance of cancer thera­pies for tumors with this biomarker specifically rather than tumor histology alone.

Role of Genetic Testing Expands for Both Patients and Providers in Oncology

March 10, 2020

In an interview with Targeted Oncology, Whitney Ducaine, MGC, CGC, CN-BM, discussed the evolution of genetic testing in oncology. She highlighted the importance of having conversations with genetic counselors to help inform the patient on their familial risks as well to help inform treatment decisions.

Molecular Testing Recommendations for NSCLC

March 06, 2020

Julie R. Brahmer, MD, discusses the role of molecular testing for patients with lung cancer and why this is particularly important for those with early-stage disease.

Liquid Biopsy Predicts Clinical Response Based on Mutational Volume in mNSCLC

February 28, 2020

High volumes of mutations observed through liquid biopsies may be associated with an improvement in progression-free survival and clinical benefit after first-line standard-of-care pembrolizumab-based therapy in patients with metastatic non-small cell lung cancer, according to findings from a prospective biomarker trial conducted by investigators at the University of Pennsylvania Perelman School of Medicine and Abramson Cancer Center, which were published in Clinical Cancer Research.

Genetic Profiling Suggests Rationale for Limited Response to Immunotherapy in Osteosarcoma

February 22, 2020

Treatment with immune checkpoint inhibitors appears to elicit limited clinical activity in patients with osteosarcoma. In a study, investigators at MD Anderson Cancer Center found that certain factors like poor infiltration of the tumor by immune cells, low activity from available T cells, a lack of immune-stimulating neoantigens, and multiple immune-suppressing pathways may interfere with response to immunotherapy in these patients, according to a press release from the organization.

Predictive Value of Select Gene Mutations Demonstrated in Phase III CLL Study

February 11, 2020

Next-generation sequencing in patients with chronic lymphocytic leukemia treated with the combination of chlorambucil and ofatumumab showed that the presence of TP53, SF3B1, and NOTCH1 mutations were predictive of reduced efficacy, according to the results of the phase III COMPLEMENT1 trial published in Haematologica.

Detecting the MET Exon 14 Skipping Mutations in NSCLC

January 16, 2020

Willemina R. Geurts-Giele, PhD, discusses 2 approaches used to detect the MET exon 14 skipping mutation in patients with non-small cell lung cancer.

Ion Torrent Oncomine Myeloid Research Assay Reduces Turnaround Time to 1 Day

January 08, 2020

The Ion Torrent Oncomine Myeloid Research Assay, the first fully-integrated next-generation sequencing platform, will be available in 2020 on the new Ion Torrent Genexus System for research use, according to a press release from Thermo Fisher Scientific. The platform features automated workflow to allow for result delivery within a single day, requiring minimal user intervention and tissue sample input.
