Next-generation sequencing (NGS) offers actionable insights in cancer care, but patient access to therapies remains a challenge. Clinicians also use NGS guidance for unapproved treatments or clinical trials.
Area of Science:
- Genomic Medicine
- Oncology
- Clinical Decision-Making
Background:
- Next-generation sequencing (NGS) is increasingly utilized due to advances in genomic techniques.
- Evaluating the impact of NGS on clinical treatment decisions is crucial.
Purpose of the Study:
- To assess the extent to which next-generation sequencing (NGS) guides cancer treatment decisions.
- To identify challenges in accessing therapies based on NGS results.
Main Methods:
- A survey was distributed to American Society of Clinical Oncology (ASCO) members to assess NGS use and outcomes.
- Statistical analyses included Wilcoxon two-sample, chi-square, and Fisher's exact tests.
Main Results:
- Over half of respondents found NGS provided actionable information. NGS use varied by cancer type, highest in lung and gastric cancers.
- A third of clinicians faced challenges accessing FDA-approved therapies for actionable molecular variants.
- NGS results influenced decisions to pursue compassionate use, clinical trials, or off-label treatments.
Conclusions:
- Clinicians encounter significant barriers in accessing approved therapies for actionable NGS findings.
- The perceived impact of NGS influences clinical behaviors, including the pursuit of unapproved or off-label treatments and clinical trial enrollment.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
