Official title: Genetic Testing Uptake Through an Enhanced Oncology Nurse-Led Intervention in Patients With Solid Tumors (GENESIS): A Pilot Study

Status Not yet recruiting

Clinical Trial Summary

Genetic factors are a significant determinant of the likelihood of developing various types of cancers. Identification of germline risk can have important implications for both patients and their families. Although estimates vary, pathogenic germline variants can be seen in ~3-17.5% of unselected patients with cancer with important clinical significance. Unfortunately, despite progress in multigene testing and the identification of heritable conditions, genetic counseling and testing (GCT) remains underutilized among cancer patients. Although there are multiple barriers to low testing, initial referral to GCT from the treating oncologist has been noted to be the most significant barrier.

Nurse navigation has been shown to improve the timeliness of cancer care and patient outcomes across various cancer types and improve the uptake of genomic testing in cancer patients. Despite proven benefits, community cancer centers often face resource limitations that prevent them from consistently assigning a dedicated nurse navigator to cancer patients. However, community centers universally have oncology nurses who routinely educate patients about their systemic therapies. By enhancing the "therapy education" sessions, the investigators hypothesize that oncology nurses can bridge this gap and potentially identify eligible patients, provide essential education on the importance of genetic testing, and facilitate the referral process. The investigators propose a pilot randomized study to evaluate the potential effectiveness, acceptability, and feasibility of a novel, nurse-led "enhanced education" intervention specifically designed to increase the uptake of GCT in adult cancer patients.

Clinical Trial Description

Identification of germline risk can have important implications for both patients and their families: it can help patients develop tailored cancer surveillance, risk-reducing measures, reproductive planning, identify novel genotype-directed drug targets, and also optimally address the risk of malignancy in at-risk relatives. Although estimates vary, pathogenic germline variants (PGV) can be seen in ~3-17.5% of unselected patients with cancer with important clinical significance. Although national and international guidelines such as the National Comprehensive Cancer Network (NCCN) outline the criteria for who should be offered genetic counseling and testing (GCT) based on a patient's personal and/or family history, recent studies have found that broader testing of at-risk patients might help identify PGV in patients who otherwise would not have met guidelines for genetic testing.

Unfortunately, despite progress in multigene testing and the identification of heritable conditions, GCT remains underutilized among cancer patients. A recent study revealed that the uptake of germline testing among cancer patients remains strikingly low; in California and Georgia, between 2013 and 2019, less than 7% of patients diagnosed with cancer underwent such testing. While a study indicates a promising recent increase in the use of germline testing among women diagnosed with breast and ovarian cancer from 2012 to 2019, there is still a significant gap in ensuring that all eligible patients are provided with GCT. Although there are multiple barriers to low testing, initial referral to GCT from the treating oncologist has been noted to be the most significant barrier.

Community cancer centers are crucial in providing accessible care to a large segment of the cancer patient population. However, community cancer centers often face various challenges with limited resources for specialized genetic services variability in community oncologists' practice patterns and perceptions in GCT, and potentially urban-rural variability in patient awareness and understanding of the potential impact of genetic testing on their care.

Nurse navigation has been shown to improve the timeliness of cancer care and patient outcomes across various cancer types, in addition to improving the uptake of genomic testing in cancer patients. Despite proven benefits, community cancer centers often face resource limitations that prevent them from consistently assigning a dedicated nurse navigator to cancer patients. However, community centers universally have oncology nurses who routinely educate patients about their systemic therapies. By enhancing the "therapy education" sessions, the investigators hypothesize that oncology nurses can bridge this gap and potentially identify eligible patients, provide essential education on the importance of genetic testing, and facilitate the referral process. This approach leverages the trust and communication between nurses and patients and the principle that informed patients are more likely to engage in their healthcare decisions to potentially overcome barriers to genetic testing uptake.

The investigators propose a pilot randomized study to evaluate the potential effectiveness, acceptability, and feasibility of a novel, nurse-led "enhanced education" intervention specifically designed to increase the uptake of GCT in adult cancer patients. Patients in the enhanced education arm will be scheduled for an enhanced therapy education session with a trained oncology nurse for patients starting or switching their systemic therapies. In addition to the education conducted as part of the usual care, the nurse will: 1) provide detailed education on GCT; and 2) if the patient is eligible and agreeable to GCT, order a referral to GCT (if not already ordered). Nurses will provide a "nudge" to the referral coordinators within a week of the education session to ensure the referral process is completed. ;
