Hereditary Cancer Panels: MYvantageTM, QvantageTM, and GIvantageTMTest code(s) 93768, 93792, 93791
Question 1. What are the benefits of multi-gene panels?
Multi-gene panels can identify patients with hereditary cancer predisposition through simultaneous analysis of a group of hereditary cancer predisposition genes when the personal and family histories do not clearly point to a specific cancer syndrome. Such panels can also identify patients with hereditary cancer predisposition when the clinical suspicion remains high despite a negative result on a single gene/syndrome genetic test. Use of a multi-gene panel can be a cost-effective, efficient approach to genetic testing.
Question 2. What is the cancer risk associated with a positive result (pathogenic or likely pathogenic mutation detected)?
The risk of cancer depends on which pathogenic/likely pathogenic variant is detected in a given gene. Each gene is placed into a risk category based on 2 criteria: 1) the highest relative risk for cancer conferred by the variant(s) in that gene, and 2) whether the variant(s) in the gene is a cause of a recognized genetic syndrome. Categories are defined as follows:
Question 3. What is included in the 3 panels?
This panel detects point mutations, deletions, and duplications in 34 genes: APC, ATM, BARD1, BMPR1A, BRCA1, BRCA2, BRIP1, CDH1, CDK4, CDKN2A (p14ARF and p16), CHEK2, EPCAM, MEN1, MLH1, MSH2, MSH6, MUTYH, NBN, NF1, PALB2, PMS2, POLD1, POLE, PTEN, RAD51C, RAD51D, RET, SDHB, SDHC, SDHD, SMAD4, STK11, TP53, and VHL. This includes genes in the high risk, moderate risk, and emerging risk categories.
This panel detects point mutations, deletions, and duplications in 14 genes: ATM, BRCA1, BRCA2, CDH1, CHEK2, EPCAM, MLH1, MSH2, MSH6, PALB2, PMS2, PTEN, STK11, and TP53. This includes genes in the high risk and moderate risk categories.
This panel detects point mutations, deletions, and duplications in 13 genes: APC, BMPR1A, CDH1, EPCAM, MLH1, MSH2, MSH6, MUTYH, PMS2, PTEN, SMAD4, STK11, and TP53. This includes genes in the high risk category.
Question 4. Who may be appropriate for these tests?
The following individuals may be appropriate for these tests:
- Individuals with a personal history of cancer who have tested negative for a single gene or syndrome, but whose personal or family history remains strongly suggestive of an inherited susceptibility
- Individuals with several different types of cancer in the family history that do not seem to fit a particular hereditary cancer syndrome
Informed consent following genetic counseling is strongly recommended.
Question 5. What guidelines can you give for choosing among the 3 panels?
There is a fair amount of overlap in the genes included in these panels. MYvantage, the largest panel, includes all of the genes in the other 2 panels. The following information may help you select among the 3:
- MYvantage includes 34 genes associated with a broad spectrum of hereditary cancers.
- Qvantage includes 14 genes predominantly associated with breast, colon, endometrial, and ovarian cancers.
- GIvantage includes 13 genes predominantly associated with gastrointestinal cancers.
Question 6. The gene mutation in my patient’s family is known. Is there a better test for my patient?
Yes. Please call Quest Genomics Client Services at 866-GENE-INFO to discuss this case with a genetic counselor and get help with selecting the most appropriate test.
Question 7. Who can I ask for help if I don’t know which test to order?
You can ask one of our genetic counselors. Please call Quest Genomics Client Services at 866-GENE-INFO to talk with a genetic counselor.
Question 8. When is the right time to test my patient?
The right time is different for every patient. A patient’s current medical status, personal experience with cancer, and general readiness for genetic information all influence the decision to be tested. Having an open dialogue with your patient about these topics can assist with shared decision making.
Question 9. My patient has a positive result. What does this mean?
Patients with a positive result (pathogenic or likely pathogenic mutation detected) have an increased risk for developing certain cancers relative to that in the general population.
The National Comprehensive Cancer Network (NCCN) provides up-to-date surveillance and management recommendations that can often be used, depending on the gene in question (https://www.nccn.org/professionals/physician_gls/f_guidelines.asp). Consider referring the patient to an oncology center experienced in treating patients with a hereditary predisposition to cancer. Such a center can discuss available options with the patient. These options may include increased surveillance, chemoprevention, and prophylactic surgery. Genetic counseling for family members is advised.
Question 10. My patient has a negative result. What does this mean?
A negative result means that pathogenic or likely pathogenic mutations were not found in the genes included in the panel. Implications of this result depend on the situation:
- Patient previously diagnosed with cancer: Your patient’s risk of recurrence or a related new cancer is based on his/her personal and family histories of cancer. In some instances, it may be appropriate to test for other hereditary forms of cancer. Please call Quest Genomics Client Services at 866-GENE-INFO to discuss possible additional studies with a genetic counselor.
- Patient not previously diagnosed with cancer, but with a family history of cancer: Testing an affected family member is recommended for proper risk assessment. Your patient’s risk of cancer is based on his/her personal and family histories of cancer. In some instances, it may be appropriate to test for other hereditary forms of cancer. Please call Quest Genomics Client Services at 866-GENE-INFO to discuss possible additional studies with a genetic counselor.
Question 11. My patient has a variant of unknown clinical significance (VUS). What does this mean?
A VUS result means that the variant has not been previously described in the literature or the clinical significance is unclear based upon currently available evidence. Medical management decisions should be based on personal and family history. Family studies may be indicated to better understand the clinical significance of this variant. If you have questions, please call Quest Genomics Client Services at 866-GENE-INFO to speak with a genetic counselor.
