Genetic Testing for Li Fraumeni Syndrome AHS – M2081

Commercial Medical Policy
Origination: 01/2019
Last Review: 01/2019

Description of Procedure or Service

Li-Fraumeni syndrome is an autosomal dominant cancer predisposition syndrome characterized by a wide range of malignancies that appear at an unusually early age generally associated with defects in the tumor protein p53 gene (TP53) (Evans, 2017; Mai et al., 2016; Malkin, 2011).

***Note: This Medical Policy is complex and technical. For questions concerning the technical language and/or specific clinical indications for its use, please consult your physician.

Policy

BCBSNC will provide coverage genetic testing for Li-Fraumeni syndrome for when it is determined to be medically necessary because the medical criteria and guidelines shown below are met.

Benefits Application

This medical policy relates only to the services or supplies described herein. Please refer to the Member's Benefit Booklet for availability of benefits. Member's benefits may vary according to benefit design; therefore member benefit language should be reviewed before applying the terms of this medical policy.

When Genetic Testing for Li-Fraumeni Syndrome is covered

  1. Genetic counseling for Li-Fraumeni Syndrome genetic testing is considered medically necessary.
  2. Genetic testing for TP53 mutations is considered medically necessary to confirm a diagnosis of Li-Fraumeni syndrome under the following conditions:
    1. In a patient who meets either the classic or the Chompret clinical diagnostic criteria for Li-Fraumeni syndrome
      1. Classic LFS is defined by the presence of all of the following criteria:
        1.  A proband with a sarcoma before 45 years of age
        2. A first-degree relative with any cancer before 45 years of age
        3. A first- or second-degree relative with any cancer before 45 years of age or a sarcoma at any age
      2. Chompret clinical diagnostic criteria is defined by one of the following:
        1. Proband with tumor belonging to LFS tumor spectrum (e.g., soft tissue sarcoma, osteosarcoma, brain tumor, premenopausal breast cancer, adrenocortical carcinoma, leukemia, lung bronchoalveolar cancer) before age 46 years AND at least 1 first- or second-degree relative with LFS tumor (except breast cancer if proband has breast cancer) before age 56 years or with multiple tumors at any age; OR
        2. Proband with multiple tumors (except multiple breast tumors), 2 of which belong to LFS tumor spectrum and the first of which occurred before age 46 years; OR
        3. Patient with adrenocortical carcinoma (ACC) or choroid plexus tumor, at any age irrespective of family history
    2.  In women with early onset breast cancer (diagnosed at ≤30 years). The optimal strategy for confirming a TP53 mutation in a proband would be:
      1.  Sequencing of the entire TP53 coding region (exons 2-11). If sequencing is negative, then:
      2.  Deletion/duplication analysis
  3. Genetic testing for a TP53 mutation is considered medically necessary in a first, second or third degree relative of a proband with a known TP53 mutation (see Policy Guidelines No. 1). 
  4. Comprehensive genetic testing for a TP53 mutation (i.e. full sequencing of the genes and detection of large gene rearrangements) or multi-gene testing is considered medically necessary in a patient or, if unaffected, family member with highest likelihood of a mutation if there is no known familial TP53 mutation.

When Genetic Testing for Li-Fraumeni Syndrome is not covered

Genetic testing for a germline TP53 mutation is considered investigational.

Policy Guidelines

Policy Guideline #1:

At the present time, there are no specific, evidence-based, standardized guidelines for recommendations of which “at risk” relatives should be tested. In relatives of an index case, the risk of having a pathologic mutation, and developing disease, is influenced by numerous factors that should be considered in evaluating risk:

  1. Proximity of relation to index case (first-, second-, or third degree)
  2. Mode of inheritance of mutation (autosomal dominant versus autosomal recessive)
  3. Degree of penetrance of mutation (high, intermediate or low)
  4. Results of detailed pedigree analysis
  5. De novo mutation rate

If a proband has a TP53 mutation, the risk to the proband’s offspring of inheriting the mutation is 50 percent. If a proband has a TP53 mutation, the risk to other relatives may depend on the genetic status of the proband’s parents (that is, it is not a de novo mutation in the proband). Most TP53 mutations are inherited from 1 of a proband’s parents. After a mutation has been identified in a proband, the proband’s parent with any pertinent cancer history of family history should be tested first to establish the lineage of the mutation; otherwise, both parents should be tested. A family history could appear to be negative because of incomplete penetrance of the mutation, limited family members available for testing, early death of a parent, etc.

Literature Review

Li-Fraumeni syndrome is a rare cancer predisposition syndrome associated with germline mutation in the tumour suppressor gene TP53 on chromosome 17p13(Correa, 2016). It has an autosomal dominant pattern of inheritance with high penetrance. The human TP53 gene (chromosome 17p13.1) encodes for a ubiquitous transcription factor that is responsible for a complex set of critical regulatory functions that promote DNA repair and tumor suppression during episodes of cellular stress and DNA damage(Sorrell, Espenschied, Culver, & Weitzel, 2013). Most TP53 mutations are clustered in the DNA-binding domain within specific codons, such as 175 and 248(Villani et al., 2016). TP53 mutations are often missense alterations(Petitjean et al., 2007) that cause a change in one nucleotide and encode for a different amino acid than the one typically found in that particular location within the protein. Missense mutations are usually transcriptionally inactive leading to downstream events permissive for development of various malignancies throughout life; however, some reports have shown gain of function oncogenic effects in TP53 ( Brosh & Rotter, 2009; Sigal & Rotter, 2000).

These patients have a very high lifetime cumulative risk of developing malignancies and earlyonset malignancies. Around 50% of the individuals carrying mutations in TP53 will develop cancer by the age of 30 years(Hwang, Lozano, Amos, & Strong, 2003; Lustbader, Williams, Bondy, Strom, & Strong, 1992; Schneider, Zelley, Nichols, & Garber, 2013a), with a lifetime risk of up to 70% in men and almost 100% in women(Chompret et al., 2000). While many tumor types can be seen in patients with LFS, four cancers (breast, sarcoma, brain, and adrenocortical carcinoma) make up about 80% of LFS associated tumors (Gonzalez et al., 2009; Li et al., 1988; Lynch, Mulcahy, Harris, Guirgis, & Lynch, 1978; Olivier et al., 2003).

Breast Cancer accounts for about 25-30% of all LFS-associated tumors (Gonzalez et al., 2009; Olivier et al., 2003). Women with LFS-associated breast cancer tend to present at an earlier age (in the 20s or early 30s) with more advanced stage disease at the time of initial diagnosis.

Sarcomas account for another 25-30% of all LFS-associated tumor (Gonzalez et al., 2009; Ognjanovic, Olivier, Bergemann, & Hainaut, 2012; Olivier et al., 2003; Palmero, Achatz, AshtonProlla, Olivier, & Hainaut, 2010). Multiple types of soft tissue sarcomas and osteosarcoma are associated with LFS; but Ewing’s sarcoma, gastrointestinal stromal cell tumors (GIST), desmoids tumors, and angiosarcomas have not been reported in LFS (Olivier et al., 2003).

Brain Tumors occur in 9-16% of individuals with TP53 mutations (Gonzalez et al., 2009; Olivier et al., 2003; Palmero et al., 2010; Ruijs et al., 2010) Glioblastomas/astrocytomas are the most common but, medulloblastoma, ependymoma, supratentorial primitive neuroectodermal tumors, and choroid plexus tumors may also be seen (Farrell & Plotkin, 2007; Ruijs et al., 2010).

Adrenocortical Carcinoma (ACC) accounts for 10-14% of cancers in TP53 mutation carriers overall (Gonzalez et al., 2009; Palmero et al., 2010). While ACC has been diagnosed in individuals with LFS at a wide range of ages, it is considered a hallmark of LFS when diagnosed in childhood (Gonzalez et al., 2009; Herrmann et al., 2012; Palmero et al., 2010).

Other LFS Cancers

Beyond the four core LFS cancers, the next most frequently associated cancers include leukemia, lung, colorectal, skin, gastric, and ovarian (Gonzalez et al., 2009; Masciari et al., 2011; Olivier et al., 2003; Palmero et al., 2010; Walsh et al., 2011; Wong et al., 2006). All cancer types are diagnosed at younger than average ages.

LFS is characterized clinically by the development of cancers arising in multiple organ systems, often at a young age (Birch et al., 1998; Birch et al., 1994; Garber et al., 1991; Li et al., 1988; Mai et al., 2012; Malkin et al., 1990; Olivier, Hollstein, & Hainaut, 2010; Ruijs et al., 2010). The classic phenotype was clinically defined before the identification of germline mutations in TP53; these criteria are the most stringent and are the ones used to make a clinical diagnosis of LFS (with or without the identification of a deleterious germline TP53 mutation)(Li et al., 1988). Further studies revealed that, although highly specific for TP53 germline mutations, these criteria fail to include many mutation-positive families. Broader criteria were developed by Birch and Eeles to identify families which are Li-Fraumeni-like (LFL)(Birch et al., 1994; Eeles, 1995). The most robust analysis of TP53 mutation carriers to this date was performed in France by Bougeard et al., in developing the most recent version of the Chompret criteria to better identify families with milder phenotypes(Chompret et al., 2001; Gonzalez et al., 2009) shown to provide the highest positive predictive value and, when combined with the classic LFS criteria, provided the highest sensitivity for identifying individuals with LFS(Bougeard et al., 2008; Tinat et al., 2009).

Clinical criteriaDescription
Classical LFS (Li,
Fraumeni et al.,
1988)
I-sarcoma diagnosed in childhood/young adulthood (≤ 45 years) and
II-first-degree relative with any cancer in young adulthood (≤ 45 years) and
III-first- or second-degree relative with any cancer diagnosed in young adulthood (≤ 45 years) or sarcoma diagnosed at any age.

ACC: adrenocortical carcinoma; BC: breast cancer; CNS: central nervous system; LFS: LiFraumeni syndrome; LFL: Li-Fraumeni-like syndrome.

Siblings and offspring of the proband should be tested. If one of the proband’s parents carries the TP53mutation, each sibling has a 50% risk of having the mutation. If neither parent is found to carry the mutation, the risk to siblings is low, but they should be tested due to the possibility of germline mosaicism. Offspring of a proband have a 50% risk of carrying the mutation (Ballinger, Mitchell, & Thomas, 2015).Phenotypes of families carrying TP53 mutations can be highly variable (Malkin, 2011; McBride et al., 2014). Additionally, mutations in TP53 can lead to different consequences on gene function (McBride et al., 2014). The possibility of a second locus involved in LFS is an additional issue in the etiology of the syndrome, since approximately 20 % of LFS and up to 80 % of LFL families do not exhibit TP53 mutations (Malkin, 2011; McBride et al., 2014). However no association was found with p53 partners in tumor suppressor pathways, BAX(Barlow et al., 2004), CDKN2A(Portwine, Lees, Verselis, Li, & Malkin, 2000), TP63(Bougeard et al., 2001), CHEK2(Bougeard et al., 2001), BCL10(Stone et al., 1999), or PTEN(Brown, Sexsmith, & Malkin, 2000) in TP53-negative families. Although a few studies have linked other loci to LFL (Aury-Landas et al., 2013; Bachinski et al., 2005), TP53 remains the only gene conclusively associated to the syndrome.

Rana et al (2018) compared the personal and family cancer histories of TP53+ carriers who were identified though single gene testing (SGT) versus multi gene panel testing (MGPT). They found that “MGPT TP53+ individuals (n = 126) had an older median age at first cancer than SGT TP53+ carriers (n = 96; women: median = 36 vs 28 years, P < .001; and men: median = 40 vs 15 years, P = .004). The median age of breast cancer diagnosis was 40 years in MGPT TP53+ women vs 33 years in SGT TP53+ women (P < .001). In both cohorts, childhood and LFS core cancers, and for women, multiple primary cancers (not multiple breast tumors), were associated with TP53+ results. Established LFS testing criteria were less often met by MGPT TP53+ individuals.” They concluded that “MGPT TP53+ individuals differ in phenotype from those ascertained through SGT and are notably older at cancer diagnosis and less likely to meet LFS clinical criteria. These findings suggest that LFS may have a greater phenotypic spectrum than previously appreciated. This has implications for the counseling of MGPT TP53+ individuals. Prospective follow-up of these individuals and families is needed to re-evaluate cancer risks.”

Clinical Validity and Utility

According to Schneider et al (Schneider, Zelley, Nichols, & Garber, 2013b), approximately 80 percent of families with features of Li-Fraumeni Syndrome will have an identifiable TP53 mutation. Families that have clinical features of LFS without TP53 mutation are more likely to have a different hereditary cancer syndrome.

Some studies have reported that approximately 70% to 80% of families meeting the classic LiFraumeni syndrome criteria have TP53 mutation (Nagy, Sweet, & Eng, 2004; Varley, 2003). However, Gonzalez et al (Gonzalez et al., 2009) reported that a slightly lower positive predictive value for the classic criteria (56%), with high specificity but low sensitivity (40%). Chompret et al (Chompret et al., 2001)reported TP53 mutations can be found in 20% of cases using the Chompret criteria. Gonzalez et al (2009) reported a higher positive predictive value using Chompret criteria (35%).

Gonzalez et al (2009) used a clinical testing cohort to understand the spectrum of tumors associated with germline p53 mutations. Mutations were identified in 17% of patients submitted for testing. All families with a p53 mutation had at least one family member with a sarcoma, breast, brain, or adrenocortical carcinoma. When the classic Li-Fraumeni syndrome and Chompret criteria were used together, the testing sensitivity was 95% and the specificity was 52%.

Villani et al (Villani et al., 2011) assessed the feasibility and clinical impact of a comprehensive surveillance protocol in asymptomatic TP53 mutation carriers in families with Li-Fraumeni syndrome. 33 TP53 mutation carriers were identified, 18 of whom underwent surveillance. The authors reported a 3-year overall survival of 100% in the surveillance group compared to 21% in the non-surveillance group.

In 2016, Villani et al update their assessment of prospective observational study and modified the surveillance protocol. Out of the 89 carriers of TP53 pathogenic variants in 39 unrelated families, 40 (45%) agreed to surveillance and 49 (55%) declined surveillance. The authors reported a 5- year overall survival was 88·8% in the surveillance group and 59·6% in the non-surveillance group (Villani et al., 2016).

Mai et al (2017) determined the feasibility and efficacy of a comprehensive cancer screening regimen in Li-Fraumeni syndrome, using multiple radiologic techniques, including rapid wholebody magnetic resonance imaging (MRI) and laboratory measurements. They found that “Baseline cancer screening led to the diagnosis of cancer in 8 (6.9%) individuals (2 lung adenocarcinomas, 1 osteosarcoma, 1 sarcoma, 1 astrocytoma, 1 low-grade glioma, and 2 preinvasive breast cancers [ductal carcinoma in situ]); all but 1 required only resection for definitive treatment. A total of 40 (34.5%) participants required additional studies to further investigate abnormalities identified on screening, with 32 having incidental, benign, or normal findings, resulting in a false-positive rate of 29.6%. Non-MRI techniques, including baseline blood tests, abdominal ultrasonography in children, mammography, and colonoscopy, did not lead to a diagnosis of prevalent cancer.”

Federal Applicable Regulations

This test is considered a laboratory developed test (LDT); developed, validated and performed by individual laboratories.

LDTs are regulated by the Centers for Medicare and Medicaid (CMS) as high-complexity tests under the Clinical Laboratory Improvement Amendments of 1988 (CLIA’88).

As an LDT, the U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use.

Guidelines and Recommendations

Practice Guidelines and Position Statements

The National Comprehensive Cancer Network (NCCN) maintains guidelines for the diagnosis and management of Li-Fraumeni Syndrome (NCCN, 2018). NCCN recommends testing for Li-Fraumeni Syndrome in the following situations:

  • Individual from a family with a known TP53 mutation
  • Classic Li-Fraumeni syndrome criteria
  • Chompret criteria

The NCCN recommendations for management of Li-Fraumeni syndrome in adults include the following:

Breast cancer risk for women:

  • Breast awareness starting at age 18 years
  • Clinical breast exam every 6-12 months, starting at age 20 years
  • Breast screening:
    • Age 20-29 years, annual breast MRI screening with contrast
    • Age >30-75 years, breast MRI screening with contrast and mammogram with consideration of tomosynthesis
    • Age >75 years, management considered on an individual basis.
    • For women with a TP53 mutation, who are treated for breast cancer and who have not had a bilateral mastectomy, screening with annual breast MRI and mammogram should continue as described above
  • Discuss risk-reducing mastectomy and counsel regarding degree of protection, degree of age-specific cancer risk, reconstruction options, and competing risks of other cancers.
  • Address psychosocial, social, and quality-of-life aspects of risk-reducing mastectomy

Other cancer risks:

  • Comprehensive physical exam including neurologic examination with high index of suspicion for rare cancers and second malignancies in cancer survivors every 6-12 months.
  • Colonoscopy and upper endoscopy every 2-5 y starting at age 25 or 5y before the earliest known colon cancer in the family
  • Annual dermatologic evaluation starting at 18 y
  • Annual whole body MRI
  • Annual brain MRI may be performed as part of the whole body MRI or as a separate exam

Reproductive options:

  • For patients of reproductive age, advise about options for prenatal diagnosis and assisted reproduction including pre-implantation genetic diagnosis. Discussion should include known risks, limitations, and benefits of these technologies.

For relatives:

  • Advise about possible inherited cancer risk to relatives, options for risk assessment, and management
  • Recommend genetic counseling and consideration of genetic testing for at-risk relatives

Children:

  • Genetic testing is generally not recommended when results would not impact medical management.
  • For additional information on the management of children with LFA see Kratz C, Achatz M, BrugieresL et al. Cancer Screening Recommendations for Individuals with Li-Fraumeni Syndrome.
