Performance of Tumor Surveillance for Children With Cancer Predisposition. JAMA Oncol 2024; 10:1060-1067. [PMID: 38900420 PMCID: PMC11190829 DOI: 10.1001/jamaoncol.2024.1878] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Accepted: 03/14/2024] [Indexed: 06/21/2024]
Abstract
Importance Pediatric oncology patients are increasingly recognized as having an underlying cancer predisposition syndrome (CPS). Surveillance is often recommended to detect new tumors at their earliest and most curable stages. Data on the effectiveness and outcomes of surveillance for children with CPS are limited. Objective To evaluate the performance of surveillance across a wide spectrum of CPSs. Design, Setting, and Participants This cohort study reviewed surveillance outcomes for children and young adults from birth to age 23 years with a clinical and/or molecular CPS diagnosis from January 1, 2009, through September 31, 2021. Patients were monitored using standard surveillance regimens for their corresponding CPS at a specialty pediatric oncology center. Patients with hereditary retinoblastoma and bone marrow failure syndromes were excluded. Data were analyzed between August 1, 2021, and December 6, 2023. Exposure Cancer predisposition syndrome. Main Outcomes and Measures Outcomes of surveillance were reviewed to evaluate the incidence, spectrum, and clinical course of newly detected tumors. Surveillance modalities were classified for accuracy and assessed for common strengths and weaknesses. Results A total of 274 children and young adults (mean age, 8 years [range, birth to 23 years]; 144 female [52.6%]) with 35 different CPSs were included, with a median follow-up of 3 years (range, 1 month to 12 years). During the study period, 35 asymptomatic tumors were detected in 27 patients through surveillance (9.9% of the cohort), while 5 symptomatic tumors were detected in 5 patients (1.8% of the cohort) outside of surveillance, 2 of whom also had tumors detected through surveillance. Ten of the 35 tumors (28.6%) were identified on first surveillance imaging. Malignant solid and brain tumors identified through surveillance were more often localized (20 of 24 [83.3%]) than similar tumors detected before CPS diagnosis (71 of 125 [56.8%]; P < .001). Of the 24 tumors identified through surveillance and surgically resected, 17 (70.8%) had completely negative margins. When analyzed across all imaging modalities, the sensitivity (96.4%), specificity (99.6%), positive predictive value (94.3%), and negative predictive value (99.6%) of surveillance were high, with few false-positive (6 [0.4%]) or false-negative (5 [0.3%]) findings. Conclusions and Relevance These findings suggest that standardized surveillance enables early detection of new tumors across a wide spectrum of CPSs, allowing for complete surgical resection and successful treatment in the majority of patients.

Cancer Med 2021; 10:2026-2034. [PMID: 33624449 PMCID: PMC7957159 DOI: 10.1002/cam4.3787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Revised: 01/30/2021] [Accepted: 02/03/2021] [Indexed: 11/08/2022] Open
Abstract
Background With the advent of next generation sequencing, tumor and germline genomic testing are increasingly being used in the management of pediatric cancer patients. Despite this increase in testing, many pediatric hematology–oncology (PHO) providers are not confident interpreting or utilizing tumor or germline genomic results to care for their patients. Methods We developed and delivered a needs assessment survey to PHO program directors, attendings, and fellows in the United States to understand this deficiency, gather data on existing cancer genomics educational initiatives, and query preferences for creating a future curriculum. Results The survey includes 31 (41%) of 74 invited PHO program directors, 110 (11%) of 1032 invited attendings, and 79 fellows. The majority of attending physicians and fellows responding to the survey agree that understanding tumor (95% attending physicians; 95% fellows) and germline (86% attending physicians; 94% fellows) genomic information is essential for their practice. However, only 9 of 31 (29%) responding programs report that they have an existing cancer genomics curriculum. Most program directors indicated that the ideal genomics curriculum would occur during the first year of fellowship and incorporate direct patient care, online modules, and problem‐based learning. Attending physicians and fellows identified that addressing indications for ordering tumor and germline genomic testing, counseling about the risks and benefits of such testing, and interpreting and individualizing clinical management based on tumor and germline results should be included in a future curriculum. Conclusion The results of this study reveal a great need to develop a curriculum that can be offered across PHO fellowship programs to expand knowledge in the area of cancer genomics.

Cancer genetic counseling for childhood cancer predisposition is associated with improved levels of knowledge and high satisfaction in parents. J Genet Couns 2020; 30:710-719. [PMID: 33179831 DOI: 10.1002/jgc4.1357] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2020] [Revised: 10/05/2020] [Accepted: 10/06/2020] [Indexed: 12/28/2022]
Abstract
Previous surveys of adults with cancer have revealed increased levels of genetic knowledge, varying levels of worry, and high satisfaction with cancer genetic counseling. We sought to determine the impact of cancer genetic counseling on parental levels of genetic knowledge, worry about cancer, and satisfaction in the context of suspected cancer predisposition in a child. We hypothesized that parents would be satisfied with cancer genetic counseling and that cancer genetic counseling would improve baseline parental genetic knowledge and decrease levels of worry. Parents were recruited from a pediatric cancer predisposition clinic in the United States. A survey was administered to two cohorts: One cohort had received cancer genetic counseling in the past and only completed one survey (post-only, n = 26), and another cohort completed the survey before and after cancer genetic counseling (pre/post, n = 23). The survey included questions on demographics, knowledge of genetics, worry levels, and satisfaction with the cancer genetic counseling service. The post-genetic counseling survey also contained a free-text section for parents to indicate what they took away from the sessions. Parental levels of genetics knowledge increased by an average of 1.9 points (p = .01), with 65.2% of parents demonstrating an increase in genetics knowledge score. Average worry levels did not change significantly (p = .37), with 52.2% of parents indicating decreased worry, and 34.8% indicating increased worry. Overall, 91.8% of parents reported high levels of satisfaction. Our results show that cancer genetic counseling in a pediatric cancer predisposition clinic improves parental levels of genetics knowledge. Satisfaction rates suggest that parents find this service beneficial. These results demonstrate the positive impacts of cancer genetic counseling on parents of children in which a hereditary cancer syndrome is known or suspected.

Abstract
BACKGROUND Cancer predisposition syndromes (CPS) are caused by germline pathogenic variants that put an individual at increased risk of developing cancer throughout their lifetime. It is estimated that approximately 10-15% of children with cancer have an underlying CPS. Although research has investigated the clinical utility of genetic testing for children diagnosed with cancer, this study aimed to gain a deeper understanding of parental attitudes toward genetic testing in this population. PROCEDURE Attitudes toward genetic counseling and testing among parents of children diagnosed with cancer were solicited through questionnaires distributed to a pediatric cancer clinic and online support groups. Quantitative data were analyzed using descriptive statistics and chi-square tests for association. RESULTS The majority of participants had prior knowledge of genetic counseling (64.3%), yet most were not offered genetic counseling (59.5%). Fifty percent of parents reported interest in pursuing genetic counseling/testing and 31.0% reported uncertainty. Statistically significant associations were identified between interest in genetic counseling/testing and the child's age at diagnosis, child's sex, and participant annual income (P < .05). CONCLUSIONS Parents of children diagnosed with cancer generally expressed interest in genetic counseling/testing; however, notable uncertainty was also reported. In light of this uncertainty, genetic counselors have an ideal skill set to engage families in their decision-making process as they weigh the benefits and drawbacks to pursuing genetic testing among this population. Demonstrated parental receptiveness to genomic technologies supports expansion of genetics providers in pediatric oncology care.

Family history-taking practices and genetic confidence in primary and tertiary care providers for childhood cancer survivors. Pediatr Blood Cancer 2018; 65. [PMID: 29286558 DOI: 10.1002/pbc.26923] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2017] [Revised: 11/06/2017] [Accepted: 11/20/2017] [Indexed: 11/12/2022]
Abstract
BACKGROUND There is growing impetus for increased genetic screening in childhood cancer survivors. Family history-taking is a critical first step in determining survivors' suitability. However, the family history-taking practices of providers of pediatric oncology survivorship care and the confidence of these providers to discuss cancer risks to relatives are unknown. PROCEDURE Fifty-four providers completed semistructured interviews in total, which included eight tertiary providers representing nine hospitals across two countries (63% male, 63% oncologists, 37% nurses) and 46 primary care providers (PCPs) nominated by a survivor (59% male, 35% regional practice). We used content analysis and descriptive statistics/regression to analyze the data. RESULTS Few tertiary (38%) or primary (35%) providers regularly collected survivors' family histories, often relying on survivors/parents to initiate discussions. Providers mostly took two-generation pedigrees (63% tertiary and 81% primary). Primary providers focused on adult cancers. Lack of time, alternative priorities, and perceived lack of relevance were common barriers. Half of all tertiary providers felt moderately comfortable discussing genetic cancer risk to children of survivors (88% felt similarly discussing risks to other relatives). Most primary providers lacked confidence: 41% felt confident regarding risks to survivors' children and 48% regarding risks to other relatives. CONCLUSIONS While family history-taking will not identify all survivors suitable for genetics assessment, recommendations for regular history-taking are not being implemented in tertiary or primary care. Additional PCP-targeted genetic education is warranted given that they are well placed to review family histories of pediatric cancer survivors.

Abstract
Precision oncology applies genomic and other molecular analyses of tumor biopsies to improve the diagnosis and treatment of cancers. In addition to identifying therapeutic options, precision oncology tracks the response of a tumor to an intervention at the molecular level and detects drug resistance and the mechanisms by which it occurs. Integrative genomics can include sequencing specific panels of genes, exomes, or the entire triad of the patient's germline, tumor exome, and tumor transcriptome. Although the capabilities of sequencing technologies continue to improve, widespread adoption of genomics-driven precision oncology in the clinic has been held back by logistical, regulatory, financial, and ethical considerations. Nevertheless, integrative clinical sequencing programs applied at the point of care have the potential to improve the clinical management of cancer patients.

Abstract
The maturation of genomic technologies has enabled new discoveries in disease pathogenesis as well as new approaches to patient care. In pediatric oncology, patients may now receive individualized genomic analysis to identify molecular aberrations of relevance for diagnosis and/or treatment. In this context, several recent clinical studies have begun to explore the feasibility and utility of genomics-driven precision medicine. Here, we review the major developments in this field, discuss current limitations, and explore aspects of the clinical implementation of precision medicine, which lack consensus. Lastly, we discuss ongoing scientific efforts in this arena, which may yield future clinical applications.
