The Landscape of US and Global Rare Tumor Research Programs: A Systematic Review.

Rare cancers and other rare nonmalignant tumors comprise 25% of all cancer diagnoses and account for 25% of all cancer deaths. They are difficult to study due to many factors, including infrequent occurrence, lack of a universal infrastructure for data and/or tissue collection, and a paucity of disease models to test potential treatments. For each individual rare cancer, the limited number of diagnosed cases makes it difficult to recruit sufficient patients for clinical studies, and rare cancer research studies are often siloed. As a result, progress has been slow for many of these cancers. While rare cancer research efforts have increased over time, the breadth of the research landscape is not known. A recent literature search revealed a sharp increase in rare tumor, and rare cancer publications began in the early 2000s. To identify rare cancer research efforts being conducted in the US and globally, we conducted an online search of rare tumor/rare cancer research programs and identified 76 programs. To gain a deeper understanding of these programs, we composed and conducted a survey to ask programs for details about their research efforts. Of the 42 programs contacted to complete the survey, 23 programs responded. Survey results show most programs are collecting clinical data, molecular data, and biospecimens, and many are conducting molecular analyses. This landscape analysis demonstrates that multiple rare cancer research efforts are ongoing, and the rare cancer community may benefit from collaboration among stakeholders to accelerate research and improve patient outcomes.

Longitudinal Natural History Study of Children and Adults with Rare Solid Tumors: Initial Results for First 200 Participants.

Understanding of tumor biology and identification of effective therapies is lacking for many rare tumors. My Pediatric and Adult Rare Tumor (MyPART) network was established to engage patients, advocates, and researchers and conduct a comprehensive longitudinal Natural History Study of Rare Solid Tumors. Through remote or in-person enrollment at the NIH Clinical Center, participants with rare solid tumors ≥4 weeks old complete standardized medical and family history forms, patient reported outcomes, and provide tumor, blood and/or saliva samples. Medical records are extracted for clinical status and treatment history, and tumors undergo genomic analysis. A total of 200 participants (65% female, 35% male, median age at diagnosis 43 years, range = 2-77) enrolled from 46 U.S. states and nine other countries (46% remote, 55% in-person). Frequent diagnoses were neuroendocrine neoplasms (NEN), adrenocortical carcinomas (ACC), medullary thyroid carcinomas (MTC), succinate dehydrogenase (SDH)-deficient gastrointestinal stromal tumors (sdGIST), and chordomas. At enrollment, median years since diagnosis was 3.5 (range = 0-36.6), 63% participants had metastatic disease and 20% had no evidence of disease. Pathogenic germline and tumor mutations included SDHA/B/C (sdGIST), RET (MTC), TP53 and CTNNB1 (ACC), MEN1 (NEN), and SMARCB1 (poorly-differentiated chordoma). Clinically significant anxiety was observed in 20%-35% of adults. Enrollment of participants and comprehensive data collection were feasible. Remote enrollment was critical during the COVID-19 pandemic. Over 30 patients were enrolled with ACC, NEN, and sdGIST, allowing for clinical/genomic analyses across tumors. Longitudinal follow-up and expansion of cohorts are ongoing to advance understanding of disease course and establish external controls for interventional trials. SIGNIFICANCE: This study demonstrates that comprehensive, tumor-agnostic data and biospecimen collection is feasible to characterize different rare tumors, and speed progress in research. The findings will be foundational to developing external controls groups for single-arm interventional trials, where randomized control trials cannot be conducted because of small patient populations.

NCI intramural program approach to rare tumors: Natural history study of rare solid tumors in children and adults: A longitudinal, comprehensive data and biospecimen collection protocol.

Rare tumors across the world are lacking adequate knowledge, resources, and community. Through partnership with patients, advocacy organizations, researchers, and clinicians, we have developed a comprehensive, longitudinal, prospective, and retrospective natural history protocol to collect, analyze, and share data on patients with rare tumors. A strong collaborative effort is vital to ensure success of enrollment, patient engagement, data collection, and analysis to ultimately develop clinical trials to improve outcomes for patients with rare cancers.

The US President's Cancer Panel: A Model For Gathering Country-Level Input to Inform Cancer Control Policy and Program Initiatives.

PURPOSE: The President's Cancer Panel (Panel) is a federal advisory committee charged with monitoring the US National Cancer Program and reporting directly to the US President. Since its creation a half century ago, the Panel has gathered input from individuals and organizations across the US cancer community and beyond and recommended actions to accelerate progress against cancer. The Panel is unique in its structure and function, and merits examination for its potential applicability in other settings worldwide. METHODS: We present an overview of the general President's Cancer Panel model and describe the noteworthy and unique characteristics of the Panel that help achieve its charge. We also detail the specific processes, outputs, and achievements of the Panel appointed by President Barack Obama, which served between 2012 and 2018. RESULTS: From 2012 to 2018, the Panel focused on three topics that addressed timely issues in cancer prevention and control: (1) HPV vaccination for cancer prevention, (2) connected health and cancer, and (3) value and affordability of cancer drug treatment. The Panel held 11 meetings with 165 participants who provided diverse perspectives on these issues. Four reports were delivered to the president, which were cited about 270 times in the literature. Over 20 collaborator activities, including commitments of funding, can be linked to the recommendations published in these reports. CONCLUSION: The US President's Cancer Panel highlights the importance of independent advisory bodies within a national cancer control program and of national leadership support for the cancer community. The structure and function of the Panel could be applicable in other settings worldwide.
