Over 10 years to 2016, 12906 diagnoses were registered (ICD10: C00-C80), with 18.84% of cases, and 63.9% of data points complete. Two sites were quality assured with high completion rates (H&amp;amp;N &amp;ndash; 97.4% [4.26% of total cases], RECTUM &amp;ndash; 88.74% [4.06%]). Sites lacking clinician attention varied from poor (eg, LUNG &amp;ndash; 23.23% [13.24%]) to largely incomplete (eg, BRAIN &amp;ndash; 2.01% [0.38%]).This disappointing medical data completion rate makes its use in a &amp;lsquo;Big Data&amp;rsquo; effort suspect. Data extrapolation is compromised by variable natural history. Extrapolation techniques are unlikely to cope with only 18.84% complete data. Data mining requires input from domain experts. The 4 requirements of Big Data are not evident in oncological data.<\/jats:p>","DOI":"10.3233\/978-1-61499-880-8-149","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T15:10:01Z","timestamp":1740150601000},"source":"Crossref","is-referenced-by-count":0,"title":["Oncology Information System Data &amp;ndash; Implications for &amp;lsquo;Big Data&amp;rsquo;"],"prefix":"10.3233","author":[{"family":"Miller Alexis Andrew","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Data, Informatics and Technology: An Inspiration for Improved Healthcare"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T15:50:40Z","timestamp":1740153040000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISBN&isbn=978-1-61499-879-2&spage=149&doi=10.3233\/978-1-61499-880-8-149"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-880-8-149","relation":{},"ISSN":["0926-9630"],"issn-type":[{"value":"0926-9630","type":"print"}],"subject":[],"published":{"date-parts":[[2018]]}}}
