The availability of multiomics data catalogs for large cohorts of cancer patients provides multiple views into the molecular biology of the tumors with unprecedented resolution.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We develop Pathway-based MultiOmic Graph Kernel clustering (PAMOGK) that integrates multiomics patient data with existing biological knowledge on pathways. We develop a novel graph kernel that evaluates patient similarities based on a single molecular alteration type in the context of a pathway. To corroborate multiple views of patients evaluated by hundreds of pathways and molecular alteration combinations, we use multiview kernel clustering. Applying PAMOGK to kidney renal clear cell carcinoma (KIRC) patients results in four clusters with significantly different survival times (P-value =1.24e\u221211). When we compare PAMOGK to eight other state-of-the-art multiomics clustering methods, PAMOGK consistently outperforms these in terms of its ability to partition KIRC patients into groups with different survival distributions. The discovered patient subgroups also differ with respect to other clinical parameters such as tumor stage and grade, and primary tumor and metastasis tumor spreads. The pathways identified as important are highly relevant to KIRC.<\/jats:p><\/jats:sec><jats:sec><jats:title>Availability and implementation<\/jats:title><jats:p>github.com\/tastanlab\/pamogk.<\/jats:p><\/jats:sec><jats:sec><jats:title>Supplementary information<\/jats:title><jats:p>Supplementary data are available at Bioinformatics online.<\/jats:p><\/jats:sec>","DOI":"10.1093\/bioinformatics\/btaa655","type":"journal-article","created":{"date-parts":[[2020,7,22]],"date-time":"2020-07-22T19:24:53Z","timestamp":1595445893000},"page":"5237-5246","source":"Crossref","is-referenced-by-count":26,"title":["PAMOGK: a pathway graph kernel-based multiomics approach for patient clustering"],"prefix":"10.1093","volume":"36","author":[{"given":"Yasin Ilkagan","family":"Tepeli","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, Faculty of Engineering and Natural Sciences, Sabanci University , Istanbul 34956, Turkey"}]},{"given":"Ali Burak","family":"\u00dcnal","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Faculty of Engineering and Natural Sciences, Sabanci University , Istanbul 34956, Turkey"},{"name":"Department of Computer Engineering, Bilkent University , Ankara 06800, Turkey"}]},{"given":"Furkan Mustafa","family":"Akdemir","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, Bilkent University , Ankara 06800, Turkey"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7058-5372","authenticated-orcid":false,"given":"Oznur","family":"Tastan","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Faculty of Engineering and Natural Sciences, Sabanci University , Istanbul 34956, Turkey"}]}],"member":"286","published-online":{"date-parts":[[2020,7,30]]},"reference":[{"key":"2023062408071793300_btaa655-B1","doi-asserted-by":"crossref","first-page":"658","DOI":"10.4161\/cbt.10.7.13247","article-title":"Signaling pathways in renal cell carcinoma","volume":"10","author":"Banumathy","year":"2010","journal-title":"Cancer Biol.
