A geriatric evaluation should at a minimum include the use of a brief geriatric screening tool. Tools in the Practical Geriatric Assessment (PGA) are validated in multiple languages, but users may use more appropriate tools in some settings and languages, if they include the relevant guideline-specified domains. Maximal-resource settings of high-income countries have traditionally developed cutoffs for GA-identified deficits, but locally validated research and practice may inform differing cutoffs. If validated all-cause mortality prognosis tools do not adequately represent the setting, clinicians may use actuarial life-expectancy tables with quartiles of overall health status.<\/jats:p>\n \n Additional information can be found at<\/jats:italic>\n www.asco.org\/global-guidelines<\/jats:ext-link>\n . It is the view of ASCO that health care clinicians and health care system decision makers should be guided by the recommendations for the highest stratum of resources available. The guideline is intended to complement but not replace local guidelines.<\/jats:italic>\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1200\/go-25-00276","type":"journal-article","created":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T19:59:13Z","timestamp":1756324753000},"update-policy":"https:\/\/doi.org\/10.1200\/crossmark","source":"Crossref","is-referenced-by-count":27,"title":["Geriatric Assessment: ASCO Global Guideline"],"prefix":"10.1200","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0037-0303","authenticated-orcid":true,"given":"Cristiane Decat","family":"Bergerot","sequence":"first","affiliation":[{"name":"Oncoclinicas&Co - Medica Scientia Innovation Research (MEDSIR), Brasilia, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1834-0551","authenticated-orcid":true,"given":"Sarah","family":"Temin","sequence":"additional","affiliation":[{"name":"American Society of Clinical Oncology (ASCO), Alexandria, VA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2300-7075","authenticated-orcid":true,"given":"Haydee C.","family":"Verduzco-Aguirre","sequence":"additional","affiliation":[{"name":"Instituto Nacional de Ciencias M\u00e9dicas y Nutrici\u00f3n, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matti S.","family":"Aapro","sequence":"additional","affiliation":[{"name":"Genolier Cancer Center, Genolier, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7815-6046","authenticated-orcid":true,"given":"Shabbir M.H.","family":"Alibhai","sequence":"additional","affiliation":[{"name":"Princess Margaret Cancer Centre, Toronto, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5032-4503","authenticated-orcid":true,"given":"Zeba","family":"Aziz","sequence":"additional","affiliation":[{"name":"Hameed Latif Hospital, Lahore, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2302-2774","authenticated-orcid":true,"given":"Mar\u00eda de la Concepci\u00f3n P\u00e9rez","family":"de Celis Herrero","sequence":"additional","affiliation":[{"name":"Benem\u00e9rita Universidad Aut\u00f3noma de Puebla, Puebla, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5412-6918","authenticated-orcid":true,"given":"Trinanjan","family":"Basu","sequence":"additional","affiliation":[{"name":"HCG Cancer Centre, Mumbai, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4381-1199","authenticated-orcid":true,"given":"Martine","family":"Extermann","sequence":"additional","affiliation":[{"name":"H.
