Cancer-associated weight loss can occur years before the malignancy is diagnosed. This might have led to underestimation of the BMI-PC association. However, it is unknown if and to what extent this issue has been considered in previous epidemiological studies. We searched two databases through February 19, 2024 for systematic reviews, meta-analyses, and pooled analyses examining the BMI-PC association. We extracted information on study design with a special focus on the article's examination of prediagnostic weight loss as a potential source of bias, as well as how included cohort studies addressed this concern. Thirteen review articles, meta-analyses, and pooled analyses were identified. Only five (four pooled analyses, one systematic review) considered prediagnostic weight loss in their analyses. Twenty-four of 32 identified cohort studies reported having excluded initial years of follow-up. However, only 13 studies reported results after such exclusions, and effect estimates generally increased with longer periods of exclusion. We conclude that the association of overweight and obesity with PC risk is likely larger than suggested by published epidemiological evidence. Future studies should pay careful attention to avoid or minimize potential bias resulting from prediagnostic weight loss. 000291928 536__ $$0G:(DE-HGF)POF4-313$$a313 - Krebsrisikofaktoren und Prävention (POF4-313)$$cPOF4-313$$fPOF IV$$x0 000291928 588__ $$aDataset connected to CrossRef, PubMed, , Journals: inrepo02.dkfz.de 000291928 650_7 $$2Other$$aobesity 000291928 650_7 $$2Other$$aoverweight 000291928 650_7 $$2Other$$apancreatic cancer 000291928 650_7 $$2Other$$aweight loss 000291928 7001_ $$0P:(DE-He78)3772dc9cbbc020fbc52b5f63f1dc1e96$$aPulte, Dianne$$b1$$udkfz 000291928 7001_ $$0P:(DE-He78)a15e13b5e2dfc276ddddbf7505023951$$aSafizadeh, Fatemeh$$b2$$udkfz 000291928 7001_ $$0P:(DE-He78)20dc4ad11ff465acf5b99f1e679e10b7$$aNiedermaier, Tobias$$b3$$udkfz 000291928 7001_ $$0P:(DE-He78)6c5d058b7552d071a7fa4c5e943fff0f$$aHoffmeister, Michael$$b4$$udkfz 000291928 7001_ $$0P:(DE-He78)90d5535ff896e70eed81f4a4f6f22ae2$$aBrenner, Hermann$$b5$$eLast author$$udkfz 000291928 773__ $$0PERI:(DE-600)2020497-8$$a10.1111/obr.13799$$gp. e13799$$n10$$pe13799$$tObesity reviews$$v25$$x1467-7881$$y2024 000291928 8564_ $$uhttps://inrepo02.dkfz.de/record/291928/files/Obesity%20Reviews%20-%202024%20-%20Mandic%20-%20Overcoming%20underestimation%20of%20the%20association%20of%20excess%20weight%20with%20pancreatic%20cancer%20due.pdf 000291928 8564_ $$uhttps://inrepo02.dkfz.de/record/291928/files/Obesity%20Reviews%20-%202024%20-%20Mandic%20-%20Overcoming%20underestimation%20of%20the%20association%20of%20excess%20weight%20with%20pancreatic%20cancer%20due.pdf?subformat=pdfa$$xpdfa 000291928 909CO $$ooai:inrepo02.dkfz.de:291928$$pVDB 000291928 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)6c325c717056d7ccd38066629f7dff6b$$aDeutsches Krebsforschungszentrum$$b0$$kDKFZ 000291928 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)3772dc9cbbc020fbc52b5f63f1dc1e96$$aDeutsches Krebsforschungszentrum$$b1$$kDKFZ 000291928 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)a15e13b5e2dfc276ddddbf7505023951$$aDeutsches Krebsforschungszentrum$$b2$$kDKFZ 000291928 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)20dc4ad11ff465acf5b99f1e679e10b7$$aDeutsches Krebsforschungszentrum$$b3$$kDKFZ 000291928 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)6c5d058b7552d071a7fa4c5e943fff0f$$aDeutsches Krebsforschungszentrum$$b4$$kDKFZ 000291928 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)90d5535ff896e70eed81f4a4f6f22ae2$$aDeutsches Krebsforschungszentrum$$b5$$kDKFZ 000291928 9131_ $$0G:(DE-HGF)POF4-313$$1G:(DE-HGF)POF4-310$$2G:(DE-HGF)POF4-300$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vKrebsrisikofaktoren und Prävention$$x0 000291928 9141_ $$y2024 000291928 915__ $$0StatID:(DE-HGF)3001$$2StatID$$aDEAL Wiley$$d2023-08-24$$wger 000291928 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bOBES REV : 2022$$d2023-08-24 000291928 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2023-08-24 000291928 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2023-08-24 000291928 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2023-08-24 000291928 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2023-08-24 000291928 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2023-08-24 000291928 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2023-08-24 000291928 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2023-08-24 000291928 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2023-08-24 000291928 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents - Clinical Medicine$$d2023-08-24 000291928 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bOBES REV : 2022$$d2023-08-24 000291928 9202_ $$0I:(DE-He78)C070-20160331$$kC070$$lC070 Klinische Epidemiologie und Alternf.$$x0 000291928 9202_ $$0I:(DE-He78)C120-20160331$$kC120$$lPräventive Onkologie$$x1 000291928 9201_ $$0I:(DE-He78)C070-20160331$$kC070$$lC070 Klinische Epidemiologie und Alternf.$$x0 000291928 9201_ $$0I:(DE-He78)C120-20160331$$kC120$$lPräventive Onkologie$$x1 000291928 9201_ $$0I:(DE-He78)HD01-20160331$$kHD01$$lDKTK HD zentral$$x2 000291928 9200_ $$0I:(DE-He78)C070-20160331$$kC070$$lC070 Klinische Epidemiologie und Alternf.$$x0 000291928 980__ $$ajournal 000291928 980__ $$aVDB 000291928 980__ $$aI:(DE-He78)C070-20160331 000291928 980__ $$aI:(DE-He78)C120-20160331 000291928 980__ $$aI:(DE-He78)HD01-20160331 000291928 980__ $$aUNRESTRICTED
