Metabolic active tumour volume quantified on [18F]FDG PET/CT further stratifies TNM stage IV non-small cell lung cancer patients

Purpose This study aimed to assess whether the whole body metabolic active tumour volume (MTV WB ), quantified on staging [ 18 F]FDG PET/CT, could further stratify stage IV non-small cell lung cancer (NSCLC) patients. Methods A group of 160 stage IV NSCLC patients, submitted to staging [ 18 F]FDG PE...

description Purpose This study aimed to assess whether the whole body metabolic active tumour volume (MTV WB ), quantified on staging [ 18 F]FDG PET/CT, could further stratify stage IV non-small cell lung cancer (NSCLC) patients. Methods A group of 160 stage IV NSCLC patients, submitted to staging [ 18 F]FDG PET/CT between July 2010 and May 2020, were retrospectively evaluated. MTV WB was quantified. Univariate and multivariate Cox regressions were carried out to assess correlation with overall survival (OS). C-statistic was used to test predictive power. Kaplan–Meier survival curves with Log-Rank tests were performed to compute statistical differences between strata from dichotomized variables and to calculate the estimated mean survival times (EMST). Survival rates at 1 and 5 years were calculated. Results MTV WB was a statistically significant predictor of OS on univariate ( p

Survival rates at 1 and 5 years were calculated. Results MTV WB was a statistically significant predictor of OS on univariate ( p  &lt; 0.0001) and multivariate analyses ( p  &lt; 0.0001). The multivariate model with MTV WB (Cindex ± SE = 0.657 ± 0.024) worked significantly better as an OS predictor than the cTNM model (Cindex ± SE = 0.544 ± 0.028) ( p  = 0.003). An EMST of 29.207 ± 3.627(95% CI 22.099–36.316) months and an EMST of 10.904 ± 1.171(95% CI 8.609–13.199) months (Log-Rank p  &lt; 0.0001) were determined for patients with MTV WB  &lt; 104.3 and MTV WB  ≥ 104.3, respectively. In subsamples of stage IVA (cut-off point = 114.5) and IVB patients (cut-off point = 191.1), statistically significant differences between EMST were also reported, with p-values of 0.0001 and 0.0002, respectively. In both substages and in the entire cohort, patients with MTV WB  ≥ cut-off points had lower EMST and survival rates. Conclusion Baseline MTV WB , measured on staging [ 18 F]FDG PET/CT, further stratifies stage IV NSCLC patients. This parameter is an independent predictor of OS and provides valuable prognostic information over the 8th edition of cTNM staging.</description><identifier>ISSN: 0171-5216</identifier><identifier>EISSN: 1432-1335</identifier><identifier>DOI: 10.1007/s00432-021-03799-w</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Cancer Research ; Hematology ; Internal Medicine ; Lung cancer ; Medicine ; Medicine &amp; Public Health ; Metabolism ; Non-small cell lung carcinoma ; Oncology ; Original Article – Cancer Research ; Small cell lung carcinoma ; Statistical analysis ; Tumors</subject><ispartof>Journal of cancer research and clinical oncology, 2021-12, Vol.147 (12), p.3601-3611</ispartof><rights>The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2021</rights><rights>The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2021.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c352t-50198556fbfd9c605fddf4e10677e798e85d8688a815eb90b33fc1b2003e69b63</citedby><cites>FETCH-LOGICAL-c352t-50198556fbfd9c605fddf4e10677e798e85d8688a815eb90b33fc1b2003e69b63</cites><orcidid>0000-0001-7836-8161 ; 0000-0002-2014-0399 ; 0000-0003-3051-4152 ; 0000-0002-4964-9746 ; 0000-0001-9855-0454 ; 0000-0003-3270-0119</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://link.springer.com/content/pdf/10.1007/s00432-021-03799-w$$EPDF$$P50$$Gspringer$$H</linktopdf><linktohtml>$$Uhttps://link.springer.com/10.1007/s00432-021-03799-w$$EHTML$$P50$$Gspringer$$H</linktohtml><link.rule.ids>314,780,784,27924,27925,41488,42557,51319</link.rule.ids></links><search><creatorcontrib>Rocha, Ana Luísa Gomes</creatorcontrib><creatorcontrib>da Conceição, Mauro Alessandro Monteiro</creatorcontrib><creatorcontrib>da Cunha Sequeira Mano, Francisco Xavier Proença</creatorcontrib><creatorcontrib>Martins, Helder Carvalho</creatorcontrib><creatorcontrib>Costa, Gracinda Maria Lopes Magalhães</creatorcontrib><creatorcontrib>Dos Santos Oliveiros Paiva, Bárbara Cecília Bessa</creatorcontrib><creatorcontrib>Lapa, Paula Alexandra Amado</creatorcontrib><title>Metabolic active tumour volume quantified on [18F]FDG PET/CT further stratifies TNM stage IV non-small cell lung cancer patients</title><title>Journal of cancer research and clinical oncology</title><addtitle>J Cancer Res Clin Oncol</addtitle><description>Purpose This study aimed to assess whether the whole body metabolic active tumour volume (MTV WB ), quantified on staging [ 18 F]FDG PET/CT, could further stratify stage IV non-small cell lung cancer (NSCLC) patients.
