We recruited 53 patients, who underwent pre-treatment 2-[18F]-FDG PET\/CT and end-of-treatment PET\/CT, and the main semiquantitative parameters were calculated. Sarcopenia was measured as skeletal muscle index (SMI, cm2\/m2) and derived by low-dose PET\/CT images at the L3 level. Specific cut-offs for SMI were calculated by receiver operator curve and divided by gender. Metabolic response was evaluated at end-of-treatment PET\/CT, applying the Deauville score. Progression Free Survival (PFS) and Overall Survival (OS) were calculated for the whole population and for different subgroups, defined as per different sarcopenia cut-off levels. The specific cut-offs to define sarcopenia were 53 cm2\/m2 for male and 45.6 cm2\/m2 for female. Thirty-two (60%) patients were defined as sarcopenic. The 3-year and 5-year PFS rates were 29% and 23%, while the 3-year and 5-year OS rates were 43% and 33%. Metabolic response, total metabolic tumor volume (tMTV), total lesion glycolysis (tTLG) and sarcopenia were independent prognostic factors for PFS. Considering OS, no variable was significantly associated. Combination between PET features and sarcopenia may help to predict PFS.<\/jats:p>","DOI":"10.3390\/jcm11051210","type":"journal-article","created":{"date-parts":[[2022,2,23]],"date-time":"2022-02-23T22:54:02Z","timestamp":1645656842000},"page":"1210","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Prognostic Role of Pre-Treatment Metabolic Parameters and Sarcopenia Derived by 2-[18F]-FDG PET\/CT in Elderly Mantle Cell Lymphoma"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0810-6494","authenticated-orcid":false,"given":"Domenico","family":"Albano","sequence":"first","affiliation":[{"name":"Nuclear Medicine, ASST Spedali Civili Brescia, 25128 Brescia, Italy"},{"name":"Nuclear Medicine Department, University of Brescia, 25121 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nadia","family":"Pasinetti","sequence":"additional","affiliation":[{"name":"Radiation Oncology Department, ASST Valcamonica Esine and University of Brescia, 25128 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4839-9033","authenticated-orcid":false,"given":"Francesco","family":"Dondi","sequence":"additional","affiliation":[{"name":"Nuclear Medicine, ASST Spedali Civili Brescia, 25128 Brescia, Italy"},{"name":"Nuclear Medicine Department, University of Brescia, 25121 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raffaele","family":"Giubbini","sequence":"additional","affiliation":[{"name":"Nuclear Medicine Department, University of Brescia, 25121 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandra","family":"Tucci","sequence":"additional","affiliation":[{"name":"Hematology, ASST Spedali Civili of Brescia, 25128 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Bertagna","sequence":"additional","affiliation":[{"name":"Nuclear Medicine, ASST Spedali Civili Brescia, 25128 Brescia, Italy"},{"name":"Nuclear Medicine Department, University of Brescia, 25121 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,23]]},"reference":[{"key":"ref_1","unstructured":"Swerdlow, S.H., Campo, E., Harris, N.L., Jaffe, E.S., Pileri, S.A., Stein, H., and Thiele, J.
