It involves a high risk of a variety of malignant tumors in childhood and adulthood, the main ones being premenopausal breast cancer, soft tissue sarcomas and osteosarcomas, central nervous system tumors, and adrenocortical carcinomas. The variability of the associated clinical manifestations, which do not always fit the classic criteria of Li-Fraumeni syndrome, has led the concept of SLF to extend to a more overarching cancer predisposition syndrome, termed hereditable TP53-related cancer syndrome (hTP53rc). However, prospective studies are needed to assess genotype–phenotype characteristics, as well as to evaluate and validate risk-adjusted recommendations. This guideline aims to establish the basis for interpreting pathogenic variants in the TP53 gene and provide recommendations for effective screening and prevention of associated cancers in carrier individuals.  \nKeywords Li-Fraumeni syndrome · TP53 · Cancer · Pathogenic variants  \n* Joan Brunet  \njbrunet@iconcologia.net  \nAna Beatriz Sánchez-Heras  \n[zrtbns@gmail.com](zrtbns@gmail.com)  \nTeresa Ramon y Cajal  \n[tramon@santpau.cat](tramon@santpau.cat)  \nMarta Pineda  \n[mpineda@iconcologia.net](mpineda@iconcologia.net)  \nElena Aguirre  \n[elenaaguirreortega@yahoo.es](elenaaguirreortega@yahoo.es)  \nBegoña Graña  \n[begona.grana.suarez@gmail.com](begona.grana.suarez@gmail.com)  \nIsabel Chirivella  \n[chirivella_isa@gva.es](chirivella_isa@gva.es)  \nJudit Balmaña  \n[jbalmana@vhio.net](jbalmana@vhio.net); [cnoguera@vhio.net](cnoguera@vhio.net)  \n1 Medical Oncology Department, Hospital General Universitario de Elche, Elche, Alicante, Spain  \n2 Medical Oncology Service, Hospital Sant Pau, Barcelona, Spain  \n3 Hereditary Cancer Program, Catalan Institute of Oncology, Institut d’Investigació Biomèdica de Bellvitge (IDIBELL), ONCOBELL Program, L’Hospitalet de Llobregat, Barcelona, Spain  \n4 Consortium for Biomedical Research in Cancer, CIBERONC, Carlos III Institute of Health, Madrid, Spain  \n5 Medical Oncology Department, Hospital Quironsalud, Zaragoza, Spain  \n6 Medical Oncology Department, University Hospital A Coruña, 15006 A Coruña, Spain  \n7 Medical Oncology Department, INCLIVA Biomedical Research Institute, University of Valencia, Valencia, Spain  \n8 Medical Oncology Department, Hospital Vall d’Hebron, and Hereditary Cancer Genetics Group, Vall d’Hebron Institute of Oncology, Barcelona, Spain  \n9 Medical Oncology Department, Catalan Institute of Oncology, University Hospital Josep Trueta, University of Girona, Girona, Spain  \n10 Hereditary Cancer Program, Catalan Institute of Oncology, Girona Biomedical Research Instiute (IDIBGI), Girona, Spain  \nIntroduction  \nLi-Fraumeni syndrome (LFS) is characterized by a high risk of developing a wide variety of malignant tumors in childhood and adulthood, caused by heterozygous germline pathogenic variants in the TP53 gene.
