Neutrophils in Bone Sarcomas (TANOs)
Hypothesis: Tumor infiltrating neutrophils are present in osteosarcomas and chondrosarcomas and Experimental design: Exploratory observational research Population: Adult patients with osteosarcoma or chondrosarcoma Assessment criteria: Determination of the presence of TANs within tumors and their N1 or N2 profile, the presence of other immune cells, and the PDL-1 status of the tumor. Investigation plan: Proposal to participate at all eligible patient during the preoperative consultation. If the patient agrees to participate in the study he/she will be included. Participation in the study will not affect its coverage. Patient participation will lead to: * Taking samples from an operative part, * The collection of demographic data (age, sex, height, weight, body mass index), family history of cancer, history of bone trauma, sports practice, clinical and anatomopathology reports and data, medical history (Diabetes, Cardiovascular Diseases, Infectious Diseases, Autoimmune Diseases, Bone Metabolism Disorders, Allergies, Menopause, Drug treatments followed, Psychiatric disorders). Statistical analysis plan: Description in frequency of the presence of TANs, of N1 and N2 profiles, of the presence of other immune cells both qualitatively and quantitatively. Analysis in subgroups on relevant criteria (age, sex, location, type of tumor).
