JCO 1996 92:405-10) • Grade IV anemia and thrombocytopenia (Ray-Coquard I. et al. JCO 1999 17:2840-6) • Increased risk of Early Death (48%) (Ray-Coquard I. et al. Br J Cancer 2001 85:816-22) • Lymphopenia detected before chemotherapy is an independent pronostic factor for overall survival in metastatic solid tumors (Borg C et al. Cancer 2004 101:2675-80; Ray-Coquard I. et al Cancer Res 2009 69:5383-91) Metastatic Breast Carcinoma (n= 290) Overall survival (%) Overall survival (%) Log Rank test =21.5, p<0.01 100 80 lymphocytes (/µL) >1000/µL <1000/µL 60 40 20 0 Soft tissue Sarcoma (n=193) 0 20 40 60 Months DATE 80 100 100 90 80 70 60 50 40 30 20 10 0 Log Rank test: p=0.0057 lymphocytes (/µL) >1000/µL <1000/µL 0 1 2 3 NOM DE LA PRÉSENTATION (INSERTION - EN-TÊTE ET PIED DE PAGE) 7 4 5 6 8 Years SOUS L'ÉGIDE DE LA FONDATION BULLUKIAN 3 ImmunID Technology to assess TCR diversity Identification of V-J rearrangements at the genomic level Stability of samples Avoid bias due to transcriptional regulation (1 cell = 1 rearrangement) PCR multi-N-plex (V-J) Example : TRAD Locus Flow Cytometry (V) Spectratyping & Sequencing (CDR3) V genes J genes AC gDNA A C Vn Ji V-Ja Env. 10Kb Rearrangement Splicing Vn - Ji A C Hz Combinatorial diversity : V x (D) x J Jonction diversity: CDR3 V Matching diversity : TCRa x TCRb Somatic hypermutations SOUS L'ÉGIDE DE LA FONDATION BULLUKIAN J TCR repertoire diversity is altered in metastatic breast cancer patients and has an added value to lymphopenia status Divpenia<1st tertile Lymphopenic Patients Non Lymphopenic Patients SOUS L'ÉGIDE DE LA FONDATION BULLUKIAN Comparaison of the distribution of patients according to the NDL score Metastatic Breast Cancer Patients Healthy donors NDL4 NDL3 NDL4 NDL1 NDL2 NDL1 NDL2 Lymphocyte absolute Numbe (Giga/L) NDL3 combinatorial diversity hTRB VJ (%) Does NDL classification help to discriminate patients prognosis ?
