Excerpt:
Analyses were done on basal (i.e.:before treatment) diagnostic or surgical sarcoma specimens obtained from patients treated with TR+OL and who did reach a 6-month progression-free survival (responder) or did not (non-responders)....the expression of CDKN2A, PI3KR1, SLFN11, ATM significantly higher in responders than in non-responder patients while APEX2, BLM, RAD54L, XRCC2, MAD2L2 was lower.
Secondary therapy:
trabectedin
