Value of Biopsy Data in HL
The diagnostic and relapse biopsies, as well as clinical outcome data were compared in this study to determine the biology associated with resistance to first-line therapy in Hodgkin lymphoma (HL), as well as identify prognostic markers. Findings were presented at the 2014 American Society of Hematology annual meeting. Biopsies (n = 245) were sampled from 174 patients with classical HL.
Inferior post-high-dose chemotherapy and autologous stem cell transplantation failure-free survival were seen in patients with poorly correlated biopsy pairs (five-year failure-free survival: poorly correlated 39% versus well correlated 68%; log-rank p = 0.005).
