ABSTRACT<br />

Data from two populations of patients receiving stem cell <strong>transplantation</strong> (SCT)<br />

for non-Hodgkin's lymphoma (NHL) were analyzed for patterns of relapse after<br />

<strong>transplantation</strong>, including time to relapse, the frequency of local vs. distant relapse,<br />

<strong>and</strong> survival after relapse. Group A comprised 106 patients receiving high-dose<br />

therapy <strong>and</strong> <strong>autologous</strong> SCT at the University of Southampton, U.K. Group B<br />

comprised 1339 patients with NHL relapsing after SCT <strong>and</strong> with documented sites<br />

of relapse recorded on the lymphoma registry of the European Group for Blood <strong>and</strong><br />

Marrow Transplantation (EBMT). In group A, of the 106 patients undergoing<br />

autoSCT, 91 had diffuse large B cell NHL (including 13 with transformed<br />

follicular lymphoma); 57 (54%) relapsed at a median of 9 months following SCT;<br />

36 (63%) of these relapsed in local/locoregional sites, 15 (27%) in distant sites, <strong>and</strong><br />

six (10%) at both local <strong>and</strong> distant sites. The median overall survival (OS) from<br />

the date of relapse was 3 months. No difference in OS was seen according to the<br />

site of relapse. In group B, of the 1339 patients, 187 had low-grade NHL, 393<br />

intermediate grade, 245 lymphoblastic lymphoma (LBL), 75 Burkitt's or Burkittlike<br />

(BL), <strong>and</strong> 439 other high-grade subtypes. Two hundred fifty-nine (19%) of<br />

patients relapsed at local/locoregional sites, <strong>and</strong> 1080 at distant sites ± sites of<br />

previous involvement. Local relapse was more frequent in patients with low-,<br />

intermediate-, or other high-grade disease, compared with LBL or BL histology (21<br />

vs. 22 vs. 20 vs. 12 vs. 15%, respectively, P=0.016), in patients with single-site<br />

disease before SCT compared with those with multiple sites (P<br />
