Study design <strong>and</strong> data management of this prospective r<strong>and</strong>omized study were<br />

detailed previously. 14<br />

Analysis was based on status of disease on 1 December 1997.<br />

Actuarial curves were estimated according to the Kaplan <strong>and</strong> Meier 17<br />

method <strong>and</strong><br />

compared by the log-rank test. The relationship between parameters <strong>and</strong> outcome<br />

was examined by univariate <strong>and</strong> multivariate analysis according to Cox's hazard<br />

regression model. 18<br />

Test statistics for comparison of main objectives were regarded<br />

as significant if the two-sided P value was less than 0.05.<br />

Survival analysis according to a number of prognostic factors was performed.<br />

Prognostic factors taken into account in the stepwise Cox analysis were as follows:<br />

sex, performance status (0-1 vs. >1), histology (F vs. G vs. H + K), symptoms (A<br />

vs. B), bulky disease (>10 cm vs. others), number of extranodal sites (0 vs. 1 vs. >1),<br />

<strong>and</strong> lactate dehydrogenase (LDH) level (1X normal value). Survival,<br />

DFS, <strong>and</strong> PFS were also retrospectively analyzed according to the International<br />

Non-Hodgkin's Lymphoma Prognostic Factors Project (International Index). The<br />

results were adjusted for age 1, LDH level<br />

>1X normal value, <strong>and</strong> stage >II. Patients in the two arms also appeared to be<br />

balanced if categorized according to the International Index (Table 1).<br />

RESULTS<br />

Response to treatment <strong>and</strong> toxicity<br />

Arm A: after VACOP-B therapy, 34 (56%) <strong>and</strong> 19 (31%) patients achieved CR<br />

<strong>and</strong> PR, respectively. Six patients progressed, <strong>and</strong> two died of toxicity. Twelve<br />

(19%) additional PR patients obtained CR. Three patients achieved CR after<br />

radiotherapy alone, six after DHAP regimen, <strong>and</strong> three after autoBMT while in<br />

persistent PR following DHAP therapy (one of them relapsed). Another three<br />

patients received autoBMT while resistant to DHAP regimen but did not respond<br />

to the procedure. In conclusion, 46 (75%) of 61 patients achieved CR. Grade 3 <strong>and</strong><br />

4 WHO hematological toxicity was observed in
