News Finding: The median disease-free survival was 13.4 months in the treatment group compared with 6.7 months in the observation group.
Paper Finding: The median disease-free survival was 13.4 (95% CI, 11.6-15.3) months in the treatment group compared with 6.7 (95% CI, 6.0-7.5) months in the observation group (hazard ratio, 0.55 [95% CI, 0.44-0.69]; P < .001).
News Context: The median (midpoint) follow-up time was 136 months (11.3 years). The median disease-free survival was 13.4 months in the treatment group compared with 6.7 months in the observation group. By the end of the follow-up period, 316 patients (89.3 percent) had died and 38 patients were still alive, 23 in the treatment group and 15 in the observation group.

The median disease-free survival was 13.4 (95% CI, 11.6-15.3) months in the treatment group compared with 6.7 (95% CI, 6.0-7.5) months in the observation group (hazard ratio, 0.55 [95% CI, 0.44-0.69]; P < .001). Patients randomized to adjuvant gemcitabine treatment had prolonged overall survival compared with those randomized to observation alone (hazard ratio, 0.76 [95% CI, 0.61-0.95]; P = .01), with 5-year overall survival of 20.7% (95% CI, 14.7%-26.6%) vs 10.4% (95% CI, 5.9%-15.0%), respectively, and 10-year overall survival of 12.2% (95% CI, 7.3%-17.2%) vs 7.7% (95% CI, 3.6%-11.8%).
