&lt;i&gt;Objectives:&lt;/i&gt; We evaluated prognostic factors affecting relapse-free survival (RFS) and overall survival (OS), and investigated the role of adjuvant chemotherapy in patients with small bowel adenocarcinoma (SBA). &lt;i&gt;Methods:&lt;/i&gt; Data from 52 patients with SBA who underwent curative surgery at the Asan Medical Center between January 1989 and December 2009 were retrospectively analyzed. Patients were divided into two groups: those who did (n = 23) and did not (n = 29) receive adjuvant chemotherapy. &lt;i&gt;Results:&lt;/i&gt; At a median follow-up of 32.2 months (range, 5.5–212.2 months), relapses had occurred in 17 patients (32.7%), with a 5-year RFS rate of 52.9% (95% CI, 39.3–66.5%), and 19 patients (36.5%) had died, with a 5-year OS rate of 59.0% (95% CI, 45.6–72.4%). The most frequent sites of relapse were the peritoneum and liver. Multivariate analysis showed that lymph node involvement was the only factor independently associated with poor RFS and OS. After inverse probability of treatment weighting adjustment, adjuvant chemotherapy did not enhance RFS [hazard ratio (HR), 1.399; 95% CI, 0.498–3.933] or OS (HR 0.797; 95% CI, 0.307–2.068). &lt;i&gt;Conclusions:&lt;/i&gt; Lymph node involvement is a predictor of poor prognosis in patients with SBA who undergo curative surgery.</jats:p
