Clinicopathologic features and prognosis of gastric cancer in young patients / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinicopathologic features and prognosis of gastric cancer in young patients (YGC) in order to improve the treatment outcome of YGC.</p><p><b>METHODS</b>Clinical data of 63 YGC patients (40 years of age and less) who underwent surgery from January 2004 to December 2006 were analyzed retrospectively. A total of 654 older gastric cancer patients (OGC, above 40 years) during the same period patients were selected and compared to the YGC patients.</p><p><b>RESULTS</b>The proportions of female patients, patients with a family history or with undifferentiated tumor in YGC were significantly higher than OGC (all P<0.05). The curative resection rate of YGC patients was 61.9% (39/63), significantly lower than that of OGC (93.1%, 595/654, P<0.01). A total of 653 (91.1%) patients were followed up, with a period of time of 1 to 84 months. The 5-year survival rates for YGC and OGC patients were 40.5% and 55.6% respectively, and the difference was statistically significant (P<0.05). Cox proportional hazards model showed that the depth of invasion, lymph node metastasis, and radical surgery were the independent factors associated with the prognosis of YGC (all P<0.05). The stratified analysis showed that the 5-year survival rates for YGC and OGC patients undergoing radical surgery were 63.2% and 56.7% respectively and the difference was not statistically significant (P>0.05). The 5-year survival rates for YGC and OGC patients undergoing palliative surgery were 4.2% and 22.2% respectively and the difference was statistically significan t(P<0.05).</p><p><b>CONCLUSION</b>Gastric cancer in young patients is highly malignant, with lower rate of curative resection and poorer prognosis. The long-term outcome of YGC is similar to that of OGC if radical resection is possible.</p>
