    Abstract:
    Fifty-seven patients treated by radical gastric resections were retrospectively studied to understand the clinicopathologic characteristics of advanced gastric cancer without serosal invasion (the depth of tumor invasion limited to the muscularis propria or subserosal layer) in young and old age persons. There were 36 patients in the old age group (age > 60 years) and 21 in the young age group (age < or = 40 years). The clinical and pathologic parameters for this study included sex, gross type, location, maximum tumor size, depth of invasion, lymph node metastasis, tumor stage, histologic type, and rate of curative resection. The old patients had a higher percentage of small tumors, subserosal invasion and lymph node metastasis, but these parameters were not significantly different from those of the young patients, nor did the sex ratio, gross type, location, and rate of curative resection show significant differences. The histologic feature was the only statistically significant parameter, determined by univariate and multivariate analyses. Poorly differentiated adenocarcinoma and signet ring cell carcinoma were detected in 10 (47.6%) and 4 (19.0%) of the 21 younger patients, respectively, while there were 4 (11.1%) and 2 (5.6%) in the old age group. Although the gastric cancer in young patients had more aggressive histologic characteristics than it did in elderly patients, survival rates between the two groups did not differ to any great degree. Our findings indicate that the prognosis for younger patients with advanced gastric cancer without serosal invasion was favorable when curative resection was performed.
