“…Survival rates for the gastric cancer patients treated with noncurative resection, of positive lymph node metastasis, or treated with lymph node dissection of RO and R1 were lower than those treated with curative resection, of negative lymph node metastasis, or treated with lymph node dissection of R2 and R3, respectively DISCUSSION Gastric cancer that invades the subserosa may advance to the serosa and to other sites; therefore, growth pattern is an important biological characteristic which influences the survival of patients with ss gastric cancers [I]. The prognostic difference between the ss infiltrative type and noninfiltrative type of invasion of ss cancers has been discussed by other investigators [2,6]. As the survival time of patients with ss infiltrative gastric cancer was similar to that of patients with gastric cancer invading the serosa (se), ssy gastric cancer was included in the ps( +) group in the General Rules for the Gastric Cancer Study in Surgery and Pathology in Japan [ 11.…”

Gastric cancer invading the subserosa with infiltrative growth was classified as part of the serosal invasion group and named prognostic serosal invasion positive [ps(+)] histologically. We analyzed clinicopathological features and prognosis of 166 Japanese patients with gastric cancer invading the subserosa, according to the growth pattern. All patients were treated in the Department of Surgery II, Kyushu University. Patients with infiltrative growth (ss gamma) were younger and their tumors were frequently undifferentiated compared to findings in those with noninfiltrative growth: expansive (ss alpha) and intermediate growth (ss beta). There was no difference in any other clinicopathological characteristic between those with infiltrative and noninfiltrative growth tumors. The 10-year survival rate was 66.7% for the infiltrative type and 54.2% for the noninfiltrative type, with no statistically significant difference. Lymph node metastasis, curative resection, and extended lymph node dissection, but not growth pattern, proved to be independent prognostic factors, as determined by multivariate analysis. Our findings suggest that it is not the growth pattern which affects the prognosis of ss cancers. Extensive lymph node dissection should be done when lymph node metastasis is present.

“…As shown by other investigators, lymph node metastasis ( P < 0.01). occurred in about one-half of all the treated patients [2,6,8]. We reported that gastric cancer with lymph node metastasis has a high potential for growth and metastasis and worsens the prognosis [9,10].…”
