Therefore, the aim of the present study was to score the degree of TCD at the invasion front (TCD 0\u20133) in a retrospective series of 445 gastric cancer patients and to compare its prognostic significance with the parameters T\u2010stage, tumor size, grade of tumor differentiation, lymph\u2010node involvement and vascular invasion. We could show that highly significant differences (p &lt; 0.0001, log\u2010rank test) existed between the 5\u2010year survival rates of patients with different degrees of TCD (TCD 0:92.3%; TCD 1:62.1 %; TCD 2: 41.2%. TCD 3:38.5%) and that these differences were independent of T\u2010stage 2, tumor size and grade of tumor differentiation. Univariate Cox regression analysis showed that in intestinaltype carcinomas, T\u2010stage (Chi\u2010square: 45.2) followed by blood vessel and lymphatic vessel invasion (Chi\u2010square: 43.6 and 40.0) had the highest prognostic value, whereas TCD (Chi\u2010square: 31.5) revealed a prognostic value quite similar to that of lymph\u2010node involvement (Chi\u2010square: 35.1). This prognostic relevance was still present in multivariate Cox regression analysis, showing that the determination of TCD provided an increase in prognostic information which significantly (p = 0.026) exceeded the information obtained by the combination of T\u2010stage and lymph\u2010node involvement. Our data suggest that TCD is a new prognostic parameter, especially in those gastric carcinomas in which lymph\u2010node involvement or vascular invasion are not present.<\/jats:p>","DOI":"10.1002\/ijc.2910500208","type":"journal-article","created":{"date-parts":[[2007,2,19]],"date-time":"2007-02-19T22:43:13Z","timestamp":1171924993000},"page":"202-207","source":"Crossref","is-referenced-by-count":82,"title":["Tumor\u2010cell dissociation at the invasion front: A new prognostic parameter in gastric cancer patients"],"prefix":"10.1002","volume":"50","author":[{"given":"H.
