Clinical Trial: Prognosis of Signet Ring Cells in Upper Digestive Neoplasms

Study Status: Completed
Recruit Status: Completed
Study Type: Observational




Official Title: Has the Quota of Signet Ring Cells an Influence on Prognosis and Treatment Strategy in the Upper GI Tract Adenocarcinomas?

Brief Summary:

Background • A major increase in incidence of signet ring cell adenocarcinomas (ADCI) of the upper digestive tract in western countries

  • Discordant results in the literature concerning the prognosis value of the presence of signet ring cells.
  • Preliminary data suggesting (i) an advanced stage at time of diagnosis, (ii) more often in the form of carcinose, (iii) a more pejorative prognosis, (iv) a recurrence more frequent, more quickly, and more often in the form of peritoneal carcinose, (v) a chemo resistance (vi) the need for a specific therapeutic strategy compared to non-signet ring cell adenocarcinomas.

Primary objective To test the hypothesis that 5-year survival rate is significantly lower in the signet ring cells (SRC) adenocarcinoma when compared to non-SRC adenocarcinoma in the upper digestive tract

Secondary objectives

  • Impact of neoadjuvant CT on overall survival
  • Impact and differential diagnostic value of linitis
  • R0 resection rates
  • 3 years recurrence free survival
  • Overall 3 years survival
  • Prognostic factors
  • Prognostic value of the presence of a minority quota of signet ring cell
  • Objective response rate after medical treatment (chemotherapy, radiochemotherapy) in non-resected patients
  • Tolerance of (radio) chemotherapy for ADCI

Methodology Intention to treat retrospective case-
