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-

Detailed Summary: stomach cancer signet ring cell carcinoma prognosis chemotherapy

Current Primary Outcome: 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 [ Time Frame: participants are followed until death or time point at 31 september 2010 ]

Original Primary Outcome: Same as current

Current Secondary Outcome:

  • 3 year recurrence free survival [ Time Frame: participants are followed until recurrence or time point at 31 september 2010 ]
  • Overall 3 year survival according to tumor stage, node invasion, and tumor localization [ Time Frame: participants are followed until death or time point at 31 september 2010 ]


Original Secondary Outcome: Same as current
