Urokinase-type Plasminogen Activator Receptor and Gastroesophageal Cancer

The aim of this study is to investigate urokinase Plasminogen Activator Receptor (uPAR) microexpression in gastroesophageal cancer (adenocarcinomas) both qualitatively and semi-quantitatively and to evaluate if it offers a possibility for future imagining purposes.

About this study

  • Sections of the tumor tissue will be HE stained.
  • Sections of the tumor tissue will be stained with an uPAR antibody for immunohistochemistry.
  • Immunohistochemical staining against cytokeratin which colors cancer cells will be made to assist the observer in the evaluation of uPAR microexpression pattern.
  • A semiqualitative scale corresponding to the level of uPAR expression will be made.
  • Quantitative polymerase chain reaction will be used to validate the immunohistochemistry uPAR expression pattern.
  • An electronic scoring system (digital pathology) will be trained to access the expression of uPAR in both tumor- and normal tissue.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age ≥18 years old.
  • Patients who underwent curatively intended surgery for gastroesophageal cancer
  • Patients who underwent surgery after 01-01-2016.

Exclusion criteria

  • Patients who applied for an exception from medical research at the "National Registry of Tissue Use."
  • Patients with other histological subtypes than adenocarcinoma.

Treatment and study plan

uPAR immunohistochemistry

Other

Resected esophageal cancer will be qualitatively and semi-quantitatively analyzed for uPAR expression

Primary outcomes

  1. uPAR microexpression

    Time frame: Up to 6 months

    Our primary objective is to investigate uPAR microexpression in gastroesophageal adenocarcinomas both qualitatively and semi-quantitatively. This will be done by a pathology analysis of gastroesophageal cancer resections.

  2. Tumor-to-background ratio

    Time frame: Up to 6 months

    A pathology staining will determine the uPAR in the tumor compared with the healthy cells.

Secondary outcomes

  1. uPAR in patient groups

    Time frame: Up to 6 months

    Baseline statistical analysis of patient groups and their expression of uPAR in their resected tumor tissues will be made.
