Symptoms and Testing information for PDGFR and cKIT Gastrointestinal Stromal Tumors Test

Gastrointestinal stromal tumors (GISTs) represent a unique subset of cancers that originate from the digestive tract’s connective tissue or, less frequently, from the omentum, mesentery, or retroperitoneum. The discovery of mutations in the Platelet-Derived Growth Factor Receptor Alpha (PDGFRA) and the proto-oncogene cKIT (CD117) has significantly advanced our understanding of the pathogenesis of these tumors. This has led to the development of targeted therapies, making the testing for these mutations an essential aspect of managing patients with GISTs.

Symptoms of Gastrointestinal Stromal Tumors

GISTs can present with a variety of symptoms, which often depend on the tumor’s size and location within the gastrointestinal tract. Common symptoms include:

  • Abdominal pain or discomfort
  • Palpable abdominal mass
  • Gastrointestinal bleeding, which can lead to anemia and symptoms of fatigue and weakness
  • Nausea and vomiting, especially if the tumor is causing a blockage
  • Early satiety (feeling full after eating only a small amount of food)
  • Weight loss

It’s important to note that some individuals with GISTs may not exhibit any symptoms, and the tumors are often discovered incidentally during imaging studies for unrelated issues.

Importance of PDGFR and cKIT Testing in GISTs

Testing for mutations in PDGFR and cKIT is crucial for several reasons. Firstly, it helps in confirming the diagnosis of GISTs, as these mutations are highly specific for this type of tumor. Secondly, the presence of these mutations can predict the response to targeted therapies, such as imatinib (Gleevec), which specifically inhibits the tyrosine kinase activity of the cKIT and PDGFRA proteins. Lastly, the mutation status can provide prognostic information, helping to estimate the potential aggressiveness of the tumor and guide treatment decisions.

PDGFR and cKIT Gastrointestinal Stromal Tumors Test

DNA Labs UAE offers a comprehensive testing service for PDGFR and cKIT mutations in patients diagnosed with or suspected of having GISTs. This test is designed to detect the presence of mutations in the genes encoding for the PDGFRA and cKIT proteins, which are critical in the pathogenesis of these tumors. The test involves a simple blood draw or a biopsy of the tumor tissue, which is then analyzed using advanced molecular techniques to identify any mutations.

Test Cost

The cost of the PDGFR and cKIT Gastrointestinal Stromal Tumors Test at DNA Labs UAE is 3000 AED. This includes the collection of the sample, the analysis, and a comprehensive report detailing the findings and their implications for treatment and prognosis.


Gastrointestinal stromal tumors are a complex disease that requires precise diagnostic tools for effective management. The PDGFR and cKIT Gastrointestinal Stromal Tumors Test provided by DNA Labs UAE represents a crucial step in diagnosing and tailoring treatment for patients with this condition. By identifying the specific mutations present in the tumor, clinicians can make informed decisions about the most appropriate therapeutic strategies, potentially improving outcomes for patients with GISTs.
