Brief Summary

The genetic background for cancer treatment may also be different among different areas and races. There is lack of Taiwanese data of genetic alterations in cancer patients. To understand the landscape of genetic aberrations of cancer in Taiwan, large scale survey of the cancer patients is indicated. In this pilot study, the investigators want to evaluate the landscape of genetic aberrations in cancer patients via oncopaenl test and collect the clinical data of the patients. The result of the oncopanel test will be returned to patient and their attending physician for reference of their further treatment. In addition, the investigators want to correlate the clinical outcome with the genetic aberrations of the cancer patients in Taiwan. Gastrointestinal stromal tumor (GIST) is a rare cancer compared with the other solid tumors. C-KIT or PDGFRA mutation is found in approximately 85-90% of GISTs. Imatinib, a tyrosine kinase inhibitor targeting c-KIT, has been used to treat advanced GIST successfully since 2000. However, resistance to imatinib may develop either via secondary mutation of c-KIT or primary resistance to those with wild type c-KIT and PDGFRA. Although sunitinib and regorafenib have been approved as second and third line of treatment for advanced GIST, the progression free survival were only 6.8 and 4.8 months, respectively. The genetic landscape of GIST with wild type c-KIT and PDGFRA was less studied. In the current study, the investigators want to focus on the GISTs with wild type c-KIT and PDGFRA to perform the NGS oncopanel for these patients. Then the investigators can understand the genetic aberrations of these patients (wild type GIST) and help for searching the potential treatment targets to them.

Outcome Measures

Primary Outcomes (1)

  • genetic profiles in gastrointestinal stromal tumor (GIST) patients

    To evaluate the genetic profiles in gastrointestinal stromal tumor (GIST) patients without c-KIT and PDGFRA mutation (wild type) in Taiwan.

    5-year time frame

Secondary Outcomes (3)

  • Collect clinical data of wild type GIST patients

    5-year time frame

  • To correlate the clinical characteristics, treatment and outcome of wild type GIST patients with the genetic profile in Taiwan.

    5-year time frame

  • To help for search the potential targeted agents for the treatment of these wild type GIST patients

    5-year time frame

Study Population

Wild Type Gastrointestinal stromal tumor (GIST)

You may qualify if:

  • Pathologically confirmed GIST.
  • The tumors can be resected, unresectable, recurrent or metastatic and the patients had ever received, are receiving or will receive systemic treatment (adjuvant, neoadjuvant or salvage TKI or other targeted agents)
  • The tumors were tested for wild type c-KIT and PDGFRA.
  • There are archived tumor samples available or the patients agree to do tumor biopsy for oncopanel test if there is no tumor sample or not enough tumor sample available.
  • The patients who are systemic treatment naïve or have received prior systemic treatment are all eligible.
  • Age - the legal age.
  • Life expectancy greater than 6 months
  • Capable of understanding and complying with the protocol requirements and signed informed consent.

You may not qualify if:

  • Patients will be excluded from the study if they meet any of the following criteria:
  • Inability and unwillingness to give informed consent
  • Patients do not agree to provide archived tumor samples and blood samples or they do not agree to do tumor biopsy when archived tumor samples are not available.
  • Patients refused for collection of clinical data and follow up.
  • Mental status is not fit for further treatment or data collection.
