BReast CAncer Genes(BRCA) Expressions in Metastatic Gastric Cancer

Not Applicable
Completed
Conditions
BRCA Gene Rearrangement
Interventions
Genetic: BRCA 1
Drug: Chemotherapy
Registration Number
NCT03838406
Lead Sponsor
Chung-Ang University
Brief Summary

The investigators evaluated the incidence of BRCA loss in patients with advanced gastric cancer and observed the treatment outcome and prognosis according to BRCA loss. And the investigators evaluated the possibility of BRCA loss as a predictive and prognostic factor.

Detailed Description

Stomach cancer is still the leading cause of cancer deaths globally and is reported to be the second leading cause of cancer deaths in Korea (18.7%). Although the number of radical resection has increased due to the development of early diagnosis, many patients experience recurrence after radical resection. It is also diagnosed as a non - resectable disease locally advanced at the time of initial diagnosis, or with a metastasis. In patients with recurrent / metastatic gastric cancer, conventional palliative chemotherapy is the best treatment, and in advanced gastric cancer, combination therapy with fluoropyrimidine (fluorouracil, capecitabine, S1) and platinum (oxaliplatin, cisplatin). The progression-free survival was 3-5 months, and overall survival of 6-10 months in metastatic gastric cancer patients.

The investigators evaluated the incidence of BRCA loss in patients with advanced gastric cancer and observed the treatment outcome and prognosis according to BRCA loss. And the investigators evaluated the possibility of BRCA loss as a predictive and prognostic factor.
