Study Details
Study Description
Brief Summary
Protocol Objectives Establish a platform for sharing integrated database of genetic background, clinical information, and therapeutic outcomes in locally advanced and recurrent/metastatic ESCC.
To enroll a total of 400 ESCC patients with different ages and stages according to the eligibility criteria defined in section 5 and section 6.To perform NGS analysis of ESCC tumor tissues, and correlated with the clinical characteristics and treatment outcomes of ESCC patients.To compare the difference of the genetic and molecular profiles among different age groups of ESCC patients.To reveal the evolution changes of genetic and molecular profiles of ESCC by comparing the difference of genetic and molecular alterations between primary and recurrent ESCC and between locally advanced and metastatic ESCC. 。 Study Method, Procedures, and Implementation Status Sample size: 400 patients with ESCC who fit inclusion criteria and exclusion criteria listed in session 6 of the study proposal.
-
To meet the study object of investigating "the difference of the genetic and molecular profiles among different age groups", a minimum of 75 young ESCC patients (with age of ESCC diagnosis at 20-45 years old) and a minimum of 75 elderly ESCC patients (with age of ESCC diagnosis at ≥ 75 years old) will be recruited.
-
To meet the study object of investigating "the evolution changes of genetic and molecular profiles of ESCC", an approximate of 100 recurrent or metastatic ESCC tumors will be included.

Detailed Description
Esophageal squamous cell carcinoma (ESCC) is a major histological subtype of esophageal cancer in Asia including Taiwan, with distinct epidemiological, clinical, and pathological features from esophageal adenocarcinoma which is commonly seen in Western countries. For decades, esophageal cancer has ranked as one of top leading causes of cancer-related death in Taiwan. Most ESCC patients are men, and present with locally advanced or metastatic disease at diagnosis. Chemoradiotherapy and surgery are commonly employed in patients with locally advanced ESCC; however, more than half of them would eventually develop disease recurrence or distant metastasis. Chemotherapy is the mainstay of treatment for patients with recurrent and metastatic ESCC; unfortunately, the efficacy of chemotherapy has been limited and unsatisfactory. Even anti-program cell death protein 1 (PD-1)- based immunotherapy has recently become an important treatment modality for advanced ESCC, the prognosis of these patients remains poor with a median survival time around a year. Therefore, a better understanding of this deadly disease is crucial for finding better therapeutic strategies for these patients.
A trend of increasing incidence in young age (less than 45-years-old) has been observed in Taiwan recently. This disease not only could devastate these young patients but also would cause huge financial impact to their families. In one of our previous study focusing on the prognosis of metastatic or recurrent ESCC patients treated with systemic chemotherapy, the investigators found that elderly ESCC patients might have better prognosis than young patients. Additionally, the preliminary data of our recent works suggest that the genetic alterations of ESCC in patients of different age groups might be distinct. However, whether the genetic alterations are significantly different among ESCC patients of different age groups and whether the differences exhibit any prognostic or predictive impact have not yet been systematically investigated.
The investigators thus proposed this multi-center research project to address the fore-mentioned questions by collecting tumor tissues from ESCC patients for next-generation sequencing analysis with a panel of cancer-related genes, and creating a platform for data storage and sharing. The specific aims of this project are (1) to establish the tumor genetic and molecular profiles of ESCC in Taiwan, (2) to compare the difference of the genetic and molecular profiles among different age groups of ESCC patients, and (3) to reveal the evolution changes of genetic and molecular profiles of ESCC. The long-term goals of this study are to help implement personalized therapy, to develop novel therapy, and to improve outcomes of patients with ESCC.
