研究概览
简要总结
Background:
The number of patients with esophageal cancer keeps rising. For many patients, a combination of surgery, chemotherapy, and radiation is necessary to completely treat the disease. Usually, patients receive chemotherapy and radiation at the same time followed by surgery to remove the part of the esophagus with the tumor (Neoadjuvant chemoradiotherapy (nCRT)). Researchers want to learn how to make this treatment more effective.
Objective:
To see if biopsies before treatment can show which patients will do the best with a combination of chemotherapy, radiation, and surgery.
Eligibility:
Adults at least 18 years old with esophageal adenocarcinoma or squamous cell carcinoma who should be treated with chemotherapy, radiation, and surgery.
Design:
Patients will undergo standard testing that is routine for all patients with this disease. These tests include:
Medical history
Physical exam with activity and nutritional assessment
Standard lab tests
Imaging studies including a computerized axial tomography (CAT) scan and positron-emission tomography (PET) scan
Breathing test into a machine to measure size and function of lungs.
Biopsy for a small sample of tumor is removed by esophagogastroduodenoscopy (EGD): A tube inserted into the mouth under anesthesia
Endoscopic ultrasound is performed in some but not all patients.
Patients will have nCRT at the clinic or with their local doctor.
In 6 -12 weeks after nCRT, patients will undergo surgery with:
- A robotically-assisted, minimally-invasive esophagectomy
- Or, a traditional, open approach.
After surgery, patients are usually in the hospital for 2 weeks and have a feeding tube for at least 2 weeks and potentially longer until they are eating enough to not lose weight.
Patients will return for follow-up visits with labs and CAT scans every 6 months for the first two years then every year afterwards.
详细描述
Background:
- The incidence of esophageal cancer continues to increase with an estimated 16,900 new cases and 15,700 deaths in 2016. Esophageal adenocarcinoma (EAC) is the dominant histology in the United States and accounts for the rising incidence; the incidence of esophageal squamous cell cancer (ESCC) remains stable.
- Neoadjuvant chemoradiotherapy (nCRT) followed by esophagectomy is now a standard approach for locally advanced, operable esophageal cancer.
- A survival advantage compared to surgery alone was demonstrated in the phase III Chemo
Radiotherapy for Oesophageal cancer followed by Surgery Study (CROSS) trial.
- Patients who experience a pathological complete response (pCR) following neoadjuvant therapy are most likely to have long-term survival.
- Presently, accurate assessment of pathologic response requires esophagectomy. Positron-emissions tomography (fludeoxyglucose (FDG-PET)) and endoscopic evaluation with biopsies fail to detect cancer in a significant percentage of patients with residual disease following neoadjuvant therapy.
- Currently there are no validated tissue or serologic biomarkers which can be used to guide surgical management of esophageal cancer patients based on response to nCRT.

结局指标
主要结局
BH3 Profiling of Pre-neoadjuvant Tumor Biopsy and Outcome of Pathological Complete Response After Neoadjuvant Chemoradiotherapy in Patients With Esophageal Adenocarcinoma or Squamous Cell Carcinoma
时间窗: Pre-neoadjuvant therapy within 4 weeks, and after neoadjuvant therapy >4 weeks but prior to surgery
Two tumor samples and two normal esophagus samples will be obtained for BH3 profiling of pre-neoadjuvant tumor biopsy and outcome of pathological complete response after neoadjuvant chemoradiotherapy in patients with esophageal adenocarcinoma or squamous cell carcinoma. Response will be defined by the Mandard Score. Major response with no viable tumor (Grade 1) and \<10% viable tumor (Grade 2) versus non major response of \>10% viable tumor (Grade 3-5) as assessed by final pathology. Grade 1-2 is better survival than Grade 3-5.
Metabolomic Signature in Tumor, Blood, or Urine and Outcome of Pathological Complete Response After Neoadjuvant Chemoradiotherapy in Patients With Esophageal Adenocarcinoma or Squamous Cell Carcinoma
时间窗: After neoadjuvant therapy >4 weeks but prior to surgery
Specimens of normal esophagus, esophageal tumors, blood, or urine will be analyzed to determine specific signatures and outcome of pathological complete response after neoadjuvant chemoradiotherapy in patients with esophageal adenocarcinoma or squamous cell carcinoma. Response will be defined by the Mandard Score. Major response with no viable tumor (Grade 1) and \<10% viable tumor (Grade 2) versus non major response of \>10% viable tumor (Grade 3-5) as assessed by final pathology. Grade 1-2 is better survival than Grade 3-5.
