简要总结
This randomized phase II trial studies how well fludeoxyglucose F-18 (FDG)/positron emission tomography (PET) directed treatment improves response in patients with stomach or gastroesophageal junction cancer that has not spread past the stomach and is not responding to the usual treatment. PET scans are a different way to take pictures of cancer and can be used to look at how much energy (such as glucose) is being used by the cancer. Using PET scans early to monitor the success of treatment may allow doctors to measure response and change treatment accordingly.
详细描述
Pre-registered patients receive standard pre-operative chemotherapy comprising epirubicin intravenously 50mg/m^2 (IV) on day 1; oxaliplatin 130 mg/m^2 IV or cisplatin 60 mg/m^2 IV on day 1; and capecitabine 625 mg/m^2 orally (PO) twice daily (BID) or fluorouracil 200 mg/m^2/day IV continuously on days 1-21; and undergo FDG-PET following course 1 (days 15-19). Patients defined as FDG-PET non-responders are registered and randomized to 1 of 2 treatment arms.
Primary objective
To assess and compare the overall survival (OS) of patients with locally advanced gastric cancer classified as FDG-PET non-responders after one cycle of pre-operative chemotherapy randomly assigned to receive either salvage chemotherapy before and after surgery or immediate surgery followed by fluorouracil sensitized radiotherapy.
Secondary objectives
- To assess and compare progression-free survival (PFS) between the treatment arms (Arms A and B).
- To assess and compare R0 resection rate between the treatment arms (Arms A and B).
- To assess and compare pathologic complete response (pCR) rate between the treatment arms (Arms A and B).
- To assess the adverse events (AE) profile and safety of each treatment arm (Arms A and B), including post-operative mortality rate, 30-day post-operative targeted adverse events (i.e., dehiscence, significant infection, and re-operation rate).
- To examine the changes of FDG-PET SUV induced by pre-operative chemotherapy at different time points (from baseline to completion of one cycle of treatment before randomization, and 2 cycles of salvage treatment) in patients randomized to salvage treatment arm (Arm B).
- To collect measurement of fatigue and overall perception of QOL at registration of the study (Alliance registration QOL assessment study).

研究组 & 干预措施
Arm A - surgery, chemotherapy and radiation therapy
Patients undergo surgery within 42 days of completion of pre-registration chemotherapy. Beginning within 49 days of surgery, patients receive 5-FU IV continuously and capecitabine PO BID on days 1-7, and undergo 3D-CRT or IMRT QD on days 1-5. Treatment continues for 5 weeks in the absence of disease progression or unacceptable toxicity.
