POF Versus FOLFOX Plus IP Paclitaxel in AGC

Recruitment & Eligibility

Status: UNKNOWN

Sex: All

Target Recruitment: 260

Inclusion Criteria

18-75 years old;
Patients must have histologically or cytologically confirmed metastatic or unresectable gastric or gastroesophageal junction (GEJ) adenocarcinoma. GEJ adenocarcinoma may be classified according to Siewert's classification type I, II, or III
Histological documentation of local recurrence or metastasis is strongly encouraged, unless the risk of such a procedure outweighs the potential benefit of confirming the metastatic disease.
If no histologic confirmation, then the metastases or recurrence will require documentation by a 2nd radiographic procedure (eg. PET/CT scan or MRI in addition to the CT scan). If the imaging procedure does not confirm recurrent or metastatic disease, biopsy confirmation will be required.
Patients must have ascites or peritoneal carcinomatosis confirmed by image (CT or MR or US or others) operation.
Patients may have received no prior chemotherapy for metastatic or unresectable disease. Patients may have received prior adjuvant therapy (chemotherapy and/or chemoradiation) if more than 6 months have elapsed between the end of adjuvant therapy and registration.
Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0-1;
An expected survival of ≥ 3 months;
Major organ function has to meet the following criteria; (1) For results of blood routine test:
Hemoglobin (HB) ≥ 80g / L,
ANC(absolute neutrophil count) ≥ 1.5 × 109 / L,
PLT(blood platelet) ≥ 75 × 109 / L, (2) For results of biochemical tests:
BLT（total bilirubin） ≤ 1.25 times the upper limit of normal (ULN),
ALT(Alanine aminotransferase) and AST(aspartate aminotransferase ) ≤ 2.5 × ·ULN, liver metastases, if any, the ALT and AST≤ 5 × ULN,
Serum Cr（creatinine）≤1ULN, Endogenous creatinine clearance rate >50ml/min;
The patient has a PT（prothrombintime） (INR international normalized ratio) < or = to 1.5 and an PTT（Partial Thromboplastin Time）< than or = to 3 seconds above the upper limits of normal if the patientia t is not on anticoagulation. ·If a patient is on full-dose anticoagulants, the following criteria should be met for enrollment:
The patient must have an in-range INR (usually between 2 and 3) on a stable dose of warfarin or on stable dose of LMW(Low molecular weight) heparin
The patient must not have active bleeding or pathological conditions that carry high risk of bleeding (e.g. tumor involving major vessels, known varices)
Pregnancy test (serum or urine) has to be performed for woman of childbearing age within 7 days before enrolment and the test result must be negative.
Men and women of childbearing potential must be willing to consent to using effective contraception while on treatment and for at least 3 months thereafter.
Ability to understand informed consent and signing of written informed consent document prior to initiation of protocol therapy.

Exclusion Criteria

Patients who have received previous chemotherapy for the treatment of metastatic or unresectable gastric or GEJ adenocarcinoma are ineligible.

Patients who have received previous pre- or post-operative chemotherapy or chemoradiation are ineligible if therapy was completed less than 6 months prior to study registration. Patients must have recovered from adverse events from any previous therapy.
Patients with a history of another neoplastic disease within the past three years, excluding basal cell carcinoma of the skin, cervical carcinoma in situ, or nonmetastatic prostate cancer.
Patients with brain or central nervous system metastases, including leptomeningeal disease.
Pregnant (positive pregnancy test) or breast feeding.
Serious, non-healing wound, ulcer, or bone fracture.
Significant cardiac disease as defined as:

unstable angina, New York Heart Association (NYHA) grade II or greater, congestive heart failure, history of myocardial infarction within 6 months Evidence of bleeding diathesis or coagulopathy.

History of a stroke or CVA within 6 months
Clinically significant peripheral vascular disease.
Inability to comply with study and/or follow-up procedures.
Patients with any other medical condition or reason, in that investigator's opinion, makes the patient unstable to participate in a clinical trial.

Group	Intervention	Description
POF	POF	The POF regimen consisted of a 3-hour infusion of paclitaxel (135 mg/m2) followed by oxaliplatin (85 mg/m2) and Calcium Levofolinate (200 mg/m2).Subsequently, a 46-hour infusion of fluorouracil (2400 mg/m2) was administered using an ambulatory pump, repeating the cycle every 14 days. The combined chemotheraphy will be treated for 9 circle. then，the capetabine was allowed
