Plain English Summary
Background and study aims
Gastric cancer (GC) is the second leading cause of cancer-related mortality worldwide. Therefore, identifying the predictive factors for surgical morbidity, disease recurrence, and long-term survival is necessary for preventing GC patient mortality. We aimed to evaluate the factors that contribute to the poor prognoses of GC patients.
Who can participate?
All post-curative resection gastric cancer patients.
What does the study involve?
All patients underwent total or distal gastrectomy, and we gave chemotherapy to the patient whom a state has good.
What are the possible benefits and risks of participating?
No benefits and risks of participating.
Where is the study run from?
Onomichi General Hospital
When is the study starting and how long is it expected to run for?
May 2011 to June 2017.
Who is funding the study?
Investigator-initiated and funded.

All patients underwent total or distal gastrectomy and D1+ or D2 lymph node dissection in accordance with the Japanese Gastric Cancer Treatment Guidelines published in 2010 (ver. 3). All patients were histologically confirmed to have stage I, II, or III gastric adenocarcinomas and underwent total or distal gastrectomy. The total duration of observation and follow-up were conducted within 5 years post-operation, or until death.
Primary outcome measure
1. Disease-free survival is defined as the time between the date of surgery and disease recurrence or the last available follow-up.
2. Overall survival is defined as the time between the date of surgery and death or the last available follow-up.
Secondary outcome measures
1. Absolute neutrophil and lymphocyte counts are measured using routine blood and biochemical tests on the day before surgery.
2. Serum albumin is measured using routine blood and biochemical tests on the day before surgery.
3. C-reactive protein (CRP) concentrations are measured using routine blood and biochemical tests on the day before surgery.
4. Prognosis is measured using the modified Glasgow Prognosis Score, perineural invasion and neutrophil to lymphocyte ratio on the day before surgery.
5. Diagnosis is determined using surgical pathology reports after surgery.
