Significant Difference

BackgroundsPerioperative chemotherapy (PEC) and neoadjuvant chemotherapy (NAC) have become a vital part of locally advanced gastric cancer (LAGC) treatment, but the optimal duration of PEC has not been studied. The aim of this study was to demonstrate the possibility of duration reduction in PEC in the adjuvant chemotherapy (AC) phase for ypN0 patients.MethodsWe included LAGC patients who achieved ypN0 after NAC in our institution from 2005 to 2018. The risk/benefit of AC and other covariates were majorly measured by overall survival (OS) and progression-free survival (PFS). We developed a survival-tree-based model to determine the optimal PEC duration for ypN0 patients in different classes.ResultsA total of 267 R0 resection patients were included. There were 55 patients who did not receive AC. The 5-year OS was 74.34% in the non-AC group and 83.64% in the AC group with a significant difference (p = 0.012). Multivariate Cox regression revealed that both AC (AC vs. non-AC: HR, 0.49; 95%CI, 0.27–0.88; p = 0.018) and ypT stages (ypT3-4 vs. ypT0-2: HR, 2.00; 95%CI, 1.11–3.59; p = 0.021) were significant protective/risk factors on patients OS and PFS. A decision tree model for OS indicated an optimal four to six cycles of PEC, which was recommended for ypT0-2N0 patients, while a minimum of five PEC cycles was recommended for ypT3-4N0 patients.ConclusionAC treatment is still necessary for ypN0. The duration reduction could be applied for the ypT0-2N0 stage patients but may not be suitable for higher ypT stages and beyond. A multicenter-based study is required.

Abstract Perioperative treatment for locally advanced gastric cancer has been inconsistent between Japan and the Western countries. In Japan, D2 gastrectomy followed by adjuvant chemotherapy is regarded as standard treatment, while neoadjuvant or perioperative chemotherapy is considered to be a standard in the Western countries. Stomach Cancer Study Group of Japan Clinical Oncology Group (JCOG) has conducted many perioperative chemotherapy trials. After the publishing of positive results of ACTS-GC trial, stage-specific adjuvant chemotherapy protocols are planned. JCOG1104 was conducted as to demonstrate the non-inferiority of four courses of S-1 to standard eight courses of S-1, because the efficacy of S-1 appears to be sufficient in stage II. The trial failed to demonstrate the non-inferiority of four courses of S-1. S-1 for 1 year is still recognized to be a standard for stage II gastric cancer. For stage III, studies with more intensive treatments were planned as the efficacy of S-1 monotherapy seems to be insufficient. As in the Western countries, JCOG planned the perioperative chemotherapy. However, the clinical staging is a serious issue to select optimal patients for perioperative chemotherapy. JCOG conducted a prospective cohort study to evaluate the validity of clinical staging in JCOG1302A. From the results of this study, cT3-4 and cN1–3 are selected as optimal candidate for perioperative chemotherapy. JCOG1509 was conducted to demonstrate the superiority of perioperative chemotherapy to adjuvant chemotherapy in these cohorts. Perioperative chemotherapy for marginally resectable tumours such as linitis plastica or extensive nodal disease and special type of cancer like HER2 positive are also conducted.
