Resectable Gastric Cancer

Gastric cancer has one of the leading positions in the world in the prevalence and mortality among malignant tumors. The results of surgical treatment of locally advanced gastric cancer remain generally poor due to the high rate of relapse after surgery. Currently, perioperative (pre- and postoperative) chemotherapy in combination with surgery is recommended for patients with stage ≥IB resectable gastric cancer. We analyzed the studies devoted to the problem of choosing the optimal regimen of perioperative chemotherapy in locally advanced and oligometastatic gastric cancer. The highest efficacy was observed in the taxan-containing regimen FLOT which allowed to increase the median overall survival up to 50 months in a randomized controlled phase III trial. The use of perioperative chemotherapy with anti-Her2 therapy, immunotherapy or any other biologic drug remains investigational.

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.

Abstract The standard treatment for locally advanced gastric cancer differs across the world. In western countries, perioperative chemotherapy or postoperative adjuvant chemoradiotherapy are the preferred treatment options, whereas in Asia, D2 gastrectomy followed by postoperative adjuvant chemotherapy is standard. In Japan, adjuvant chemotherapy with S-1 is the standard treatment for pStage II gastric cancer, whereas adjuvant chemotherapy with a doublet regimen is preferred for pStage III gastric cancer. The efficacy of preoperative neoadjuvant chemotherapy using S-1 plus cisplatin, has been investigated in selected patients with expected poor survival outcomes. To expand the indications for neoadjuvant chemotherapy, a clinical trial investigating the efficacy of preoperative S-1 plus oxaliplatin in patients with cStage III (cT3-4N1-3) gastric cancer (JCOG1509) is ongoing in Japan. The addition of immune checkpoint inhibitors to cytotoxic chemotherapy also seems promising and is being investigated in international randomized clinical trials. Although we have to await the final results of these studies, preoperative neoadjuvant chemotherapy is a promising treatment strategy and likely to become standard treatment for locally advanced gastric cancer in Japan.

Abstract Background Curing locally advanced gastric cancer through surgery alone is difficult. Adjuvant and neoadjuvant chemotherapy bring potential benefits to more patients with gastric cancer based on several clinical trials. According to phase II studies and guidelines, SOX regimen as neoadjuvant chemotherapy is efficient. However, the optimal duration of neoadjuvant chemotherapy has not been established. In this study, we will evaluate the efficacy and safety of different cycles of SOX as neoadjuvant chemotherapy for patients with locally advanced gastric cancer. Methods RESONANCE-II trial is a prospective, multicenter, randomized, controlled phase III study which will enroll 524 patients in total. Eligible patients will be registered, pre-enrolled and receive three cycles of SOX, after which tumor response evaluations will be carried out. Those who show stable disease or progressive disease will be excluded. Patients showing complete response or partial response will be enrolled and assigned into either group A for another three cycles of SOX (six cycles in total) followed by D2 surgery; or group B for D2 surgery (three cycles in total). The primary endpoint is the rate of pathological complete response and the secondary endpoints are R0 resection rate, three-year disease-free survival, five-year overall survival, and safety. Discussion This study is the first phase III randomized trial to compare the cycles of neoadjuvant chemotherapy using SOX for resectable locally advanced cancer. Based on a total of six to eight cycles of perioperative chemotherapy usually applied in locally advanced gastric cancer, patients in group A can be considered to have completed all perioperative chemotherapy, the results of which may suggest the feasibility of using chemotherapy only before surgery in gastric cancer.

AbstractWhether extensive intraoperative peritoneal lavage (EIPL) after gastrectomy is beneficial to patients with locally advanced gastric cancer (AGC) is not clear. This phase 3, multicenter, parallel-group, prospective randomized study (NCT02745509) recruits patients between April 2016 and November 2017. Eligible patients who had been histologically proven AGC with T3/4NxM0 stage are randomly assigned (1:1) to either surgery alone or surgery plus EIPL. The results of the two groups are analyzed in the intent-to-treat population. A total of 662 patients with AGC (329 patients in the surgery alone group, and 333 in the surgery plus EIPL group) are included in the study. The primary endpoint is 3-year overall survival (OS). The secondary endpoints include 3-year disease free survival (DFS), 3-year peritoneal recurrence-free survival (reported in this manuscript) and 30-day postoperative complication and mortality (previously reported). The trial meets pre-specified endpoints. Estimated 3-year OS rates are 68.5% in the surgery alone group and 70.6% in the surgery plus EIPL group (log-rank p = 0.77). 3-year DFS rates are 61.2% in the surgery alone group and 66.0% in the surgery plus EIPL group (log-rank p = 0.24). The pattern of disease recurrence is similar in the two groups. In conclusion, EIPL does not improve the 3-year survival rate in AGC patients.
