Advanced Stages

Gastric cancer is one of the most common cancers and a main cause of cancer-related death worldwide, since the majority of patients suffering of this malignancy are usually faced with a poor prognosis due to diagnosis at later stages. In order to improve treatment outcomes, the association of surgery with chemo and/or radiotherapy (multimodal therapy) has become the standard treatment for locally advanced stages. However, despite several treatment options currently available for management of these tumors, perioperative chemotherapy has been mainly accepted for the comprehensive therapeutic strategy including an appropriated D2-gastrectomy. This manuscript presents a (nonsystematic) critical review about the use of perioperative chemotherapy, with a special focus on the drugs delivery.

Locally Advanced Gastric Cancer

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.

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.

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.

Gastric cancer is one of the most common neoplasms and a main cause of cancer-related mortality worldwide. Surgery remains the mainstay for cure and is considered for all patients with potentially curable disease. However, despite the fact that surgery alone usually leads to favorable outcomes in early stage disease, late diagnosis usually means a poor prognosis. In these settings, multimodal therapy has become the established treatment for locally advanced tumors, while the high risk of locoregional relapse has favored the inclusion of radiotherapy in the comprehensive therapeutic strategy. We provide a critical, non-systematic review of gastric cancer and discuss the role of perioperative radiation therapy in its treatment.

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.

Locally Advanced Gastric Cancer

The purpose of the study was a systemic literature review on data regarding the efficacy, safety and prospects for the use of adjuvant chemotherapy for locally advanced gastric cancer.Material and Methods. The study contained a thorough literary analysis of the results of international studies on the use of preoperative and postoperative chemotherapy for locally advanced gastric cancer. Relevant sources were searched in Medlin and Cochrane Library databases, and publications from 2001 to 2019 were included. Of all the studies analyzed, 28 were used to write the systematic review.Results. The increase in survival rates was mainly achieved due to the use of a multimodal approach to the treatment of gastric cancer. The effectiveness of this approach, which combined surgery with chemotherapy or chemoradiotherapy, was proven in several large clinical studies. However, despite the large number of treatment options for locally advanced gastric cancer, there is still no single standard for the management of patients with this disease. One of the treatment options successfully practiced in a number of leading countries is the use of adjuvant chemo/chemoradiation therapy.Conclusion. Analysis of the literature data of the last 18 years has shown the high relevance of studies on adjuvant chemotherapy for gastric cancer and the need to continue further study of this problem.
