Importance: The current staging system of gastric cancer is not adequate for defining a prognosis and predicting the patients most likely to benefit from chemotherapy. Objective: To construct a survival prediction model based on specific tumor and patient characteristics that enables individualized predictions of the net survival benefit of adjuvant chemotherapy for patients with stage II or stage III gastric cancer. Design, Setting, and Participants: In this multicenter retrospective analysis, a survival prediction model was constructed using data from a training cohort of 746 patients with stage II or stage III gastric cancer who satisfied the study's inclusion criteria and underwent surgery between January 1, 2004, and December 31, 2012, at Nanfang Hospital in Guangzhou, China...

Peritoneal metastasis of gastric cancer is the main cause of death in gastric cancer patients. Peritoneal metastasis of gastric cancer is difficult to diagnose in its early stage due to lack of obvious clinical signs and symptoms, and poor treatment outcomes and prognosis are often associated with late stage peritoneal metastasis. Therefore, it is crucial to utilize effective early diagnostic tools and to improve the long-term outcomes and the prognosis of patients with advanced gastric cancer. Recently, systemic chemotherapy and intraperitoneal chemotherapy are the first line therapy, and cytoreductive operation plus abdominal cavity thermochemotherapy may be the best method in the treatment of peritoneal metastasis...

Chinese populations have many demographic similarities to Korean populations. However, the long-term survival rates of gastric cancer patients in China are still not satisfactory when compared with Korea, especially for the advanced cases. In this article, we discuss about the similarity and difference of gastric cancer treatment in terms of screening, surgical approach, stomach resection, digestive tract reconstruction, lymphadenectomy, harvested lymph nodes, operative morbidity and mortality, postoperative chemotherapy as well as follow-up between China and Korea...

DNA-binding protein inhibitor ID-1 (ID1) serves an essential role in tumor progression, and the self-renewal and pluripotency of embryonic stem cells. However, the effect of ID1 on the stemness and cancer stem cell (CSC)-like properties of gastric adenocarcinoma cells remains to be elucidated. In the present study, effective ID1 knockdown was achieved in gastric cancer (GC) cells using small interfering RNA, and the self-renewal ability and cisplatin (DDP) sensitivity of GC cells was subsequently examined. ID1 knockdown in the MKN-28 and MGC-803 cell lines was demonstrated to significantly suppress colony formation (P=0...

Surgery combined with chemotherapy is the standard treatment for gastric cancer (GC); however, chemotherapy-relative adverse effects are common and result in malnutrition and a poor prognosis. In addition, compliance to postoperative chemotherapy remains a problem. This study aimed to prospectively investigate the effect of educational and nutritional interventions on the nutritional status and compliance of GC patients undergoing postoperative chemotherapy. A total of 144 GC patients were randomized into an intervention group that received intensive individualized nutritional and educational interventions during the entire course of chemotherapy and control group that received basic nutrition care and health education during hospitalization...

Patients with peritoneal metastasis (PM) from pancreatic cancer have a short life expectancy. Systemic combination chemotherapy leads to a median overall survival of 7-8 months. Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) is a treatment alternative, where studies in patients with PM from ovarian, gastric and colorectal cancer show a high safety profile and interesting results. This case study report data on the PIPAC treatment in patients with PM from pancreatic cancer. In a standard laparoscopy, chemotherapeutics (cisplatin and doxorubicin) are nebulized within the peritoneal cavity...

The treatment of gastric cancer requires a multimodal approach to decrease the risk of locoregional and distant recurrence. The optimal timing of chemotherapy, surgery, and radiation therapy continues to be explored in ongoing trials. In the United States, surgical resection is often followed by adjuvant chemoradiation therapy or by a combination of neoadjuvant and adjuvant chemotherapy. Here we report on 4 patients with resected gastric adenocarcinoma who were treated with a combination of these 2 approaches, receiving neoadjuvant chemotherapy followed by adjuvant chemoradiation therapy...

One of the severe limitations of chemotherapy is the development of drug resistance. However, the mechanisms underlying chemotherapy resistance remain to be elucidated. Mitochondrial mediated apoptosis is a form of cell death induced by chemotherapy. Several chemotherapeutic agents have been shown to induce mitochondrial fission, and finally activate the apoptosis cascade in various cancer cells. Here, we report that the mitochondrial membrane protein 18 (MTP18) induced mitochondrial fragmentation in gastric cancer cells under doxorubicin (DOX) exposure...

A key to the successful use of targeted cancer therapy is the ability to preselect patients who are likely to benefit from the treatment according to molecular markers. Assessment for predicting therapy response is mostly done using tumor biopsies. However, these might not truly represent all of the patient's malignant cells because of tumor heterogeneity and/or clonal evolution during disease progression. One potential strategy that can complement primary tumor biopsy is the analysis of circulating tumor cells (CTCs)...

INTRODUCTION: Peritoneal tumor seeding is a common form of recurrence after gastric cancer surgery. The finding of free tumor cells and/or elevation of tumor markers in the peritoneal fluid could predict intraperitoneal tumor recurrence. The results of these examination can be used for indication of aggressive treatment modalities such as hyperthermic intraperitoneal chemotherapy (HIPEC).

BACKGROUND: Peritoneal carcinomatosis represents widespread metastatic disease throughout the abdomen and/or pelvis. Cytoreductive surgery/hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) improves the overall survival compared to standard therapy alone. The role palliative care (PC) plays however, remains poorly studied among these patients. METHODS: Patients who had previously undergone HIPEC and who underwent an inpatient admission from 7/1/2013 to 6/30/2014 were identified to determine which patients were referred for inpatient or outpatient palliative consultation...

Metastatic gastric cancer is an incurable disease. Systemic chemotherapy prolongs survival, improves symptom control, and helps maintain a better quality of life of patients with metastatic gastric cancer. HER2 testing of the primary tumor and/or the metastases is warranted before initiation of first-line treatment. This review article outlines the indication and clinical data of medical treatment of advanced gastric cancer and highlights aspects of quality of life.

The outcome of patients with locally advanced, resectable gastric cancer, or adenocarcinoma of the gastroesophageal junction is poor. In clinical trials, multimodality therapy, such as perioperative chemotherapy, preoperative or postoperative chemoradiation, or adjuvant chemotherapy led to significant increments in survival. Therefore, experts agree that patients with stage II or III disease should be offered a multidisciplinary treatment approach. However, patients are treated somewhat differently in the different regions of the world and survival rates remain far from being satisfactory...

Thomas Hayes, Elizabeth Smyth, Angela Riddell, William Allum
Gastric and esophageal tumors have a poor prognosis; approximately 15% of patients are alive at 10 years following diagnosis. Surgical resection plus adjunctive chemotherapy or chemoradiotherapy is curative in approximately 50% of patients with operable disease, but is also associated with significant morbidity. Therefore, accurate preoperative staging is required to spare patients unnecessary toxicity and futile surgery. This review evaluates the sensitivity and specificities of the modalities used to stage patients with gastroesophageal cancer...
