OBJECTIVE: To assess whether delineation courses for radiation oncologists improve interobserver variability in target volume delineation for postoperative gastric cancer radiotherapy planning. METHODS: Twenty-nine radiation oncologists delineated target volumes in a gastric cancer patient. An experienced radiation oncologist lectured about delineation based on contouring atlas and delineation recommendations. After course, the radiation oncologists provided delineation for the same patient blind to the previous delineation...

In recent decades, there has been considerable worldwide progress in the treatment of gastric cancer. Gastrectomy with a modified D2 lymphadenectomy (sparing the distal pancreas and spleen) has increasingly gained acceptance as a preferable standard surgical approach among surgeons in the East and the West. Despite growing consensus significant differences still exist in surgical techniques in clinical trials and clinical practices secondary to variations in epidemiology, clinicopathologic features, and surgical outcomes among geographic regions...

The aim of the study was to collect the available data on central nervous system (CNS) metastases from esophageal and gastric cancer. A PubMed, EMBASE, SCOPUS, Web of Science, LILACS, Ovid and Cochrane Library search was performed. Thirty-seven studies including 779 patients were considered. Among the data extracted, treatment of tumor and brain metastases (BMs), time to BMs development, number and subsite, extracerebral metastases rate, median overall survival (OS) and prognostic factors were included. For esophageal cancer, the median OS from diagnosis of BMs was 4...

BACKGROUND: Proton-beam therapy of large abdominal cancers has been questioned due to the large variations in tissue density in the abdomen. The aim of this study was to evaluate the importance of these variations for the dose distributions produced in adjuvant radiotherapy of gastric cancer (GC), implemented with photon-based volumetric modulated arc therapy (VMAT) or with proton-beam single-field uniform-dose (SFUD) method. MATERIAL AND METHODS: Eight GC patients were included in this study...

Breast cancer is the most common malignancy in women. The most frequent metastatic sites are lung, bone, liver and brain. On the other hand, gastric metastases are rare. Synchronous bilateral breast cancer (SBBC) occurs rarely. Lobular carcinoma is the histological type most often associated with bilateral breast carcinomas and gastric metastases. We made a retrospective study including four patients followed in the Salah Azaiez Institute, for a bilateral breast cancer with gastric metastases. We analyzed the epidemiological, anatomoclinical and therapeutic particularities of this rare entity...

Staging of locally advanced gastric cancer includes imaging with computed tomography scan and laparoscopic assessment to rule out peritoneal disease or positive peritoneal washings. Preoperative and postoperative chemotherapy improves survival compared with surgery alone. After primary D2 resection, adjuvant chemotherapy with a fluorinated pyrimidine with or without a platinum agent improves survival. Inclusion of postoperative radiation therapy appears required in combination with chemotherapy in patients with less than a D1-D2 resection...

Purpose: Although Korea has the highest incidence of gastric cancer worldwide and D2-lymphadenectomies are routinely performed, radiotherapy (RT) practice patterns have not been well studied. Therefore, we examined RT usage trends for neoadjuvant/adjuvant patients and identified factors associated with RT. We also examined survival benefits and net medical cost advantages of adding RT. Materials and Methods: Patients diagnosed with gastric cancer who underwent gastrectomy from 2002-2013 were identified using National Health Insurance Service-National Sample Cohort...

OBJECTIVES: The Intergroup 0116 study has demonstrated a significant survival benefit for completely resected (R0) gastric cancer patients treated with a fluorouracil/leucovorin chemoradiotherapy regimen. However, this regimen is also toxic and less effective in terms of distant disease control. Therefore, a more efficacious and safer regimen is urgently needed. METHODS: Patients with R0 resected gastric carcinoma received up to two 21-day cycles of postoperative adjuvant preradiation and postradiation DCF chemotherapy (docetaxel 37...

Proton-Pump Inhibitors (PPIs) are commonly prescribed in the general population and in cancer patients. A supposed role in the prevention of gastric mucosal damage apparently justify their use in patients undergoing cytotoxic chemotherapy, steroids and radiotherapy on the gastro-duodenal region. They are frequently given also to patients admitted to Intensive Care Units, for the prevention of stress-related gastric ulcers. The evidence about these use of gastroprotection is reviewed. In the majority of the cases the prescription of PPIs is not justified...

Context • Gastric cancer (GC) is the fourth most common cancer and the second leading cause of cancer-related deaths in the world. The current treatments include surgery and chemotherapy, either alone or in combination with radiotherapy, but the prognosis for patients with GC is usually poor. A safe and effective chemopreventive treatment for this malignant disease is urgently needed. Objective • The study intended to investigate the effects and underlying mechanisms of plumbagin, a quinonoid constituent that is derived from the roots of the medicinal plant Plumbago zeylanica, which exhibits potent anticancer properties against a number of cancers...

BACKGROUND: Metastatic choroidal carcinomas that originated from the gastrointestinal tract are extremely rare. We report a case of suspected solitary choroidal metastasis from gastric adenocarcinoma. CASE PRESENTATION: The patient was a 60-year-old man who had undergone laparoscopic distal gastrectomy with D1+ lymphadenecetomy for gastric cancer. The clinical stage was T1bN0M0 (TNM classification), but the pathological stage was T4aN0M0 beyond expectation. Adjuvant chemotherapy with oral Tegafur, Gimeracil, Oteracil potassium (TS-1(®)) was initiated...

The successful use of immune cell checkpoint inhibitors PD-1 and PD-L1, over the past 5 y has raised the concern of using immunotherapy to treat various cancers. Epstein-Barr virus-associated gastric cancer (EBVaGC) exhibits high infiltration of lymphocytes and high amplification of immune-related genes including PD-L1 as distinguished from Epstein-Barr virus-non-associated gastric cancer (EBVnGC). Here, we presume that this PD-1/PD-L1 pathway may hinder the efficacy of adoptive T cell therapy toward EBVaGC...

ETHNOPHARMACOLOGICAL RELEVANCE: Many patients with gastric cancer seek traditional medicine consultations in Asian countries. This study aimed to investigate the prescription of Chinese herbal medicine (CHM) and its benefits for the patients with gastric cancer in Taiwan. METHODS: From the Registry for Catastrophic Illness Patients Database, we included all patients with gastric cancer whose age at diagnosis was ≥ 18 from 1997-2010 in Taiwan. We used 1:1 frequency matching by age, sex, Charlson comorbidity score, treatment and index year to compare the CHM users and non-CHM users...

Negative lymph node (NLN) count provides accurate prognostic information in patients with gastric cancer. However, it is unclear whether NLN still has prognostic value for patients received preoperative radiotherapy. In this study, Surveillance, Epidemiology, and End Results Program (SEER)-registered gastric cancer patients were used for analysis. Clinicopathological characteristics and survival time were collected. Univariate and multivariate Cox proportional hazards models were used to assess the risk factors for survival...

We report a case of advanced gastric cancer(AGC)that was resected for rebleeding after palliative radiotherapy for hemostasis. A 74-year-old man with Stage IV gastric cancer received chemotherapy and achieved stable disease. After 23 months, he experienced continuous bleeding from the tumor due to regrowth. Palliative radiotherapy was conducted to control the bleeding, and the tumor successfully achieved hemostasis. However, 6 weeks later, the patient experienced rebleeding and developed hemostatic shock. We then performed a successful emergency gastrectomy...

Case 1: An 71-year-old man underwent chemotherapy with S-1 plus trastuzumab to treat type 3 gastric cancer that was diagnosed as Stage IV tubular adenocarcinoma(T4b[Panc], N3, H0, CY1, P0, M1). For anemia and active bleeding from the tumor, transcatheter arterial embolization(TAE)was performed with metallic coils on the splenic artery. Infarction of the spleen and left pleural effusion were observed. Second-line paclitaxel(PTX)chemotherapy was administered 4 weeks after TAE. Case 2: An 76-year-old man underwent chemotherapy with S-1 plus cisplatin to treat type 3 gastric cancer that was diagnosed as Stage IV tubular adenocarcinoma(T4a, N3, H0, P1, M1)...

The patient was a 65-year-old woman. She was diagnosed with advanced gastric cancer with liver invasion. After receiving systemic chemotherapy(S-1 plus PTX)for 3 months, she underwent total gastrectomy and partial hepatectomy in May 2008. Because she developed celiac artery circumference lymph node recurrence in November 2010 during postoperative adjuvant chemotherapy consisting of S-1 plus PTX, we changed her chemotherapy regimen to CPT-11 plus CDDP. We observed an increase in the size of the lymph nodes in August 2013 and the response was poor even after switching to DOC...
